FIELD OF THE INVENTION
0001The present invention relates to the field of wiring using outlets, and, more specifically, to an add-on module for adding functionality to such outlets.
BACKGROUND OF THE INVENTION
Outlets
0002The term "outlet" herein denotes an electro-mechanical device, which facilitates easy, rapid connection and disconnection of external devices to and from wiring installed within a building. An outlet commonly has a fixed connection to the wiring, and permits the easy connection of external devices as desired, commonly by means of an integrated connector in a faceplate. The outlet is normally mechanically attached to, or mounted in, a wall or similar surface. Non-limiting examples of common outlets include: telephone outlets for connecting telephones and related devices; CATV outlets for connecting television sets, VCR's, and the like; outlets used as part of LAN wiring (a.k.a. structured wiring) and electrical outlets for connecting power to electrical appliances. The term "wall" herein denotes any interior or exterior surface of a building, including, but not limited to, ceilings and floors, in addition to vertical walls.
0003Rear part of an outlet (or module) refers herein to the side facing the wall after installation, and commonly also comprises the connector to the in-wall utility wiring. Front part refers to the opposing side commonly facing the room, and commonly comprising connectors for coupling to the utility wiring.
0004The terms "data unit", "computer" and "personal computer" ("PC") are used herein interchangeably to include workstations, Personal Digital Assistants (PDA) and other data terminal equipment (DTE) with interfaces for connection to a local area network, as well as any other functional unit of a data station that serves as a data source or a data sink (or both).
LAN Environment.
0005<figref idref="f0001">Figure 1</figref> shows a typical prior art LAN environment <b>10</b>. Such a network commonly uses 10BaseT or 100BaseTX Ethernet IEEE802.3 interfaces and topology, and features a hub <b>11</b> as a concentrating device, into which all devices are connected. Devices are connected to the hub <b>11</b> by data connectors <b>14a</b>, <b>14b</b>, and <b>14c</b>, which are housed within network outlets <b>15a</b>, <b>15b</b>, and <b>15c</b> respectively. Connections to the hub <b>11</b> are via cables <b>13a</b>, <b>13b</b>, and <b>13c</b> respectively. Data connectors <b>14a</b>, <b>14b</b>, and <b>14c</b> may be, for example, type RJ-45 connectors; and cables <b>13a, 13b</b>, and <b>13c</b> may be, for example, Category 5 cabling. Such configuration is described, for example, in EIT/TIA-568 and EIA/TIA-570. The data portion of network <b>10</b> uses data units (which may be computers) <b>7a</b>, <b>7b</b>, and <b>7c</b>, which connect to network connectors <b>14a</b>, <b>14b</b>, and <b>14c</b> via cables <b>16a</b>, <b>16b</b>, and <b>16c</b>, respectively. A server <b>12</b> may also be connected to the hub <b>11</b>, and can perform the external connection functionality, as well as other server functions as applied in the art.
0006Although <figref idref="f0001">Figure 1</figref> refers to the hub <b>11</b> as a concentrating device, it is to be understood that any type of device having multiple network interfaces and supporting a suitable connectivity can be used, non-limiting examples of which include shared hubs, switches (switched hubs), routers, and gateways. Hence, the term "hub" herein denotes any such device without limitation. Furthermore, network <b>10</b> can be a packet-based network, either in-building or distributed, such as a LAN or the Internet.
Home Networking.
0007Most existing offices and some of the newly built buildings facilitate the network structure of network <b>10</b>. However, implementing such a network in existing buildings typically requires installation of new wiring infrastructure. Such installation of new wiring may be impractical, expensive and problematic. As a result, many technologies (referred to as "no new wires" technologies) have been proposed in order to facilitate a LAN in a building without adding new wiring. Some of these techniques use existing utility wiring installed primarily for other purposes such as telephone, electricity, cable television (CATV), and so forth. Such approach offers the advantage of being able to install such systems and networks without the additional and often substantial cost of installing separate wiring within the building.
0008The technical aspect for allowing the wiring to carry both the service (such as telephony, electricity and CATV) and the data communication signal commonly involves using FDM technique (Frequency Division Multiplexing). In such configuration, the service signal and the data communication signals are carried across the respective utility wiring each using a distinct frequency spectrum band. The concept of FDM is known in the art, and provides means of splitting the bandwidth carried by a medium such as wiring. In the case of a telephone wiring carrying both telephony and data communication signals, the frequency spectrum is split into a low-frequency band capable of carrying an analog telephony signal and a high-frequency band capable of carrying data communication or other signals. Such a mechanism is described, for example, in <patcit id="pcit0001" dnum="US4785448A"><text>U.S. Patent 4,785,448 to Reichert et al.</text></patcit><i>,</i> and is also widely used in xDSL systems, primarily Asymmetric Digital Subscriber Loop (ADSL) systems.
0009Either in the case of FDM or any other technique, the wiring system is commonly required to support connection of a data unit to the data communication signal carried over the medium. Furthermore, it is commonly required that such a connection will make use of a standard interface having standard data communication connector. One approach is to use dedicated stand-alone, desktop style adapter device, connected between existing outlet and the data unit. Other approaches are described herein.
Functional Outlet approach.
0010This approach involves substituting the existing service outlets with 'network' active outlets. Outlets in general (to include LAN structured wiring, electrical power outlets, telephone outlets, and cable television outlets) have evolved as passive devices being part of the wiring system house infrastructure and solely serving the purpose of providing access to the in-wall wiring. However, there is a trend towards embedding active circuitry in the outlet in order to use them as part of the home/office network, and typically to provide a standard data communication interface. In most cases, the circuits added serve the purpose of adding data interface connectivity to the outlet, added to its basic passive connectivity function.
0011An outlet supporting both telephony and data interfaces for use with telephone wiring is disclosed in <patcit id="pcit0002" dnum="US6549616B"><text>US Patent 6,549,616</text></patcit> entitled '<i>Telephone outlet for implementing a local area network over telephone lines and a local area network using such outlets</i>' to Binder. Such outlets are available as part of <i>NetHome</i>™ system from SercoNet Inc. of Southborough, MA USA.
0012Another telephone outlet is described in <patcit id="pcit0003" dnum="US6216160B"><text>US Patent 6,216,160 to Dichter</text></patcit>, entitled <i>'Automatically configurable computer network'.</i> An example of home networking over CATV coaxial cables using outlets is described in <patcit id="pcit0004" dnum="WO02065229A"><text>WO 02/065229 published 22 August, 2002</text></patcit> entitled: '<i>Cableran Networking over Coaxial Cables</i>' to Cohen <i>et al.</i> Such outlets are available as part of HomeRAN™ system from TMT Ltd. of Jerusalem, Israel. Outlets for use in conjunction with wiring carrying telephony, data and entertainment signals are disclosed in US Patent Application Publication <patcit id="pcit0005" dnum="US20030099228A"><text>US2003/0099228 to Alcock</text></patcit> entitled <i>'Local area and multimedia network using radio frequency and coaxial cable'.</i> Outlets for use with combined data and power using powerlines are described in US Patent Application Publication <patcit id="pcit0006" dnum="US20030062990A"><text>US2003/0062990 to Schaeffer et al.</text></patcit> entitled <i>'Powerline bridge apparatus'.</i> Such power outlets are available as part of PlugLAN™ by Asoka USA Corporation of San Carlos, CA USA.
0013While the active outlets have been described above with regard to networks formed over wiring used for basic services (e.g. telephone, CATV and power), it will be appreciated that the invention can be equally applied to outlets used in networks using dedicated wiring. In such a case, the outlet circuitry is used to provide additional interfaces to an outlet, beyond the basic service of single data connectivity interface. For example, it may be used to provide multiple data interfaces wherein the wiring supports single such data connection. An example of such outlet is the Network Jack<sup>™</sup> product family manufactured by 3Com™ of Santa-Clara, California, U.S.A. In addition, such outlets are described in <patcit id="pcit0007" dnum="US6108331A"><text>U.S. Patent 6,108,331 to Thompson</text></patcit> entitled <i>'Single Medium Wiring Scheme for Multiple Signal Distribution in Building and Access Port Therefor'</i> as well as U.S. Patent Application <patcit id="pcit0008" dnum="US20030112965A"><text>US 2003/0112965 Published June 19, 2003 to McNamara et al.</text></patcit> entitled <i>'Active Wall Outlet'</i>.
0014While the active outlets have been described with regard to outlets and networks based on conductive media such as wires and cables, it will be appreciated that such outlets are equally applicable in the case wherein the network medium is non-conductive, such as fiber-optical cabling. Active outlets supporting data interfaces and based on fiber optic cabling are described in U.S. Patent Application <patcit id="pcit0009" dnum="US20020146207A"><text>US 2002/0146207 Published October, 10 2002 to Chu</text></patcit>, entitled <i>'Fiber Converter Faceplate Outlet',</i> as well as in <patcit id="pcit0010" dnum="US6108331A"><text>U.S. Patent 6,108,331 to Thompson</text></patcit> entitled <i>'Single Medium Wiring Scheme for Multiple Signal Distribution in Building and Access Port Therefor'.</i> As such, the term 'wiring' as used in this application as well as in the appended claims should be interpreted to include networks based on non-conductive medium such as fiber-optics cabling.
0015While the outlets described above use active circuitry for splitting the data and service signals, passive implementations are also available. An example of such passive outlet is disclosed in <patcit id="pcit0011" dnum="WO0225920A"><text>PCT Publication WO 02/25920 to Binder</text></patcit> entitled '<i>Telephone communication system and method over local area network wiring</i>'<i>.</i> Such outlets are available as part of the etherSPLIT™ system from QLynk Communication Inc. of College Station, TX USA.
0016The described above outlets are complete and self-contained devices. As such, they can be easily installed in new houses instead of regular passive simple outlets. However, such solutions are not appropriate in the case of retrofitting existing wiring systems. In most cases, any such modification will require dismantling the existing outlets and installing the new ones having the improved features. Such activity is cumbersome, expensive and will often require professional skill. Furthermore, owing to safety aspects involved while handling hazardous voltages (such as in the powerlines and telephone lines), local regulations may require only certified personnel to handle the wiring, making it expensive and militating against a do-it-yourself approach.
0017Furthermore, as the technology and environment change in time, a need to upgrade, modify or change the outlet functionalities, features and characteristics may arise. For example, the data interface may need to be upgraded to interconnect with new standards. In another example, the circuitry may need to be upgraded to support higher bandwidth. Similarly, management and Quality of Service (QoS) functionalities may need to be either introduced or upgraded. In yet another examples, additional functionalities and interfaces may need to be added. Using complete self-contained outlets as a substitute to the existing ones also introduces the disadvantages described above.
Plug-in device.
0018One approach to adding functionality to existing outlets is by using a plug-in module. A pictorial view of such a module <b>20</b> suitable for powerlines connection is shown in <figref idref="f0002">Figure 2</figref>. The module plugs into a regular power outlet using prongs <b>22a</b> and <b>22b</b>, and provide access to a data unit via data connector <b>21</b> (shown as RJ-45 used for 10/100 Base-T IEEE802.3 interface). Optional visual indicators <b>23a</b>, <b>23b</b> and <b>23c</b> may also be employed. The prongs <b>22a</b>, <b>22b</b> are used for both the electrical connection and for the mechanical attachment of the unit <b>20</b> to the power outlet. Such plug-in modules are described in US Patent Application Publication <patcit id="pcit0012" dnum="US20020039388A"><text>US 2002/0039388 to Smart et al.</text></patcit> entitled <i>'High data-rate powerline network system and method',</i> US Patent Application Publication <patcit id="pcit0013" dnum="US20020060617A"><text>US 2002/0060617 to Walbeck et al.</text></patcit> entitled '<i>Modular power line network adapter'</i> and also in US Patent Application Publication <patcit id="pcit0014" dnum="US20030062990A"><text>US 2003/0062990 to Schaeffer, JR et al.</text></patcit> entitled '<i>Powerline bridge apparatus</i>'<i>.</i> Such a module using HomePlug™ technology are available from multiple sources such as part of PlugLink™ products by Asoka USA Corporation of San Carlos, California, USA. HomePlug is a trademark of HomePlug Powerline Alliance, Inc. of San Ramon, California, USA.
0019However, such plug-in modules are known only with regards to power outlets, and are not available for telephone or CATV outlets. Furthermore, since the outlets in general, including power outlets, were not designed to offer any mechanical support beyond a plug connection, such plug-in modules are not mechanically secured to the wall / outlet, hence such attachment is not considered sustainable and reliable. Furthermore, such plug-in modules are bulky in appearance and not aesthetic.
0020There is thus a widely recognized need for, and it would be highly advantageous to have, a method and system for allowing reliable, easy and simple upgrading of outlets, preferably without requiring professional installation.

<u>SUMMARY OF THE INVENTION</u>
0022It is therefore an object of the invention to provide a method and system for allowing easy and simple upgrading of outlets, preferably without requiring professional installation. An add-on module is used for providing additional functionality to the existing outlet.
0023The invention describes an add on module for adding functionality to outlets serving existing wiring such as telephone, power and CATV and dedicated wiring such as LAN wiring (collectively 'service wiring', 'service outlet'). Non-conductive infrastructure such as fiber optics based is also included.
0024The add-on module (or 'module' herein) is both electrically connected and mechanically attached to the existing outlet. The mechanical attachment may be permanent or detachable, wherein the latter may be by hand or with specific tools. The electrical connection may use a mechanically fixed connector or tethered connector ('dongle'). In one aspect of the present invention, the module is mounted on the existing outlet by means of attaching to the outlet surface. Such attachment may use suction force, adhesive materials (e.g. glue) or VELCRO. VELCRO is a registered trademark of Velcro Industries B.V. In another aspect of the present invention, the module is attached to the sides of the outlets. Such attachment may use pressure or eccentric levers or securing strap. In another aspect of the present invention, the module is attached by inserting tabs between the outlet and the wall. In another aspect of the present invention, the module is attached by fastening screws, wherein the screws are inserted via the module and the holes in the outlets.
0025In another aspect of the present invention, the module is attached to the outlet by using a mechanical adapter.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
0039The principles and operation of a network according to the present invention may be understood with reference to the drawings and the accompanying description. The drawings and descriptions are conceptual only. In actual practice, a single component can implement one or more functions; alternatively, each function can be implemented by a plurality of components and circuits. In the drawings and descriptions, identical reference numerals indicate those components that are common to different embodiments or configurations.
Module.
0040The present invention relates to a module that both connects electrically to an existing outlet and is also mechanically attached thereto. For the sake of simplicity, the invention will be herein first described with respect to a module for use in conjunction with a telephone outlet, in order to provide the electrical connection thereto. Front and rear views of a basic exemplary telephone module <b>30</b> are respectively shown in <figref idref="f0003">Figure 3b and 3a</figref>. An RJ-11 telephone plug <b>31</b> is mounted on a rear surface of the module <b>30</b> so as to protrude outwardly therefrom for connecting to the outlet RJ-11 telephone socket On the front surface of the module there are provided two RJ-11 sockets <b>32a</b> and <b>32b,</b> commonly in order to retain the telephone connectivity, and a RJ-45 connector <b>34</b> for data communication connection (such as common 10/100Base-T Ethernet interface). The module may also employ visual indicators such as <b>33a</b> and <b>33b</b>.
Surface attachment.
0041In one or more embodiments of the present invention, the module is mechanically attached to the front surface of an existing outlet. This may be done using suction, for example.
0042In one or more embodiments of the present invention, the mechanical attachment uses suction for the mechanical attachment. <figref idref="f0004">Figure 4a</figref> shows such a module where suction is used to attach the module to the front surface of an existing outlet. Added to the basic module <b>30,</b> the module <b>40</b> comprises two suction pads <b>41a</b> and <b>41b</b>, which upon being pressed against the existing outlet <b>42</b> surface as shown in <figref idref="f0005">Figure 4b</figref>, become attached thereto. Simultaneously, the connector <b>31</b> is mated with connector <b>43</b>. While two suction units <b>41a</b> and <b>41b</b> are illustrated, any number of such units may be used providing that sufficient suction is created to support the weight of the module. A pictorial view of such a module <b>40</b> is shown in <figref idref="f0006">Figure 4c</figref>, further showing a release lever <b>44</b> so that depressing the release lever <b>44</b> releases the connector <b>31</b> in order to detach the module <b>40</b> from the outlet <b>42</b>.
0043According to another embodiment of the invention, the module is mechanically attached to the front surface of an existing outlet using adhesive material such as glue or adhesive stickers. The adhesive material may be applied to all or part of the surface area of the existing outlet, wherein contact with the module is required. <figref idref="f0007">Figures 5a</figref> and <figref idref="f0008">5b</figref> show such an attachment of a module <b>50</b> to an outlet <b>42</b>, wherein glue is applied to a specific area <b>51</b> (marked as shaded) of the module <b>50</b> and / or to the opposing surface <b>52</b> of outlet <b>42</b>. In most cases, such attachment is permanent.
0044Alternatively, releasable mechanical attachment can be achieved by using so called "hook and loop" fasteners, such as VELCRO, or any other releasably joined surfaces. In this approach mating Velcro strips are attached to both the existing outlet and the module (e.g. by means of adhesives) on opposing and contacting surfaces, such that mechanical attachment is formed by juxtaposing the mating strips. The module can be separated from the outlet by applying enough force to release the VELCRO fastener.
0045As described above, the present invention uses two approaches for mechanical attachment, namely permanent and detachable. In the permanent solution, such as the gluing described above, the module is attached to the existing outlet and cannot be easily detached therefrom, thus creating a joined outlet/module unit. In the detachable approach, where, for example, suction or VELCRO are used, the module may be detached and separated from the outlet, allowing for returning to the pre-attachment state. The separation of the module from the outlet may be easy and bare handed (such as in the case of Velcro, for example), or use standard or specific tools (e.g. screwdriver).
0046The electrical connection between the existing outlet and the module is made via utility connectors, such as RJ-11 jacks for telephony as described above. In one more embodiments of the present invention, the connector also aids and enhances the mechanical attachment. As described above, the RJ-11 plug is fixed and attached to the module, thus providing the additional mechanical support. However, some connectors are not designed for such mechanical stress and may be harmed in such usage or affect the reliability of the electrical connection. In one or more embodiments of the present invention, the connector is used solely for the electrical connection. In such a case, the mating connector in the module is not fixed to the enclosure but rather connects via a cable ('dongle' approach). An exemplary configuration is shown in <figref idref="f0009">Figure 6</figref> illustrating a RJ-11 plug <b>31</b> connected to the module <b>60</b> (a portion of whose rear part is shown) via a short cable <b>61</b>. Mounting of a module on an existing outlet typically requires connecting the connector in the module to the mating connector in the outlet, followed by the mechanical attachment. In the case wherein .the attachment is not permanent, the module connector should be unplugged as part of the separation process.
Side clamping.
0047In accordance with other embodiments of the invention, side clamping is employed whereby the module is attached by means of modules parts pressed against the sides of the existing outlets. Such a configuration is illustrated in <figref idref="f0010">Figures 7a</figref> and <figref idref="f0011">7b</figref>. A module <b>70</b> shown is based on basic module <b>30</b> described above, further having movable side bars <b>71a</b> and <b>71b</b> that may be splayed apart and released so as to engage respective edges <b>72a</b> and <b>72b</b> of the outlet <b>42</b>. The recesses <b>71a</b> and <b>71b</b> may be resiliently mounted on the outer surface of the outlet so as to be capable of mutual outward separation. Alternatively, the edges <b>72a</b> and <b>72b</b> of the outlet <b>42</b> may be provided with an outwardly protruding ridge that engages the respective recesses <b>71a</b> and <b>71b</b>, in which case it is sufficient to rely on the elasticity of the outlet casing to ensure a snap fit between the recesses and the respective ridges. Springs may be used to provide the pressing forces. The module <b>70</b> attached to outlet <b>42</b> is shown in <figref idref="f0011">Figure 7b</figref>. Although in the figures, the peripheral recesses <b>71a</b> and <b>71b</b> are mounted on side edges of the outlet, they can equal well be mounted on upper and lower edges thereof.
0048<figref idref="f0012">Figure 8a</figref> shows a module <b>80</b> having a pair of eccentric levers <b>81a</b> and <b>81b,</b> constituting an eccentric level mechanism. As shown in the detailed view <b>82</b> in <figref idref="f0013">Figure 8b</figref>, the lever <b>81b</b> may swivel about axis <b>83.</b> Upon attaching the module <b>80</b> to the outlet <b>42</b> as shown in <figref idref="f0014">Figure 8c</figref> and pushing the levers in a first direction (e.g. upward), the levers <b>81a</b> and <b>81b</b> are pressed against respective sides surfaces <b>72a</b> and <b>72b</b> of the outlet <b>42</b> thus 'locking' the module <b>80</b> to the outlet <b>42.</b> Rotating the levers <b>81</b> in a second, opposite direction (e.g. downward), unlocks the module <b>80</b> from the outlet <b>42.</b>
0049While the invention has been described with regard to a module for installing onto a telephone outlet, it will be appreciated that the invention equally applies to other outlets, such as power and CATV outlets. An example of a module <b>90</b> using side clamping as described above is shown in <figref idref="f0015">Figure 9a</figref>. Similar to module <b>70</b> described above, the module <b>90</b> comprises a data connector <b>34</b>, indicators <b>33a</b> and <b>33b</b>, as well as movable side bars <b>71a</b> and <b>71b</b>. Instead of the telephone jacks <b>32a</b> and <b>32b</b> of module <b>70</b>, an RF connector <b>91</b> is employed. The connector <b>91</b> may be F-Type connector common in CATV system in North America, BNC type or any other. As shown in <figref idref="f0016">Figure 9b</figref>, the module <b>90</b> is attached to a CATV outlet <b>92</b> having RF connector <b>99</b>, which may be F-Type jack common in CATV system in North-America, BNC type or any other coaxial cable connector. In a similar manner as described above, the module <b>90</b> is attached and secured to the outlet <b>92</b> via peripheral recesses <b>71a</b> and <b>71b</b> that engage respective side edges <b>72a</b> and <b>72b</b> of the outlet <b>92</b>.
0050<figref idref="f0017">Figure 9c</figref> shows a snap-on module <b>90</b> having an RF plug <b>94</b> that is flexibly mounted via a short cable <b>95</b>. However, the plug may equally well be rigidly mounted to the outlet.
0051An example of a module for use with power outlets is shown as module <b>100</b> in <figref idref="f0018">Figure 10a</figref>. Serving in conjunction with power delivery wiring the module comprises a power receptacle <b>101</b> shown to support two prong appliances common in North America. Other features are similar to the modules described above. The module <b>100</b> can snap onto the power outlet <b>102</b>, as shown in <figref idref="f0019">figure 10b</figref>, connecting to an outlet power receptacle <b>93</b> and mechanically attached to its side surfaces <b>72a</b> and <b>72b</b> as explained above. While a 2-prong outlet and plug are described, it will be appreciated that the same applies for 3-prong outlets and plugs.
Snap locking.
0052In one or more embodiments according to present invention the module is attached to the existing outlet by inserting a tab between the outlet faceplate and the wall. Such a module <b>110</b> is shown in <figref idref="f0020">Figure 11a</figref>. The module <b>110</b> is based on the module <b>30</b>, wherein two swing latches <b>111a</b> (shown in <figref idref="f0023">Figure 11d</figref>) and <b>111b</b> are added, as shown in <figref idref="f0021">Figure 11b</figref>. Upon attachment of the module <b>110</b> to outlet <b>42</b>, a snap lock action is achieved by swinging the latches <b>111a</b> and <b>111b</b>, such that the latches are forced between the outlet <b>42</b> and a wall on which the outlet <b>42</b> is mounted. Such action attaches the module <b>110</b> to the outlet <b>42</b> as shown in <figref idref="f0022">Figure 11c</figref>. <figref idref="f0023">Figure 11d</figref> shows a detailed view <b>112</b> of the latch <b>111a.</b> In this example, no simple releasing mechanism of latches <b>111</b> is described.
Band
/
strap securing.
0053While the invention has been described with regard to the attachment means being an integral part of the module, it will be appreciated that the invention equally applies to the cases wherein the mechanical attachment means are decoupled from both the existing outlet and the module. Such an approach is now demonstrated herein by way of non-limiting example with regard to the use of a securing strap or band.
0054A U-shaped securing band or strap <b>120</b> is illustrated in <figref idref="f0024">Figures 12a</figref> and <figref idref="f0025">12b</figref>. The band <b>120</b> is stiff yet provides some degree of elasticity, and comprises two rigid abutments <b>121a</b> and <b>121b</b>. The band <b>120</b> is used to urge the module <b>30</b> against the outlet <b>42,</b> wherein the abutments <b>121a</b> and <b>121b</b> abut a rear surface of the outlet <b>42,</b> thus securing the mechanical attachment.
0055<figref idref="f0026">Figure 13a</figref> shows a similar band <b>130</b> whose abutments <b>121a</b> and <b>121b</b> are articulated to respective levers <b>131a</b> and <b>131b</b>. A module <b>30</b> attached to an outlet <b>42</b> using the band <b>130</b> is illustrated in <figref idref="f0027">Figure 13b</figref> and in <figref idref="f0028">Figure 13c</figref>. The levers <b>131a</b> and <b>131b</b> may be used to latch and secure the surfaces <b>121a</b> and <b>121b</b> in place, or alternatively may be used for releasing their pressure, thus enabling easy and quick separation of the module <b>30</b> from the outlet <b>42</b>.
0056While the invention has been described with regard to a limited number of attachment techniques such as surface attachment, side clamping, snap locking and strap securing, it will be appreciated that the invention applies equally to other methods and means supporting mechanical attachment and electrical connection of a module to an outlet Furthermore, it will be appreciated that any combination of the above methods or any combination of any one described method with another method falls within the scope of the present invention.
Fastening Screws
0057Common existing outlets are comprised of two parts: a plastic faceplate mounted at the front of the outlet, and the outlet body which is secured to the wall. In most cases, the faceplate is fastened to the outlet body by one or two screws. In one or more embodiments, screws are used for securing the module to the outlet. If desired, the same screws may be used for securing the faceplate to the outlet body. A faceplate <b>42</b> of an outlet with screws removed is shown in <figref idref="f0029">Figure 14a</figref>, illustrating threaded apertures 141a and <b>141b.</b> The Figure also shows a module <b>145,</b> having two thru-holes <b>142a</b> and <b>142b.</b> Screws <b>143a</b> and <b>143b</b> are inserted through the respective thru-holes to the module <b>145</b> so as to threadably engage the threaded apertures <b>141a</b> and <b>141b</b> in the outlet <b>42</b> thereby securing the module <b>145</b> to the outlet body. The screws <b>143</b> are longer than the ones used just for securing the outlet faceplate alone.
0058Upon tightening the screws <b>143</b> the module <b>145</b> is mechanically attached to the outlet <b>42</b> as shown in <figref idref="f0030">Figure 14b</figref>. Unscrewing the screws <b>143</b> allows the separation of the module <b>145</b> from the outlet <b>42</b>. It should be noted that in this embodiment, faceplate <b>42</b> of the outlet may be eliminated upon attaching the module to the outlet.
Adapters.
0059The invention has been described above with respect to the case wherein the module directly mounts on the existing outlet, without using any intermediary device (except adhesives). However, in many cases it may be beneficial to use a discrete mechanical adapter between the outlet and the module. When using such mechanical adapter, the adapter is to be attached to both the existing outlet and to the module. One advantage of using such adapter is the capability of mounting the same module to various outlet configurations, using different adapters for each outlet type. Another advantage involves the capability to easily exchange modules types, while obviating the need to replace the mechanical adapter.
0060In the configuration of using a mechanical adapter, two mechanical attachments are involved. One is the attachment of the adapter to the existing outlet, and the other involves attaching the module to the mechanical adapter. The above mechanical attachments are of course in addition to the need for the electrical connection of the module to the outlet. According to the invention, the two attachments, namely the outlet /adapter and the adapter / module are fully decoupled and independent. For example, each attachment may be permanent or removable. Furthermore, in some applications the outlet /adapter attachment will be executed first, while other applications may call for the adapter / module attachment to be performed first.
0061Each or both of the outlet / adapter and adapter / module attachments may use any of the above described attachment methods, such as side clamping, surface attachment, snap locking and strap / band securing, or any other attachment methods and means. For the sake of simplicity, an example describing only adapter / module attachments will now be described.
Latch / Snap-fit adapter.
0062An exemplary latch / snap-fit adapter <b>150</b> according to the present invention is illustrated in <figref idref="f0031">Figure 15a</figref>. In this example, the mechanical adapter <b>150</b> is attached to the outlet using surface attaching, such as adhesives. An opening <b>151</b> in the adapter <b>150</b> allows access to the existing outlet jack. Two snap-fit connectors are provided each comprising a flexible tab having a respective outwardly projecting lug <b>152a</b> and <b>152b</b> on outermost faces thereof for attaching to the snap-on module. The adapter <b>150</b> is first attached (e.g. glued) to the existing outlet <b>42</b> as shown in <figref idref="f0032">Figure 15b</figref>. The adapter <b>150</b> is used in conjunction with module <b>155</b> shown in <figref idref="f0032">Figure 15b</figref>. The module <b>155</b> has apertures, of which only one <b>156a</b> is shown, in opposite surfaces and being dimensioned for engaging corresponding ones of the lugs <b>152a</b> and <b>152b</b> whereby the module <b>155</b> is snap-fitted on to the outlet <b>42</b> as shown in <figref idref="f0033">Figure 15c</figref>.
0063While the above attachment is described regarding first attaching the adapter <b>150</b> to the outlet <b>42</b>, in a similar way the first action may be attaching the adapter <b>150</b> to the module <b>155</b> as shown in <figref idref="f0034">Figure 15d</figref>. In such case, the combined module <b>155</b> / adapter <b>150</b> is then attached (e.g. glued) to the existing outlet <b>42</b>.
0064It is apparent that such module <b>155</b> / adapter <b>150</b> attachment may be permanent or separable. In the latter case, pushing or depressing the lugs <b>152</b> will release the module <b>155</b> from the combined outlet <b>42</b> / adapter <b>150</b> assembly.
0065While the above configuration has been illustrated showing vertically located slots, it will be apparent that horizontal snap-fit connectors may equally well be used, as are shown in the adapter <b>160</b> depicted in <figref idref="f0035 f0036 f0037 f0038">Figures 16a to 16d</figref>.
0066While adapters <b>150</b> and <b>160</b> above have been described as each having two support attachment points, it will be appreciated that this is not intended to be limiting and more than two connectors may be used. Thus, <figref idref="f0039">Figure 17a</figref> shows an exemplary adapter <b>170</b> supporting four snap-fit connectors, of which only two <b>171a</b> and <b>171b</b> are shown, attached to an outlet <b>42</b>. Two snap-fit connectors <b>171a</b> and <b>171b</b> are located on the upper surface and two snap-fit connectors (not shown) are located on the lower surface, thereby providing four supporting points in total. A module <b>175</b> shown in <figref idref="f0040">Figure 17b</figref> comprises respective apertures of which only two <b>176a</b> and <b>176b</b> are shown, for engaging the snap-fit connectors in the adapter, resulting in a combined module <b>175</b> / adapter <b>170</b> / outlet <b>42</b> as shown in exploded view in <figref idref="f0040">Figure 17b</figref>, and pictorially in <figref idref="f0041">Figures 17c</figref> and <figref idref="f0042">17d</figref>. In one or more embodiments according to the present invention, two of the snap-fit connectors (e.g. the two lower ones not shown in the Figures) may be used as axis and guiding means, aiding the locking of the other pair <b>171a</b> and <b>171b.</b>
Bayonet (rotating) latch.
0067In one or more embodiments according to the present invention, a rotating latch mechanism is used, as shown in <figref idref="f0043">Figure 18a</figref>. The figure illustrates an adapter <b>180</b> comprising a receptacle / socket <b>181.</b> The adapter <b>180</b> is releasably secured to a module <b>185</b> using a bayonet latch comprising a rotating plug <b>186</b> having two positions, namely 'Open' and 'Locked' for bayonet fitting to the socket <b>181.</b> As shown in <figref idref="f0044">Figure 18b</figref>, in the "'Open" position the rotating plug <b>186</b> can freely move in and out of the receptacle /socket <b>181.</b> The adapter <b>180</b> is shown in <figref idref="f0045">Figure 18c</figref> attached to outlet <b>42.</b> Module <b>185</b> spaced from outlet <b>42</b> prior to mounting is shown in <figref idref="f0046">Figure 18d</figref>. Upon attaching the module <b>185</b> to the combined outlet <b>42</b> / adapter <b>180</b> assembly, the rotating plug <b>186</b> is inserted into socket <b>181</b> and twisted from the front (as shown in <figref idref="f0045">Figures 18c</figref> and <figref idref="f0048">18f</figref>) to the 'Locked' position using a screwdriver, a coin or the like, thereby bayonet locking of the plug <b>186</b> to receptacle <b>181</b>, and attaching the module <b>185</b> to outlet <b>42.</b> The locked configuration is shown in <figref idref="f0049">Figure 18g</figref>. Rotation the plug <b>186</b> back to the 'Open' position will release the module <b>186</b> from the adapter <b>180</b> / outlet <b>42</b> assembly. While a single plug / receptacle pair has been described, it will be appreciated that two or more such bayonet latches may be used, resulting in added stability and security.
Magnetic adapter.
0068While the invention has been described with regard to using mechanical structures, forces, moments and mechanisms, it will be appreciated that the invention equally applies to any other attaching techniques such as using magnetic forces. An example of such embodiment is shown in <figref idref="f0050">Figure 19a</figref>. The module <b>190</b> comprises two magnets <b>191a</b> and <b>191b.</b> As illustrated in <figref idref="f0051">Figure 19b</figref>, magnetic or magnetizable metal discs <b>192a</b> and <b>192b,</b> serving as the adapter, are attached (e.g. glued) to the outlet <b>42,</b> in registration with the respective module <b>190</b> surfaces <b>191.</b> The magnets/discs <b>191a</b> and <b>191b</b> are magnetically attached to the respective metal discs <b>192a</b> and <b>192b,</b> thus attaching the module <b>190</b> to the outlet <b>42.</b> It will be appreciated that both <b>191</b> and <b>192</b> may be magnetic bodies having opposite polarities. Similarly, the module <b>190</b> may comprises metal discs <b>192</b> for mating with magnetic surfaces <b>191</b> on the outlet <b>42</b>.
0069While the invention has been described with regard to mechanical adapters being a discrete and stand alone device, it will be appreciated that the invention applies equally to the cases wherein the adapter is an integral with the outlet, or to the cases wherein the adapter is an integral with the module.
Home Network based module.
0070A general functional schematic block diagram of a module <b>250</b> typically used in home network environment is shown in <figref idref="f0052">Figure 20</figref>. The module <b>250</b> facilitates a data network over in-house wiring simultaneously with the basic service, which the wiring was originally installed to support. Non-limiting examples are a telephone outlet connected to the telephone wiring to support telephone service, a power outlet connected to the power wiring to support AC power distribution and a CATV outlet connected to the CATV cabling to support CATV distribution. The module connects to the outlet via a connector <b>251</b>. Since in most cases the module <b>250</b> is required to retain the basic service (being telephony, AC power or CATV) added to data networking functionality, the module <b>250</b> embeds a service connector <b>253</b> used to provide the original service. A data/service splitter/combiner <b>252</b> is used to separate (and combine) the basic service signal carried over the wiring from the data signal. For example, in the case wherein the data and the service each use signals of a different frequency spectrum over the wiring (FDM - Frequency Division Multiplexing), the splitter/combiner <b>252</b> will use a first filter to isolate the service signal spectrum and to couple it to service connector <b>253</b> as well as a second filter to isolate the data signal spectrum and to feed it to a medium modem <b>254</b>. Similarly, the service and data signals are combined by the splitter / combiner <b>252</b> and fed to the wiring via connector <b>251</b>. In some implementations, the technology enables a direct connection of the medium modem <b>254</b> and the service connector <b>253</b>, thus obviating the need for the data/service splitter/combiner <b>252</b>, and both the medium modem <b>254</b> and the service connector <b>253</b> are directly connected to the wiring connector <b>251</b>. Medium modem <b>254</b> functions to transmit and receive data over the wiring. In the case of a power outlet, the medium modem <b>254</b> enables carrying data over the powerlines. Similarly, the medium modem <b>254</b> enables carrying data over the telephone wiring in the case of telephone outlet and over the CATV cables in the case of CATV outlet In most cases, the modem <b>254</b>, working together with the splitter / combiner <b>252</b>, is optimized neither to interfere with the basic service signal carried over the wiring nor to be interfered by it.
0071The module <b>250</b> provides access to the data carried over the in-house wiring via a module integrated interface, comprising data connector <b>258</b> and interface adapter <b>256</b>. Interface adapter <b>256</b> functions to include all circuitry required in order to support the required interface when connected to the data network, while the actual physical connection uses data connector <b>258</b>, representing data connector <b>34</b> described above. In general, any serial or parallel data interface may be used. However, in most cases, the data <b>interface</b> supported as well as the connector <b>258</b> will adhere to a common standard data interface. Examples of such digital data interfaces are IEEE802.3 10/100/1000BaseT (commonly using RJ-45 connector type <b>34</b> shown above), USB (Universal Serial Bus), IEEE1284, EIA/TIA-232, IEEE1394 as well as others. Furthermore, the interface supported by the module <b>250</b> through connector <b>258</b> may also be of analog type rather than the digital type described. Some examples describing outlet built-in interfaces are: <ol id="ol0001" compact="compact"><li><b>1. Analog video interface.</b> The outlet may be used to input analog video, output analog video or both. It should be noted that this video is to be distinguished from the CATV video signal carries as basic service, but rather involves a video signal carried in digital form as part of the data network formed. An outlet supporting an analog video interface is described in <patcit id="pcit0016" dnum="WO03039150A"><text>WO 03/039150</text></patcit> entitled <i>'Outlet with analog signal adapter, a method for use thereof and a network using said outlet'</i> assigned to the present assignee. In such an outlet, the interface adapter <b>256</b> comprises Analog to Digital (A/D) or Digital to Analog (D/A) converters as appropriate.</li><li><b>2. Analog voice (audio) interface.</b> The outlet may be used to input analog voice, output analog voice or both. It should be noted that this voice is to be distinguished from the telephony signal carried as basic service, but rather involves a voice signal carried in digital form as part of the data network formed. In such an outlet, the interface adapter <b>256</b> comprises Analog to Digital (A/D) or Digital to Analog (D/A) converters as appropriate.</li><li><b>3. Telephone interface.</b> The outlet may be used to connect to a telephone device. It should be noted that this telephone signal is to be distinguished from the telephone signal carried as basic service, but rather involves a telephone signal carried in digital form as part of the data network formed. An outlet supporting telephone interface is described in <patcit id="pcit0017" dnum="WO03005691A"><text>WO 03/005691</text></patcit> entitled <i>'Telephone outlet with packet telephony adapter, and a network using same'</i> assigned to the present assignee. In such an outlet, the interface adapter <b>256</b> comprises Analog to Digital (A/D) or Digital to Analog (D/A) converters as appropriate.</li></ol>
0072In the basic scenario, interface adapter <b>256</b> can be directly connected to the medium modem <b>254,</b> allowing signal flow from a unit connected to the outlet via connector <b>258</b> and interface adapter <b>256</b> to the wiring via the wiring connector <b>251</b> through the medium modem <b>254</b> and the splitter/combiner <b>252.</b> In such cases, hub <b>255</b> and management <b>257</b> are not required.
0073In a managed data network environment, it would be beneficial to include part or all of the network management functionalities into the module <b>250.</b> For example, addressing means may be integrated into the outlet in order to allow the outlet to be remotely referenced. In yet another example, QoS (Quality of Service) tools are embedded into the outlet for measuring the service. Outlet integrated network management functionalities may comprise or support: <ol id="ol0002" compact="compact"><li><b>1. Performance management.</b> Measure and track network variables such as throughput, response time and line utilization.</li><li><b>2. Configuration management.</b> Monitor and change configuration information to track the affects of software and hardware elements.</li><li><b>3. Accounting management.</b> Measure utilization so that use of network resources can be tracked and regulated.</li><li><b>4. Fault management</b>. Detect, log and notify users of problems relating to the network running effectively.</li><li><b>5. Security management.</b> Control access to network resources.</li></ol>
0074The network management functionalities are supported by the optional management / processing unit <b>257.</b> Management functionalities may also include local - on outlet - visual indicators, such as indicators <b>33a</b> and <b>33b</b> described above. The management /processing unit <b>257</b> is coupled to all relevant functions in the outlet such as medium modem <b>254</b>, hub <b>255</b> and interface adapter <b>256.</b>
0075An optional multi-port unit (hub) <b>255</b>, identical to hub <b>11</b> described above, may be used in order to mediate the multiple data streams in the outlet. Basically, the hub <b>255</b> mediates between the data stream associated with the external data device connected via connector <b>258</b> and interface adapter <b>256</b> and the network formed over the wiring via medium modem <b>254</b>.
0076A telephone module <b>260</b>, representing for example module <b>30</b> above, is shown in <figref idref="f0053">Figure 21</figref> as a non-limiting example of module <b>250.</b> The module <b>260</b> is based on HomePNA technology known in the art for carrying data over active telephone wiring. Connector <b>261</b>, associated with connector <b>251</b> of module <b>250</b>, is used to connect to the in-house telephone wiring. Such connector <b>261</b> represents the connector <b>31</b> described above. Splitter / combiner <b>252</b> of general module <b>250</b> are implemented by a set of Low Pass Filter (LPF) <b>262</b> and High Pass Filter (HPF) <b>265</b>. Similarly, the medium modem <b>254</b> of general module <b>250</b> is implemented by PNC (phonelines carrier) modem <b>264</b>. Connector <b>263</b> is a standard telephone connector (e.g. RJ-11 in North America) representing general service connector <b>253</b> of general module <b>250</b>. Such connector <b>263</b> represents the connector <b>32a</b> described above.
0077Similarly, an example of a powerline module <b>270</b> not forming part of the present invention<b>,</b> representing for example module <b>100</b> above, is shown in <figref idref="f0054">Figure 22</figref>. The module comprises power connector <b>273</b> retaining the original AC power device, wiring connector <b>271</b> to connect to the AC power wiring via power outlet such as <b>102</b>, and PLC modem <b>274.</b> Such connector <b>273</b> represents connector <b>101</b> described above. In this example, no separation is required between the wiring, the PLC modem <b>274</b> and the power connection <b>273</b>, hence splitter/combiner <b>252</b> of the general module <b>250</b> is not required. Some PLC modem <b>274</b> implementations may still require such separation device.
0078Another example of the general module <b>250</b> is the CATV module <b>280</b>, representing for example module <b>90</b> above, shown in <figref idref="f0055">Figure 23</figref>. Connector <b>281</b> provides the connection to the coaxial cable, and the CATV service is retained via RF connector <b>283</b>. Such connector <b>283</b> represents connector <b>91</b> described above. A coax modem <b>284</b> is used as the medium modem. In most cases the data network uses one of the video channels carried over the coaxial cable, the splitter/combiner <b>252</b> is replaced by Band Pass Filter (BPF) <b>282</b>, and the connector <b>283</b> is directly connected to the wiring connector <b>281.</b> Such connector <b>281</b> represents the connector <b>94</b> described above.
LAN Environment.
0079While the invention has been described with regard to networks formed over wiring used for utility services (e.g. telephone, CATV and power), it will be appreciated that the invention can be equally applied to outlets used in networks using dedicated wiring. In such a scenario, the basic service is a single data network interface. However, it may be required to provide additional interfaces to an outlet, beyond the basic service of single data connectivity interface. For example, it may be used to provide multiple data interfaces wherein the wiring supports such single data connection. An example for such an outlet is the Network Jack<sup>™</sup> product family manufactured by 3Com™ of Santa-Clara, California, U.S.A. In addition, such outlets are described in <patcit id="pcit0018" dnum="US6108331A"><text>U.S. Patent 6,108,331 to Thompson</text></patcit> entitled <i>'Single Medium Wiring Scheme for Multiple Signal Distribution in Building and Access Port Therefor'</i> as well as U.S. Patent Application <patcit id="pcit0019" dnum="US20030112965A"><text>US 2003/0112965 Published June 19, 2003 to McNamara et al.</text></patcit> entitled '<i>Active Wall Outlet</i>'<i>.</i>
0080A non-limiting functional block diagram of such a module <b>290</b> is shown in <figref idref="f0056">Figure 24</figref>. While the general structure is similar to general module <b>250</b>, some adaptations are required to the specific application. The data / service splitter / combiner <b>252</b> is not required since only a single type of signal is carried over the wiring. A simple transceiver <b>293</b> is used to transmit and receive signals over the network wiring. Transceiver <b>293a</b> is used to interface the wiring via connector <b>291</b>. The 'basic service' of data port is provided via data connector <b>292</b>, using transceiver <b>293b</b>. Both transceivers, as well as adapter <b>256</b> (connected to interface connector <b>258</b>) all share the data via hub <b>255</b>. The outlet may be managed by management / processing function <b>257</b>.
Other functionalities.
0081While the invention has been described with regard to active (power consuming) components (e.g. modem) used to provide access to the data signal carried over the wiring, it will be appreciated that the invention equally applies to a module using only passive components for providing such coupling. An example of such implementation is described with regard to a passive outlet is disclosed in <patcit id="pcit0020" dnum="WO0225920A"><text>WO 02/25920 to Binder</text></patcit> entitled <i>'Telephone communication system and method over local area network wiring'.</i> Such outlets are available as part of the etherSPLIT™ system from QLynk Communication Inc. of College Station, TX USA.
0082While the invention has been described with regard to digital interfaces, it will be appreciated that the invention equally applies to a module wherein the adapter 256 converts to analog signal interface, such as audio or video, as well as analog sensor or analog actuator. Active outlets comprising a built-in analog converter are described for example in <patcit id="pcit0021" dnum="WO03039150A"><text>WO 03/039150 to Binder published May 8, 2003</text></patcit> and entitled <i>'Outlet with Analog Signal Adapter, a Method for Use Thereof and a Network Using Said Outlet'</i>. An illustration of an exemplary module <b>288</b> not forming part of the invention with video interface is shown in <figref idref="f0057">Figure 25</figref>, based on module <b>100</b> described above. Data connector 34 comprised in module <b>100</b> of <figref idref="f0018">Figure 10a</figref> is substituted with video connector (F-Type, BNC or similar) <b>259</b> shown in <figref idref="f0057">Figure 25</figref>. The relevant adapter <b>256</b> will include analog to digital (or digital to analog or both) functions. It should be noted that connector <b>259</b> is part of the module <b>288</b> and relates to video (or any analog signal) carried in digital form over the network, and should be distinguished from connector <b>91</b> of module <b>90</b> of <figref idref="f0015 f0016 f0017">Figure 9</figref>, wherein the video is the basic service and thus carried in analog form over the network
0083While the invention has been described with regard to wired and connector-based module <b>288</b>, it will be appreciated that the invention equally applies to an outlet wherein a data unit uses non-wired interface, such as audio, light (e.g. infrared) and radio frequency (commonly referred to as wireless). Such outlet is described in <patcit id="pcit0022" dnum="WO0180543A"><text>WO 01/80543 published October 25, 2001 to Binder</text></patcit>, entitled <i>'Network Combining Wired and Non-Wired Segments'</i>. In such a case, the connector <b>258</b> will be replaced substituted with a non-wired transceiver, such as a light emitter / receiver or antenna for RF. Alternatively, the non-wired interface is provided in addition to the wired interface. A pictorial view of the latter is module <b>268</b> with wireless interface is shown in <figref idref="f0058">Figure 26</figref>, based on module <b>145</b> shown in <figref idref="f0030">Figure 14b</figref> above. In addition to the data connector <b>34</b> in module <b>145</b> of <figref idref="f0030">Figure 14b</figref>, an antenna <b>269</b> is shown in <figref idref="f0058">Figure 26</figref>, as an example to non-wired interface.
0084While the invention has been described with regard to outlets having a single network interface (e.g. single connector <b>258</b>), it will be appreciated that the invention equally applies to the case wherein multiple network interfaces are supported. Furthermore, a mix of interface types may be employed, such as wired digital, wired analog and non-wired interfaces all in the same outlet. Similarly, while the invention has been described with regard to outlets having single basic service connection, such as telephone connector <b>263,</b> power connector <b>273,</b> CATV connector <b>283</b> or data network connector <b>292,</b> it will be appreciated that the invention equally applies to the case wherein multiple such connections are provided.
0085While the invention has been described with regard to outlets and networks based on conductive media such as wires and cables, it will be appreciated that the invention equally applies to the case wherein the network medium is non-conductive, such as fiber-optical cabling. In such a case, transceiver <b>293a</b> of module <b>290</b> should be substituted by a fiber optic transceiver, and similarly wiring connector <b>291</b> should be replaced by a fiber optic connector. Active outlets supporting data interfaces and based on fiber optic cabling are described in U.S. Patent Application <patcit id="pcit0023" dnum="US20020146207A"><text>US 2002/0146207 published October, 10 2002 to Chu</text></patcit>, entitled '<i>Fiber Converter Faceplate Outlet</i>'<i>,</i> as well as in <patcit id="pcit0024" dnum="US6108331A"><text>U.S. Patent 6,108,331 to Thompson</text></patcit> entitled <i>'Single Medium Wiring Scheme for Multiple Signal Distribution in Building and Access Port Therefor'.</i> As such, the term 'wiring' in this application should be interpreted to include networks based on non-conductive medium such as fiber-optics cabling.
Module Powering.
0086In one or more of the embodiments according to the present invention, the module includes active components (such as medium modem <b>254</b>), and as such needs to be powered. Three non-limiting powering schemes are now described including local feeding, power over wiring and via the interface module.
Local feeding.
0087In this implementation the module is connected to an external power source for feeding its active components. A pictorial view of such an approach is shown in <figref idref="f0059">Figure 27</figref>, not forming part of the present invention illustrating a module <b>279</b> according to any of the above embodiments. A common small AC/DC converter <b>278</b> is used (connectable to power socket <b>93</b> in distinct power outlet <b>102</b>), connected to the module via plug <b>296</b>.
0088A power adapter may be used in the module, for adapting the external power to the internal needs. Such adapter may include voltage conversion (such as DC to DC converter) in order to adapt to specific voltages required, protection circuits (such as fuse or current limiting), regulation and noise filtration, as well as other functionality as known in the art. In addition, such an adapter may comprise the functionality of an external AC/DC converter <b>278,</b> allowing the module to be directly connected to the mains obviating the need for external converter <b>278.</b> Schematic block diagram of such a module <b>295,</b> comprising such power adapter function <b>297</b> is shown schematically in <figref idref="f0060">Figure 28</figref>. The power adapter is fed from an external source via connector <b>296</b>, and outputs the required-DC power to all power-fed components in the module.
Power over wiring.
0089In one or more embodiments not forming part of the present invention the module is fed by power carried over the wiring and via the outlet to which the module is connected. The power may be carried over separated conductors. In this case, the same wiring connector <b>251</b> may be used to connect to the power carrying conductors using separated pins. Alternatively, additional power dedicated connector may be used.
0090In one or more preferred embodiments, the power is carried simultaneously over the wiring carrying the data network signals and / or the basic service signal. Such a module <b>285</b> is shown schematically in <figref idref="f0061">Figure 29</figref>. The power splitter function <b>287</b> serves to extract the power carried over the wiring, and feed it to the power adapter <b>286,</b> rather than the adapter <b>297</b> being externally fed. In most cases, the power splitter <b>287</b> operation should not interfere with the data and basic service also carried over the same wiring (e.g. loading effects and impedance matching).
0091The implementation of such a mechanism is trivial wherein the basic service is AC power as described above with respect to module <b>270</b> shown in <figref idref="f0054">Figure 22</figref>. The power splitter <b>287</b> comprises a simple filter and the power adapter <b>286</b> comprises a standard AC/DC converter (similar to the external unit <b>278</b> described above).
0092Recent techniques developed allow for carrying simultaneously power and basic service (and data) over the same wiring infrastructure. <patcit id="pcit0025" dnum="US20020003873A"><text>U.S. patent publication 20020003873 to Rabenko et al.</text></patcit> entitled: <i>'System and method for providing power over a home phone line network'</i> teaches carrying AC power over telephone wiring carrying both telephony and data, by using a part of the spectrum not used by the other signals. Similarly, a recent technique known as Power over Ethernet (PoE) (a.k.a. Power over LAN) and standardized under IEEE802.3af, also explained in <patcit id="pcit0026" dnum="US6473609B"><text>US Patent 6,473,609 to Lehr et al.</text></patcit> entitled <i>'Structure Cabling System',</i> describes a method to carry power over LAN wiring, using the phantom mechanism. The above technologies, as well as others, may be used to provide power to any of the modules described above. The power splitter <b>287</b> is adapted in accordance with the way power is carried. For example, in the case of using different spectrum for the power signal, a filter should be used. In the case of phantom type of feeding, two transformers are required as known in the art.
Powering via connected appliance.
0093As explained above, several data interface standards also carry power over the interface. For example, in the case where the module is connected to USB host unit, the USB interface may feed the module.
0094While the invention has been described with regard to a single power source, it will be appreciated that the invention equally applies to the case wherein multiple power sources are used either for redundancy or load sharing.
Non-networking functionalities.
0095While the invention has been described with regard to adding networking related functionality to an existing outlet, it will be appreciated that the invention equally applies to any other functionality to be added to an existing outlet by mechanically attaching and electrically connecting thereto. In one or more embodiments, the added functionality involves functions commonly offered as part of outlets.
0096One example may be added connections. Some outlets provide a single jack, while others provide multiple connections. A module according to the present invention may provide additional connections to a single-connection existing outlet.
0097Such non-networking related functionalities may be provided alone, or added to the above networking related functionalities. In the latter case, a module comprises both functionalities into a single enclosure.
AC Power module.
0098An exemplary module <b>300</b> not forming part of the present invention is shown in <figref idref="f0062">Figure 30a</figref>, connectable to a power outlet <b>102</b> comprising single power socket <b>93</b>. The module <b>300</b> is mechanically attached to the outlet <b>93</b> using side clamping elements <b>71</b> as described above, and provides three power sockets <b>101a</b>, <b>101b</b> and <b>101c</b>, each electrically connected directly to the socket <b>93</b>. It will be appreciated that any other number of sockets may also be provided. Furthermore, the module may be used to convert from one type of socket to another (such as from US type to European type). In the latter case, the module may comprise the transformer required for voltage adaptation (e.g. from 110VAC to 240 VAC).
0099Some power outlets are available offering built-in switched power sockets. Other outlets are known to comprise a built-in dimmer for lighting applications. Similarly, such functionalities may be added to an existing outlet by means of a module according to the present invention. Module <b>301</b> shown in <figref idref="f0063">Figure 30b</figref> provides switch <b>304</b>, connected in series to socket <b>302</b> to switch its power. Additionally, dimmer button <b>305</b> is shown, controlling in-module dimmer circuitry, to work in conjunction with socket <b>303</b>. It will be appreciated that, if desired, only one of the additional functionalities (i.e. switching and dimming) need be provided. Likewise, more than two additional functionalities may be provided where space permits.
0100Other non-limiting examples of functionalities which may be available in power outlets and may be embedded in modules in order to allow adding such functionalities to existing outlets (in addition to switching and dimming) are: <ul id="ul0002" list-style="dash" compact="compact"><li>Fuses, and other safety means.</li><li>Lightning protection, and any other protection means for protecting the connected appliance.</li><li>Visual indicators.</li><li>Grounding means such as side wiring.</li><li>Fan speed control.</li><li>TEST and RESET buttons for testing and resetting fuses.</li><li>Electronic timer switching.</li><li>Sensors, such as infrared occupancy sensors.</li><li>Filters (e.g. for noise filtering).</li><li>Security related sensors (e.g. heat, flood).</li></ul>
Telephone module.
0101An exemplary module <b>310</b> according to the invention is shown in <figref idref="f0064">Figure 31</figref>, connectable to a telephone outlet <b>42</b> comprising single telephone jack <b>43</b>. The module <b>310</b> is mechanically attached to the outlet <b>93</b> using any of the described above methods, and provides four telephone jacks <b>311a</b>, <b>311b</b>, <b>311c</b> and <b>311d.</b> Each such jack may be connected directly to the jack <b>43</b>, allowing four telephone devices to be connected to the same telephone line. Alternatively, in the case wherein jack <b>43</b> supports two or more telephone connections (using different pins), the telephone jacks <b>311</b> may connect to different telephone lines (e.g. jacks <b>311a</b> and <b>311b</b> to line 1 and jacks <b>311c</b> and <b>311d</b> to line 2). Such a module is described in <patcit id="pcit0027" dnum="US6366671B"><text>US Patent 6,366,671 to Beavers</text></patcit>, entitled '<i>Multiple outlet telephone jack</i>'<i>.</i>
0102Some telephone outlets are available offering built-in micro-filters, known in the art for use in conjunction with ADSL and HomePNA. Similarly, such micro-filters may be added to an existing outlet by means of a module according to the present invention. Other non-limiting examples of functionalities which may be available in telephone outlets and may be embedded in modules in order to allow adding such functionalities to existing outlets (in addition to switching and dimming) are: <ul id="ul0003" list-style="dash" compact="compact"><li>Lightning protection, and any other protection means for protecting the connected telephone device.</li><li>Visual indicators.</li><li>Sensors, such as infrared occupancy sensors.</li><li>Fuses, and other safety means.</li><li>Filters (e.g. for noise filtering).</li></ul>
0103While the non-networking functionalities have been exampled above with regard to power and telephone outlets, it will be appreciated that the invention equally applies to any type of outlet, including LAN and CATV outlets. In the latter case, a RF splitter may be used within a module for providing multiple CATV connections.
Integrated appliances.
0104While the invention has been described with regard to adding available outlet functionality to an existing outlet, it will be appreciated that the invention equally applies to any other functionality to be added to an existing outlet by mechanically attaching and electrically coupling thereto. In particular, the functionality of a device or an appliance which is commonly connected to an outlet can now be integrated, in part or in full, into the module. In such configuration, the need to connect via cables the appliances to the outlet is obviated. In addition to the improved aesthetics, excess exposed cables are inconvenient and dangerous. A few integration examples are described herein.
0105Small AC/DC converters such as device <b>278</b> described above are known as means to connect appliances to AC power. Such converter <b>278</b> may be directly attached to a power outlet or connected thereto via a power cord.

0107Another example of a device connected to a power outlet not forming part of the invention is a charger, such as PDA (Personal Digital Assistant) or cellular phone chargers. Such chargers commonly comprise a charging circuit and a mechanical base for the charged device. In one or more embodiments according to the present invention, such charger functionality is integrated into the module. A front view of such a module <b>330</b>, based on module <b>100</b> described above, is shown in <figref idref="f0068">Figure 33a</figref>, and a rear view is shown in <figref idref="f0069">Figure 33b</figref>. Added to the functions of module <b>100</b>, module <b>330</b> comprises PDA charger functionality. In addition to the built-in charger the module <b>330</b> further comprises a receptacle <b>331</b> and connector <b>339</b>, for providing electrical connectivity and mechanical seating to the charged PDA. The module <b>330</b> connects electrically to an AC power outlet via the two prongs forming the AC plug <b>332</b>, and is attached thereto by any of the described above methods. A PDA <b>333</b> in a charged position (assuming the module <b>330</b> is attached to an AC power outlet) is shown in <figref idref="f0070">Figure 33c</figref>. While described above with regard to PDAs, it will be appreciated that any mobile device may substitute the PDA, such as receptacle <b>336</b> and cellular telephone <b>337</b> shown in conjunction with the respective module <b>335</b> in <figref idref="f0071">Figure 33d</figref>.
0108While modules <b>330</b> and <b>335</b> not forming part of the present invention above are described as supporting only power functionalities, it will be appreciated that data networking may also be added. For example, in the case wherein the AC power wiring also carries data signals (as described above), powered (or charged) devices (such as PDA <b>333</b> or cellular telephone <b>337</b>) may also access this data network signal, acting as active nodes in the network. In such case, the module comprises part or all of the data functionality described above.
0109While modules <b>321</b>, <b>330</b> and <b>335</b> not forming part of the present invention are described above with regard to power modules providing power to devices / appliances connected / attached thereto, it will be appreciated that such power feeding functionalities may be included in other outlets (e.g. telephone, CATV and LAN outlets). The module may be powered by any one of the described above module powering methods (or combination thereof). One such exemplary telephone module <b>338</b>, based on telephone outlet <b>279</b> described above, is shown in <figref idref="f0072">Figure 33e</figref>. The module <b>338</b> is locally fed for powering its circuits, as well as charging the PDA <b>333</b> via a mechanical receptacle <b>331</b>.
0110While the modules are described above primarily for supporting power functionalities, it will be appreciated that data networking may be the primary or sole functionality supported. In such case, the device connected (e.g. PDA <b>333</b> or cellular phone <b>337</b>) is coupled to the data signal carried over the wiring, acting as a node in the data network. The module comprises part or all of the data functionality described above, but in addition (or instead) to the data connector (e.g. connector <b>34</b>) connects to the respective device. Furthermore, in addition to the example of PDA <b>333</b> and cellular telephone <b>337</b>, it will be appreciated that any other device may be supported for powering, data or both. Non-limiting examples are handheld or mobile devices such as digital camera, digital music player, digital video player and web pads.
0111While the modules <b>330</b>, <b>335</b> and <b>338</b> not forming part of the present invention are described above as providing a docking function for holding either a PDA <b>333</b> or a cellular phone <b>337</b>, it will be appreciated that any other such mechanical base, docking unit or mechanical attachment means may be used. In the general case, the module according to one or more embodiments according to the present invention provides a mechanical means (e.g. receptacle <b>331</b>) for mechanically attaching devices thereto (e.g. PDA <b>333</b> and cellular phone <b>337</b>)<b>.</b> The mechanical attachment may use gravity to hold the appliance to the module, or alternatively use (solely or in addition to gravity) a latching mechanism to secure such attachment. Such mechanical means (to be distinguished from the mechanical means used for attaching the module to the outlet) may also support electrical connection (as shown for the base <b>331</b> above, also providing power connection). In other embodiments, the electrical connection uses a connector provided by the module. A clear advantage of such approach is the ability to hang appliances and devices on the wall, rather than occupying a commonly loaded desk space.
0112It should be noted that <patcit id="pcit0030" dnum="US6518724B"><text>US Patent 6,518,724 to Janik</text></patcit> entitled <i>'Wall switch device and power outlet device'</i> discloses a power wall switch comprising a cradle for PDA or cellular telephone, as well as built-in wireless functionality. However, the cradle functionality described by Janik is part of the outlet and is not provided as an add-on module. Furthermore, Janik describes only a power outlet and in particular a wall switch, and is silent about other types of outlets such as telephone, CATV and LAN outlets.
Integrated telephone appliances.
0113While the invention has been described with regard to integrating power consuming devices to a power module, it will be appreciated that the invention equally applies to integrating telephone-outlet connected devices to telephone modules.

Non-technical applications
not forming part of the present invention.
0116While the modules above are described with regard to technical functionalities, it will be appreciated that the invention may be implemented for non-technical applications such as improved aesthetics. In such applications, the module may be limited to the provision of a decorative design and not necessarily include electrical or mechanical functionality. Such a design may be suited to the householder's taste, and may for example be used to harmonize with other parts of the room. For example, a module according to the present invention may have a unique color, texture or decoration. Most available outlet faceplates are offered in a very limited number of colors and shapes, and such a module allows for a specific color, shape, texture, decoration or any other ornamental feature. Furthermore, in the case wherein there is a need to change the color, for example in the case of painting the walls, such change can be easily done with the module, obviating the need to replace part or all the existing outlet and obviating the need to interfere with the utility wiring.
0117In addition to decoration (e.g. color), the module may be shaped in an artistic manner. Examples of module shapes, structures and other ornamental designs are shown in <figref idref="f0073">Figures 34a</figref> and <figref idref="f0074">34b</figref>. Both figures illustrate power modules based on power module <b>100</b> described above, with the distinction of providing two data communication ports <b>34a</b> and <b>34b</b>, rather than the single data connector <b>34</b> comprised in power module <b>100</b>. A power module <b>341</b> is shown in <figref idref="f0073">Figure 34a</figref> attached to a power outlet <b>102</b>, and providing a power socket <b>101</b> and a visual indicator <b>33a</b>. The module <b>341</b> is shaped as a 'teddy-bear' face. Such structure, as well as any other animal theme shapes may fit into a child's room. Other themes may also be employed, such as a sports personality or musician, musical instrument and so on. Another artistic aspect is shown as oval shaped power module <b>342</b> in <figref idref="f0074">Figure <b>34b</b></figref>. The module <b>342</b> is shown as using snap locking attachment method based on tabs <b>111a</b> (not shown) and <b>111b</b> as described above.
Status indicators.
0118The module may comprise visual indicators <b>33a</b> and <b>33b</b> as described above for allowing the user to easily observe the module status. Such indicators may be LEDs (Light Emitting Diode) known in the art. The visual indicators may be used to indicate the following module status.
0119<b>Power</b>. The visual indicator may be used to indicate the existence of power in the module to power its internal active circuits. Various techniques have been described above for powering a module. Regardless of the power source to the module (as described above), such indication will ensure that indeed power reaches the module. Such indication is commonly marked as 'POWER' or 'ON'. The indicator can be coupled directly to the power signal feeding the module or alternatively coupled to the power supply output. In the latter case, the indicator is used to indicate both the power signal availability and the proper operation of the internal power supply. The latter case is demonstrated in <figref idref="f0075">Figure 35</figref>. The module <b>350</b> shown is based on module <b>285</b> described above. The module <b>350</b> comprises a LED <b>352</b> connected in series to a resistor <b>351</b>, required for current limiting. The LED <b>352</b> may serve in this configuration as indicator <b>33a</b>, for example. The LED <b>352</b> is connected to the output of power adapter <b>286</b>, hence the illumination of LED <b>352</b> indicates the proper operation of both the power adapter <b>286</b> and the power splitter <b>287</b>, as well as the existence of power feeding to the module <b>350</b>.
0120<b>Proper operation</b>. A visual indicator may also be used to indicate the proper operation of part or all of the electronic circuits integrated within the module. The electronic circuits within the module may support self-test or any other built-in diagnostics means, wherein the test results will be signaled by a visual indicator.
0121<b>Communication status</b>. In the case wherein the module comprises communication functionality, the module may indicate the availability and the status of the communication. In general, two communication links may be involved. One communication link refers to the availability of a data communication signal over the service wiring so as to indicate that modem <b>254</b> receives a valid communication signal. For example, in the case wherein two modules are installed in a home to allow communication between them, both will indicate the existence of a network over the service wiring. The other communication link involves the communication between a data unit connected to the module and the module. Such communication link may be established upon connecting an appropriate operative data unit to connector <b>258</b> (or <b>34</b>) of the module. Such status indication can be based on a 'Link Pulse' mechanism commonly used in Ethernet IEEE802.3 10/100BaseT based networks.
0122In addition to indicating the existence of operative data network, it is useful to have information about the performance of such a communication link. For example, the data rate (either effective or nominal) may be an important network parameter. In this case, the visual indicator will provide information about the network performance. Common 10/100BaseT Ethernet networks commonly employs two indicators to signal if the system works in the 10Mb/s or 100Mb/s modes. Any other visual indicators providing quantified information may be used, such as 'bar graph', number, multiple intensity levels and the like.
0123<b>Service monitoring.</b> The module may comprise a service monitoring means. In such a case, the visual indicator signals the availability and the status of a service signal. In the case of power module, not forming part of the present invention the availability of AC power (either 110 or 220VAC) will be sensed and indicated. In the case or telephone module, the indicator may reflect the existing or a telephone signal, the existing of 'OFF HOOK' state, ringing state and the like. Similarly, in the case of CATV module, the existence of the CATV signal may be indicated.
0124The above various states may be each represented by a single dedicated single-state indicator. However, in order to reduce complexity, known techniques are commonly used in order to combine signals. Such techniques may use different colors (of the same indicator), different intensity levels, variable duty-cycle and so forth. While visual indicators have been described, other indicating methods may be used such as audible tones (as stand alone or combined with visual).
