BACKGROUND OF THE INVENTION

This is a continuation-in-part of Application. Serial No. 09/384,961 filed August 27, . 1999, which is a continuation-in-part of Application Serial No. 09/062,093 filed April 17, 1998 and issued as U.S. Patent No. 5,969,968. 5 This invention relates to a remote ordering system for a restaurant drive-through lane.

The drive-through lanes in many restaurants have added a very beneficial feature for both the consumer and the proprietor. The drive-through allows the proprietor to remain open longer, while the restaurant is being cleaned for the next day. The drive-through also allows more efficient handling of customers with a reduction in staff count 10 The customer gets the benefit of staying in his or her vehicle while being serviced.

That is especially important to young families and to those with mobility problems, such as the aged or infirm.

Drive-through lanes have been around for quite some time. However, in the typical drive-through lane, a customer places an order by speaking into a microphone to an attendant. 15 The quality of these microphones is generally poor, resulting in miscommunication and errors in the order. By the time the customer finds out about the error, he has already waited in line. several minutes and must then wait several more minutes for a correct order to be filled. This results in the loss of customer goodwill: A problem with previous drive-through ordering systems that do not use a 2 0 microphone is that they require the customer to lean out of the vehicle to press a button on a menu or use a touch screen. This is awkward if not impossible for some people, such as very obese people. Also, this exposes the customer to rain, snow, etc., while the order is being placed. Generally speaking, there is no feedback as to the type, quantity, or total price of items ordered, and no capability to back up to correct an incorrectly entered item. 2 5 There is a need for a remote ordering system for a drive-through lane that addresses the above problems. Additionally, the system should provide a completely transportable, SUBSTITUTE SHEET (RULE 26) -2- hand-held remote device that can be assigned to customers who order frequently from the restaurant. Optimally, the device will have a customer identification which is transmitted with each order so that the restaurant can perform statistical analysis.

This application also relates to the use of a remote ordering device by wait staff 5 within a restaurant, to place orders, determine the status of orders, and allow the customer to pay the bill either by cash or credit card.

This application also relates to a generalized remote ordering device for customer use inside or outside a facility such as a restaurant, auto repair facility, retail store, grocery store, aiiport, or other service facility. The remote ordering device is a handheld device that allows 10 the customer to order products or services and access information.

There is a need for a hand held remote device on which a server in a restaurant enters each customer’s food and beverage order and then electronically sends the information directly to the kitchen without the server having to personally take the order. Each server could handle additional tables more efficiently, increasing their income, and saving the 15 restaurant staff salaries. The device can also have a credit card reader and signature “box” for the customer to complete the transaction at the table without having to wait in line at the cash register, or for the waitress to return with a credit slip to sign.

There is also a need for a generalized remote ordering device for customer use inside or outside a facility such as a restaurant, auto repair facility, retail store, grocery store, aiiport 20 or other service facility. The remote ordering device is a handheld device that allows the customer to order and pay for products or services and access information. -3-

SUMMARY OF THE INVENTION A generalized remote ordering apparatus for customer and employee use within a restaurant, auto repair facility, retail store, grocery store, airport, or other service facility, to place orders, determine the status of orders, access information, and allow the customer to 5 pay the hill either by cash or credit card, comprising: (a) an input device having a keypad, a battery, a first memory, a first processor, and a transmitter, and (b) an ordering station unconnected to said input device, said ordering station having a receiver tuned to said transmitter, a second processor adapted to decode information 10 received from said transmitter through said receiver and produce decoded information, a display adapted to display said decoded information, a second memory adapted to store item numbers and prices, and a communications link to a point-of-sale system. A principal object and advantage of the present invention is that it allows the customer to order items from a menu in a service facility without the necessity to speak to an 15 attendant. This results in more accurate orders.

Another object and advantage of the present invention is that the server can immediately send the orders to the kitchen without having to personally deliver them. They can spend more productive time serving patrons, handle more tables, and thus save labor expenses. 2 0 Another object and advantage of the present invention is that the orders are received faster, and the server can be notified of completed orders as soon as they are prepared in the kitchen. Food will not get cool waiting for servers to pick it up.

Another object and advantage of the present invention is that the individual orders will be automatically entered on the restaurant computer system, to be used in inventory 2 5 management, internal control, and marketing as desired. If the patron wishes to pay cash, or does not want to use a credit card, the order will be identified electronically at the check out register. If the restaurant wishes to have all patrons come to the check out register for -4-

control, the credit card slip and bill could already be completed saving time at the register. The tables that have prepaid could be identified at the check out register.

Another object and advantage ofthe present invention is that customers who are in a hurry can complete the credit card payment when the food is ordered, and not have to wait for 5 the server to give them the bill. They could leave when they are finished eating.

Another object and advantage of the present invention is that kitchen staff could always read the order, because no handwriting is involved.

Another object and advantage of the present invention is that the server ’s orders and tips could be constantly recorded automatically, even if charged at the table. 1 o Another object and advantage of the present invention is that each server could have their own ordering device, for easy identification in the kitchen or for personal notes in the jacket.

The above objects and advantages would be equally applicable for use by a customer at a service facility such as a restaurant, auto repair facility, retail store, grocery store, airport, 15 etc.'

The generalized remote ordering apparatus may also be used by the service facility to allow the customer to select a predetermined order and then enter it remotely. For example, the service facility may post an order code on a World Wide Web page that is correlated to a particular predetermined order. After accessing the web page, the customer enters the order 2 0 code into the input device and, while at the service facility, transmits the order code to the ordering station. The service facility may also require the customer to enter a credit card number before providing the order code. -5-

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The remote ordering system for a restaurant drive-through lane of the present 10 invention is generally designated in the Figures as referenced numeral 10.

The remote ordering system 10 comprises an input device 12 and a drive-up ordering station 14. The input device 12 is unconnected to the drive-up ordering station 14, and the input device is used from inside the vehicle V. Preferably, the input device 12 is hand-held and is transportable away from the drive-up ordering station 14. Multiple devices 12 maybe 15 used, with a separate device being assigned to each customer. The input device 12 is preferably used within direct line-of-sight of the drive-up ordering station 14. That is, it is not intended that the devices operate while greatly separated, as for example over a telephone network.

Preferably, the input device 12 has akeypad 16, battery 18, a first memory 20, a first 2 0 processor 22, and a transmitter 24. The first memory 20 and the first processor 22 may be discrete components, or they may both be in an Application Specific Integrated Circuit (ASIC) as seen in Fig. 3. A customer identification number may be stored in the first memory 20 for transmission to the drive-up ordering station with the order. -7-

<img img-format="tif" img-content="drawing" file="IL155156AD00025.tif" id="idf0005" />

The keypad 16 further preferably comprises a number of numeric keys 16a, an enter key 16b, a remove key 16c, a quantity add key 16d, a quantity subtract key 16e, and a start/finish key 16f, as seen in Fig. 2.

The drive-up ordering station 14 has a posted visual menu 30 which has the 5 description and order number of various food items. A receiver 32 is tuned to the transmitter 24. The station 14 also has a second processor 34 which is adapted to decode information received from the transmitter 24 through the receiver 32 and produce decoded information. The decoded information, for example, item description and price, is displayed on a display 36. A second memory 38 stores item numbers, descriptions, and prices which may be 10 received from a point-of-sale system 40 through a communications link 42. The second memory 38 and second processor 34 may be discrete components, or they may both be in an Application Specific Integrated Circuit (ASIC) as seen in fig. 4.

The transmitter 24 and receiver 32 may operate either with radio frequency (RF) v transmissions or with infrared (IR) transmissions. 15 The remote ordering system 10 further comprises remote software executing in the first processor 22 and managing the remote input device 12; and ordering station software executing in the second processor 34 managing the ordering station 14. A flowchart ofthe remote software and ordering station software is shown in Fig. 5.

First, the ordering station software displays a “welcome” screen on the display 36. 2 0 The welcome screen may invite the customer to initiate a transaction by pressing the start key 16f on the remote device 12.

The customer then presses the start key 16f on the remote device 12, causing a signal to be sent from the transmitter 24 to the receiver 32. The start signal is decoded by the ordering station software executing in the second processor 34. 25 In the next step, the ordering station software causes an “enter item number” screen (FIG. 6A) to be displayed on the display 36. The item numbers available to the customer will be shown on the posted menu 30 along with a description of the item (hamburger, cheeseburger, etc.) associated with the item number. -8-

<img img-format="tif" img-content="drawing" file="IL155156AD00026.tif" id="idf0006" />

In response to the “enter item number screen,” the customer presses one or more of the numeric keys 16a to input the item number (FIG. 6B). The customer then initiates transmission of the item number to the ordering station 14 by, for example, pressing the “enter” key 16b.

The item number is received by the receiver 32 and decoded by the ordering station software executing in the second processor 34. The ordering station software then associates the item number with an item description by looking in a table held in the second memory 38.

Next, the ordering station software sends an “item identifier and quantity” screen (FIG. 7) to the display 36. This screen invites the customer to enter the quantity of this item 10 desired.

The customer inputs the quantity of this item desired by using the numeric keys 16a and optionally the quantity add key 16d and/or quantity subtract key 16e. The customer then initiates transmission of the item quantity by, for example, pressing the “enter” key 16b.

The receiver 32 receives the item quantity for the first item and passes this to the 15 second processor 34 for decoding. The second processor then makes an entry for the quantity of the first item in the second memory 38. The second processor looks up the price nf this: item from a table maintained in the second memory 38 and calculates an item total for the first item. The ordering station software then transmits an item total screen (FIG. 8) for the first item to the display 36. 20 25

When the customer presses the “enter” key again, a transmission signaling pressing of the “enter” key is sent to the ordering station 14. The ordering station software then transmits an “enter/remove/finish" screen (FIG. 9) to the display 36.

The' customer has three choices by which he may respond to the “enter/remove/finish” screen.

If the “enter” key is pressed, the remote device 12 signals the ordering station 14 to bring up an “enter item number” screen (FIG. 6A) to begin the process described above for ordering another item. -9-

<img img-format="tif" img-content="drawing" file="IL155156AD00027.tif" id="idf0007" />

If the “remove” key 16c is pressed, the remote device 12 signals the ordering station to bring up a “remove item” screen (FIG. 1 IA). Tliis screen will list the item(s) ordered by item number, description, and quantity and display an order total. Optionally, the order subtotals may also be displayed (FIG. 1 IB). By using the numeric keys 16a, the customer 5 indicates which item number to remove, then presses the “enter” key to signal the ordering station software to remove that item from the order. The ordering station software then redisplays the “enter/remove/finish” screen.

If the “finish” key 16f is pressed, the remote device 12. signals the ordering station to calculate an order total for all items and quantities ordered. The ordering station software 1 o then causes an order total screen (FIG. 10) to be displayed on the display 36.

The ordering station software then sends the order information to the point-of-sale system via the communications link 42.

The.point-of-sale system may load item numbers, descriptions, and prices into the ordering station through the communication link 42. 15 A generalized remote ordering apparatus comprises an input device 112 having a keypad 116, a battery 18, a first memory 20, a first processor 22, and a transmitter 24 (see figs. 3 and 12A). The first memory 20 and first processor 22 may be discrete components, or they may both be in an Application Specific Integrated Circuit (ASIC) as seen in FIG. 3. A user/server indicator may be stored in the first memory 20 for transmission to the ordering 2 0 station 140 to identify the user/server.

The remote ordering apparatus further comprises an ordering station 140 unconnected to the input device 112, the ordering station 1.40 having receiver 32 tuned to the transmitter 24. The remote ordering station 140 also has a second processor 34 which is adapted to decode information received from the transmitter 24 through the receiver 32 and produce 2 5 decoded information. The remote ordering station 140 also has a display 36 adapted to display the decoded information. A second memory 38 stores item numbers, descriptions, and prices which may be received from a point-of-sale system 40 through a communications -10- link 42. The second memory 38 and second processor 34 may be discrete components, or they may both be in an Application Specific Integrated Circuit (ASIC) as seen in FIG. 4.

The input device 112 may have a display window 114 for displaying information. Preferably, the display window 114 is a liquid crystal display. 5 The input device 112 may have an order ready indicator 118 which is turned on by transmission from the ordering station 140 when an order is ready for pickup. Preferably, the order ready indicator is a lighted indicator such as an LED, but could also be a chime or vibrator.

The keypad 116 preferably has a plurality of numeric keys 116A to input selections 10 from menu items and customer data. Most preferably, the numeric keys 116A further comprise keys labeled 0 through 9, as shown in FIG. 12A. For example, a standard telephone keypad could be used as the numeric keys 116A.

The keypad 116 further comprises an order send button 120 which is pressed to transmit an order to the ordering station 140. Λ 15 The keypad 116 further comprises a recall/change button 122 which can be used to recall or change a previously submitted order by entering the order number and pressing the recall/change button 122.

The input device 112 preferably has a credit card slot 128 for swiping a credit card to read the magnetic strip on the credit card. The input device 112 may also have a credit card 2 0 signature block 126 adapted to electronically record the signature of a credit card holder.

The transmitter 24 and receiver 32 may operate either with radio frequency (RF) transmissions or with infrared (IR) transmissions. Preferably, RF transmissions are used.

The remote ordering apparatus preferably comprises a plurality of the input devices 112, each of said plurality of input devices 112 being separately transportable away from the 2 5 ordering station 140. -11- A customer of the service facility may place orders or acquire other information from the service facility by means of a method using the generalized remote ordering apparatus.

The service facility provides an order code to the customer who is using the input device, after correlating the order code to a predetermined order. For example, order code 1 5 could be correlated to a hamburger, fries, and a coke. The user of the input device then enters the order code into the input device 112 by means of the keypad 116 and presses the order send button 120, which causes the order number to be transmitted to the ordering station.

The user may operate the input device 112 either inside or outside the service facility, depending on the range of the transmitter 24. 10 To provide order codes to the general public, the owner of the service facility may post a menu of order codes on a World Wide Web page. For example, if a retail store is having a special promotion, the store may post order codes for items which are on sale on its web site. The shopper then prints our a list of these order codes and, after entering the store, enters the order codes into the input device 112 and transmits them to the ordering station 15 140.

Alternatively, the service facility could also provide a catalog for use by a customer, which each customer being given an input device for shopping, and the catalog having the order codes. The input device 112 could be programmed to accept a number of order codes and transmit them serially to the ordering station 140 with one press of the order send button. 2 0 When the order is ready, the order ready indicator will be turned on, and the customer may pick up the order.

In an alternative arrangement, the service facility may reveal an order code, on a web site or otherwise, only after verifying the identity of the requester, and may additionally require the requester to pay for the order with a credit card number before receiving the order 2 5 code. In another arrangement, the requester pays for the order after entering it by swiping his credit card through the credit card slot 128, which transmits the credit card number and expiration date to the point-of-sale system through the ordering station 140.

The input device 112 may be incorporated into a cellular telephone, so that orders may be transmitted to the service facility over the-telephone network. -12-

Another embodiment of a generalized remote ordering apparatus is shown in Figs. Μ Ι 6 as reference numeral 210.

The generalized remote ordering apparatus 210 comprises an input device 212 and an ordering station 140 unconnected to the input device 212. ) 5 The input device 212 further comprises a keypad 216, a battery (not shown), a first memory 20, a first processor 22, and a transmitter 224. The first memory 20 and first processor 22 may be discrete components or they may be in an Application Specific Integrated Circuit (ASIC) as seen in FIG. 3.

The input device 212 also comprises a bar code reader 226 adapted to read bar code 1 o labels L.

The ordering station 240 has a receiver 32 adapted to receive information from the transmitter 224. The ordering station 240 also has a second processor 34 which is adapted to decode information received from the transmitter 224 through the receiver 32 and produce decoded information. A second memory 38 stores item numbers, descriptions, and prices 15 which may be received from a point-of-sale system 40 through a communications link 42.

The second memory 38 and second processor 34 may be discrete components, or they may both be in an Application Specific Integrated Circuit (ASIC) as seen in FIG. 4.

In one preferred embodiment, the input device 212 comprises a cellular telephone 250 and the receiver 32 comprises a telephone answering apparatus 242. 20 If the cellular telephone is analog, the transmitter 224 will include a modem.

In other embodiments, the transmitter 224 and receiver 32 operate in the infrared spectrum or the radio spectrum.

The apparatus 210 may also have a global positioning system (GPS) transceiver 260 that communicates with one or more GPS satellites S. -13-

The apparatus 210 may also have a personal identification apparatus 270 adapted to identify the user of the input device 212. The personal identification apparatus preferably is adapted to identify the user directly by some physical characteristic, instead of requiring the user to input a personal identification number (PIN). This provides additional security, because PINs can be stolen, but physical characteristics of the user cannot be copied.

The physical characteristic that may be used with the personal identification apparatus 270 may be any physical characteristic of the user, but preferably is selected from the group consisting of bioelectric, biochemical, and biomechanical characteristics.

For example, the personal identification apparatus 270 may be adapted to identify the user’s thumbprinf or the user’s retinal pattern.

Applications of the apparatus 210 may now be illustrated.

If the input device 212 is a cellular telephone 250 equipped with a bar code reader 226, the user may order an item from his home or car for later pickup at a store or restaurant. The store or restaurant inay publish a menu of items with corresponding bar codes, either in print or on the World Wide Web. To order an item, the user would dial a central number at which the ordering station is located and the call would be answered by the telephone answering apparatus 242. A series of voice instructions would instruct the user to read the bar code using the bar code reader 226. The ordering station 140 would then communicate with the point-of-sale system to record the sale. In addition, the customer may be required to swipe a credit card through the credit card slot 128, either at home or when at the store.

In another application, the GPS transceiver 260 would indicate the user’s location, precise to within 10 feet, and the input device 212 would transmit this location to the ordering station 140 during the ordering process. A delivery person, equipped with another GPS transceiver,· would input the GPS coordinates into his transceiver and would be able to go directly to the location at which the ordering user is located. This would be of great value in an environment such as a stadium.

In another application, the user may place an order through the store or restaurant’s World Wide Web site, using any standard ordering process. When the user arrives at the -14- store or restaurant, the user may activate the input device 212 in order to indicate to the ordering station 140 that the user is present and ready to pick up the item.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present 5 embodiment be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
