SYSTEM WITH REMOTE COMPUTER DATA ENTRY DEVICE, ASSOCIATED APPARATUS ^" AND METHOD OF USING SAME

BACKGROUND OF THE INVENTION This invention relates generally to a system including a remote, portable computer data entry device to enter data into a computer for processing, control and subsequent communication display, and more particularly, such a system in which the portable data entry device establishes data entry communication with the computer through airwave transmission.

More particularly, this invention relates to such a system which is used to convey and process information relating to operation of a restaurant or the like.

Recent advances in digital electronics have resulted in a variety of computers and other electronic apparatus suitable for use in small businesses. Typically, such personal or small business computers consist of a microprocessor-based, stored program control system for data manipulation, a random access memory, or RAM, for temporary data storage, floppy disk and hard disk drives for permanent large volume data storage, cathode ray tubes, or CRT's, for data entry and communication ' display and printers for hard copy output.

Known small computers are designed for data entry through a keyboard associated with a CRT, printer or both which are directly wire connected with the remain¬ ing portions of the system. Such limited data entry mechanisms restrict the utility of such computers and prevent such computer systems from functioning as effective communication systems. The inability to use such terminals remotely from the computer unless a hard wire connection is made therewith preclu_des many advantageous applications.

^Computer systems are known which have Dortable

-υREX remote data entry terminals and examples of these are shown in U.S. Patents 3,456,244; 3,624,615; 3,678,391; 3,872,445; 3,899,775; 4,019,174; 4,041,469; 4,300,040; and 4,301,506. Other remote computer terminals for data entry are shown in U.S. Patents 3,281,789;

3,937,004; 3,942,157; 3,956,740; 3,976,840; 3,976,995; 4,005,388, 4,007,443. Unfortunately, such data entry devices and the systems associated therewith are inadequate for numerous applications such as inventory taking and control and restaurant operation communica¬ tions because of the need for wire connections between the computer and the various input/output terminals.

For instance, there is a need in the operation of restaurant business for systems which permit entry of data to a computer from remote table locations. This need has not been met. Accordingly, in a typical modern restaurant, all order entry, processing, and service functions are performed manually. For example:

1) Reservations are manually recorded on a piece of paper at the reception desk.

2) Upon arrival of the customer, reservations are checked manually.

3) Table . availability is checked, manually.

4) The menu is presented to the customers and then orders are taken manually on an order form.

5) Then the order form or copy of' the order form is hand delivered to the kitchen and/or bar.

6) Based on this information, the chef and/or 'bartenders manually sort through the orders and prepare food and/or drinks,

7) The waitress returns to the kitchen and/or bar to pick up ordered food and/or drinks and serves the customer.

8) The final bill is prepared on yet another piece of paper. The waitress walks to the main reception area with the bills for financial computation which is

-3-

generally performed manually or occasionally by a stand alone terminal that requires keyboard entry of all order entries.

SUMMARY OF THE INVENTION It is therefore an object of this parent invention to provide an apparatus for entry of data to a computer in which a hand held, portable remote entry device is employed that transmits the data to be entered into the computer by airwave transmission. Interfacing means associated with the computer receives the airwave transmitted data, translates the received data into a form suitable for processing by the computer, and provides the translated data to the computer. It is also an object of this invention to provide a remote data entry device in conjunction with a restaurant communication system in which the remote, portable, entry device is used for direct entry of food orders into a computer which, in turn, processes and displays this information at kitchen termina-ls, busboy terminals and other locations to facilitate .and automate key restaurant functions such as table assignments, customer ordertaking, cooking, serving order analysis, inventory control and the like.

Advantageously, the resultant improved coimaunica- -tion customer service reduces labor.costs. In particular, the system functions to:

1. Minimize paperwork and time for order entry, billing, .order analysis and the like;

2. Provide management visibility and control through inventory control, -order analysis, employee analysis and the like;

3. Minimize unnecessary movement of employees transferring paper back and forth; and

4. Reduce the number of restaurant employees by reducing the number of waitresses to a few key waitresses with remote entry devices to take orders and increase

-$ϋS.EA customer contacts. The remainder of the service staff can be limited to performance of busbov functions.

Yet another object of the present invention is. to provide an interface for a computer which will 5 receive airwave transmitted data from a remote entry device and convert that data to a format, such as EIA standard format, which can be utilized by a computer.

A further object is to provide a system for direct communication between a computer and a remote entry 0 device in which error detection and correction , Security and cross talk or other interruption prevention features are. provided to facilitate reliable communication.

It is a further objective of the invention to provide a system employing a remote entry device and a computer. 5 in which one or more of the following devices or features are provided therewith.

1) One or more reservation display terminals, such as CRT displaying terminals, for selection and display of meal reservations, table assignments, telephone message 0 and the like.

2) One or more printers for printing itemized bills and reports.

3) One or more kitchen/cook CRT display terminals for instant display of food orders from the remote entry

15 device and for work-in-process analysis.

4) One or more bar/bartender CRT display terminals for instant display of drink orders from the remote entry device and for work-in-process analysis.

5) One or more service/busboy CRT display

>0 terminals for instant display of orders ready to be served and identification of tables ready to be cleared.

6) One or more management/manager CRT display terminals for instant display of floor status, order status, and data processing functions to generate

5 reports and the like.

7) One or more remote hand held, wireless remote entry devices (RED) for directly entering and retrieving customer orders to and from the computer;

8) One or more general purpose, small computers with a stored program control system and floppy disk and/or hand disks to perform long term data storage for menus and the like and electronic memory for short term storage, food orders, table assignments and the like and Computation ability if provided for order analysis, priority establishment and the like.

computer or main CPU, 2C with a stored control program; a plurality of remote entry devices 22, 24 and 26 with associated transceiver 36 and an interface circuit 38 for interfacing the main CPU 20 with the remote entry devices 22, 24 and 26. Off line data storage is provided by floppy and/or hard disks with Winchester disk shoe 40 or the like. Other inputs to and/or outputs from the computer 20 are provided by means of a plurality of CRT display terminals including: a printer 44 is coupled with the computer and provides one form of computer output; a modem 43 is provided for interfacing the computer 20 with a telephone network 44; a manager terminal, or MGMT, 46; a reservation/reception terminal, or REST, 48; a kitchen terminal, or KITT, 50; a bar terminal, or BART, 52; and a service terminal or, SERT, 54.

Additional KITT, SERT, BART, REST, PRNT, and/or MGMT may be added in any combination of multiple terminals, or MT's, 56.

The remote entry devices 22, 24 and 26 are used for entering customer orders to the computer 20 from remote locations through air transmissions by their associated transceivers 28, 30 and 32. Low power UHF radio wave transmission or light wave trans¬ mission may be used. The interface 34 includes the transceiver 36 for receiving and transmitting data and the interface circuit for translating the data into a form suitable for use by the computer 20 and providing it to the computer 20. Data from the computer 20 is also transmitted to the remote entry devices 22, 24 and 26 through the interface 34. Preferably the two-way communication between the

-Tϋ^SΞA

- 8-

remσte entry devices and the computer uses a standard EIA RS 232C type link.

Referring to Fig. 2 remote entry devices are sub¬ stantially identical to one another. Each of them, such as remote entry devices 24 and 26, include a microprocessor or CPO 58 for controlling communica¬ tions, storage and display. An alphanumeric and function keyboard is provided for manual entry of data and for manual control functions. A display, such as an LCD display 62, displays received or transmitted blocks of data in alphanumeric figures. A random access memory 64 is provided for temporary data storage, and a read only memory 66 is provided for program storage. A modulator 68 coupled with the computer 58 is used to impress carrier waves with data to be sent to the computer by transceiver 30 via. a broadcast antenna 29. Data from the computer 20, on the other hand, is demodulated by ^' a demodulator 72 and coupled to the microprocessor 58 through suitable interfacing circuitry (not shown) . The interface 34 likewise has a modulator 74 and a demodulator 76 for data to and from the remote entry devices.

Referring to Fig. 3, the remote entry devices may be very similar to commercially available hand held computers, such as made by Radio Shack or Matsushita with additional suitable hardware and software added for airwave communication. In addition to standard alphabetic keys 78 and numeric keys 80, control keys and associated computer functions are provided to simplify operation.

Actuation of key 82 labelled NEW clears remote entry device memory and causes transmission of an identification code associated with the remote entry device to enable subsequent transmission to and receipt by the computer 20 of new customer orders. -9-

A key 84, labelled CAN, allows cancellation of customer orders previously entered.

A key 86 labelled RECALL allows easy retrieval and display for amendment of customer orders previously entered.

The key 88, labelled FOR for forward and the key 90 labelled REV for reverse permits forward and reverse scanning on display 62 of individual orders associated with a given table order. Further control function keys include key 92 labbelled CHECK IN/OUT, which is used when a waitress wishes to check-in and check-out at the beginning and end of work shift, as will be explained in greater detail with reference to Fig. 6. ^{' *} A key 94 labelled REP is enabled whenever the computer is either in. he RECALL or the NEW mode to repeat entry of the same order when actuated. For instance, if four people ordered the same menu item", instead of the waitress keying, in each item four times individually, the entry could, be made simply by pressing the REP key three times after the initial entry is keyed in.

A key 96 labelled HELP is actuated when the user needs assistance to determine the meaning of pre— defined.menu codes. The system is .designed so that if menu code 101 stood for crab legs, then depres¬ sing key 96 and keying in the.number 101 will cause the display 62 to show CRAB LEGS.

The four keys 98, 100., 102 and 104, labelled Fl, F2, F3 and F4, respectively are used for functions which can be programmed into the computer 20 and 58 to suit specific needs of individual restaurants-

A plurality of lights are provided to indicate the overall status of the remote entry device. A light 106 labelled ONLINE LIGHT shows whether remote entry device is in communication with the computer.

-10-

Light 108, labelled BUSY signifies that the airwave communication channel with the computer is occupied by another remote entry device.

Light 110, labelled RCHG is provided to indicate when the battery power source of the remote entry device needs recharging. Alternately these status indications are provided on -the twenty-four character display 62 by appropriate messages, rather than by light indicators. Each of the remote entry devices also has a small antenna 112 to capture airwave signals trans¬ mitted by the computer 20 through interface 34.

The format for communication between remote entry devices 22,.24, and 26 and the computer 20 is illustrated in Figs. 4, 5 and 6. First the RED has food order data entered into it and the ENTER key 91 is actuated to send the data to the computer 20. In response to actuation of the ENTER key 91, the RED transmits an identification number code to the computer, Upon receipt of the identification, or ID number, the computer verifies that the number is a valid number from a list of valid numbers. If so, the computer sends the same ID number to all the RED's. Only the original RED which receives back to its own ID number is authorized to use the communication link for data transmission and is enabled to transmit. All other RED' s which received a number other than their own ID number are locked out and prevented from communicating until the computer sends a release code. The authorized RED then transmits in binary aεynchronis form,with start and stop pulses, a block of data, a block number or parity block' and its identification number, ID. The first transmission of the ID signifies start of data, and the last ID number signifies the end of data.

If the block of data is received error free with

- -11-

proper block parity, the computer sends a release signal which is received by all RED's. This unlocks all of the RED^f s and enables them to initiate communication with the. computer 20. If the data is received with error, the computer sends a retransmit code and the data must be retransmitted by the authorized RED.

The overall frame format of the data transmission is shown in Figure 4. While other coding formats could be used, it is prefered to use an ASCII code format with start, stop, and parity pulses. A seven or eight bit ASCII is adequate to efficiently transmit the food order and other information to the computer. Since there are multiple RED's it is possible that initially in the process of capturing the com¬ munication channel that more than one RED could transmit its ID number at the-exact same time, resulting in contention. In this event, the computer 20 will fail to recognize either ID# even ihough authorized and will send a release code. Upon receipt of the release code, each of the RED's will retransmit its data block in accordance with a built in, random retransmission sequence. So. that one of the RED's involved in contention will retransmit automatically before the other, and this captures the communication channel. In very large systems, multiple channels may be used so that plural RED's may simultaneously communicate with the _ computer 20.

As shown in Fig. 5,when the data link is captured and in use by one of the RED ' s and a user of another RED transmits data, the system will wait until the data communication link is not in use. Based on a built-in random start sequence, the RED will "camp" on the communication channel and automatically capture it when it opens after termination of communication with TUR X ' -12-

the prior RED.

The system of the present invention functions in accord ance with the logic flow chart of Fig. 7. As seen, reserva¬ tion information is entered into the computer from, and displayed at, the reservation terminal 48. In addition to the internal reservation information, the system provides for the display of messages to the parties for which reservations are made at the reservation terminal 48.

As also illustrated in Fig. 7, the orders entered by the RED is processed by the computer 20, and displayed at the kitchen terminal 50 and the bar terminal 52. The kitche terminal 50 and bar terminal 52 also have means for requesti information relating to completion of orders for pickup. The computer 20 processes the information and displays it at the service terminal 52 when orders are ready for service Finally, the computer operates a bill based on the order, an controls printer 42 to print the bill.

The system functions in sequence as follows:

1. The customer calls to make a reservation. The reservation terminal 48 display is used to determine the reservation status, and reservation data is entered in the computer based on such display.

2. The customer arrives at the restaurant and confirms his reservation. If made in advance at the receiption desk through the reservation terminal 48, the display verifies th prior reservation. At this point any telephone messages would be displayed upon request at the reservation terminal 48 and conveyed to the customer.

3. Based on table availability as shown at the reserva tion terminal display through the floor status display, Fig. 10, a specific table is assigned. The name of the customer is enterd for future telephoen messages, credit verification and personalized billing, etc.

4. Once the table is assigned and the customers seated the waitress with a RED takes food and drink orders. These orders are keyed into the RED on its keyboard with appropria control commands, and the RED instantly transmits the data through the air to the computer, as discussed above. -13-

5. The computer sorts these orders and displays them at the appropriate terminals for food and beverage prepara¬ tion. For instance, drink orders are displayed at the bar terminal 52 and food orders are displayed at the kitchen terminal 50.

6. Once food and/or drinks are ready, the cook and/or bartender would enter into the computer at their associated terminals the information that the orders are completed, and ready for pickup.

7. The computer then displays the completion status of the order on the display of the service terminal 54 to indicated that it is ready to be served.

8. After the order is served, the busboy enters this information into the computer 20 at the service terminal 54. The computer then transmits this information to the associated RED to alert the waitress for service- or supervision.

9. The waitress may change the order or add new items on the order using appropriate RED commands at any time.

In addition, .take-out orders, room-service, delivery order entries are optional abilities of the system.

10. Final billing would then be initiated by the waitres using an appropriate command on. the RED. _ The bill would then be computed by the computer. Billing is done by group or individually, and- the bills are printed on the printer 42.

11. At this time pertinent data such as table number, waitress number, food order, etc. would be stored with the background record- with date, time, etc., for order analysis, inventory management, etc,- as illustrated in Fig. 9.

More specifically, 'the various input and communication display functions for these terminals and the like functions performed in association with these and other terminals, are illustrated, in Fig. 8.

-14-

The initiating system, or background information perma¬ nently stored in the computer and used for the appropriate dis¬ plays of the various terminals and used to generate other information necessary to automate the restaurant system, is shown in Fig. 9.

Based on the information and subsequently entered infor¬ mation the computer performs the following functions:

1. Interface with remote entry device (RED) via airway link.

2. Interface with CRT's printers, floppy and hard disc storag

3. Store current order information for sorting, display etc. for each table in its allocated read/write buffer and all pickup/delivery information in a single allocated read/write buffer until a bill has been generated.

4. Prepare and store reservation information.

5. Store completed order information on disk (after bill generation) for reporting and analysis purposes.

6. Update table status.

7. Respond to RED requests such as RECALL or HELP.

8. Respond to CRT requests such as displays requested.

9. Respond to "accounting" requests such as report genera¬ tions by way of the printer 42.

10. Initialize and edit user programmable data such menu item member and descriptions, menu item prices, selected reports to be generated, total no. of tables, etc.

11. Respond to display terminals, RED's and hardcopy terminal user errors.

12. Maintain system real time clock and calendar

13. Perform arithmetic functions for billing and reporting, et
