Abstract

In conjunction with the play of the game of Keno, a combination ticket holder and transmitter-receiver is located at each player'"'"'s table. Each player'"'"'s transmitter is coded with a number (e.g., 60,000) of two-tone sequential codes which are transmitted to Keno runners preassigned to specific tables and to a game controller in the Keno lounge. Each player'"'"'s receiver displays 80 LED digits, numbered 1-80, or other indicatable symbols, and preferably is a super hetradine narrow band receiver to minimize interference from adjacent and co-channel users. Signals are converted from analog to digital when the symbol indicators are connected, and remain displayed until reset for the next game. Each runner has a portable unit with a receiver also which has indicators numbered to identify the players and which preferably also is a super hetradine, dual tone, sequentially coded unit. It converts the tones generated by the player'"'"'s transmitter into the appropriate display enabling the runner to identify the table requesting assistance. The game controller'"'"'s console has two receivers. One is identical to that of the player to allow the controller to monitor and verify the game scores. The other receiver is identical to that of the runner and displays all table numbers of all runners. The controller utilizes two transmitters. A first transmitter, identical to that of the player with coding numbering the same quantity of runner boards, enables the controller to request a Keno runner to his location in the same fashion as the player. The second transmitter has encoding compatible to the player'"'"'s receiver for transmissions of the game scores, game number, status of game or any other required information.

Claims

1. A paging and servicing system for transfer of information among at least three classes of parties comprising:

a plurality of paging stations, included within a first of the classes, each having a transmitter and a receiver;

at least one servicing station, included within a second of the classes, for said paging stations and having receiver means for receiving first signals transmitted from said paging stations; and

a control station, included within a third of the classes, for said paging and servicing stations and having a receiver for receiving the first signals transmitted from said paging stations and a transmitter for transmitting second signals directly to said receivers at said paging stations and at least periodically to said receiver means at said servicing station.

2. The system as defined in claim 1 wherein said paging station transmitters have means for differently encoding the first signals respectively for identifying each of said paging stations, and said paging stations having a plurality of manually-actuable controls coupled respectively to said paging station transmitters which thereby transmit the first signals to said servicing and control stations for identifying said paging stations.

3. The system as defined in claim 2 further including displays coupled respectively to each of said paging station receivers and to said control station, and wherein said control station includes manually-actuable controls coupled to said displays at least in part through said control station transmitter for encoding the second signals and for enabling information contained in the second signals to be displayed at said control station and at said respective paging stations.

4. A paging and servicing system for transfer of information among at least three classes of parties comprising:

a plurality of paging stations, included within a first of the classes, each having a transmitter and a receiver, said paging stations having a plurality of manually-actuable controls coupled respectively to said paging station transmitters which thereby transmit first signals, and having means for differently encoding the first signals respectively for identifying each of said paging stations;

one or more servicing stations, included within a second of the classes, for said paging stations, and each having a receiver for receiving the first signals transmitted from said paging stations;

a control station, included within a third of the classes, for said paging and servicing stations and having a receiver for receiving the first signals transmitted from said paging stations, and a transmitter including first means for transmitting second signals to said receivers at said paging stations and second means with manually-actuable controls coupled thereto for transmitting third signals to each said servicing station receiver for paging one or more of the second class of parties; and

displays coupled respectively to each of said paging station receivers and to said control station, and wherein said control station includes manually-actuable controls coupled to said displays at least in part through said control station transmitter which is thereby encoded with the second signals and which is thereby enabled to have information contained in the second signals to be displayed at said control station and at said respective paging stations.

5. The system as defined in claim 4, useful in a play of a sequence of events, wherein said control station further includes a switching device coupled to said displays, at least in part through said control station transmitter, for changing the sequence.

6. The system as defined in claim 5 wherein said receivers and transmitters are crystal-controlled with 100 milliwatts of power, said transmitters are coded with 60,000 two-tone sequential codes which are received and decoded simultaneously by said receivers, and said receivers are super hetradine, dual tone, sequentially coded narrow band receivers for minimizing interference from adjacent and co-channel transmitters.

7. The system as defined in claim 6 wherein each of the events comprises a Keno game, wherein said displays each comprise a number of digits, and wherein said control station manually-actuable controls comprise a keyboard having an equal number of digits.

8. The system as defined in claim 4 wherein said first of said classes comprises groups of Keno players each being placed respectively at said paging stations, said second of said classes comprises one or more Keno runners in which one Keno runner per one of said servicing stations is responsible for each of said groups of Keno players, and said thrid of said classes comprises a controller for all of said groups of Keno players and said Keno runners.

9. The system as defined in claim 8 wherein each of said paging station manually-actuable controls defines a flasher and oscillator switching device respectively coupled to said paging station transmitters and including a light and means for causing flashing of said light upon a first actuation of said switching device, and for causing extinction of said light upon a second actuation of said switching device.

10. A method for transferring information among at least three classes of parties, comprising the steps of:

transmitting signals from a first of the classes to the second and third of the classes; and

transmitting signals from the third of the classes to the first of the classes and at least periodically to the second of the classes in response to the signals received from the first of the classes.

11. A paging and servicing system for transfer of information among at least three classes of parties comprising:

a plurality of paging stations, included within a first of the classes, each having transmitters and receivers;

at least one servicing station, included within a second of the classes, for said paging stations and having receiver means for receiving first signals transmitted from said paging stations; and

a control station, included within a third of the classes, for said paging and servicing stations and having

a receiver for receiving the first signals transmitted from said paging stations, and

a transmitter having means for transmitting second signals to said receivers at said paging stations, and further means for transmitting third signals to said servicing station receiver means for paging a party of the second class.
