Abstract

An operating system for a gaming system includes a data producer which generates non-reproducible data relating to a transaction carried out in respect of the gaming system. A data consumer is in communication with the data producer for storing data relating to the non-reproducible data. A game controller is in communication with the data producer and the data consumer which effects communications between the data producer and the data consumer by means of a transaction-based protocol. The invention also relates to the use of data storage device for a gaming system that includes a local power supply.

Claims

1. A meter sub-assembly for a gaming system, the meter subassembly including:

at least one electromechanical meter which records data relating to transactions occurring in the gaming system; and

a local power supply unit associated with said at least one electromechanical meter, the local power supply unit being powered by a power supply unit of the gaming machine and the local power supply unit providing sufficient hold-up time to enable said at least one electromechanical meter to complete a data recording operation in the event of a power failure.

6. The sub-assembly of claim 1 in which an alteration in state of the at least one electromechanical meter when it records data relating to transactions occurring in the gaming system constitutes non-reproducible data to be stored in a data consumer of the gaming system.

2. The sub-assembly of claim 2 in which a plurality of electromechanical meters are mounted on a board with the local power supply unit, a power fail detect/warning means, a meter update means, a memory means and a communication means for communicating with a controller of the gaming system.

3. The sub-assembly of claim 2 in which the meter update means is operable to vary the sequence of power to the meters during the hold-up time.

4. The sub-assembly of claim 3 in which the meter update means is a microcontroller.

5. The sub-assembly of claim 2 in which the communication means makes use of a universal serial bus (USB) interface.

7. A method of updating data on meter RAM of a gaming system, the method including:

creating a backup copy of original meter data and storing the backup copy in a predetermined, second data storage location of a memory device of the meter;

receiving new meter data and overwriting the original meter data at an original, first data storage location of the memory device; and

prior to implementing the action of overwriting the data, changing the status of a status indicator.

8. The method of claim 7 in which the status indicator is a flag and in which the method includes examining the status of the flag every time power is restored after a power failure to determine if the power failure interrupted a meter update.

9. The method of claim 7 which includes, if there has been an interruption to the meter update, using the contents at the second data storage location to restore the original meter data.

10. The method of claim 9 which includes writing the data at the second data storage location to the first data storage location to overwrite any data at the first data storage location potentially corrupted due to the power failure.

11. The method of claim 8 which includes, once an updated transaction has been received by the memory device and a backup copy has been made, changing the flat status to “

updating”

.

12. The method of claim 11, which includes, processing the transaction and, when complete, changing the flag status to “

not updating”

.

13. A data updating arrangement for meter RAM of a gaming system, the data updating arrangement including:

a memory device including a first data storage location for storing original meter data; and

a second data storage location for storing a backup copy of the original meter data and for enabling new meter data to be written to the first data storage location; and

an update status indicator for indicating the status of updating data at the first data storage location.

14. The data updating arrangement of claim 13 in which the update status indicator is in the form of an update status flag which indicates the status of a meter update at the first data storage location.

15. The data updating arrangement of claim 14 in which the status flag takes one of two states, either “

updating”

or “

not updating”

.

16. An electronic gaming machine which includes:

a game controller board including a game controller;

at least one peripheral device by means of which a game transaction is effected, said at least one peripheral device communicating with the game controller by means of a transaction-based protocol; and

a data storage sub-assembly for storing data relating to said transaction, the data storage sub-assembly communicating with the peripheral device and the game controller by means of the transaction-based protocol, the data storage sub-assembly including a data store for storing data relating to said at least one peripheral device, and a dedicated controller for controlling operation of the data store.

17. The gaming machine of claim 16 in which the data storage sub-assembly includes a local power supply which receives power from a main power supply of the gaming machine.

18. The gaming machine of claim 17 in which the local power supply communicates with the dedicated controller of the data storage sub-assembly to alert the controller of the data storage means to a power fail event to enable the controller to effect recording of data during a hold-up time of the local power supply.

19. The gaming machine of claim 16 in which the transaction based protocol is a USB protocol.
