Abstract
Abstract A cash accounting and surveillance system for games, whereby operation of a number of player operated gaming devices may be monitored for purposes of detecting abnormal operation and/or cheating and for providing automatic accounting information for record keeping and pilferage detection purposes. The system utilizes a node concept with each node having a non-volatile data storage capability and a communications capability for communicating with each of a plurality of gaming devices coupled to the node. The exemplary embodiment disclosed operates in conjunction with slot machines having mechanically rotatable reels and a microprocessor control system for randomizing the reel stopping payouts and other machine functions. Alternate embodiments are disclosed.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
141 words
A cash accounting and surveillance system for gaming machines comprising; first means within each machine for monitoring the input of items of monetary value and the payout of items of monetary value, and for maintaining digital signals indicative of the cumulative numbers thereof, second means within each machine for communication over data lines, said second means having a unique address on said communication lines and being responsive thereto to transmit said signals of said first means on said data lines, node means coupled to a plurality of said second means through said data communication lines, said node means including means for polling all of said second means coupled thereto and for receiving said digital signals therefrom, said node means having non-volatile storage means for maintaining data responsive to said digital signals in spite of system power loss and node means failures.
Claim 2
Dependent Claim
141 words
A cash accounting and surveillance system for gaming machines comprising; first means within each machine for monitoring the input of items of monetary value and the payout of items of monetary value, and for maintaining digital signals indicative of the cumulative numbers thereof, second means within each machine for communication over data lines, said second means having a unique address on said communication lines and being responsive thereto to transmit said signals of said first means on said data lines, node means coupled to a plurality of said second means through said data communication lines, said node means including means for polling all of said second means coupled thereto and for receiving said digital signals therefrom, said node means having non-volatile storage means for maintaining data responsive to said digital signals in spite of system power loss and node means failures.
Claim 3
Dependent Claim
22 words
The system of claim 1 wherein said first means includes means for maintaining said digital signals in spite of system power loss.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
56 words
The system of claim 1 further comprised of means for sensing the opening of a drop door indicating removal of accumulated items of monetary value, said first means further being a means responsive to said drop door opening for maintaining additional digital signals indicative of said cumulative numbers at the last opening of said drop door.
Claim 8
Dependent Claim
45 words
The system of claim 1 further comprised of exception code generating means for sensing certain machine malfunctions and types of cheating and providing exception code digital signals responsive thereto to said second means for communication to said node means upon polling of the respective machine.
Claim 9
Dependent Claim
41 words
The system of claim 7 wherein said node means includes means for polling each of said machines for selective transmission of said digital signals indicative of the input and output of items of monetary value or said exception code digital signals.
Claim 10
Dependent Claim
19 words
The system of claim 1 further comprised of means in said node means for communicating with a host computer.
Claim 11
Dependent Claim
27 words
