Abstract
In one embodiment, data is received from a plurality of token devices and the rate of transmission is adjusted to match a lowest reception rate of the plurality of token devices using the data.
Claims55
A method, comprising:
- receiving data from a plurality of token devices;
- and
- adjusting a transmission rate to match a lowest reception rate of the plurality of token devices using the data.
A method of communication, comprising:
- initiating a speed sequence and start identifier sequence from a master device;
- replying with an acknowledge from a token device that the speed sequence and start identifier sequence were received;
- and
- transmitting a command sequence from the master device when the acknowledge from the token device has been received.
A computer-readable medium having stored thereon a data structure comprising:
- a first data field containing data that identifies a token device;
- a second data field containing data that identifies a command to be communicated to the token device;
- and
- a third data field containing data the identifies information to be conveyed to the token device.
The computer-readable medium of claim 25 wherein the first data field comprises an eight bit word.
A computer-readable medium having computer-executable instructions for performing the steps comprising:
- receiving data from a plurality of token devices;
- and
- adjusting a transmission rate to match a lowest reception rate of the plurality of token devices using the data.
The computer-readable medium of claim 30 further comprising the step of sending second data to the plurality of token devices at a first transmission rate before receiving the data from the plurality of token devices.
The computer-readable medium of claim 31 wherein the step of adjusting the transmission rate is performed if the first transmission rate exceeds the lowest reception rate of the plurality of token devices.
The computer-readable medium of claim 35 wherein the plurality of token devices derives the speed sequence using a master device cycle time.
A gaming system comprising:
- a master device that transmits data;
- and
- one or more token devices that receive the transmitted data, wherein the master device adjusts a transmission rate based on a lowest reception rate of the one or more token devices.
A gaming system comprising:
- means for transmitting data at a master device, wherein the data is transmitted to one or more token devices;
- and
- receiving means at the one or more token devices, for receiving the data, wherein the means for transmitting is adjusted to transmit at a rate based on a lowest reception rate of the one or more token devices.
A communication device comprising:
- a processor;
- a memory controlled by the processor to store token device identifiers, and instructions to initiate an identifier sequence with token devices, receive and send commands and data to token devices;
- and
- a communication interface to receive and send the token device identifiers, commands, and data.
A communication device comprising:
- means for sending an speed sequence and start identifier sequence;
- means for sending a command sequence;
- and
- means for checking to see if a token device has received the speed sequence, start identifier sequence, and command sequence.
A communication device comprising:
- means for receiving an identifier sequence;
- means for acknowledging receipt of the identifier sequence;
- means for receiving a command sequence that follows the means for acknowledging and
- means for providing a data sequence based the received command sequence.
