  • Publication number: 20240257603
    Abstract: Systems, methods and computer-readable storage media utilized to create and perform an RF enabled card game table. One implementation includes an RF reader associated with the game table receiving RF signals transmitted by a plurality of RF tags associated with playing cards and chips. The implementation can further include a processor communicatively coupled to the RF reader, the processor rendering a game state from the RF signals, forming and transmitting, via an API, a packet including the rendered game state. RF signals received from an RF tag having a Received Signal Strength Indicator (RSSI) lower than a predetermined threshold can be ignored by the system when a surrounding noise level interferes with transmission of the RF signals and/or the RF tag is disposed at a predetermined distance from the RF readers. RF signals received from an RF tag not affecting the rendered game state can be also ignored by the system.

  • Patent number: 6361207
    Abstract: An electrical termination system (100) includes a monolithic electrical termination device (101) for providing an electrical termination to an electrical circuit. The device (101) includes a ceramic substrate (106) supporting an RF termination resistor element (102) and a thermistor element (104) and providing a fast temperature conducting path therebetween. A ceramic cover (105) and the ceramic substrate (106) provide an enclosure enclosing the RF termination resistor element (102) and the thermistor element (104). The thermistor element (104) senses a temperature corresponding to the RF termination resistor element (102) and provides a signal representative of the temperature sensed by the temperature sensor element (104).

  • Patent number: 6326862
    Abstract: An electrical termination system includes an electrical contact electrically connected to an RF resistor (224). A housing (102) at least partially encloses the RF resistor (224). In one alternative, the housing (102) includes an electrically conductive surface located at a first distance relative to the RF resistor (224) to provide a reactance at the RF resistor (224) to reduce reflected energy at the electrical contact for a wide band RF signal present at the electrical contact. In a second alternative, a surface of a dielectric substrate (602) is located substantially adjacent to the RF resistor (224) to provide a reactance at the RF resistor (224) to reduce reflected energy at the electrical contact.
