  • Patent number: 7701344
    Abstract: Various techniques are disclosed for facilitating tracking locations of players and/or wireless communication devices in a casino network. In at least one embodiment, an electronically switched Doppler antenna array may be utilized to detect a first wireless signal from a first signal source. Bearing information may be generated using information from the detected signal. In at least one embodiment, the bearing information may include a first directional bearing to the first signal source. Using at least a portion of the first bearing information, a first location of the first signal source may be determined. According to specific embodiments, the first signal source may correspond to a wireless communication device such as an RFID-enabled player tracking card or gaming chip. In at least one embodiment, a current location of the wireless communication device may be automatically tracked in real-time as the wireless communication device is moved through a first region of the casino.

  • Publication number: 20090124383
    Abstract: Methods and apparatus for use with an interactive gaming table. In one aspect, an administration tool is provided for use with an interactive gaming table. The interactive gaming table includes a playing surface for displaying a game, a signal source, and a signal collector. The administration tool includes a primary identifying indicia that uniquely identifies the tool to the gaming table by reflecting a signal emitted by the signal source such that the signal reflected by the primary identifying indicia is received and analyzed by the signal collector. The administration tool also includes a secondary identifying indicia that is recognized by the gaming table by reflecting the signal emitted by the signal source such that the signal reflected by the secondary identifying indicia is received and analyzed by the signal collector, wherein a present state of the displayed game is changed based on a player's action taken with the tool.
