Abstract: A radio-frequency identification (RFID) tag includes an antenna with a relatively large number of turns and is de-tuned from an excitation frequency of an RFID reader. The RFID tag, when grouped with other similar RFID tags, uses resonant inductive coupling to channel the magnetic flux density field (B-field) through the group to power each of the tags in the group. As a result, the sensitivity is increased as compared to using an antenna having a smaller number of turns.

Abstract: A radio-frequency identification (RFID) tag includes circuit elements that result in a resonant frequency that differs from the excitation frequency of an RFID reader. The RFID tag, when stacked with other similar RFID tags, channels the magnetic flux density field (B-field) through the stack to power each of the tags in the stack. As a result, the B-Field is collimated in a manner that increases the sensitivity (read range) in one dimension (up a stack of chips) while simultaneously limiting the sensitivity in the two lateral dimensions, thereby providing precise spatial resolution of each tag as to its location on a gaming table.

Abstract: A gaming table contains a number of antennas that are de-tuned from the resonant frequency of a single RFID tag. This increases the power required to read the single tag but matches the resonant frequency for reading a stack of RFID tags. The gaming table may further include a network analyzer and a set of capacitors that are dynamically switched among the antennas according to measuring the reflection coefficient of the antennas.

Abstract: A gaming table includes a network analyzer. The network analyzer detects antenna reflection coefficients faster than RFID tags can be read, enabling game state information to be monitored quickly.

Abstract: A preferred embodiment of a Pai Gow gaming table (352) is equipped with a system (460) that implements real-time tracking of gaming tiles (366) to mitigate risk of dealer or player cheating behavior during game play. Each gaming tile has a machine-readable tile identifying tag. The gaming table has a playing surface (350) that includes a pre-assigned woodpile position (358) and multiple pre-assigned player positions (54). Multiple woodpile position tile tag identification readers (362) configured to read the tile identifying tags are located in the pre-assigned woodpile position. Multiple player position tile tag identification readers (360) operatively associated with different ones of the pre-assigned player positions and configured to read the tile identifying tags are located in associated ones of the pre-assigned player positions. A controller (68, 464) operatively associated with the tile tag identification readers performs during game play real-time tracking of movement of the gaming tiles.

Abstract: The present invention provides a method for dealing a card game, comprising: calling for all pick-row, pair-plus bonus, and no-peek bonus bets; dealing three rows of two card poker hands face up in positions A, B, and C; confirming whether there exists a qualifying card in one of the hands; collecting all losing pick-row wagers if none of the hands qualify; giving action to all pick-row bets if there is a qualifying hand; establishing a winning two-card poker hand among A, B, and C; dealing three sets of three cards face up to each row to complete five card poker hands in positions A, B, and C; establishing all no-peek bonus qualifying hands; announcing a value of all qualifying five-card poker hands; and reconciling winning and losing no-peek super bonus bets and, paying winning bets from right to left.
