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.

De-tuned multiple RFID antenna arrangement for gaming

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.

RFID tags with B-field focusing

An anatomical sensing system-guided prostate procedure device that includes a housing having a proximal end and a distal end. The housing may be divided into a distal housing section, a mid housing section, and a proximal housing section, wherein the distal housing section is configured for insertion into the anus and retention in the rectum of a subject. The device further includes an instrument convergence point disposed between the proximal end and the distal end, the convergence point configured to allow an instrument pass though the instrument convergence point at a variable angle; and an instrument angle orienting system at the proximal end of the housing, the angle orienting system directing an orientation of the variable angle about the convergence point. Methods of the using an anatomical sensing system-guided prostate procedure device and system including the same.

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.

Using antenna reflection coefficients to detect events in a gaming environment

An RFID system includes multiple antennas and uses amplitude and phase information of the RFID signals received by each antenna to determine the position of RFID tags in the vicinity. More than one antenna can receive the RFID signals during a single read cycle, enabling the RFID system to operate more quickly than a system that energizes antennas separately.

RFID antenna array for gaming

A system and method of locating gaming tokens on a gaming table. Two sets of overlapping antennas are arranged in intersecting directions. The system uses the data from intersecting antennas to determine the positions of the gaming tokens. Having overlapping antennas reduces dead spots.

Overlapping antenna arrays for gaming

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. The network analyzer detects changes in the reflection coefficients that result from movements of a human appendage, enabling the system to change game states in response to the detected hand movements.
