First Claim
Patent Images
1. A system for locating gaming tokens on a gaming table, comprising:
- a first set of antennas oriented in a first direction, wherein the first set of antennas defines a betting area of the gaming table;
a second set of antennas oriented in a second direction that differs from the first direction, wherein the first set and the second set are overlapping; and
a control circuit, coupled to the first and second sets, that is configured to selectively energize the first and second sets, that is configured to receive a first plurality of signal strengths resulting from detecting a radio frequency identification (RFID) gaming token in the betting area according to the first set being selectively energized, that is configured to receive a second plurality of signal strengths resulting from detecting the RFID gaming token in the betting area according to the second set being selectively energized, and that is configured to determine a location of the RFID gaming token in the betting area by comparing the first plurality of signal strengths and the second plurality of signal strengths.

Abstract
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.
