Abstract:
1. A roulette table, comprising an electronic system having at least one electronic circuit, a number of M antennas, a Code Division Multiple Access (CDMA) transmitter for sending a number of M orthogonal code sequences via the antennas, and a contactless communication interface for receiving the position from an electronic memory of the electronic circuit, in which the antennas are arranged below stake fields of the roulette table, and having chips, in which each chip is equipped with an electronic circuit, and in which the electronic circuit comprises the following: a CDMA receiver to receive a number of M orthogonal code sequences; an electronic memory, in which an allocation instruction is stored, wherein through the allocation instruction each code sequence is assigned to one of the antennas, wherein the allocation instruction contains information regarding the spatial location of the respective antenna; a processor for accessing the electronic memory to determine the position of the electronic circuit relative to the antennas by determining, with help of the code sequences received from the CDMA receiver, information regarding the spatial locations of those antennas by which the code sequences were received, and by deriving from the detected spatial locations of the antennas the position of the electronic circuit and producing a position signal therefrom; and a contactless communication interface for transmitting the position signal.
