摘要： The game table reading system 1 comprises: reading antennas 7 for each of a plurality of reading areas of a game table 2; read-restriction antennas 10 for each of the plurality of the reading areas, the read-restriction antennas 10 restricting the RFID tag embedded in a game token 5 placed in the corresponding reading area from being read by the reading antenna 7 corresponding to the other adjacent reading areas; a reading control device 9 that controls the reading antennas 7; and a read-restriction control device 12 that controls the read-restriction antennas 10. The read-restriction control device 12 causes the read-restriction antennas 10 corresponding to the reading areas adjacent to the reading areas corresponding to the reading antenna 7 that the reading control device 9 causes to read, in synchronization with the reading control device 9.

摘要： A control unit for controlling wireless data transmissions in a mobile communications system provided on board an aircraft, a mobile communications system having a control unit of this type, an associated method for controlling wireless data transmissions in a mobile communications system provided on board an aircraft, and a computer program for carrying out the method. The control unit comprises a generating component for generating a band-limited masking signal for masking terrestrial mobile communications signals in a first frequency band and a combining component for combining the band-limited masking signal and a service signal for the wireless transmission of data in a second frequency band different from the first frequency band. The combining component is configured to combine the masking signal and the service signal so that terrestrial mobile communications signals in a third frequency band formed by overlapping of the first and the second frequency band are masked.

摘要： A system and method for near field communications is provided. The system includes a near field generator configured to generate a near field detectable signal comprising information, a near field detector configured to receive the near field detectable signal and output the information, and an Electro-Magnetic (EM) Radio Frequency (RF) jamming transmitter configured to radiate an EM RF jamming signal, in order to jam reception of EM RF signals in the vicinity of at least one of the near field generator and near field detector.

摘要： A system and method for preventing use of cellular/PDA devices on-board a mobile platform, such as an aircraft. The system involves using the shielding of the fuselage of the aircraft to provide a first degree of signal-to-noise ratio attenuation of signals from terrestrial wireless access points entering into the interior cabin area of the aircraft. A noise floor lifter subsystem raises the noise floor level within the aircraft to provide a second degree of attenuation of the signal-to-noise ratio of the signal entering the aircraft. By using the shielding of the fuselage, communication of the cellular/PDA devices can be prevented with a lesser degree of noise floor lifting within the aircraft, thus reducing the chance of interference with terrestrial wireless access points and/or interference with important navigation or avionics subsystems within the aircraft.

摘要： Disclosed is a sound masking system including an airflow unit housing at least one speaker generating a masking sound field. The airflow unit is often an air diffuser set into a conventional suspended ceiling comprised of ceiling tiles. The air diffuser provides an acoustic hole in the ceiling plane whereby sound can travel into the room unencumbered by the plane of ceiling tiles. The speaker is housed within the air diffuser and is directed into the room to be treated. The speaker is capable of producing sound waves in a frequency that masks the human voice.

摘要： The present invention provides an apparatus for protecting an electronic apparatus against the transmission of radio waves from a nearby mobile communication apparatus. The apparatus comprises a plurality of radio wave generators for generating inhibiting waves transmitted to the mobile communication apparatus in order to block transmissions from the same. The invention further includes means for sweeping the frequency of the plurality of radio wave generators in different frequency ranges adjusted to cover all frequency ranges of the communication apparatuses.
