20120220227 | SYSTEM AND METHOD FOR COMMUNICATING BETWEEN NEAR FIELD COMMUNICATION DEVICES WITHIN A TARGET REGION USING NEAR FIELD COMMUNICATION - Systems and methods for communication between near field communication devices within a target communication region using near field magnetic induction is disclosed. One method comprises generating a near field detectable signal at an active node having a power level sufficient to enable communication with a plurality of near field communication nodes located within the target communication region. Information is modulated onto the near field detectable signal using at least one of the near field communication nodes. The modulated information is detected at the active node. The information is then relayed on the near field detectable signal from the active node to at least one of the plurality of near field communication nodes within the target communication region. | 08-30-2012 |
20090041241 | NEAR FIELD COMMUNICATIONS SYSTEM HAVING ENHANCED SECURITY - A near field communication system can include a near field generator configured to generate a near field detectable information signal. The near field generator and supporting circuitry also produces incidental electromagnetic radiation. A masking signal transmitter is used with the near field generator and radiates a masking electromagnetic signal. The masking electromagnetic signal may substantially mask the incidental electromagnetic radiation. | 02-12-2009 |
20090029743 | WIRELESS HEADSET AND MICROPHONE ASSEMBLY FOR COMMUNICATIONS DEVICE - Disclosed herein is a communications system implementing a microphone wirelessly connected to a half-duplex communications device, such as a two-way radio or a radio-simulating cellular phone. The microphone may incorporate a transmit/receive switch wherein a transmit signal is wirelessly transmitted from the microphone to the communications device to direct the communications device to enter into a transmit mode. The microphone may communicate with the half-duplex communications device through a magnetic induction link. | 01-29-2009 |
