| 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 |

| 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 |
| 20090081943 | SYSTEM AND METHOD FOR NEAR FIELD COMMUNICATIONS HAVING LOCAL SECURITY - 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. | 03-26-2009 |
