Patent ID: 7676246

Claim:
A first secure audio-visual communication device comprising: a device housing; a radio-frequency transceiver configured for sending a broadcasted audio data transmission simultaneously and in conjunction with a broadcasted visual data transmission; an antenna electronically coupled to the transceiver; a digital signal processor interfaced with the antenna through the transceiver and configured for storing a memory; a LCD module having an integrated memory and coupled to the transceiver for outputting visual data; an image sensor coupled to the LCD module and the transceiver for inputting visual data, and wherein the image sensor is pivotally engaged with the device housing; a speaker coupled to the transceiver for outputting audio data; a microphone coupled to the transceiver for inputting audio data; and a pre-amplifier configured such that a signal transmitted from the microphone is filtered and amplified by the pre-amplifier before reaching the digital signal processor; whereby the secure audio-visual communication device is a first wireless communication device and is configured for operating in a “secure” mode, wherein the transmissions broadcasted by the first wireless communication device are directly received in real time only by the at least a second and a third other secure audio-visual communication device within range that have each been pre-approved to receive said transmissions by registering said the second and the third other secure audio-visual communication device by adding a serial number associated with each of the second and the third other secure audio-visual communication device to a common list contained within the first wireless communication device, and wherein the transmissions broadcasted by the at least the second secure audio-visual communication device and the third secure audio-visual communication device within range are directly received in real time only by the first wireless communication device that have been pre-approved to receive said transmissions by registering each of the second secure audio-visual communication device and the third secure audio-visual communication device by adding their respective serial numbers to the common list contained within the first wireless communication device, whereby communications can proceed by at least one of a first case where the first, second and third secure audio-visual communication device are in communication with each other, and a second case where the one of the first, second, and third secure audio-visual communication device can be in communication with the other two of the first, second and third secure audio-visual communication devices which are not in communication with each other.
