Patent ID: 7529304

Claim:
A data transmission system comprising: a serial A/D converter having an analog input port, a sync port and a data out port whereby said sync port is capable of providing a sync signal, said serial A/D converter receiving analog data from a data source and providing serial digitized data; a transmission processor joined to control said serial A/D converter, said transmission processor providing a start command to cause said serial A/D converter to provide the sync signal; a first transmitter having a data in port joined to said serial A/D converter sync port to transmit any provided sync signal, said first transmitter further having an RF out port capable of transmitting radio signals at a first frequency; a second transmitter having a data in port joined said serial A/D converter data out port to transmit any provided digitized data, said second transmitter further having an RF out port capable of transmitting radio signals at a second frequency; a transmission antenna capable of transmitting radio signals at said first frequency and said second frequency joined to said first transmitter RF out port and said second transmitter RF out port; a reception antenna capable of receiving radio signals at said first frequency and said second frequency; a first receiver joined to said reception antenna and capable of receiving said first frequency signals and providing an output; a second receiver joined to said reception antenna and capable of receiving said second frequency signals and providing an output; a reception processor having an interrupt port joined to said first receiver output, said reception processor having output ports capable of providing commands on reception of a signal at the interrupt port; and a digital to analog converter having a data in port joined to said second receiver output, and further having input ports joined to said reception processor output ports for receiving commands from said reception processor, said digital to analog converter providing an analog signal at an analog out port representative of said digitized data received at said data in port.
