Patent ID: 7039362

Claim:
A wireless transceiver for performing ultrasonic measurements, said wireless transceiver comprising: an uplink transmitter configured to transmit at least one modulated timing pulse signal, each modulated timing pulse signal being transmitted over a respective uplink wireless channel, wherein the modulated timing pulse signal comprises a timing pulse signal modulated using an uplink carrier signal; at least one uplink receiver, each uplink receiver being adapted to receive a respective one of the modulated timing pulse signals from said uplink transmitter and being configured to supply an unmodulated timing pulse signal to a respective transducer; at least one downlink transmitter, each downlink transmitter being adapted to receive an echo signal from the respective transducer, and being configured to extract envelope information from the echo signal and to transmit a modulated echo signal over a respective downlink wireless channel, wherein the modulated echo signal is modulated using a downlink carrier signal; and a downlink receiver adapted to receive the modulated echo signals, each modulated echo signal being received from said respective downlink transmitter.
