Claim Text:
1. An ultrasonic transducer drive, comprising: a signal generator for producing an outgoing signal; a transducer for converting said outgoing signal to outgoing ultrasound and for converting at least a portion of reflected ultrasound to an incoming signal, said transducer having a transmit side and a receive side; said transmit side connected conductably to said signal generator during a first predetermined period of time; said receive side connected conductably to a signal receiver during a second predetermined period of time; and a shunt connectable between said receive side and a first reference potential; wherein said signal generator is configured to generate said outgoing signal during said first predetermined period of time while said shunt is configured to connect said receive side to said first reference potential during said first predetermined period of time; wherein said signal receiver is configured to receive said incoming signal during said second predetermined period of time while said shunt is configured to be open during said second predetermined period of time and while said transmit side is configured to connect to a second reference potential during said second predetermined period of time; wherein said receive side is connected operably to a receive switch; wherein said receive switch is connectable switchably to said signal receiver; and wherein said receive switch is configured to connect said receive side to said signal receiver for said second predetermined period of time; wherein said transmit side is connected operably to a transmit switch; wherein said transmit switch is connectable switchably to said signal generator and to said second reference potential; wherein said transmit switch is configured to connect said transmit side to said signal generator for said first predetermined period of time and said transmit switch is configured to connect said transmit side to said second reference potential for said second predetermined period of time; wherein said reflected ultrasound is elicited by said outgoing ultrasound; and wherein said receive side is conductively isolated from said transmit side.
