Abstract
Official abstract text for this publication.
A method of estimating the time and flight of an acoustic signal transmitted by a transmit acoustic transducer determines a difference in time between receiving the transmitted acoustic signal and receiving an electromagnetic wave transmitted by the transmit acoustic transducer coincident with transmitting the acoustic signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method, comprising: providing a drive electrical signal to a piezoelectric bulk or microelectromechanical system (MEMS) transmit acoustic transducer in a transmit device; in response to the drive electrical signal, coincidently transmitting both an electromagnetic wave and an acoustic signal from the piezoelectric bulk or MEMS transmit acoustic transducer; receiving the electromagnetic wave at a receive acoustic transducer of a piezoelectric bulk…
