Abstract
A sensor for ultrasonically measuring a portion of a structure, the sensor comprising: a transducer for converting an analog transmit signal to an ultrasonic transmit signal, and for converting an ultrasonic reflected signal to an analog reflected signal; a housing integrated with the transducer and containing at least: a processor; a wireless data transmitter for transmitting wirelessly a data signal from the processor; a transmit and receive circuit for transmitting an analog transmit signal to the transducer in response to a transmit trigger from the processor, and for receiving an analog reflected signal from the transducer; an A/D converter for digitizing only a portion of the analog reflected signal in response to a sample trigger from the processor; a battery to supply power to the processor, the wireless data transmitter, the transmit and receive circuit, and the A/D converter; memory operatively connected to the processor and configured to instruct the processor to execute the following steps: repeatedly triggering the transmit and receive circuit and the A/D converter to obtain a digitized composite signal through time-equivalent sampling; processing the digitized composi…
