Omnidirectional Ultrasonic Location Sensor
IEEE Sensors, 2005., 2006Rapid construction of the human activity observation system at low cost is necessary with respect to research into human activities and commercialization. The authors have developed an ultrasonic 3D tag system that uses ultrasonic transmitters/receivers for observing human activities.

Ultrasonic sensor device and ultrasonic transducer
The Journal of the Acoustical Society of America, 2010An ultrasonic sensor device includes an ultrasonic transducer and a hollow case. The ultrasonic transducer includes a tubular housing having a bottom, a piezoelectric element and a vibrating surface. The piezoelectric element is fixed to an inner surface of the bottom of the tubular housing.

Ultrasonic sensor mounting device
The Journal of the Acoustical Society of America, 1995A device for mounting an ultrasonic transducer on user equipment for operation in a contaminating, ambient environment. A housing has a forwardly extending, profiled inner surface for promoting focusing along an axis of ultrasonic waves emitted by a transducer mounted against a shoulder of the casing.

Proceedings of IEEE Ultrasonics Symposium ULTSYM-94, 1994
Ultrasonic sensors in air are intelligent sensors, which use wave-propagation phenomena in air to measure physical or chemical variables. With accordance to the influence principle, two main types of ultrasonic sensors can be differentiated. Propagation-path sensors decode changes on propagation to obtain a fast measurement of temperature, pressure ...
