摘要： An ultrasonic monitoring apparatus is provided for use by an operator in detecting ultrasonic vibrations and sound waves. The ultrasonic monitoring apparatus consists of a hand held device with a sensor socket that allows a variety of different types of sensors to be interchangeably installed in the hand held device. These sensors include both contact and airborne ultrasonic sensors as well as a combination temperature and ultrasonic sensor that allows the operator to simultaneously monitor the surface temperature of an object and the ultrasonic vibrations produced by the object. Identification information corresponding to the type of sensor is encoded on the individual sensors. The identification information is read by an identification circuit located in the hand held device. This identification information allows the hand held device to configure itself to operate with the type of sensor installed in the socket.

摘要： A laser light tachometer for measuring the rotational speed of a selected rotating body without making physical contact with that body. The laser technology art is used to provide a beam of light, visible even under extremely bright ambient light conditions, to be used to measure the rotational speed of a rotating device from greater distances than previously possible. A diverging beam of laser light is collimated and transmitted to a rotating body the RPM of which is to be measured. The rotating body modulates the beam and reflects it back to the tachometer where it is focused onto a photodetector, which converts it into an electrical signal representative of the speed of the rotating body. Provisions are made for direct digital readout and for supplying the signal to other devices.
