DEFINITION

Classification: 73/596

Beamed:

(under subclass 584) Subject matter wherein (1) the sonic waves are in the form of beamed or directed waves or (2) the beamed waves sensed emanate from within or reflect from the surface of the body.

(1) Note. While the production of a beamed wave is not limited to the ultrasonic range, frequencies are generally in the ultrasonic range above 25 kHz as in the detection of typically sized discontinuities or flaws. The beam pattern is a function of the ratio of wavelength employed to the distance across the face of the transducer.

(2) Note. Where some means is provided for confining the wave, as a duct, the wave is considered to be a directed wave for the purposes of this subclass.
