DefinitionThis is the residual class for the communication of information or intelligence in the form of travelling stresses in an elastic medium which are detected or generated by electric signal handling means wherein the electric signal represents the communicated information or intelligence. This class provides for subject matter not classifiable elsewhere comprising combinations of acoustic wave transmitters, receivers, and electric signal processors as well as electrical acoustic wave transmitters, receivers, and signal processors, per se, and subcombinations of such devices whose proximate functions are limited to use in acoustic wave communications. |
