DEFINITION

Classification: 367/153

Plural transducer array:

(under subclass 141) Subject matter comprising a plurality of

transducers having electrically distinguishable inputs or outputs arranged in a definite spatial relationship with respect to one another.

(1) Note. A plurality of spatially arranged transducer elements having only one electrical output or input at which the effects of the individual elements are indistinguishable is considered to a unitary transducer and not an array of this subclass type.
