DEFINITION

Classification: 340/825.79

Matrix:

(under subclass 825) Subject matter drawn to a two or more dimensional array of electrical elements in a receiver for distinguishing different control signals, and not elsewhere classifiable.

(1) Note. Switching systems including nonlinear saturable reactor (e.g., magnetic core) switching are classified in Class 307, subclasses 401+.

(2) Note. Information storage systems including nonlinear saturable reactors (e.g., magnetic cores) are classified in Class 365, subclasses 129+.
