DEFINITION

Classification: 73/769

Coupling circuit for specific additional purpose (e.g., noise suppression) or having specified structure:

(under subclass 763) Subject matter having circuitry (a) for a purpose additional to, or perfecting, the transmission of the signal between the sensor and indicator or (b) in which the details of such circuitry are particularly described.

(1) Note. Mere naming of the circuit connection (e.g., conductor, bridge) is not, of itself, sufficient for classification herein.
