DEFINITION

Classification: 340/286.01

SYSTEMS:

(under the class definition) Subject matter relating to a system including transmitter and receiver for signaling and/or indicating.

(1) Note. This is the miscellaneous subclass for systems of signaling and/or indicating and their subcombinations, not elsewhere provided for.

(2) Note. The terms signaling and indicating each denote production of a humanly perceptible signal.

(3) Note. Consult the search notes to the class definitions for some of the numerous other classes which contain signaling or indicating systems.
