DEFINITION

Classification: 315/149

(under the class definition) Systems wherein the system includes means for controlling the operation of the load device by means of radiant energy.

(1) Note. The load device may be a radiant energy sensitive device, that is, a load device whose operation is altered when subjected to radiant energy, or the system may include a radiant energy sensitive device, such as a photocell, which controls the operation of the load device when subjected to radiant energy.

(2) Note. The term "radiant energy" as used in this subclass and the indented subclasses includes radiant energy of any type, such as X-ray, light rays whether within the visible spectrum or not, Herztian waves and other radiated electrical energy, and emanations from radio-active substances.
