(under subclass 294) Systems, wherein the regulation of the current or potential supplied to the load device is automatically controlled in response to some condition.
(1) Note. The condition controlling the regulation may be the current or potential of the load device circuit, some condition, such as the temperature, of the load device, or the temperature of the atmosphere in which the load device operates or any other condition affecting the operation of the load device.
