DEFINITION

Classification: 126/572

With control means energized in response to actuator stimulated by condition sensor:

(under subclass 569) Apparatus having a device for sensing ambient condition, condition within the converting means, or sensing a condition of a fluent medium as it passes into, through, or from the converting means and operates to affect the fluent in some manner (e.g., as by affecting its flow, pressure, or temperature) or to operate a structure to block or permit more or less of the available solar radiation to reach the converting means or to move the converting means depending on the position of the sun.
