Classification: CPC B  F | IPC F

Claim 18:
19. A thermal emissivity control system, comprising:
a segmented array including:
a thermally conductive base layer configured to be connectable to an external heat generating subsystem, the base layer including a thermally emissive surface;
a plurality of actuation elements at least one of:
positioned on the base layer; or
disposed adjacent to the thermally emissive surface of the base layer;

a plurality of movable shutter elements disposed adjacent one another in a grid pattern, and controlled in movement by the actuation elements to create gaps of controllably varying dimension therebetween, to control at least one of a magnitude of thermal radiation through the gaps or a direction of emission of the thermal radiation through the gaps; and

wherein at least one of the actuation elements enables rotational movement of an associated one of the movable shutter elements, the rotational movement being about an axis normal to the thermally conductive base layer.
