Classification: CPC B  F | IPC F

Claim 19:
20. 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 movement of the movable shutter elements is a translating motion along an axis normal to the thermally conductive base layer, to create movement towards and away from the thermally emissive surface of the thermally conductive base layer.
