Abstract: A boom structure is deployable from a collapsed, stowable configuration to an elongated truss configuration. The boom structure contains a plurality of truss-forming multi-sided bays. A bay contains a pair of battens joined together at corner regions by foldable longerons. A side of a bay has a plurality of diagonal cord members crossing one another and connected to diagonally opposed corner regions of the side. When the longerons are in their folded positions, the battens are nested together against one another in a stacked arrangement and the diagonal cord members flex into a compact stowed configuration between adjacent battens. The stowed battens are compressed to each other at their corners to form a stowed structure capable of reacting loads.

Abstract: A self-aligning release assembly for a separation mechanism is provided. The separation mechanism has a protective housing for selectively releasably securing a fastener. The protective housing is mountable to a structure. The release assembly comprises a rotatable flywheel having an internal bearing race with the bearing race having a plurality of recessed portions. A plurality of bearing elements contact the bearing race and a positioning element is positioned within and adjacent the flywheel for aligning and retaining the bearing elements. A retaining mechanism releasably retains the fastener with the retaining means positioned within the flywheel with the outer surfaces of the retaining means abutting the bearing elements.

Abstract: A battery bypass assembly for bypassing for bypassing a first battery cell electrically connected to a second battery cell. The battery bypass assembly has a first bypass contact and a second bypass contact. A voltage sensing mechanism is electrically connected between the first battery contact and the second battery contact for sensing a predetermined voltage loss. An expansive material within the housing expands upon the voltage sensing mechanism sensing a predetermined voltage loss. A plunger mechanism is moveable from a first position to a second position with a maintaining mechanism maintaining the plunger mechanism in the first position and moveable to allow the plunger mechanism to move into the second position. An actuating mechanism contacts the expansive material and the maintaining mechanism for moving the maintaining means upon expansion of the expansive material wherein the plunger mechanism, upon reaching the second position, bypasses the first battery cell.
