Abstract: A flexible inflatable hinge includes curable resin for rigidly positioning panels of solar cells about the hinge in which wrap around contacts and flex circuits are disposed for routing power from the solar cells to the power bus further used for grounding the hinge. An indium tin oxide and magnesium fluoride coating is used to prevent static discharge while being transparent to ultraviolet light that cures the embedded resin after deployment for rigidizing the inflatable hinge.

Abstract: Multiple layers of a clear insulating material, such as clear polyimide, with horizontal metalization layers therebetween and with vertical feed through metal traces therethrough form a flexible three dimension circuit printed circuit board upon which semiconductor devices, such as thin film solar cell can be directly deposited for forming a flexible electronic module, and upon which electronic discrete component can be bonded and electrically connected. In one exemplar configuration, a flexible thin film solar cell power module has thin film solar cells deposited on one side and power converters bonded on the other for a solar array power system. The flexible printed circuit board is well suited for forming electronic systems about a curved surface such as a power sphere nanosatellite.

Abstract: [2,2,2-Trifluoro-1-(trifluoromethyl)]ethylidene-bisbenzenethiols are new compounds useful as precursors in the manufacture of polysulfide polymers and copolymers.

Abstract: Acetylene terminated s-triazine oligomers are disclosed which polymerize into stable high temperature resins. The oligomers of this invention are readily prepared from off-the-shelf starting materials, they are soluble in conventional low boiling solvents and exhibit low melting points which facilitate ease of processing.
