Abstract: A soluble polyimide polymer with tethered oligomeric silsesquioxane compounds is produced using efficient, gentle reactions. A carboxylic acid attachment point on the polymer backbone is used to connect the oligomeric silsesquioxane. The oligomeric silsesquioxane compound includes an amine or an alcohol on an organic tether, which reacts with the carboxylic acid attachment point to produce either an amide or an ester bond. The amide or ester bond includes a carbonyl carbon directly connected to a phenyl group in the polymer backbone. The resultant polyimide polymer has many beneficial properties.

Abstract: A target for use in photogrammetric analysis that does not distort the object to be analyzed has been developed. The target is formed by mixing a diffuse material with a solvent and then applying the mixture to the surface of the object to be analyzed. The object is then coated with a reflective material so that the diffuse material forms a reflective target suitable for use in photogrammetric analysis.

Abstract: One or more thin film battery cells are embedded in a multilayer thin film flexible circuit board supporting electronic devices, such as power regulators, for forming an integrated battery and circuit module. The module can be made using conventional thin film processes. The module is well suited for applications where size and space limitations, such as on spacecraft or credit cards, require the use of ultra thin power sources integrated with respective electronic devices and printed circuits.

Abstract: The invention is an inflatable antenna system. The antenna system includes an inflatable lenticular dish. The dish is enclosed in an inflatable radome. The inflatable radome stabilizes the orientation of the dish and protects it from environment conditions such as wind.
