Abstract: A compressed air distribution and battery recharger is provided in a tool bar handle for a tool cabinet. The tool cabinet handle provides outlets for compressed air which is regulated, dried and lubricated for use with pneumatic tools along with a battery charger for recharging power packs for portable electric tools.

Abstract: A simple and inexpensive method for using aerial or satellite photographs of an area of terrain to form images to be used in the simulation of a series of synthetic aperture radar (SAR) images of the terrain as would be observed by a down-looking SAR mounted on an aircraft over the terrain. Scanned and digitized photographic pixels are formed and converted into radar image pixels and combined into composite images as required for SAR simulation. Terrain elevation data are assembled, correlated with the radar image pixels and converted to elevation images. These images are stored on media accessible by aircraft simulators and correlated with simulated aircraft position and altitude data to form composite images with obscured terrain features for display as darkened areas closely duplicating actual SAR images when displayed in an aircraft simulator.
