Abstract: An improved track-mounted movable target system is disclosed. Power is inductively transferred to a target carrier movable between first and second locations. The transferred power is used to power electrical equipment on board the target carrier. The electrical equipment may include electric motors, lights, solenoids, and control circuitry for the motors and solenoids. Preferred embodiments of the invention are implemented as track-based systems, as the track provides not only stability to the target carrier, but also protection from stray bullets to the conductive cable. For a first embodiment of the invention, power is transferred to a target carrier via a stationary inductor and a movable cable, which also provides motive force to the target carrier. For a second embodiment of the invention, power is transferred to a target carrier via a stationary cable and an inductor movable with the target carrier.

Abstract: This invention embodies an improved process for annealing integrated circuits to repair fabrication-induced damage. An integrated circuit is annealed in a pressurized sealed chamber in which a forming gas comprising hydrogen is present. Pressurization of the chamber reduces the contribution made by the final anneal step to total thermal exposure by increasing the diffusion rate of the hydrogen into the materials from which the integrated circuit is fabricated. Ideally, the forming gas contains, in addition to hydrogen, at least one other gas such as nitrogen or argon that will not react with hydrogen and, thus, reduce the danger of explosion. However, the integrated circuit may be annealed in an ambiance containing only hydrogen gas that is maintained at a pressure greater than ambient atmospheric pressure.

Abstract: A water purification system utilizes a radial filter and an ultraviolet lamp in a small, portable, countertop housing. A standpipe is positioned between the filter and the ultraviolet lamp to control the flow of water so that it flows along substantially the entire length of the UV lamp. The lamp is made integral with a quartz-tube covering and a threaded cap and connector to enable replacement of the UV lamp assembly. The housing encompassing the filter system is also easily disassembled to enable cleaning of the housing and replacement of the filter. A pressure vent is provided in the housing cover to equalize pressure and provide for a water level differential when the filter is disabled. A UV lamp indicator is included to show that the lamp is in operation.
