Abstract: A portable system (20) for testing an electro-optical guidance assembly (22) includes an electro-optical test unit (40) with at least two sources of electromagnetic energy at different wavelengths for selectively illuminating the guidance assembly. The electro-optical test unit (40) is mounted within a frame (56) that can be part of a wheeled cart (50). The system (20) further includes one or more of: an adjustable fixture (84) for supporting a guidance assembly (22) for testing, a processor unit (42) for controlling the electro-optical test unit (40), a power supply unit (44) for providing electrical power to the electro-optical test unit (40) and the guidance assembly (22), and a leak test unit (46) for generating a vacuum in the guidance assembly (22) or for pressurizing the guidance assembly (22) with an inert gas to test for leaks.

Abstract: A linker is described and the method of forming an executable program from object code modules using the linker. The linker uses a linker control language in the form of an ordered sequence of relaxation instructions. The relaxation instructions include a jump relaxation instruction which specifies the instruction count of the relaxation instruction which is subsequently read. In this way, more flexibility can be provided for linkers.

Abstract: The position of a monitored door is detected via a magnetic sensor. The detected positional information is digitally encoded and transmitted across power grid wiring within the home to at least one receiver. Based in part on the received positional information, a door alert indicator is activated. The system for door alert is also capable of monitoring multiple door or window openings via a network of interconnected sensors designed specifically for garages. Multiple door alert indicators may be placed throughout the home without interfering with the door status indicator system.

Abstract: Most gaseous ion lasers run with continuous drive and operate under steady state thermal conditions. They cannot be driven according to the needs of the application, and their kilowatts of waste heat must be removed from the working environment. A fast transient effect, ion loss to the wall of the bore, is dealt with by pre-saturating the wall during novel bore-conditioning pulses applied at startup. Additional improvements provide denser gas during this step, otherwise only small bore tubes could be presaturated. Other improvements provide means for overcoming the transient effect of discharge gas pumping. And a thermal thinning of the column gas is avoided by means of a novel gas density regulation. The result is a switched, dynamically operating gas laser, whose drive can follow the peak needs of the application while its waste heat is averaged to a low output level acceptable in the working environment.
