Abstract: A printed circuit board can be used as a test card. The printed circuit board has a first image and a second image. The first image includes a first array pattern for attaching a package, a first power plane, and a first ground plane. The second image includes a second array pattern for attaching a package, a second power plane, and a second ground plane. A first routing area between the first image and the second image electrically and physically isolates the first power plane from the second power plane. The first routing area also physically isolates the first ground plane from the second ground plane. A first single trace extends through the first routing area. The first single trace electrically connects the first ground plane to the second ground plane.

Abstract: An improved configuration for a surgical laser instrument to provide the alternate contact cutting and no-contact coagulating of biological tissues by means of a fiber-optically guided irradiation of a laser is disclosed. This configuration includes instrumentation to enable discrimination between background illumination (i.e. xenon illumination scopes, room lights) and white light produced by the burning of tissue residue at the distal fiber tip. White light is described as a light having a wavelength between 0.3 to 0.9 mm. This improvement has the advantages of preventing background illumination from interfering with operation of a laser equipped with a white light feedback control device. Ultimately, this provides the surgeon with a more predictable laser delivery device which subsequently makes the laser safer to use.

Abstract: The present invention is directed to an adaptor for the conversion of laser connectors which will render a pre-existing laser system having an inside connector receptive to and connectable to an otherwise non-fitting generic or proprietary outside connector. This adaptor includes a locking sleeve and a captive sleeve located within the locking sleeve. The captive sleeve comprises of a pigtail attachment and a pre-existing laser system outside connector. The pigtail attachment has a forward end and a rearward end and is adapted to connect to a pre-existing laser system outside connector with extended fiber at its forward end and is adapted with connecting means for receiving a final outside connector different from the pre-existing laser system outside connector, at its rearward end. The pigtail attachment has locking means with a first position and a second position.

Abstract: The invention is a free standing engine tester that can be fabricated of el stock and vehicle parts available in forward military areas where it is used. The tester has a vehicle transmission and "final drive" power take off units mounted to a frame, and the final drive units contain braking mechanisms by which a load can be applied to the engine. The engine and transmission are mounted on a frame whose configuration and low center of gravity prevent engine torque from tipping the tester. A winch mounted to the frame has a hand operated crank by which a person using the tester can sufficiently tension a brake actuation cable engaged to the braking mechanisms so that a stall load can be applied to the engine.
