Abstract: A system to provide foot protection against anti-personnel land mines is designed for use by mine clearance personnel and includes a raised frame having a central foot support location thereon which ensures a spacing of the wearer's foot above the ground surface of from 10 to 30 cm. The ground-engaging parts of the frame are spaced forwardly and rearwardly of the foot location and the frame includes on its underside blast protection material, the combined results of these measures being to greatly attenuate the blast and fragmentation effects of an exploding mine on the foot of the user. Moreover, the underside of the structure, including legs, is aerodynamically shaped to deflect the blast wave loading and fragments generated by the mine detonation.

Abstract: A computer case having at least one 31/2" drive housing which can be removably mounted within the case. Each 31/2" drive housing has one or more (typically, two) channels. A 31/2" drive is slidably insertable within each channel. A plurality (normally, as many as four) 31/2 drive housings are removably mountable at different locations within the case via quick release connectors provided at different locations within the case. A "U" shaped mounting bracket captures each 31/2" drive. The bracket has two opposed legs, with one or more inwardly projecting pins on each leg. The pins slide into apertures located in the opposed sides of industry standard 31/2" drives. A one-piece backplane with quick release connectors is easily removed and replaced by adjacent a cutout provided in an outer wall of the case. A series of cutouts are provided in the backplane. Each cutout is positioned to align with a connector on a motherboard mounted in the case, when the backplane is in place adjacent the case outer wall cutout.

Abstract: A weighing scale comprising a housing having an upper platform for receiving a load, and a base; a lever assembly comprising a plurality of levers, each of which is in operative contact with the upper platform and supported by a post element mounted on the base. A cantilever beam is mounted on the base and positioned between the lever assembly and the base. A weight-transmitting pin is provided for supporting the lever assembly and acting on the cantilever beam for transmitting the load from the intermediate cover to the cantilever beam through the lever assembly. A strain gauge element is fixed on the cantilever beam for converting a strain developed therein into an electrical signal.
