摘要: An improved self-powered vehicle detector (SPVD) uses a two-axis magnetomr to sense a vehicle's magnetic signature and then telemeter vehicle presence information to a roadside receiver. The SPVD system includes digital nulling loops to cancel D.C. offset changes in the magnetometic output, a multi-tone code transmitter to transmit vehicle presence and SPVD condition signal, and an omnidirectional microstrip antenna to simplify installation and maintenance of the SPVD.

摘要: A liquid crystal display panel having a backlight for providing high brigess, uniformity of illumination intensity, high efficiency, and long battery life, and which can be manufactured at a low cost. The display device includes a liquid crystal display panel, a light source for illuminating the liquid crystal panel, a light passage member which can be formed of a transparent material disposed between the liquid crystal panel and the light source. The light source inlet side of the light passage member is formed with a recess with the thickness being reduced at the region diametrically opposed to the light source. A light reflecting member reflects light from the light source. Within the photoconductor, two or more of the wedged shaped photo conductor can be used for increased area of coverage.

摘要: A method and device for eliminating torsion during the servicing of cable heads. The device is a tool with a handle portion and clamping members having an opening and gripping surfaces for receiving and gripping two different cable-heads for servicing, such as attachment or detachment. When the handle portion is squeezed and held, the tool provides a compression force substantially parallel to a common central axis of the cable heads. The arrangement of the tool prevents undesired load on the cable heads, optimizes the efficiency of servicing while preventing damage to the cable-heads.
