Abstract: A bar is designed for attaching a steering cylinder of a vehicle to a wheel axle. The bar is twisted around its longitudinal axis. The bar is manufactured by cutting out a rectangular plate of metallic material or of composite material, clamping the longitudinal ends of the cut-out plate, and pivoting one end or pivoting both ends in opposite directions, around a longitudinal axis of the plate.

Abstract: A system of digitally controlling light output by producing separate control signals for different colors of light. The light is contained in an optical waveguide, either prior to shaping or after shaping. Each of the control signals is coupled to a digitally controlled device which controls the shape of the light output. The digital controlling device can be digital mirror devices, for example.

Abstract: An orientation-adjusting device for a vehicle head light comprises a housing encasement, an active unit, a driven unit, a cover, and driven screw rod, an elastic unit, and an elastic sealing unit. The housing encasement is installed with an elliptical hole and an axial hole. The active unit has an axial portion axially installed to the axial hole, and a gear portion located in the housing encasement. The driven unit is installed with a gear portion engaged with the gear portion of the action unit, and an axially-formed penetrating hole, which includes a threaded hole section near the active unit and a threadless hole section remotely away from the active unit. The cover is installed on the housing encasement to cover the interior of the housing encasement for preventing the driven unit from projecting out from the housing encasement.

Abstract: The present invention relates to a method and apparatus for generating, displaying and transmitting next-in-time from a first recording truck to a second recording truck to thereby provide coordination of operations between trucks.
