Abstract: A pump motor of a hydraulic hybrid system also serves as a pump to supply hydraulic oil or lubricating oil to a power train, thus enabling elimination of an oil pump provided in the power train and hence reductions in the number of parts and cost, and, in addition, an existing oil pan provided in the power train and the like are utilized for the hydraulic hybrid system, which in turn enables achieving further reductions in the number of parts and cost. Moreover, when idle-reduction control is performed on an engine, during engine's stopped conditions, the pump motor can be driven as a motor by hydraulic pressure accumulated in an accumulator to start the engine and supply the hydraulic pressure to a transmission, thus eliminating a need to provide a motor-driven oil pump for the idle-reduction control and hence enabling a further reduction in cost.

Abstract: Provided are a distance measuring device and a distance measuring method which can easily distinguish a reflected signal from a desired tag from an unnecessary wave so as to improve the distance measuring accuracy even when IR-UWB is used for measuring a distance. The method uses a reader ID indicated by a code string formed by P bits (P is a natural number) for identifying a base station and a tag ID indicated by a code string formed by Q bits (Q is a natural number) for identifying a radio terminal. The method generates a unique word containing P pulses, each of which is ON/OFF-modulated depending on whether each of P bits indicating the reader ID is 1 or 0. The method generates a frame containing 2 M unique words and a burst containing Q frames. The method further outputs a transmission signal containing a plurality of bursts. A radio terminal Amplitude Shift Keying (ASK)—modulates the transmission signal depending on whether each of the Q bits indicating the tag ID is 1 or 0.
