Abstract: An apparatus for contactless data and energy transmission includes a stationary part having at least one coil for data and energy transmission, and an oscillator connected to the at least one coil for energy transmission. A movable part has at least one coil for data and energy transmission, at least one rectifier device connected downstream of the at least one coil, and at least one charge capacitor connected to the at least one rectifier device for carrying a pulsating operating voltage. One pair of the coils is used for energy transmission and one pair of the coils is used for data transmission. The coils of the movable part are arbitrarily associated with the coils of the stationary part. A device is disposed in the movable part for transmitting data from the movable part to the stationary part, by returning a portion of energy received through an applicable one of the coils of the movable part, modulated in accordance with a data signal, through another of the coils of the movable part.

Abstract: A fuel supply control method for electronically controlling the fuel supply to an internal combustion engine equipped with a supercharger. Pressure in the intake passage downstream of a throttle valve arranged therein is detected by first and second pressure sensor means, whereas a plurality of predetermined values of basic fuel quantity are stored in each of first and second storage means corresponding, respectively, to the first and second pressure sensor means, which are functions of the intake passage pressure and the engine rpm.
