摘要： The invention is directed to an arrangement for controlling a fuel metering apparatus controlled by a microprocessor and supplemented with an emergency control system. In the event of a microprocessor failure due to a defect, the system attempts to restart the microprocessor. At the same time, an emergency operation pulse generator assumes control of the fuel metering apparatus. Such an emergency control system is particularly suited for fuel metering apparatus which serve to control internal combustion engines for motor vehicles.

摘要： Disclosed are a method and a device for indicating the malfunction of an apparatus for generating injection control pulses for a fuel injection system. The method compares relatively narrow trigger pulses derived from ignition pulses with the fuel injection control pulses. When the injection control pulses coincide with the trigger pulses, no indication is present. Only when an injection control pulse is missing does the trigger pulse prevail and trigger a bistable switching circuit which activates an optical or acoustical indicator.

摘要： Electronic control circuitry is provided for controlling the actuating current of electromagnetic devices and in particular of the electromagnetic fuel injection valves of an internal combustion engine. In order to program the magnitude of the actuating current from an initial high level to a lower maintenance level, there is provided a driver circuit which receives fuel injection control pulses from a fuel injection system, not itself part of the invention, and processes these control pulses into valve-actuating current pulses. The valve current is sensed by suitable transducer, for example a resistor, and the resulting signal is fed to a two-point controller which suitably alters the input to the driver circuit to thereby change the valve actuating current. The set-point value on which the two-point controller operates is itself subject to change by means of a suitable circuit. There is further provided a free-running circuit and a quenching circuit for reducing the voltage peaks resulting from the collapse of the magnetic fields stored in the valve actuating coils. Two embodiments are presented.

摘要： An arrangement for lighting a given straight section of a roadway having spaced-apart parallel curbs is disclosed herein and includes a luminaire positioned a substantial distance to one side of and above the roadway curbs. The luminaire includes a reflector, light source and a refractor which cooperate to effectively and efficiently light the given roadway section while, at the same time, minimizing the amount of light which spills onto opposite sides of the roadway curbs.

摘要： An arrangement for indirectly lighting a room by directly lighting the ceiling within the room is disclosed herein and includes a plurality of luminaires spaced from one another within the room. Each luminaire is spaced below the ceiling, preferably supported on the floor of the room in a readily mobile fashion, and directs light onto the ceiling both directly above it in the direction of zenith and at wide angles with zenith.
