    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: A protective arrangement for an electromagnetic load is disclosed. In this protective arrangement, the load and a control transistor form a series circuit from the battery voltage to ground and a series circuit of a free-wheeling transistor and a free-wheeling diode is connected in parallel with the load. By coupling the base of the free-wheeling transistor to ground, this transistor is made continuously conductive provided that the polarity of the supply voltage is correct, whereas, this free-wheeling transistor blocks if the supply voltage polarity is incorrect. This assures that none of the components is in danger of being destroyed in the event that the polarity of the supply voltage is incorrect.

    摘要: The motor is serially connected with a diode and a sensing resistor so that half waves of one polarity, for example negative, can flow through the motor and provide, across the resistor, a voltage drop corresponding to loading placed on the motor. A thyristor is connected in parallel to the diode and reversely poled to conduct the other half wave, then the positive, if triggered. Triggering of the thyristor is controlled by the voltage drop across the sensing resistor so that, under no-load conditions, only the negative half waves will be applied to the motor, thus limiting its no-load speed but, as loading is placed thereon, increasing portions of the positive half waves are likewise passed through the motor. The diode may, itself, be a controlled diode such as a thyristor which is rendered conductive by a phase control network, thus providing speed control for the motor, controlling actually only the negative half wave but, due to sensing resistor, effectively, regulating the motor current during both half waves. The circuit uses a capacitor which is charged to the voltage forming the control voltage on the thyristor conducting the positive half wave.

    摘要: A system and method of scheduling radio resources for a plurality of users in a packet-switched radio communication network. A scheduling number (Si) is calculated for each user before each scheduling event. A weight (Wi) is assigned to each user based on an associated Quality of Service. The Si varies depending on the assigned Wi and when the user entered the scheduling session. Radio resources are assigned to the user having the largest ratio Wi/Si between the weight and the scheduling number.
