  • Patent number: 6552531
    Abstract: The present invention relates to a method and a circuit arrangement for processing signals for an active motion sensor which generates at least one first sequence of input pulses that contain motion information. By at least one integrating filter circuit, each input pulse of a pulse train is integrated, and an associated output pulse is generated during a period in which the integrated signal is in excess of a predeterminable second threshold value after a predeterminable first threshold value has been exceeded so that the output pulse has a time delay with respect to the input pulse. As a result, noises of a duration which is shorter than the delay time are effectively suppressed.

  • Patent number: 6313617
    Abstract: The present invention relates to a method and apparatus for reducing voltage sags in the battery supply lines of the circuit arrangement which is used to regulate or control the current input of a consumer in an automotive vehicle, wherein the consumer current is regulated or controlled by pulse-width modulation (PWM) and a controllable switch is used. To this end, a circuit is used which influences the edges of a pulse-width modulated signal, and a signal representative of the rate of change in the current in the battery supply lines to the consumer is produced. This signal is fed back to the input signal by way of a capacitor.

  • Patent number: 6226164
    Abstract: A circuit configuration for actuating active- and/or passive-operated warning signal generators or warning lamps (WL1, WL2) comprises an integrated circuit (IC1) having individual actuating steps (1,2) and connections for the individual warning signal generators. Moreover, an adapter connection (WLCON) is provided which upon connection to chassis configures the circuit (IC1) for the actuation of two passive warning lamps (Wlp) or other warning signal generators, permitting upon connection to an ohmic resistance (R) leading to chassis, actuation of an active (Wla) and a passive (Wlp) warning signal generator and configuring—if left open—the circuit (IC1) for actuating two active warning signal generators (Wla).

  • Patent number: 6208242
    Abstract: The present invention relates to a circuit arrangement to monitor a regulated output voltage in an automotive vehicle, wherein the regulated output voltage is monitored as to whether defined threshold values have been exceeded and/or have fallen short of, wherein the circuit element for regulating the output voltage and the circuit element to monitor whether threshold values have been exceeded or have fallen short of are integrated in one chip, wherein the adjustment of the output voltage is effected by way of a first reference voltage, and wherein monitoring of the threshold values as to whether they have been exceeded or have fallen short of is conducted by way of a second reference voltage.

  • Patent number: 6127830
    Abstract: In a method of monitoring an output module to which a number of inductive loads are connected and in which the current flowing through these inductive loads is regulated by clocked driving of the output stages, the current created in the blocked phases of the output stages by the inductively stored energy is partially or temporarily conducted across a common current measuring device and evaluated for testing the output stages, including the inductive loads.

  • Patent number: 6115832
    Abstract: To monitor a data processing circuit which includes two (or a plurality of) microprocessors or other data processing systems which are mounted on a joint chip and connected by data lines, the microprocessors jointly produce data words which form a data word sequence and are transmitted to a monitoring circuit at predetermined times. The monitoring circuit is arranged on a separate chip. The data words of the data word sequence are checked by the monitoring circuit with respect to the contents and time of appearance of the individual data words. It is favorable to make up the individual data words of partwords which are produced according to different algorithms.

  • Patent number: 5909348
    Abstract: A circuitry for detecting a fault current or leakage current on the supply line of an electronic circuit includes a current source which is rated for a maximum allowed fault current or leakage current. The current source is fed by an auxiliary voltage source. The potential on the supply line which prevails when the supply voltage is disconnected due to the leakage current is determined and assessed by a potential monitor.

  • Patent number: 5631626
    Abstract: A circuit for triggering warning lamps including a self-conductive transistor circuit with a triggering circuit connected to the supply voltages. The triggering circuit keeps the transistor circuit blocked if the supply voltages are proper. If voltage fails, the transistors of the self-conductive transistor circuit open a current path from the warning lamp terminal to the control terminal of the power driver which results in switching on of the power driver and, thus, of the warning lamp.

  • Patent number: 5614798
    Abstract: A circuit configuration for the control of a servomotor (M) with the aid of current pulses supplied by a current-controlled final stage (1) of a control system. The pattern of current rise is analyzed after actuation of the final stage (1) for identifying a short circuit in the servomotor (M) across the power supply system (+U.sub.B). An excessively high current (I.sub.K), after a measuring period (T.sub.M), commencing after the transistor (LT) of the final stage (1) has been placed in saturated state, is indicative of a short circuit.

  • Patent number: 5327056
    Abstract: A circuit configuration for limiting the cutoff voltage occurring in controlling a servomotor (M) by means of width-modulated DC pulses comprises a power transistor (T2) which, via a capacitor (C) is connected through for a short time when a cutoff voltage appears thus limiting the cutoff voltage. Subsequently the transistor (T2) presents a high impedance. As a result a short-circuiting of the servomotor (M) will be prevented in the phase in which a spring force resets the servomotor into its zero position.
