  • Patent number: 6215380
    Abstract: An electromagnetic relay is designed so that it can be manufactured inexpensively and is based on a small unit size. The relay has a base group and a magnet system, it being possible to manufacture these separately and join them together as preassembled modular units. The base group has a base plate in which a component having a component wire is fixed in position. The magnet system has two flat pins each of which has a hole with a sharpened edge. When the magnet system is joined together with the base group, the flat pins are pushed into the base plate, in each case the edge at the wire component forming a contact created by an insulation displacement connection. The relay is preferably used in the automotive industry, especially if installation conditions are cramped.

  • Patent number: 5218339
    Abstract: An arrangement monitors a consumer in combination with an internal combustion engine or motor vehicle especially for monitoring an electric drive which is driven by an output stage in the form of a bridge circuit. Potentials are compared in the area of the consumer or of the output stage to pregiven threshold values derived from the normal operation. From this comparison, an alarm signal is generated in a time-delayed manner with the time delay being dependent upon the magnitude of the drive signal.

  • Patent number: 4793277
    Abstract: A tire pressure detector for motor vehicles which is to be fastened to a wheel rim comprises a pressure switch actuated by the air pressure in the tire for monitoring the tire pressure. The pressure switch includes a reference pressure chamber with an electrically conductive switching diaphragm which closes the chamber toward the tire and which cooperates with a contact pin of the reference pressure chamber and an electric oscillating circuit connected to the latter in the detector housing. The reference pressure chamber (23) is axially clamped between a supporting ring and a spacing ring of insulating material in the metallic detector housing by a radial collar, which is formed, so that an annular gap is formed between the collar and the inner wall of the detector housing.

  • Patent number: 4768375
    Abstract: In a pressure sensor for detecting the air pressure in the interior of tubeless tires of motor vehicles, on a rim having two edge beads extending around its outside and a drum-like base, to facilitate mounting and provide malfunction-free, exact detection of pressure it is provided that the pressure sensor (10) is disposed in a bore (9) of the preferably radially inner section (5) of a bead (3), and in particular the longitudinal axis (43) of the pressure sensor (10) forms an acute angle with the axis (44) of the rim.

  • Patent number: 4378769
    Abstract: In an ignition system for an internal combustion engine, a digital system for computing the timing advance is provided. Constants approximating the curve of timing advance v. engine speed are stored in a microprocessor. The positive half waves of primary current in the magneto generate the ignition energy and also generate a reference signal for controlling the actual ignition time. The sequence of reference signals is also used to generate a digital value indicative of engine speed. The latter is used to address the read only memory in which the constants for approximating the timing advance curve are stored. After each reference signal, the value read out from the read only memory is counted down by a counter. When the counter reaches the value of zero, ignition is started.

  • Patent number: 4327687
    Abstract: A disk mounted on a rotating shaft of an internal combustion engine has a signal generating segment which causes generation of a pickup signal having a leading and a trailing edge. The two different edges control different processes, as for example ignition processes of different ignition coils, fuel injection processes, or ignition processes during normal and starting operation. A basic counting value is counted down between two sequential edge signals in a counter. This is a speed-dependent value from which different countdown values for the next cycle are computed. To allow adjustment of the angle at which one process takes place without simultaneous adjustment of the angle at which the other process takes place, one or both of the edges of the segment from which the control signals are derived have slanted portions, so that movement of the pickup relative to the slanted portions will effectively cause a change in the angle at which a process is initiated.

  • Patent number: 4298930
    Abstract: In order to permit alternate transfer of different sets of data to a microprocessor over the same input/output lines, a coupling-decoupling circuit includes series-connected diodes and inverters. The input/output lines are coupled to a diode matrix which is scanned line-by-line and determines the transfer of a set of primary data in a first time interval during which the admission of supplementary data from secondary data lines is blocked. In a second time interval, the rows of the diode matrix are all placed in the same logical state while the supplementary data is admitted by the coupling-decoupling circuit to the same input/output lines which received the primary data.

  • Patent number: 4287565
    Abstract: To supervise a program controlled device which is subject to stray noise or disturbance pulses, particularly microprocessor controlled automotive vehicle electronic systems, a timing circuit is provided responsive to check pulses added to the program and defining a timing interval, the monitoring system distinguishing between disturbance pulses and static defects by supervising the control pulses and, upon failure of the control pulses, generating a program restart or interrupt signal, respectively, which both initiate a new start of the program cycle or, respectively, define a timing interval which, upon failure to sense further control pulses, initiates energization of an emergency switching system. Continuous failure to receive control pulses also can initiate the emergency switching system.

  • Patent number: 4267810
    Abstract: In order to permit a simplification of the crankshaft rotation sensor device which provides the computer of the control system with angular speed and position information for ignition and/or fuel injection timing, a signal generated by one pickup for every two engine cylinders from a single reference mark on the crankshaft is formed into a signal pulse which is used to trigger the counting of clock pulses from a clock into a counter. These are then periodically transferred to a computer as a numerical signal which represents the required information. In a first mode the counts are transferred every other period between pulses and the counter counts in the cycle periods between the pulses in which the counter is not transferring to the computer. In a second mode, the counter counts every cycle between pulses and the counts are transferred during every pulse itself.

  • Patent number: 3964461
    Abstract: An additional diode is provided in series with the charging diode through which the storage capacitor of a magneto ignition system is charged and the shutdown switch for the engine is connected between the common connection of the two diodes and the common connection of the magneto generator, and the capacitor diodes, because of their high back resistance, prevent any high positive or negative voltages from appearing across an open shutdown switch.
