  • Patent number: 6567476
    Abstract: The method of transmitting data as a sequence of high bits and low bits over a transmission line from a transmitting device to a receiving device includes transmitting synchronization signals over the transmission line and transmitting one and only one high bit or one and only one low bit over the transmission line at an end of each synchronization signal. When the predetermined voltage levels for the high bit, low bit and synchronization signals are different from each other, the method is implemented in an especially simple manner. The interfaces for the receiving and transmitting devices for performing the method are also described.

  • Patent number: 6555930
    Abstract: According to the invention, an apparatus for automatically detecting a motor vehicle's generator type is proposed, in which the characteristic voltage course is measured at a terminal (DF) of the generator (1) and compared with values stored in memory. Via an interface (3), a control unit (5) is connected to the controller (2) or generator (1) and evaluates the voltage change (&dgr;DF) upon a load change. To that end, the voltage at the terminal (DF) is measured and evaluated before the electrical load (8) is turned on, after it is turned, and after it is turned off. By means of this apparatus, advantageously not only the generator type (A, B) but also incorrect installations can be ascertained.

  • Patent number: 6522835
    Abstract: A lens-fitted photographic film package with dual lens includes a film-free self-activating shutter mechanism and a detachable cartridge for removing and installing film. A 35-mm film cartridge is attached to a cartridge adapter, and a filmstrip end is inserted and pre-wound into a winding housing including a winding spool therein. As photographs are taken, film is advanced frame-by-frame into the film cartridge, where it may be easily removed from the adapter without rewinding of the film, and replaced by a fresh film cartridge. Thus, the adapter transforms the lens-fitted photographic film package into a reusable package.

  • Publication number: 20010031026
    Abstract: Especially simple interfaces for outputting or receiving data are proposed, which can be operated by an especially simple method. It is provided that three different levels can be realized on the bus. One of these levels (V0) is used to generate a synchronization signal for the successive transmission of a high bit or a low bit. The individual bits are realized by means of the other two voltage levels (V2, V1). In a modification, via interfaces or connecting lines, items of information that are represented with the aid of two different levels are exchanged. In the process, by means of different pulse lengths, both synchronization pulses and two different information pulses are generated.

  • Patent number: 6218814
    Abstract: A device for voltage regulation for a generator driven by an internal combustion engine is described in which the voltage regulator is equipped with a load response travel function (LRF), which prevents a rapid rise in the exciting current when a powerful electric consumer is turned on. By means of a suitable trigger circuit which evaluates the engine rpm and thus the generator rpm, the load response travel function is blocked during travel when rpm values are falling, so that in this case, the voltage incursions that occur during an active load-response function are maximally averted.

  • Patent number: 5602470
    Abstract: In a circuit arrangement for measuring a starting of rotation of a generator having an exciting winding and three-phase windings, a voltage regulator regulates an output voltage of the generator by influencing an exciting current, the three-phase windings are connected to one another at a point, one of the phase windings is connected to ground via a first resistor, another of the phase windings is connected to ground via a second resistor, a voltage across the first resistor is evaluated as a rotational-speed-dependent alternating voltage, this voltage is compared with a threshold voltage, and the starting of the rotation of the generator is detected when the measured voltage exceeds the threshold voltage.

  • Patent number: 5594321
    Abstract: The battery charging apparatus includes a generator, main voltage regulator, an auxiliary voltage regulator, at least one consuming device and a protective circuit having circuit portions for recognizing and signalling faults via a charge control lamp. The generator output voltage is rectified with rectifier bridges containing Zener diodes. Voltage comparison to threshold values and logic circuitry for processing the comparison results are used to determine the presence of faults in the operation of the battery charging apparatus. The fault detection device detects conduction defects in the main voltage regulator and/or interruption in the generator excitation circuit. The logic circuitry determines whether simultaneously both a supplied voltage exceeds a threshold value and the main voltage regulator is turned on longer than a predetermined time interval to indicate its continuous operation.

  • Patent number: 5548202
    Abstract: In a device and a method for regulating an alternator increased alternator output is achieved either in that the exciter current can have a value above the nominal exciter current or in that the alternator control parameters are fixed in such a way that overheating could occur under unfavorable circumstances. In order to prevent this overheating even under unfavorable circumstances, the temperature is measured preferably in the regulator and the temperature at critical locations is determined from this temperature while taking into account typical parameters. This can be effected in that the temperature or temperatures which would occur in stationary operation are first determined. When an impermissible temperature is detected, the exciter current is reduced by suitable steps until the allowable maximum temperature is not exceeded.

  • Patent number: 5523672
    Abstract: The description concerns a voltage regulator (12) for regulating the output voltage (UB+) of an alternator (10) which is driven by an internal combustion engine. The voltage regulator (12) has an additional circuit (24) which evaluates the exciter current duty cycle (T) and supplies a signal (S1) at its output which is high when the exciter current duty cycle is high and low when the exciter current duty cycle is low. The circuit (24) is integrated in the voltage regulator (12) and the output signal (S1) supplied by it is transmitted via an additional regulator terminal (DA) and can be fed to the control device (25) of the internal combustion engine, where it is used, for instance, to increase the idling speed of the engine and accordingly also to increase the alternator speed and thus the power delivered by the alternator (10). It is also possible to switch off unnecessary consumers with this signal.

  • Patent number: 5374886
    Abstract: In a voltage regulator for an alternator which charges a battery via a charging cable and supplies a vehicle mains with voltage, the output voltage is regulated as a function of the temperature of the battery. The voltage regulator has a power part and a control part, which includes a simulation device for storing data and for determining the temperature of the battery, and hence the optimum charging voltage, by simulation from the stored data. Further, the voltage drop between the alternator and battery can be calculated from the alternator current and the resistance of the charging cable while taking into account correction factors which take into account the different connections of the consuming devices between the alternator and the battery so that the calculated voltage drop and the optimum charging voltage for the battery can be used by the voltage regulator to set the voltage delivered to the battery.

  • Patent number: 5352929
    Abstract: The apparatus for controlling an output voltage of a generator of an internal combustion engine having a starter device, includes a charge control signaling device, an excitation coil for the generator and a voltage regulator controlling an excitation current in the excitation coil and an excitation current limiting device for limiting the excitation current during a predetermined starting phase (.DELTA.t1 ) connected to the voltage regulator. The excitation current limiting device detects whether the engine is in a starting phase. If the engine is in a starting phase, the excitation current limiting device reduces the excitation current so that a voltage is produce at generator terminal D+ which permits no load current and simultaneously guarantees that the charge control signalling device is shut off.
