摘要： The method allows communication with a built-in sensor, in particular a rotational speed sensor, which supplies successive signal pulses as output signal. The sensor is preferably built into a motor vehicle in such a way that it can be supplied with a supply voltage externally via a voltage supply line. The sensor is placed into a detection mode. The supply voltage on the voltage supply line is externally modulated. The modulated supply voltage received in the sensor is analyzed with regard to the fulfillment of a predetermined criterion stored in the rotational speed sensor. And, finally, the received modulated supply voltage is interpreted as an external communication signal if the criterion is fulfilled.

摘要： A method of identifying a direction of rotation of a wheel using Hall probes which are disposed about the circumference of the wheel. In this case, a first, a second and a third Hall probe are disposed successively, so that the second Hall probe lies between the first and third Hall probes. From the output signals of the three Hall probes, two evaluation signals are obtained, through comparison of which the direction of rotation of the wheel is determined.

摘要： A comb filter has series connected integrators to which is fed a digital data stream at a high sampling rate in order to yield a digital data stream at a low sampling rate. The most significant bits of the digital data stream are reset in the first and second integrators, the resetting of the bits in the first integrator being stored in a counter. The counter reading of the counter is fed into the most significant bits of the last integrator at a reset time.

摘要： A digital/analog converter with a weighted capacitive converter network is provided with weighted stray capacitors for reducing non-linearities in switching. Additional stray capacitors are connected in parallel to the otherwise present stray capacitors for that purpose. In the higher-value network capacitances, the additional stray capacitors are positive, in the lower-value network capacitances, the stray capacitors are effective, i.e. their effect is negative. The converter is constructed differentially in its entirety. The combination allows the optimization with regard to the chip surface.

摘要： An apparatus for stepless control of electric loads by the phase angle principle includes a semiconductor switch element. A trigger circuit is connected to the semiconductor switch element for furnishing turn-on pulses for triggering the semiconductor switch element. The trigger circuit includes at least one current flow detector, a turn-on pulse pregenerator circuit, a switch and driver unit, and a time-dependent circuit element. The on-state angle of each current half-wave is compared with a maximum allowable limit value of the on-state angle through the use of the current flow detector and the time-dependent circuit element, and a further triggering of the semiconductor switch element is prevented if the maximum allowable limit value of the on-state angle is exceeded. An apparatus for controlling the brightness of an incandescent bulb includes a transformer having a primary winding with two terminals and a secondary winding connected to an incandescent bulb. An alternating voltage source has one pole connected to one terminal of the primary winding. The semiconductor switch element has one main electrode connected to the other terminal of the primary winding and another main electrode connected to the other pole of the alternating voltage source.

摘要： Implementations to mitigating side effects of impedance transformation circuits are described. In particular, mitigation circuitry may be coupled to a high impedance circuit to minimize or eliminate non-linear output of the high impedance circuit in order to provide a well-defined bias voltage to the input of a buffer or amplifier device coupled to a capacitive sensor. Additionally, the mitigation circuitry may be coupled to the high impedance circuit to reduce or eliminate rectifying effects of the high impedance circuit. Accordingly, a bias voltage can be utilized to provide a stable operating point of the buffer or amplifier device via a high impedance circuit utilizing one or more impedance transformations.
