A method for conditioning a coded signal including: determining a time constant, on the basis of which the data were coded, from the received signal and evaluating the received signal according to the determined time constant. A device for conditioning a received signal that transmits coded data has a determining device for determining a time constant, according to which the data were coded, from the received signal and an evaluation device for evaluating and processing the received signal according to the determined time constant.

Method and device for preprocessing a received, data coded transmitting signal

To transmit data which is supplied by a rotational speed sensor in the form of an alternating signal as well as additional data via a signal line, a sequence of current pulses of a predetermined duration is derived from the alternating signal, the pulse intervals or interpulse periods containing the information on rotational speed. The additional data is transmitted in the interpulse periods, and transmission of the additional data is synchronized by the individual rotating signal sensor pulses. Preferably, the method is employed for active sensors, and both the sensor pulses and the additional data are transmitted in the form of current signals. During standstill, in the absence of a sensor pulse, transmission of the additional data is triggered by auxiliary synchronization pulses.

Method and circuit for transmitting information on rotational speed and additional data

The present invention relates to a method of transmitting data in pulse intervals of a rotational speed signal, wherein the maximum number of the transmittable data is determined from the period of time which is required for transmitting an information and from a time, which corresponds to the length of the pulse interval, and the maximum number of the data transmittable in a pulse interval is adapted by setting as time, which corresponds to the length of the pulse interval, a value that results from at least one recently measured pulse interval in consideration of a maximum value of the wheel acceleration. The present invention also relates to a circuit arrangement for implementing the method.

Method of transmitting data within pulse intervals of a rotational speed signal, and circuit arrangement for implementing the method

A circuit configuration for actuating active- and/or passive-operated warning signal generators or warning lamps (WL,, WL,) comprises an integrated circuit (IC,) having individual actuating steps (,) and connections for the individual warning signal generators. Moreover, an adapter connection (WLCON) is provided which upon connection to chassis configures the circuit (IC,) 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&mdash;if left open&mdash;the circuit (IC,) for actuating two active warning signal generators (Wla).
