Abstract: A warning light is provided for optically displaying at least one and preferably a number of different operating states, of a technical device such as a machine, an installation, a vehicle or the like. The warning light has at least one luminous element for emitting a sequence of illumination pulses within a specific time interval for the display of a specific operating state, in which the illumination characteristic of the illumination pulses are determined by at least one illumination parameter (P) such as brightness, illumination duration, frequency, color, direction of emission or the like to substantially improve perception of the optical display especially for a particularly critical operating state. This is achieved according to the invention by providing an aperiodic change in at least one of the illumination parameters (P) in a specific time interval.

Abstract: A proposal is made for a warning light for optically displaying at least one operating state, in particular a number of different operating states, of a technical device such as a machine, an installation, a vehicle or the like, having at least one luminous element for emitting a sequence of a number of illumination pulses within a specific time interval during the display of the specific operating state, the illumination characteristic of the illumination pulses being determined by at least one illumination parameter (P) such as brightness, illumination duration, frequency, color, direction of emission or the like, the perception of the optical display of the specific operating state, especially of a particularly critical operating state, is substantially improved. This is achieved according to the invention by virtue of the fact that an aperiodic change in at least one of the illumination parameters (P) is provided in the time interval.

Abstract: The invention concerns an arrangement for carrying out steering angle or steering wheel angle measurements (&agr;) in motor vehicles. The arrangement uses a resolver for transmission purposes. Advantageous developments concern the use of the resolver for the additional transmission of switching information in both directions and for transmission of energy using frequency-separated or time-multiplexed transmission channels.

Abstract: The invention concerns an arrangement for carrying out steering angle or steering wheel angle measurements (&agr;) in motor vehicles. The arrangement uses a resolver for transmission purposes. Advantageous developments concern the use of the resolver for the additional transmission of switching information in both directions and for simultaneous transmission of energy using frequency-or time-division selected transmission channels.

Abstract: This invention relates to a steering angle sensor, particularly for yawing moment control in automotive vehicles. In order to determine the required steering angle of the steered wheels the angle of rotation of the steering wheel is measured. To this end, a code disk is used which enables the reading of the position of the angle of rotation of the disk. As the steering wheel can perform a plurality of revolutions in order to pivot the steered wheels the result readable at the code disk is ambiguous. This invention suggests a counter which records the revolutions of the code disk, starting from a zero position. Further advantageous developments involve the design of the gear mechanism and the evaluation of the signals of the counter.
