摘要:
The present invention relates to a method for monitoring the alertness of the driver (4) of a vehicle, comprising: - continuously detecting and evaluation of at least one physical parameter (PP) of the driver (4) while the vehicle is in motion, - transmitting a periodic audio signal (S) with a predetermined frequency into a vehicle interior (1) within a predetermined time period if the evaluated physical parameter (PP) is in a critical range, whereby the critical range indicates an appropriate level of fatigue of the driver (4). Furthermore the present invention relates to an apparatus for monitoring the alertness of the driver (4) of a vehicle, comprising: - a monitoring unit (2) with a sensor unit (2.1), which detects at least one physical parameter (PP) of the driver (4), and - an evaluation unit (2.2), which evaluates the detected physical parameter (PP) while the vehicle is in motion, and whereby - the evaluation unit (2.2) is coupled to an audio device (3), which transmits a periodic audio signal (S) into a vehicle interior (1) within a predetermined time if the evaluated physical parameter (PP) is in a critical range.

The invention relates to an indication device, especially for a motor vehicle. Said device comprises an index which is arranged to swivel about an axis of rotation and which points away from the axis of rotation into a direction. A counterweight is arranged and can be swiveled about the axis of rotation together with the index, the counterweight pointing away from the axis of rotation in a direction counter to the direction of the index. The material of the counterweight and the material of the index have substantially the same density.
