Abstract: A sensor for verifying value documents is designed to determine a luminescence characteristic of a value document that is moved past the sensor for verification purposes, and the provision of a velocity correction of the luminescence characteristic of the value document in the sensor, resulting in a distortion of the measured luminescence intensities. A reference sensor is used to determine an average velocity dependency of the luminescence characteristic of a reference medium, said average velocity dependency being averaged over both opposite directions of movement and being used to determine a velocity dependency of a corrective factor for the luminescence characteristic. Said determined velocity dependency is used to determine the corrective factor for the luminescence characteristic, said corrective factor applying to the velocity of the movement of the value document during the verification process, and the luminescence characteristic is then corrected by said corrective factor.

Abstract: A method for operating a brake system of a vehicle, where the vehicle has an electric machine usable for a regenerative braking of the vehicle and a drive unit usable in an overrun operation for an overrun braking of the vehicle, includes detecting an initiation of deceleration of the vehicle and detecting a driving situation suitable for regeneration. The method further includes initiating the overrun operation of the drive unit and the overrun braking of the vehicle and activating the regenerative braking so as to achieve a setpoint total regeneration torque. The regenerative braking is activated only after a limit value for a difference between an actual overrun regeneration torque by the overrun braking and a setpoint overrun regeneration torque is undershot.
