Abstract: An electric motor, in particular for an electromechanical brake device of a vehicle, includes a stator and a multi-pole rotor with an odd number of rotor poles. Recesses are defined in the central region of the rotor poles, drive assembly, and electromechanical brake device for a vehicle.

Abstract: A method for characterizing an electromechanical actuator unit for a vehicle brake, the electromechanical actuator unit comprising an electric motor and an actuator coupled to the electric motor. The actuator can be moved over a first area of movement without generation of a brake force and over a second area of movement with modification of a brake force. The method is carried out when the actuator moves within the first area of movement, and comprises the following steps: a) a voltage applied to the electric motor is interrupted, b) at least one parameter is determined while the electric motor runs in the generator mode, and c) at least one value is determined for a motor constant of the electric motor on the basis of the at least one parameter. The invention also relates to a vehicle brake, as well as to a computer program and a control unit for implementing the method.

Abstract: A motor vehicle brake, in particular a combined hydraulically and electromechanically actuatable motor vehicle brake, with an actuator assembly comprising: a housing, an actuator which can be moved relative to the housing for hydraulically or electromechanically moving a brake lining, a motor drive, a movement mechanism which is arranged between the motor drive and the movable actuator, a gear arrangement which is paired with the movement mechanism, and a separate self-locking device which is designed to block the movement mechanism when necessary, wherein the movement mechanism has a ball screw drive with a rotatable spindle and a nut which can be moved in the housing in a linear manner. The nut can be moved within the housing in order to move the actuator by rotating the spindle, and the gear arrangement has at least two gear stages.

Abstract: In embodiments of battery charging interrupt, a device (102) includes a capacitive touch interface (104), a battery (110), and a charging circuit (108) that charges the battery when the device is coupled to a power supply (114). A touch detection system (106) detects a conductive contact on the capacitive touch interface of the device, and the touch detection system determines a level of noise on the capacitive touch interface. The level of noise may increase due to the conductive contact on the touch interface while charging the battery. A device controller (126) determines a charge level of the battery. The device controller can then interrupt charging the battery when the level of the noise exceeds a noise level threshold (128) and when the charge level of the battery exceeds a minimum charge level.

Abstract: A method and an apparatus are provided for use in a user device for limiting the ability of the terminal of the user device to replay protected content. The low-level key that is used by the decryption component of the terminal to decrypt content is transient in that it expires if at least one predetermined expiration criteria is met. After they key has expired, it is no longer valid and thus cannot be used by the decryption component to decrypt protected content. Limiting the ability of the terminal to replay protected content is preferably accomplished in a way that does not affect the ability of the terminal to play and replay unprotected content.
