Abstract: A vehicle seat provided with an active suspension, comprising: a resiliently mounted vibration-isolating frame (2), a seat mechanism (6a, 6b, 8a, 8b, 10, 13), which can be adjusted by means of at least two actuators (4a, 4b) and is articulated on the vibration-isolating frame (2), at least two acceleration sensors (11, 12), of which the first acceleration sensor is arranged at a spring supporting point in the vicinity of a first joint axis, and the second acceleration sensor is arranged at a spring supporting point in the vicinity of a second joint axis, and at least two final control elements (S1, S2) and power and control electronics (R1, R2, FFC, E, CU) with which the signals of the acceleration sensors are processed and converted into desired adjusting forces (F*1, F*2), which serve as control commands for the final control elements (S1, S2) for operating the actuators (4a,4b), so that the vibration-isolating frame (2) can be adjusted by means of the two actuators (4a, 4b) in two degrees of freedom

Abstract: Process for monitoring the residual charge and the capacity of a battery, where at least two voltage-current measurements have been carried out on the load-carrying battery. The current load of the battery selected here should be greater than 30% of the nominal capacity per hour, e.g. for a 100 Ah battery, at least 30 amperes. The initial voltage-current measurement is taken at an initial time for an initial load condition of the battery. A second voltage-current measurement is carried out at a second time for a second load condition of the battery. It is essential here that the load condition of the battery has changed because of the current that has been drawn. The current-voltage measurements produce an initial measuring point and a second measuring point. The two measuring points set an interpolation line and determine the point of intersection with a limiting voltage level (UGr). This point of intersection is marked by a so-called limiting current (IGr).

Abstract: The apparatus is an electromagnetically actuated lock which has a movable part, which is prevented from rotation or displacement by a barring bolt that extends into a recess of the movable part. Locking pins extend into the barring bolt and which locking pins positively lock the bolt in the withdrawn or retracted position when access is authorized and which locking pins also positively lock the bolt in the extended position when access is unauthorized.

Abstract: A brake actuator for electrically actuated vehicle brakes includes a spindle assembly without additional gear stages. The forces required for engaging the brake are realized herein by utilizing the spindle assembly. The brake actuator includes a brake pad which is pressed against a brake disc with the aid of an electric motor (4) operating as an electric drive. A planetary-roller spindle assembly operatively connects the electric motor to a brake piston on which the brake pad is mounted. The electric motor (4) is connected via the spindle assembly to the brake piston (32). The spindle assembly (16) is arranged in the displacement direction of the brake pad and the brake piston (32) is journalled so as to be axially displaceable with the brake pad. The spindle assembly (16) includes a spindle rod (18) which is mounted so as to be an extension of the rotor (8) of the electric motor (4).

Abstract: An electrical windshield wiper drive for a vehicle, includes a windshield wiper arm and an electric motor drive in the form of an ultrasonic motor having a drive shaft connected to the windshield wiper arm for rotatably driving the wiper arm.
