The invention relates to a windshield wiper drive (1), particularly a motor vehicle rear window wiper drive, comprising a housing (2) having an output dome (3) penetrated by a wiper shaft (5) and penetrating a contact disk (15), said dome having an external thread (19) in the region of the free end (18) thereof, onto which a nut (20) is screwed for tightening the contact disk (15), the nut being disposed inside a protective cap (21) penetrated by the wiper shaft (15). The invention provides that the protective cap (21) comprises an elastomer material. The invention further relates to a motor vehicle.

A method for using a medical navigation system to identify an instrument to be navigated is provided, wherein the instrument includes a reference array having a plurality of markers that form a rigid body, and a location of the markers with respect to each other is not previously known in the navigation system as a characteristic arrangement for a particular instrument. The method includes measuring a distance of each marker relative to the other markers; identifying a spatial arrangement of the markers having the measured distance as an assignable marker array; assigning the assignable marker array to the instrument; and identifying the instrument based on the assigned marker array.

The invention relates to a device for variable control of the gas exchange valves of an internal combustion engine, of which at least one gas exchange valve is triggered by a cam of a camshaft, which cam has a cam contour with a circular portion of the cam bottom and a cam apex portion. For variably adjusting the cam contour, a pressure-fluid-actuated piston guided by the cam and retractable and extensible radially continuously, is provided which on its end forms at least a part of the cam apex portion.

Proposed is a dosing module for injecting liquid urea-water solution into the exhaust tract of an internal combustion engine, which dosing module is composed of two pumps, specifically a delivery pump (5) and an aeration pump (15). This permits firstly the injection of urea-water solutions and secondly safe and reliable ventilation of the system when the internal combustion engine is to be shut down.

A fitting for a vehicle seat, such as a motor vehicle seat, includes a first fitting part, on which a ring gear is formed, and a second fitting part, on which a spur gear is formed, which meshes with the ring gear. The two fitting parts are in transmission connection with each other. A rotatably supported eccentric rotates in the circumferential direction for driving a relative rolling motion of the spur gear and the ring gear. The outside of the eccentric is arranged in a plain bearing bushing in the radial direction. The plain bearing bushing is arranged in a bearing seat, such as a collar of the first or second fitting part. The plain bearing bushing has a wall thickness of less than 1 mm and is connected to the bearing seat in a bonded manner by laser welding. A running side of the plain bearing bushing is plastic-coated.

The invention relates to a treatment apparatus (1) for treating a surface (21) of a body (2) with a first treatment medium (31) and a second treatment medium (32). In this respect, the treatment apparatus (1) includes a holding device (5) rotatable about an axis of rotation (4) for receiving and holding the body (2) and a rotary drive (6) rotationally fixedly coupled to the rotatable holding device (5) as well as a supply device (7) for supplying the first treatment medium (31) and the second treatment medium (32) to the surface (21) of the body (2) held in the holding device (5). The treatment apparatus includes a collection container (8) having a separation element (80) which separation element (80) divides the collection container (8) into a first chamber (81) and into a second chamber (82) such that the first treatment medium (31) can be collected in the first chamber (81) and the second treatment medium (32) can be collected separately in the second chamber (82). In accordance with the invention, the collection container (8) includes a base chamber part (800) not movable with respect to the holding device (5) and the separation element (80) is movably arranged between a first position (A) and a second position (B) such that the first treatment medium (31) can be led off into the first chamber (81) in the first position (A) and the second treatment medium (32) can be led off into the second chamber (82) in the second position (B).
