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.

Motor vehicle roof with a roof opening, a movable closing element to selectively close or at least partially clear the roof opening, a wind deflector in a front edge area of the roof opening and which is movable between lowered and fully raised positions, and a positioning device for setting intermediate positions of the wind deflector which has a holder which engages the wind deflector and a driven displacement mechanism for vertically displacing the wind deflector into the intermediate positions. The adjustment mechanism has a guide element which is driven by the drive into motion along the wind deflector with an inclined guideway along which an engagement element which is connected to the holder is movably guided. The engagement element is supported on a body-mounted carrier such that it can be moved with respect to the carrier only normal to the direction of motion of the guide element.

Method and apparatus for facilitating accessing home surveillance device data, preferably an IP camera video stream, by a remote user device at the remote user device's instigation, over the Internet through a home router, the facilitating including incorporating a smart gateway in local communication with the home router and in persistent or intermittent communication with a remote Internet server to facilitate communication of data over the Internet at the remote user device's request through direct communication between the remote user device and the smart gateway, the smart gateway in local communication with the home surveillance device such as an IP camera, the direct communication facilitated by a “hole punch” type of technique.

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.

A magnetically inductive flow meter including a first electrode arrangement for galvanically contact detection of an induced voltage dependent on the flow velocity of the medium as a first measurement signal, and a second electrode arrangement for capacitive detection of an induced voltage as a second measurement signal, wherein by determining and evaluating characteristic parameters of the first and second measurement signals, diagnostic messages on the status of the medium and / or the flow meter are obtained, such as the content of gas bubbles in the fluid, electrode corrosion, electrical conductivity of the medium, damage to the electrically insulating interior lining of the measuring tube, deposits on electrodes, magnetic interference fields, electrode short-circuits and / or the fill level of the measuring tube.

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).
