摘要:
A method and apparatus for controlling the flow of data units across a bus bridge and an inter-bus communication system employing same is disclosed. In accordance with the method, the apparatus detects operational states of the bridge and disables load access to the bridge when a first predefined operational state exists and enables load access when a second predefined operational state exists.

The invention relates to a windshield wiper having arm (10), which is driven via a drive shaft and on which a wiper blade is (20) is pivotably connected. At least one spray nozzle (64) for providing fluid to the windshield is disposed on one of the pivotable parts (10,22) and is connected via a water inlet (56) to a water pump. A nozzle body (40) with one inlet conduit (42) and at least one outlet conduit (44) is provided in a housing (36). A spray nozzle is mounted in the nozzle body. Both inlet and outlet conduits have openings on a jacket face of the nozzle body. A diaphragm (58,70), in a pressureless state, closes the inlet conduit (42) and the outlet conduit (44) on the jacket face.
摘要:
The invention relates to a device and a method for actuating a wiper system. The device comprises a drive unit (2) for driving at least one wiper arm (4), and a control unit (6), wherein the control unit (6) is designed to set a wiping frequency of the wiper arm (4) as a function of a load variable which is dependent on the torque which is to be applied by the drive unit (2) during a wiping operation.

A windshield wiper has a wiper arm (10), which is driven via a drive shaft and is made up of a fastening element (12) and a hinge element (14), pivotably connected to it via a swivel joint (18). The hinge element has a wiper rod (36) to which a wiper blade (42) is pivotably connected, and at least one spray nozzle (42) is disposed on a pivotable part (10, 22), the spray nozzle communicating with a water pump via a water line (48). An electric resistance heating line (50, 60) in wire form is guided through the water line (48) and has two insulated current-carrying leads (64, 66), which on one end are electrically connected to one another and on that end, with the spray nozzle (42, 54) of a heating-conducting material, form a contact point (62, 68) with good heat transfer.
摘要:
The invention relates to a control device (160) for a drive unit (120) of a vehicle windshield wiper system (100) comprising at least one wiper arm (140). The control device (160) is designed to determine a load quantity (L) of the drive unit (120) and to set the wiping frequency (WH) of the wiper arm (140) on the basis of the ratio of the load quantity (L) to at least one load threshold value (LS). Furthermore, the control device (160) is designed to set the wiping frequency (WH) depending on the current speed (v) of the vehicle.

The invention relates to a wiper system with a wiper drive (1), which is comprised of a wiper motor (2) and a gear (3). A wiper arm shaft (14) for a wiper arm (19) can be driven via the output shaft (5) of the gear (3). Linking points (31, 32, 33) for accommodating the wiper drive (1) on a surface (24, 40) are arranged in the housing area (7) of the wiper drive (1). The linking points (31, 32, 33) of the wiper drive (1) each feature a decoupling element (41, 42, 43), in which fastening elements (55) to mount the wiper drive (1) either on a vehicle body (24) or on a screw-down surface (40) are accommodated.
