A method for controlling the operating mode of a drive of a vehicle that includes a main drive unit and an auxiliary tractive energy source. The method includes operating the main drive unit, detecting the duration of actuation of an uninterrupted actuation of a brake pedal, and detecting whether the duration of actuation is above a minimum duration by comparing the duration of actuation with a minimum duration. The main drive unit is switched off if it has been detected that the duration of actuation is above the minimum duration. Otherwise, operation of the main drive unit is continued if it has been detected that the duration of actuation is not above the minimum duration. A device for carrying out the method is also described, which includes a timer for detecting the duration of actuation and a comparator for comparing the duration of actuation with a minimum duration.

In at least one embodiment of the present invention a seat-belt retractor is provided. The seat-belt retractor comprises a locking system that is controlled by means of at least one vehicle-sensitive sensor. The sensor has an alignment mass for autonomous alignment and is configured to pivot on the seat-belt retractor when the angular installation position of the seat-belt retractor is changed and when the seat-belt is extended, the sensor can be fixed in position by a blocking device. The blocking device is friction-controlled by the rotation of the belt shaft in the extension direction. The blocking device includes a rotatably mounted blocking lever which can be displaced into a release position for the sensor by a control lever that is coupled to the belt shaft by a friction coupling when the belt shaft rotates in a retraction direction.

The invention relates to a filter installation, especially a seawater filter installation, comprising at least one fluid line (18,20) for transporting a biological fluid, a filter device (54) which is mounted in said fluid line and comprises at least one filter element (22) in a filter housing (10), and means for biological decontamination. The fact that the means for biological decontamination contain active substances that can be introduced into the filter housing (10), such as inert gases or special metals, ensures that toxic impurities cannot enter and the active substances used are ecofriendly unlike chemically produced fungicides and herbicides. The invention also relates to a method for operating said filter installation.
摘要:
Process for preparing hydrocyanic acid by catalytic dehydration of gaseous formamide, in which a formamide-containing recycle stream is obtained from the product mixture after the dehydration and is recirculated to the dehydration, wherein the formamide-containing recycle stream contains from 5 to 50% by weight of water.

A latch (1) for a top of a vehicle comprises a latching hook (3) which is disposed in a guide plate (10), preferably having a U-shaped cross-section, to be movable from a closed position into an open position on a defined path (41) via guiding means (bolt 8, pin 9). A geared motor (4) is provided for pivoting a actuation lever (15) which is connected to the latching hook (3). The connection between the latching hook (3) and the actuation lever (15) is realized through several levers (11, 12, 13) which are connected to each other in an hinged fashion. The motor-driven latch for a top with compact space-saving structure, has a latching hook with a larger radius of motion to increase the separation from the windscreen frame in the open position.

An amorphous soft magnetic thin film material for forming shielding and keeper applications in MRAM devices. The amorphous soft magnetic material may be deposited using Physical Vapor Deposition (PVD) in the presence of a magnetic field, in order to form shielding layers and keepers in a multi-layer metallization process. The soft magnetic material may be an amorphous metallic alloy, such as CoZrX, where X may be Ta, Nb, Pd and/or Rh.

The invention relates to a method for detecting rpm signal errors, in which pulses (t0, t2, t4, t6, t8 and t10) and pulse intervals (t1, t3, t5, t7, t9) are generated by poles that generate rpm signals and are disposed on the circumference of a pole wheel. To ascertain a change in speed, pulse intervals (t1, t3, t7, t9) within a first allowable tolerance range are compared in a first step for equality and in a second step for inequality in terms of duration, during one wheel revolution.
摘要:
The invention is based on a system for changing a signal representing rotational motion in a motor vehicle with first means for generating a first signal representing the rotational motion and a second means for generating at least one second signal representing additional information (direction of rotation, air gap, and/or brake lining wear). In addition, a third means is provided, by means of which the first signal (rotational speed signal) can be changed as a function of the second signal (direction of rotation, air gap, and/or brake lining wear). The essence of the invention is that the first means is designed in such a way that the first signal (rotational speed signal) assumes at least two first current values and/or two first voltage values. In addition, the third means is designed in accordance with the invention in such a way that, to change the first signal (rotational speed signal), at least one of the first current values and/or voltage values can be changed at least for a certain period of time into at least one second current value and/or voltage value as a function of the second signal (direction or rotation, air gap and/or brake lining wear).
