Abstract:
A safety for a displacement device mounted on a motor vehicle. A door control device (TSG) and a central control device (ZSG) of a motor vehicle including a power switch (LS) which gets an electromechanical unit (Sch) under a blocked (safe) state. The central control device is connected to the door control device and other door control devices of the vehicle by means of links (CAN) such that at least one electromechanical unit is controllable by the central device with the aid of the link. The door control device is connected to the central control device by a hardwired electric link (St) which is independent from the links. The potential of a control connection of the power switch or the power connection of the door control device can be controlled by the central control device by means of the independent hardwire electric link.
Abstract:
A controlling device with a sensor for the detection of a position of a window pane of the window lifter depending on a driving motion of an actuation is provided. The position signals generated by the sensor, for example by a path sensor or rotary pulse sensor, concern thereby the position of the window pane. Position signals are for example gained from a waviness of a driving power of a mechanically commuted electromotor. The sensor signals can thereby be evaluated by the controlling device. The controlling device includes an analogue or a digital computer unit which provides a function for the combined evaluation of the current position of the window pane and a condition of a roof of the motor vehicle. The evaluation can thereby occur for example by a respective logical circuit as computer unit, by a hard-wired program logic as computer unit or by a programmable computer unit.
Abstract:
The invention relates to a method for contactless approach of a lower stop position of a motor vehicle window pane operated by extraneous force using a sensor device which during lowering of the window pane generates path-dependent signals and forwards them to an electronic evaluation unit in which the sensor signals are counted. During two separate phases (A) and (B) system deficiencies of a window raising mechanism are compensated and the pane is lowered. On reaching a certain counting state which lies in front of the position of the fixed contactless stop, a drive is switched off. The first phase (A) and the second phase (B) of the adjustment movement of the drive are separated by a boundary value (2) which reflects a system state of window winding raising mechanism so that the sensor signals of the first phase (A) can be associated with compensating cable slack and the sensor signals of the second phase (B) can be associated with the actual movement of the window. For determining the slowing-down path of the window pane which is to be expected the operating voltage of the drive is used in addition to the lowering speed of the window.
Abstract:
A polarized relay with an electromagnet which consists of an exciter coil and a coil core mounted in the exciter coil. On each of two end sides of the electromagnet is a permanent magnet displaceable along its magnetic axis. The same pole, for example, the north pole (N), of each of the two permanent magnets face the end sides of the electromagnet. The relay is capable of tri-stable behavior, that is, it can switch between three states, with only one exciter coil. Preferably, the tri-stable function of the relay controls a commutator motor between "rest," "clockwise running," and "counter-clockwise running" states.
Abstract:
The invention relates to a process and apparatus for detecting the speed and rotary direction of a rotary drive by using a signal-transmitting or signal-changing element which is connected rotationally secured to the rotary drive. According to the invention, during rotation of the signal-transmitting or signal-changing element a rotary direction coded signal is produced which is detected by a sensor and which is supplied to an electronic evaluator unit. The aim of the invention is to provide a process and device for detecting the speed and rotary direction of a rotary drive which manages with one sensor unit for a high analysis of the speed and rotary direction.
Abstract:
A method for sorbing a gas using an ionic liquid to sorb a vapor having an electric multi-pole moment. The ionic liquid comprises an anion and a cation. The electric multi-pole moment may be an electric dipole moment and/or an electric quadru-pole moment. The sorption may be an adsorption or an absorption. The ionic liquid may be a liquid that substantially contains only anions and cations, while not containing other components, such as water. Alternatively, a solution containing the ionic liquid and a solvent or further compound, such as water, may be used.

The invention relates to a method which uses magnetic ionic liquids for the liquid-liquid, liquid-solid, or liquid-gas extraction, wherein the partition of the phases occurs in a magnetic field.
Abstract:
A method of impeding water input in an ionic liquid is provided, wherein the method comprises adding an additive to the ionic liquid wherein the additive comprises an orthoester. In particular, at least some residues of the additive may remain or may be present in the ionic liquid during the usage of the ionic liquid. For example, the additive may be formed by the orthoester or by a mixture of orthoesters.
Abstract:
An especially failsafe method for operating an electric window lift for closing and opening a window of a convertible is provided. A threshold value that is relevant to the triggering of an anti-pinch protection system of the window lift is regularly adapted to the actuation-position-dependent behavior of a sensed operating quantity of the window lift, at least in a lower region of the actuation path of the window, both when the top of the convertible is closed and when it is open. At least for the first window closing process after a closing of the top, the threshold value is rigidly predefined in an upper region of the actuation path of the window.

The invention relates to a method for controlling an actuator (1), particularly of a vehicle, wherein the actuator (1) is displaced in a predetermined position (4) by means of a drive (5). The force variable acting on the actuator (1) in the position (4) is determined, compared to a target value, and in case the target value is exceeded, the drive (5) is actuated for system relief. The invention further relates to an displacement system (8) for an actuator (1), particularly of a vehicle, comprising a drive (5) for displacing the actuator (1) and a control module (6), designed for the control of the drive (5) according to the method.
