摘要:
A spindle drive for a movable component includes a threaded spindle, which can be driven in rotation about a rotational axis by a reversible drive. A spindle nut is mounted nonrotatably on the spindle. By means of the spindle nut, a transmission element connected to the movable component can be driven axially with respect to the spindle axis. The spindle nut can be connected to and disconnected from the transmission element by a connecting device. A nut position sensor detects the position of the spindle nut and a component sensor detects the axial position of the transmission element. If it is concluded that there is plausibility between the signals of the nut position sensor and the component sensor, the spindle nut can be connected to the transmission element by the connecting device.

A rain sensor arrangement for an operator for a window having a frame, a sash pivotable with respect to the frame, and a pane mounted in the sash, wherein the operator is adapted for pivoting the sash between a closed and an open position and vice versa, and is controlled via control circuitry responsive to input signals from at least a rain sensor. The rain sensor has at least one sensing area arranged so as to be protected against rain by the window, when the sash is in the closed position.

A sensor measuring by capacitance, in particular for the detection of an obstruction of objects or body parts by motor driven devices, comprising an arrangement of a multitude of electrodes on a support and means to measure a capacitance or a capacitance change, is disclosed. The sensor is of a flat and film-like embodiment with a support made out of a film material for the arrangement of the electrodes. Furthermore, a capacitive sensor system, for detection of an obstruction situation of objects or body parts with motor driven devices using several sensors of the above design, is disclosed, whereby an obstruction situation is detected, if a selection of several sensors is responding.

Auxiliary sensors 51 and 52 are disposed on exterior and interior side surfaces 31 and 32 of a transom 3. The sensors 51 and 52 have detection areas A1, A2, B1 and B2 which extend through the doorway 2 and which cross each other in a space vertically above a track 10. While detection signals are produced by both auxiliary sensors 51 and 52, the door is kept open. If detection signals are produced from only one of the auxiliary sensors 51 and 52 uninterruptedly for a predetermined time, the door closing action is allowed to start.
摘要:
A test device for testing automatic door systems has a test circuit including a display, a micro-controller, a memory for storing data and a test program, and a control switch for controlling operation of the test program by the micro-controller. The test device is installed by interposing the test circuit between the controller and sensors of the automatic door system. A selector switch on the test device is moveable between first and second positions. When the selector switch is in the first position, it completes a data path between the test circuit and the controller and blocks the exchange of data between the sensors and the test circuit and the first connector. When the selector switch is in the second position, it completes a data path between the test circuit and the second connector and blocks the exchange of data between the controller and the test circuit and the second connector. Pushing the control switch steps the micro-controller through the test program to individually test the controller and each of the sensors.
