A garage door opener with solenoid latches is provided with a circuit for energizing the coils of the solenoid latches with power from a 24-volt step-down transformer, either as 120 volt power is applied to a motor to move the door in response to detection of an initial surge of current or as a manual or radio controlled command switch is actuated. In either case, current at a higher level is applied initially to pull in the armature locking pins of the solenoid latches, and thereafter at a lower hold-in level. A transformer with a single turn primary winding or a Hall-effect device may be used to detect the initial surge of current to the motor and in response thereto pull in the locking pins. Thereafter, hold-in current is applied as long as current to the motor is sensed. In the case of sensing actuation of a command switch, a first one-shot triggered by the command switch times the total period (16 seconds) during which the solenoid latches are provided with at least hold-in current, and a second one-shot triggered by the first one-shot at the beginning of its timing period, times a short (100 ms) period during which high, pull-in current is applied. The second one-shot may also be used to inhibit application of power to the motor during the pull-in time. Still other embodiments utilize a mechanical means for sensing when power has been applied to the motor by the door opener.

A control device for an opening/closing member includes a movement instruction outputting unit that outputs a movement instruction of the opening/closing member according to an operation of an operation switch, a driving unit that drives a motor and moves the opening/closing member based on the movement instruction, an entrapment judging unit that judges whether or not entrapment of foreign object by the opening/closing member has occurred when the opening/closing member is being moved by the motor with a sensitivity set at a relevant point as a reference, a drive limiting unit that instructs the driving unit to stop the drive of the motor or drive in reverse rotation of the motor if judged that entrapment of the foreign object by the opening/closing member has occurred by the entrapment judging unit, and a sensitivity changing unit that raises the sensitivity for judging that entrapment of the foreign object by the opening/closing member has occurred by the judging unit when the operation switch is repeatedly operated over greater than or equal to a predetermined number of times within a predetermined time.

A power window apparatus includes a window glass having a horizontal side and an inclined side at the upper end thereof; a window frame for supporting the window glass; and a motor for vertically driving the window glass. In this power window apparatus, a parameter (for example, pulse period) corresponding to a load torque on the motor is measured; a first threshold to determine whether an object is caught between the horizontal side and the window frame, and a second threshold (which is smaller than the first threshold) to determine whether an object is caught between the inclined side and the window frame are set; and the measured parameter is compared with the corresponding set threshold to stop or reverse the motor when the parameter exceeds the threshold.

The invention refers to a quick-opening door comprising: a flexible canvas secured to a motor-driven drum and provided with vertically aligned arrangements of abutment elements that are guided in vertical uprights of the door; an electric duct secured to one of the sides of the canvas and provided with cables connected to a wireless signal transmitter; a plurality of guiding abutment elements distributed along the sides of the canvas with different spaces there between, disposed either singly or in groups; sensors which are disposed in an abutment passage zone and which capture different sequences of pulses during the passage of the abutment elements, thereby determining the position of the canvas at all times; and a contact-detecting band connected to the transmitter via the electric duct and housed in a bag by means of which the canvas is fitted against the ground.

A window position detection and anti-pinch system and method for detecting the presence of an obstruction between a window and window frame of a door assembly of a vehicle is disclosed. The system includes at least one sensing device disposed adjacent the window detecting the position of the window in the window frame and generating an output representative of the detected position of the window. A controller responsive to the output generated by the at least one sensing device compares the window position signal output against predetermined values to determine window position and whether an obstruction exists between the window and window frame.

The invention relates to an adjusting device for a motor vehicle for adjusting a movable element (1) of the adjusting device with a sensor system comprising at least one active sensor part (3) and at least one passive sensor part (12). The object of the invention is to disclose an adjusting device which may be produced particularly easily and inexpensively. This object is achieved according to the invention in that the active sensor part (3) is a fixed capacitive sensor and the passive sensor part (12) forms a component of the movable element (1).

An apparatus for detecting door movement data in an automatic door system is improved in that an opening-direction sensor and a closing-direction sensor are provided on a horizontal member of a slide door frame, while a slide door is provided with a dog having a plurality of actuating portions adapted to switch ON or OFF the opening-direction sensor and the closing-direction sensor as arrayed at an interval in the direction of sliding, so that the opening direction sensor and the closing direction sensor may be switched ON and OFF repeatedly as the door is moved in the opening or closing direction.
