摘要:
A multi doorlock includes a doorlock unit (200) installed to a hinged door (100), a non-powered DC motor (300) installed to the doorlock unit, and links (400) (410) having one ends connected to the DC motor and the other ends installed to a doorframe, the links being folded or unfolded with each other when the hinged door is closed or opened. The doorlock unit (200) frequently changes a braking resistance of the DC motor (300) while the hinged door (100) is opened or closed, thereby controlling an opening/closing speed of the hinged door. A relay switch (700) is connected to both ends of a power line (330) of the DC motor (300) to short the DC motor on occasions. When it is intended to fix the hinged door (100), the relay switch (700) is operated to short the DC motor (300) such that the hinged door is not moved.

A system for controlling the operation of a garage door is provided. The system controls the closing of the garage door. The system includes a garage door including a motor and a control arm trolley moving along a track. The motor and the control arm trolley control movement of the garage door. The system further includes a switch, which indicates the open or closed status of the garage door. In one embodiment the switch is a magnetic switch connected to the track for performing a mechanical check. Finally, the system includes a control unit including a timer connected in parallel with a push button, IR or RF control. The timer stores a pre-defined schedule for controlling garage door operation. The control unit controls garage door operation based on the mechanical check and the pre-defined schedule.

Low cost, low power consumption radio frequency transceivers are incorporated in barrier operator control systems for transmitting signals between an operator control unit, one or more remote control units, a diagnostic or calibration device and an obstruction detector. Similar detector devices, including such transceivers, may be employed in loading docks for detecting the status of dock levelers and vehicle restraint devices. Radio frequency communication eliminates the need for hard wiring and also provides for transmission of commands and status information between various control units.

A door operator for use with a door includes an arm that extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

A gate assembly comprising a gate mount and a gate mounted for movement on the gate mount between an opened position and a closed position. The gate assembly further comprises an illumination system mounted on the gate mount for turning on a light mounted on the gate mount when someone approaches the gate when it is dark in the vicinity of the gate.

A system for operating an automotive liftgate includes a motor drive adapted for positioning the liftgate, and at least one telescopic strut positioned between the liftgate and an adjacent body structure. A controller operates the motor drive so as to place the liftgate in a predetermined position, such as a fully closed or fully opened position, in the event that a sensor detects unintended movement of the liftgate.

The invention regards monitoring the functional position of a hinge through a non contacting sensor, in particular working with a magnetic field, comprising a rotation position generator and a sensor unit, measuring over an angular range, wherein the rotation position generator, in particular the magnet on the one hand, and the sensor unit with the sensor element on the other hand, are opposing each other at a distance, and are rotationally fixed on the one hand to one of the pivoting parts of the hinge, and on the other hand to one of the non moving parts of the hinge, or of the component carrying the hinge.
摘要:
A method and system for controlling vehicle door position in improved reliability of a vehicle door electromechanical positioning components. The vehicle door control system includes an abnormality detector for detecting abnormal operation of the vehicle door by a deviation of expected door position and/or velocity. If abnormal operation is detected, operation of the electrical motor driving the door is ceased for a predetermined time period. Operation is then resumed if the abnormal condition has been removed. The control system may include a counter for counting a number of attempts to resume operation and further attempts to resume may be ceased if the counter exceeds a predetermined count value. The motor or door positioning system may include a locking device that locks the vehicle door at various positions and the control system use indications of a locked position indicator to determine whether or not to resume operation of the electric motor.

A door apparatus includes a door having a hole and configured to be slidable with respect to a vehicle body, a member configured to open and close the hole, a first detector configured to detect a position of the member relative to the hole to determine an openness of the hole, a second detector configured to detect a position of the door relative to the body, and a unit configured to be activated to project from one to another of the body and the door, so as to abut on the another such that the door is stopped from sliding in an opening direction, when the openness is greater than a threshold, and the position is between a full-closed position and a midway position.
