An apparatus for automatic movement of sliding windows in a motor vehicle, comprising a d.c. electric motor that moves a window (F) so that it slides along guides, including an electronic control module for controlling the d.c. electric motor, in particular a microprocessor. The electronic control module measures a current (I) of the motor and a position (X) of the window (F), and drives reversal of operation of the electric motor if it is verified that the current (I) is higher than a threshold current (I.sub.th) and the position (X) of the window (F) falls within a given zone (APZ) of a path (P) of movement of the window (F). The anti-pinch circuit device measures a back electromotive force (E; E.sub.m) of the motor, and the electronic control module calculates the position of the window (F) as a function of the back electromotive force (E; E.sub.m) of the motor.

A car window circuit is provided. The car window circuit provides a closed-circuit voltage step up converter that increases the car window movement speed of slow or old window power circuits. The car window circuit contains a DC converter module, a case, an electrical input, an electrical output, and a circuit check module. The DC converter module resides within the case, serving as the voltage step up converter. The electrical input, the electrical output, and a ground wiring are electrically connected to the DC converter module. The circuit check module is electrically connected between the electrical input and the DC converter module, serving as the car window circuit voltage regulator. When installed to a window power circuit, the car window circuit will indicate successful installation through the activation and illumination of a power indicator LED and a bridge indicator LED.

A door control system is provided. The control system includes a controller configured to control a door via a motor. The motor is powered by a battery and bypasses the controller via relays and/or switches when power to the controller is disconnected.

A vehicle includes a body, an access aperture that is defined by the body, a closure panel, a load ramp, and a moisture sensor. The access aperture provides access to an interior of the vehicle. The closure panel selectively covers at least a portion of the access aperture. The closure panel is movable between an open position and a dosed position relative to the access aperture. The load ramp is deployably coupled to the closure panel. The load ramp includes a coupled end and a free end. The load ramp is movable between a retracted position and an extended position. The moisture sensor is positioned proximate to the free end of the load ramp. Methods of controlling the vehicle are also disclosed.

Disclosed is an operator for a garage door including one or more cameras. The operator consists of a motor, a traction mechanism connected with the motor, a door connected with the traction mechanism, wherein operation of the motor causes the traction mechanism to open and/or close the door and wherein the door is located in a doorway, a controller operatively connected with the motor to open and close the door, an imaging system connected with the controller and positioned to collect image data, and a communication system connected with the controller, the communication system adapted to send data, including image data, from the controller and to communicate command signals to the controller, wherein image data is sent to a remote user device and command signals are received from the remote user device. The controller is also connected to one or more lock actuators that can lock and unlock the garage door as well as one or more man doors. Image data is used to control operation of the door, to lock and unlock the door in response to event, such as the delivery of a package, and lock and unlock the man doors to allow access to a dwelling and to secure the dwelling.

The invention relates to a method of monitoring an electromechanical actuator system, the method comprising the steps of estimating the voltage drop in the power supply to the motor associated with defects of the inverter by means of a Kalman filter, estimating (300) at least the electromagnetic torque coefficient of the motor by taking account of the estimated voltage drop, and calculating (400) the electromagnetic torque of the motor from the electromagnetic torque coefficient of the motor.

Embodiments of a system and method for controlling a door are generally described herein. A door opener system can include a head unit. The system can include a wall station, a controller, or a wireless transmitter. The wall station can be inside a room, the room including the door and the controller can be outside the room. The wireless transmitter can be portable. The wall station, controller, or wireless transmitter can be used to control the head unit. The head unit can be used to open or close the door.

A sensor for position determination of a drive system comprising: a magnetic sensor adapted to determine the rotational position of a magnet linked to the drive system; at least one Hall sensor to determine rotational movement and direction of rotation of the magnet; a microcontroller unit for evaluating data of the magnetic sensor and of the Hall sensor; and a rechargeable battery connected to a power supply of the sensor and that represents an alternative power supply, wherein, on a failure of the power supply, the sensor is adapted only to supply the Hall sensor and the microcontroller unit with energy from the rechargeable battery when the Hall sensor does not detect any rotational movement of the magnet and to supply at least one further component of the sensor with energy from the rechargeable battery when the Hall sensor detects a rotational movement of the magnet.

A system for moving an aircraft door from an open position towards a closed position. The system includes an aircraft door actuator, an input receiving primary power from a primary power supply to power movement of the aircraft door from the open position towards the closed position, a secondary power supply to power the aircraft door actuator to move the aircraft door from the open position towards the closed position, and a controller configured to cause the secondary power supply to power the aircraft door actuator to cause the aircraft door actuator to move the aircraft door from the open position towards the closed position, on the basis of a determination that insufficient primary power is available from the primary power supply via the input to move the aircraft door from the open position towards the closed position.

The present invention relates to a door operator with an abnormal voltage protection function and a method for abnormal voltage protection of a door operator. According to the present invention, before a door operator motor is electrically energized by an external power source, a controller determines whether the external power source meets the rated voltage of the door operator. In the case that the external power source meets the rated voltage, the controller activates the door operator motor; in the case that the external power source does not meet the rated voltage, the door operator motor is deactivated, and the controller issues a warning.
