A system is used to control access into a vehicle having a vehicle body defining a vehicle interior, a vehicle exterior, and an access opening. The vehicle also has an access door for selectively covering and uncovering at least a portion of the access opening. The system includes a latch configured to selectively fasten the door to the vehicle body and release the door therefrom. The system also includes a cable configured to operate the latch and thereby release the door from the vehicle body. The system additionally includes a door presenter configured to shift the door away from the vehicle body. The system also includes a mechanism configured to sequentially actuate the cable and the door presenter. The system further includes an electric motor configured to power the mechanism such that the door is shifted away from the vehicle body by the door presenter after the door is released.

A door safety system (3) for a door (2), having a safety component (10) arranged on a movable door element (4, 4a, 4b) of the door (2) and a supply component (11) arranged on a stationary door frame (5) of the door (2) for supplying energy to the safety component (10). The safety component (10) has an electric energy store (12) which is designed to autonomously supply electric energy to the safety component (10) when the door (2) is open, and the safety component (10) and the supply component (11) are designed to electrically charge the electric energy store (12) of the safety component (10) when the door (2) is closed.

The present invention provides an automatic animal door system. The automatic animal door system includes an animal door module, a linear motor driver and a control module. The animal door module includes a door and a frame having an opening, and the door is lively connected with the frame and configured to move between a closed position covering the opening and an open position away from the opening. The linear motor driver is connected with the door and configured to drive the door move between the closed position and the open position. The control module is electrically connected the linear motor driver and includes a processor and a non-volatile memory storing a programmed set of instructions. The processor executes the programmed set of instructions to control the linear motor driver open or close the door.

The present application provides a touch-free door driving device initiated upon the affirmative action or command of a user. More specifically, a user a door driving device is provided which can open the door when the user is at a distant location and is approaching the door. This apparatus can be easily installed on either side of the door which is user friendly and easy installation with minimal steps such as anyone can install it at any door of any room. Additionally, in spite of the door thickness, the apparatus can be installed without drilling or using any sort of tool. Preferably, the door driving device is provided with sufficient pull and push torque without any stoppage.

Systems and methods are provided for protecting a door system from damage by a back electromotive force (EMF) voltage generated when a door coupled to a door actuator is manually closed. The door system may include a driver configured to drive the door actuator to move the door, and a back EMF protection circuit. The back EMF protection circuit detects a back EMF voltage generated by the door actuator when the door is moved, and determines whether the back EMF voltage exceeds an overvoltage threshold. In response to determining that the back EMF voltage exceeds the overvoltage threshold, the back EMF protection circuit causes the driver to transition to an enabled state to short the back EMF voltage to ground.

A device for identifying and monitoring the state of an arrangement to be monitored having an openable and closable wing element is provided. The device has a housing, which has a housing base securable on or connected in one piece to the arrangement and a second housing part attachable to and removable from the housing base. The device is also provided with an identification marker, the housing base has a first identification marker for the arrangement to be monitored having an openable and closable wing element, and the second housing part has at least one second identification marker identifying the second housing part.

A sliding door driving device includes: a power source; a motor that outputs power to open and close the door; a motor driving circuit that connects the power source and the motor to each other; and a motor control device that controls the motor driving circuit. The motor control device includes an inverter that converts DC power supplied from the power source into AC power, and a shunt resistor disposed between the power source and the inverter. The position detection unit of the motor control device obtains the rotation angle of the motor based on the output of the shunt resistor.

An apparatus comprises a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; a closing mechanism coupled to the base plate and configured to be coupled to a hinge of the door and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein in the unprimed state the closing mechanism is decoupled from operation of the door; and in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal.

A system including a sensor supported by a motor vehicle, the sensor configured to send a first signal corresponding to an obstacle within a proximity of a door, an electronic control unit configured to receive the first signal from the sensor, the electronic control unit configured to send a second signal based upon the first signal, the second signal being capable of controlling operation of the door, an energy source configured to power the sensor and the electronic control unit independent of whether the motor vehicle is in an on condition or an off condition, and wherein the sensor sends the first signal and the electronic control unit sends the second signal to control operation of the door when the sensor detects an obstacle within proximity of the door.

A modular electronic deadbolt includes a bolt module having a first housing defining a first longitudinal axis, a motor disposed in the first housing, and a deadbolt configured to be linearly moveable in relation to the first housing along the first longitudinal axis by the motor. The modular electronic deadbolt also includes a battery module configured to be operatively coupled to the bolt module. The battery module includes a second housing configured to receive a power source, and a face plate coupled to the second housing. The faceplate defines a second longitudinal axis and includes an extension that extends along the second longitudinal axis. The extension is configured to removably couple the bolt module to the battery module such that the first longitudinal axis is substantially orthogonal to the second longitudinal axis.
