An exemplary method relates to operating a door closer assembly including a closer body, a pinion rotatably mounted to the closer body, a motor including a motor shaft, and a bidirectional clutch connected between the pinion and the motor shaft. The method generally involves permitting, by the clutch, rotation of the pinion in each of a first direction and a second direction without transmitting rotation of the pinion in either direction to the motor shaft; sensing, with a sensor, a rotational position of the pinion; comparing, by a controller, the rotational position of the pinion with a desired rotational position; based upon the comparing, driving the motor to rotate the motor shaft; and by the clutch, coupling the motor shaft with the pinion in response to rotation of the motor shaft, thereby transmitting torque from the motor shaft to the pinion and urging the pinion toward the desired rotational position.

A power supply apparatus for a door glass for a vehicle that includes the door glass installed on a door of the vehicle and configured to be movable in an upward and downward direction is provided, wherein an operation module is installed on the door glass to use power, and a power source part is installed on the door. The power supply apparatus includes a rail installed on the door and provided with a rail terminal to electrically conduct with the power source part, and a slider provided with a contactor slidably contacting the rail terminal and electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass, wherein the contactor and the rail terminal maintain an electrically conductible state at all times regardless of a change in a position of the door glass.

A system for use with an autonomous working machine such as a robotic lawn mower. The system may allow communication (directly or indirectly) between the machine and a gate or other barrier opening to allow unattended or remotely-controlled passage of the machine through the gate. In some embodiments, the mower may include a vision system operable to detect unknown objects within an area adjacent to the gate.

A device has at least two components that can be moved relative to each other. A drive device is provided with a drive housing and a drive shaft in order to bring about a relative movement of a first component to a second component. If the drive shaft is coupled in a rotationally fixed manner to the second component, the drive housing is rotatably accommodated on one of the two components and can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom. If the drive housing is coupled in a rotationally fixed manner to the second component, the drive shaft can be coupled by an actuator in a rotationally fixed manner to the first component and can be decoupled therefrom.

A locking device is proposed to lock and/or to unlock a movable closure element like a door, a lid, etc. in a lockable object like a building, a ship, a vehicle, a train or the like, wherein the locking device has an electric control unit and/or a drive unit to control and/or to drive a movement of the movable closure element. The locking device shall be usable in applications without a handle for manual movements and is working with disconnected regular power supply. According to the invention, at least one supercapacitor is provided to store energy for operating the locking device in an emergency case.

An actuator and a vehicle operation system with the actuator. The actuator includes a housing unit composed of a combination of internal components including a motor, a housing and a cover. A pair of terminals conveys external power to the motor. A terminal holder holds die pair of terminals. The terminal holder is accommodated in the housing unit as a sub-assembly separately from the housing unit.

An opening/closing body control device may include an actuator, a drive device configured to drive the actuator configured to at least one of open and close an opening/closing body of a vehicle, an operation switch, and a signal output device. The signal output device may be configured to drive the actuator via outputting a signal to the drive device when the operation switch is operated. The signal output device may include a signal line, a submergence detection circuit configured to detect submergence of the vehicle in water, a switch, and a pullup resistance connected via the switch to a power source. The switch may be configured to turn on when submergence of the vehicle in water is detected and the operation switch is not operated. The pullup resistance may be connected electrically to the signal line when the switch turns on to output a signal to the drive device.

The present disclosure provides a structure configured to preset an automatic positioning duration to enable hinge blades to be automatically closed, the structure two hinge blades, a threaded sleeve, a fixed rod, a first spring, a electromagnet suction disk, a DC power supply electromagnet, a DC power supply timing controller, a remote control, a plug, and an adjusting base. The two hinge blades are configured to rotate relative to each other, each of the two hinge blades comprises a shaft sleeve and a blade fixed on an outer side of the shaft sleeve, the fixed rod comprises a threaded rod, the threaded sleeve comprises a transmission rod fixed in the shaft sleeve of the two hinge blades, the plug is fixedly disposed in the shaft sleeve of the two hinge blades, the threaded sleeve is separated from the plug, and the fixed rod, the first spring, the electromagnet suction disk, the power supply electromagnet, a bearing, and the adjusting base are disposed between the threaded sleeve and the plug disposed in the shaft sleeve of the two hinge blades. When the hinge blades reach the automatic positioning time preset by the timing controller, so that the hinge blades synchronously cooperates with the demagnetization time point preset by the timing controller. At the same time, the elastic force energy storage of the first spring changes and releases. An application of the present disclosure is wide, and has good industrial applicability.

Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).

A power supply apparatus for a door glass for a vehicle that includes the door glass installed on a door of the vehicle and configured to be movable in an upward and downward direction is provided, wherein an operation module is installed on the door glass to use power, and a power source part is installed on the door. The power supply apparatus includes a rail installed on the door and provided with a rail terminal to electrically conduct with the power source part, and a slider provided with a contactor slidably contacting the rail terminal and electrically conduct with the operation module, while moving in the upward and downward direction integrally with the door glass, wherein the contactor and the rail terminal maintain an electrically conductible state at all times regardless of a change in a position of the door glass.
