A power-supply control system includes: a lock control unit that controls a door-lock device; and a travel control unit that controls a travel operating unit related to either driving the power of the vehicle, braking the vehicle, or steering the vehicle. A lock high-level control unit, in a state in which supply of electric power to the lock control unit, the travel operating unit, and the travel control unit is stopped, while the first trigger signal is not outputted from an operation unit, makes electric power not be supplied from a power supply to the lock control unit, the travel operating unit, and the travel control unit, and when the first trigger signal is outputted, starts to supply electric power from the power supply to the lock control unit and the door-lock device and makes the lock control unit execute control to unlock the door-lock device.

A security door configured to provide controlled access through a doorway wherein the security door of the present invention includes all elements to offer a touch-less entry and further provide compliance with building codes and visual surveillance. The security door of the present invention includes a door member being hingedly mounted on a doorway. The door member includes an integrally mounted controller that is operably coupled to a communications network via a network module and communications cable. The controller is operably coupled to a card scanner module and a switch module that operate to provide verification of an individual and move the door member to an open position. The door member further includes an integrally mounted power supply and at least one camera module wherein the camera module is operable to capture photographic images. A light module and egress module are integrally mounted to the door member.

An intelligent window allowing ventilation has an outer frame, a sliding frame, an upper locking rod, a lower locking rod, a driving module, a power supply module, and a switch assembly. The sliding frame is slidably mounted in the outer frame. The switch assembly controls the driving module to selectively drive the upper locking rod and the lower locking rod to two locking positions respectively, two ventilation positions respectively or two unlocking positions respectively. Since no handle is needed, an appearance of the intelligent window is neat and scenery outside the intelligent window would not be sheltered. In addition, by actuating the switch module to electrically drive the upper locking rod and the lower locking rod, a user is able to switch the intelligent window to a locked state, a ventilation state or a unlocked state. It is labor-saving and simple in operation.

A driving device includes a motor and a control unit for controlling of the motor. The motor includes a motor body and an end cap assembly disposed at one end of the motor body. The motor body comprises a stator, a rotor rotatable relative to the stator, and a motor shaft fixed to and rotated with the rotor. The end cap assembly is provided with two brushes. The control unit includes two connectors for connecting with an external power source. The two brushes are respectively electrically connected to the connectors through the control unit. Lengths of connecting routes of the two brushes to the corresponding connectors are substantially equal to each other.

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.
