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 furniture drive system for a furniture part that is moveably mounted on a furniture body, includes a mechanical control unit having a pivotally mounted control arm for moving the moveable furniture part and at least one energy store for applying force to the control arm; an electric drive unit configured as a component designed to be separate from the mechanical control unit, and which has an electric motor for the electric motor-powered support of the movement of the moveable furniture part and a driver that can be driven by the electric motor for transmitting a torque of the electric motor to the mechanical control unit; and a damping device for damping the movement of the moveable furniture part. The damping device is arranged in the component of the electric drive unit for damping the movement of the moveable furniture part.

A transmission device for installation on a driveshaft, having a base body which encloses the driveshaft, a pinion which in the mounted state is arranged in the base body and on the driveshaft, and a rack which interacts with the pinion and runs through the base body. The transmission device is distinguished by the fact that the base body is open on one side in such a way that it can be fitted onto a driveshaft in the radial direction, and in that the pinion is in multiple parts such that it is possible to perform a mounting process on the driveshaft during which the parts of the pinion can be joined together by a radial movement with respect to the driveshaft.

An angularly variable device for use on a door having a closer piston with a piston arm wherein the angularly variable device is a protracting blocker comprised of a first section and a second section. Each section comprises a wall from which extends at least one tab extending perpendicularly therefrom. From the wall extends generally perpendicularly at least one but preferably a plurality of tabs so that the at least one tab on each of the first section and the second section rests on top of the piston arm. A retainer presses against an elbow joint forming part of the piston arm so as to firmly press the wall against the piston arm so that one side of the blocker is pressed against one side of the piston arm while the retainer presses against the opposite side of the piston arm so as to provide a secure installation of the blocker on the piston arm. A lever pivoted into a horizontal position presses the two sections together so that they remain in a given fixed position relative to each other so as to immobilize the piston arm in a given position.

A barrier operator feature enhancement device is designed to provide one or more features found in modern barrier operator devices and to incorporate those features into a previously installed barrier operator system. To facilitate ease of use, the barrier operator feature enhancement device can communicate with a large variety of barrier operators. Such communication may be wireless or wired, depending on the communication protocol implemented by a particular previously installed barrier operator. To facilitate the ease of installation, the device is designed to configure itself to operate with the communication protocol of the previously installed barrier operator. Once configured to be able to communicate with the previously installed barrier operator, the feature enhancement device works with the barrier operator to provide one or more additional features to enhance the capabilities of the previously installed barrier operator.

Devices, systems, and methods for a frame with a slidable segment are disclosed. The slidable segment is slidably mounted within the frame. A first motor is coupled to the slidable segment. The first motor has a first gear affixed to and driven by the first motor. A first gear track may be mounted to a first horizontal member of the frame, wherein teeth of the first gear align with tooth spaces of the first gear track. Rotating the first gear in a first rotational direction causes the first gear to pull the slidable segment in a first linear direction as the first gear walks along the first gear track. Rotating the first gear in a second rotational direction causes the first gear to pull the slidable segment in a second linear direction as the first gear walks along the first gear track.

The invention is systems and methods of operating a window with an automated window mechanism. The systems and methods include moving with the automated window mechanism a sliding panel of a window relative to a window frame to open or close the window. The sliding panel moves through a proximate closing zone. The method also includes in the proximate closing zone, operating the automated window mechanism in a limited state comprising at least one of reduced velocity, reduced current to the automated window mechanism, or reduced voltage to the automated window mechanism.
