An automated window mechanism is disclosed having an electric motor attached to a sliding panel of a window configured to open and close the window by moving the sliding panel. The electric motor has a locked state in which the electric motor and sliding panel are stationary. The automated window mechanism also includes a monitor configured to detect an external force applied to the sliding panel while the electric motor is in the locked state. In response to the monitor identifying the external force while the electric motor is in the locked state the electric motor opposes the external force to prevent unwanted movement of the sliding panel. A method and system for preventing unwanted movement of an automated window are also disclosed.

A movable barrier operator that includes a motor, an armature shaft of the motor, and a worm screw assembled with a distal end portion of the armature shaft. The movable barrier operator further includes a worm wheel engaged with the worm screw and a rotatable drive member connected to the worm wheel. Turning of the armature shaft and worm screw mounted thereto causes turning of the worm wheel and rotatable drive member.

An automated window mechanism having a motor and a force measuring component. A movement path is defined for the window movement relative to a window frame. The force-measuring component measures the force required to move the window along the movement path. The force required is stored as a force map and is a function of position along the path. Deviations from the force map cause the motor to take measures which may include stopping the motor.

An automated window mechanism has a motor that moves a sliding window along a frame to open and close the window. A position sensor, such as an encoder, monitors a position of the sliding window relative to the frame. The automated window mechanism can receive an instruction to calibrate to the frame by disengaging the motor while the position sensor remains engaged. The user then manually moves the sliding window between two end points and then reengages the motor. The position sensor records the end points, and then the automated window mechanism uses the end points as limits of movement for the sliding window.

A mechanism is disclosed for automating a sliding window having window components comprising a stationary pane component, a sliding pane component and a window frame component. The mechanism includes a telescoping mounting assembly attached to a first of the window components. The telescoping mounting assembly includes a housing and one or two extension arms, selectively extensible from the housing to either one or both sides of the first window component. A motor is disposed within the housing driving a first gear. Either one or two telescoping drive shafts are disposed within the extension arms, each having a gear on one end of the telescoping drive shaft driven by the first gear and having a gear on an opposite end of the telescoping drive shaft that engages a rack mounted on one side of a second of the window components. The telescoping drive shafts are coupled to the extension arms and are therefore selectively extensible with first extension arms. This mechanism is installed by extending the extension arm to fit the first of the window components. The sliding window is opened and closed by rotation of the motor and the telescoping drive.
