Abstract: An automated window mechanism 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 detecting the external force while the electric motor is in the locked state, the positive lead and the negative lead are grounded, rendering the electric motor an electric brake. A method and system for preventing unwanted movement of an automated window are also disclosed.

Abstract: An automated window mechanism includes a motor attached to a sliding window and a rack on a window frame. A transmission couples the motor to the rack such that rotation of the motor causes the transmission to move the sliding window relative to the rack. The mechanism also includes a clutch switch assembly, that includes a switch and a clutch actuator responsive to the switch and being configured to engage and disengage the motor to the rack. The mechanism also includes a position sensor coupled to the transmission and configured to monitor a position of the sliding window relative to the frame using the transmission. The position sensor continues to monitor the rotational position of the transmission when the transmission is engaged and when the transmission is disengaged.
