1. An automated window mechanism, comprising:
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 having a locked state in which locked state the electric motor and sliding panel are stationary, the electric motor having a positive lead and a negative lead; and
a monitor configured to detect an external force applied to the sliding panel while the electric motor is in the locked state;
wherein, 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, thereby rendering the electric motor an electric brake, thus impeding the external force from moving the sliding panel.
