An automated window mechanism has 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, or 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.

Disclosed is a hopper car gate assembly including a frame configured for attachment to a hopper car body. The frame defines an opening and includes a beam, wherein the beam has a slot formed therein. A stop plate is removably attached to the beam to selectively obstruct the slot. The assembly has a door supported by the frame. A stop block is attached to the door, wherein the stop block is located on the door such that when the door is inserted into the frame the stop block is aligned with the slot. With the stop plate attached to the beam, the stop block engages with the stop plate to define an open position and prevent further movement of the door in the open direction. With the stop plate detached from the beam, the stop block passes through the slot to allow removal of the door from the frame.

A tailgate assembly including a first gate and a second gate. The first gate configured to rotate with respect to a vehicle body and the second gate configured to rotate with respect to the first gate. The second gate includes an outer panel, an injection molded carrier plate, and a drive mechanism. The injection molded carrier plate is configured to be fixed the outer panel to form a cavity. And the injection molded carrier plate is configured to carry a number of functional components. The drive mechanism is fixed to the carrier plate and operably connected to at least one functional component of the number of functional components. Drive mechanism is configured to actuate and move the at least one functional component with respect to the second gate between the number of positions.
