A garage door opener assembly, for opening and closing a garage door, including: a garage door, wherein the garage door is displaceable between open and closed positions; a motor, wherein the motor drives at least one of a screw shaft, a belt, and a chain and, in turn, a door opener arm secured to the garage door; a battery backup unit, wherein the battery backup unit includes a secondary electrochemical cell in electrical communication with the motor; and a kinetic energy charger, wherein the kinetic energy charger is in electrical communication with the secondary electrochemical cell.

A vertical door system includes: a door having a door frame, the door frame having at least one frame section; an operator; two vertical supports configured to: (a) be installable on opposite sides of the door opening and (b) support the vertical door, at least one of the vertical supports having: a guide track on a surface of the vertical support facing toward the door opening; and a drive system having: an elongated threaded rod drivable by the operator via a gearing arranged between the operator and the threaded rod; and one or more blocks, each block comprising a guide track connecting portion that connects to a guide track so the connected block is freely movable along the guide track, each block having a through-bore for accepting the threaded rod so that the block is positioned on the threaded rod and is movable along the threaded rod.

The invention relates to a system for opening and closing a window aperture, the system comprising: a moveable window panel; a pulley assembly coupled to the moveable window panel; a counterweight; and a pulley actuation mechanism. The moveable panel is heavier than the counterweight, the latter being attached to a first lateral side of the moveable panel via a first part of the pulley assembly. The pulley actuation mechanism is attached to an opposite lateral side of the moveable panel via a second part of the pulley assembly. The pulley actuation mechanism is switchable between energised and non-energised states based on one or more trigger events, between a closing mode whereby the pulley actuation mechanism retracts the second part of the pulley assembly thus imparting an additional closing force to the moveable panel sufficient to raise the moveable panel; and an opening mode whereby the pulley actuation mechanism is non-energised such that a passive opening force is imparted to the moveable panel by virtue of its weight to lower the moveable panel. A system for controlling a window system based on aircraft detection is also disclosed.

A threaded drum is rotated by a drive shaft. As the threaded drum rotates, part of a cable is wrapped around the drum, while at the same time, a second part of the cable is unwrapped from the drum. Rotation of the drive shaft is based on rotation of an operator.
