A device for determining the position of a rear door or liftgate of a cargo truck or trailer includes a base attachable to the rear door or liftgate. A visual indicator extends from the base so as to be viewable from a side view mirror of the truck to enable a driver of the truck to determine the position of the rear door or liftgate due to the position of the visual indicator. The visual indicator may be a plurality of closely spaced apart elongated members, which may be brightly colored or light transmissive so as to be easily seen.

A metal cabinet with electrically conductive hinges comprises a cabinet body and a cabinet door that are made of an electrically conductive metal. An LED luminous body is disposed in the cabinet door, and at least two electrically conductive hinges for enabling the cabinet door to rotate relative to the cabinet body are disposed between the cabinet door and the cabinet body. Each of the hinges comprises a first hinge body and a second hinge body. The first hinge body is connected to a first electrically conducts wire connecting the first hinge body to a power supply. A first outer insulation pad is disposed between the first hinge body and the cabinet body. The second hinge body is connected to a second electrically conductive wire connecting the second hinge body to the LED luminous body. A second outer insulation pad is disposed between the second hinge body and the cabinet door.

A display case door assembly for a temperature-controlled storage device includes a vacuum panel, a hinge rail, and a lighting element. The vacuum panel includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap provides thermal insulation for the vacuum panel. The hinge rail is coupled to an edge of the vacuum panel and configured to rotate along with the vacuum panel between an open position and a closed position. The lighting element is coupled to at least one of the edge rail and the vacuum panel and configured to emit light toward an interior of the temperature-controlled storage device when the hinge rail and vacuum panel are in at least the closed position.

A window assembly includes a first polarizing windowpane, and a second polarizing windowpane. The first and second polarizing windowpanes are each independently moveable between a first position that blocks an opening to an interior of a vehicle, and a second position that does not block the opening. A window operating method includes moving first and second polarizing windowpanes of a window assembly from respective first positions that block an opening to an interior of a vehicle to respective second positions that do not block the opening.

A method and device for opening a door in a hygienic manner, is done by positioning a foot or hand in a specific defined area so that a light beam that is directed towards the area is interrupted within a set range of distances such that an automatic opening mechanism for the door is activated.

An embodiment can include a lamp safe system that includes an inner casing and an outer casing, lampshade or lamp body, which can be removably attached to an outer casing though a outer body attachment device. An inner casing can include a first wall, second wall, and third wall that can be removably attached to a safe door. An inner casing can have a male flange. A inner casing can have a door with a lock removably attached. An outer casing can substantially surround an inner casing. An outer casing can have a female flange. An outer casing can have an air spring attached to it through a clevis, which can be attached to an inner casing. A inner casing can slide on alignment track which can be attached to both an inner casing's first wall and third wall, and outer casing inner surface. An electrical system can provide a user with information on a lamp safe system.

A modular garage door opener system and method including a garage door opener having a motor that is configured to be coupled to a garage door to open and close the garage door. The garage door opener includes a first accessory port including a first accessory mounting interface and a second accessory port disposed on the garage door opener including a second accessory mounting interface. An accessory device including a first mounting interface engages the first accessory mounting interface to couple the accessory device to the first accessory port. The accessory device may be disengaged from the first accessory mounting interface and then engage the second accessory mounting interface to couple the accessory device to the second accessory port. Additionally, a second accessory device may engage the first accessory port after disengagement of the accessory device.

An access door may include a core, first and second stiles defined along opposites sides of the core such that the core between the first and second stiles defines a recessed pocket with each of the first and second stiles defining a channel therein extending longitudinally along an inwardly-facing edge thereof, bottom and top elongated panels each defining tongue members at opposite sides thereof and configured to be received transversely in the recessed pocket with the tongue members received within the channels defined along the inwardly-facing edges of the first and second stiles, wherein, with the top and bottom elongated panels received in the recessed pocket, exterior faces of the first and second stiles, exterior faces of the top and bottom elongated panels, and an exposed surface of the recessed pocket between the top and bottom elongated panels define an exterior surface of one side of the door.

A system for adjusting a closure element of a vehicle comprises an adjustment drive for adjusting the closure element relative to a vehicle body of the vehicle between a closed position and an open position, a control device for actuating the adjustment drive for executing an adjusting movement of the closure element between the closed position and the open position, and a light generating device for generating a light signal. The control device is configured to actuate the light generating device for generating a first light signal during an adjusting movement of the closure element and for generating a second light signal when the closure element is in the open position.
