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 garage door opener system having a garage door opener and a remote input device electrically connected to the garage door opener by an electrical conductor. The remote input device receives power by the electrical conductor. The remote input device includes a device controller to communicate an event message, monitor for an acknowledgement message within a time period, and repeat the event message when the acknowledgement message is not received within a time period. The garage door opener includes a master controller. The master controller receives the event message and communicates the acknowledgement message in response to receiving the event message. Also disclosed is a method of operating the garage door opener system.

The present disclosure provides a barrier operator system in which a remotely located transceiver type controller is in wireless communication with a transceiver type adapter connected to a barrier operator, and in electronic communication with the barrier operator's microcontroller. The controller is operable to wirelessly transmit door operator status inquiries to the adapter. This may be effected automatically in connection with the transmission and receipt by the adapter of door toggle commands or separate and apart from same. The status information is wirelessly transmitted by the adapter in broadcast form without source or destination address to the remote device in a signal that is non-addressed broadcast door operator (and, indirectly, door) status information by relying upon the receipt of the message by the remote within the specific time limit of the reception window of the remote.

The hinge assembly comprises a housing for mounting on a cabinet and a post member for mounting on a door and for rotation relative to the housing. A first electrical contact is mounted within the housing for connection to a source of electrical power in the cabinet and a second electrical contact is disposed in the post in electrical contact with the first contact for connection to an electrical appliance in the door. In one embodiment, the electrical contacts rotate relative to each other as the post member pivots on the housing while in other embodiments; the electrical contacts remain stationary relative to each other as the post member pivots on the housing.

The invention relates to an enclosure for a drive unit (1) for the automation of a garage door, wherein the drive unit (1) includes a connection to a drive track (4), which is provided with revolving force transmitting means (19), the enclosure as a two-part housing consists of a lower housing part (2) and an upper housing part (32, 54), wherein the lower housing part (2) includes a straight planar housing underside (37) the border areas (15) thereof being provided with roundings (8) and thereto adjoining essentially straight lateral sections (9), and in that the upper housing part (32, 54) is fitted onto the lateral sections (9), wherein the exterior contour includes transitions (11), which are configured as curved extensions, which merge into a straight housing back side (7), which is configured essentially parallel to the housing underside (37), wherein the surface content of the housing back side (7) is smaller than the surface content of the housing underside (37).

An electronic motor vehicle sensor unit includes a housing, a control and evaluation device arranged in the housing, and at least one capacitive sensor electrode with a detection region (X, X). The capacitive sensor electrode is coupled to the control and evaluation device and is arranged in the housing. The sensor unit further includes a lighting device with an illuminant that can emit an optical signal, wherein the lighting device is coupled to the control and evaluation device, and a target region (Y) identifying the detection region (X) can be marked outside the housing with the lighting device. The housing, the control and evaluation device, the at least one capacitive sensor electrode and the lighting device form an integrated assembly.
