A flat-type ventilation door-window structure includes a frame (1), a first movable sash (2) and a second movable sash (3). The first movable sash (2) and/or the second movable sash (3) can slide up and down in an opening (11) of the frame (1). A first guide device (300) and a second guide device (400) being respectively provided between the first movable sash (2) or the second movable sash (3) and the frame (1). The first guide device (300) and the second guide device (400) can guide the first movable sash (2) or the second movable sash (3) to change the sliding path. The flat-type ventilation door-window structure can block outdoor sound, rain and air, and improve sound insulation, water tightness and air tightness.

A system and method are provided for automated engaging of a truck trailer at a loading dock. Sensors measure a distance and an angle of alignment between the incoming trailer and a wall of the loading dock. An outside lighting system guides a truck driver backing the trailer toward the dock door. A vehicle restraint system fixates the trailer within the loading dock in response to signals from the sensors. An overhead dock door opens once the trailer is successfully fixated by the vehicle restraint system. A dock leveler deploys after the overhead dock door opens. An inside dock light indicates to dock personnel that the trailer is ready to be serviced. Once servicing of the trailer is finished, an automated release of the trailer from the loading dock may be initiated by PLC communication.

The invention relates to a sheath stop including: a hole through which a window lift cable is to pass; and a sheath abutment for locking the sheath of the window lift cable on one side of the sheath stop and wherein, on the other side of the sheath stop, the sheath stop includes a shaft provided so as to be mounted onto a bracket of the sheath stop such that the sheath stop has a freely rotatable mounting configuration on the bracket. The shaft extends transversely to the main orientation of the passage hole, and the passage hole has a partial side clearance that allows the cable a degree of bending freedom within a plane perpendicular to the shaft when the sheath stop freely pivots about the shaft.

A window frame has a sash and a panel that is disposed parallel to the sash, both of which are slidably disposed in the frame. A receiver is fixed at a first end of the frame. When the sash is in a first position, the sash is disposed within the receiver. When the sash is in a second position, the sash is disposed outside the receiver. A motor is fixed relative to the frame with a drive system connecting the motor to the sash or the panel. A control input is connected to the motor and is configured to receive a signal from a controller, a sensor, or a building management system.

One embodiment of a deployable structural system having sandwich-like shell stiffness and strength properties constructed of an outer elastic sheet (11) and an inner elastic sheet (12) connected by a plurality of parallel elongated substantially rigid webs (13) wherein hinges (14) constitute the connections. The hinge connection spacing dimensions on the inner and outer elastic sheets are differing such that the resulting assemblage may be elastically bent into a compact cylindrical configuration. Deployment is achieved through reversal of the bending process and application of sufficient external supports such that the deployed configuration is statically stable. Additional embodiments are described.
