A rotatable suspension rail background system with multiple panels is an apparatus that maximizes the amount of background options in a studio area in an indoor or outdoor area for a photoshoot or video shoot. The apparatus includes track system and at least one background assembly. The track system defines a path for each of the plurality of background assemblies and guides each of the at least one background assembly across the studio area. The track system includes an upper main rail, an upper supplementary rail, and an upper raceway. The at least one background assembly provides various visual backgrounds for a photograph or video. More specifically, the apparatus further includes a first background sheet fixed across a first panel face of a support panel of the at least one background assembly. The apparatus further includes a second background sheet fixed across a second panel face of the support panel.

A profile learning system for cooperative control of a dual actuator applied to opposite sliding doors may include a first position sensor configured to detect a position of a door that operates in a first direction along a rail; a spindle assembly including a spindle that operates in a second direction with respect to the door to prevent the door from rattling; first and second motors engaged to the door and the spindle assembly and configured to provide driving power to the door and the spindle assembly, respectively; a memory unit configured to store the position of the door; and a control unit configured to adjust an output of the second motor configured for a predetermined time period and to determine learning success or learning failure for complete opening or closing of the door based on the position of the door when a stall state is detected due to a difference in stroke between the first motor and the second motor.

Lightweight, glidable shielded components (e.g. doors) may be used in conjunction with accredited enclosures to provide electromagnetic, acoustic and CBR protection.

In a sunroof device, each support member and each driving shoe include a pressing portion and an elastic body, respectively, that, when the driving shoe moves from a first position toward a second position, come close to each other and, when the driving shoe is positioned between the second position and a third position, come into contact with each other. When the driving shoe is positioned between the second position and the third position, the pressing portion presses the elastic body in a direction perpendicular to a width direction. A length in the width direction of the elastic body is longer than the pressing portion.

A trailer truck is the combination of a truck and one or more trailers used to haul freight. A trailer attaches to the truck via a trailer coupling (hitch), with much of its weight borne by the truck. The result is that both the truck and the trailer will have a distinctly different design than a rigid truck and trailer. Exemplary vehicles are provided, such as heavy duty trucks having truck bodies with improved aerodynamic characteristics, including improved drag coefficients.

A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (“HEMP”). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A barrier employed to keep children and/or pets in or out of certain areas in the house. The barrier includes four panels. Two main panels slide parallel to each other to lengthen or shorten the barrier as a whole. Two side panels stabilize the main panels and extend to the front and rear faces of the main panels to provide a self-supporting in-house barrier. Each of the panels includes a wooden frame. The wood lends less weight, less sharp edges, and more pleasing aesthetics than, for example, a metal gate. Legs are connected to the side panels to further stabilize the side panels and main panels.

A door for closing a chamber opening (4) in a chamber wall of a vacuum chamber (3) in relation to a surrounding space, in which the vacuum chamber is located, includes a door housing arranged in a surrounding space, a closing member (5) arranged in the surrounding space, and a rod (10), to which the closing member (5) is connected, wherein a first movement of the rod (10), through which the closing member (5) is displaced from an open position into an intermediate position, occurring in the form of a displacement of the rod (10) in the direction of the longitudinal axis thereof, wherein a second movement of the rod (10) subsequent thereto occurs in the form of a displacement of the rod (10) in a direction at an angle to the longitudinal axis thereof and/or in the form of a pivoting of the rod (10) about a pivot axis which is perpendicular to the longitudinal axis thereof, wherein the closing member is displaced from the intermediate position into a closed position via said second movement of the rod. The rod (10) is mounted in a moveable manner via the bearing elements, via the first movement thereof and via the second movement thereof in relation to the door housing, wherein the bearing elements are arranged in an inner space (30) of the door housing, which inner space is sealed with respect to the surrounding space or is connected to the surrounding space via a passage (41) extending through a housing wall (40) of the door housing, in which passage a particle filter is arranged. The rod (10) is guided out of the inner space (30) of the door housing into the surrounding space in a sealed manner.

A door system includes a track, a sidelite panel, and a slide panel. The track spans across a doorway having a clear opening defined by a trailing jamb and a lead jamb. The trailing jamb includes a jamb face facing the lead jamb. The sidelite panel is coupled to the trailing jamb by at least one swing clear hinge including a fixed portion and a revolving portion. The fixed portion is offset away from the lead jamb with regard to the jamb face. The slide panel is operable to move along the track. The slide panel has an open configuration when positioned in the track. The revolving portion is at least partially offset away from the lead jamb with regard to the jamb face when the slide panel is in the open configuration. The sidelite and slide panels are configured to pivot out of the header into a breakout configuration.

A cup holder assembly includes a door configured for translation between an open and a closed configuration, at least one receiver sidewall, and at least one first cup holder surface provided by a bottom surface of the door and configured to upwardly extend at least a portion of the receiver sidewall when the door is disposed in an open configuration. A retention system for a container is provided, including at least one container biasing member and at least one container supporting member. The container biasing member may be door-mounted or receiver sidewall-mounted.
