A pivot structure as part of a framework for temporarily suspending equipment such as a movie screen from a ceiling track can include an oblong beam adjustably mounted to the track. The pivot structure can include a housing having a cylindrical bearing for rotatively mounting a spindle. A pair of separately actuatable brakes can clamp the spindle in a locked position. Each brake can include a barrel having a concavity in its outer cylindrical surface which when driven against the spindle discourages its rotation.

A display mounting bracket includes a horizontal mounting arm and a mounting plate, a vertical bottom mounting arm, and a vertical top mounting arm attached to the horizontal mounting arm. The vertical bottom mounting arm is movable and positionable at multiple positions along a longitudinal axis of the horizontal mounting arm. A first display bracket is attached to a first end of the vertical bottom mounting arm and a second display bracket is attached to a first end of the vertical top mounting arm. A first compression pad is movably secured to the vertical bottom mounting arm and a second compression pad movably secured to the vertical top mounting arm.

An adjustable writing board includes a planar member having a front face, a rear face opposed to the front face, two side edges slidably engaged with a first station and a second station respectively; a selective third station slidably engaged with a middle portion of the planar member; a selective remote control panel electrically connected with the first station, the second station, and/or the third station to control operations thereof; wherein each of the first station, the second station, and/or the third station comprises a locking mechanism having a slide guiding rail, a wheel roller slidably received in the slide guiding rail, and a plurality of stoppers, which can retract and contract to block and release the wheel roller.

Elastomeric holders in the form of toiletry holders, mirrors holders, shower caddies and make-up holders are provided. The holders comprise a body, having a substantially planar rear surface, configured to releasably adhere to a vertical surface without the use of adhesives, and a retainer, for retaining an item and formed at least in part by the body, such that a front surface of the body forms a peripheral edge around the retainer.

A mounting apparatus (1) to mount a flat video screen, forming part of a video wall, to a support comprises a front frame (2) to carry the video screen, and a rear frame (3) to mount to the support, connected by a pair of scissor mechanisms (6). The mounting apparatus (1) has a closed configuration in which the scissor mechanisms (6) are closed and the front (2) and rear (3) frames are close together, and an open configuration in which the scissor mechanisms (6) are open and the frontal frame (2) is spaced away from the rear frame (3). A tension spring (18) is mounted across one scissor mechanism (6), urging it open and biasing the frames (2,3) apart into the open configuration. A series of latch elements (15,16) mounted to the frontal (2) and rear (3) frames engage when the frames (2,3) are pushed together into the closed configuration, holding the frames (2,3) together, but then release when the frames (2,3) are again pushed together, allowing the tension spring (18) to drive them apart. To avoid too rapid and jerky movement, a damping mechanism (21) is provided to regulate the motion of the scissor mechanisms (6) and the frames (2,3). Thus, the flat video screen on the frontal frame (2) forms part of the video wall when the mounting apparatus (1) is latched closed, but the mounting apparatus (1) is easily unlatched and opens, such that the frontal frame (2) and video screen move smoothly and safely forwards out of the video wall, for maintenance or replacement of the video screen.

A mobile device holder comprising a backing panel and a basket portion, the backing panel has a selectively attachable mounting panel assembly adapted to detachably secure the mobile device holder to a vertical mounting surface, the basket portion projects forwardly from the backing panel and is adapted to receive and retain a mobile device and mate said mobile device with a charging plug. A contiguous modular arrangement of multiple mobile devices positioned in a column configuration allows multiple mobile devices to be stored, while the basket portion is tilted forwardly to prevent the obstruction of basket openings when the mobile device holders are vertically stacked in the column configuration.

A lightboard system providing the multiple advantages required by presenters to audiences. Wheels support and render mobile a base. Supported by the base, a frame defines an opening and includes pairs of vertical struts and corresponding vertical tubes, the tubes sliding along the struts in a telescoping movement to raise and lower the frame height. A clear screen is fixed within the opening; the height of the screen is adjusted as the frame telescopes. The screen has a front face displaying content from presenters and an opposing rear face, and induces paths for and scattering of light to highlight the content. A dimmable light source is embedded in the frame and illuminates the screen. Attached to a telescoping mount on the frame, a video camera is directed toward the rear face, streams or records the content to create images, and automatically flips the images for viewing by audiences.

A workspace system includes different base components, different accessory interfaces and different accessories. Different accessory interfaces may be fixed to different base components, and different accessories may be releasably engaged by different, or the same accessory interfaces. The same accessories may be engaged by different accessory interfaces. The base components and accessories may be reconfigured to define different workspaces. Methods of assembling and reconfiguring the workspaces are also provided.

The present disclosure provides a method and a device for adjusting display of a multimedia blackboard, a medium, and an electronic device. The method includes: obtaining brightness simultaneously acquired by a plurality of light sensors of the multimedia blackboard; analyzing the brightness and perform a smooth processing to generate a first brightness distribution image; obtaining a next frame display image and a backlight brightness of a display device; adjusting a pixel color attribute value of a frame pixel in the next frame display image and/or the backlight brightness according to a preset visual adjustment information, the first brightness distribution image, the next frame display image, and the backlight brightness.

A mounting apparatus for positioning a television relative to a wall and a fireplace mantle includes a mounting plate coupled to a distal end of a positioning arm and is moved and positioned according to movement of the positioning arm. The positioning arm has a linear configuration with a proximal end mounted inside a wall housing which is itself mounted into a wall above the mantle of a fireplace. The positioning arm is pivotally movable between a retracted configuration completely inside the wall housing and a deployed configuration outside and extending away from the wall housing sufficiently that the plate (and television attached to the plate) is forward of and then below the outwardly extending mantle. The mounting plate is operable to tilt outwardly so as to clear the mantle and to swivel side to side at the viewing discretion of a user.
