A mobile device display stand structure includes: a shaft driven and rotated by applying a critical moment greater than a resistance of the shaft to overcome the resistance of the shaft; and a first lever and a second lever connected to the shaft separately. The first lever and the second lever use the shaft as a fulcrum and flip over relative to each other by the shaft to define an included angle, and the first lever and the second lever are plate-shaped bodies. When the included angle is 0-180 degrees, the gravity of the first lever generates a first moment relative to the shaft or the gravity of the second lever generates a second moment smaller than the critical moment relative to the shaft, such that the first lever or the second lever cannot be rotated relative to the shaft and the included angle is kept constant.

Deployable stands are described for holding a book at an angle relative to a tabletop. The deployable stand can have a cover panel with a deployed pocket and a folding assembly with three panels. The three panels can be rotatably hinged in series to the cover panel. The deployed pocket can be for fitment with the folding assembly to maintain a deployed position. The three panels can form a base for holding the book at an angle relative a tabletop in the deployed position.

A stand for use with a laptop or portable computing device, such as, but not limited to, a MacBook. The stand elevates a laptop or portable computing device up off a desk or table top, reducing neck strain in the user and creating a more comfortable work setting. An adjustable-height stem connects a base and platform. The base also may be used alone, and comprises means for support the bottom of a computer stand. The base also may comprise storage space or shelves.

A multi-use exercise apparatus and methods of using same is disclosed. The multi-use exercise apparatus and methods of the invention may provide a means for performing both counter or standing push-ups and/or floor push-ups. The multi-use exercise device may include a base member or portion, a foot member or portion, and a hand member or portion. Further, a method of using the multi-use exercise apparatus is provided.

Disclosed are a reading support apparatus which can detect a user input (touch and/or drag) conducted on a real book by using one camera, and a user input detection method using the same. The reading support apparatus sets a finger and/or nail on a target surface image captured through one camera to touch recognition reference, detects, as a user input, a user's touch or drag conducted on the surface of the real book by comparing the finger and/or nail included in the target surface image to the touch recognition reference, and provides an action corresponding to the user input.

A system for positioning of a viewable item includes a base, an extendable arm moveably connected to the base, a device plate connected to the extendable arm, and a retainer connected to the device plate and the item.

Disclosed herein is an adjustable stand for supporting objects on the adjustable stand, in accordance with some embodiments. Accordingly, the adjustable stand comprises a bottom plate, a middle plate, a top plate, a toggle mechanism, and an actuating device. The toggle mechanism allows pivoting of the top plate in an unlocked state and restricts the pivoting in the locked state. The actuating device transitions the toggle mechanism to the unlocked state by receiving a first actuating input and transitions the toggle mechanism to the locked state by receiving a second actuating input. The toggle mechanism transitions to the unlocked state from the locked state based on applying a pivoting force on the top plate above a threshold pivoting force without receiving the first actuating input. The toggle mechanism transitions to the locked state from the unlocked state based on releasing the pivoting force applied to the top plate.

A supinely reading stand which barely blocks the text of the book, barely interferes with the sight of the eyes, and is more simply constructed, easy in assembly and lower-cost. The supinely reading stand comprises a book-supporting structure. The book-supporting structure comprises a four-sided frame and at least one tension-resistant thin line distributed in the inner area of the four-sided frame. The four-sided frame includes first opposite sides and second opposite sides. The tension-resistant thin line(s) is/are connected to the first opposite sides of the four-sided frame in tension state.
