A hinge of a computing device includes a primary support connecting a display to a stand. As the display rotates about the stand, the primary support slides along a friction strip, which stabilizes the display with respect to the stand. A stabilizer may connect the stand to the base or the stand to the display.

The hinge assembly includes: a rotating assembly and a hovering mechanism. The rotating assembly includes a first rotating part, and the first rotating part comprises a first guide groove extending obliquely around an axial direction of the first rotating part. The hovering mechanism comprises a sliding member and a position limiting member. The sliding member includes a protruding part, the protruding part extends into the first guide groove. The first rotating part drives the sliding member to move along the axial direction of the first rotating part when rotating. One of the position limiting member and the sliding member comprises a first limiting part, the other of the position limiting member and the sliding member comprises a second limiting part cooperated with the first limiting part.

A hinge assembly includes: a fixed supporting piece; a rotating assembly, movably connected with the fixed supporting piece and including a first limiting portion; and a locking mechanism, disposed on the fixed supporting piece and including a limiting piece which includes a second limiting portion matched with the first limiting portion. The fixed supporting piece slides relative to the rotating assembly in a direction perpendicular to an axial direction of the rotating assembly in a rotation process of the rotating assembly, so that the first limiting portion is connected with the second limiting portion or the first limiting portion is separated from the second limiting portion; when the first limiting portion is connected with the second limiting portion, the two limiting portions are matched with each other to limit rotation of the rotating assembly; when separated, limiting of the rotating assembly is released.

An electronic device is provided. The electronic device includes a first housing, second housing, a hinge structure rotatably connecting a side surface of the first housing and a side surface of the second housing facing the side surface of the first housing along a folding axis, a flexible display panel including a first display area, a second display area, and a third display area, and a supporting member supporting the flexible display panel. The supporting member includes a flexible region including plural openings having a length in a direction parallel to the folding axis, spaced apart from each other, and corresponding to the third display area, and rigid regions corresponding to the first display area and the second display area. Both ends of each of the openings partially overlapped on the plurality of gears are disposed outside the plurality of gears projected onto the support member.

A floor cleaning system having a flat headed mop is provided. The system includes a bucket having a plurality of compartments. At least one compartment is provided for cleaning the flat headed mop to remove dirt and debris accumulated during use. A second compartment is provided for recharging the mop pad with fluid. At least one wringer device is operably coupled to one of the plurality of compartments. The at least one wringer device having an extractor element to remove at least a portion of fluid from the mop pad.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.
