A bearing assembly of a hinge coupling first and second components includes an outer ring secured to the second component having an axial primary bore with a primary inner surface. An inner ring axially rotates, and has a primary outer surface rollingly contacting the primary inner surface, defining a primary sliding path with a primary friction coefficient. The inner ring includes a secondary axial bore with a secondary inner surface. An inner shaft in the secondary bore is secured to the first component and is axially rotatable. The inner shaft has a secondary outer surface rollingly contacting the secondary inner surface defining a secondary sliding path with a second friction coefficient. One of the sliding paths has a triboelectric layer surface frictionally generating an electrical current when that sliding path is engaged. A transmission element transmits, to a failure detection system, a signal due to such electrical current.

A bush assembly configured to be disposed between a first component and a second component movably coupled to the first component, the bush assembly comprising a first bush portion comprising a self-lubricating material; and a second bush portion, the second bush portion having greater electrical conductivity than the first bush portion, wherein the second bush portion provides a conductive path between the first component and the second component.

A hinged corner for a construction form includes a first flange connected to a first mounting plate for a form member and a second flange connected to a second mounting plate for a form member. The first flange and the second flange pivot relative to one another in an overlapping relationship about a pivot point disposed between the first mounting plate and the second mounting plate.

A hinge is provided, which includes a V-shaped blade, an intermediate blade and a terminal blade. The V-shaped blade, the intermediate blade and the terminal blade are provided with holes to allow a fixed member to pass through; the V-shaped blade is hinged to one end of the intermediate blade for supporting the bending of a body; another end of the intermediate blade is hinged to the terminal blade for supporting the bending of the body; the strip-shaped grooves on the V-shaped blade, the intermediate blade and the terminal blade can be used to fix the hinge to a surface of the body using a belt or other fixed member, and to make the corrective member stably fix to one side of the body, effectively producing the lateral corrective force; the hinge design of each blade can coordinate the forward bending motion of the body, effectively introducing the corrective force.

A method for installing a multiple axis adjustable pivot bearing assembly, comprising: Installing and adjustment-pivot unit: using bolts or screws to install a pivot floor mount, comprising a pivot floor mount aperture and a slot, to a floor, sliding a pivot square nut with a pivot square nut aperture into the slot such that the pivot square nut aperture is aligned the pivot floor mount aperture, place a pivot cover, comprising a pivot cover aperture, over the pivot floor mount, such that the pivot square nut aperture, the pivot floor mount aperture, and the pivot cover aperture are aligned so as to receive a lower portion of a pivot bolt, installing the pivot bolt into the pivot square nut aperture and through the pivot floor mount aperture and the pivot cover aperture, such that a pivot disk, which is part of or assembled to the pivot bolt, is partially in a recess feature of the pivot cover, installing a height-adjustment nut onto an upper portion of the pivot bolt above the pivot disk, placing a pivot mount block onto the now assembled adjustment-pivot unit; and mounting a door onto the pivot mount block by attaching a door frame onto the pivot mount block.

An adjustment system comprising: a pivot nut comprising a pivot nut aperture feature configured to accept the lower portion of a pivot bolt; a floor mount having a slot in which the pivot nut is slidingly engaged so as to have, e.g., simultaneous movement including forward-backward, side-to-side and rotational and axial articulation, the floor mount having a floor mount aperture that aligns with the pivot nut aperture; and a cover configured to mount over the floor mount and engage with the pivot nut so as to move with the pivot nut.

An adjustment system comprising: a pivot mount block comprising an aperture configured to allow an upper portion of the pivot bolt to pass through the pivot mount block, the aperture having a lower radius greater than an upper radius so as to form ledge feature; and a bearing inserted in the aperture, wherein the ledge and a lower portion of the bearing is configured to rest on a pivot height-adjustment nut that is on the upper portion of the pivot bolt, or on a second bearing that rests on the pivot-height-adjustment nut on the upper portion of the pivot bolt, and wherein the upper portion of the pivot bolt extends out of the pivot mount block to pivotally support a frame that is mounted on the pivot mount block.

An adjustment system comprising: a pivot nut comprising a pivot nut aperture feature configured to accept the lower portion of a pivot bolt; a floor mount having a slot in which the pivot nut is slidingly engaged so as to have a movement including forward-backward, side-to-side and rotational, the floor mount having a floor mount aperture that aligns with the pivot nut aperture; and a cover configured to mount over the floor mount and engage with the pivot nut so as to move with the pivot nut.

A hinge assembly comprises first and second tape spring elements, wherein each of the spring elements is configured to connect a first element of a space structure to a second element of the space structure. Each of the first and the second tape spring elements is movable from a folded state into an unfolded state by releasing stored strain energy, to deploy the first and the second element of the space structure. The first tape spring element is connected to a first direct current source and configured to conduct direct current of a first polarity supplied to the first tape spring element from the first direct current source. The second tape spring element is connected to a second direct current source and configured to conduct direct current of a second polarity, opposite to the first polarity, supplied to the second tape spring element from the second direct current source.

A roller for a roller door has a roller bearing surrounded by a roller on the outer circumference and into which a bearing pin is inserted on the inner circumference, which protrudes in the axial direction from the roller bearing. The bearing pin has an inner part of a harder material and a bearing sleeve made of a softer material, wherein the inner part is pressed or screwed into the bearing sleeve. A method for mounting a roller includes injection molding a bearing sleeve made of plastic, inserting and/or screwing an inner part into an inner ring of a roller bearing and the bearing sleeve, and fixing the inner part to the bearing sleeve in a force-locked manner, and applying a roller to an outer ring of the roller bearing.
