An input device assembly with a support pad is provided. The input device assembly includes the support pad and an input device. The support pad includes a first main body and a first magnetic attraction element. The first main body has a first bottom surface and a first curvy surface. The input device includes a second main body and at least one second magnetic attraction element. The second main body has a second bottom surface and a second curvy surface. The first curvy surface of the support pad is contactable with one of plural portions of the second curvy surface of the input device. The first magnetic attraction element and one of the at least one second magnetic attraction element are magnetically attracted by each other. Consequently, the support pad is in close contact with the input device.

A mobile device mounting system includes a device case and a mount. The device case includes: an insert including a rectangular bore and defining a set of undercut sections about the rectangular bore; and a first set of magnetic elements arranged in a first pattern about the rectangular bore. The mount includes: a body; a polygonal boss extending from the body and configured to insert into the rectangular bore; a set of locking jaws arranged on the polygonal boss configured to transiently mate with the set of undercut sections to constrain the polygonal boss within the rectangular bore; and a second set of magnetic elements arranged in a second pattern about the polygonal boss and configured to transiently couple to the first set of magnetic elements to transiently retain the mount against the device case and to drive the set of locking jaws toward the set of undercut sections.

An optical transceiver includes an outer part provided outside the apparatus upon an engagement of the optical transceiver with the apparatus. The outer part includes a first spindle, a rotational member, a sliding member. The rotational member is configured to rotate on the first spindle. The sliding member is configured to move along the first direction. The rotational member has a hole. The sliding member has a second spindle. The first spindle and the second spindle are fit with the hole. The optical transceiver includes an inner part provided inside the apparatus upon the engagement with the apparatus. The hole has a first circular area, a second circular area, and a straight area. The first spindle is fit with the first circular area. The second spindle is fit with the second circular area. The straight area is connected between the first circular area and the second circular area.

Disclosed is a ratcheting retainer for securing one or more objects, such as wire bundles, to a component. The ratcheting retainer includes a ratchet strap assembly, a fastener, and retainer clip. The ratchet strap assembly, which can adjust in diameter, circumscribes and secures a first object. The fastener is coupled to the ratchet strap assembly and secures the ratcheting retainer to the component. The retainer clip is coupled to the ratchet strap assembly and secures a second object to the ratchet strap assembly

Embodiments of the present disclosure disclose a mounting bracket and a self-propelled robot. The mounting bracket includes a housing, a rotating shaft and a magnetic positioning assembly. The housing is provided with an inner cavity. The rotating shaft is configured to rotate about an axis in the inner cavity. The magnetic positioning assembly includes a first magnetic element and a second magnetic element which are respectively arranged on the housing and the rotating shaft. The laser distance sensor is attached to the rotating shaft and configured to rotate about the axis. The mounting bracket is configured to prevent the rotating shaft from deviating from the axis by generating a force between the first magnetic element and the second magnetic element in a radial direction of the rotating shaft.

A cable routing fastener includes a body and an arm extending therefrom, a head projecting from the body, a cover adjacent the arm so movement of the cover is temporarily restricted by the arm, and a cable connector. The body inserts into an aperture in a panel and positions the head and the cable connector adjacent the panel. The head includes an indicia element indicating an assembly status of the fastener, i.e., whether it is properly installed or not. The cover conceals the indicia element in a concealed mode, and moves relative to the head to an exposed mode so the indicia element is exposed for reading. The arm moves when the body is inserted so the arm no longer interferes with movement of the cover, so the cover can be moved by a user, transitioning from the concealed mode to the exposed mode. A related method of use is provided.
