Disclosed aspects relate to a structure which includes shape memory materials having transition triggers to transition the shape memory materials between initial states and transitioned states. A first physical shape of the structure exists when the first shape memory material has the first initial state and the second shape memory material has the second initial state. A second physical shape of the structure exists when the first shape memory material has the first transitioned state and the second shape memory material has the second initial state. A third physical shape of the structure exists when the first shape memory material has the first transitioned state and the second shape memory material has the second transitioned state. The physical shapes of the structure are reversible in nature. In embodiments, the shape memory materials are bonded to a flexible substrate or are clad together.

A mobile device case apparatus and method are provided that include a frame, a stand, at least one magnet, and rubber coating over the at least one magnet. The frame and stand can be 3D-printed. The frame is configured to secure a mobile device into the frame. The frame includes at least one magnet. The bottom of the stand can have a rubber coating to prevent the case from slipping when the case adheres to a metal. The stand is configured to support the weight of the apparatus and prop the mobile device up for viewing. The stand can also be configured to be a receive a mechanical element of a vehicle such as a wheelchair.

A number of magnetically assisted latch mechanisms are presented, where the latching and unlatching action is done with reduced user effort, therefore promoting speed and efficiency without sacrificing the strength of the bond of the connected components. The latching mechanisms are designed to secure panels or other similar small and large mostly flat components. The latching method is done by a rotating component that takes all the separating load once rotated into the locked position. The rotatable lock, or hammer, is also locked itself into position to prevent accidental movement by the hammer.

A screw nut includes a through hole defined by the screw nut, an internal thread that projects into the through hole, and a face that surrounds the through hole. At least three barcode patterns are disposed on the face where the at least three barcode patterns have an identical content.

A mount assembly including a rail, a mount configured to secure the rail to a surface, a laser assembly. The laser assembly includes a laser projector. The laser assembly is slidable along the rail.

A computing device and a device mount. The computing device includes a device casing having a front side and a back side and the device mount has a mount end formed with a mount face sized to fit within a recessed portion of the back side of the device casing in contact with a recessed face of the back side of the device casing. The computing device includes permanent magnets to secure the computing device to the mount face by magnetic coupling between with one or more corresponding magnets in the device mount. One of the recessed face or the mount face is formed from a thermoplastic resin and includes a plurality of raised portions. The raised portions project above the recessed face or the mount face, as the case may be, and have a thickness sufficiently small that the raised portions deform under contact between the mount face and the recessed face due to force of the magnetic coupling.

Aspects described herein include an apparatus for retaining a bag, and a related checkout system. The apparatus comprises a base portion that is positionable, by a user, at any of a plurality of positions along a surface. The base portion comprises one or more attachment members operable by the user to removably attach the base portion to the surface at a selected position of the plurality of positions. The apparatus further comprises a support portion projecting upwardly from the base portion, and one or more arms projecting outwardly from the support portion. The one or more arms are dimensioned to receive one or more handles of the bag.
