Abstract: A Magnetoresistive Tunnel Junction (MTJ) device includes an elongated MTJ structure formed onto a substrate, the MTJ structure including a magnetic reference layer and a tunnel barrier layer. The MTJ device also includes a number of discrete free magnetic regions disposed onto the tunnel barrier layer. The ratio of length to width of the elongated MTJ structure is such that the magnetic field of the magnetic reference layer is pinned in a single direction.

Abstract: A bracelet including a housing for supporting a removable plaque is disclosed. The housing is preferably connected at a first end and a second end to a strap. The housing may further include a base, and a pair of sidewalls which support the removable plaque in the engaged or secured position. The base may further support an element of an engagement member which secures the removable plaque to the base. In one embodiment, the engagement member includes a pair of magnets supported on an inner surface of the base and plaque, respectively, which are magnetically attracted to each other. The removable plaque preferably includes an inner surface which supports the magnet and an outer surface for receiving ornamentation, such as indicia thereon. The plaque may further include a pair of side walls which overlap the side walls of the housing in the engaged position.

Abstract: A kit for making a three-dimensional picture includes a frame encircling a three-dimensional window into which may be inserted a plurality of substantially planar decorated scenes. The depth of a scene in the window in determined by bending backward resilient hinges carried at the edges of the scene. The scenes are removably anchored in the window by frictional engagement between the hinges and the inner sides of the frame. Cut out regions in the scenes permit more remote scenes to be viewed, creating a three-dimensional effect. Including replicas of scenes allows more than one picture to be created with the kit.
