    Abstract: A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

    Abstract: An accessory device for a portable electronic device is described. The accessory device includes a front cover connected to a back cover. The front cover includes multiple segments rotatable with respect to each other. The segments include magnets that allow the segments, through magnetic coupling, to couple with another segment or with the portable electronic device. When the front cover engages the back cover, a user may remove, or pull away, a segment from the back cover, causing the remaining segments to sequentially fall away from the back cover. In some instances, when the front cover at least partially engages the back cover, one of the segments includes magnets designed to couple with magnets in the back cover, but not with magnets in another segment. The accessory device may further include an opening that receives a camera assembly of the portable electronic device and forms a mechanical interlock.

    Abstract: A wearable band may include a first strap portion including a loop, and a second strap portion positionable through the loop of the first strap portion. The second strap portion may include a multi-pole magnet assembly, the multi-pole magnet assembly including two or more magnets arranged in a multi-pole magnet structure and at least one discrete shunt positioned over a surface of the multi-pole magnet structure.

    Abstract: An efficient magnetic assembly having magnetic regions is formed by applying a magnetic field from a magnetizer to predefined portions of a monolithic substrate corresponding to the magnetized regions. In the described embodiment, the magnetic field is of sufficient strength and is applied for a sufficient amount of time to magnetize the corresponding portions of the monolithic substrate. A distance between at least two adjacent magnetized regions corresponding to a neutral zone is determined and based upon the determination, the monolithic substrate is shifted an amount less than the distance corresponding to the neutral zone and the magnetic field is re-applied to at least the shifted portion of the monolithic substrate.

    Abstract: An oblique angle polarized magnet includes a rectangular magnetized permanent magnet having a grain direction, an attraction surface, and a magnetic primary field line that is orthogonal to the grain direction but non-orthogonal to the attraction surface. The oblique angle polarized magnet may be used in a magnetically positioned apparatus, such as a tablet computing device cover operable as a stand for the tablet computing device. The magnetically positioned apparatus may be configured to assume a position where first and second magnets are oriented in a non-parallel orientation such that the first and second surfaces of the magnets oriented at an acute angle with respect to each other. The magnets may facilitate the position.
