    Abstract: A balanced magnetic string and methods for forming same are described. The balanced magnetic string includes at least a plurality of magnetic elements linearly arranged in an alternating magnetic polarity pattern and each comprising a first magnetic volume and a compensating magnetic element having a second magnetic volume that is different than the first magnetic volume. The plurality of magnetic elements and the compensating magnetic element magnetically interact to provide a resultant magnetic field having a desired magnetic field strength at a point of interest.

    Abstract: This application relates to a case for retaining a portable electronic device and an accessory. The case can include a main body that includes a back panel and sidewalls for retaining a portable electronic device. The case can also include a receptacle coupled to the main body. The receptacle can have a cavity that generally corresponds to the dimension of an accessory for retaining the accessory. The case can further include a first terminal, a second terminal, and a battery. The first terminal can receive electrical energy from the portable electronic device to charge the battery. And the electrical energy stored in the battery can be transferred to the accessory through the second terminal. The case and the portable electronic device may communicate via near-field communication. The case can further include a slotted compartment to store money and credit cards.

    Abstract: An accessory device for use with an electronic device is disclosed. The accessory device may include multiple layers. One layer may be formed from a plastic. Other layers may include a fabric layer and a silicone layer. The accessory device may further include a retaining feature designed to hold or carry an object, such as a stylus for use with the electronic device. The accessory device may include a recessed region suited to receive the retaining feature. This allows the retaining feature to be stored in the accessory device when the retaining feature is not in use. Further, the retaining feature may be co-planar with an interior region of the accessory device such that the electronic device is not disturbed when positioned in the accessory device. In this manner, the retaining feature may be hidden. Also, the retaining feature may be deployed from the recessed region and receive the object.

    Abstract: An integrated system of sensors that can be used to detect a direction of an externally applied magnetic field is disclosed. In one embodiment, the system can be incorporated into a compact package that can be used within an electronic device. A processor can use signals provided by the sensor system to provide an indication of the direction of the externally applied magnetic field. In one embodiment, the sensors can take the form of analog sensors such as Hall Effect sensors configured in such a way that the direction of the externally applied magnetic field can be deduced based in part upon detection signals provided by the Hall Effect sensors. In one embodiment, the Hall Effect sensors can be stacked one atop the other in such a way that relative signal strength of the detection signals from the sensors can indicate the direction of the externally applied magnetic field.

    Abstract: An accessory device for use with an electronic device is disclosed. The accessory device may include a cover configured to overlay an electronic device (or device) or fold to form a support structure for the electronic device. The cover may include an attachment feature that electrically couples with the device, and a keyboard foldable with respect to the cover. Further, the keyboard may include a retention feature designed to receive the attachment feature in a folded configuration of the cover. The accessory device may further include an electrically conductive fabric that folds with the cover. The accessory device may include an array of magnets throughout the attachment feature, the cover, and the keyboard. The magnets may be used to magnetically couple together 1) segments of the cover, 2) the cover and the keyboard assembly, 3) and/or the device with the cover.
