    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.

    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 article having a multiple magnetic polarities and a method for making the article are disclosed. The article can be a monolithic substrate form from a metallic material or materials. The article may include a first magnetic polarity and a second magnetic polarity opposite the first magnetic polarity. Methods for making the article include provide either providing a monolithic substrate having a first magnetic polarity, or applying a first magnetic field to the monolithic substrate to impart a first magnetic polarity. The method may also include raising the temperature of the monolithic substrate in order to reduce the coercivity of the monolithic substrate. The temperature of the monolithic substrate may also be selectively raised to lower the coercivity of the monolithic substrate in associated areas. By lowering the coercivity, the second magnetic polarity may be imparted on the monolithic substrate.

    Abstract: An electronic device may have a conductive housing with an antenna window. Antenna structures may be mounted adjacent to the antenna window. The antenna structures may have a dielectric carrier. Patterned metal antenna traces may be formed on the surface of the dielectric carrier. A proximity sensor may be formed from a flexible printed circuit mounted on the dielectric carrier. The flexible printed circuit may have a tail that contains a transmission line for feeding the antenna structures. The transmission line may include a positive signal conductor that is maintained at a desired distance from the conductive housing using a polymer sheet. A portion of the antenna structures may protrude between a microphone and a camera module. Plastic camera module housing structures may have an inner surface coated with a shielding metal. A U-shaped conductive fabric layer may be used as a grounding structure.
