Abstract:
A portable computing device is disclosed. The portable computing device can take many forms such as a laptop computer, a tablet computer, and no on. The portable computing device can include a single piece housing formed from a radio opaque material with a cover formed from a radio transparent material. To implement a wireless interface, an antenna stack-up can be provided that allows an antenna to be mounted to a bottom of the cover. Methods and apparatus are provided for improving wireless performance. For instance, in one embodiment, a metal housing can be thinned to improve antenna performance. As another example, a faraday cage can be formed around speaker drivers to improve antenna performance.
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:
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 input device, such as a keyboard, includes one or more keys that each includes a keycap operable to move within an aperture of a frame to activate a switch and fabric disposed over the frame and keycap. A first region of the fabric is bonded to the keycap and a second region of the fabric is bonded to the frame. The first region may be an embossed region and the second region may be an unembossed region. The fabric may dampen sound from within the keyboard, such as noise related to movement of the keycap, activation of the switch, and so on. The fabric may also form a barrier that restricts passage of contaminants into the aperture and/or other portions of the input device.
Abstract:
A portable input device is described. The portable input device can wirelessly send control signals to an external circuit. The control signals can derive from touch or gestures applied to a touch sensitive surface. The control signals can also include a mouse click equivalent control signal generated by mechanical manipulation of the portable input device.
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.
Abstract:
Slide input component assemblies of an electronic device and methods for making the same are provided. In some embodiments, a slide input component assembly may include a slide button subassembly that may have a knob, a base, a retention mechanism that may couple the knob to the base, and a shell part that may be provided about at least a portion of the base. The slide input component assembly may also include a slide switch subassembly that may have a switch that may be configured to move along a switch path when the slide button subassembly moves along a button path.

Abstract:
An earbud tip for an in-ear headphone can include an outer body; an inner tube extending at least partially within the outer body, the tube having opposing first and second ends and first and second openings at the opposing first and second ends, respectively, the first opening configured to emit audio signals provided by a speaker of an in-ear headphone into a user's ear canal during operation of the in-ear headphone and when the earbud tip seals the user's ear canal and the second opening configured to be removably coupled to a portion of the in-ear headphone; and one or more channels extending from an outer periphery of the earbud tip to the inner tube.
Abstract:
This application relates to devices that utilize magnets and associated magnetic sensors. A magnetic sensor can be positioned and oriented with respect to a magnetic element such that the magnetic sensor is capable of detecting a horizontal magnetic field component in contrast to the conventional paradigm of detecting a vertical magnetic field component. This can be accomplished by orienting a magnetically sensitive surface of the magnetic sensor about ninety degrees with respect to a magnetic vector of the magnetic element.
