Abstract:
An enclosure and a method for forming an enclosure are disclosed. The enclosure may be formed from metal, such as aluminum, and further include a non-metal portion allowing for transmission and receipt of electromagnetic waves. The non-metal portion may be interlocked to the enclosure and in particular, to a region within the enclosure including a first material having a relatively high strength and stiffness compared to the non-metal portion. Interlocking means may include forming dovetail cuts into the enclosure to receive the non-metal portion, a hole or cavity drilled into the enclosure which includes internal threads, and a rod inserted into the first material to provide a tension to the non-metal portion. Methods of assembling internal components using anodization are also disclosed.
Abstract:
Antenna related features of a mobile phone or computing device are disclosed. In one embodiment, wireless control and signal are fed separately through difference types of flexes to optimize performance and cost. In one embodiment, active switching and processing of differing conductive trace lengths are performed on an antenna flex so that antenna performance can be optimized for multiple wireless technologies covering a wide range of wavelengths. In one embodiment, a cantilever arm affixed to a ground screw can provide double grounding in a region with no available screw points due to high z constraint. In one embodiment, a device can provide double feed for antenna through a single screw. In one embodiment, a short pin can be configured to support thinner metal. In one embodiment, a “vibrator bracket/LDS short pin” structure can be used to share a common screw point.
Abstract:
An apparatus comprises a fingerprint sensor having a set of capacitive elements configured for capacitively coupling to a user fingerprint. The fingerprint sensor may be disposed under a control button or display element of an electronic device, for example one or more of a control button and a display component. A responsive element is responsive to proximity of the user fingerprint, for example one or both of a first circuit responsive to motion of the control button, and a second circuit responsive to a coupling between the fingerprint and a surface of the display element. The fingerprint sensor is disposed closer to the fingerprint than the responsive element. The control button or display component may include an anisotropic dielectric material, for example sapphire.
Abstract:
A stretch release adhesive is disclosed. The stretch release adhesive can be used for extracting an electrical component from an interior surface of a housing of a mobile computing device. The stretch release adhesive can have a double-sided adhesive body configured to adhere the component to the interior surface of the housing. A portion of the double-sided adhesive body is configured to extend out from between the electrical component and the interior surface of the housing to provide a graspable portion. When the stretch release adhesive is adhered between the electrical component and the internal surface of the housing, the stretch release adhesive can receive a pulling force at the graspable portion. If pulled with enough force, the stretch release adhesive will extend outwardly from between the electrical component and the internal surface of the mobile computing device, then completely release the electrical component from the mobile computing device.
Abstract:
Electronic devices may be provided that contain flexible displays that are bent to form displays on multiple surfaces of the devices. Bent flexible displays may be bent to form front side displays and edge displays. Edge displays may be separated from front side displays or from other edge displays using patterned housing members, printed or painted masks, or by selectively activating and inactivating display pixels associated with the flexible display. Edge displays may alternately function as virtual buttons, virtual switches, or informational displays that are supplemental to front side displays. Virtual buttons may include transparent button members, lenses, haptic feedback components, audio feedback components, or other components for providing feedback to a user when virtual buttons are activated.
Abstract:
Electronic devices may be provided that have antenna traces. The antenna traces may be configured to form an inductive loop that serves as a near field communications antenna. A layer of ferrite may be provided to reduce interference between the antenna and internal device components. The layer of ferrite and the antenna traces may be deposited on a common substrate such as a layer of polymer or a dielectric electronic device housing. A protective layer of polymer may be used to form a coating on the layer of ferrite. Ferrite may be formed on the same side of a substrate as the antenna traces or may be formed on an opposing side of the substrate.
Abstract:
An electronic device may include a biometric sensing device that has a sensing area, and a substrate positioned above the sensing area and/or the biometric sensing device. The substrate can include vias that are formed through at least a portion of the substrate. The vias can be positioned at least above the sensing area of the biometric sensing device. The vias may be filled with a conductive material or a dielectric material. Alternatively, some vias can be filled with a conductive material while other vias are filled with a non-conductive or dielectric material.

Abstract:
Systems and methods for forming button assemblies for electronic devices are disclosed. According to some embodiments, the button assemblies include one or more sound improvement features to improve the sound that the button assemblies make when pressed by users of the electronic devices. According to some embodiments, the button assemblies include shims that provide proper alignment of the various components of the button assemblies and to accommodate any tolerance stack up of the various components of the button assemblies. The shims can include alignment features to prevent the shims from shifting within the button assemblies. According to some embodiments, thicknesses of the shims are customized to accommodate varying tolerance stack ups of the components of the button assemblies. In some embodiments, the button assemblies include a combination of sound improvement features and shims.
Abstract:
An electronic device may include a display. The display may be an organic light-emitting diode display. The organic light-emitting diode display may have a substrate layer, a layer of organic light-emitting diode structures, and a layer of sealant. Vias may be formed in the substrate layer by laser drilling. The vias may be filled with metal using electroplating or other metal deposition techniques. The vias may be connected to contacts on the rear surface of the display. Components such as flexible printed circuits, integrated circuits, connectors, and other circuitry may be mounted to the contacts on the rear surface of the display.
