Abstract: Sensor assemblies for electronic devices are described. According to some embodiments, the sensor assemblies include solid-state sensors, such as capacitive sensors, piezoelectric sensors or piezoresistive sensors. The sensor assemblies can include a number of features that provide a compact profile, making them well suited for integration into small spaces of electronic device enclosures. The sensor assemblies can also include features that isolate movement of various parts of the sensor assemblies, allowing for accurate detection of a sensing event.

Abstract: An electronic device has an electrically adjustable shutter. The shutter may be placed in a transparent state or a nontransparent state. The shutter may overlap a portion of a display, may overlap a liquid contact indictor or a structure with text in a device, or may overlap an optical component such as an optical proximity sensor, ambient light sensor, visible light-emitting diode or laser, infrared light-emitting diode or laser, visible light image sensor, or infrared light image sensor. Control circuitry in the electronic device may place the shutter in an opaque state to hide an overlapped component from view or may place the shutter in a transparent state to allow the overlapped component to transmit or receive light. The adjustable shutter may exhibit changes in its transmission spectrum in different modes of operation and may be used as a camera filter or neutral density filter.

In one embodiment, a number of insert molded retaining members are utilized to inhibit outward deformation of a sidewall of the housing during a drop event. In another embodiment, a cowling is utilized to retain a number of board-to-board connectors within communication slots on a printed circuit board (PCB). In another embodiment, a C-shaped washer having diametrically opposed protrusions is utilized to adjust an alignment of an internal component.

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: Electronic devices having input structures that are operative to translate a relatively small travel of an input surface to a larger travel elsewhere. For example, force exerted on an input surface of an input body may cause a corresponding input body to move a first distance. An arm, lever mechanism, or the like may have an end or other portion that moves a second distance in response to the input body's motion. The second distance may be greater than the first; in some embodiments, the second distance may be an order of magnitude or more than the first distance. The travel may close or open a switch in response to the force exerted on the input surface.
