Abstract:
Some embodiments include an image sensor and a zoom lens assembly including a plurality of movable lens elements arranged to be moved independent of one another. In some embodiments, the plurality of movable lens elements share an optical axis. Some embodiments include a lens and mirror assembly for admitting light to the miniature camera. The lens and mirror assembly includes a folded optics arrangement such that light enters the lens and mirror assembly through a first lens with an optical axis of the first lens orthogonal to the plurality of moveable lens elements. The lens and mirror assembly includes a mirror for folding the path of light from the optical axis of the first lens to the optical axis of the plurality of movable lens elements, and the lens and mirror assembly further includes an actuator for tilting the mirror.
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 camera module has an image sensor and a lens assembly that includes a lens barrel having a first cylindrical portion that includes an externally threaded portion and a second cylindrical portion that has a larger diameter than the externally threaded portion. A lens moving mechanism includes a movable sleeve having internal threads that receive the externally threaded portion of the lens assembly. The lens moving mechanism is coupled to the image sensor such that the second cylindrical portion of the lens assembly is closest to the image sensor. The camera module is assembled by inserting the lens assembly into the lens moving mechanism from the side closest to the image sensor. An installation tool may engage the second cylindrical portion to rotate the lens assembly and engage the threaded portions. Features may be provided to retain the lens assembly in the lens moving mechanism before joining the threaded portions.
Abstract:
Packages and methods of assembly are described in which barriers are utilized during overmolding to improve volumetric efficiency. In one embodiment, a barrier includes multiple variable height components located on an interior of the barrier, where the barrier prevents the variable height components from being overmolded during the encapsulation process. In one embodiment, a barrier includes a camera module mounted on an image sensor located on an interior of the barrier, where the barrier prevents the camera module and image sensor from being overmolded during the encapsulation process. In an embodiment, a barrier is mounted on a secondary tier with the secondary tier mounted on a primary tier, where the barrier prevents multiple connector components located on an interior of the barrier from being overmolded during the encapsulation process.
Abstract:
A lens assembly includes a stack of thermoplastic lenses that are aligned along a common optical axis and that are interleaved with metallic disks having an open central portion. Peripheral portions of each of the thermoplastic lenses adhere to the interleaved metallic disks to form a fused stack of lenses. A method of making the fused stack of lenses is disclosed and includes subjecting a set of interleaved lenses and metallic disks to an alternating current electromagnetic field that induces eddy currents in the metallic disks, causing heating that melts the adjacent lenses. The melted thermoplastic lens material adheres to adjacent metallic disks. The metallic disks reduce stray light from entering the lens stack, while permitting light to enter central portions of the lenses.
