Abstract: In some embodiments, the method includes measuring a first responsive voltage value for a first voltage drop between a first terminal attached to a first suspension spring of an actuator housing a voice coil motor for moving a lens assembly and a second terminal of the magnetic coil of the voice coil motor. In some embodiments, the method includes calculating a first resistance of the magnetic coil based at least in part upon the first voltage value and measuring a second responsive voltage value for a second voltage drop between the first terminal attached and the second terminal. In some embodiments, the method includes calculating a second resistance of the magnetic coil based at least in part upon the second responsive voltage value and calculating a relative temperature for the magnetic coil based at least in part upon the first resistance and the second resistance.

Abstract: An enclosure assembly and systems and methods for using the same are disclosed. The enclosure assembly may include a base plate, a plurality of sidewalls, and one or more insulator layers disposed on the sidewalls. When coupled to a module, the enclosure assembly may least partially enclose the module to prevent the spread of EMI, to assist in heat dissipation, to protect the structural integrity of the module, and the like.

Abstract: An electronic device may include a camera module. Control circuitry within the electronic device may use an image sensor within the camera module to acquire digital images. The camera module may have lens structures that are supported by lens support structures such as a lens barrel and lens carrier. An actuator such as a voice coil motor may control the position of the lens support structures relative to internal support structures such as upper and lower spacer members. Springs may be used to couple the lens support structures to the internal support structures. Outer wall structures in the camera module such as a ferromagnetic shield structures may surround and enclose at least some of the internal support structures. The outer wall structures may have openings. The internal support structures may have pins or other alignment structures that protrude through the openings.

Abstract: A mobile device having an external housing that includes a housing camera lens cover made of graded index (GRIN) material is described herein. The housing camera lens cover has one face that faces a camera lens of a camera module included in the mobile device and another face that is exposed to the exterior of the mobile device. By using the GRIN material in the housing camera lens cover, the light rays are bent by the GRIN material before the light rays reach the camera lens. This bending of the light rays reduces the optical total track length (TTL) of the camera module and also reduces high Chief Ray Angle (CRA) such that the z-height of the camera module may be reduced while maintaining the camera's imaging performance.
