Abstract: A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. A lens module in the head-mounted device may include a transparent lens element, a positioner that extends around the periphery of the transparent lens element, and an actuator that selectively shifts the positioner in a first direction. Shifting the positioner in the first direction causes the transparent lens element to be biased in a second direction that is orthogonal to the first direction at multiple points around the periphery of the transparent lens elements. The positioner may be attached to guide structures that each have a respective angled slot. Each angled slot may receive a respective tab of the transparent lens element or a respective tab of a lens shaping element that is attached to the transparent lens element.

Abstract: A lens system may include overlapping lenses that shift laterally with respect to each other to provide vision correction. The lens system may include first and second lenses that include one or more freeform surfaces and one or more non-freeform surfaces. One or more of these lens surfaces may provide adjustable presbyopic vision correction and/or a static distance vision correction.

Abstract: This disclosure relates to an integrated thermoelectric cooler and methods for forming thereof. The integrated thermoelectric cooler can include a plurality of thermoelectric rods located between the detector substrate and a system interposer. The detector substrate and the system interposer can directly contact ends of the thermoelectric rods. The integrated thermoelectric cooler can be formed by forming the plurality of thermoelectric rods on reels, for example, and the plurality of thermoelectric rods can be thinned down to a certain height. The thermoelectric rods can be transferred and bonded to the system substrate. An overmold can be formed around the plurality of thermoelectric rods. The height of the overmold and thermoelectric rods can be thinned down to another height. The thermoelectric rods can be bonded to the detector substrate. In some examples, the overmold can be removed.
