Abstract: A lens with an adjustable surface profile can include an actuatable layer, an optical layer, and at least one actuator. The optical layer can include a deformable polymer, and the actuatable layer can have a surface profile that is configured to be adjustable using the at least one actuator. The optical layer, meanwhile, can be configured to deform when the at least one actuator actuates the actuatable layer.

Abstract: Embodiments of the present disclosure relate to power saving mechanisms for a wearable camera device. The camera device comprises an image sensor and lens assembly in an optical series with the image sensor. At a first orientation of the camera device, an offset is between a center axis of the image sensor and an optical axis of the lens assembly. At a second orientation of the camera device, at least one of the image sensor and the lens assembly sag due to gravity such that the center axis and the optical axis substantially overlap while the camera device is in a neutral state. The lens assembly and the image sensor can further allow a dynamic amount of sag relative to each other.

Abstract: An augmented reality apparatus includes a plurality of transmission lines, plural signal-generating circuits, at least one additional transmission line, at least one signal-processing circuit, a multiplexer having a plurality of inputs and at least one output, a plurality of matching networks, and an additional matching network coupling the additional transmission line to the output of the multiplexer. Example AR/VR devices include a camera configured to receive light from the external environment of the device and to provide a camera signal. The camera may include a surface variable lens including a support layer, an optical layer, a membrane layer, and an actuator. A computer-implemented method for anatomical electromyography test design includes identifying a wearable device having a frame including a plurality of electrodes, and calibrating the plurality of electrodes. In augmented reality and virtual reality systems, DNN accelerators may be based on various technologies to improve computing speed and energy efficiency.

Abstract: Embodiments of the present disclosure relate to a camera device with optical image stabilization (OIS) having a range of motion that is asymmetric along two spatial dimensions. The camera device includes an image sensor, a lens assembly in an optical series with the image sensor, and an OIS assembly. The OIS assembly initiates a first motion of at least one of the image sensor and the lens assembly along a first direction parallel to a first axis, the first motion having a first range. The OIS assembly further initiates a second motion of at least one of the image sensor and the lens assembly along a second direction parallel to a second axis orthogonal to the first axis, the second motion having a second range different than the first range.

Abstract: An adjustment image of a projected image is captured by a disparity image sensor. A first defocus factor in generated response to comparing the adjustment image with a reference image driven onto a display projector assembly the generated the projected image. A second defocus factor is generated in response to an alignment of a first intensity profile of the adjustment image and a second intensity profile of the adjustment image. A focusing lens of the display projector assembly is adjusted in response to at least one of the first defocus factor and the second defocus factor.

Abstract: Embodiments of the present disclosure further relate to a camera device assembled such that to reduce (and in some cases minimize) auto-focusing actuation power when the camera device operates in a macro mode. The camera device includes an image sensor and a lens assembly in an optical series with the image sensor. During manufacturing of the camera device, the lens assembly is assembled within the camera device to have an optical axis substantially parallel to gravity and positioned to have an offset along the optical axis. The offset is determined during manufacturing of the camera device such that, when the camera device is in the macro mode, the lens assembly is positioned at a neutral position relative to the image sensor without actuation applied to the lens assembly.
