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: A camera module includes an image sensor, a lens assembly, a printed circuit board, and a substrate. The image sensor has edges that define a two-dimensional footprint substantially parallel to a surface of the image sensor. The lens assembly is coupled to a top surface of the image sensor and focuses light onto the top surface of the image sensor. Edges of the lens assembly do not extend beyond the footprint. The printed circuit board is below the image sensor and controls the image sensor. The substrate is coupled to a bottom surface of the image sensor and to a top surface of the printed circuit board. The substrate electrically couples the image sensor to the printed circuit board. Edges of the substrate do not extend beyond the footprint.

Abstract: An apparatus, system, and method for an imaging system that compensates for chromatic aberration. The imaging system may include a metalens that provides image light to a camera module. The camera module may include an optical splitter and a number of image sensors. The optical splitter separates the image light into a number of color components. The optical splitter directs the number of color components to individual image sensors. Processing logic may adjust image data for each of the color components to compensate for chromatic aberration. Processing logic may form a single chromatic aberration corrected image by recombining the adjusted image data from each of the color components.

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.
