摘要： 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.

摘要： A size of an optical aperture for an imaging system is adjustable. The size of the optical aperture can be adjusted based on refractive index matching, optical absorption, or near field coupling techniques. These techniques may also be used to provide a high speed optical shutter.

摘要： 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.
