Abstract: A method for coating an optical substrate with an anti-reflection multilayered stack is provided. The method includes depositing a stack of dielectric layers having alternate index of refraction over a substrate, to form an anti-reflective coating. The method also includes depositing a first layer of low refractive index material on top of the stack of dielectric layers, etching the first layer of low refractive index material with a solvent at a selected temperature, and conformally depositing a sealant material over the first layer of low refractive index material to complete the anti-reflective coating. A headset for virtual reality, augmented reality, or mixed reality applications including optical components having an anti-reflection coating fabricated per the above method is also provided.

Abstract: Various embodiments set forth computer vision systems. In some embodiments, one or more activation maps are generated based on eye gaze data and used to control operation of one or more sensors. Each activation map indicates a highest density for acquiring sensor data in a region corresponding to an eye gaze direction and lower densities for acquiring sensor data in other regions. After the sensor data is acquired, a processing pipeline sub-samples (or bins) and processes regions of the acquired sensor data at different ratios based on the eye gaze direction. The sub-sampled (or binned) data for each region is processed independently, and results of the processing are combined to generate processed data, such as an image that can be displayed to a user.

Abstract: Disclosed herein are related to a first device to communicate with an access point and a second device. In one aspect, the first device communicates with the access point during the first time interval through a first wireless communication. In one aspect, the first device prevents communication with the access point during the second time interval. In one aspect, the first device communicates, as a soft access point, with a second device during the third time interval within the second time interval through a second wireless communication, the third time interval shorter than the second time interval.

Abstract: An augmented reality headset is provided that includes a first microphone mounted on a headset and configured to receive a first audio signal from a speaker, and a second microphone remotely located from the headset and configured to receive a second audio signal from the speaker. The augmented reality headset also includes a memory storing multiple instructions, and one or more processors configured to execute the instructions. When the one or more processors execute the instructions, they cause the augmented reality headset to: synchronize the first audio signal and the second audio signal, form an enhanced audio signal with the first audio signal and the second audio signal, and provide the enhanced audio signal to a user of the augmented reality headset.

Abstract: A system for three-dimensional object sensing using fringe-projection profilometry with Fourier transform analysis is described. A fringe-projection profilometry (FPP) projector simultaneously transmits a frequency signal pattern (i.e., modulated or AC signal) and a zero-frequency signal pattern (i.e., unmodulated or DC signal) onto an object's surface. Alternatively, the projector projects two frequency signal patterns phase-shifted by 180 degrees. A dual readout sensor captures reflections of both signals from the object's surface as adjacent frames, and the DC signal is extracted by subtraction of addition to obtain an enhanced signal. The enhanced signal is used to generate a wrapped phase map through Fourier transform profilometry (FTP). The resulting wrapped phase map is unwrapped, and three-dimensional reconstruction of the object's surface is generated by converting phase from the unwrapped phase map to three-dimensional coordinates.
