  • Patent number: 11170480
    Abstract: The present invention is directed to systems and methods for generating virtually averaged optical coherence tomography (Oct.) images. An illustrative method can include receiving an image, identifying a first voxel of the image, and selecting a plurality of local voxels of the image. Each of the plurality of local voxels is within a defined region of the first voxel. The values of the plurality of local voxels can indicate an appearance of the local voxels in the image.

  • Patent number: 11154204
    Abstract: A system for acquiring electrocardiograph (ECG) and bioimpedance (BI) data is disclosed. The system (an ECG/BI measurement system) can use as few as one or two pairs of electrodes, permitting wearable devices employing the ECG/BI measurement system to be made into smaller, more comfortable, and more inconspicuous formats, as well as decreasing potential failure points in the measurement of electrical signals conducted between the system and the user. The system can measure both ECG and BI data using at least one shared pair of electrodes. In some cases, ECG and BI data are separately extracted from a measured signal across a shared pair of electrodes, while another pair of electrodes is being driven with a supply current. In other cases, internal switching can automatically switch a pair of electrodes between ECG-measuring circuitry and BI-measuring circuitry, such as based on a clock signal or other trigger.

  • Publication number: 20210239971
    Abstract: This document relates to an optical device that uses adaptive optics as part of an optical system. The adaptive optics can be used to correct light rays that correspond to a portion of an eye box based on information received from an eye-tracking unit, and can also correct for aberrations in the optics in the optical device. The adaptive optics include corrective elements that can be modified using modifying elements to correct the angle of light rays, such that rays associated with a specific pupil position and gaze direction of a user's eye can be made parallel and ensure a high quality image is viewed by the user.

  • Publication number: 20210228090
    Abstract: A glucose monitoring system can make use of electrocardiograph (ECG) data and bioimpedance data acquired from a wearable device. The ECG data and bioimpedance data can each be processed to obtain a glucose level. These values can be processed together to obtain an adapted glucose value. In some cases, photoplethysmography data can also be used to assist in processing of the ECG data. The various types of data can be acquired from sensors on a wearable device. The wearable device can be removably coupled to a user's skin, such as via an adhesive substrate. In some cases, the wearable device can include a reusable electronics module that couples to replaceable electrodes on a replaceable adhesive substrate.

  • Patent number: 11068052
    Abstract: A holographic display system includes an eye tracker configured to determine a position of a feature of an eye, a light source configured to output image light, and a digital dynamic hologram. The digital dynamic hologram is configured to receive the image light from the light source. The digital dynamic hologram is further configured to spatially modulate the image light based on a target image to form a reconstructed image in the eye. The reconstructed image includes noise that is non-uniformly distributed across the reconstructed image based on the position of the feature of the eye.

    Abstract: Examples are disclosed that relate to holographic near-eye display systems. One example provides a near-eye display device, comprising a diverging light source, an image producing dynamic digital hologram panel configured to receive light from the diverging light source and form an image. The near-eye display device also includes and a combiner comprising a holographic optical element positioned to receive light from the dynamic digital hologram panel and to redirect the light toward an eyebox, the holographic optical element being positioned between the eyebox and a view of an external environment to combine a view of the image formed by the dynamic digital hologram panel and the view of the external environment.

  • Patent number: 10890768
    Abstract: A polarization-based dynamic focuser for a near-eye display includes a first polarizer configured to polarize environmental light incident on the first polarizer, such that environmental light passing through the first polarizer toward a user eye has a first polarity. An image source is positioned between the user eye and the first polarizer. The image source is transparent to the environmental light and is configured to output image display light toward the user eye, at least some of the image display light having a second polarity. A dynamic lens is positioned between the user eye and the image source, and is configured to selectively focus incident light having the second polarity toward the user eye at a controllable virtual distance, where the dynamic lens does not affect incident light having the first polarity.

  • Patent number: 10881244
    Abstract: A lid assembly that can be placed on a pan having a bottom surface that is configured for placement on a burner of the stove top with one or more foods to be cooked supported above an inner bottom surface of the pan by a rack. The lid assembly covers the pan and thereby encloses the one or more foods to be cooked and the rack within a cavity defined by the pan and the lid assembly. An air flow generator mounted on a shaft that extends through a cover portion of the lid from a motor disposed on an opposite side of the cover portion rotates the shaft to produce airflow within the cavity. The lid assembly cooks foods in less time and using less energy than normally required with a conventional oven.

  • Publication number: 20200349667
    Abstract: Until the physiology of the brain and actions from the human mind are better understood, negotiations are the primary peaceful processes to resolve conflicts. Win-win resolution of conflicts often involves creativity and may not be possible. Compromise or lose-lose is a frequent alternative to win-win. However, addition of a third party interest in dyad conflicts may change the resolution of the conflict from lose-lose to (lose-lose)-win, which is a more favorable outcome. Unfortunately game theory outcome may not accurately predict long term outcome.

  • Patent number: 10809529
    Abstract: An optical device comprises a pixel array including one or more pixels. Two or more independently controllable electrodes are electrically coupled to each pixel. A common ground reference electrode is electrically coupled to all pixels of the pixel array. Each pixel includes a plurality of liquid crystal molecules. The liquid crystal molecules may be oriented in a first direction based on a first function of voltages applied by the two or more independently controllable electrodes for the pixel, and oriented in a second direction based on a second function of the voltages applied by the two or more independently controllable electrodes for the pixel. In this way, both phase modulation and polarization modulation may be introduced to light illuminating the pixel array.
