  • Patent number: 11051691
    Abstract: A process for ocular analysis is disclosed. Aspects of the process display, on a device having a display and a camera sensor, a regimented pattern as a stimulus. The camera sensor captures video of an environment. The process also involves isolating an iris within the environment as a bounded region of the captured video. Facial landmarks are assigned to the iris within the bounded region. Thereafter, raw movement data of the facial landmark in response to the regimented pattern is extracted from the captured video. The raw movement data is used to create filtered movement data (e.g., data that has been checked for errors). The process also compares the filtered movement data to a predetermined movement response that is based on the regimented pattern. From the comparison, a performance score is generated. The performance score is used to generate an output.

  • Patent number: 10757328
    Abstract: Disclosed are an apparatus and a method of low-latency, low-power eye tracking. In some embodiments, the eye tracking method operates a first sensor having a first level of power consumption that tracks positions of an eye of a user. In response to detection that the eye does not change position for a time period, the method stops operation of the first sensor and instead operates a second sensor that detects a change of position of the eye. The second sensor has a level of power consumption lower than the level of power consumption of the first sensor. Once the eye position changes, the second sensor resumes operation.

  • Patent number: 10716469
    Abstract: A system or method for measuring human ocular performance can be implemented using an eye sensor, a head orientation sensor, and an electronic circuit. The device is configured for measuring vestibulo-ocular reflex, pupillometry, saccades, visual pursuit tracking, vergence, eyelid closure, dynamic visual acuity, retinal image stability, foveal fixation stability, focused position of the eyes or visual fixation of the eyes at any given moment and nystagmus. The eye sensor comprises a video camera that senses vertical movement and horizontal movement of at least one eye. The head orientation sensor senses pitch and yaw in the range of frequencies between 0.01 Hertz and 15 Hertz. The system is implemented as part of an impact reduction helmet that comprises an inner frame having interior pads configured to rest against a person's head and one or more shock absorption elements attached between the inner frame and the spherical shell that couple the spherical shell to the inner frame.

  • Patent number: 10674904
    Abstract: The system allows one with no prior training in refraction to subjectively screen, measure, and correct for their own refractive error without the assistance of a second person through subjective self-refraction (SSR). One accomplishes SSR by interacting with refractor input controls, which manipulate lenses in front of their eye(s). The SSR process is accomplished via pre-programming, allowing for direct feedback between the system and user from sensory cues that are prompted by interacting with the input controls. The resulting health data may be displayed or transmitted to the user or another individual for later use. The refraction process may incorporate remote data management technology and computer network capabilities that provides for efficiency, improved accuracy, cost savings and user experience enhancement and may allow for greater access to vision correction services for many people.

  • Patent number: 10667949
    Abstract: A laser eye surgery system includes a computer which scans a focused laser beam in a trajectory over a reticle or target and determines beam quality via laser light reflected from the target. The target may have a grid pattern of lines, with the diameter of the focused laser beam determined based on a time interval for the scanned beam to move onto a line of the grid pattern. Methods for measuring beam quality in a laser eye surgery system provide a direct, quantitative quality measurement of the focused laser beam, and may be performed quickly and automatically. Using scanning mirror position information together with signals resulting from laser light reflected from the target, the laser eye surgery system may also be calibrated.
