Patent number: 10506165Abstract: A concussion screening device includes an illumination unit, an image sensor array, a processing unit, and system memory. The concussion screening device displays stimuli on the illumination unit and receives a plurality of images on the image sensor array. The stimuli correspond to a concussion test. The processor processes the plurality of images, which includes detecting one or more pupils of an evaluated person during the concussion test. Based on the processing, the concussion screening device determines whether or not an evaluated person has suffered a concussion. The results are displayed to a user and/or the evaluated person.Type: GrantFiled: October 29, 2015Date of Patent: December 10, 2019Assignee: WELCH ALLYN, INC.Inventor: John A. Lane

Patent number: 10496162Abstract: The systems and methods described herein assist persons with the use of computers based on eye gaze, and allow such persons to control such computing systems using various eye trackers. The systems and methods described herein use eye trackers to control cursor (or some other indicator) positioning on an operating system using the gaze location reported by the eye tracker. The systems and methods described herein utilize an interaction model that allows control of a computer using eye gaze and dwell. The data from eye trackers provides a gaze location on the screen. The systems and methods described herein control a graphical user interface that is part of an operating system relative to cursor positioning and associated actions such as Left-Click, Right-Click, Double-Click, and the like. The interaction model presents appropriate user interfaces to navigate the user through applications on the computing system.Type: GrantFiled: July 26, 2017Date of Patent: December 3, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Harish Sripad Kulkarni, Dwayne Lamb, Ann M Paradiso, Eric N Badger, Jonathan Thomas Campbell, Peter John Ansell, Jacob Daniel Cohen

Patent number: 10481402Abstract: In certain embodiments, enhancement of a field of view of a user may be facilitated via one or more dynamic display portions. In some embodiments, one or more changes related to one or more eyes of a user may be monitored. Based on the monitoring, one or more positions of one or more transparent display portions of wearable device may be adjusted, where the transparent display portions enable the user to see through the wearable device. A live video stream representing an environment of the user may be obtained via the wearable device. A modified video stream derived from the live video stream may be displayed on one or more other display portions of the wearable device.Type: GrantFiled: May 31, 2019Date of Patent: November 19, 2019Assignee: University of MiamiInventors: Mohamed Abou Shousha, Ahmed Sayed

Patent number: 10480926Abstract: A fiber housing includes multiple shape sensing cores and a single optical core. A distal end of the fiber housing is positionable to direct the single optical core to a current point of an anatomical target. Collimated light over a first range of frequencies is projected from the single optical core to the current point. OFDR is used to detect reflected light scattered from the current point and to process the detected light to determine a distance to the current point. Light over a second range of frequencies is projected through the multiple shape sensing optical cores to the distal end of the fiber housing. OFDR is used to measure light reflected from the distal end of the fiber housing back through the multiple shape sensing optical cores and to process the measurement to determine a position in three dimensional space of the distal end of the fiber housing and a pointing direction of the distal end of the fiber housing.Type: GrantFiled: December 8, 2016Date of Patent: November 19, 2019Assignee: Intuitive Surgical Operations, Inc.Inventors: Mark E. Froggatt, Eric E. Sanborn, Federico Barbagli

Patent number: 10466478Abstract: Examples of an imaging system for use with a head mounted display (HMD) are disclosed. The imaging system can include a forward-facing imaging camera and a surface of a display of the HMD can include an off-axis diffractive optical element (DOE) or hot mirror configured to reflect light to the imaging camera. The DOE or hot mirror can be segmented. The imaging system can be used for eye tracking, biometric identification, multiscopic reconstruction of the three-dimensional shape of the eye, etc.Type: GrantFiled: September 21, 2016Date of Patent: November 5, 2019Assignee: Magic Leap, Inc.Inventors: Michael Anthony Klug, Adrian Kaehler

Patent number: 10469823Abstract: An image processing device of an image apparatus includes a distance image generation unit that generates a first distance image and a second distance image from the output signals of a first camera and a second camera based on flight times of light. The image processing device includes a stereo image generation unit that generates a stereo image from the output signals of the cameras. The image processing device includes an image comparison unit that compares the stereo image and the distance image and detects an abnormality of at least one of the first distance image and the second distance image.Type: GrantFiled: April 5, 2018Date of Patent: November 5, 2019Assignee: FANUC CORPORATIONInventors: Yuuki Takahashi, Atsushi Watanabe, Minoru Nakamura

Patent number: 10466781Abstract: According to one embodiment, an eye movement detecting device comprises first, second, third, fourth and fifth electrodes. A line connecting the first and the third electrodes passes through the right eye and a line connecting the second and the fourth electrodes passes through the left eye on at least one of a front view, a plan view or a side view. A distance between the fifth and the first electrodes is equal to a distance between the fifth and the second electrodes. A distance between the fifth and the third electrodes is equal to a distance between the fifth and the fourth electrodes. The detector respectively detects a horizontal movement of the right eye and a horizontal movement of the left eye.Type: GrantFiled: June 11, 2018Date of Patent: November 5, 2019Assignee: KABUSHIKI KAISHA TOSHIBAInventor: Hiroaki Komaki
