Publication number: 20240035931Abstract: A plurality of modules housed in a chassis is secured to the railroad tie to capture high resolution images of the underside of a train car as it passes over the plurality of cameras. These images are important to insure the structural integrity of the parts of the rail car as well as the connection means—a coupler and pin—between two rail cars. The cameras are configured to capture at a predetermined rate or to operate in sync with the velocity of the train as measured by the Linear Speed Sensor. As the images are taken, the images can be downloaded and sent to a remote location for further analysis.Type: ApplicationFiled: August 1, 2022Publication date: February 1, 2024Inventor: Jeremy Grata

Publication number: 20220377251Abstract: A plurality of cameras is secured to railroad ties to take high resolution images of the underside of a train car as it passes over this plurality of cameras. These images are important to insure the structural integrity of the parts of the rail car as well as the connection means—a coupler and pin—between two rail cars. The shutter speed of the cameras is determined by the speed of the train as it passes over the cameras. As the images are taken, the images can be downloaded and sent to a remote location for further analysis.Type: ApplicationFiled: May 21, 2021Publication date: November 24, 2022Inventors: Jeremy Grata, Edward Buschelman, Julie Lee

Patent number: 11503275Abstract: An improved method, system, and apparatus is provided to perform camera calibration, where cameras are mounted onto a moving conveyance apparatus to capture images of a multi-planar calibration target. The calibration process is optimized by reducing the number of images captured while simultaneously preserving overall information density.Type: GrantFiled: December 19, 2019Date of Patent: November 15, 2022Assignee: Magic Leap, Inc.Inventors: Jeffrey Steven Kranski, Frederick Dennis Zyda, Grace Vesom, Grace Shin-Yee Tsai, Jeremy A. Grata, Zhiheng Jia, Li Jiang

Patent number: 11445170Abstract: Embodiments provide a camera design (e.g., an eyeball camera) that mimics a human eye in geometry, optical performance and/or motion. The eyeball camera adopts the same cornea and pupil geometry from the human eye, and has the iris and pupil configured with multiple texture, color or diameter options. The resolution of the eyeball camera is designed to match the acuity of typical 20/20 human vision, and focus is adjusted from 0 to 4 diopters. A pair of eyeball cameras are mounted independently on two hexapods to simulate the human eye gaze and vergence. The perceived virtual and real world are calibrated and evaluated based on eye conditions like pupil location and gaze using the eyeball cameras. The eyeball camera serves as a bridge to combine the data from spatial computing like eye tracking, 3D geometry of the digital world, display color accuracy/uniformity, and display optical quality (sharpness, contrast, etc.).Type: GrantFiled: July 10, 2020Date of Patent: September 13, 2022Assignee: Magic Leap, Inc.Inventors: Zhiheng Jia, Jeffrey Todd Daiker, Timothy Alan Ellis, Xiao Li, Jeremy A.

Patent number: 11381804Abstract: An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.Type: GrantFiled: July 2, 2020Date of Patent: July 5, 2022Assignee: Magic Leap, Inc.Inventors: William Hudson Welch, Jeremy A. Grata, Marwan Hussein

Patent number: 11300925Abstract: A system for generating multi-depth image sequence comprising a modulation array. The modulation array comprising a plurality of light modulators which may shift light incident upon the modulators by a number of degrees. The plurality of light modulators may shift light in concert according to a modulation shift pattern. The modulation shift pattern can be configured to focus incident light to a voxel or to form a 3-D image. One or more modulation shift patterns can be changed or cycled through to raster one or more image objects in one or more image depth planes.Type: GrantFiled: November 17, 2020Date of Patent: April 12, 2022Assignee: Magic Leap, Inc.Inventors: Jeremy A.
