The data generation computer system includes: at least one processor, and memory storing computer instructions. The data generation system is, upon execution of the computer instructions by the at least one processor. The method includes: obtaining background sensor data from sensor data of a sensor; augmenting the sensor background data with one or more objects to generate an augmented background sensor output, wherein the augmenting the background sensor data includes determining a two-dimensional (2D) representation of each of the one or more objects based on a pose of the sensor; and generating sensor-realistic augmented sensor data based on the augmented background sensor output through use of a domain transfer network that takes, as input, the augmented background sensor output and generates, as output, the sensor-realistic augmented sensor data.Type: ApplicationFiled: May 22, 2024Publication date: November 28, 2024Inventors: Henry X.

Patent number: 10973391Abstract: A system for virtual reality/mixed reality viewing of a surgical procedure includes an endoscope having an elongated flexible or rigid main body with a proximal end and a distal end. A spherical element is coupled to the distal end. A plurality of wide field-of-view cameras or optical collections lenses are aligned about the spherical element to provide 360 degree omnidirectional stereoscopic visualization. A fiber optic illumination strip is positioned around the periphery of the spherical element adjacent each camera. A central processing unit is in communication with the plurality of cameras/lenses configured to receive real-time video from each of the plurality of cameras or lenses. A partial field-of-view virtual reality headset or a mixed reality headset is electronically coupled to the central processing unit. The headset displays real-time video from a select portion of the plurality of cameras or lenses, which provides 360 degree omnidirectional visualization based upon a position of the headset.Type: GrantFiled: April 10, 2018Date of Patent: April 13, 2021Inventor: James X.

Patent number: 8445383Abstract: A heterojunction between thin films of NCD and 4H—SiC was developed. Undoped and B-doped NCDs were deposited on both n? and p? SiC epilayers. I-V measurements on p+ NCD/n? SiC indicated Schottky rectifying behavior with a turn-on voltage of around 0.2 V. The current increased over eight orders of magnitude with an ideality factor of 1.17 at 30° C. Ideal energy-band diagrams suggested a possible conduction mechanism for electron transport from the SiC conduction band to either the valence band or acceptor level of the NCD film.Type: GrantFiled: September 5, 2008Date of Patent: May 21, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Karl D.
