Patent number: 11688183Abstract: A neural network is configured to process image data captured by a vehicle-mounted camera. The neural network includes common processing layers (a trunk) and separate, parallelizable processing layers (branches). An object detection branch of the neural network is trained to detect objects that may be visible from the vehicle-mounted camera, such as cars, trucks, and traffic signs. A curve determination branch is trained to detect and parameterize salient curves, such as lane boundaries and road boundaries. The curve determination branch itself is configured with a trunk and branch architecture, having both common and separate processing layers. A first branch computes a likelihood that a curve is present in a given location of the image data and a second branch further localizes the curve within the given location if such a curve is present. Training of the different branches of the neural network may be decoupled.Type: GrantFiled: February 3, 2022Date of Patent: June 27, 2023Assignee: NETRADYNE, INC.Inventors: Michael Campos, Venkata Sreekanta Reddy Annapureddy, David Jonathan Julian, Veeresh Taranalli, Jonathan Albert Cox, Arvind Yedla

Patent number: 10989855Abstract: Described herein is an illumination device for projecting light in a predetermined illumination pattern on a surface. The illumination device includes a light module having a light source and a light pipe configured to transmit light in any suitable manner. The illumination device also includes a housing having a cavity, an entrance opening for receiving the light emitted from the light source, and an aperture at a second housing end. Within the housing between the entrance opening and the aperture is a screen at least partially disposed in the cavity, the screen having at least one opening defining a base pattern configuration corresponding to the predetermined illumination pattern. The light pipe is configured to selectively transmit light from the light source to the cavity and may be linear or non-linear such that the light source and the surface to be illuminated do not need to face one another.Type: GrantFiled: November 8, 2018Date of Patent: April 27, 2021Assignee: AGM Automotive, LLCInventors: Bradley Matthew Albert Cox, Cye David Bittner

Patent number: 10025123Abstract: The various technologies presented herein relate to various hybrid phononic-photonic waveguide structures that can exhibit nonlinear behavior associated with traveling-wave forward stimulated Brillouin scattering (forward-SBS). The various structures can simultaneously guide photons and phonons in a suspended membrane. By utilizing a suspended membrane, a substrate pathway can be eliminated for loss of phonons that suppresses SBS in conventional silicon-on-insulator (SOI) waveguides. Consequently, forward-SBS nonlinear susceptibilities are achievable at about 3000 times greater than achievable with a conventional waveguide system. Owing to the strong phonon-photon coupling achievable with the various embodiments, potential application for the various embodiments presented herein cover a range of radiofrequency (RF) and photonic signal processing applications. Further, the various embodiments presented herein are applicable to applications operating over a wide bandwidth, e.g. 100 MHz to 50 GHz or more.Type: GrantFiled: December 15, 2015Date of Patent: July 17, 2018Assignees: National Technology & Engineering Solutions of Sandia, LLCInventors: Peter Thomas Rakich, Heedeuk Shin, Ryan Camacho, Jonathan Albert Cox, Robert L.

Patent number: 9261647Abstract: Quasi-phase matched (QPM), semiconductor photonic waveguides include periodically-poled alternating first and second sections. The first sections exhibit a high degree of optical coupling (abbreviated “X2”), while the second sections have a low X2. The alternating first and second sections may comprise high-strain and low-strain sections made of different material states (such as crystalline and amorphous material states) that exhibit high and low X2 properties when formed on a particular substrate, and/or strained corrugated sections of different widths. The QPM semiconductor waveguides may be implemented as silicon-on-insulator (SOI), or germanium-on-silicon structures compatible with standard CMOS processes, or as silicon-on-sapphire (SOS) structures.Type: GrantFiled: August 28, 2013Date of Patent: February 16, 2016Assignee: Sandia CorporationInventors: Johathan Albert Cox, Peter Thomas Rakich
