Publication number: 20240129586Abstract: Systems and methods for controlling video functions across multiple video streams are provided. Multiple video streams are recorded at an event via a corresponding multiple of video sources, the multiple video streams being synchronized in time with each other. The multiple video streams are displayed on a display device. One or more of the multiple video streams may be selected via a touch screen of the display device, which are then presented for playback on the display device. Control of video functions of the selected video streams is enabled via finger gestures on the touch screen of the display device. The video functions may comprise video selection, play, pause, fast forward, rewind, zoom, focus, shuttle, scrub, seek, frame advance, and the like. In the event two or more of the multiple video streams are selected, the two or more video streams may be controlled simultaneously and synchronously.Type: ApplicationFiled: July 10, 2023Publication date: April 18, 2024Inventors: Paul Shen, Jared Timmins, Luc Comeau, Robin Wu

Patent number: 11467095Abstract: An infrared detection camera for the inspection of coated substrates. A corrosion sensing instrument is handheld, portable, battery powered, compact and lightweight. The camera performs nondestructive, real time imaging of corrosion and defects beneath painted metal or plastics or composite surfaces. The device includes a user-friendly computer interface for real time imaging and image storage capability and is typically used for detecting early stage corrosion beneath painted aircraft aluminum surfaces. The handheld device has a front “open air” imaging port which is designed to be placed in soft contact against the painted surface to be inspected by the instrument. The device includes an infrared camera and infrared lighting to capture an image of the surface. The captured image is transferred to a computer and analyzed to locate imperfections below a coating on a surface.Type: GrantFiled: September 20, 2021Date of Patent: October 11, 2022Assignee: LASER & PLASMA TECHNOLOGIES, LLCInventors: Mool C.

Patent number: 11463747Abstract: The present invention relates to a cloud-based video production system and corresponding methods that deliver real time or near real time video with broadcast quality. Video from the same source is encoded into at least two separate streams, one with low latency and another with higher latency and higher quality. Corresponding frames of each stream have identical timestamps. The two streams are sent over separate signal paths. A first signal path is a real time control (RTC) path having low latency, and used to communicate the lower quality video content from video sources to a producer user interface. The second signal path provides the same video content at a higher video quality than that provided over the first signal path, but with longer latency. Commands from the user interface based on the lower latency stream can then be carried out on the higher latency stream.Type: GrantFiled: February 26, 2021Date of Patent: October 4, 2022Assignee: TVU Networks CorporationInventor: Paul Shen

Patent number: 11342131Abstract: Disclosed is a semiconductor-liquid junction based photoelectrochemical (PEC) cell for the unassisted solar splitting of water into hydrogen and oxygen gas, the solar-driven reduction of CO2 to higher-order hydrocarbons, and the solar-driven synthesis of NH3. The disclosed system can employ a photocathode based upon wurtzite hexagonal semiconductors that can be tailored with proper band alignment for the redox potentials for water, CO2 reduction, and NH3 production, and with bandgap energy for maximum solar absorption. The design maximizes the carrier collection efficiency by leveraging spontaneous and piezoelectric polarization in these materials systems to generate hot electrons within the photocathode. These electrons have sufficient excess energy, preserved at a designed energy capture region, to overcome the kinetic overpotential (surface chemistry limitation) required for the reactions to occur at a high rate.Type: GrantFiled: July 16, 2018Date of Patent: May 24, 2022Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Michael Wraback, Anand V. Sampath, Paul Shen, Vijay S. Parameshwaran

Patent number: 11317164Abstract: The present invention relates to methods and systems for broadcasting/multicasting of media content over a communication network using shared bandwidth available from peer-to-peer networking. The system may include one or more servers for delivering media content over the network for one or more media content programs. The media content comprises data packets. The one or more servers may provide IP multicasting information and tracking information for the data packets to all receiving devices requesting the media content. Any receiving devices that request the media content and that one of: (a) fail to subscribe to the IP multicasting channel; or (b) fail to receive all of the data packets for the media content over the IP multicasting channel, may use the tracking information to identify other of the receiving devices that have received the data packets and to request the data packets from at least one of the identified receiving devices.Type: GrantFiled: January 7, 2021Date of Patent: April 26, 2022Assignee: TVU Networks CorporationInventor: Paul Shen

Patent number: 11317173Abstract: A cloud-based video production system, methods, and apparatus are provided. Video sources are in communication with a cloud-based video production server and a remote user interface via a network. A control unit, which is located at or in communication with video production server, is in communication with the remote user interface. A buffer, corresponding to each of the video sources, is disposed between each of the video sources and the control unit to account for network delays. Commands for selecting and manipulating video content from the video sources are sent from the user interface to the control unit, each of the commands containing a command timestamp corresponding to the video timestamp of the video frame displayed on the user interface when the command is issued. The control unit executes each command at a time when the video timestamp at an output of the corresponding buffer corresponds to the command timestamp. The control unit outputs a video program in accordance with the commands.Type: GrantFiled: February 24, 2021Date of Patent: April 26, 2022Assignee: TVU Networks CorporationInventor: Paul Shen
