  • Patent number: 12292327
    Abstract: A near-field probe (and associated method) compatible with near-infrared electromagnetic radiation and high temperature applications above 300° C. (or 500° C. in some applications) includes an optical waveguide and a photonic thermal emitting structure comprising a near-field thermally emissive material coupled to or part of the optical waveguide. The photonic thermal emitting structure is structured and configured to emit near-field energy responsive to at least one environmental parameter of interest, and the near-field probe is structured and configured to enable extraction of the near-field energy to a far-field by coupling the near-field energy into one or more guided modes of the optical waveguide.

  • Patent number: 12281989
    Abstract: 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.

  • Publication number: 20240129586
    Abstract: 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.

  • Patent number: 11463747
    Abstract: 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.

  • Patent number: 11342131
    Abstract: 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.

  • Patent number: 11317164
    Abstract: 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.

  • Patent number: 11317173
    Abstract: 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.
