  • Publication number: 20190313163
    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.

  • Publication number: 20190019627
    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: 10020914
    Abstract: Apparatus and methods for maximizing utilization of a dynamically varying channel are provided. A transmitter comprising a video source encoder encodes and transmits data over one or more digital data channels. A forward error correction coder is associated with the video source encoder for error correction coding of one or more blocks of the data. The forward error correction coder receives the data from the video source encoder at an encoding data rate. The blocks of error correction coded data are transmitted at a predetermined transmitting rate over the one or more digital data channels to a receiving module. The encoding data rate of the data provided by the video source encoder to the forward error correction coder is modified to fully utilize available channel bandwidth of the one or more digital data channels while maintaining the predetermined transmitting rate of the error correction coded data.

  • Publication number: 20170336328
    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.
