  • Patent number: 10169838
    Abstract: A method, computer program product, and system for generating and embedding a watermark in digital video frame include a processor obtaining a request to generate a watermark and embed the watermark in a digital video frame captured by a first monitor. Based on obtaining the request, the processor fetches from one or more pre-defined regions of a memory resource, digital video data captured by at least two monitors, where a timestamp of the digital video data is equal to a timestamp of the digital video frame. The processor generates a watermark from the digital video data by calculating a binary result of the digital video data. The processor embeds the watermark (binary result) in the digital video frame.

  • Patent number: 10116231
    Abstract: Power supply units (PSU) provide for digital current-sharing loop control to ensure output voltage regulation during dynamic load transients by (i) delaying an internal current signal to match a delay in a shared current signal, and (ii) controlling the output amplifier based on the shared current signal and the delayed local current signal to maintain the respective local DC electrical power in proportion to contributions by other ones of the more than one PSU to the shared DC electrical power and thereby avoid instability in dynamic response to a load transient induced by the power consuming component.

  • Publication number: 20170283524
    Abstract: A method for making a sulfur based cathode composite material is disclosed. Polyacrylonitrile and elemental sulfur are dissolved together in a first solvent to form a first solution. An additive is added to the first solution to mix with the polyacrylonitrile and the elemental sulfur. The additive is at least one of metal and metal sulfide. An environment in which the polyacrylonitrile and the elemental sulfur are located in is changed to reduce a solubility of the polyacrylonitrile and the elemental sulfur in a changed environment to simultaneously precipitate the polyacrylonitrile and the elemental sulfur, thereby forming a precipitate having the additive. The precipitate is heated to chemically react the polyacrylonitrile with the elemental sulfur.

  • Patent number: 9388044
    Abstract: A method of producing stable disinfectant for use as a biocidal composition. The method comprises: providing reagents, asynchronously feeding the reagents into a wide space, and allowing all the reagents to come into contact and mix with each other. The reagents comprise: a) an amine source in concentrated form, b) an oxidizing halogen compound in concentrated form, and c) a diluent. The use of asynchronous feeding and a wide space results in a dynamic biocide regimen. This regimen results in a changing environment that infestations have difficulty adapting to. This method also imparts superior results due to the avoidance of channeling effects which would otherwise weaken the effects of the biocide.
