  • Patent number: 11989001
    Abstract: One or more video gateway devices configured to: access pre-configured criteria including at least a first condition, a second condition, and a first event; access video content captured by cameras configured to capture video of areas of a manufacturing facility; determine, based on an analysis of the video content, that the first condition is satisfied; access sensor data from one or more sensors; determine, based on an analysis of the sensor data, that the second condition is satisfied; and based on determining that the first and second conditions are satisfied, cause the first event to be executed.

  • Patent number: 4445951
    Abstract: A method of manufacturing a composite material in which layers of reinforcing filaments are stitched across with filaments of a thermoplastic polymer and then interposed between sheets of the same thermoplastic polymer as that used to stitch across the reinforcing filaments. The resultant stack is then heated under pressure for sufficient time for the thermoplastic polymer to impregnate the reinforcing filaments whereupon the thus formed composite is cooled under compression in order to avoid any distortion thereof.

  • Patent number: 4380523
    Abstract: A method of manufacturing a composite material which comprises filaments enclosed in a matrix of a high temperature resistant thermoplastic polymer. The method entails impregnating the filament with a first high temperature resistant thermoplastic polymer in an amount sufficient only to lightly bind the fibres together. The bound fibres are then interposed between sheets of a second thermoplastic polymer and the whole structure subjected to heat and pressure for a time sufficient to ensure impregnation of said second thermoplastic polymer into said filaments and diffusion of the first thermoplastic polymer into the second thermoplastic polymer.
