  • Patent number: 11627911
    Abstract: An evaluation system including a hardware system for collecting real-time data for evaluating sleeping comfort performance of a bedding system is disclosed. The hardware system includes a thermal and moisture comfort measurement system, a thermal and moisture comfort control system, a biomechanical comfort control system, and a biomechanical comfort measurement system. The evaluation system also includes a computational system having a processor and a tactile database, and a portable device. The computational system is configured to receive and process the real-time data from the hardware system, and is communicatively connected to the portable device for transmitting real-time data for evaluating the bedding system and adjusting the hardware system.

  • Publication number: 20220112655
    Abstract: A method and an integrated system for dyeing synthetic, natural, and blended textiles in the form of fabrics, yarns, and garments are provided. The integrated system includes a first pressurizing pump for pressurizing liquefied CO2 to supercritical CO2 (Sc—CO2); a second pressurizing pump for pressurizing CO2 to liquefied CO2; a liquefied CO2 storage vessel for storing the liquefied CO2 and the separated liquefied CO2 from the one or more cyclone separators; a heater for heating the Sc—CO2; a dyestuff vessel for mixing a dyestuff and the Sc—CO2 to obtain Sc—CO2-mixed dyestuff; a dyeing vessel for dyeing the textile by circulating the Sc—CO2 and the Sc—CO2-mixed dyestuff between the dyeing vessel and the dyestuff vessel; and one or more cyclone separators for removing the dyestuff from the Sc—CO2-mixed dyestuff to obtain separated liquefied CO2.
