  • Patent number: 11821792
    Abstract: A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.
    Type: Grant

  • Publication number: 20070080078
    Abstract: A rupturable seal includes a first and second thermoplastic polymer layer and a third continuous polymer layer between the first and second polymer layers. The third polymer layer forms a first physical polymer blend with the first layer, and forms a second physical polymer blend with the second layer. The third layer can include a continuous fibrous strip of nonwoven polymeric microfibers, which may melt within a sealing region. Methods of making such seals and multi-compartment containers comprising such seals are disclosed. Applications for food storage and preparation and other diverse end uses are disclosed.
