  • Patent number: 7731967
    Abstract: The invention provides, inter alia, immunogenic compositions comprising a first antigen, at least two adjuvants, wherein a first adjuvant comprises a polymer derived from poly(lactides) and/or poly(lactide-co-glycolides), and wherein a second adjuvant comprises an imidazoquinoline, wherein said first antigen is encapsulated within, adsorbed or conjugated to, co-lyophilized or mixed with said first adjuvant, and a pharmaceutically acceptable excipient, wherein said composition elicits a cellular immune response when administered to a vertebrate subject. The invention also provides methods of producing immunogenic compositions, methods for producing a cytotoxic-T lymphocyte (CTL) response in a vertebrate subject, and methods of immunization.

  • Publication number: 20100000397
    Abstract: A perforating system has a perforating module comprising a unitary body of explosive. The explosive is contained within a non-explosive casing, or liner, having formed indentations and a cover thereover. The indentations, which will transform into explosively formed penetrators (EFP's) upon detonation, have a perimeter shape that allows for improved packing density, e.g., a hexagonal perimeter, which results in relatively little “dead space” wherein no perforating penetrators are generated. In operation, the module provides a relatively dense shot pattern and substantially reduced amount of post-detonation debris that could clog the perforations and/or require remedial clean-up or repeat perforation.

  • Patent number: 7116798
    Abstract: A substrate card, in the form of a Metrocard®, farecard, keycard, passport, boarding pass or the like, presented for controlled gateway passage at an automatic reader, is photographed and the captured card image is digitized. The card then is heated to a point where trace explosive present on the card is subjected to an energetic reaction imparting a char smudge signature. The card is cooled and a second image is captured and digitized. The digitized images are subjected to a subtractor stage resulting in an isolated char smudge signature image possibly in the form of at least a partial fingerprint residue recognizable by a computer. Upon char image detection, which may include a fingerprint matching process, the computer directs the controlled gateway to restrain the card presenter and secure the card as evidence. The card may be pre-coated to avoid ignition and to enhance trace material adhesion.
