  • Publication number: 20140227783
    Abstract: A novel method for building complex three-dimensional scaffolds for biomimetic applications such as in vitro organ growth, using a gelatin/sugar/water gel, ultraviolet radiation, and heat or enzyme is described. The method produces gelatin-sugar hydrogels demonstrating greater thermal stability, mechanical strength, and resistance to enzymatic degradation. The invention also provides a means to assemble the gelatin sugar hydrogel films into complex three-dimensional structures (scaffolds). To account for the native biochemical factors present in natural scaffolds, methods of conjugating such factors to the gelatin-sugar hydrogel are described. These scaffolds can then be applied for tissue culturing and organ growth. The present invention also describes a system and apparatus for constructing these complex three-dimensional scaffolds by taking advantage of the physical and chemical properties of the gelatin-sugar hydrogel.

  • Patent number: 6971665
    Abstract: A head protective airbag which is adapted to not be inflated or to be scarcely inflated when dragged out of a pillar cover is provided. The airbag can be extremely smoothly pulled or dragged out of the pillar cover. The head protective airbag is provided with a triangular first cell in a front portion of the airbag. The first cell is in communication with a gas inlet through first and second gas passages. As an inflator is actuated, gas flows first mainly into the first gas passage through the gas inlet so that the airbag pushes and opens a roof trim above a B-pillar and thus starts to deploy into a vehicle cabin. The first cell is pulled by the first gas passage and an area around the first gas passage so as to tear a trim of an A-pillar and come out of the trim. After that, the first cell is inflated.
