  • Patent number: 9275559
    Abstract: An identification medium is optimized for displaying visible and excitable indicia. The medium includes a substrate having a color change layer, such as a direct thermal layer, and a patterned excitable layer placed over the color change layer. The color change layer produces the visible indicia. The excitable layer produces the excitable indicia. The excitable indicia is not easily readable under ambient light but becomes more easily readable under directed radiation, i.e., UV or IR light.

  • Patent number: 7827983
    Abstract: A method of making a pharmaceutically active ingredient abuse-prevention device includes providing a pharmaceutically active ingredient and providing an antagonist of the pharmaceutically active ingredient. The antagonist is in selective fluid communication with the pharmaceutically active ingredient. Electronic circuitry is configured to selectively operate the fluid communication between the antagonist and the pharmaceutically active ingredient so as to mix the pharmaceutically active ingredient with the antagonist upon recognition of one or more predetermined fault conditions. Mixing the pharmaceutically active ingredient with the antagonist renders the pharmaceutically active ingredient substantially ineffective.
