  • System and method for creating a performance tool and a performance tool yield
    Patent number: 7444627
    Abstract: A system and method for generating a performance tool includes a builder, a seeker, and a catalyst. The builder is used to generate the seeker. The seeker is selected for operation, thereby launching the catalyst. The catalyst runs the seeker and receives assertions, such as selected answers, in response to interrogatives, such as questions. When all assertions are provided to all interrogatives, the seeker generates a yield. However, the yield also can be generated dynamically as the seeker operates.

  • Thermal paper with security features
    Patent number: 5883043
    Abstract: A thermal paper with an image derived from a water-based security ink has more than one means of security. A variable light absorbing and/or transmitting pigment or dye in the ink is a first security and a water repelling agent in the ink is a second security. A pseudo-watermark from the coloration of the ink under ambient conditions is a third security. Visible images can be generated from the printed ink upon exposure to UV or infrared light. Methods of preparing the thermal paper comprise printing the security ink on thermal paper with only one thermosensitive coating on the surface opposite the thermosensitive coating.
