  • Flame retardant building construction material and process
    Patent number: 12104385
    Abstract: Disclosed is a building and construction material and process including multiple layers and vermiculite ore in at least one layer. A substrate layer may have one or more layers on top or on the bottom of it. Numerous compounds may be used in one or more of the layers including asphaltic compound, polymer modified asphalt compound, thermoplastic polymer compound and others. The layers may also include synergistic flame retardant and fillers. And disclosed is a process to manufacture the building and construction material.
    Type: Grant

  • Apparatus and method for visible imaging using Darlington phototransistors
    Publication number: 20060076646
    Abstract: The present invention is a modified darlington phototransistor wherein a phototransistor is coupled to a Bipolar Junction Transistor (BJT). This design provides a high sensitivity and a fast response and effectively increases the gain of the photocurrent. This circuit is particularly will suited for the readily available CMOS and Bipolar Complementary Metal Oxide Semiconductor (BiCMOS) processes prevalent today.
