| 20080311057 | Bleaching Toothpastes and Methods for Making and Using Them - In toothpaste, the addition of the Iodide ion by way of iodide salts, such as sodium iodide and potassium iodide, to a peroxide such as hydrogen peroxide in a basic medium yields free radical oxygen and water; generating large amounts of heat and depleting the Hydrogen Peroxide in a matter of minutes. The free radical oxygen generated in this reaction can be utilized to oxidize organic molecules that produce offending stains on select items, including artificial teeth and other dental appliances. Once the free radical oxygen has oxidized the offending molecule the color is lost and the solubility changes allowing any loose fragments of the offending molecule to be washed away in the solvent. The iodide ion catalyzes the reaction allowing for precise control over the speed at which the stain is removed without the need for other expensive, cumbersome energy adding equipment such as lights, lasers, heat sources, etc. | 12-18-2008 |
| 20080205482 | METHOD AND TESTING EQUIPMENT FOR LEDs AND LASER DIODES - The present invention is a non-invasive method and associated apparatus for determining the junction temperature for an LED or laser diode (collectively “LED”). First a sample LED is placed in a heat chamber and the change of the LED's peak wavelength is recorded over time, as is the change in the temperature in the heat chamber. Since the heat chamber supplies the major component to the junction temperature, dwarfing the other components, it is a reasonable proxy for true junction temperature. The data is compiled to determine change of peak wavelength as a function of temperature and that function can then be used to determine junction temperature of similar LEDs that are installed in a system or manufactured. The invention may also be used to measure other useful data, such as power, output power changing with the junction temperature and intensity of the LED over time and may be used to estimate failure rate. | 08-28-2008 |
