  • Methods and systems for detecting and/or determining the concentration of a fluid
    Patent number: 7768646
    Abstract: Methods and systems detect the presence of a fluid, such as water, based on a reflection of optical energy from the fluid. Methods and systems also determine the concentration of a constituent element in a mixture based on a reflection of optical energy from the mixture.

  • Systems and methods for generating optical energy using a light-emitting diode
    Patent number: 7671539
    Abstract: Systems for providing optical energy comprise an LED, a detector of optical energy, such as a photodiode, that measures the intensity of optical energy emitted by the light-emitting diode, and a controller. The controller adjusts the intensity of the optical energy emitted by the LED based on the intensity measurement provide by the photodiode, to maintain the intensity of the emitted optical energy at a desired level.
