  • Patent number: 8417959
    Abstract: The present disclosure relates to an apparatus and/or method of identifying a user comprising illuminating a user with electromagnetic energy to induce luminescence and producing an output data signal. A reference data signal corresponding to the luminescence of a selected user may be identified and compared to the output data signal. In such a manner, an identification may be made as to whether a selected user is present.

  • Patent number: 8134127
    Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include a non-laser light source and thermal imaging camera that allow for detection of a target gas (or gasses) that absorbs at least some of the light source's wavelengths of operation. The light source can be implemented, for example, with an incoherent infrared (IR) light source, such as a resonance lamp configured with a gas cell containing a volume of a gas that, when excited by electric discharge, emits a wavelength that is absorbed by the target gas.

  • Patent number: 8085301
    Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.

  • Patent number: 6836502
    Abstract: A light source for a spectroscopy unit that measures tissue includes a block for engaging tissue and a light source. The block is formed of translucent material. The light source is positioned in close proximity to the block either directly or through use of a light fiber. The light source produces light at a single wavelength or small range of wavelengths shorter than the desired range of wavelengths to be produced by the light source for the spectroscopy unit. A luminescent material is placed in the light path between light source and the tissue to produce the desired wavelength of light when pumped by the light source.
