  • Publication number: 20100171951
    Abstract: An spectrometer including Raman and LIBS spectroscopy capabilities is disclosed. The spectrometer includes a laser source configurable to produce a lased light directable towards a target substance, the laser source having a single wavelength and having sufficient power to cause a portion of the target to emit Raman scattering and sufficient to ablate a portion of the target substance to produce a plasma plume. A separate remote light collector is optically configurable to collect light emitted from the portion of the target emitting Raman scattering and from the portion of the target producing the plasma plume. A filter is optically coupled to the remote light collector to remove reflected light and Rayleigh-scattered light, and a spectroscope is optically coupled to the filter and configured to separate the collected and filtered light into a frequency spectrum comprising a Raman spectrum and a laser-induced breakdown spectrum. Finally, an electronic light sensor is used to record the frequency spectrum.

  • Publication number: 20100091188
    Abstract: System and method for synchronizing one or more secondary decoded media streams to a primary decoded media stream. The system includes a media stream processor and a mixer. The media stream processor receives a primary decoded media stream and secondary decoded media streams. The media stream processor synchronizes the secondary decoded media streams with the primary decoded media stream. The output of the media stream processor is coupled to the mixer. The mixer receives its second input from the primary decoded media stream. The mixer mixes the received streams and generates a PTS value for its output media stream by extrapolating the PTS of the primary decoded media stream.
