  • System for determining biofuel concentration
    Patent number: 9442101
    Abstract: A measurement device or system configured to measure the content of biofuels within a fuel blend. By measuring a state of a responsive material within a fuel blend, a biofuel content of the fuel blend may be measured. For example, the solubility of a responsive material to biofuel content within a fuel blend, may affect a property of the responsive material, such as shape, dimensional size, or electrical impedance, which may be measured and used as a basis for determining biofuel content.
    Type: Grant

  • Detection of latent prints by Raman imaging
    Patent number: 7869031
    Abstract: The present invention relates to a method for detecting a print on a surface, the method comprising: (a) contacting the print with a Raman surface-enhancing agent to produce a Raman-enhanced print; and (b) detecting the Raman-enhanced print using a Raman spectroscopic method. The invention is particularly directed to the imaging of latent fingerprints.

  • Stripping ethanol from ethanol-blended fuels for use in NOSCR
    Patent number: 7257945
    Abstract: A method to use diesel fuel alchohol micro emulsions (E-diesel) to provide a source of reductant to lower NOx emissions using selective catalytic reduction. Ethanol is stripped from the micro emulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel (and other lean-burn) engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.
