  • Publication number: 20140358025
    Abstract: The present invention relates to the design and implementation of a seizure detection system. In this invention, a reliable way to detect seizures is presented. The proposed invention filters an EEG signal by a Prediction Error Filter. The output of the prediction error filter is subjected to wavelet decomposition. Various features are then extracted from the wavelet coefficients. These features are input to a classifier to detect seizures. The proposed algorithm takes advantage of high sensitivity in detecting seizures and low complexity in implementation. The proposed scheme is general and is suitable for creating a trigger for therapy delivery in a closed-loop therapy system. The therapy could involve either delivery of an anti-epileptic drug or electrical or magnetic stimulation of the brain.

  • Publication number: 20090272674
    Abstract: The present invention provides nano zeolite containing hydrotreating catalyst and methods of preparation, and more particularly to a nano-sized zeolite beta composite hydrotreating catalyst. The hydrotreating catalyst for desulfurization of diesel distillates includes between about 5 to about 75 wt % nano-sized zeolite beta composite, about 10 to about 30 wt % of a hydrogenation metal/alloy and between about 5 to about 20 wt % binder.

  • Publication number: 20060074254
    Abstract: A method of extracting taxane products from biomass, which involves feeding the biomass into an pressurized liquid extraction unit and contacting the biomass with a halogenated C1 to C2 alkane solvent at a temperature of 100° C. or less and at sufficient pressure to keep the solvent in liquid form, to extract a stream of taxanes and solvent. The stream of taxanes and solvent are then cooled arid the solvent is stripped from the taxanes. The taxanes are finally passed through either a normal phase liquid chromatograph or a reverse phase liquid chromatograph.
