  • Patent number: 11524637
    Abstract: A vibration reduction device having an acoustic meta structure mounted to a vehicle body and configured to block a structure-borne noise transmitted through the vehicle body may include a plurality of unit structures arranged at a predetermined interval therebetween, wherein each of the unit structures includes frame mounted to the vehicle body and configured to separate a predetermined space into a predetermined number of separate sections formed by walls of the frame; and a vibrator formed at a corner portion of each of the separate sections and each of which has a natural frequency to block a vibration transmitted from the vehicle body through the frame.

  • Patent number: 10407623
    Abstract: The disclosure describes a one-step liquid biphasic catalytic process for converting a carbohydrate-containing feedstock, preferably lignocellulose, to light naphtha (e.g., hexane, pentane, methyl cyclopentane, cyclohexane, etc.) in the presence of an acidic reactive aqueous phase and a redox catalyst in the organic extracting/reaction phase. The process provides a cost-effective route for producing light-naphtha components, in presence or not of deoxygenates. The light naphtha components are useful as feedstock for steam and catalytic cracking to produce value-added platform molecules like ethylene and propylene, as precursor for the synthesis of bioaromatics like benzene and as gasoline fuel feedstock, and as fuel additives (e.g., the concomitantly formed oxygenates) to improve the biological origin of carbon in the fuel.

  • Patent number: 9155514
    Abstract: Reconstruction in positron emission tomography is performed with partially known attenuation. A PET-CT scanner is used to generate a PET image with time of flight emission information. To limit x-ray dose while providing increased sensitivity at the ends of the CT volume in the PET image, attenuation coefficients for oblique LORs passing outside the CT volume are determined from the time of flight emission information. The attenuation coefficients for LORs within the CT volume are derived from the CT data. An objective function may be maximized for the emission distribution without reconstructing the attenuation distribution.
