  • Patent number: 10839156
    Abstract: Generally described, one or more aspects of the present application correspond to a machine learning address normalization system. A system of deep learning networks can normalize the tokens of a free-form address into an address component hierarchy. Feature vectors representing various characters and words of the address tokens can be input into a bi-directional long short term memory network (LSTM) to generate a hidden state representation of each token, which can be individually passed through a softmax layer to generate probabilistic values of the token being each of the components in the address hierarchy. Thereafter, a conditional random field (CRF) model can select a particular address component for each token by using learned parameters to optimize a path through the collective outputs of the softmax layer for the tokens. Thus, the free-form address can be normalized to determine the values it contains for different components of a specified address hierarchy.

  • Patent number: 9326711
    Abstract: A reflectance optical perfusion sensor may include at least one light source and a plurality of detector elements arranged in a planar or nonplanar configuration, such as a three-dimensional array. The detector elements may sense light emitted by the at least one light source and reflected by a blood mass of a patient, such as blood within a blood vessel. In some examples, the detector elements may be arranged such that photodetection surfaces of at least two of the detector elements are nonparallel. In addition to or instead of the nonplanar arrangement of detector elements, an optical perfusion sensor may include a detector array including a plurality of detector elements at least partially surrounding a light source. Varying the location and orientations of detector elements may help increase a quantity of light emitted by the at least one light source and reflected toward the optical perfusion sensor by blood.

  • Publication number: 20150152074
    Abstract: Furfural is produced by contacting a feedstock solution containing C5 sugar and/or C6 sugar with a solid acid catalyst using reactive distillation. Both high yield and high conversion are obtained, without production of insoluble char in the reaction vessel. Degradation of furfural is minimized by its low residence time in contact with the solid acid catalyst. Higher catalyst lifetime can be achieved because the catalyst is continually washed with the refluxing aqueous solution and not sitting in high-boiling byproducts like humins, which are known to be deleterious to catalyst lifetime.
