  • Patent number: 9064147
    Abstract: Handwriting interpretation tools, such as optical character recognition (OCR), have improved over the years such that OCR is a common tool in business for interpreting typed text and sometimes handwritten text. OCR does not apply well to non-text-only diagrams, such as chemical structure diagrams. A method according to an embodiment of the present invention of interpreting a human-drawn sketch includes determining a local metric indicating whether a candidate symbol belongs to a certain classification based on a set of features. The set of features includes, as a feature, scores generated from feature images of the candidate symbol. Also included is determining a joint metric of multiple candidate symbols based on their respective classifications and interpreting the sketch as a function of the local and joint metrics.

  • Publication number: 20150111779
    Abstract: Described herein are methods and devices for capturing and determining the identity of molecules using nanopores. The molecules can be counted, sorted and/or binned rapidly in a parallel manner using a large number of nanopores (e.g., 132,000 nanopores reading 180 million molecules in 1 hour). This fast capture and reading of a molecule can be used to capture probe molecules or other molecules that have been generated to represent an original, hard to detect molecule or portions of an original molecule. Precise counting of sample molecules or surrogates for sample molecules can occur. The methods and devices described herein can, among other things, replace flow cytometers and other counting instruments (e.g., while providing increased precision and throughput relative to a flow cytometer).

  • Patent number: 8740819
    Abstract: Disclosed is an apparatus and corresponding method to capture individual representational motions made by a person while performing a neuropsychological test. A user of the apparatus and method may be allowed to view, edit, classify, and retrieve any captured and recorded motions made by the person. In one embodiment, a capture unit, such as a digitizer, captures the motions made by a person while performing a Clock Drawing Test, and the captured data may then be reported in a myriad of ways. The apparatus and method also provide a means to standardize administration and scoring of writing utensil and paper based neuropsychological testing administered to a person or control and test groups for domestic or international applications. By analyzing individual representational motions made by a person while performing a neuropsychological test, unexpectedly more information may be gleaned from the test than was available to physicians from only a completed drawing.

  • Publication number: 20140134616
    Abstract: This disclosure provides chips, systems and methods for sequencing a nucleic acid sample. Tagged nucleotides are provided into a reaction chamber comprising a nanopore in a membrane. An individual tagged nucleotide of the tagged nucleotides can contain a tag coupled to a nucleotide, which tag is detectable with the aid of the nanopore. Next, an individual tagged nucleotide of the tagged nucleotides can be incorporated into a growing strand complementary to a single stranded nucleic acid molecule derived from the nucleic acid sample. With the aid of the nanopore, a tag associated with the individual tagged nucleotide can be detected upon incorporation of the individual tagged nucleotide. The tag can be detected with the aid of the nanopore when the tag is released from the nucleotide.

  • Publication number: 20130244340
    Abstract: This disclosure provides systems and methods for molecular identification and polymer (e.g., nucleic acid) sequencing using nanopores. The polymer may be passed through or in proximity to the nanopore and various subunits of the polymer may affect the current flowing through the nanopore. The various subunits may be identified by measuring the current at a plurality of voltages applied across the nanopore and/or membrane. In some cases, the polymerization of tagged nucleotides presents tag molecules to the nanopore that can be identified by measuring the current at a plurality of voltages applied across the nanopore and/or membrane. Also provided herein are systems and methods for sequencing both the sense and anti-sense strand of a double stranded nucleic acid molecule with a nanopore and methods for using ribonucleic acid (RNA) speed bump molecules to slow the passage of a nucleic acid molecule through or in proximity to a nanopore.
