  • Patent number: 9418144
    Abstract: Systems and methods are disclosed for performing duplicate document analyses to identify texturally identical or similar documents, which may be electronic documents stored within an electronic discovery platform. A process is described which includes representing each of the documents, including a target document, as a relatively large n-tuple vector and also as a relatively small m-tuple vector, performing a series of calculations on the set of m-tuple vectors to identify a set of documents which are candidate near-duplicates to the target document, and then filtering the candidate set of near-duplicate documents based upon the distance of their n-tuple vectors from the n-tuple vector of the target document.

  • Patent number: 9412574
    Abstract: An apparatus for mass spectrometry includes a laser ablation sampler comprising a laser ablation chamber and a laser which produces a laser beam. The laser irradiates and ablates a material from a sample placed within the laser ablation chamber so as to generate an ablated sample material. A transfer tube system comprising transfer tubes connect the laser ablation sample with, and provides a parallel and simultaneous transport of the ablated sample material to, each of a soft and a hard ionization source. The soft and hard ionization sources interact with the ablated sample material to respectively generate ion populations having a mass-to-charge ratio distribution. These respective mass-to-charge ratio distributions are respectively transmitted to a molecular mass spectrometer and to an elemental mass spectrometer which provide information on the mass-to-charge ratio distribution. The mass-to-charge ratio distributions are used to characterize a composition of the ablated sample material.
