  • Patent number: 11385147
    Abstract: A method and filtering system are described. The filtering system comprises a vacuuming plate having a base with a plurality of outlet openings extending therethrough, a plurality of walls extending from the base to define a cavity, and a vacuum port in fluid communication with the cavity; and a filtering unit mounted to the vacuuming plate and enclosing the cavity. The filtering unit comprises a filter plate with a plurality of filter openings extending therethrough and aligned with the outlet openings; a filtering membrane extending across the filter plate and covering the plurality of filter openings; and a piercing plate on the filter plate maintaining the filtering membrane therebetween, the piercing plate having a plurality of vessel piercing members extending away from the filtering membrane, the vessel piercing members having conduits extending through the piercing plate, the conduits aligned with the filter openings to allow fluid flow therebetween.

  • Publication number: 20200292567
    Abstract: There is described an integrated system for processing vessels containing samples. The integrated system generally has: a frame; a reagent dispensing station, a sample digestion station, a sample cooling station, a sample normalization station and a sample filtration station within the frame; a vessel manipulation unit having a vessel manipulating member displacing the vessels containing the samples between the reagent dispensing station, the sample digestion station, the sample cooling station, the sample normalization station and the sample filtration station; and a controller communicatively coupled to the vessel manipulation unit, the controller having a processor and a memory having stored thereon instructions which when executed by the processor displace the vessels containing the samples from one station to another.

  • Patent number: 9762828
    Abstract: An imager includes a flat panel configured to collect charges when the imager operates in a full-power charge integration mode. The imager switches to a low-power standby mode immediately after each image acquisition in the full-power charge integration mode. Bias current flowing through the flat panel is monitored in the standby mode. The imager switches to the full-power charge integration mode when detecting a change in the bias current indicating onset of an X-ray exposure.

  • Publication number: 20050288882
    Abstract: Systems and methods of processing data generated using multi-gain detectors are disclosed. These systems and methods include separate gain images and separate offset images associated with each dynamic range of a multi-gain detector. These images are applied to multi-gain raw data to generate multi-gain corrected data. Some embodiments of the invention further include systems and methods of generating and using a multi-gain look-up table configured for generating viewable data from multi-gain corrected data. Some embodiments of the invention further include systems and methods of generating a global gain ratio for converting multi-gain data to non-multi-gain data.
