The method also includes obtaining a plurality of fractions of the passed fluid such that each of the fractions includes a major portion containing particles having similar size and shape and substantially free of particles having larger size and shape. The apparatus includes first and second substrates each of which has a surface containing a plurality of open, nanoscale channels disposed therein. The surfaces are bonded together such that each of the channels of the first substrate is in fluid communication with at least two of the channels of the second substrate and is misaligned relative to the channels of the second substrate.Type: GrantFiled: February 9, 2011Date of Patent: January 3, 2012Assignee: Intel CorporationInventor: Scott Sibbett -
Patent number: 8057672Abstract: Provided is a disposable multi-layered filtration device for the separation of blood plasma which can be applied to a biochip and appropriate for disposal uses. The filtration device for the separation of blood plasma includes: an upper substrate including a blood inlet; an intermediate substrate including a filtering unit for extracting blood plasma from blood flowing through the blood inlet; and a lower substrate including an air outlet, wherein the upper substrate, the intermediate substrate, and the lower substrate are stacked and adhered.Type: GrantFiled: June 4, 2008Date of Patent: November 15, 2011Assignee: Electronics and Telecommunications Research InstituteInventors: Kwang Hyo Chung, Yo Han Choi, Dae Sik Lee, Ju Hyun Jeon, Moon Youn Jung, Seon Hee Park

Patent number: 8038879Abstract: A fluid strainer device is disclosed. The device includes a housing which defines an open chamber, the chamber having both at least one fluid input port and at least one fluid outlet port. A plurality of spaced strainer baskets are disposed within the chamber. Each basket has a pair of spaced perforated side panels, a perforated rear panel, a perforated top panel and an open front portion in fluid communication with the chamber fluid input port. Finally, each strainer basket is aligned within the chamber for fluid flow from the chamber input port into the basket's open front portion and out through the perforations thereof to filter debris from the fluid while preventing substantial fluid pressure drop between the input and outlet ports substantially independent of debris buildup within the basket.Type: GrantFiled: October 16, 2007Date of Patent: October 18, 2011Inventor: Wayne Kraft

Publication number: 20110233148Abstract: A filter apparatus comprises a filter having first and second opposed surfaces. A first reservoir is positioned adjacent with the first surface and in communication with the first surface, and a first inlet-outlet port is in communication with the first reservoir and spaced from the first surface. A second reservoir is positioned adjacent the second surface, and in communication with the second surface, and a second inlet-outlet port is in communication with the second reservoir and spaced from the second surface. A filter plate system comprises a reservoir plate. The reservoir plate comprises at least one reservoir well. The filter plate system further comprises a strainer plate. The strainer plate comprises at least one strainer well, which is removably receivable in the reservoir well. The strainer well comprises at least one mesh wall portion.Type: ApplicationFiled: December 16, 2009Publication date: September 29, 2011Applicant: STEMCELL TECHNOLOGIES INC.Inventors: Jennifer Antonchuk, Cindy Miller

Patent number: 8017004Abstract: A filter system for a storm drain having a bottom, side walls, and an outlet formed in the side wall. The filter system includes a main section having an array of openings formed therein for permitting water to flow through the filter. The main section is configured to be mounted adjacent the side wall and aligned with the outlet. In some cases, the bottom of the storm drain includes a depression for feeding water to the outlet. The filter system includes a flexible mesh that extends from the bottom of the main section into the depression for filtering water flowing in the depression. In addition, the filter system includes a mounting structure that enables the main section to be slidably mounted into an operative position and also enables the main section to be removed by slidably moving it from the operative position.Type: GrantFiled: August 17, 2009Date of Patent: September 13, 2011Assignee: Trash Guard, Inc.Inventor: John M. Crumpler
