Publication number: 20200379739Abstract: Processing external code includes: parsing the external code to identify a first semantic entity, mapping the first semantic entity to a second semantic entity, the first semantic entity comprising a first set of one or more specified attributes and the second semantic entity comprising a second set of one or more attributes that are capable of being specified, determining that a first attribute of the second set of one or more attributes does not have a corresponding specified attribute within the first set of one or more specified attributes, determining available information for specifying the first attribute of the second set of one or more attributes, and storing the second semantic entity in association with the first attribute of the second set of one or more attributes specified based on user selection or specifying the first attribute in response to available information provided to a user interface system.Type: ApplicationFiled: May 31, 2019Publication date: December 3, 2020Inventors: Vivek Bhownani, Alexander C. Feinman, Fazil Peermohammed, David A. Foti, Ebrahim Mehran Mestchian, Yao Ren, Vijaya Raghavan, Peter S.

Patent number: 10369566Abstract: A composition made of at least 60 wt. % of a thermoplastic elastomer resin and additives that are solid at least from 0-50° C., that has a Shore A hardness that is less than about 50 bears a patterned surface, the pattern comprising at least one microfluidic channel having a cross-sectional dimension smaller than 100 microns is a substrate for forming a microfluidic device. The chief advantages of such compositions are: its ability to bond in a sealing manner to smooth surfaces of many different compositions, its ease of manufacture and microstructure patterning, and its general impermeability to liquids.Type: GrantFiled: January 6, 2016Date of Patent: August 6, 2019Assignee: National Research Council of CanadaInventors: Emmanuel Roy, Teodor Veres

Patent number: 9498914Abstract: The invention provides a new process for patterning TPE membranes for use in the design and fabrication of 3D microfluidic devices. The process involves patterning a TPE material without permitting the highest features of the mold to come into contact with the counter-plate, whereby adhesion between the TPE and the mold or counter-plate during demolding results directly in removal of the excess layer from the TPE membrane to produce well formed micrometric-sized open-through holes in the TPE membrane. The process permits rapid, reliable and efficient patterning of densely packed and arbitrarily placed micrometric open-through holes and channels of high aspect-ratio and any shape or wall profile in thin TPE membranes.Type: GrantFiled: February 15, 2011Date of Patent: November 22, 2016Assignee: National Research Council of CanadaInventors: Daniel Brassard, Emmanuel Roy, Kebin Li, Teodor Veres

Patent number: 9435490Abstract: A microfluidic valve operable to semi-permanently close a channel of a microfluidic device defined between a thermoplastic elastomer (TPE) film and a substrate operates employs a surface contact bond between the TPE and a wall of the channel. Thermomechanical release of the valve, tristate functionality, and repeated semi-permanent closure and release are demonstrated.Type: GrantFiled: April 26, 2010Date of Patent: September 6, 2016Assignee: National Research Council of CanadaInventors: Jean-Christophe Galas, Emmanuel Roy, Teodor Veres

Publication number: 20140134631Abstract: A centrifugal microfluidic device is provided having a microfluidic circuit, a fluid reservoir for providing fluid in the microfluidic circuit, a hydrodynamic resistance element in fluid communication with the reservoir for controlling rate of flow of a fluid out of the reservoir, and a siphoned chamber in fluid communication with the hydrodynamic resistance element and the microfluidic circuit for receiving fluid from the hydrodynamic resistance element and for delaying and metering of the fluid into the microfluidic circuit. The microfluidic device is useful for performing a biological assay. Operation of the device is completely independent on the liquid-solid contact angle and wetting properties of the liquids on the solid material of the platform, and the device does not need a carefully controlled rotation protocol.Type: ApplicationFiled: March 22, 2012Publication date: May 15, 2014Applicant: NATIONAL RESEARCH COUNCIL OF CANADAInventors: Liviu Clime, Maxence Mounier, Emmanuel Roy, Teodor Veres

Patent number: 8303911Abstract: A microfluidic system for processing a sample includes a microfluidic CD in the form a rotatable disc, the disc containing a plurality of separate lysis chambers therein. A magnetic lysis blade and lysis beads are disposed in each of the lysis chambers and a plurality of stationary magnets are disposed adjacent to and separate from the microfluidic CD. The stationary magnets are configured to magnetically interact with each of the magnetic lysis blades upon rotation of the microfluidic CD. Each lysis chamber may have its own separate sample inlet port or, alternatively, the lysis chambers may be connected to one another with a single inlet port coupled to one of the lysis chambers. Downstream processing may include nucleic acid amplification using thermoelectric heating as well as detection using a nucleic acid microarray.Type: GrantFiled: October 14, 2010Date of Patent: November 6, 2012Assignee: The Regents of the University of CaliforniaInventors: Jonathan P. Siegrist, Robert A. Gorkin, III, Regis Peytavi, Marc Madou, Horacio Kido, Mary Amasia, Emmanuel Roy, Teodor Veres
