Patent number: 11660571Abstract: A microfluidic chip device for the purification of radiochemical compounds includes a chip having an injection channel and intersecting branch channels with a plurality of valves are located along the injection channel and branch channels and configured to retain a plug of solution containing the radiochemical compound. The chip further includes a serpentine channel segment (for separation) coupled to the output of the injection channel. A high voltage power source advances the plug of solution through the purification region and into the downstream fraction collection channel. The chip includes a downstream fraction collection channel coupled to the serpentine channel segment and having an optical and radiation detection regions. One or more branch fraction channels intersect with the fraction collection channel and include valves located therein so that the radiochemical compound that is detected using a radiation detector is directed into the desired branch fraction channel for subsequent use.Type: GrantFiled: November 14, 2017Date of Patent: May 30, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: R.

Patent number: 11577333Abstract: A method of connecting two CMC substrates that includes providing two substrates; placing one substrate approximate to the other substrate, such that at least a portion of the two substrates overlap and define a brazing area; placing a brazing material approximate the brazing area; defining a primary raster pattern that encompasses the brazing area and a portion of the two substrates outside the brazing area; defining a secondary raster pattern that encompasses the brazing area; allowing a laser to scan the primary raster pattern to preheat the brazing area to a temperature below the brazing material's melting point; allowing the laser to scan the secondary raster pattern to heat the brazing area to a temperature that is above the brazing material's melting point; melting and allowing the brazing material to flow within the brazing area; and cooling the brazing area to form a brazed joint connecting the two substrates.Type: GrantFiled: January 16, 2020Date of Patent: February 14, 2023Assignees: ROLLS-ROYCE CORPORATION, TRUSTEES OF THE COLORADO SCHOOL OF MINESInventors: Scott Nelson, Raymond Xu, Stephen Liu, Juan Carlos Madeni, Brian Paul Rodgers

Publication number: 20080107041Abstract: Method and apparatus for tracking, recording and distributing link state characteristics over communications networks. The invention allows network operators to efficiently define, track, store and disseminate link state characteristics using a bit-field-encoded resource record that is capable of representing many more link state characteristics than the bit-mask-encoded records used in existing systems. As a result, the present invention, when used in conjunction with standard routing and network maintenance algorithms, provides a much more efficient method than existing systems provide, for performing sophisticated networking tasks, such as handling complicated information transmission requests, setting up and tearing down network paths, and making dynamic routing decisions.Type: ApplicationFiled: December 27, 2007Publication date: May 8, 2008Applicant: Verizon Laboratories, Inc.Inventor: Stephen Liu
