Patent number: 11480398Abstract: The present invention is directed to a manifold for directing cooling fluid and/or gas to a heat exchanger in a flow configuration designed to optimize heat transfer from the heat exchanger. The manifold can take many different forms such as a layered construction with distributed inlet paths, local outlet paths, a central collection changer and a path for fluid removal. The manifold can be formed from a metal, plastic, rubber, ceramic, or other heat resistant material known to or conceivable by one of skill in the art. The manifold can also be combined with any type of heat exchanger known to or conceivable by one of skill in the art to form a thermal management unit. To optimize overall properties such as low pressure drop, high heat transfer, and excellent temperature uniformity of the thermal management unit, the manifold can be graded, expanded and scaled as needed.Type: GrantFiled: May 23, 2016Date of Patent: October 25, 2022Assignee: The Johns Hopkins UniversityInventors: Kevin J. Hemker, Timothy P. Weihs, Stephen Ryan, Longyu Zhao, Seunghyun Ha, Yong Zhang, James K. Guest

Patent number: 11209390Abstract: A volumetric microfluidic injector for capillary electrophoresis (CE) for highly repeatable sample injection has been designed and built to eliminate known injection bias in hydrodynamic injection. A defined volume from 1-10 nL or 0.1-100 nL of sample is confined in a defined region of a micro-valve PDMS microfluidic injector chip and electrophoretic potential is applied to drive sample into a separation device such as an embedded fused silica capillary for separation and detection. Using a 75 ?m ID capillary, the RSD of an absorbance peak area as low as 1.32% (n=11) is obtained. As a comparison, the time-dependent injection was tested using the same chip which resulted in an inferior repeatability.Type: GrantFiled: October 6, 2017Date of Patent: December 28, 2021Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Noel Seunghyun Ha, R. Michael Van Dam, Jimmy Ly
