Patent number: 11142732Abstract: Method and apparatus for biomass cultivation (preferably using algae) incorporating photo bio-reactor (PBR) technology coupled with a heat sink to increase energy efficiency. An external PBR array is coupled to an indoor storage tank system with a volume equal to or greater than the volume of the PBR array. A controller can be used to optimize the growth of biomass by optimizing three key growth parameters: exposure to sunlight, temperature and nutrients. The indoor tank system serves as a reservoir where algae can be protected from harsh ambient conditions, minimizing the cost of energy for heating and cooling that would normally be incurred to accommodate ambient temperature swings caused by weather if the biomass is always stored in an outdoor PBR array. During cold winter nights, the biomass can be brought indoors to conserve thermal energy.Type: GrantFiled: October 22, 2019Date of Patent: October 12, 2021Assignee: NSE, Inc.Inventors: Luke Spangenburg, Charles J.

Patent number: 11130127Abstract: Provided herein are devices and methods of processing a sample that include, in several embodiments, rotating one or more microfluidic chips that are mounted on a support plate using a motor driven rotational chuck. By spinning one or more of the microfluidic chips about a common center of rotation in a controlled manner, high flow rates (and high shear forces) are imparted to the sample in a controlled manner. Each microfluidic chip can be rotated 180° on the support plate so that the sample can be run back-and-forth through the microfluidic devices. Because the support plate can be driven at relatively high RPMs, high flow rates are generated within the microfluidic chips. This increases the shear forces on the sample and also decreases the processing time involved as the sample can quickly pass through the shear-inducing features of the microfluidic chip(s).Type: GrantFiled: January 30, 2020Date of Patent: September 28, 2021Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Ahmed Zobi, Justin Stovner, Hugo Salas, David Duarte, Jered Haun, Alan Widgerow, Derek Banyard
