Publication number: 20240136983Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.Type: ApplicationFiled: October 24, 2023Publication date: April 25, 2024Inventors: Dan William Nobbe, David Halchin, Jeffrey A. Dykstra, Michael P. Gaynor, David Kovac, Kelly Michael Mekechuk, Gary Frederick Kaatz, Chris Olson

Publication number: 20220002357Abstract: Disclosed herein is a G protein-coupled receptor (GPCR) assay platform comprised of two complementary systems that equate dynamic intermolecular interactions between a receptor and transducer with more complex stimulus-response cascades in living cells. In the disclosed in vitro ADSoRB method, the forced dissociation of transducers like G protein heterotrimers from receptors alters receptor conformations and ligand interactions to simulate pathway activation in a cell. In the disclosed TRUPATH method, measuring the extent of engineered G protein heterotrimer complex dissociation provides single transducer resolution in a cell.Type: ApplicationFiled: December 3, 2019Publication date: January 6, 2022Inventors: Ryan Strachan, Reid Olsen, Bryan Leo Roth, Justin Gregory English, Jeffrey Frederick Diberto
