Patent number: 11885372Abstract: The present disclosure relates to a reduced friction torsion component system that makes use of a first frame portion adapted to be coupled to, or integrally formed with, a first object, and forming a first bore, and a second frame portion adapted to be coupled to, or integrally formed with, a second object, and forming a second bore. The two bores are axially aligned and receive at least one elongated hinge component. The elongated hinge component operates to both couple the first and second frame portions together for pivoting movement relative to one another, and also provides a torsional biasing force to enable pivotal deployment from a first position to a second position of one of the first or second frame portions.Type: GrantFiled: July 13, 2020Date of Patent: January 30, 2024Assignee: Lawrence Livermore National Security, LLCInventors: Vincent Riot, Darrell Carter, Todd Alan Decker

Patent number: 9156010Abstract: Systems, including apparatus and methods, for performing assays. These systems may involve separating sample components by partitioning them into droplets or other partitions, amplifying or otherwise reacting the components within the droplets, detecting the amplified components, or characteristics thereof, and/or analyzing the resulting data, among others.Type: GrantFiled: September 23, 2009Date of Patent: October 13, 2015Assignee: Bio-Rad Laboratories, Inc.Inventors: Billy Wayne Colston, Jr., Benjamin Joseph Hindson, Kevin Dean Ness, Donald Arthur Masquelier, Fred Paul Milanovich, Douglas N.

Patent number: 8065119Abstract: A computerized method and system for designing an aerodynamic focusing lens stack, using input from a designer related to, for example, particle size range to be considered, characteristics of the gas to be flowed through the system, the upstream temperature and pressure at the top of a first focusing lens, the flow rate through the aerodynamic focusing lens stack equivalent at atmosphere pressure; and a Stokes number range. Based on the design parameters, the method and system determines the total number of focusing lenses and their respective orifice diameters required to focus the particle size range to be considered, by first calculating for the orifice diameter of the first focusing lens in the Stokes formula, and then using that value to determine, in iterative fashion, intermediate flow values which are themselves used to determine the orifice diameters of each succeeding focusing lens in the stack design, with the results being output to a designer.Type: GrantFiled: March 20, 2008Date of Patent: November 22, 2011Assignee: Lawrence Livermore National Security, LLCInventors: Eric Gard, Vincent Riot, Keith Coffee, Bruce Woods, Herbert Tobias, Jim Birch, Todd Weisgraber

Patent number: 7361891Abstract: A pressure-flow reducer, and an aerosol focusing system incorporating such a pressure-flow reducer, for performing high-flow, atmosphere-pressure sampling while delivering a tightly focused particle beam in vacuum via an aerodynamic focusing lens stack. The pressure-flow reducer has an inlet nozzle for adjusting the sampling flow rate, a pressure-flow reduction region with a skimmer and pumping ports for reducing the pressure and flow to enable interfacing with low pressure, low flow aerosol focusing devices, and a relaxation chamber for slowing or stopping aerosol particles. In this manner, the pressure-flow reducer decouples pressure from flow, and enables aerosol sampling at atmospheric pressure and at rates greater than 1 liter per minute.Type: GrantFiled: June 19, 2006Date of Patent: April 22, 2008Assignee: Lawrence Livermore National Security, LLCInventors: Eric Gard, Vincent Riot, Keith Coffee, Bruce Woods, Herbert Tobias, Jim Birch, Todd Weisgraber

Publication number: 20050073683Abstract: An improved method and system of identifying individual aerosol particles in real time. Sample aerosol particles are collimated, tracked, and screened to determine which ones qualify for mass spectrometric analysis based on predetermined qualification or selection criteria. Screening techniques include one or more of determining particle size, shape, symmetry, and fluorescence. Only qualifying particles passing all screening criteria are subject to desorption/ionization and single particle mass spectrometry to produce corresponding test spectra, which is used to determine the identities of each of the qualifying aerosol particles by comparing the test spectra against predetermined spectra for known particle types. In this manner, activation cycling of a particle ablation laser of a single particle mass spectrometer is reduced.Type: ApplicationFiled: August 11, 2004Publication date: April 7, 2005Inventors: Eric Gard, Keith Coffee, Matthias Frank, Herbert Tobias, David Fergenson, Norm Madden, Vincent Riot, Paul Steele, Bruce Woods

Publication number: 20050023477Abstract: A portable radioactive-material detection system capable of detecting radioactive sources moving at high speeds. The system has at least one radiation detector capable of detecting gamma-radiation and coupled to an MCA capable of collecting spectral data in very small time bins of less than about 150 msec. A computer processor is connected to the MCA for determining from the spectral data if a triggering event has occurred. Spectral data is stored on a data storage device, and a power source supplies power to the detection system. Various configurations of the detection system may be adaptably arranged for various radiation detection scenarios. In a preferred embodiment, the computer processor operates as a server which receives spectral data from other networked detection systems, and communicates the collected data to a central data reporting system.Type: ApplicationFiled: June 21, 2004Publication date: February 3, 2005Inventors: Daniel Archer, Brock Beauchamp, G.
