Publication number: 20160161479Abstract: The invention relates to optoelectronic systems for detecting one or more target particles. The system includes a reaction chamber, a specimen collector, an optical detector, and a reservoir containing cells, each of the cells having receptors which are present on the surface of each cell and are specific for the target particle to be detected, where binding of the target particle to the receptors directly or indirectly activates a reporter molecule, thereby producing a measurable optical signal.Type: ApplicationFiled: November 11, 2014Publication date: June 9, 2016Inventors: James Douglas Harper, Richard Hart Mathews, Bernadette Johnson, Martha Susan Petrovick, Ann Rundell, Frances Ellen Nargi, Timothy Stephens, Linda Marie Mendenhall, Mark Alexander Hollis, Albert M. Young, Todd H. Rider, Eric David Schwoebel, Trina Rae Vian

Patent number: 8171695Abstract: A structural member and method with an improved arm connection is provided that allows quick connection of an arm to the structural member. Pins are inserted through aligned apertures in first and second thru-vangs, as well as an abutting arm bracket. A flexible securement member is inserted through an aperture in the pins that is transverse to the pins. Last, an arm is secured to the arm bracket for support of electrical conductors strung thereon.Type: GrantFiled: March 30, 2010Date of Patent: May 8, 2012Assignee: Thomas & Butts International, Inc.Inventors: Aubrey Jackson, David Nahlen, Jim Palmer, Timothy Stephens

Patent number: 4777426Abstract: The aerodynamic window of the present invention provides a barrier between two different environments of a high energy laser device. The first environment is a transverse gas flow across the laser beam and the third environment is an axial flow beam path. The window having a second environment therein changes both the gas temperature and the gas pressure along the laser beam to minimize optical path differences between the first and third environments. The second environment has a thermal transition section and an injection section. In the thermal transition section before the injection section, a gas manifold provides a varying gas flow field. The thermal transition section changes the gas temperature while maintaining its pressure and velocity constant. A transverse flow is exhausted in a location opposite to the gas manifold. The axial flow enters into the injection section. Gas ejectors in the injection section mix the axial flowing gas and increase the gas pressure and velocity.Type: GrantFiled: March 6, 1987Date of Patent: October 11, 1988Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Timothy Stephens
