Patent number: 10730050Abstract: The combined value of integrating optical forces and electrokinetics allows for the pooled separation vectors of each to be applied, providing for separation based on combinations of features such as size, shape, refractive index, charge, charge distribution, charge mobility, permittivity, and deformability. The interplay of these separation vectors allow for the selective manipulation of analytes with a finer degree of variation. Embodiments include methods of method of separating particles in a microfluidic channel using a device comprising a microfluidic channel, a source of laser light focused by an optic into the microfluidic channel, and a source of electrical field operationally connected to the microfluidic channel via electrodes so that the laser light and the electrical field to act jointly on the particles in the microfluidic channel. Other devices and methods are disclosed.Type: GrantFiled: May 23, 2018Date of Patent: August 4, 2020Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Sean J. Hart, Sarah J. R. Staton, Alexander V. Terray, Gregory E. Collins

Patent number: 5820066Abstract: Methods and apparatus for laying fluid distribution lines along a surface are disclosed. An overhead support cable is secured between a plurality of anchoring devices spaced along the surface. A rotatable installation reel is then coupled to the overhead support cable and a coil of fluid distribution line is loaded on the installation reel. Fluid distribution line is laid along the surface by moving the installation reel along the overhead support cable so as to rotate the installation reel to pay out the fluid distribution line along the surface. Subsequent fluid distribution lines may be laid at substantially equal lateral spacings by moving each anchoring device or a portion of each anchoring device prior to laying each subsequent fluid distribution line.Type: GrantFiled: May 16, 1997Date of Patent: October 13, 1998Assignee: Phelps Dodge CorporationInventors: Ramon G.

Patent number: 5719061Abstract: A method and apparatus for the detection of hydrazine, monomethylhydrazine, 1,1-dimethylhydrazine in air (or other gas medium) or in an aqueous solution. The detection is accomplished by introducing a stream of air, or other gas medium, or aqueous solution suspected of containing hydrazine, monomethylhydrazine, 1,1-dimethylhydrazine or mixtures thereof into a pH controlled reagent solution containing an aromatic dicarboxaldehyde to react with the hydrazine, monomethylhydrazine, 1,1-dimethylhydrazine or mixtures thereof, respectively, and by exposing the reacted reagent solution to an excitation wavelength range and monitoring an emission from the exposed reagent solution at an emission wavelength range to detect the presence of a hydrazine derivative, monomethylhydrazine derivative, 1,1-dimethylhydrazine derivative, or mixtures thereof (i.e.Type: GrantFiled: October 20, 1994Date of Patent: February 17, 1998Assignee: The United States of America as represented by the Secretary of the NavyInventors: Susan Rose-Pehrsson, Gregory E.
