Full Record
Other Related Research

Abstract

A broadband downhole logging device includes a double-helix coil wrapped over a dielectric support and surrounded by a dielectric shield. The device may also include a second coil longitudinally aligned with a first coil and enclosed within the same shield for measuring magnetic permeability of downhole formations and six additional coils for accurately determining downhole parameters.

Dual excitation acoustic paramagnetic logging tool

Patent Vail, III, William B. (Bothell, WA)

New methods and apparatus are disclosed which allow measurement of the presence of oil and water in gelogical formations using a new physical effect called the Acoustic Paramagnetic Logging Effect (APLE). The presence of petroleum in formation causes a slight increase in the earth's magnetic field in the vicinity of the reservoir. This is the phenomena of paramagnetism. Application of an acoustic source to a geological formation at the Larmor frequency of the nucleous present causes the paramagnetism of the formation to disappear. This results in a decrease in the earth's magnetic field in the vicinity of the oil bearingmore » « less

Portable dual field gradient force multichannel flow cytometer device with a dual wavelength low noise detection scheme

Patent James, Conrad D; Galambos, Paul C; Derzon, Mark S; ...

Systems and methods for combining dielectrophoresis, magnetic forces, and hydrodynamic forces to manipulate particles in channels formed on top of an electrode substrate are discussed. A magnet placed in contact under the electrode substrate while particles are flowing within the channel above the electrode substrate allows these three forces to be balanced when the system is in operation. An optical detection scheme using near-confocal microscopy for simultaneously detecting two wavelengths of light emitted from the flowing particles is also discussed.

Helical antenna and method of modulating the performance of a wireless communications device

Patent Li, Xiuling; Huang, Wen; Froeter, Paul J.

A wireless communication device includes an array of helical antennas on a substrate. Each helical antenna comprises a strain-relieved sheet with a conductive strip thereon, where the strain-relieved sheet and the conductive strip are in a rolled configuration about a longitudinal axis. The conductive strip is oriented at an angle α with respect to a rolling direction so as to comprise a helical configuration about the longitudinal axis with a non-zero helix angle β. The array exhibits a maximum gain of at least about 10 dB at a working frequency of at least about 0.1 THz.
