Abstract

The use of magnetic fields in the production of porous articles is generally described. Certain embodiments comprise exposing a matrix to a magnetic field such that particles within the matrix form one or more elongated regions (e.g., one or more regions in which the particles chain). In some embodiments, after the magnetic field has been applied, the particles and/or a liquid within the matrix can be at least partially removed. Removal of the particles and/or the liquid can leave behind anisotropic pores within the remainder of the matrix material.

Methods for controlling pore morphology in aerogels using electric fields and products thereof

Patent Worsley, Marcus A.; Baumann, Theodore F.; Satcher, Jr., Joe H.; ...

In one embodiment, an aerogel or xerogel includes column structures of a material having minor pores therein and major pores devoid of the material positioned between the column structures, where longitudinal axes of the major pores are substantially parallel to one another. In another embodiment, a method includes heating a sol including aerogel or xerogel precursor materials to cause gelation thereof to form an aerogel or xerogel and exposing the heated sol to an electric field, wherein the electric field causes orientation of a microstructure of the sol during gelation, which is retained by the aerogel or xerogel.

System and method using hybrid magnetic field model for imaging magnetic field sources

Patent Derego, Paul Jeffrey

A system and method for detecting a magnetic field generated by a magnetic field source located in a circuit. A magnetometer array generates data regarding an activity of the source. A computing device executes a magnetic beamforming data processing program including a hybrid model which receives data generated by the array and detects the magnetic field generated by the source. The hybrid model is based on a weighted sum of contributions to the magnetic field, which include a first modelled magnetic field contribution generated by a current dipole aligned with an axis of the source, and a second modelled magneticmore » « less

High speed flux feedback for tuning a universal field oriented controller capable of operating in direct and indirect field orientation modes

Patent De Doncker, Rik W. A. A. (Schenectady, NY)

The direct (d) and quadrature (q) components of flux, as sensed by flux sensors or determined from voltage and current measurements in a direct field orientation scheme, are processed rapidly and accurately to provide flux amplitude and angular position values for use by the vector rotator of a universal field-oriented (UFO) controller. Flux amplitude (linear or squared) is provided as feedback to tune the UFO controller for operation in direct and indirect field orientation modes and enables smooth transitions from one mode to the other.

System and method for measuring fluid properties using magnetic field techniques via magnetic tracer

Patent Mazumdar, Yi Chen; Nemer, Martin B.; Brooks, Carlton F.; ...

A method and apparatus for determining a property of a fluid in a vessel. The method uses magnetic tracer particles and an externally applied magnetic field which orients the particles. When the fluid moves, it changes the orientation of the tracer particles, thus changing the magnetic fields. These changes are detected by external magnetic field sensors. By using mathematical models, the property of the fluid in the vessel is determined from the detected magnetic field. In this manner, fluid vorticity, velocity, strain and stress may be estimated.

Steel characteristics measurement system using Barkhausen jump sum rate and magnetic field intensity and method of using same

Patent Kohn, Gabriel [Omer, IL]; Hicho, George [Derwood, MD]; Swartzendruber, Lydon [New Carrollton, MD]

A steel hardness measurement system and method of using same are provided for measuring at least one mechanical or magnetic characteristic of a ferromagnetic sample as a function of at least one magnetic characteristic of the sample. A magnetic field generator subjects the sample to a variable external magnetic field. The magnetic field intensity of the magnetic field generated by the magnetic field generating means is measured and a signal sensor is provided for measuring Barkhausen signals from the sample when the sample is subjected to the external magnetic field. A signal processing unit calculates a jump sum rate firstmore » « less
