International Classification:

F28D 11/06

F28D 15/00

US Classification:

165 84, 239706, 239695, 16510421

Abstract:

Electrospray evaporative cooling (ESC). Means for effectuating thermal management using electrospray cooling are presented herein. An ESC may be implemented having one or more nozzles situated to spray droplets of a fluid towards a target. Because the fluid may be electrolytic, an electric field may be established between the one or more nozzles and the target can be operative to govern the direction, rate, etc. of the electrospraying between the one or more nozzles and the target. An additional shielding/field enhancement electrode may also be implemented between the one or more nozzles and the target. A droplet movement mechanism may be employed to transport droplets received at a first location of the target so that evaporation thereof may occur relatively more at a second location of the target. An ESC device may be implemented to effectuate thermal management of any of a variety of types of electronic devices.

G01R 27/26
G01R 33/16

US Classification:

702 65, 324201, 174 34, 324684

Abstract:

Systems and methods are provided for remotely identifying and classifying materials based on their respective complex permittivity features. Materials of interest to be identified in later inspections are cataloged according to their respective complex permittivity features by applying electromagnetic fields to them and determining their complex permittivity features. That library of features is used to compare field measurements taken during an inspection to determine the presence of a material of interest and to identify it.

US Patent:

Filed:

Sep 11, 2015

Appl. No.:

14/851492

Inventors:

- Seattle WA, US
Alexander V. Mamishev - Seattle WA, US

International Classification:

B03C 3/45

Abstract:

An electrostatic precipitator may have different collecting and repelling electrodes surfaces. For example, a collecting electrode may have an internal conductive portion. A non-conductive or less conductive open cell foam covering may be applied to the conductive core of the collecting electrode. The foam may have cell sizes that vary within the volume of the foam or along the length of the foam. Accordingly the cell size of the foam near the leading, with respect to the direction of airflow, portion of the collector may be larger than the cell size of the foam nearer the trailing end of the collector and/or the cell size of the foam near the exterior of the collector may be larger than the cell size of the foam nearer to the interior of the collector.

Appl. No.:

14/851510

Inventors:

- Seattle WA, US
Alexander V. Mamishev - Seattle WA, US

International Classification:

B03C 3/45

Abstract:

An electrostatic precipitator may have a set of collector electrodes and a set of repelling electrodes. The conductive portions of the collector electrodes and/or the repelling may be arranged in segments. The segments may have differing electrical properties or may be electrically isolated to facilitate differing potentials along an airflow path. The differing potentials results in differing electric field strengths along the airflow path.

Inventors:

- Seattle WA, US
Alexander V. Mamishev - Seattle WA, US

International Classification:

B03C 3/45

Abstract:

An electrostatic precipitator is constructed with collecting and repelling electrodes. The collecting electrode is partially shielded from gas shear forces by a shielding structure. The shielding structure is mounted to reduce gas flow along a surface of the collector and includes passages for charged particles to travel to be captured by the collector.
