Appl. No.:

09/252386

Inventors:

Osman Saim Dinc - Troy NY
Kenneth Roger Conway - Troy NY
Onika Misasha Kerber - Greenville SC

Assignee:

General Electric Company - Niskayuna NY

International Classification:

G01M 332

US Classification:

73 52

Abstract:

One method empirically determines a stiffness value for each of two or more different subsets of the bristles of a brush seal, then calculates a variation in stiffness, and then identifies the brush seal as defective if the calculated variation in stiffness exceeds a predetermined stiffness variation criteria. One apparatus includes a load transducer having a contact head sized to contact less than twenty percent of the bristles, a displacement transducer which measures the displacement of the free ends of the contacted bristles, and a clamp for securing the brush seal and presenting the bristles for contact.

International Classification:

H01L 29/06

US Classification:

257 17, 257 14, 257 22

Abstract:

The present invention is directed toward a method for fabricating low-defect nanostructures of wide bandgap materials and to optoelectronic devices, such as light emitting sources and lasers, based on them. The invention utilizes nanolithographically-defined templates to form nanostructures of wide bandgap materials that are energetically unfavorable for dislocation formation. In particular, this invention provides a method for the fabrication of phosphor-less monolithic white light emitting diodes and laser diodes that can be used for general illumination and other applications.

International Classification:

C12M 1/42

US Classification:

4352891

Abstract:

A system for delivering exogenous molecules comprises a support for containing cells and exogenous molecules; an infra-red (IR) light source that generates an IR optical beam with an average power density at least greater than 10W/cm; one or more optical elements; an imaging system to image the cells in a field of view; a processor that generates a signal for localization of cells in the field of view; a light pattern shaper for temporal focusing of optical beam to generate wide field illumination on the cells to permeabilise the cell membrane for delivering the exogenous molecules; and a controller that switches optical beam from wide field illumination to a focused illumination. The processor is operatively coupled to the imaging system and the light pattern shaper and transmits the signal for the localization of cells to ensure the temporal focusing of the optical beam on the cells.

Abstract:

Methods for treatment of sludge with microwave irradiation for improving its dewatering are provided. In one embodiment, the method includes exposing the sludge to microwave irradiation at a power density of between about 3 W/ml and about 17 W/ml. Turbidity, total solids content and overall dewaterability are improved when the microwave irradiation treatment is combined with another method for dewatering sludge, such as enzyme treatment, conditioning with a flocculating agent and mechanical dewatering.
