US Classification:

435/006000, 435/287200, 435/286500

Abstract:

Methods and apparatus for promoting interactions between an array of probes deposited on a microarray substrate and target molecules in a target liquid are provided. A microarray apparatus can include a substrate having an array of probes deposited on a surface of the substrate for interaction with a target molecule in a target liquid. The apparatus also includes a cover coupled to the substrate to form a reaction chamber therebetween, wherein the array of probes is contained within the reaction chamber and the substrate and the cover are movable relative to each other.

International Classification:

A61M 16/00

US Classification:

12820715

Abstract:

The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

Filed:

Feb 26, 1993

Appl. No.:

8/023502

Inventors:

Peter G. Borden - San Mateo CA
Hoang K. Nguyen - Austin TX
Earl J. Carrasco - Fremont CA

Assignee:

High Yield Technology - Sunnyvale CA

International Classification:

G01N 1506

US Classification:

250573

Abstract:

A structure and an apparatus are provided for use in particle sensor installed to monitor particle level of a process chamber. The process chamber receives process gas from a supply line and removes gas through an exhaust line. The particle sensor's optical components are prevented from contamination by corrosive or coating species in the effluent from the process, by a gas purge line installed in the particle sensor. The gas purge line allows a flow of gas to purge the optical components at a flux not less than the flux of gas being removed from the process chamber in the exhaust line. The flux out of the particle sensor prevents the undesired species from reaching the optical components of the particle sensor from the sampling area where the particle sensor detects the particle level.

Assignee:

The Regents of the University of California - Oakland CA

International Classification:

B23K 2638

US Classification:

21912172

Abstract:

A method and apparatus for improving the quality and efficiency of machining of materials with laser pulse durations shorter than 100 picoseconds by orienting and maintaining the polarization of the laser light such that the electric field vector is perpendicular relative to the edges of the material being processed. Its use is any machining operation requiring remote delivery and/or high precision with minimal collateral dames.
