Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G01N 27/26
G01N 33/00

US Classification:

250306, 250307, 204400, 977762, 977957

Abstract:

A sensing method includes exposing a nano-transducer having a controlled surface to a sample including at least one species. Adsorption of the species on the nano-transducer is transduced to a measurable signal as a function of time. Desorption of the species from the nano-transducer is also transduced to a measurable signal as a function of time. A residence time of the at least one species adsorbed on the nano-transducer is extracted from the measurable signals. The adsorption and desorption each define an individual measurable event.

Appl. No.:

6/411060

Kenneth R. Ward - San Jose CA

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

B23K 2700

US Classification:

219121FS

Abstract:

An apparatus provides to a surface a laser beam and gas stream that impinge and rotate in coincidence. The apparatus comprises an optical system (11) to direct the laser beam to a spot in a plane and a stationary gas plenum (16) through which gas passes en route to an outlet nozzle (18) that directs the gas stream to the same spot. The optical system and nozzle rotate in synchronism to cause the spot to trace a circle. The apparatus finds application in materials processing, such as welding and cutting (trepanning).

International Classification:

G01N 21/65

Abstract:

Optical readers are disclosed in examples herein. An example optical reader including a light source to emit a light beam; and a spot pattern generator to receive the light beam and to generate a two-dimensional spot array from the light beam, the two-dimensional spot array to be directed toward a substrate having nanostructures, the two-dimensional spot array to be sensed to detect a presence or an absence of a substance of interest on the substrate.
