Filed:

Apr 13, 2001

Appl. No.:

09/835053

Inventors:

Tracy Brewer - Hayward CA
Marlon Geronimo - Union City CA
Charles Chan - Fremont CA
Sam Chan - San Jose CA

Assignee:

Wavesplitter Technologies, Inc. - Fremont CA

International Classification:

G02B 600

US Classification:

385147, 81 941, 81 951, 30 901

Abstract:

A method and apparatus is described for stripping the coating of an optical fiber. A fixture having a fiber cleat may be used to secure an optical fiber to enable removal of the protective coating from the fiber along a precise length of the fiber. The length of protective coating removal may be controlled by a strip guide. A stop coupled to the apparatus also controls how much of the coating is removed.

Appl. No.:

9/158326

Inventors:

Joseph A. Slater - San Jose CA
Sam Chan - San Jose CA

Assignee:

Glaxo Wellcome Inc. - Research Triangle Park NC

International Classification:

G01F 1100

US Classification:

222 1

Abstract:

The invention provides systems, methods, and apparatus for dispensing liquids. According to one method, a plate is provided having a plurality of wells. At least one marker is also provided and is associated with at least some of the wells. The plate and marker are moved relative to a plurality of liquid dispensing elements, and the presence of the marker is sensed with a sensor that is disposed at a known location relative to the dispensing elements. The sensing of the marker indicates that at least some of the wells are aligned with the dispensing elements. As such, liquid is dispensed from the dispensing elements and into the aligned wells after sensing the presence of the marker.

International Classification:

G01N 2103
G01N 3300

US Classification:

436178

Abstract:

The invention provides exemplary systems, methods, and apparatus for distinctly allocating liquids containing chemical compositions or compounds to known locations in an organized manner so that assays may be performed on the compositions, or so that the chemical compositions may be combined with other distinct chemical compositions or reagents prior to evaluation. In an exemplary embodiment, the invention includes a multiwell plate for handling articles such as resin beads suspended in a liquid. The plate comprises a plurality of wells. The wells in turn have a capillary hole that is adapted to (i) retain articles in the well, and (ii) retain liquid in the well while the liquid is not subjected to extrinsic forces, such as centrifugation or vacuum.

Assignee:

Glaxo Wellcome Inc. - Research Triangle Park NC

International Classification:

G01N 33551

US Classification:

422 99

Abstract:

The invention provides systems and methods for processing a plurality of solid supports which preferably have chemical compounds synthesized thereon. According to one exemplary method, the solid supports (12) are held in a common storage location (10). At least some of the solid supports (24) are attracted from the storage location to selected areas within a defined receiving region (20) so that the solid supports which are attracted to the selected areas within the receiving region are separated and spaced apart from each other.
