Filed:

Aug 5, 2002

Appl. No.:

10/213122

Inventors:

John R. Hurst - San Diego CA

Assignee:

ChemNavigator, Inc. - San Diego CA

International Classification:

G01N 3100

US Classification:

702 27, 703 11

Abstract:

Methods which may be implemented in computer systems for screening a database of candidate molecules to determine whether any particular subset of candidate molecules may be docked to a target molecule. These methods determine the force field of a target molecule only once and may be used for screening a large number of candidate molecules.

Assignee:

Arena Pharmaceuticals, Inc. - San Diego CA

International Classification:

G06F 700

US Classification:

707102, 702 19, 702 27

Abstract:

Disclosed herein are systems and methods for information organization whereby characteristics regarding entities are inferred from the characteristics of similar entities. This is referred to herein as a âfuzzy similarity joinâ and is exemplified using a chemical similarity join. The disclosed systems and methods are particularly useful for chemical compound analysis in the area of pharmaceutical development.

International Classification:

C02F 1/00
C02F 1/28

US Classification:

210164, 2105021, 210691, 405 40, 405127, 404 4

Abstract:

A storm drain filter including a frame holding a filter assembly to filter incoming drainage water and thereby prevent sediment from entering the storm drain's inlet. The frame can be easily removed and replaced to allow street sweeping. In one embodiment, an erosion control apparatus comprises one or more broom filters each including a plurality of adjacent bristles, and a frame that holds the broom filter(s) so that the bristles extend downwardly to the road surface. In one embodiment, the beam of the broom filter is pivotally connected to the frame, and the bristles have substantially greater than a 90 vertical angle, to allow the weight and flexibility of the bristles to conform to variations in the road surface. A filtration bag to filter hydrocarbons may be attached downstream of the broom filter. The frame can be designed for a wide variety of implementations, and can be re-usable.

Appl. No.:

11/343150

Inventors:

John G. Hurst - Encinitas CA, US

International Classification:

E03F 5/14

US Classification:

210163, 210164, 210348, 210359, 404 4

Abstract:

A storm drain filter assembly that filters incoming drainage water and can prevent sediment, debris, and other undesirable materials (such as oil) from entering a storm drain's inlet. The frame can be rotated upwardly away from the road for street sweeping, and can also be detached from the curb and removed to a remote location for cleaning. The filter assembly comprises a filter panel including a bristle filter and a frame that holds the bristle filter, the bristle filter including a plurality of bristles. At least one seal is positioned between the filter panel and the surface to prevent leakage around the edges of the panel. A pivotable mount is provided for holding the filter panel in an operational position in the path of the flowing drainage water. In one embodiment the bristles are made of polypropylene.
