US Patent:

6564224, May 13, 2003

Filed:

Mar 30, 2000

Appl. No.:

09/539721

Inventors:

Xiaoyi Wu - Fremont CA
W. Clayton Collier - San Ramon CA
Rajiv K. Synghal - Concord CA
James Whitaker - Livermore CA

Assignee:

Kivera, Inc. - Oakland CA

International Classification:

G06F 1730

US Classification:

7071041

Abstract:

A method and apparatus for combining two dissimilar road map databases of a given geographic region are provided. The road map database differ in degree of coverage or accuracy of coverage, or both, of the geographic region. Each database includes data defining a plurality of roads. A first set of loops is defined from roads represented in a first of the two road map databases. For each of the first set of loops, a corresponding loop is identified from roads represented in a second of the two road map databases, to define a second set of loops. Each loop of the second set of loops may include one or more links, and each link represents a portion of a road represented in the second road map database. A set of output loops corresponding to the first set of loops is generated to form an output road map database. Links enclosed within loops of the second set of loops and not represented in the first road map database are then copied into the set of output loops, such that the output road map database represents a combination of the first road map database and the second road map database.

Appl. No.:

12/723089

Inventors:

Robert R. Kerr - Cupertino CA, US
James D. Whitaker - Santa Clara CA, US

Assignee:

Terrasep, LLC - Mountain View CA

International Classification:

B01D 15/08

US Classification:

2101982, 210657

Abstract:

Apparatus and methods related to centrifugal liquid chromatography are described. An angular velocity can be simultaneously imparted to a large number of chromatographic enclosures. Via centrifugal forces, a mobile phase fluid including a sample can be driven through a stationary phase within the chromatographic enclosure to perform a chromatographic separation process on components of the sample. The use of centrifugation as a driving force can allow significantly smaller stationary phase particles to be employed as compared to high performance liquid chromatography (HPLC). Further, for an equivalent chromatographic separation process, the use of centrifugation can provide much greater separation efficiencies than HPLC.
