Filed:

Feb 5, 2009

Appl. No.:

12/365901

Inventors:

Chien NGUYEN - Huntigton Beach CA, US
Ekrem CENGELCI - Garden Grove CA, US
Michael TRAN - Winnetka CA, US

Assignee:

MICROSEMI CORPORATION - Garden Grove CA

International Classification:

H05B 37/00

US Classification:

315122

Abstract:

A solid state lighting unit constituted of: a control circuitry; a single string of light emitting diodes, the single string constituted of a plurality of sections each comprising a plurality of light emitting diodes; and a plurality of bypass paths each responsive to the control circuitry, each of the plurality of bypass paths arranged to provide bypass to a particular one of the plurality of sections, wherein the control circuitry is operative to identify an open circuit condition of a particular one of the plurality of sections, and activate the bypass path arranged to bypass the open circuit section, thereby providing light through sections not exhibiting an open circuit condition.

Appl. No.:

9/133928

Inventors:

Richard P. Watts - Diamond Bar CA
David L. Goodale - Yorba Linda CA
Michael L. Bell - Fullerton CA
Dang M. Ngo - Fountain Valley CA
Songai Tu - Yorba Linda CA
Michael Tran - Aliso Viejo CA

Assignee:

Beckman Instruments, Inc. - Fullerton CA

International Classification:

G01N35/00

US Classification:

422 63

Abstract:

An automatic chemistry analyzer is provided having a high throughput and a high reliability. The analyzer uses nephelometric and turbimetric analyzers to analyze a wide variety of parameters within liquid samples typically generated in, for example, a large medical testing laboratory. The machine employs a unique probe and stirring rod assembly mounted at a slight angle with one another using rack and pinion assemblies so that the lower end of the probe and the lower end of the stirring rod are in very close proximity to one another. This feature allows the machine to be used in unusually small reaction cuvettes. The analysis machine also includes an onboard control sample so that the machine can be programmed to periodically calibrate its analyzing equipment during the course of normal operation. The machine also includes a sample station carousel having retainer clips for retaining a sample container rack which is constructed to retain a bar-coded card containing information regarding reagents used in the machine. A bar code reader located proximate to the sample carousel reads the bar-coded reagent information into the controller.
