Filed:

Aug 27, 2008

Appl. No.:

12/199619

Inventors:

Amit A. Kulkarni - Highland Village TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

F21V 29/00

US Classification:

362294, 362373, 362218

Abstract:

According to certain embodiments, an apparatus for cooling light emitting diodes (LEDs) in projectors includes one or more first LEDs, one or more first heat sinks, one or more second LEDs, and one or more second heat sinks. The first LEDs are configured to generate light, and each first LED has a first desired junction temperature. The first heat sinks are configured to dissipate heat generated by the first LEDs. The second LEDs are configured to generate light, and each second LED has a second desired junction temperature that is higher than the first desired junction temperature. The second heat sinks are configured to dissipate heat generated by the one or more second LEDs. A cooling fan directs air flow over the first heat sinks and the second heat sinks, and an exhaust vent enables the air flow over the first heat sinks and the second heat sinks.

Appl. No.:

09/865090

Inventors:

Harold Garner - Flower Mound TX, US
Amit Kulkarni - Dallas TX, US

International Classification:

G06F007/00

US Classification:

707/003000

Abstract:

The invention relates to computer-based systems and methods for the design, comparison and analysis of genetic and proteomic databases. In a particular embodiment, the recited systems and methods have been implemented in a computer tool called ARROGANT. ARROGANT, in the analysis mode, is a comprehensive tool for providing annotation to large gene and protein collections. ARROGANT takes in a large collection of sequence identifiers and associates it with other information collected from many sources like sequence annotations, pathways, homology, polymorphisms, artifacts, etc. The simultaneous annotation for a large assembly of genes makes the collection of genomic/EST sequences truly informative.
