US Patent:

59447486, Aug 31, 1999

Filed:

Jul 25, 1997

Appl. No.:

8/900975

Inventors:

David Mager - Leverett MA
Harvey I. Pass - Novi MI
Melvin Tecotzky - Mendham NJ

Assignee:

Light Medicine, Inc. - Leverett MA

International Classification:

A61B 1736

US Classification:

607 88

Abstract:

A device for applying light in photodynamic therapy is arranged to apply light in a pattern corresponding to the configuration of the lesion to be treated. The device may be customized in response to an image of the patient acquired before treatment. Alternatively, the device may include sensors for detecting a characteristic of tissue overlying each region of the device so that the device either emits light or does not emit light in each region depending upon the characteristics of the overlying tissue.

Abstract:

An integrated system for converting ocean thermal energy to electrical power for use in synthesis of anhydrous ammonia and a mariculture operation for raising a selected species of marine fauna. The mariculture operation is carried out in a lagoon located adjacent to a deep ocean region where the surface water temperature is at least 21. degree. C and the deep nutrient-rich water temperature is no more than about 10. degree. C. A separate working fluid, such as ammonia, operates in a Rankine cycle between the warm and cold seawater temperatures. The deep ocean water is used to condense the working fluid and is then mixed with warm surface water that has been used to evaporate the same working fluid in a closed power cycle. The resulting mixture is directed to the lagoon, where the nutrient-rich component contributes to the growth rate of a selected mariculture species. The warm surface water temperature may be increased by creating a monomolecular evaporation retarding layer in the ocean surface surrounding the power plant intake.
