Filed:

Apr 17, 2003

Appl. No.:

10/418712

Inventors:

Jane Chen - Diamond Bar CA, US
Yongqiang Shi - Diamond Bar CA, US

Assignee:

General Photonics Corporation - Chino CA

International Classification:

G02F 1/09
G02B 5/30

US Classification:

359281, 359495, 359497, 385 11, 385 32

Abstract:

Techniques and devices for depolarizing light and producing a variable differential group delays in optical signals. In one implementation, an input optical beam is split into first and second beams with orthogonal polarizations. One or two optical reflectors are then used to cause the first and second optical beams to undergo different optical path lengths before they are recombined into a single output beam. An adjustment mechanism may used implemented to adjust the difference in the optical path lengths of the first and second beams to produce a variable DGD. When the depolarization of light is desired, the difference in the optical path lengths of the first and second beams is set to be greater than the coherence length of the input optical beam.

International Classification:

A61F 7/00

US Classification:

607114

Abstract:

Systems and methods are disclosed for regulating body temperature. The system includes a housing that comprises compartments for a phase change material and a heat transfer material. The compartments are configured to transfer heat from the heat transfer material to the phase change material. A temperature sensor is used to determine when the phase change material has reached a pre-determined temperature. When the pre-determined temperature is reached, a release mechanism or lever is coupled to the temperature sensor to separate the phase change material compartment from the heat transfer material compartment or to remove the heat transfer material away from the phase change material compartment. The heated phase change material compartment can be used to regulate body temperature.
