20100002452	Luminaire housing with separated lamp and ballast compartments - A luminaire housing with a lamp compartment and ballast compartment that are isolated from each other is provided. The housing includes a lamp compartment, a ballast compartment, and an air gap chamber separating the two compartments from each other. The air gap chamber provides a degree of thermal isolation that reduces the amount of heat generated by the lamps that is transferred from the lamp compartment to the ballast compartment. The luminaire can also include a ventilated top cover and a bottom door configured to attach to the lamp compartment while leaving an air gap therebetween. These and other optional features improve the air circulation within the lamp compartment and allow heat generated by the lamps to exit the luminaire housing, further reducing the heat transferred to the ballast compartment, thereby improving the lifespan and performance of the ballasts.	01-07-2010

20090303570	Tunable cavity resonator and method for fabricating same - An example tunable cavity resonator for filtering radiation in the optical and IR wavelengths and an example method for fabricating same. The example resonator includes a pair of reflectors, one in fixed relationship to a substrate and the other formed upon a suspended moveable membrane disposed a cavity length from the one reflector. The resonator also includes a pair of spaced apart electrodes either constituted by the reflectors or juxtaposed therewith, which are electrostatically operable to move the membrane and other reflector relative to the one reflector.	12-10-2009

20100283885	METHOD FOR ALIGNING PIXILATED MICRO-GRID POLARIZER TO AN IMAGE SENSOR - Aligning a cut-to-size (off-wafer) pixilated micro-grid polarizer to a ready packaged imaging sensor having multiple pixels involves minimizing a separation distance between the two units and then aligning respective corresponding pixels of the pixilated micro-grid polarizer with the pixels of the imaging sensor using optical signals as position feedback during the alignment process. Once the alignment has been achieved, the micro-grid polarizer may be affixed to the imaging sensor, for example using optical epoxy glue.	11-11-2010
