Abstract: One embodiment of the current invention seeks to increase heat dissipation in solid state lights used in track lighting systems, by utilizing a track with a fluid channel. Convective heat transfer within this fluid channel acts to dissipate more heat than can be typically dissipated by conventional solid state lights themselves, thus allowing for brighter, higher-powered lights. The track and fluid channel can take on various forms.

Abstract: An oil, gas or water borehole drill bit protector apparatus (10, 100, 200, 300, 400) comprises one or more protector portions (10A, 10B; 100A, 100B) adapted to be placed around and/or adapted to envelope at least a drilling portion of the drill bit; and the one or more protector portions comprising an aperture (16) through which a connection portion of the drill bit projects in use. The one or more protector portions are placed around and/or enveloping the drilling portion of the drill bit; and closed around the drilling portion of the drill bit such that the connection portion of the drill bit projects through the aperture of the one or more protector portions.

Abstract: Photonic signals are tagged with a pre-selected modification, such as a polarization signature to carry data across an obstructed path between sender and receiver. Communication authentication through polarization variation allows for Yuen-Kumar or entangled photon quantum communication protocols to propagate through environmental scattering media such as air, smoke, fog, rain, and water. While ultraviolet light photons are well suited as a carrier for quantum communication signals scattered in air, it is appreciated that visible wavelengths have longer propagation paths in water to convey non-line-of-sight data. A secure signal is scattered by the media and simultaneously communicated to a single recipient or multiple recipients exposed to scattered signal portions. A process of solving the scattering processes through a random scattering media is provided to reconstruct a quantum keyed message at a receiver.

Abstract: Embodiments of the current invention seek to increase heat dissipation by affixing a separate or integrated heat sink to the solid state light, thus accomplishing increased heat dissipation via another device, instead of altering the solid state light itself. In this manner, embodiments of the invention increase the amount of heat dissipated from solid state lights without requiring any redesign of the solid state lights themselves.
