20100136316 | LAMINATED COMPOSITES AND METHODS OF MAKING THE SAME - The instant disclosure relates to a laminated composite and methods of making the same. The laminated composite includes a plurality of stacked prepregs having an interface formed between each pair of adjacent prepregs. Each prepreg includes a matrix material and reinforcing fibers dispersed therein. At least one fibrous veil is laminated to at least a portion of at least one of the interfaces, the at least one fibrous veil having graphite nano-platelets attached to at least one surface thereof. | 06-03-2010 |
20110062628 | METHOD FOR MOLDING COSMETIC COMPOSITE PANELS WITH VISIBLE CARBON FIBER WEAVES - One embodiment of the invention provides a method for compression molding cosmetic panels with visible carbon fiber weaves using clear or lightly filled resins. The method uses a modified, two-step compression molding process to reflow the surface of a partially cured preform of carbon fiber weave and epoxy resin. | 03-17-2011 |
20110244744 | LAMINATED COMPOSITES AND METHODS OF MAKING THE SAME - The present disclosure relates to a fibrous veil and methods of making the same. The fibrous veil includes a base having a plurality of fibers, each of the plurality of fibers having an average diameter ranging from about 7,000 nm to about 9,000 nm. Graphite nano-platelets are attached to at least some of the plurality of fibers without a polymeric binder. | 10-06-2011 |

20090134816 | Self adjusting power supply apparatus and method - Apparatus and methods are disclosed that control power supplies to automatically provide the appropriate voltage to drive constant current devices. A lighting system according to the present invention comprises a lighting module having a constant current device that provides a constant current in response to constant current voltage. A power supply is included that generates a power supply voltage coupled to the lighting module. A feedback circuit is included from the lighting module to the power supply causing the power supply voltage to be sufficient to provide a constant current voltage at the LED module. A method according to the present invention for generating a constant current voltage to drive a constant current device, comprises providing a drive voltage to a constant current device. The current at the constant current device is sensed a first time, and the drive voltage is increased. The current to the constant current device is sensed a second time. The drive current is held at its increased level if the current did not increase from the first to the second sensing. The increasing of the drive voltage and sensing of the current is repeated of the current did increase between the first and second sensing. | 05-28-2009 |
