20140327030 | CONTROLLED LED LIGHT OUTPUT BY SELECTIVE AREA ROUGHENING - The surface of a light emitting device is roughened to enhance the light extraction efficiency of the surface, but the amount of roughened area is selected to achieve a desired level of light extraction efficiency. Photo-lithographic techniques may be used to create a mask that limits the roughening to select areas of the light emitting surface. Because the amount of roughened area can be precisely controlled, the light extraction efficiency can be precisely controlled, substantially independent of the particular process used to roughen the surface. Additionally, the selective roughening of the surface may be used to achieve a desired light emission output pattern. | 11-06-2014 |

20150060888 | METHOD AND APPARATUS FOR CREATING A W-MESA STREET - A method for fabricating an epitaxial structure includes providing a wafer comprising one or more epitaxial layers. The wafer is divided into dice where the area between the dice are called streets. Each street has a slot formed on either side of the street. The slots penetrate through the epitaxial layer but not the substrate leaving a portion of the epitaxial layer intact between the slots creating a “W” shaped cross section. A protective layer is then formed on the wafer. A laser may be used to singulate the wafer in to individual dice. The laser divides each street between the slots. The barrier walls of the epitaxial layers protect the individual dice from debris created by laser separation. | 03-05-2015 |

20120292345 | Credit Card Sized Liquid Container and Dispenser - A compact liquid container/dispenser shaped and sized with the approximate dimensions of a standard sized credit card. The device includes a flat, generally square container portion capable of holding a small amount of a liquid, such as perfume or cologne. A smaller, flat, generally rectangular, lid portion is attached to the container portion along one edge with flexible hinges. A flat, pump spray dispensing component is fixed on the container portion and extends a suction tube into the liquid contained within the container portion. The lid portion may be closed over the dispensing component so as to cover the mechanism and prevent its inadvertent activation. An alternate embodiment includes a flat, generally square, removable container capsule that may be removed from and replace within the container portion of the device. | 11-22-2012 |

20130102813 | METHODS AND APPARATUS FOR SYNTHESIS OF ALCOHOLS FROM SYNGAS - This invention provides a method for producing ethanol and 2-propanol from syngas, the method comprising: (a) converting syngas into methanol using a methanol-synthesis catalyst; (b) converting methanol into ethylene and propylene using a methanol-to-olefins catalyst; and (c) hydrating ethylene into ethanol and propylene into 2-propanol. As taught herein, the combined yield of the ethanol and the 2-propanol from biomass can be at least 100 gallons per dry ton biomass. In certain embodiments, the yield of ethanol is at least 100 gallons per dry ton biomass. In some embodiments, the yield of 2-propanol is at least 50 gallons per dry ton biomass. | 04-25-2013 |
