20090047558 | MICRO-MACHINED FUEL CELLS - An improved fuel cell is described. The invention addresses the problem of mechanical failure in thin electrolytes. One embodiment varies the thickness of the electrolyte and positions at least either the anode or cathode in the recessed region to provide a short travel distance for ions traveling from the anode to the cathode or from the cathode to the anode. A second embodiment uses a uniquely shaped manifold cover to allow close positioning of the anode to the cathode. Using the described structures results in a substantial improvement in fuel cell reliability and performance. | 02-19-2009 |

20100151602 | LASER ROUGHENING TO IMPROVE LED EMISSIONS - An improved method of forming a LED with a roughened surface is described. Traditional methods of roughening a LED surface utilizes strong etchants that require sealing or protecting exposed areas of the LED. The described method uses a focused laser to separate the LED from the substrate, and a second laser to roughen the LED surface thereby avoiding the use of strong etchants. A mild etchant may be used on the laser roughened LED surface to remove unwanted metals. | 06-17-2010 |

20110185925 | Digital Gravure Printing with a Pixilated Photoconductor - A printing sub-system including same including a pixilated photoconductive member (such as a photobelt) is disclosed. Electrically isolated cells hold surface application material above the photoconductor. The surface application material is first charged. Charge on the surface application material in an individual cell may then be discharged by exposure of a region of the photoconductor proximate that cell to light from an optical addressing system. The surface application material is brought into proximity of an image receiving member such as paper, which is either charged or proximate a charge source. Charged surface application material in a cell may then be electrostatically transferred from the cell onto the image receiving member, while discharged surface application material remains in the cell. The subsystem may form a part of a complete printing system using many existing components. Among other advantages, viscous liquid surface application material may thereby be printed. | 08-04-2011 |

The received signal is a superposition of the transmit signal and the reflected signal as result of interference. The received signal is representative of differences in acoustic impedances across the surface. | 06-14-2012 |
