| 20080231669 | AERODYNAMIC ERROR REDUCTION FOR LIQUID DROP EMITTERS - A method is disclosed for forming a liquid pattern of print drops impinging a receiving medium according to liquid pattern data using a liquid drop emitter that emits a plurality of continuous streams of liquid at a stream velocity, v | 09-25-2008 |
| 20080278548 | PRINTER HAVING IMPROVED GAS FLOW DROP DEFLECTION - A drop generator operable to selectively form a drop having a first size and a drop having a second size from liquid emitted through a nozzle associated with the drop generator. The drop having the first size and the drop having the second size travel along a drop trajectory with the first size being larger than the second size when compared to each other. Each of the drops has a drop velocity. A gas flow deflection system includes a gas flow that is directed at a deflection zone that comprises at least a portion of the drop trajectory. The gas flow in the deflection zone includes a velocity vector having a parallel velocity component and a perpendicular velocity component with the parallel velocity component and the perpendicular velocity component being defined relative to the drop trajectory. | 11-13-2008 |
| 20090244180 | FLUID FLOW IN MICROFLUIDIC DEVICES - A microfluidic device comprising a monolithic superstructure, wherein the superstructure contains fluid channels, and in at least one of the fluid channels, in an area where the channel changes direction or intersects another channel, the channel is greater in cross-section than in other areas of said channel. | 10-01-2009 |
| 20100043659 | METHOD FOR REGISTERING PATTERNS ON A WEB - A method for registering patterns on a web to provide independent scale control in both the lateral and longitudinal directions is provided. The method includes routing the web over a first roller; routing the web over a second roller and stabilizing the web; applying a pattern to the web using process hardware; measuring registration of the pattern and providing an error signal; controlling lateral position error using the error signal; controlling longitudinal position error using the error signal; controlling lateral scale error using the error signal; and controlling longitudinal scale error using the error signal. The method provides independent scale control in both the lateral and longitudinal directions. Independent scale control avoids non-linear distortions otherwise imposed by attempting to accomplish both corrections by stretching the web in both directions. | 02-25-2010 |
| 20100199972 | Apparatus and Method for Building Linear Solar Collectors Directly from Rolls of Reflective Laminate Material - Provided herein are linear solar reflectors and collectors, and methods of efficiently constructing such reflectors and collectors. The reflectors are made using reflective laminate sheets, which can be reinforced by tension-bearing strips. Methods and apparatuses for installing the sheets from a roll dispensing the sheets carried on a deployment vehicle are disclosed, as well as methods and apparatuses for assembling and constructing various collector components, methods and apparatuses for tensioning the reflective laminate sheets, methods and apparatus for passively changing the focal length of the reflectors while controlling their movement to track the sun, and methods and apparatuses for compensating for temperature changes in system components for moving the collectors, are provided. | 08-12-2010 |
| 20100206233 | Device and Method for Vaporizing Temperature Sensitive Materials - A device vaporizes organic materials onto a substrate surface to form a film. The device includes a vaporization apparatus to receive a quantity of organic material that can have one or more components each having a different vaporization temperature, the vaporization apparatus having a first region and a second region spaced from the first region; a cooling unit to actively cool the organic material in the first region so that each of the one or more organic components is maintained well below its vaporization temperature to reduce degradation of the organic material; heating unit to heat the second region of the vaporization apparatus above the vaporization temperature of each of the one or more organic components; and a metering unit having a permeable member to meter organic material at a controlled rate from the first region into the second region so that a thin cross section of the organic material is heated at a desired rate-dependent vaporization temperature, whereby organic material vaporizes and forms a film on the substrate surface. | 08-19-2010 |

| 20110143227 | Metal Oxygen Battery Containing Oxygen Storage Materials - A battery system includes a metal oxygen battery. The metal oxygen battery includes a first electrode and a second electrode. The second electrode includes a metal material (M). The metal oxygen battery is in communication with an oxygen storage material. In certain instances, the oxygen storage material is contained within an oxygen containment unit. The metal oxygen battery and the oxygen containment unit may be in a closed-loop with respect to each other. The battery system further includes a conduit for providing fluid communication from one of the metal oxygen battery and the oxygen containment unit to the other of the metal oxygen battery and the oxygen containment unit. | 06-16-2011 |
| 20110165492 | FUEL CELL HEADER WEDGE - A fuel cell system may include a fuel cell stack having a header and active area in fluid communication with the header. The fuel cell system may also include a wedge disposed within the header and configured to alter the cross-sectional area of the header along the length of the stack such that, during operation of the stack, a flow velocity of gas through the active area is generally constant. | 07-07-2011 |
| 20110165500 | FUEL CELL STACK THAT PROMOTES GENERALLY UNIFORM FLOW THEREIN - A power generating system may include a plurality of bipolar plates stacked to form a fuel cell assembly having an inlet side, a non-inlet side, an inlet header extending from the inlet side to the non-inlet side, an active area, and an inlet transition area. The inlet transition area may be in fluid communication with (i) the inlet header via feed passageways formed in each of the plates and (ii) the active area. The feed passageways of the plates located proximate to the inlet side may be generally smaller and/or fewer in number than the feed passageways of the plates located proximate to the non-inlet side such that, during operation of the fuel cell assembly, a flow velocity of gas through the active area is generally constant. | 07-07-2011 |
