| 20100045194 | POWERING AND CONTROLLING LIGHT EMITTING DIODES VIA THERMALLY SEPARATED ARRAYS OF DISSIPATIVE ACTIVE ELEMENTS - A chipset for powering and controlling a plurality of light emitting diode (LED) strings. The chipset includes a controller having a pulse width modulating (PWM) functionality and a data transfer interface circuitry; and at least one dissipative active element array comprising a plurality of dissipative active elements. The dissipative active element array(s) are packaged to be thermally separate from the controller. The PWM functionality is arranged to individually pulse width modulate a current flow through each of the LED strings. Each of the plurality of dissipative active elements is associated with a particular one of the plurality of LED strings and is arranged to limit the current flow of the pulse width modulated current that flows through the particular LED string to a value, the value being responsive to a value output by the controller via the data transfer interface circuitry. | 02-25-2010 |

| 20090295408 | NANOSTRUCTURED SURFACE FOR MICROPARTICLE ANALYSIS AND MANIPULATION - The present invention provides an apparatus, comprising a first mechanical structure having a first rigid surface, an area of the first rigid surface having a nanostructured surface. The apparatus also includes a second mechanical structure having a second rigid surface and opposing the first mechanical structure. The second rigid surface is cooperable with the nanostructured surface such that a microscopic particle is locatable between the nanostructured surface and the second rigid surface. | 12-03-2009 |
| 20110086766 | Chemical and Biological Detection Arrays - Device comprising: a first substrate; a plurality of first raised elements on the first substrate, the first raised elements mutually spaced apart by first channel regions on the first substrate, each of the first raised elements having a first distal end, the first distal ends forming a first array; hydrophobic molecules on the first raised elements; and primary reactive molecules on the first raised elements for generating hydrophilic reaction products. Techniques for utilizing the device. | 04-14-2011 |

| 20110077172 | ASSEMBLY AND DEPOSITION OF MATERIALS USING A SUPERHYDROPHOBIC SURFACE STRUCTURE - Fluidics-induced localized deposition and assembly of materials using a superhydrophobic surface structure is described. A method of localized deposition of a material includes contacting a superhydrophobic substrate comprising raised surface structures with a non-wetting fluid comprising a material to be locally deposited or a precursor thereto, said surface and said fluid selected such that the fluid wets only an upper portion of the raised surface structure; and allowing the material to deposit at the tips of the surface structure. | 03-31-2011 |
