| 20090001049 | METHODS OF ETCHING ARTICLES VIA MICROCONTACT PRINTING - Improved methods of forming a patterned self-assembled monolayer on a surface and derivative articles are provided. According to one method, an elastomeric stamp is deformed during and/or prior to using the stamp to print a self-assembled molecular monolayer on a surface. According to another method, during monolayer printing the surface is contacted with a liquid that is immiscible with the molecular monolayer-forming species to effect controlled reactive spreading of the monolayer on the surface. Methods of printing self-assembled molecular monolayers on nonplanar surfaces and derivative articles are provided, as are methods of etching surfaces patterned with self-assembled monolayers, including methods of etching silicon. Optical elements including flexible diffraction gratings, mirrors, and lenses are provided, as are methods for forming optical devices and other articles using lithographic molding. A method for controlling the shape of a liquid on the surface of an article is provided, involving applying the liquid to a self-assembled monolayer on the surface, and controlling the electrical potential of the surface. | 01-01-2009 |
| 20090050790 | MULTI-ELEMENT OPTICAL DETECTORS WITH SUB-WAVELENGTH GAPS - A multi-element optical detector includes a plurality of optical detector elements capable of producing an output signal having information about the state of an incident electromagnetic radiation as a function of time. An active region includes a photosensitive region of one of the optical detector elements separated in part or in whole from the photosensitive region of at least one other optical detector element by a distance less than the wavelength of the electromagnetic radiation that the optical detector elements are being used to detect. | 02-26-2009 |
| 20090092803 | SELF-ASSEMBLY TECHNIQUE APPLICABLE TO LARGE AREAS AND NANOFABRICATION - The present invention provides articles and methods for affecting the self-assembly of materials. In some cases, the invention provides an approach for facilitating the self-assembly of various materials, including polymeric materials (e.g., block polymers), nanoparticles, other materials capable of self-assembly, and the like, over relatively large surface areas. Some embodiments of the invention provide articles (e.g., substrates) which, when contacted with a material capable of self-assembly, may produce greater control of self-assembly through the bulk of the material. | 04-09-2009 |
| 20100078854 | Nanotemplate arbitrary-imprint lithography - In a method for imprinting a layer of material, a nanotemplate is impressed into a material layer, and the nanotemplate is maintained impressed in the material layer until a geometric trench corresponding to geometry of the nanotemplate is formed in the layer, and the nanotemplate is then removed from the material layer. A nanotemplate geometric trench is repeatedly formed in the material layer by nanotemplate impressions in the layer, until a final desired imprint pattern is produced in the layer. Each nanotemplate geometric trench is characterized by an extent that is a fraction of an extent of the final desired imprint pattern. The material layer is maintained in a condition for accepting nanotemplate impressions continuously throughout the nanotemplate impression repetition. | 04-01-2010 |

| 20090229815 | Apparatus and Method for Extracting Petroleum from Underground Sites Using Reformed Gases - Methods and apparatus for removing oil or natural gas from the ground. In one example, the method may include reforming a fuel source by reaction with water to generate driver gas, and injecting the driver gas into the oil well. The reforming operation may include causing the combustion of a combustible material with ambient oxygen for the release of energy; and heating a reforming reaction fuel and water sources, with the energy released from the combustion of the combustible material, to a temperature above that required for the reforming reaction wherein the fuel and water sources are reformed into driver gas. In one example, the amount of the combustible material combusted is sufficient to result in the release of enough energy to heat an amount of the reforming reaction fuel and water sources to the temperature above that required for the reforming reaction to proceed. The driver gas may be used to help extract oil from the ground and especially oil from depleted oil wells. It may also be used to drive natural gas trapped underground or in coal beds to the surface. | 09-17-2009 |

| 20110304497 | Athletic Performance Monitoring Systems and Methods in a Team Sports Environment - Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal. | 12-15-2011 |
