| 20120118045 | INTEGRATED OPTOELECTROCHEMICAL SENSOR FOR NITROGEN OXIDES IN GASEOUS SAMPLES - A gas-phase detection system based on detecting optochemical and optoelectrochemical signals. The sensing platform is particularly powerful for detection of nitrogen oxides at low ppbV concentrations. The optochemical analysis is based on the color development due to a chemical reaction taking place in an optimized material. The electrochemical analysis can be based on the doping level or redox potential changes of an electrochemical sensor; and optoelectrochemical detection can be based on a combination of the electrochemical and optoelectrochemical methodologies. Each independent signal can be simultaneously detected, increasing the reliability of detection. | 05-17-2012 |
| 20120009491 | METAL-AIR ROOM-TEMPERATURE IONIC LIQUID ELECTROCHEMICAL CELL WITH LIQUID FUEL - Provided in one embodiment is an electrochemical cell for generating power, and more particularly to a metal-air electrochemical cell using a low temperature ionic liquid and a liquid metal fuel. | 01-12-2012 |
| 20110281184 | METAL-AIR CELL WITH PERFORMANCE ENHANCING ADDITIVE - Systems and methods drawn to an electrochemical cell comprising a low temperature ionic liquid comprising positive ions and negative ions and a performance enhancing additive added to the low temperature ionic liquid. The additive dissolves in the ionic liquid to form cations, which are coordinated with one or more negative ions forming ion complexes. The electrochemical cell also includes an air electrode configured to absorb and reduce oxygen. The ion complexes improve oxygen reduction thermodynamics and/or kinetics relative to the ionic liquid without the additive. | 11-17-2011 |
| 20110120868 | Nanopore and Carbon Nanotube Based DNA Sequencer and a Serial Recognition Sequencer - The present invention is directed to systems, devices and methods for identifying biopolymers, such as strands of DNA, as they pass through a constriction such as a carbon nanotube nanopore. More particularly, the invention is directed to such systems, devices and methods in which a newly translocated portion of the biopolymer forms a temporary electrical circuit between the nanotube nanopore and a second electrode, which may also be a nanotube. Further, the invention is directed to such systems, devices and methods in which the constriction is provided with a functionalized unit which, together with a newly translocated portion of the biopolymer, forms a temporary electrical circuit that can be used to characterize that portion of the biopolymer. | 05-26-2011 |
| 20110038497 | Microphone Devices and Methods for Tuning Microphone Devices - The present invention relates generally to microphone devices useful, for example, in hearing aid devices. The present invention relates more particularly to tunable microphone devices, and methods used to tune them. One aspect of the present invention is a microphone device that includes at least one microphone element. Each microphone element comprises a diaphragm suspended by a substrate; a solid electrolyte disposed on the diaphragm; an anode electrically coupled to the solid electrolyte; and a cathode electrically coupled to the solid electrolyte. The solid electrolyte is disposed between the anode and the cathode, such that ions flowing from the anode to the cathode travel through the solid electrolyte and electrons can flow in the opposite direction. | 02-17-2011 |
| 20100286747 | METHODS FOR APPLYING BRAIN SYNCHRONIZATION TO EPILEPSY AND OTHER DYNAMICAL DISORDERS - For analyzing a multi-component system, a method acquires a plurality of signals, each having a different spatial location of the multi-component system, and generates dynamic profiles for each of the plurality of signals. Each of the plurality of dynamic profiles reflects dynamic characteristics of the corresponding signal in accordance with each one of a plurality of dynamic measures. The method selects pairs of dynamic profiles from the acquired dynamic profiles based on a predetermined level of synchronization and generates a statistical measure for each of the selected plurality of pairs of dynamic profiles. The method characterizes state dynamics of the multi-component system as a function of at least one of the generated statistical measures, and generates a signal indicative of the characterized state dynamics of the multi-component system. The method enables seizure detection, seizure prediction, seizure focus localization, differential diagnosis of epilepsy and evaluation of seizure intervention strategies | 11-11-2010 |
| 20100248977 | Immobilizing an Entity in a Desired Orientation on a Support Material - The present invention relates to the identification and selection of attachment molecules that attach/immobilize an entity having a detectable activity or property on a support in an orientation that provides a detectable activity or property, and to surfaces made of the attachment molecules. | 09-30-2010 |
| 20090175949 | MICROPARTICLES FOR DELIVERY TO CELLS AND/OR TISSUES - Delivery of bioactive molecules (BAMs) to organelles, cells, tissues, or animals with high efficiency is desirable. Novel compositions for highly efficient delivery of bioactive molecules by biolistic methods are described. The novel compositions include novel microparticle cores, microparticle core/BAM complexes, microparticle core/nanoparticle complexes and multilayer-microparticle core/BAM complexes. Any one of these may be further modified to include targeting agents. | 07-09-2009 |
| 20090042741 | MICROARRAY OF THREE-DIMENSIONAL HETEROPOLYMER MICROSTRUCTURES AND METHOD THEREFOR - A microarray has a substrate and a plurality of three-dimensional microstructures formed on the substrate. Each of the three-dimensional microstructures is made with polymer material and has a plurality of reactive sites formed on its surface and interior pores. The polymer material is polymer gel or other porous polymer. The combination of three-dimensional microstructure and porous polymer material increases the surface area of the microstructure and density of the reactive sites on the surface of the microstructures. The higher density of reactive sites increases the luminescence, visibility or instrument detectability of the interaction between analytes and reactive microstructure sites on the microarray. A plurality of chemical groups are respectively attached to the reactive sites. The chemical groups each include at least one monomer. The chemical groups may have different chemical structures. A plurality of microchannels can be formed around the microstructures for isolation. | 02-12-2009 |
