| 20110070574 | METHOD FOR VIRUS DETECTION - A method of determining the concentration of a virus or antigen thereof in a sample comprises the steps of: providing a sensor surface having immobilized thereto a virus antigen or a virus antigen analogue, mixing the sample with a known amount of antibody to the virus antigen to obtain a predetermined concentration of antibody to the antigen in the sample mixture, contacting the sample mixture with the sensor surface to bind free antibody in the mixture to the sensor surface, measuring the response of the sensor surface to the binding of free antibody, and determining the concentration of the virus or antigen in the sample from a calibration curve prepared by measuring the responses obtained for mixtures containing the predetermined concentration of antibody and different concentrations of virus. | 03-24-2011 |
| 20110076703 | CONCENTRATION ASSAY - A method of determining the concentration of at least one analyte in a plurality of samples by sequentially subjecting each sample to an analysis cycle comprises contacting the sample or a sample-derived solution with a sensor surface supporting a species capable of specifically binding the analyte or an analyte-binding species, detecting the amount of binding to the sensor surface, and regenerating the sensor surface to prepare it for the next analytical cycle, and based on the detected binding to the sensor surface determining the concentration of analyte in each sample using virtual calibration data calculated for each analysis cycle from real calibration data obtained by contacting the solid phase with samples containing known concentrations of analyte. | 03-31-2011 |

| 20100026780 | Electronic device directional audio capture - Disclosed herein is an apparatus. The apparatus includes a housing, electronic circuitry, and an audio-visual source tracking system. The electronic circuitry is in the housing. The audio-visual source tracking system includes a first video camera and an array of microphones. The first video camera and the array of microphones are attached to the housing. The audio-visual source tracking system is configured to receive video information from the first video camera. The audio-visual source tracking system is configured to capture audio information from the array of microphones at least partially in response to the video information. The audio-visual source tracking system might include a second video camera that is attached to the housing, wherein the first and second video cameras together estimate the beam orientation of the array of microphones. | 02-04-2010 |

| 20090254146 | DEEP BRAIN STIMULATION IMPLANT WITH MICROCOIL ARRAY - An implant for deep brain stimulation (DBS) has an array of electromagnetic microcoils dispersed over the length of the implant. The microcoils produce magnetic fields that are directed into, and induce current in, the adjacent brain tissue. The microcoils may be selectively operated to direct and focus electrical stimulation to targeted areas of the brain. The implant is useful in studying or treating neurophysiological conditions associated with the deep regions of the brain such as Parkinson's disease, drug addiction, and depression. | 10-08-2009 |
