Publication number: 20090088982Abstract: The invention relates to a method for co-detecting and distinguishing individual polypeptide and polynucleotide molecules in a single sample analysis. The polypeptide and polynucleotide targets which emit electromagnetic radiation are labeled with probes that emit electromagnetic radiation at the same emission wavelength, are suspended in fluid and moved through an interrogation volume allowing co-detection of low concentrations of individual molecules and discrimination based on characteristics other than emission wavelength.Type: ApplicationFiled: July 31, 2004Publication date: April 2, 2009Inventors: Noelle H. Fukushima, Robert S. Puskas

Patent number: 7512499Abstract: A system and method are disclosed for very accurately determining a value of a substrate doping density in a metal oxide semiconductor device. A plurality of values of threshold voltage of a device under test are measured using a plurality of different values of source to substrate bias voltage. Then a linear relationship is determined between the plurality of values of threshold voltage and a plurality of different values of an expression that is a function of the source to substrate bias voltage and a function of a surface potential of the device. A very accurate value of the substrate doping density is reiteratively calculated from the linear relationship without assuming that the surface potential of the device has a constant value.Type: GrantFiled: December 20, 2006Date of Patent: March 31, 2009Assignee: National Semiconductor CorporationInventors: Jiankang Bu, William S. Belcher

Patent number: 7504230Abstract: The present invention is a cell-based method of identifying a set of signal transduction proteins having an intracellular localization pattern responsive to toxic compounds. The method requires identifying and screening an initial set of signal transduction proteins against a set of toxic compounds, and determining changes in intracellular localization pattern of each of the proteins. Proteins whose changes in intracellular localization pattern are redundant are discarded from the initial set, and new proteins are added to provide a new set of proteins. I repeat the method steps with new sets of proteins until the set of proteins provides me at least 5 principal components with respect to the range of compounds marketed as small organic molecules.Type: GrantFiled: November 13, 2003Date of Patent: March 17, 2009Assignee: Trelolis Bioscience, Inc.Inventor: Lawrence M.

Patent number: 7502693Abstract: A spectroscopic identification method and system are provided that uses the primary or main spectroscopic features of a source, such as those as arising from chemical functional groups, to describe and distinguish the source. These primary spectroscopic features make up a portion (i.e., are a subset) of the entire spectroscopic data for a particular source but can nevertheless be used as the basis of separating spectra from multiple source. When analyzing spectroscopic data obtained from a sample for one or more sources, the analysis first focuses on the primary spectroscopic features for a source rather than the entire spectra for a source.Type: GrantFiled: September 27, 2007Date of Patent: March 10, 2009Assignee: ITT Manufacturing Enterprises, Inc.Inventors: Mohamed-Adel Slamani, Thomas H. Chyba, Ryan E. Da Re, James E. Pendell Jones
