20080306370 | Method of examining dynamic cardiac electromagnetic activity and detection of cardiac functions using results thereof - A method of examining cardiac electromagnetic activity over a heart for diagnosing the cardiac functions of the heart is disclosed. The method may include constructing a phase diagram of electromagnetic signals over a heart by collecting sets of time-dependent magnetic signals, determining the zeroth and the first derivations of each set of the magnetic signals at a given time, and categorizing the zeroth and the first derivations of the magnetic signals in either of the four phases: (+, +), (−, −), (+, −), (−, +). The method may also include monitoring a wave propagation of the magnetic signals. | 12-11-2008 |
20090030301 | Method of examining dynamic cardiac electromagnetic activity and detection of cardiac functions using results thereof - A method of examining cardiac electromagnetic activity over a heart for diagnosing the cardiac functions of the heart is disclosed. The method includes collecting a plurality of sets of spatially distributed, time-varying magnetic field signals of the heart of a subject, wherein the magnetic field signals exhibit features of at least a wave, identifying a time corresponding to a local maximum intensity of the magnetic field signals of the wave at each measurement position and plotting a temporal evolution of the local maximum intensity of the magnetic field signals during a time interval of the wave. | 01-29-2009 |
20090042198 | METHOD FOR MEASURING CONCENTRATION OF NUCLEIC ACIDS - A method for measuring a concentration of nucleic acids is described. The method includes providing bioprobe molecules that include single-stranded nucleic acids, wherein the bioprobe molecules are conjugated with magnetic beads in a solution. A sample of single-stranded target nucleic acids is added to solution, where the single-stranded target nucleic acids hybridize with the single-stranded nucleic acids of the bioprobe molecules. A reduction of the ac (alternating current) magnetic susceptibility of the solution prior and after the addition of the sample to the solution is determined. | 02-12-2009 |
20090325317 | METHOD AND SYSTEM FOR SUPPRESSING BINDINGS ON MAGNETIC PARTICLES - A method for suppressing non-specific bindings between molecules includes providing magnetic particles dispersed in a liquid, wherein each of the magnetic particles has a magnetization. The magnetic particles are coated with coating molecules. Binding molecules mixed of first-type binding molecules and second-type binding molecules are applied to the liquid, wherein the coating molecules are specifically binding with the first-type binding molecules and non-specifically binding with the second-type binding molecules. An alternating current (ac) magnetic field is applied at an axis with a frequency level, wherein the frequency level causes suppression of the second-type binding molecules in binding with the coating molecules. | 12-31-2009 |
