A method and apparatus for identifying an article and detecting its unauthorized movement comprises disposing a predetermined amount of radioactive isotopes on or within the article. The plurality of radioactive isotopes has a characteristic gamma spectrum unique to that plurality. Continuous monitoring is used to obtain a signal to detect unauthorized movement of the article. For identification purposes, means is provided for resolving the unique gamma spectrum into isotopic abundances. The plu...

Heart tissue near the surface of the heart is characterized to identify a potential site to ablate to treat reentrant ventricular tachycardia. Signals from the surface of the heart are recorded during an episode of ventricular tachycardia to determine whether a reentrant pathway lies near the surface of the heart. Entrainment pacing is employed to identify a potential ablation site near the slow conduction zone of the reentrant pathway. Heart tissue is ablated by creating a lesion with a large s...

The invention relates to a method and an apparatus for applying flat punched elements in the desired position to the surface of a carrier material, the elements being present in multiple copies on a sheet. The multiple copies are fed to an applying device and positioned therein. At the same time as individual elements are separated out or punched, these elements are fixed in position with respect to the carrier material.

The present invention relates to methods for identifying a compound capable of modulating mitochondrial function, comprising contacting a eukaryotic cell with one or more candidate compounds, and detecting a change in the mitochondrial redox state of the cell. The methods further relates to such methods wherein endogenous fluorescence of the cell mitochondria is indicative of a change of redox state.

Methods to identify and characterize a candidate drug by detecting and recording its reactivity with each member of an antibody panel are described. A characteristic profile thus obtained can be compared with the profile obtained in an analogous manner for a ligand known to bind a target so as to identify compounds which also bind the target. A similarity in the analogously obtained characteristic profile of the candidate compound and the known ligand indicated that the candidate will bind a tar...

The invention provides methods to obtain panels of low molecular weight polymers resulting from varying constituent monomers, which panels are systematically diverse with respect to two or more variables. The panels can be screened for members (paralogs) which are capable of specifically binding a target moiety. Such paralogs are useful for chromatographic separations and purifications of desired analytes and in binding assays, such as immunoassays, involving said analytes, as well as for any pu...

An improved method for pick and place equipment operation is provided by an improved method for identifying the reference die on a wafer. A recording of good die, partial die, mirror die, and partial mirror die information about the neighboring dies about the reference die is formed by recording step is performed by starting at the reference die and moving clockwise about the reference die one die at a time to form a stored neighborhood matrix. Searching and identifying the reference die on a wa...

In a method of identifying or comparing compositions of material, the reflectivity of a material to be identified or compared is measured at index points distributed through the near infrared spectrum. A similar measurement is made for at least one standard or known material. From the reflectivity measurements, sets of values representing the first or higher order derivative curves are determined. These values mathematically define vectors by representing the coordinates of the end points of the...

A process and a device for detection of differences in yarn tension in a sheet of parallel yarn ends wherein the individual ends of the yarn sheet are deflected from a defined measuring plane, the extent of the deflection being measured.

A method and apparatus to identity SPAM emails is disclosed. The method sets a misspelling rejection ratio. Upon receipt of an email comprising (X) words, the method determines the number (Y) of misspelled words comprising that email. The method then calculates a misspelling ratio by dividing (Y) by (X), and then determines if the misspelling ratio is greater than or equal to the misspelling rejection ratio. If the method determines that the misspelling ratio is greater than or equal to the miss...
