Abstract: The present invention relates to a method for preparing an enantiomerically enriched form of 3-(2-chlorothiazol-5-yl)-8-methyl-7-oxo-6-phenyl-2,3-dihydrothiazolo[3,2-a]pyrimidin-4-ium-5-olate.

Abstract: Media thickness and double sheet detection system includes a CPU for managing input and outputs to/from each operational module, media input handling and storage hardware, a pickup controller manages the input of media from the media input handling and storage hardware into the system, a speed sensor, detecting the speed of the media moving through the system, a thickness sensor detecting the thickness of the media moving through the system, a direction sensor detecting the movement direction of the media through the system, a friction sensor detecting tension of the media when movement of at least one roller that makes up a pair of complimentary pinch rollers is reversed while the other roller is held in a brake position, and a reverse roller and brake roller control module managing the reversal of the least one pinch roller and braking of the complimentary roller.

Abstract: A device and method for validating a document having magnetic ink thereon after determining the existence of a document having magnetic ink thereon. The ink is magnetized and thereafter to a media reader sensor spaced from the document by a predetermined gap to verify the existence of a magnetic signal and rejecting documents without a magnetic signal. The magnetic signal is compared to a set of preexisting data to determine the existing of a signal to data match and validate only documents that have a match between the magnetic signal and pre-existing data. A set/reset sensor is preferably used to apply a signal to the magnetic ink on the document. A preferred predetermined gap is from about 0.25 mm to about 1.5 mm, and most preferred from about 0.5 mm to about 1.0 mm. Preferred comparators are microprocessors and preferred media reader sensors are anisotropic magnetoresistive sensors.

Abstract: A device and method for validating a ticket having magnetic ink printed on at least one side of a ticket. The ink is magnetized to create a magnetic signal in the magnetic ink and thereafter a media reader sensor spaced from the ticket is used to verify the existence of a magnetic signal. The magnetic signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. An optical reader can be used to obtain additional data stored in the form of bar codes or patterns on the printed magnetric ink. The optical signal is comparable to pre-existing data to determine a match and/or validate tickets having a match. Preferred comparators for magnetic and optical matching are microprocessors and preferred media reader sensors for magnetic readers are anisotropic magnetoresistive sensors.
