Abstract: A single-dose oral hygiene unit of a toothpaste composition is blended together using a method of manufacturing disclosed herein. The oral hygiene units define an outer surface that is easily manipulated with a user's fingers. The ingredients are first blended together to create a final, blended toothpaste composition. A predetermined weight of blended toothpaste composition is extruded via nozzles into a plurality of cavities defined in a mold tray. The mold tray containing blended toothpaste composition is refrigerated for a predetermined time at a predetermined temperature until the blended toothpaste composition solidifies and the single-dose oral hygiene units are formed. The units may undergo a coating process whereby the outer surface of each unit is coated with an ingredient that prevents one or more units from sticking to one another or the container in which the units are placed and dispensed from.

Abstract: A method of detecting defects using eddy currents is disclosed. The method comprises: exciting eddy currents in a test material using an eddy current probe driven by a drive signal; detecting induced eddy currents in the test material; converting the detected signal into integer values using an analog to digital converter; and adding or subtracting the generated integer values to or from each of two accumulators, or taking no action, so that one accumulator produces a value proportional to one component of the detected signal and the other produces a value proportional to another component of the detected signal and using these values to detect the presence of a defect.
