Abstract: Currency processing systems, coin processing machines, coin imaging sensor assemblies and methods of making and methods of using the same are presented herein. A currency processing system is disclosed which includes a housing with a coin input area for receiving coins and coin receptacles for stowing processed coins. A disk-type coin processing unit, which is coupled to the coin input area and coin receptacles, includes a rotatable disk for imparting motion to coins, and a sorting head for separating and discharging coins to the coin receptacles. A sensor assembly is mounted to, adjacent or within the sorting head adjacent the rotatable disk. The sensor assembly includes a linear array of sensors, wherein the linear array of sensors is configured to sense coins processed by the coin processing unit, and to output a signal indicative of coin image information for processing the coins.

Abstract: A system and method for a pulsed light source used in detecting fluorescence from a plurality of samples of biological material discretely, continuously or intermittently during thermal cycling of DNA to accomplish a polymerase chain reaction (PCR). An apparatus for sampling at least one sample of a biological material comprises a light source that emits a pulsed excitation light that interacts with the sample and a detector sensitive to fluorescence emitted from the sample. A method of sampling at least one sample to detect fluorescence comprises generating a pulsed excitation light with a pulsed light source; directing the pulsed excitation light into the sample; illuminating a sample with the pulsed excitation light to generate an emission light; and detecting the optical characteristics of the emission light.
