Abstract: A mixed-size copy printer system and method may include a scanner for collecting raw image data from and detecting a length of an original page from among a plurality of original pages of different lengths, a printer for printing an image scanned from an original page on a copy page, a controller including a plurality of stored print instructions and a RAM buffer, and an image processing unit, whereby the image processing unit may be configured to receive from the scanner the raw image data from the data indicative of a length of an original page scanned by the scanner, store the image data in the RAM buffer while the controller selects a print instruction from among the stored print instructions in response to the data indicative of the length of the original page scanned by the scanner, and the image processing unit sends the image data and the controller sends selected print instruction to the printer.

Abstract: An accurate, relatively low cost and reliable apparatus and method for measuring the magnitude or degree of polarization of light, particularly adaptable to the measurement of fluorescence polarization. An electric field in sequentially applied to a field-effect liquid crystal to sequentially apply respective perpendicular polarization components from a light source to a fixed polarizer having a fixed plane of polarization. The respective polarization components are sequentially applied to detector and measuring apparatus for determining the magnitude of polarization. Memory means are included for storing a correction factor to compensate for polarization rotation errors due to the liquid crystal. Stored in the memory means is a correction factor for a range of measured values, the correction factor being obtained by direct comparisons with expected values for known polarizations.
