Abstract: A computer-implemented method of matching color elements for objects having different source color definitions within a print job prior to printing, includes identifying all source colors to be printed within the print job and object type associated with each instance of a source color; identifying any source colors having at least two different source color definitions; for each source color having at least two different source color definitions, selecting one of the source color definitions in accordance with a predetermined criterion; and assigning the selected source color definition to at least one other instance of the source color for that object type. The predetermined criterion may include for each source color having at least two different source color definitions for the same object type, assigning the selected source color definition to all other instances of the source color for that object type.

Abstract: The present invention provides modified cyclic nucleotide gated (CNG) channels. In particularly preferred embodiments, the modified CNG channels exhibit increased sensitivity and specificity for cAMP, as compared to wild-type CNG channels. In additional embodiments, regulation by Ca2+-calmodulin has been removed in the modified CNG channels. Convenient optical methods for detecting changes in cAMP, taking advantage of the Ca2+ permeability of the channel are also provided by the present invention. In addition, electrophysiological methods are further provided.

Abstract: To limit the accumulation of recursive computation errors while recursively calculating the discrete Fourier transform of an input signal in response to moving window sample sets of that signal, the dependent variables for the recursive calculations are periodically refreshed. One embodiment generates an error limited continuous discrete Fourier transform of the input signal through the use of duplicate channels which are periodically reinitialized in time staggered relationship and alternately switched on-line and off-line in time synchronism with the reinitialization process. Each of the channels of that embodiment is equipped to recursively calculate the discrete Fourier transform of the input signal so that while one channel is on line feeding recursively calculated transform coefficients to the outputs, the other channel or channels are off-line being reinitialized and then computing fresh sets of transform coefficients for subsequent on-line recursive calculations.
