Title: Circuit and method for controlling chrome transients
Inventor: RZESZEWSKI THEODORE S
IPC: H04N9/68
Filed: 1994-10-14
Granted: 2002-03-19
Abstract: A circuit and method for shortening the tran-sition time of sharp color transitions in color television signals.   The invention includes a pattern recognition circuit  and  method  which  directly  and  efficiently recognizes color transitions within a predetermined range. The disclosed embodiment of the invention utilizes a filter to output its step response to the pattern recognition circuit which outputs a control signal whenever the color signal rise or fall time does not fit a predetermined pattern.  When the pattern recognition circuit recognizes the step response, it directs a hold circuit to output a previous  color  signal  for a predetermined time period before allowing the transition to proceed, thus shortening the transition time.

Title: Adaptive cleaner blade lubrication
Inventor: POZNIAKAS ROBERT S
IPC: G03G21/00
Filed: 1994-10-25
Granted: 1998-08-04
Abstract: An adaptive cleaner blade lubricating system for electrophotographic printing machines. In an electrophotographic printing machine, the amount of residual toner available to lubricate a cleaner blade is calculated based on the density of the transferred image. A band of toner is deposited in an inner document gap in selective widths so as to provide an adequate amount of toner to lubricate the cleaner blade across the full width of the photoreceptor. The lubricating band may be variable or may be a constant width with the frequency of placement of the band determined based on average image density for a group of documents. In the preferred embodiment, the width of the toner band is varied as a function of the overall residual toner in each pixel location across the width of the photoreceptor based on the density of the images transferred. As a result of the varying lubrication bands, the cleaner blade is maintained so as to not tuck and cause streaking and/or damage while toner efficiency is maximized.

Abstract: A tool monitoring system monitors the condition of an electrically powered tool performing a cyclical operation. The tool monitoring system operates generally in two modes: learning mode and monitor mode. In learning mode, the tool monitoring system gathers statistical data on the power consumption of tools of the selected tool type during learning cycles. A power threshold is generated based upon the statistical data. The tool monitoring system then counts the number of crossings by each of the learning cycles of the power threshold and generates statistical data regarding the number of crossings. Preferably, the mathematical operation of wavelet packet transform is used to calculate the power threshold. Feature wavelet packets of the power consumption signal of the tool are calculated. The power consumption signal is then reconstructed from the feature wavelet packets and used to determine the power threshold. In monitor mode, the tool monitoring system counts the number of crossings of the power threshold by the power consumption signal of a tool in operation. The tool monitoring system identifies a worn tool when the number of crossings increases to a certain number relative to the crossings by the learning cycles.

Abstract: An optical power detector is provided which accurately detects the optical power of transmitted light and suffers almost no influence due to noise, and a multi-level digital transmission system which includes such an optical power detector. A beam of received light is incident into an entry end of a light fiber. A plurality of saturable absorbers are disposed in series along this light fiber, each having its own pair, differing in steps, of a first threshold value and a second threshold value which is greater than the first threshold value, and being substantially opaque to light of optical intensity below the first threshold value and substantially transparent to light of optical intensity above the second threshold value. A probe light source directs a beam of probe light to be incident upon each of the saturable absorbers in a direction crosswise to the light transmission path for the received light beam, when the received light beam is being transmitted led along the light fiber to be incident upon the saturable absorbers in order. For each of the plurality of saturable absorbers, an avalanche photodiode (APD) is provided, which receives the probe light beam via its corresponding saturable absorber due to the received light beam passing through this saturable absorber, and which does not receive the probe light beam via this saturable absorber due to the received light beam being absorbed by this saturable absorber. And an optical power read out means detectswhether or not probe light is received by each of the APDs which correspond to the saturable absorbers, thereby determines for each one of the saturable absorbers whether or not the received light beam has passed through it, and thus reads out the optical power of the received light beam.
