Title: Method and system for reproducing monochromatic and color images using ordered dither and error diffusion
Inventor: CHAN CHOR S
IPC: H04N1/52
Filed: 1990-10-10
Granted: 1996-11-05
Abstract: A method  and  system  for  color  and  monochromatic printing wherein ordered dither and error diffusion processes are combined to provide high quality printed images with good spatial resolution,  good gray scale transitions,  good low frequency  and  high  frequency  responses  and  a  high computational speed.  Using this process, gray scale numbers representative a of scanned image are summed for each super pixel of the scanned image and divided by a chosen gray level normalizing factor. This division operation is done to obtain a normalized ordered dither quotient number of drops (dots) to be printed in super pixels and to further obtain an error remainder number of dots to be dispersed to surrounding super pixels.  The normalized ordered dither quotient number of dots are printed in pre-assigned individual pixels within printed super pixels, and the error remainder number of drops are diffused to other pre-assigned surrounding or adjacent super pixels.  In this manner, a combination of ordered dither and error diffusion signal processing and printing is achieved to simultaneously  take  advantage  of  some  of  the  best characteristics of both types of signal processing printing.       In color printing, the above operation is carried out in each of a plurality of separate color planes, and all of the  quotient  information  is  retained  and  printed  in  a predetermined priority sequence for each color plane.  Thus, this invention is not only operative to retain the maximum amount of image data for each color plane, but it is printed in an output matrix of super pixels in such a manner as to maximize overall print quality of the reproduced color image.

Title: Method and apparatus for determining full load condition in a screw compressor
Inventor: RENTMEESTER PAUL C
IPC: F25B1/047
Filed: 1990-12-04
Granted: 1993-03-23
Abstract: Title METHOD AND APPARATUS FOR DETERMINING FULL LOAD CONDITION IN A SCREW COMPRESSOR     Abstract The determination as to whether an operational compressor in a multiple-screw compressor water chiller is fully loaded is made by sending a relatively long duration test pulse to the load solenoid of the compressor.  If the compressor is fully loaded, no measurable change in the current drawn by the compressor motor will be measured since no slide valve movement will have occurred and no additional load will have been placed on the compressor.  If, however, the compressor is not fully loaded at the time the test pulse is sent, the compressor slide valve will move to load the compressor to an extent such that a reliably measurable change in compressor motor current draw occurs.

Title: Reverse osmosis system
Inventor: BIRDSONG THOMAS E
IPC: C02F1/44
Filed: 1991-01-11
Granted: 1996-10-01
Abstract: A reverse osmosis system includes a sediment filter which cleans feed water from a source and from which that feed water is fed to a reverse osmosis membrane filter. Permeate from the latter is fed to a bladder within a storage tank. Concentrate from the membrane filter is fed to and used within the storage tank as squeeze water for the bladder. When a faucet that delivers permeate to the user is open, squeeze water is used to cause permeate to flow out of the storage tank through an impurity filter to supply the faucet. A valve unit is included to control the amount of squeeze water fed to the storage tank and to regulate permeate flow so that the water outletted from the faucet remains at a constant pressure and provides relief as against overpressure in the system. A proportioning valve within the valve unit serves to maintain at all times a constant ratio of concentrate to permeate flow through the membrane filter for adequate cleansing of the membrane. Also included are input-side and output-side flow monitors which provide signals to a processor that serves to indicate the status of filter conditions. There also is an advantageous faucet assembly for controlling the delivery of permeate to the user with flexibility and convenience.
