Abstract: With a method for compressing a dynamic range of an image, an original image signal Sorg representing an original image is processed, and a processed image signal Sproc representing an image having a narrower dynamic range than the original image is thereby generated. The method comprises the steps of calculating the value of an unsharp mask signal Sus corresponding to each of picture elements in the original image by averaging the values of image signal components of the original image signal Sorg, which image signal components represent the picture elements belonging to a predetermined region surrounding each picture element. Values of the processed image signal Sproc are calculated with the formula 
 
       Sproc = Sorg + f1(Sus)           
 
 where f1(Sus) represents a function, the value of which decreases monotonously as the value of the unsharp mask signal Sus increases. Alternatively, in lieu of the function f1(Sus), a function f2(Sus) is employed, the value of which decreases monotonously as the value of the unsharp mask signal Sus increases, and the differential coefficient of which is continuous.

Abstract: In potentiometric transmitters, signal interruptions of the potentiometer current occasionally occur. These signal interruptions can be avoided if care is taken that the slider current (Is) picked up at the potentiometer output (S) remains less than one microampere. So that an appropriate evaluation can occur in the control device, the slider current is amplified to about 40 microamperes in an interposed amplifier device. The amplifier device is usually arranged in the vicinity of the potentiometer, for example on an adapter plug which is plugged onto the potentiometer housing.

Abstract: When a relationship between a factor and a conclusion has occurred, data indicative of this relationship is stored in a case-history file. For example, in an apparatus which uses approximate reasoning to perform fault diagnosis, the type of a fault and its symptoms are recorded (in a repair report, maintenance report or the like) when the fault occurs. A knowledge base is revised or created by such case-history file data. The possibility of a conclusion, static information quantities, clarity of a conclusion, etc., are computed based upon such a knowledge base.

Abstract: The present invention relates to a method and apparatus for improving quality and increasing syrup yield within a typical beverage proportioning system (50). The invention controls the proportional blending as a function of the mass flow of the components input to the proportioner (50). The mass flow determination is made by Coriolis-type mass flow meters (54, 60) positioned within the feed lines (52, 58) for the water and syrup, respectively. From this mass flow determination an adjusted volumetric flow value for each component is determined by a master controller (68). The ratio of the calculated volumetric flow of the water to the syrup is used to determine a signal to control the proportional blending. The controller (68) sends a signal to an actuator (70) which adjusts a valve (72) for the water flow into the blending portion of the proportioner (50). The controller (68) also determines the accuracy of the adjustement and the efficiency of the overall blending and proportioning system.
