A method serves to optimize the behavior of an electronic force-measuring device, in particular a balance that comprises a measuring transducer through which a measuring signal is formed which is representative of a load applied to the force-measuring device, which measuring signal is delivered to a signal-processing unit that is supported by at least one processor and at least one memory storage unit and serves to process digital signals. First characteristic traits for the condition of the force-measuring device are determined, the first characteristic traits being the result of internal and/or external factors affecting the force-measuring device, and/or second characteristic traits for the force-measuring device are determined from the analysis of at least one signal profile of the measuring signal, whereupon the condition of the force-measuring device is determined on the basis of the first and/or second characteristic traits, and the further processing of the measuring signal and/or the operation of the force-measuring device is controlled accordingly. Based on the condition of the force-measuring device that was determined, the processing or evaluation of the signal as well as the use of optimizing measures that serve to determine, e.g., optimized correction parameters such as drift parameters or filter parameters can be advantageously controlled.

Method of optimizing the behavior of a force-measuring device, and force-measuring device

The output signal from a measuring transducer in a force-measuring device is processed by filtering a measuring signal (ms), representing a load that is acting on the transducer, to suppress interfering signal portions caused by extraneous influences including mechanical disturbances, or changes of the load. The measuring signal (ms) passes through a first delay element (A) to a measurement value unit () which holds the value of the currently received measuring signal (ms), a mean value based on the most recent values of the measuring signal, or an expected value (ms) based on the most recent values of the measuring signal. The measuring signal (ms) is monitored for signal disturbances using a first detector module (). After detection, a switching means () is actuated and the output signal (ms) of the measurement value unit is processed further, if applicable, and sent to the output end of the device, instead of the currently received measuring signal (ms).

A process for the image sharpening of a photographic image with a multitude of image elements is disclosed, wherein a correction mask for the change of the image sharpness is determined from the image data representing the image to be corrected, whereby the elements of the correction mask for the change of the image sharpness locally describe the degree of contrast change to be carried out for the individual image elements, and whereby additional information relating to the image is used for the determination of the elements in addition to information on the local contrast.
