Abstract: In the framework of the method for minimizing the error of a measured variable, particularly a signal to be measured using filtering at variable bandwidth, the bandwidth is regulated on the basis of a physical criterion inherent to the method in such a ways that signal changes not caused by noise are recognized as early as possible.
Abstract: There is provided a system and methods for segmenting datapath resources such as reorder buffers, physical registers, instruction queues and load-store queues, etc. in a microprocessor so that their size may be dynamically expanded and contracted. This is accomplished by allocating and deallocating individual resource units to each resource based on sampled estimates of the instantaneous resource needs of the program running on the microprocessor. By keeping unused datapath resources to a minimum, power and energy savings are achieved by shutting off resource units that are not needed for sustaining the performance requirements of the running program. Leakage energy and switching energy and power are reduced using the described methods.

Abstract: There is provided an hydraulic reeling-in device for a water-transmitting, flexible hose, having mounting elements, a hose reel, an hydraulic driver kinematically connected to the hose reel, a water inlet connectable to a water-supplying pipe line and a water outlet provided with a connector for the hose. There is further provided a valve having two positions, a first position in which the water is permitted to pass from the water inlet through the water outlet into the hose, and a second position in which water is permitted to pass from the water inlet to the hydraulic driver in order to reel-in the hose, and a tubular member adapted, in the second position of the valve, to conduct water to the hydraulic driver.
Abstract: The invention relates to an image-processing method for automated contrast modification of digital image data. At least one low and one high-frequency signal are formed based on the digital image signal of the image data; the low-frequency signal component is modified using a characteristic-curve function; and then the modified, low-frequency signal is again added to the high-frequency signal component. In order to prevent the occurrence of distracting artifacts, so-called “halos”, the formation of the low-frequency signal component to be modified is formed in dependence upon the high-frequency image components.
