Abstract: A computer based system and method for implementing a read-modify-write operation in a computer based system comprising a first bus and a second bus, wherein the second bus is not transaction based. The method includes the steps of determining whether a first device connected to the first bus has issued on the first bus a read transaction comprising a predetermined trigger address, acquiring the second bus in accordance with the determination, reading data via the second bus from a second device connected to the second bus after the second bus has been acquired, modifying in a predetermined manner the data read from the second device, writing the modified data to the second device via the second bus, and releasing the second bus after the modified data has been written to the second device via the second bus.

Abstract: Automatic rain gauges (P00-P0n) are employed within the area of terrain (ZT). A meteorological radar (R1) provides, with a given radar periodicity, a radar image representing rain-bearing cells of concern to the area of terrain. By analyzing the succession of radar images, the main rain-bearing cells are tracked dynamically by their shape and motion. Then a radar rainfall measurement chart is compiled by accumulating, in each pixel of the area of terrain, the precipitations due, during a second chosen time interval, to these main rain-bearing cells, with interpolation of their shapes and positions. At least one sub-array (PA, PB) of four rain gauges separated from one another by about 2 to 4 kilometers and affected by at least one main rain-bearing cell is selected. Finally, the rainfall measurement chart is corrected at least partially as a function of the relation between the accumulated true rainfall data and those from the said chart at the locations of the rain gauges of the sub-array.

Abstract: Systems for performing peritoneal dialysis having an improved user interface functions and monitoring capabilities. In one respect, the systems discriminate between alarm conditions that require user intervention to correct and alarm conditions that reflect conditions that are anomalies but typically correct themselves with minimum or no user intervention. In another respect, the systems identify occluded liquid flow paths and discriminate whether the flow path is associated with a liquid source or a liquid destination.

Abstract: A computationally efficient and accurate procedure for calculating electron beam dose within a volume of a patient incorporating knowledge about the variations in density of the patient as obtained from a CT machine or the like employs an iterative process of dividing the patient into a set of layers of elements where each layer is computed from the previous layer by algebraic approximations of the Fermi partial differential equation. Energy loss of the particles is accommodated through the addition of a simple functional relationship between depth and energy or by separately binning energy at each layer as determined by local energy loss.
