A multipurpose hemofiltration system (10) and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system (10) continuously monitors the flow rates of drained fluid, blood, and infusate. When necessary, the pumping rates of the infusate, drained fluid and blood are adjusted to remove a preselected amount of fluid from the blood in a preselected time period. A supervisory controller (160) can monitor patient parameters, such as heart rate (120) and blood pressure (130), and adjust the pumping rates accordingly. The supervisory controller (160) uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller (162) corrects temporal variations in the flow rate based upon an adaptive law and a control law.

In the motion estimation and compensation process for video frames, blocks O of pixels are considered. A number k of bit planes in a block O in a video frame F are compared with blocks O^R in reference frames (F^R). The best matching block (O^RM) is determined in the reference frames (F^R). Subsequently, a weight value (W_x^ij) is calculated for the best matching block (O^RM) based on the ratio of valid pixels therein. The residual pixel values (V_x^ij) extracted from the best matching block (O^RM) and corresponding weight values (W_x^ij) are stored in a pixel prediction array (120). The pixel array is used for motion compensation of at least the luminance component of valid pixels. Invalid pixels are reconstructed from surrounding pixel values.

A method of achieving automatic learning of an input vector presented to an artificial neural network (ANN) formed by a plurality of neurons, using the K nearest neighbor (KNN) mode. Upon providing an input vector to be learned to the ANN, a Write component operation is performed to store the input vector components in the first available free neuron of the ANN. Then, a Write category operation is performed by assigning a category defined by the user to the input vector. Next, a test is performed to determine whether this category matches the categories of the nearest prototypes, i.e. which are located at the minimum distance. If it matches, this first free neuron is not engaged. Otherwise, it is engaged by assigning the matching category to it. As a result, the input vector becomes the new prototype with the matching category associated thereto. Further described is a circuit which automatically retains the first free neuron of the ANN for learning.
