A sensor bearing assembly for supporting a rotatable shaft includes a bearing having an inner ring disposable about the shaft, an outer ring disposed about the inner ring, and rolling elements between the rings. The system includes a release valve having a side opening for release of water collected therein. When performing the preliminary extracting and index processing the invention establishes a window grid for the circuit design and merges basis patterns with shapes in the circuit design within each window of the window grid. A magnifying lens is carried by the coupling member and is located intermediate the upstream and downstream ends of the coupling member. In D=B\u2212C, Q is a quotient of BC if C<D or a quotient of BD if C>D.
