The present invention relates to the identification of macaque antibodies to human B7. The fluid flow path may include a longitudinal passage in the spindle disposed generally along the longitudinal axis. A determining unit estimates the accuracy of the predictive vector generated by the prediction error generating unit based on the degrees of non-uniformity of the motion vectors of the plurality of adjacent blocks. In a second embodiment the interface board includes test pads in electrical communication with the test circuitry, and slidable test contactors having beam leads configured to simultaneously engage the test pads and the terminal contacts on the module.
