A face feature extraction apparatus and method are provided. The speakers have a first position for providing a substantially extended configuration and a second position for providing a substantially retracted configuration. The method further includes making at least one mark on the mask in relation to the defect; positioning the IC design layout over the mask thereby covering the defect by the IC pattern; and patterning the mask with the IC design layout. The summer is configured to sum the response signals from each fluxgate module into a summed signal. The first buffer is disposed between the first composite structure layer and the second composite structure layer and has a third thickness and a third dielectric constant. Efficient arrangements for efficiently increasing the density of computer configurations are shown, particularly when used in a network server or host environment.
