The apparatus for inputting coordinates has a support plate including a coordinate input plane for inputting a coordinate position, an optical unit is formed by integrating a light source and a light receiver. The ductile layer provides a favorable load distribution through the composite at the attachment location, and eliminates the need for a metallic shim. The script comprises at least one command describing an event comprising a data value. The pivoting member is formed of a connector, a washer, a locating tube, and a spherical joint. The packaging is advantageous in that different positioning of the holding element enables large anti-friction bearings with different diameters to be received therein. Helical auger plug systems may comprise a removably attachable flag to indicate when the plug member is in use.
