A sensor structure having a metallic terminal member. The hydroxypropyl-sulfobutyl-&bgr;-cyclodextrin is a derivate of cyclodextrin which is substituted by hydroxypropyl group and sulfobutyl group: n–m–&bgr;-cyclodextrin. For lower doses of implanted gallium, the transmission is restored to 100%, although the thickness of the substrate is reduced. When the ray is moved, a second ray-surface intersection can be found by finding a polygon locally near the first intersection and containing a first intersection with the moved ray, traversing out from the local polygon through adjacent polygons intersected by the moved ray, and determining whether traversed polygons are unoccluded based on whether they are part of the convex hull surface. In addition, since the CCD output level obtained when the storage time is set to be the same as that set at the time of scanning can be predicted, the illumination intensity of the lamp can be obtained by calculating an output level at which no saturation occurs in that situation. A computing resource configured to run the conditional access protocol has a smart card interface and a software wrapper configured to run on the computing resource coupling the smart card interface to the conditional access protocol.
