Sample disks are excised from a membrane by a cutting apparatus that includes a cutting tool terminating in a hollow cylinder with an exposed cutting edge, the tool slidably retained within a sleeve or otherwise slidably mounted to a mounting body, with a spiral cam in either the tool or the mounting body. The private wireless network includes a private base transceiver station, a private mobile switching center, and a gateway service control point. The protective film of a single layer type has an internal stress of \u221250 MPa to +60 MPa in the whole of the protective film. For each feature of the feature vector, the object search system uses the hierarchical clustering of objects to identify the cluster of objects that is most \u201cfeature similar\u201d to that feature of the target object. The application scheduler then applies the at least one policy to the usage information to determine whether policy violations exist.
