A method for machining components which do not contain magnetic material is provided. A central authority having a central authority private key Ksca assigns a customer account to the customer and a merchant account to the merchant. To load the porous surface with a biologically active agent or drug, an electrophoresis method is employed. In yet another embodiment, capture phases for LBIST testing may be made to be asynchrounous within each capture phase, such that data capture for one LBIST partition may be timed different from other capture phases for other LBIST partitions. An assurance tool of migration strategies is provided for tracking changes and avoiding conflicts between the enhancement and the model and production software systems. The programmable logic device receives temperature data from the temperature sensing array and structure-borne noise data from the vibration sensing array.
