An attribute-based component programming system and methodology for object-oriented languages is described. A description is also given of its use for the production of scalded-meat emulsion sausage, raw sausage and cooked ham. The welding current and voltage are measured on a series of repeated representative welds. The frame is formed by stamping a metal sheet or plastics injection molding. The feedback signal is provided to the secondary RF device. The base station protocol entity further comprises a control plane entity supporting an extended control plane for control plane signalling messages comprising specific control messages handling means, adapted to provide a specific probing or information control message and to send said message to a mobile user station.
