A composite printed wiring board includes a parent board and a child board that is mounted on the parent board. In an embodiment, the transmitting unit generates a spark gap which generates an ultrasonic vibration either on the surface of, or within, the test object. Next, a dense dielectric spacer is formed in the at least one opening and at least partially on exposed sidewalls of the dielectric material. The plasma processing system further includes a first set of nozzles coupled to the gas flow control assembly and configured to supply a first set of gases for processing a first portion of the substrate. In a mobile environment like in UMTS the idea could be implemented by using IP multicast for efficient transmission in the IP network between the SEGSN and GGSN for example on the Gn interface. The image and map data is scanned for traffic-relevant information and compacted to relevant image and map data in a first and second scene interpretations, and the relevant image and map data is supplied to a rule engine and to a state machine for interpreting the image and map data.
