An electrical connecting device for two electrical components which, when assembled, have electrical contact areas facing each other. The catheter includes a rigid tube adapted to engage a lithotripsy transducer and power supply, with a restriction in an internal diameter of the rigid tube proximate a power delivery end of the rigid tube. When a subscriber terminal is initiating the establishment of a connection to another network entity, the server means is adapted to transmit a subscriber-prepaid-account related value informing a control means on an available charge threshold value for the connection to be established. The silicide layer is disposed on the sourcedrain region, wherein the silicide layer includes a curved bottom surface. Additionally, one implementation uses a general purpose lookup engine that can traverse multiple tree bitmaps or other data structures simultaneously, and perform complete searches, partial searches, and resume partial searches such as after receiving additional data on which to search. The relay optical system is configured to form images of the light reflected from the mark formed on the substrate and the mark formed on the mold between the relay optical system and the detection system.
