CDMA radio-communications procedure with access codes and pertinent receiver. The present invention determines the leakage by calculating a ratio between a measured flow of gas and a determined flow of gas related to a standard leakage. These MOSFETs include HTc superconductor material at operating temperatures. Accordingly, the seat belt is slowly wound up so that the tongue is less likely to strike and thus scratch an interior panel. The speed constant input may be varied under software control in order to determine the speed constant value that optimizes performance of speed-compensating circuits under SLL control. The compressed binary schema representation provides savings in bandwidth and processing requirements as compared to textual schema representations.
