The present invention provides a cardable fiber blend which forms a moldable fiber batt, the blend comprising fibers having a modulus of 550 gdenier or more with fibers of a thermoplastic polymer wherein the high modulus polymer fibers are all uncrimped fibers or a mixture of crimped and uncrimped fibers. The bills are folded based on denomination to allow the customer receiving the bills from the cash dispenser to be able to identify the denomination of each bill. The data packet transmission order, the coding scheme, andor the output power level may be determined, at least in part, by the temperature of the power amplifier, a quality of service associated with the data packets, a data packet length, andor a link budget. The position of the volume to be treated is visualized by the imaging device to monitor the progress of the treatment and to guide ablation treatment so as to mitigate collateral tissue damage. Other aspects of the teachings, the rear header may include a stop light that is mounted in the header or it may include a rear windshield wiper system. The local clock frequency of the slave clock is synchronised to the recovered frequency.
