A hybrid engine and battery generator and a method of operating the same. The proposed technique operates by transmitting a wide-band signal over multiple, single-carrier, parallel transmission subbands, which may occupy non-contiguous frequency regions. The zoned garment optimizes evaporative cooling and wicking zones of a garment based upon a sweat profile and contact profile of the wearer. A firing mechanism including a piezoelectric actuator fires the projectiles in timed relationship with the rotation of the member so as to position the projectiles as required for balancing. If the network does not recognize the special identifier, no data channel is established. The digital single chip camera include a DA converter for converting an input digital word into an analog reference signal.
