Improved apparatus for imprint lithography involves using direct fluid pressure to press a mold into a substrate-supported film. Accordingly, the ambient temperature is sensed by the temperature control circuit and is fed back to control the rotation rate of the motor. Therefore, machine to machine communication is emerging as an important application of a communication network. After that, the current setting is compared with the current, measured ambient sound level and a corresponding control signal is output dependent on the result of the comparison. Two documents may be considered to be near-duplicates if any one of their fingerprints match.
