Claim:
1. An ultrasonic transmitter having adjustable output amplitude, comprising: a carrier oscillator that generates first acoustic signals and second acoustic signals at a frequency; a power driver having an input coupled to the carrier oscillator, wherein the power driver amplifies the first acoustic signals having the frequency and the second acoustic signals having the frequency; and an acoustic transducer coupled to the output of the power driver, wherein the acoustic transducer transmits the first acoustic signals having the frequency and a first amplitude at a first time, wherein the acoustic transducer transmits the second acoustic signals having the frequency and a second amplitude at a second time, wherein the first amplitude and the second amplitude are determined by the power driver, wherein the first amplitude is set during installation, and wherein the second amplitude is regulated at the second time, wherein the second amplitude of the second acoustic signals are generated based on an adjustment to a setting between the first time and the second time.
