A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
A finite-state transducer (FST) is a finite-state machine with two memory tapes, following the terminology for Turing machines: an input tape and an output tape.This contrasts with an ordinary finite-state automaton, which has a single tape.
The output of the generator is fed to a transducer in a half-inch cavity into which the sound level meter microphone is inserted. The sound level generated is 94 dB, which corresponds to a root-mean-square sound pressure of 1 pascal and is at a frequency of 1 kHz where all the frequency weightings have the same sensitivity.
Some displacement sensors are based on displacement transducers, [2] devices which convert displacement into another form of energy. [ 3 ] Displacement sensors can be used to indirectly measure a number of other quantities, including deformation , distortion, thermal expansion , thickness (normally through the combination of two sensors ...
Sonar systems are generally used underwater for range finding and detection. Active sonar emits an acoustic signal, or pulse of sound, into the water. The sound bounces off the target object and returns an echo to the sonar transducer. Unlike active sonar, passive sonar does not emit its own signal, which is an advantage for military vessels.
In a Facebook post Tuesday night, the George County Sheriff's Office urged the public to be cautious. "He will be desperate and very very dangerous. Call your family and alert them. Send messages ...
He signed a four-year, $15.5 million contract as a rookie. He's since developed into one of the NBA's most versatile big men and an anchor for the Rockets at 22 years old. In 63 games last season ...
Capacitive micromachined ultrasonic transducers (CMUT) are a relatively new concept in the field of ultrasonic transducers. Most of the commercial ultrasonic transducers today are based on piezoelectricity. In CMUTs, the energy transduction is due to change in capacitance. CMUTs are constructed on silicon using micromachining techniques.
