- An alternating current oscillating at ultrasonic frequency is applied by a separate power supply unit to the piezoelectric transducers.
- In 1945, Gordon D . Forbes and Herbert Shapiro filed a patent for the a mercury delay line with piezoelectric transducers.
- One type of piezoelectric transducer is the Langevin type, named after a transducer used by Paul Langevin in early sonar research.
- In a tunable demultiplexer or OADM, the Bragg wavelength of the FBG can be tuned by strain applied by a piezoelectric transducer.
- During this scan, a feedback point is set so that the piezoelectric transducer can maintain constant signal intensity during the lateral scan.
- :: : The fogger that uses a 2Mhz ultrasound piezoelectric transducer is good for small scale ( about 0.5 square meters ).
- To fine-tune the frequency of the laser, a diode laser with a piezoelectric transducer that controls the cavity wavelength can be used.
- The SQS-23 sonar first used magnetostrictive nickel transducers, but these weighed several tons and nickel was expensive and considered a critical material; piezoelectric transducers were therefore substituted.
- The most common method for detecting the mechanical resonant spectrum is illustrated in Fig . 2, where a small parallelepiped-shaped sample is lightly held between two piezoelectric transducers.
- When acoustic instruments with resonant bodies are amplified with microphones and piezoelectric transducer pickups, the common approach used for amplified double basses, they are prone to have feedback problems.
- The electrical output from the photomultiplier tube is used as constant feedback to the piezoelectric transducer to adjust the height of the tip according to variations in surface topography.
- In 1938, Willia Spencer of Electrical & Musical Industries ( later EMI ) applied for a patent on an acoustical delay line using piezoelectric transducers and a liquid medium.
- During World War II, Cady again worked on military applications of piezoelectricity, including trainers for radar operators that used piezoelectric transducers in liquid tanks to generate realistic radar returns.
- The basic design of a photoelastic modulator consists of a piezoelectric transducer and a half wave resonant bar; the bar being a transparent material ( now most commonly fused silica ).
- Originally natural materials were used for the transducers, but by the 1930s sonar systems incorporating piezoelectric transducers made from synthetic materials were being used for passive listening systems and for active echo-ranging systems.
- In earlier columns Daedalus proposed attaching sensitive piezoelectric transducers, accelerometers and other instruments to dying people to detect the departure of their souls and to measure the soul's mass, velocity and quantum-mechanical spin.
- Thus the decay constant is found empirically and is used to interpret the signal obtained during the lateral scan and to set a feedback point for the piezoelectric transducer during constant signal scanning.
- The sensitivity of these devices continues to improve; a newly developed piezoelectric transducer can produce frequencies in the MHz that can easily propagate through even high acoustic impedance materials such as steel and dense ceramics.
- Also, since both piezoelectric transducers and microphones are more prone to unwanted feedback than magnetic pickups, the bass tech may have to set up a notch filter with a parametric equalizer to reduce the frequency that is feeding back.
- But that speaker is invariably the cheapest that it's possible to get ( it's often just a piezoelectric transducer, someones soldered directly to the motherboard ); so the sound quality was so bad it generally made Edith Piaf sound like a bad-tempered Dalek.
