    Abstract: A dental scaler comprises a hollow sleeve and, arranged inside it, a vibrating piezoelectric transducer bearing a scraper, the extremity of which protrudes from the sleeve, and includes an amplifier connected to the transducerk. The transducer includes a base, of a series of piezoelectric chips on the surfaces of which are arranged electrodes connected in such a manner as to define an input and an output, and a head to which the scraper is coupled. The amplifier has an input, an output and two feeder terminals receiving a low direct voltage by way of a cable connected to an external source of voltage. The output and input of the transducer are connected, respectively, to the input and the output of the amplifier to form an oscillator, the frequency of which is determined by the resonant frequency of the transducer coupled to the scraper.

    Abstract: A method of and system for sonifying a portion of a given area to rid the area of unwanted pests comprising providing at least one ultrasonic point source each producing a set of pulsed signals having a randomly varying frequency in the range of about 18-30 KHz and having an intensity of at least 90 dB at the periphery of a cone shaped area extending outwardly therefrom and having a predetermined maximum length and a predetermined maximum width. The point sources are spaced in the given area to maintain the minimum sound intensity level at any point in the sonified portion at not less than 90 dB by disposing point sources opposite one another when the distance therebetween is greater the maximum length, disposing point sources adjacent one another to effect a longitudinal overlapping of adjacent cones when the room width is greater than the maximum width and disposing point sources perpendicular to the adjacent point sources to sonify any dead space therebetween.

    Abstract: The output of a single sonic generator is rotated to different transducers separately located on a diaphragm of a tank containing cleaning fluid. The rotating of the output to different transducers establishes a ripple action in the cleaning fluid to vary energy levels at any given location within the tank. The varying energy levels allows the gas formed within the fluid to rise to the top of the cleaning fluid in a process called degassing. Rotation of the output may be accomp lished by interrupting the output of the sonic generator and, while the output is interrupted, to switch the connection to another transducer. The switching of the output of the sonic generator from transducer to transducer varies the standing wave pattern, thereby allowing the gas to rise to the surface. The interrupting of the sonic output and the switching action are accomplished by specially designed solid state circuits to obtain optimum performance.

    Abstract: A capacitive micromachined ultrasonic transducer (CMUT) cell comprising three electrodes: a first electrode coupled to a cell membrane; a second electrode embedded into a cell floor opposing the first electrode and separated therefrom by a gas or vacuum cavity; and a third electrode opposing the second electrode on the cavity side, wherein a dielectric layer is sandwiched between the second electrode and the third electrode to create a capacitive relation between the second electrode and the third electrode. The three electrode CMUT cell provides an ultrasound transducer with two actively driven (controlled) electrodes.
