Abstract: A device for generating high-frequency mechanical vibrations for dental purposes comprises a current detector (50) fitted in the supply line of a vibration generator (12). The output signal of the current detector (50) is transmitted to one of the inputs of a control circuit (74), which at its other input receives a supply current nominal value signal. The output of the control circuit (74) is connected to the control terminal of a controllable oscillator (42), which together with a power stage (46 to 48) prepares the supply current for the vibration generator (12). In this manner, a constant output amplitude of the vibration generator is obtained independent of the load coupled to said vibration generator at any given time.

Abstract: A vibrating mechanism comprised of piezoelectric elements which vibrate at a high frequency when a voltage is applied to them. The piezoelectric elements are mounted on a rib so that their free ends extend from the rib. When the piezoelectric elements are energized the free ends vibrate with a "wing-flapping" motion. Weights may be attached to the free ends of the piezoelectric element to increase the inertial component of vibration. In the preferred embodiment of the invention, the piezoelectric elements are prestressed. The invention will be an inexpensive substitute for other vibratory devices.

Abstract: The system uses a tunable inductor in series with the piezoelectric crystal excitation transducer in the probe which has a flux modulation coil. The bias current through this flux modulation coil is controlled by the system. It is controlled such that the inductance of the tunable inductor cancels out the capacitive reactance of the load impedance presented by the probe when the probe is being driven by a driving signal which matches the mechanical resonance frequency of the probe. The resulting overall load impedance is substantially purely resistive. The system measures the phase angle and monitors the power level. The system uses this information to adjust the bias current flowing through the flux modulation coil to maintain the substantially purely resistive load impedance for changing power levels. This information is also used to adjust the frequency of the driving signal to track changing mechanical resonance conditions for the probe at different power levels. This method of operation insures substantially maximum power transfer efficiency and substantially linear power control over a range of power dissipation levels. There is also disclosed an analog circuit to measure the phase angle for the load driving signal and to adjust the frequency of the driving signal for best performance. This system includes an integrator to eliminate the effect of offset errors caused by operational amplifiers. There is also disclosed a system to determine the mechanical resonance frequency by sweeping the drive frequency and monitoring the drive current for the frequency at which the drive current is a maximum.

Abstract: An ultrasound generator and emitter suitable for use in ultrasound therapy has an electrical signal generator for charging an ultrasound resonator in an ultrasound head with electrical signals, which are converted into ultrasound energy to be emitted. The ultrasound head also includes an adapter element which electrically matches the particular ultrasound head being used to the electrical signal generator. The adapter is in the form of a removable adapter element which is electrically matched to the ultrasound resonator. The adapter element can be easily plugged into and removed from a circuit board in the ultrasound head. When the ultrasound resonator is replaced, the adapter element can be easily interchanged with an adapter element for matching the new ultrasound resonator to the signal generator.

Abstract: An Ultrasonic Piezoelectric Transducer for atomizing fluids oscillates at its free natural vibration in a parallel resonant circuit. Very short energy pulses are transmitted into the parallel resonant circuit to maintain continuously the free vibration. The measuring the time dependant voltage of the transducer, the transducer vibration frequency is tapped off to regulate the supplied pulses and to transmit them in proper phases. Thus, optimal atomizing is guaranteed in spite of changing operating conditions.
