Abstract: An apparatus and method for detecting battery removal, battery absence, and/or defective battery condition for use with battery charging and testing systems is provided. The apparatus includes a regulator, feedback module, controller, and detector module. The regulator and feedback module supply a regulated charging signal to a battery. The controller interrupts the feedback module so as to cause the regulator to suspend supplying the charging signal to the battery, which in turn, allows the charging signal to discharge for a predetermined period of time. During the predetermined period, the detector module detects whether the charging signal discharges below a predetermined threshold. When the charging signal discharges below the predetermined threshold, the detector module detects one or more conditions that indicate that the battery cannot be charged. These conditions include conditions that indicate that the battery is absent, missing, and/or defective.

An indicator indicates when a frequency has been selected outside of the defined range. The device is preferably implemented as a complex programmable logic device (CPLD).

Abstract: An automatic drive circuit for an ultrasonic probe, such as a dental scaler insert, is operative with a probe which includes a magnetostrictive unit and a vibratory element to be set into vibration by the magnetostrictive unit upon energization of the magnetostrictive unit with an alternating magnetic field. An energizing coil is enclosed within a handle having a compartment for receiving the probe. The coil is located within the handle adjacent to the probe-receiving compartment for applying the alternating magnetic field to the magnetostrictive unit upon insertion of the probe into the handle and upon energizing the coil by the drive circuit. An oscillator of the drive circuit is coupled to the coil for applying an oscillatory current to the coil. The drive circuit includes a frequency sensor for sensing a frequency of the oscillatory current, the sensor outputting a signal designating a magnitude of the frequency. A further component of the drive circuit establishes a value of amplitude of the alternating current in response to the sensed value of the frequency. The circuitry relies on the inductance introduced via the magnetostrictive unit to the coil for automatically establishing the value of oscillation frequency commanded by the probe.

Abstract: In a switching voltage power supply, a series regulator circuit interconnects an input voltage section with an output voltage section of the switching power supply. The regulator circuit has an n-channel MOSFET transistor serving as a regulator element. A gating circuit applies a gating voltage to the gate terminal relative to the drain terminal for establishing states of current conduction and current cut-off in the transistor. A biasing circuit interconnects the gating circuit with the drain terminal for establishing an offset potential of the gate terminal relative to the drain terminal during the state of current conduction, the offset potential counteracting a gate-to-source threshold voltage for reduction of a voltage drop between the drain terminal and the source terminal with a corresponding reduction in power dissipation of the regulator element.
