Abstract: A portable medical diagnostic ultrasound system is provided which includes shielding for electromagnetic interference by forming shielded enclosed compartments around the individual components of the ultrasound system. This compartmentalization of components isolates EMI between the components themselves as well as the outside world. Further, the EMI shielding provides structural rigidity and support for the entire ultrasound system. In another aspect, the EMI shielding provides heat dissipation capability for the internal components of the ultrasound system. The portable medical diagnostic ultrasound system further provides a transducer connector which provides high density interconnects between the transducer and the ultrasound system while providing an ergonomically easy to handle connector. Further, the connector is rugged, providing a high number of connection and disconnection cycles.

Abstract: For the drive excitation, the method for the capacitive drive excitation of oscillators in sensors for the capacitive measurement of force, acceleration and, in particular, rotation rates according to the Coriolis principle, provides according to the invention for the use of high-frequency constant-amplitude pulse packets with no DC component, the width or phase angle of which can be adjusted in order to keep the oscillator speed constant, for the purpose of resetting or correcting tolerances. As an alternative, the method may also be configured in such a way that, in the case of oscillators with pairwise excitation electrodes which are symmetrical with respect to the rotation axis, equal constant-amplitude HF voltages are applied, the frequency of which is chosen to be substantially higher than the natural frequency of the oscillator, in which case a particular resulting force of attraction on the oscillator is brought about by shifting the phase angle between the drive voltages and, in the case of rotation rate sensors working according to the closed-loop principle, system resetting can also be ensured. By virtue of the invention, problems with coupling the excitation signal into the read channel of a micromechanical oscillator system can be brought well under control.

Abstract: A relatively high voltage is developed across a buzzer by placing a resistance in the discharge path of an buzzer, e.g., by shunting one or more Zener diodes or LEDs across a switching transistor, the switching transistor being connected in series with the buzzer between a voltage potential and ground. Alternatively, the buzzer is shunted with a resistive element, with or without series connected a reversed biased diode. The result is a higher audio output without a corresponding increase in power consumption.
