    Abstract: A method for detecting loose blades in a hand piece connected to an ultrasonic surgical system by performing frequency sweeps of a drive signal through a range which includes the resonance of a hand piece/blade system and the resonance of the hand piece without a blade attached. The frequencies of resonance in each sweep are compared. If a substantial difference between the frequency sweeps occurs, then a "Tighten Blade" message is displayed on a liquid crystal display on an ultrasonic generator console. The method permits rapid and easy diagnosis of loose blade connections. The method also assists a surgeon or nurse in knowing when to tighten the blade, as opposed to performing more lengthy and detailed diagnostic or cleaning procedures. In addition, the time and costs associated with the diagnostic procedures to isolate faults are eliminated because, upon determining that the blade is not loose, the surgeon and/or nurse can request a new blade based on the assumption that the blade is broken.

    Abstract: Systems and methods for testing the performance of a focused ultrasound transducer array include transmitting ultrasonic energy from the transducer array (12) towards an acoustic reflector (18), such as a planar air mirror (18), and receiving ultrasonic energy reflected off of the acoustic reflector using a sensing element (20). A characteristic of the reflected ultrasonic energy, such as amplitude and phase, is measured by processing circuitry, for example, by comparing the characteristic of the received ultrasonic energy to a corresponding characteristic of the transmitted ultrasonic energy to obtain an actual gain and phase shift for the received ultrasonic energy. A controller compares the actual gain and phase shift of the received ultrasonic energy to an expected gain and phase shift of the received ultrasonic energy. This information is used to calibrate the transducer array and/or to declare a system failure if the comparison indicates an error.

    Abstract: The present invention pertains to a method of capacitive stimulation of an oscillator control in sensors used for capacitive measurement of strengh, acceleration and especially rotation speed based on the Coriolis principle. In this method, the control is stimulated using high frequency pulse packs, free of continuous voltage and constant in amplitude, of which the width or phase angle relative to the stabilized oscillation speed is adjusted for the purpose of resetting to the initial state or correcting tolerances. Another embodiment of the inventive method allows, in case of electrode oscillators installed in pairs and symmetrically relative to the rotation axis, for high frequency voltages to be obtained that are identical and constant in amplitude. The frequency chosen for these voltages is clearly above the oscillator frequency, resulting in a certain attractive force acting upon the oscillator by shifting the mutual phase lag in the control voltages. In the case of rotation speed sensors the setting of which is based on the closed-loop principle, a resetting to the initial state may also be ensured. The invention also enables problems related to coupling the stimulating signal in the selector channel of a micromechanical oscillator system to be overcome.
