Abstract: An ultrasonic surgical instrument includes a housing, a waveguide extending distally from the housing, an end effector coupled to the distal end of the waveguide, an ultrasonic transducer retained within the housing, and a controller. The ultrasonic transducer is coupled to the proximal end of the waveguide and configured to produce mechanical motion for transmission along the waveguide to the end effector. The controller is configured to control an amplitude of the mechanical motion of the ultrasonic transducer in accordance with at least one amplitude value. The at least one amplitude value is adjusted according to an age of the ultrasonic transducer to compensate for aging of the ultrasonic transducer. Methods for controlling the amplitude of the mechanical motion of an ultrasonic transducer to compensate for aging of the ultrasonic transducer are also provided.

The piston (31) is driven by the vibration exciter to move in a sinusoidal manner in the cavity (35) of the airtight infrasound generating chamber (3) and the standard infrasonic pressure signal with low harmonic distortion can be achieved. The displacement of the moving part (22) of the vibration exciter (2) can be measured by the laser vibrometer (1) through the measurement beam (15) injecting into the vibration exciter (2) through the optical channel running through the vibration exciter and the standard infrasonic pressure can also be obtained. The value of the standard sound pressure produced by the infrasound generating chamber is calculated. Such value is used as the calibration reference for the infrasound sensors (4) to be calibrated in order to achieve the primary calibration of the infrasound sensors. The standard infrasonic sensor can be installed inside the infrasound generating chamber (3) and the output of the standard infrasonic sensor can be used as the reference for the infrasonic sensor (4) to be calibrated in order to achieve the secondary calibration of the infrasound sensors. This invention has the advantages of technical maturity, high feasibility, easy to realize, high calibration accuracy and so on.

Abstract: Method, apparatus and computer programs are described for compensating for the effect of temperature on the sensitivity of electrostatic ultrasound (US) transducers, particularly as used in an automotive occupancy sensing (AOS) systems for sensing the nature or type of occupant and the location of the occupant with respect to the vehicle interior. The invention permits the AOS to classify the occupancy state of the vehicle from a US echo signal substantially free of the effects of temperature on signal amplitude. A capacitive divider or voltage monitor is employed to measure the capacitance of the transducer. The voltage monitor output is used by the scaling algorithm of a compensator to determine the scaling factor to be applied to the US transducer signal to compensate for the effect of temperature on the transducer sensitivity. Calibration procedures and software are disclosed for determining the coefficients of the scaling algorithm to compensate for temperature effects and also to compensate for installation factors, transducer manufacturing variations, and circuit board effects. The system disclosed is useful for other types of signal processing in addition to temperature compensation of AOS ultrasonic signals, and may be used in other ranging devices such as cameras, golf or binocular range finders, and measuring devices and instruments.

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: A system and method for tuning and controlling ultrasonic handpieces by incorporating a broad-spectrum signal as at least a component of the signal used to drive the handpiece. The response of the handpiece to this broad-spectrum signal is measured and the frequency or amplitude or both of the drive signal are adjusted in order to maintain the desired level of handpiece performance. The operation of the systems and the performance of the methods described enables the handpiece to be operated in a most effective manner over a more widely varying range of mechanical load and thermal conditions than was possible through the use of prior control systems and methods.

Abstract: An ultrasonic aerosol apparatus having a piezoelectric element which generates ultrasonic signals in response to signals received from an oscillating circuit, where the temperature of the piezoelectric element is controlled by an electronic device such as an N.T.C. thermistor. The temperature control device senses the temperature of the piezoelectric element and controls the power fed to the oscillator circuit in accordance with the temperature of the piezoelectric element. Rather than cut power completely to the oscillator circuit (thereby interrupting the atomization process of the apparatus), the temperature control device reduces power fed to the oscillator circuit when the piezoelectric element temperature rises above a predetermined value, and increases power fed to the oscillator circuit when the piezoelectric element temperature falls below a predetermined value. Leakage of liquids (e.g., water or medication) contained within the apparatus is avoided by the lack of joints in the liquid-holding apparatus containers. The piezoelectric element may be ceramic, and may be supported by an elastic element which itself may act as an electrical connection between the piezoelectric element and the temperature control device.
