An analyzer for diagnosing pulmonary and abdominals including, a pulsed force generator for outputting a mechanical disturbance to generate vibrations and reflected/return waves/vibrations in a patient's torso, and sensors for detecting the vibration/return wave signals. The apparatus compares the detected electrical signals with pre-stored reference wave profiles and based on the compared data generates an output signal indicative of a potential presence or absence of a pulmonary disease and/or condition.

A method for ultrasonic imaging a volume behind a barrier includes placing an array of elements of a probe adjacent the barrier. The local thickness and the sound speed in the barrier are estimated. A plurality of sub-apertures are defined in the array of elements, each sub-aperture defined by a different sub-set of adjacent ones of the array of elements. Ultrasonic waveforms are collected from each of the sub-apertures by focusing each sub-aperture approximately at the inner surface of the barrier. The ultrasonic waveforms through each of the sub-aperture elements are combined to generate a combined A-mode waveform. A profile of an inner surface of the barrier adjacent the probe is extracted based upon the combined A-mode waveforms. A correction is calculated based upon the profile of the inner surface. The volume behind the barrier is scanned using beamforming based upon the correction to generate an image of the volume.

The present invention providing a real-time positioning ultrasonic system that locates the dental implant drill bit relative to placed reference points or fiducial markers, and guides the drill entry point and angular trajectory, so that drilling is effected in the most optimum location in the jaw bone, as planned based on pre-surgery cone-beam computed tomography scans.

A method is provided for assessment of quality of an adhesively-bonded lap joint, wherein the joint includes a first metal plate, a second metal plate and an adhesive therebetween. The method includes sending ultrasonic waves normally to the surface of a sample outside of the joint where the sample has a first sample metal plate with the same properties as does the first metal plate at an assessment point of the joint. Reflected waves from the sample joint as a reference waveform are recorded. Wideband ultrasonic waves are sent normally to the surface of the joint at the assessment point. Reflected waves of the ultrasonic waves from the joint are recorded. A waveform of the reflected waves from the joint and reference waveform are analyzed to determine an informative parameter. The informative parameter is compared with a threshold value to assess quality of the joint.

A method and apparatus is disclosed for slow wave sleep improvement. The method includes recording a biosignal from a skin area of a patient using an electrode system. The slow wave stage of NREM sleep is detected by analyzing an oscillation rate of the biosignal. If the slow wave stage is detected, threshold electrocutaneous stimulation is applied to improve the quality of sleep. The described embodiment relates to an apparatus for slow wave sleep improvement comprising an electrode system, a measuring unit, a therapy unit and a processor. The processor is coupled to the measurement unit for receiving the biosignal corresponding to the electrodermal activity. The processor proceses the biosignal to determine the slow wave sleep stage and activates the therapy unit to deliver threshold electrocutaneous therapy to the patient with the purpose of improving the slow wave sleep stage.

A method and apparatus for ultrasonic in-process monitoring and feedback of resistance spot weld quality uses at least one transducer located in the electrode assembly transmitting through a weld tip into an underway weld. Analysis of the spectrum of ultrasonic waves provides the operator with an indication of the size, thickness, location, dynamics of formation and quality of the spot weld. The method presents a fundamentally new physical approach to the characterization of the spot weld quality. Together with transmission mode it includes new modes of operation of ultrasonic probes such as a reflection mode and simultaneous use of transmission and reflection modes, and a new physical interpretation of the signal analysis results.
