|20110034818||METHOD AND SYSTEM FOR QUANTITATION OF RESPIRATORY TRACT SOUNDS - Provided is a system and method for analyzing respiratory tract sounds. Sound transducers are fixed on the skin over the thorax that generates signals indicative of pressure waves at the location of the transducer. Processing of the signals involves performing an event search in the signals and determining event parameters for events detected in the search.||02-10-2011|
|20110021933||Methods and Systems for Use in Determination of a Patient's Heart Condition - A method and system are presented for use in monitoring a subject's heart conditions such as ejection fraction and cardiac synchrony. For determination of the ejection fraction, ECG measured data is processed. This ECG measured data comprises a first measured data portion indicative of a first time profile of an electrical signal measured on a planar pair of electrodes applied on a patient during a measurement session and a second measured data portion indicative a second time profile of an electrical signal measured on a diagonal pair of electrodes applied to said patient during said measurement session. The processing comprises comparing the first and second data portions to identify a time shift between a predetermined event in the first and second time profiles. For the determination of heart synchrony, first and second measured data portions corresponding to respectively an ECG measurement and an acoustic measurement both obtained from a patient during the same measurement session of a duration including at least two cardiovascular cycles, are processed. Such processing comprises identifying predetermined first and second events in each of said at least two cycles in the first and second measured data portions, respectively, determining a relation between the first and second events for each of the at least two cycles, determining a degree of fluctuation of said relation in the at least two cycles.||01-27-2011|
|20090326418||MICROPHONE MATRIX FOR RECORDING BODY SOUNDS - The invention provides a microphone matrix for recording body sounds, such as respiratory tract sounds. The matrix has a frame having one or more recesses or openings on one of its surfaces. A microphone assembly is disposed in each recess or opening in the frame. When a body portion is applied to the matrix, each microphone assembly moves from an extended, spring biased position in which at least a portion of the microphone assembly protrudes beyond the surface of the frame towards a retracted position in which the microphone assembly is deeper inside the recess.||12-31-2009|
|20080281219||Method and System for Assessing Lung Condition and Managing Mechanical Respiratory Ventilation - The present invention discloses a novel non-invasive, bedside system and method to monitor parameters associated lung changes. A novel approach for monitoring the operation of the respiratory system of a subject is provided. There is also provided a method for objectively evaluating the benefit of one mode of ventilation over another, and for assessing the differences in regional lung vibration during different modes of mechanical ventilation. The method comprises recording one or more signals from the subject, the signal varying in time according to operation of the respiratory system; and; processing the recorded signals to obtain a predetermined functional thereof presenting one or more time-varying energy functions of the subject, an abnormality in the one or more energy functions being indicative of a suspected abnormality in the operation of the respiratory system. The signals may be acoustic signals recorded by a plurality of acoustic sensors placed over the subject's thorax or back, and the at least one time-varying energy function is obtained from one or more specific regions of lung or by summing/averaging the time-dependent acoustic signals of the plurality of sensors indicative of the whole lungs.||11-13-2008|
|20080221467||Method and systms for regional assessment of pulmonary function - A method and system for regional assessment in two or more regions of an individual's lungs. The system includes a plurality of transducers configured to be fixed over the thorax. Each transducer generates a signal P(x||09-11-2008|
