20160095545 | METHOD AND SYSTEM FOR DETERMINING A PRE-MULTISYSTEM FAILURE CONDITION USING TIME INTEGRATED VOICE ANALYSIS - A method for diagnosing an impending multisystem failure in a patient, comprising steps of obtaining data of recorded speech of the patient, calculating an intensity function of the data across a plurality of frequencies, and determining the number of vibrations in the range of an octave in the recorded speech. A number of vibrations larger than four are indicative of an impending multisystem failure in the patient. | 04-07-2016 |
20160095571 | Infrasonic Stethoscope for Monitoring Physiological Processes - An infrasonic stethoscope for monitoring physiological processes of a patient includes a microphone capable of detecting acoustic signals in the audible frequency bandwidth and in the infrasonic bandwidth (0.03 to 1000 Hertz), a body coupler attached to the body at a first opening in the microphone, a flexible tube attached to the body at a second opening in the microphone, and an earpiece attached to the flexible tube. The body coupler is capable of engagement with a patient to transmit sounds from the person, to the microphone and then to the earpiece. | 04-07-2016 |
20160113618 | ACOUSTIC MONITORING TO DETECT MEDICAL CONDITION - Acoustic signals may be used to monitor one or more symptoms of a patient disease. A patient prescription may indicate one or more acoustic sensing programs that may be used to monitor at least on characteristic of an acoustic signal indicative of a patient symptom or disease. The patient prescription may also include a patient specific threshold. When the at least one characteristic of the acoustic signal is compared to the patient specific threshold an indication or warning signal may be generated. The warning signal may indicate a change in patient disease state. | 04-28-2016 |
20160135732 | SYSTEMS AND METHODS FOR USING ISOLATED VOWEL SOUNDS FOR ASSESSMENT OF MILD TRAUMATIC BRAIN INJURY - A system and method of identifying an impaired brain functionality such as a mild traumatic brain injury using speech analysis. In one example, recordings are taken on a device from athletes participating in a boxing tournament following each match. In one instance, vowel sounds are isolated from the recordings and acoustic features are extracted and used to train several one-class machine learning algorithms in order to predict whether an athlete is concussed. | 05-19-2016 |
