A system for monitoring dietary activity of a user includes a wearable device having at least one audio input unit configured to record an audio sample corresponding to audio from a user's neck. The system further includes a processor configured to execute programmed instructions stored in a memory to obtain an audio sample from the audio input unit of a wearable device, determine segmental feature values of a set of selected features from the audio sample by extracting short-term features in the set of selected features from the audio sample and determining the segmental feature values of the set of selected features from the extracted short-term features. The processor is further configured to, using a classifier, classify a dietary activity based on the determined segmental feature values of the audio sample and generate an output corresponding to the classified dietary activity.

Example methods, apparatus, and articles of manufacture for monitoring use of a research device is disclosed. The disclosed example includes producing monitored data by monitoring at least one of the user's heart activity, the user's breathing activity, the user's borborygmus (gastrointestinal noise), the user's vascular pattern, the user's facial and/or ear patterns, the user's fingerprint and/or handprint, and the user's retinal and/or iris pattern, and determining the user's compliance with a predetermined criterion for use of the portable research device based on the monitored data.

A wireless stethoscope is described, having wireless sensors that are enclosed in disposable pads so that the same pads are not used on more than one patient, preventing cross-infection of patients associated with conventional stethoscopes. The present wireless stethoscope also detects pulmonary sounds and cardiac sounds, allowing the user to monitor one or the other without interference. Also described is a method for diagnosing a pulmonary condition using the wireless stethoscope.

A garment comprising a central portion including a plurality of electrocardiogram leads, a plurality of auscultation acoustic sensor devices, a flexible respiratory sensor located so that it substantially circumscribes the garment, one or more blood pressure cuff portions located on an at least one arm portion of the garment, wherein the cuff portions are adapted to be loosened and/or tightened and a hardware device for sending and receiving signals via wired or wireless communication.

Systems are provided which analyze the large intestine contents and utilize acoustic signals detected during delivery of water into the large intestine and drained large intestine contents to derive large intestine characteristics such as microbiotal analysis from at least two portions of the large intestine. Systems may include a water delivery unit including a water supply and a nozzle connected thereto, configured to introduce water controllably into a patient's large intestine, and an analysis unit that provides information about the drained contents using optical examination or biological assays. The information may be related to acoustic analysis of signals from acoustic sensors that are attachable to a patient's abdomen. A variety of sensor configurations, positioning options, analysis strategies and large intestine characteristics are presented.

A method for evaluating a gastrointestinal tract may include receiving an electrical signal that includes data pertaining to motility in the gastrointestinal tract of a patient and analyzing one or more characteristics of the electrical signal relative to one or more respective thresholds indicative of an occurrence or an imminence of a condition of the gastrointestinal tract.

According to certain described aspects, multiple acoustic sensing elements are employed in a variety of beneficial ways to provide improved physiological monitoring, among other advantages. In various embodiments, sensing elements can be advantageously employed in a single sensor package, in multiple sensor packages, and at a variety of other strategic locations in the monitoring environment. According to other aspects, to compensate for skin elasticity and attachment variability, an acoustic sensor support is provided that includes one or more pressure equalization pathways. The pathways can provide an air-flow channel from the cavity defined by the sensing elements and frame to the ambient air pressure.

The present disclosure discloses a smartphone based telemedical devices incorporating into smartphone medical devices such as stethoscopes, thermometers, ultrasound imaging devices and/or alarm generators for diagnosis or determination of the disease or health status or condition of a user. The present smartphone based telemedical devices can be advantageously and conveniently used to measure and generate and/or remotely transmitting the medical data or information generated by the incorporated medical devices thus allowing an accurate and rapid determination of the status of a user particularly under emergency particularly when there are no regular medical or hospital services are available.

A swallowing diagnosis apparatus includes a controller which enables a first swallowing determination process of determining whether or not there is an aspiration risk in the swallowing on the basis of respiratory phases before and after a period in which swallowing has been estimated as having occurred; and a second swallowing determination process of extracting reference information including at least one of the sound information and the respiration information in a predetermined period including the period in which swallowing has been estimated as having occurred, obtaining a feature quantity from the extracted reference information, and performing a machine learning process on the obtained feature quantity to determine whether or not there is a possibility of dysphagia in the swallowing; and a display control process of causing a determination result obtained by the first swallowing determination process and a determination result obtained by the second swallowing determination process to be displayed.

An acoustic monitoring system has an acoustic front-end, a first signal path from the acoustic front-end directly to an audio transducer and a second signal path from the acoustic front-end to an acoustic data processor via an analog-to-digital converter. The acoustic front-end receives an acoustic sensor signal responsive to body sounds in a person. The audio transducer provides continuous audio of the body sounds. The acoustic data processor provides audio of the body sounds upon user demand.
