A sensor pill in accordance with an embodiment, suitable for being swallowed by a patient is provided. The sensor pill has a casing. Additionally, the sensor pill has one or more sensors. The one or more sensors have a microphone and/or an acceleration sensor.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

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 method to measure sound-producing behaviors of a subject with a power- and bandwidth-limited electronic device that includes a processor includes measuring, by a microphone communicatively coupled to the processor, sound in a vicinity of the subject to generate an audio data signal that represents the sound. The method also includes measuring, by at least one second sensor communicatively coupled to the processor, at least one parameter other than sound to generate at least a second data signal that represents the at least one parameter other than sound. The method also includes detecting one or more sound-producing behaviors of the subject based on: both the audio data signal and the second data signal; or information derived from both the audio data signal and the second data signal.

A health management system and a health management method are provided. The health management method includes: measuring a position information of a person; determining to measure a physiological state information of the person according to the position information; and generating a physiological state report according to the physiological state information.

A method for quantifying swallowing function can include subjecting swallowing segments and non-swallowing segments of vibrational data to processing selected from the group consisting of adaptive trimming, false positive reduction, and a combination thereof. Preferably the vibrational data represents swallowing activity, is from a sensor positioned on the throat of a patient, and is associated with at least one axis selected from the group consisting of an anterior-posterior axis and a superior-inferior axis. Preferably a processing module operatively connected to the sensor performs the processing of the swallowing segments and the non-swallowing segments of the vibrational data. A device comprising a processing module and a sensor such as a single-axis accelerometer or a dual axis accelerometer can perform one or more steps of the method.

A multi-modal approach is used to detect and track inflammation, and identify location of inflammation, which is revealed in changes in tissue and physiological properties that underlie sub-systems, including respiratory, sinus, laryngeal, articulatory, facial and gastrointestinal components.

A wearable device for detecting eating episodes uses a contact microphone to provide audio signals through an analog front end to an analog-to-digital converter to digitize the audio and provide digitized audio to a processor; and a processor configured with firmware in a memory to extract features from the digitized audio. A classifier determines eating episodes from the extracted features. In embodiments, messages describing the detected eating episodes are transmitted to a cell phone, insulin pump, or camera configured to record video of the wearer's mouth.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.
