A method for range of motion (ROM) tracking, that determines with a ROM tracking system, an exercise identified by a caregiver to be performed by a subject by positioning a sensor of the ROM tracking system to allow the sensor to detect at least one movement by the subject during a performance of the exercise, and then detecting, through the sensor, at least one movement of the subject. The system further analyzes the movement by the subject to determine a range of motion of the at least one movement; recording through a user interface an indication by the subject of an experiential narrative; and finally, providing a report to the caregiver, where the report contains the results of at least one movement in conjunction with at least a portion of the experiential narrative.

A fever-causing disease outbreak detection system for an early warning of the outbreak of an infectious disease. The system uses an array of infrared detectors to measure the temperatures of individuals in a population. The measured temperatures are used to create a measured population temperature distribution. A central control unit generates a predicted population temperature distribution using environmental data such as local atmospheric conditions and compares the predicted population temperature distribution to the measured population temperature distribution. If an outbreak is detected, an alert is issued.

A method of cough detection in a headset, the method comprising: receiving a first signal from an external transducer of the headset; receiving a second signal from an in-ear transducer of the headset; and detecting a cough of a user of the headset based on the first and second signals.

The present disclosure provides methods, devices, and systems for determining a state or condition of a subject. A method for determining a state or condition of a heart of a subject may include using a monitoring device comprising an electrocardiogram (ECG) sensor and an audio sensor to measure ECG data and audio data from an organ of the subject, and transmitting the ECG data and the audio data wirelessly to a computing device. A trained algorithm may be used to process the ECG data and the audio data to determine the state or condition of the organ of the subject. More specifically, the trained algorithm can be customized for a specific indication or condition. An output indicative of the state or condition of the heart of the subject may be provided on the computing device.
