When performing electrocardiographic signal measurement, through mounting the ear-worn structure on an ear of the user, the first electrode contacts the skin of the ear or around the ear, and through mounting the cuff surrounding the upper limb, the second electrode contacts the skin of the upper limb, enabling the processor to acquire electrocardiographic signals through the first electrode and the second electrode.

An apparatus designed to induce brainwave synchronization in order to reduce or eliminate anxiety attacks, prevent stress and achieve desired brainwave states is disclosed. In operation, the device uses amplitude and frequency characteristics of stored .wav files containing isochronic or other tones to generate signals that are transmitted to the user through a variety of emission techniques including vibration, electrical, photic, and audial. The signals imparted to the user's cranium tend to be mimicked or followed such that the user's brainwave state is altered by the transmission of the desired signals. In various embodiments, the device and system may also possess bio-feedback and electroencephalogram capabilities. The device records metrics and usage data through a communications link with the user's smartphone, tablet or other device.

A physiological acoustic monitoring system receives physiological data from an acoustic sensor, down-samples the data to generate raw audio of breathing sounds and compresses the raw audio. The acoustic monitoring system has an acoustic sensor signal responsive to tracheal sounds in a person. An A/D converter is responsive to the sensor signal so as to generate breathing sound data. A decimation filter and mixer down-samples the breathing sound data to raw audio data. A coder/compressor generates compressed audio data from the raw audio data. A decoder/decompressor decodes and decompresses the compressed audio data into decompressed audio data. The decompressed audio data is utilized to generate respiration-related parameters in real-time. The compressed audio data is stored and retrieved so as to generate respiration-related parameters in non-real-time. The real-time and non-real-time parameters are compared to verify matching results across multiple monitors.

A first sound is output by a first transducer in an earcup located at a pinna. Respective second sound based on the output of the first audio sound is detecting by each of one or more microphones in the earcup located at the pinna. Based on the respective detected second sound, a non-linear transfer function is determined which characterizes how sound is transformed via the pinna. A signal indicative of one or more audio cues for spatializing third sound is generated based on the determined non-linear transfer function.

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.

A tracking system for tracking a medical attachment device within a tracking area, the tracking system including a first reflector defining a first tracking region, a medical attachment device having at least one reflector sensor operable to integrate the first reflector, and a processor communicatively coupled to the medical attachment device, the processor operable to determine a distance between the medical attachment device and the first reflector to determine a location of the medical attachment device relative to a subject.

A system measures performance activity of a user using a motion capture device, such as one or more knee sleeves each a plurality of inertial-measurement unit. Captured motion characteristic data is classified against previously captured data and then mapped to particular audio effects, which are then altered in different ways depending on the classification and provided the user. The audio feedback works to improve the user's performance of the activity by changing between negative and positive feedback depending on the user's performance. The system regularly measures the motion capture data, altering audio effects provided to the user, until the user reaches an improvement goal.

A device includes an EMG processing application operable with a processing module to receive an output signal from EMG testing, wherein the output signal represents electrical activity of at least one muscle. The EMG processing application is operable to process the output signal to detect at least one type of waveform of a plurality of types of waveforms from the output signal and display the detected at least one type of waveform.
