A respiration rate measurement apparatus including a plurality of sensors for concurrently generating temperature, pressure and acoustic data representing one or more successive breaths and a method of generating fusion data from the plurality of data streams as a weighted average based on determined correlation coefficients and calculation of a respiratory rate.

The present invention relates to systems and methods for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising: a mechanical coupler comprising means for restricting the jaw position of the patient; means for recording an utterance; and processing means for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value. In addition the present invention relates to the use of the above mentioned systems as a diagnostics tool for assessing obstructive sleep apnea.

A multifunctional pillow with an adjustable height includes a pillow body and a pillowcase. The fabric shell is stretchable along a length and a height of the fabric shell, but is not stretchable along a width of the fabric shell. The pillowcase is provided with a main space and a plurality of compression spaces, and the different spaces are separated from and communicate with each other by a zipper mechanism, and a mounting pocket is provided at the bottom of the pillowcase. The height of the pillow can be quickly adjusted through the compression spaces. When users sleep on their backs or on their sides, the cervical spine can be supported by adjusting the height of the pillow. The mounting pocket of the pillow is equipped with inflatable cushions and sensors.

Provided are apparatuses and methods for non-invasively and continuously measuring physiological parameters of a mammal subject. The apparatus includes multiple sensor systems attached to the mammal subject, and a microcontroller unit (MCU). The sensor systems are time-synchronized and communicate with each other wirelessly and bidirectionally. Each of the sensor systems includes at least one sensor configured to detect a vital sign of the mammal subject and generate a corresponding one of the physiological parameters. The MCU is in wireless communication with the plurality of sensor systems. In operation, the MCU receives, from the sensor systems, and displays the physiological parameters of the mammal subject. The apparatus and method can be used in applications such as developing therapeutics or vaccines for a disease, or diagnosing a disease.

A system monitors fatigue of a user. The system (100) may include one or more data sources, such as a non-obtrusive sleep sensor, configured to generate objective sleep measures of the user. The system may also include a fatigue monitoring module, which may be configured to generate an assessment, such as in one or more processors, of the fatigue state of the user based on the data from the one or more data sources.

An integrated cardio-respiratory system that fuses continuously recorded data from multiple physiological sensor sources to acquire signals representative of acoustic events caused by physiological phenomena occurring in the cardiac and/or arterial structures underneath particular areas of the chest and/or neck to monitor cardiac and respiratory conditions.

Systems and methods are provided that provide respiration entrainment cues to a user to encourage relaxation or a sleep state. The entrainment cues may be audible, visible, or tactile (or any combination). The entrainment cues include a rhythmic component associated with a target respiration rate and may include sub-components associated with a target breath architecture, such as an inhale-exhale cycle. The systems and methods detect the user's respiration to determine whether the user's respiration matches the entrainment cues or whether the user has fallen asleep.

There are provided a biological signal measurement device capable of obtaining a variety of biological information and applicable also to medical fields and the like, a biological state inference device, and a biological state inference system using these. The biological signal measurement device 1 of the present invention includes three biological signal detection units, namely, a left upper part biological signal detection unit 11, a right upper part biological signal detection unit 12, and a lower part biological signal detection unit 13. The biological state inference device 1 is capable of obtaining a highly precise inference-use processed waveform from which electrical noise has been removed, by using an appropriate combination of time-series data obtained from the three biological signal detection units 11 to 13. Because the precision of an inference-use processed waveform corresponding to target biological information on breathing, heart sound, or the like increases, the precision of inferring a biological state also increases.

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 method and apparatus for the treatment of Sleep Apnea events and Hypopnea episodes wherein one embodiment comprises a wearable, belt like apparatus containing a microphone and a plethysmograph. The microphone and plethysmograph generate signals that are representative of physiological aspects of respiration, and the signals are transferred to an imbedded computer. The embedded computer extracts the sound of breathing and the sound of the heart beat by Digital Signal Processing techniques. The embedded computer has elements for determining when respiration parameters falls out of defined boundaries for said respiration parameters. This exemplary method provides real-time detection of the onset of a Sleep Apnea event or Hypopnea episode and supplies stimulation signals upon the determination of a Sleep Apnea event or Hypopnea episode to initiate an inhalation. In one embodiment, the stimulus is applied to the patient by a cutaneous rumble effects actuator and/or audio effects broadcasting.
