The method and system for monitoring cough comprises receiving audio signals or audio recordings, where said signals or audio recordings comprises one or more of silent segments, cough sound segments, speech segments and extraneous noise. The processing of said received sound signals or sound recordings comprise one or more of removing one or more speech components from speech segments to render the speech unintelligible and clipping said silent segments, wherein one or more speech components include vowel sounds. Further processing of said received audio signals or audio recordings further comprises compressing said audio signals or audio recordings. In the alternative, processing of audio signals or audio recordings comprises compressing a resultant signal after said removal of one or more speech components and/or clipping of silent segments from said audio signals.

Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

A sleep monitor for monitoring baby sleep uses sleep state classification based on heartbeat feature respiration features. The sleep monitor automatically retrains the classification during use of the sleep monitor. Training examples for use in this training process are generated automatically by detecting time instants whereat the baby in the bed is in a wake state, based on signals from the at least one of a sound feature detector a movement feature detector (112) and an open eye detector (114). The retraining may comprise using time sequence from the end of detection of wake states to assign a class to heartbeat feature and/or respiration feature values during that time sequence for the training process. In an embodiment, the retraining comprises clustering detected heartbeat feature and/or respiration feature values detected outside the detected wake states.

Disclosed is an apparatus for recording respiratory rate of a subject. The apparatus comprises a first component to be arranged on the subject and away from nostrils of the subject, the first component comprises a battery, optionally electronics for the sensor, and electronics for transmitting respiration rate data; and a second component for being arranged in an area of the nose of the subject, the second component comprising at least one sensor for recording respiratory rate. Disclosed is also a method for recording respiratory rate of a subject with such an apparatus. The method comprises arranging the second component in an area of the nose of the subject; arranging the first component on the subject and no further than 30 centimeters from the second component; recording respiratory rate data with the second component, and sending the respiratory rate data to the first component; and sending the respiratory rate data from the first component to a monitor or a hub.

Methods and apparatus provide physiological movement detection, such as gesture, breathing, cardiac and/or gross motion, such as with sound, radio frequency and/or infrared generation, by electronic devices such as vehicular processing devices. The electronic device in a vehicle may, for example, be any of an audio entertainment system, a vehicle navigation system, and a semi-autonomous or autonomous vehicle operations control system. One or more processors of the device, may detect physiological movement by controlling producing sensing signal(s) in a cabin of a vehicle housing the electronic device. The processor(s) control sensing, with a sensor, reflected signal(s) from the cabin. The processor(s) derive a physiological movement signal with the sensing signal and reflected signal and generate an output based on an evaluation of the derived physiological movement signal. The output may control operations or provide an input to any of the entertainment system, navigation system, and vehicle operations control system.

A method is provided for monitoring a current respiratory curve of a patient with regard to a recording region which is imaged by magnetic resonance scanning. The method includes acquiring a reference respiratory curve of the patient over a plurality of respiratory cycles; establishing a respiration state of the patient that is suitable for the magnetic resonance scanning based on the reference respiratory curve; determining at least one reference recording time window and a trigger threshold value for starting a magnetic resonance scan based on the previously determined respiration state; carrying out at least one magnetic resonance scan within the determined reference recording time window of the current respiratory curve using the trigger threshold value; and continually acquiring and monitoring the current respiratory curve during the magnetic resonance scan in the reference recording time window.
