A body motion determination system for determining whether a body motion of a subject (S) on a bed (BD) presents or not, includes a load detector (11, 12, 13, 14) configured to detect a load of the subject on the bed; a non-negative-valued average calculating unit (313) configured to calculate a non-negative-valued average of a detection value of the load detector; and a threshold value setting unit (315) configured to set a threshold value to be used in determining whether the body motion of the subject presents or not, based on the non-negative-valued average calculated in a resting period in which the subject merely performs a respiration.

Disclosed is a biosensor arrangement structure, including: a plurality of biosensors that is disposed in a seat for supporting an occupant and that measures a health condition of the occupant. The seat includes: a seat body for holding the occupant; and an auxiliary supporter for supporting a body part of the occupant except for a torso and thighs. At least one of the plurality of biosensors is disposed at the auxiliary supporter.

Attributes of a human or animal body are detected by the generation and detection of an electric field. A laminated membrane, connected to a control circuit, is placed over an electrically conductive ground-plane. An upper-mattress is placed above this for supporting a human or animal body. To improve the response of the detector, a response-enhancement-layer of a substantially electrically non-conducting compressible-material containing electrically-conductive-particles, such as carbon particles, is located between the laminated-membrane and the upper-mattress.

Methods and devices provide physiological movement detection, such as gesture, breathing, cardiac and/or gross body motion, with active sound generation such as for an interactive audio device. The processor may evaluate, via a microphone coupled to the interactive audio device, a sensed audible verbal communication. The processor may control producing, via a speaker coupled to the processor, a sound signal in a user's vicinity. The processor may control sensing, via a microphone coupled to the processor, a reflected sound signal. This reflected sound signal is a reflection of the generated sound signal from the vicinity or user. The processor may process the reflected sound, such as by a demodulation technique, to derive a physiological movement signal. The processor may generate, in response to the sensed audible verbal communication, an output based on an evaluation of the derived physiological movement signal.

In some embodiments, a tracheotomy tube monitoring device of a monitoring system includes a tube mounting portion configured to mount to a tracheotomy tube, sensing means for monitoring respiration of a patient in which the tracheotomy tube is inserted, and alert means for alerting relevant persons when data collected by the sensing means indicate that there is a problem.

Methods and apparatuses for identifying food chewed or beverage drank are disclosed herein. In embodiments, a device may comprise one or more sensors to provide vibration signal data representative of vibrations sensed from a nasal bridge of a user wearing the device, a chewing analyzer to extract from the vibration signal data a first plurality of features associated with chewing activities, and/or a drinking analyzer is to extract from the vibration signal data a second plurality of features associated with drinking activities. The extracted first and/or second plurality of features, in turn, may be used to determine a category of food the user was chewing, or a category of beverage the user was drinking. In embodiments, the methods and apparatuses may use personalized models.

Cough is a common experience and the most frequent reason why an individual seeks a visit to a physician. The prevalence of cough is about 10+% of the population. Cough is a manifestation of many aerodigestive tract disorders and especially consequential for serious lower airway diseases such as respiratory infections, chronic obstructive pulmonary disease (COPD) and asthma because increased coughing leads to emergency room visits and hospitalization. There is a need for methods to oversee coughing frequency in certain patients. Traditionally, all automated cough monitors have used cough sound as the signal for the measurement of cough. In the present invention movements of the diaphragm muscle, recorded by a motion sensor placed above the xiphoid process, are used for counting coughs. A device for such recordings is described and data were collected. This method is validated by using citric acid spray to trigger cough sounds and to show that the provoked acoustic signal is matched by the electronic signals from the movement sensors. The xiphoid process is a unique anatomical landmark for the non-acoustic detection of cough.

A physiological monitoring method and device, the device comprising: a fixation band adapted to be fastened around a user's torso; a monitoring assembly fastened to the fixation band, the monitoring assembly comprising: at least one deformable member adapted to be deformed in response to an expansion of the user's torso; at least one deformation sensor operatively connected to the at least one deformable member for measuring a deformation of the deformable member; a processing unit operatively connected to the at least one sensor for determining a physiological parameter value of the user based on the measured deformation.
