The present disclosure provides a system and method for image data acquisition. The method may include acquiring physiological data of a subject. The physiological data may correspond to a motion of the subject over time. The method may include obtaining a trained machine learning model configured to detect feature data represented in the physiological data. The method may include determining, based on the physiological data, an output result of the trained machine learning model that is generated based on the feature data. The method may include acquiring, based on the output result, image data of the subject using an imaging device.

A posture determination apparatus including at least two vibration sensors and a controller. The controller causes the vibration sensors to detect vibrations while the user is lying in bed, calculates waveforms from the detected vibrations and recognizes the characteristics of the waveforms, and determines the posture of the user based on the characteristics. Thereby, it is possible to provide a posture determination apparatus and capable of appropriately determining the posture of the user which is one factor of the state of the user.

A system includes a processor and an output device. The processor is configured to: (a) receive electrical signals indicative of measured positions of (i) one or more chest position sensors attached externally to a chest of a patient, and (ii) one or more back position sensors attached externally to a back of the patient; (b) compare between (i) a first shift between the measured positions and respective predefined positions of the one or more chest position sensors, and (ii) a second shift between the measured positions and respective predefined positions of the one or more back position sensors; and (c) produce an alert in response to detecting a discrepancy between the first and second shifts. The output device is configured to output the alert to a user.

Examples of systems and methods are described for detecting heart beats of a subject. The systems and methods may be based on motion of the subject due to cardiac activity, and may operate without contact with the subject. Example systems may provide an interrogation signal to the subject. Reflected signals from the subject are incident on a microphone array. The reflected signals may be processed and beamformed using a set of beamforming weights. The beamforming weights may be selected in a manner to reduce components of the reflected signals due to breathing motion of the subject while increasing the relative contribution of the reflected signals due to cardiac activity. The beamformed signal may provide a waveform indicative of heart beats. Inter-beat intervals, heart rates, and/or other health metrics may be calculated based on the waveform.

Systems and methods for monitoring vital signs (e.g. heartbeat, respiration) using FMCW millimeter wave radar are disclosed herein. A transceiver is used to transmit a first signal (FMCW) and receive a second signal (reflected). The transceiver transmits the second signal data to a computing device. A first set of radar data is generated by software on the computing device, based on the received second signal. A first set of Doppler interval measurements is obtained from the first set of radar data. A high Doppler response is obtained from the first set of Doppler interval measurements and vital sign data is extracted from the high Doppler response. Advantages include the use of Doppler frequencies which are free to use according to FAA specifications; living organisms (subjects) are not affected by the radiation or the transmission path; and a subject may be remotely monitored without requiring physical access.

A system for treating disordered breathing of a human being includes an implantable transvenous stimulation lead having at least one stimulation electrode and a sensor configured to detect activity level of the human being. The system includes an energy source, a pulse generator and circuitry, the circuitry operative to receive a signal indicative of the activity level of the human being from the sensor, wherein the circuitry is configured to cause the energy source and the pulse generator to deliver spaced apart stimulation signals to the at least one stimulation electrode while the activity level of the human being is sufficiently low to be indicative of sleep. Spaced apart stimulation pulses from the electrode are configured to extend a duration of a time of at least one breath being defined as the time from an onset of inhalation to the onset of inhalation of a successive breath.

An information processing device (10) is an information processing device attached to a patient, and includes an acceleration sensor (13) (corresponding to an example of a “sensor”) that detects movement of the patient which movement is associated with respiratory movement, an acquisition unit (163a) that acquires sensor data of the acceleration sensor (13), an estimation unit (163b) that estimates a respiratory condition of the patient from the sensor data, and a determination unit (163c) that determines whether to transmit information related to the respiratory condition to an external device on the basis of the estimated respiratory condition.

A contactless health monitoring device may perform a beam steering process that creates a plurality of beam-steered radar data streams from the received radar data stream. The contactless health monitoring device may determine breathing displacement for a user in relation to time for each spatial zone radar data stream. The contactless health monitoring device may analyze the breathing displacement for the user in relation to time for each spatial zone radar data stream. The contactless health monitoring device may output a screening result based on analyzing the breathing displacement for the user.

A device and method for monitoring respiration of a patient is disclosed. The device includes a sensor unit provided with two V-shaped flex sensors and a measuring unit coupled to the sensor unit. The flex sensors can be resistive or capacitive. In use the measuring unit is attached to the chest of the patient and the sensor unit is attached to the abdominal wall of the patient. Relative displacement of the patient's chest and the abdominal wall are detected during respiration and patient's respiration rate is determined from the detected relative displacements of the chest and the abdominal wall.
