In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.

A system for monitoring a health parameter in a person is disclosed. The system includes a frequency synthesizer configured to generate radio waves across a range of stepped frequencies, at least one transmit antenna configured to transmit the radio waves below the skin surface of a person, a two-dimensional array of receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves, processing circuits configured to generate data that includes amplitude and phase data in response to the received radio waves, and means for determining a value that corresponds to a health parameter of the person in response to the amplitude and phase data.

A wearable device for reducing exposure to pathogens of possible contagion includes a detection component configured to detect a proximate subject in relation to a user wherein the user is in possession of the wearable device, a data input component configured to capture data relating to the proximate subject, wherein the data relating to the currently proximate subject further comprises an inoculation status of the currently proximate subject, a processor configured to calculate a degree of transmission threat between the user and the proximate subject, wherein calculating the degree of transmission threat further comprises identifying a pathogen of possible contagion, locating a reproduction rate for the pathogen of possible contagion, calculating the degree of transmission threat as a function of the data input component and the reproduction rate, and a user-signaling component configured to generate an output as a function of the degree of transmission threat.

Embodiments of this disclosure provide a living object detection method and apparatus and electronic device. The apparatus includes a processor to calculate a distance matrix according to variance of Fourier transform amplitude values of radio signals received by a radio signal receiver within a determined period of time; and to calculate a distance between an object among objects and the radio signal receiver according to the distance matrix. According to this disclosure, a position of a living object among the objects may be detected based upon the distance in multiple scenarios.

Sensors that detect an analyte via spectroscopic techniques using non-optical frequencies such as in the radio or microwave frequency range of the electromagnetic spectrum or optical frequencies in the visible range of the electromagnetic spectrum. An analyte sensor described herein includes a detector array having at least one transmit element and at least one receive element. The transmit element and the receive element can be antennas or light emitting elements such as light emitting diodes. The sensor is controlled to implement first and second frequency sweeps and the frequency sweeps have at least one overlapping range of frequencies where the operation times are the same between the first and second frequency sweeps.

Methods, devices, and systems for contactless cough detection and attribution are presented herein. Audio data may be received using a microphone. A cough may be identified as having occurred based on the received audio data. Radar data may be received indicative of reflected radio waves from a radar sensor. A state analysis process may be performed using the received radar data. The detected cough may be attributed to a particular user based at least in part on the state analysis process performed using the radar data.
