A single non-thermal atmospheric plasma generation device is used to detect and analyze vital fields of a living subject to determine the presence of a condition, such as an illness or injury, and responsively modify characteristics of the plasma to treat, heal, or alleviate the condition. The device includes a capacitance dielectric discharge array of plasma emitters, and a controller having a power supply, a transformer, and circuit components for driving the transformer at a resonant frequency of the plasma emitters to cause the plurality of plasma emitters to ionize surrounding air and produce the non-thermal plasma. The resonant frequency is around 60 GHz and harmonics thereof. A receiver of the device recovers frequency mixing products from the plasma, which are extracted by signal processing circuitry; signals in the VHF and UHF bands are extracted and analyzed to determine whether signatures of particular vital fields are present.

A pulse measurement device is provided, including a first signal source, a second signal source, two microwave resonators, two mixers, and a signal processing unit. The first signal source and the second signal source output a first high-frequency signal and a second high-frequency signal, respectively. Each of the microwave resonators generates an electric field according to the first high-frequency signal, and senses a variation in the electric field which is interfered by a pulse to obtain a sensing signal. Each of the mixers is coupled to one of the microwave resonators, to mix the sensing signal and the second high-frequency signal to output a down-converted signal. The signal processing unit respectively demodulates amplitudes of the down-converted signals of the two mixers to obtain amplitude signals.

An ambient monitoring device includes a housing, contactless sensors coupled to the housing, and a processing device disposed in the housing. The processing device is coupled to the contactless sensors. The processing device is to receive, from one or more contactless sensors of the plurality of contactless sensors, historical sensor data. The processing device is further to determine baseline vital signs based on the historical sensor data. The processing device is further to receive, from the one or more contactless sensors, current sensor data associated with a user that is within a threshold distance of the ambient monitoring device without contacting the ambient monitoring device. The processing device is further to determine, based on the current sensor data, current vital signs of the user. Responsive to determining the current vital signs do not meet the baseline vital signs, the processing device is to provide an alert.

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 near-field sensor method and device for obtaining cardiovascular information is disclosed. A transmission-line aperture arrangement configured to guide electromagnetic waves and emit near-field fringing energy, is placed near the skin. The transmission line is excited at a narrow-band Gigahertz frequency. The near-field fringing energy emitted by the sensor device penetrates at least partially into the skin and underlying blood vessels, and this energy is partially absorbed and partially phase shifted in a time varying manner according to the changes in physiology of the skin. The status of the sensor device is monitored over a plurality of time intervals, and changes in both the phase and the amplitude of the signals passing though the transmission line are used to determine the cardiovascular information such as heart rates. Various transmission-line configurations, and various reference transmission-line methods to reduce low-frequency noise, are also discussed.

Biomedical images of both anatomical structure and real-time changes in neuronal, metabolic, positional, and vascular function in humans and animals is described. Ultra-wideband (UWB) pulse or square wave generators and electrical samplers, implemented using integrated circuits are used to make arrays of miniaturized microwave modules that are placed around the portion of interest in the body or head, allowing images to be made through either time-domain transmission of these pulsed waves through the body, or time domain reflectivity of the waves from internal structures, or their combination. Signal processing separate and extract the time-varying functional information from the static structural image data. The time-varying functional information from certain brain regions can be interpreted in order to control prosthetics, Brain-Machine-Interfaces and the like.
