Abstract: A method for evaluating for the presence of the COVID disease by detecting one or more biomarkers using a breathalyzer. The breath sample taken from the subject is passed over a sensor which changes resistance in the presence of nitric oxide as a function of concentration. The resistance pattern of the subject having the COVID disease will have a distinct shape, approximating the appearance of the small Greek letter omega (?). Test results can be generated in less than a minute.

Abstract: A method for evaluating for the presence of the COVID disease by detecting one or more biomarkers using a breathalyzer (138). The breath sample (2) taken from the subject (10) is passed over a sensor (140) which changes resistance in the presence of nitric oxide as a function of concentration. The resistance pattern of the subject (10) having the COVID disease will have a distinct shape, approximating the appearance of the small Greek letter omega (?). Test results can be generated in less than a minute.

The RFID tag identifies the pharmaceutical agent and the RFID reader wirelessly communicates with a central monitoring system upon ingestion of the pharmaceutical agent.

Abstract: A method of separating and localizing sources of traveling waves, by obtaining linearly independent time-differentiated instantaneous observations of the sources, from spatial derivatives of the traveling wave acquired using a distributed sensor or a sensor array. The sources are blindly separated by direct application of (static) independent component analysis on the time-differentiated observations, yielding both the sources and their direction cosines relative to the sensor geometry. The method is suited for arrays of small aperture, with dimensions shorter than the coherence length of the waves. In one preferred embodiment, three sources are separated and localized from differential observations on four coplanar sensors positioned on the corners of a square.
