Abstract: The invention describes a method for extracting several physiological parameters such as cardiac cycle parameters with one single measurement over a time period and for monitoring mechanical and electrical cardiac activity. The invention finds its use in providing continuous monitoring of heart mechanical and electrical activities over time. Such signal may be transmitted to clinics of family doctors to keep track of the subject's health.

Abstract: The plant water Anomalous Phase sensor can determine moisture levels in plant leaves, stems and wood. The sensors described include several embodiments of the sensor, all of which estimate moisture levels by determining changes in the phase spectrum of an anomalous-phase resonator. Two embodiments include a planar transmitting antenna array with two slightly detuned patch antennas and a detector. In a first embodiment, the detector is a dipole antenna centered and out of plane with the transmitting antenna array. In a second embodiment, the detector is a singular rectangular patch antenna coplanar with the transmitting antenna array. The third embodiment is similar to the second embodiment, but is formed on a flexible substrate, so that the sensor can be wrapped about a twig, branch or other plant structure, in a non-coplanar arrangement. To compensate for temperature affects, a reference sensor may be integrated with an active sensor.

Abstract: The fuel quality sensor includes two rectangular parallepiped waveguides of equal dimensions stacked one atop the other and having a common ground. A thin wire extends through the intermediate wall(s) between the upper and lower waveguide cavities. An input connector is mounted on a sidewall of the upper waveguide, and an output connector is mounted on a sidewall of the lower waveguide cavity. A fluid conduit extends through the upper waveguide cavity adjacent the wire. A tunable microwave signal or wideband time domain pulse is applied to the input connector while fuel is flowing through the conduit. If the fuel flowing in the conduit is uncontaminated, the output signal at the second connector will show no change from the tunneling frequency, but if the fuel is contaminated, the change in the fuel's dielectric constant will result in a change in tunneling frequency and/or tan ? at the second connector.

Abstract: The microstrip Fano resonator switch is a microstrip circuit having a varactor diode electrically connected between identical quarter-wavelength open stubs formed from two elongate planar strip elements disposed on a substrate having a permittivity of approximately 2.94 and a thickness of approximately 0.76 mm, the circuit forming a Fano resonator switch that provides approximately 50 dB of isolation.

Abstract: The microstrip circuits exhibiting electromagnetically induced transparency and Fano resonance include a microstrip transmission line and at least two identical parallel quarter-wavelength open stubs extending from the transmission line in close proximity so that mutual coupling between the electromagnetic fields at adjacent ends of the stubs induces Faro resonances and electromagnetically induced transparency (EIT). The circuits may be used for microwave buffers, or when a variable capacitance, such as a varactor, is inserted between the open ends of the stubs, the circuits may be used for active transmission phase control.
