Abstract: An electrical source excites a conductive object. A receiver is electrically connected to the object to receive energy from the object, and can power a device. The object can be non-resonant under excitation by the source, and the receiver is excited into resonance by electrical contact with the object. The object can also be resonant under the excitation by the source, and the receiver receives energy from the resonance of the object.

Abstract: A dissipation-based sensor includes a single resonator with a nano-structured surface. The sensor exhibits improved sensitivity, up to about 2 orders of magnitude higher than a single resonator without a nano-structured surface. The sensor operates by measuring and estimating the fluid friction per oscillation cycle, operating in normal conditions without vacuum (e.g., in air or other ambient gas) at room temperature. The sensor can provide measurement data at a speed that is orders of magnitude faster than pre-existing resonance-based methods, as it is based on measurements from a few cycles only. The dissipation-based sensor may be utilized in a broad range of fast, inexpensive, hand-held measuring devices. Additionally, the sensor is capable of operating at standard temperature and pressure.

Abstract: Dielectric in situ heating of materials using a resonant, non-radiating transformer. The target material is strategically formed into a part of the capacitance of the resonant system. The system may be used to heat in situ materials such as oilsands.
