Circuits, systems and methods that utilize two transducers, of which at least one is a piezoelectric transducer, adapted and coupled to receive and/or generate signals that include a power transmission component and an informational content in the forms of sound waves, mechanical vibrations, and/or electromagnetic energy. In one version, two transducers each receive and/or generate separate vibrational energy signals that bear information and transmit electrical power. Two or more transducers coupled to a switching circuit may send or receive piezo-electrical circuit output signals that include a carrier wave having different frequencies that are within separate frequency ranges. Two or more transducers may generate output signals that are simultaneously processed by or multiplexed by a switching circuit.

Method and apparatus for a wireless charging and communication system

A target receives two signals of different modes in association with a first location and another two signals in association with a second location. The first two signals are assumed to have been emitted effectively simultaneously from the first location, and the second two signals are assumed to have been emitted effectively simultaneously from the second location. A first distance is calculated in view of a receipt time difference of the first two signals in view of differing rates of propagation assumed between these two signals; a second distance is calculated in view of another receipt time difference of these second two signals in view of differing rates of propagation assumed between each of these other signals. A possible location of the target is then calculated in view of the first distance and its associated first location and the second distance and its associated second location.
