    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting characteristics of an input signal. One aspect includes a first finite input response (FIR) filter, a second FIR filter, and a controller coupled with the first and second FIR filters. The first FIR filter receives an input signal and a first reference signal. The first FIR filter filters the first reference signal to generate a first sinusoidal signal and mixes the first sinusoidal signal and the input signal to generate a first mixed signal. The second FIR filter receives the input signal and a second reference signal. The second FIR filter filters the second reference signal to generate a second sinusoidal signal and mixes the second sinusoidal signal and the input signal to generate a second mixed signal. The controller determines characteristics of the input signal based on the first and second mixed signals.

    Abstract: The disclosure features wireless energy transfer sources that include at least two source resonators and a power source, where: each of the at least two source resonators has a nominal impedance when a device resonator is not positioned on or near any of the at least two source resonators, the nominal impedances of each of the at least two source resonators varying by 10% or less from one another; and the at least two source resonators are configured so that during operation of the wireless energy transfer source, when a device resonator is positioned on or near a first one of the at least two source resonators: (a) the impedance of the first source resonator is reduced to a value smaller than the nominal impedances of each of the other resonators by a factor of 2 or more.
