Classification: CPC H | IPC H

Claim 12:
13. A method, comprising:
synchronizing, with a first clock, a time of day at a transmitter and a receiver;
synchronizing, with a second clock, a transmit time of a waveform signal from the transmitter with a receive time of the waveform signal at the receiver, the waveform signal including a message;
processing, with the receiver at a plurality of timed waveform reference locations, the waveform signal received, at an input of the receiver, from the transmitter, wherein processing the waveform signal includes:
setting, with one clock from first and second clocks, each timed waveform reference location from the plurality of timed waveform reference locations,
coupling a time location reference circuit to the one clock,
coupling a signal processing circuit to the time location reference circuit, and
wherein the signal processing circuit comprises a plurality of voltage integrator circuits, each voltage integrator circuit from the plurality of voltage integrator circuits includes at least a switch coupled to each of a respective timed waveform reference location and the input, a capacitor coupled to each of the switch and a ground to integrate at least one of a voltage and a current flowing through the switch from the input, and a diode; and

extracting, with the receiver, the message in a response to determining a presence of the message.
