An electrical system for powering electrical circuits has a current varying device electrically coupled to a power consuming device and an exhaustible power source connector. A first microprocessor receives power through the exhaustible power source connector and communicates with a first signal modulator and demodulator. An inductor is responsive to the current varying device from which power is drawn. A second microprocessor receives power from the inductor and communicates with a second signal modulator and demodulator. The second signal modulator and demodulator receive power from the inductor. |
