An apparatus for and method for powering a microprocessor from energy received from a fuel burner at ignition. A thermopile receives heat energy from the flame and generates electrical power to enable operation of a microprocessor. This electrical power is converted to a higher voltage by a special low voltage DC-to-DC converter which operates shortly after ignition. The special low voltage powers a second DC-to-DC converter which in turn powers the microprocessor.

Why it's free to use
- Filed November 13, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 13, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 13, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
