Patents by Inventor Todd Slater

Todd Slater has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods and systems of diagnosing fuel injection system error
    Patent number: 7252072
    Abstract: A fueling system for an internal combustion engine. The system has a voltage booster and a fuel injector. The voltage booster is operatively coupled to the injector to selectively drive the injector. A method includes determining compliance of a booster voltage with a threshold. The method further includes diagnosing fuel system error based upon the determining compliance.
    Type: Grant

  • Techniques for determining turbocharger speed
    Patent number: 7127892
    Abstract: One embodiment of the present invention includes an internal combustion engine with a turbocharger. The turbocharger includes a compressor with an outlet coupled to an intake of the engine and a turbine coupled to an exhaust manifold of the engine. A a turbocharger speed estimate is determined from engine speed and a ratio between inlet and boost pressure for the compressor. The turbocharger speed estimate is further adjusted as a function of compressor boost pressure variation with time.
