    摘要: A diagnostic system and method for an electric power steering system are provided. The diagnostic system includes a first microprocessor that determines a first relative position value indicating the relative rotational position of the rotatable shaft at the first time based on the signals from first and second position sensors. A second microprocessor determines a second relative position value indicating the relative rotational position of the rotatable shaft at the first time based on the signals from third and fourth position sensors. The first microprocessor determines whether the first relative position value is an acceptable value based on a difference between the first relative position value and the second relative position value.

    摘要: The present invention provides solid oxide fuel cells, solid oxide electrolyzer cells, solid oxide sensors, components of any of the foregoing, and methods of making and using the same. In some embodiments, a solid oxide fuel cell comprises an air electrode (or cathode), a fuel electrode (or anode), an electrolyte interposed between the air electrode and the fuel electrode, and at least one electrode-electrolyte transition layer. Other embodiments provide novel methods of producing nano-scale films and/or surface modifications comprising one or more metal oxides to form ultra-thin (yet fully-dense) electrolyte layers and electrode coatings. Such layers and coatings may provide greater ionic conductivity and increased operating efficiency, which may lead to lower manufacturing costs, less-expensive materials, lower operating temperatures, smaller-sized fuel cells, electrolyzer cells, and sensors, and a greater number of applications.

    摘要: Many variables in processes such as those using turbocompressors and turbines must be limited or constrained. Limit control loops are provided for the purpose of limiting these variables. By using a combination of closed loop and open loop limit control schemes, excursions into unfavorable operation can be more effectively avoided. Transition between open loop and closed loop may be enhanced by testing the direction and magnitude of the rate at which the limit variable is changing. If the rate of change indicates recovery is imminent, control is passed back to the closed loop limit control function.

    摘要: An in-tank fuel supply unit self cleans the mesh filter of the primary fuel pump, thereby permitting smaller mesh sizes to decrease pump wear and increase the life of the pump. Generally, the in-tank fuel supply unit includes a reservoir, an auxiliary fuel pump, a primary fuel pump and a filter. Fuel exiting the auxiliary fuel pump outlet is directed towards the filter to wash debris from the filter. Preferably a swirling flow is generated within the reservoir, or the system in run in an overflow condition to assist in the self cleaning of the fuel filter.
