  • Systems for indirect average current measurement
    Patent number: 9621018
    Abstract: One example of the invention relates to a power system. The power system can include a switching power converter configured to convert an input voltage to an output voltage for providing power at an output thereof to which a load is connectable. A measurement system can include measurement circuitry configured to measure an average of an accessible current in the power converter during both continuous and discontinuous modes of operation and derive an average measurement of another current in the power converter based on timing control signals used to control operation of the power converter.
    Type: Grant

  • Turbine engine fan speed monitor
    Patent number: 4954974
    Abstract: A turbine fan speed monitor for use with an aircraft engine which monitors actual fan speeds for each of a plurality of aircraft engines. The apparatus also input instantaneous values of total air temperature, pressure altitude, altitude rate, and the position of the wheels. The fan speed monitor calculates an overspeed limit value for the turbine fan as a function of each of the total air temperature, pressure altitude, altitude rate, and position of the wheels data and indicates when the actual fan speed exceeds the overspeed limit value for each monitored engine. The monitor warns the pilot of calculated overspeed conditions that he can control by throttle manipulation. Engine life is related to the calculated speeds at take-off, climb and cruise. The monitor keeps a record of the time and duration of these instances when the actual fan speed exceeds the overspeed limit for any engine.
