Abstract: An electrical power generator is characterized by a plurality of system parameters. The generator includes a controller for protecting the generator. The controller obtains data from which a present operating point of the generator and a power generating capacity of the generator can be determined. The controller further monitors data indicative of at least one system parameter as a function of time to detect an abnormality in a value of the system parameter. The controller then categorizes a type of event that caused the abnormality with respect to the data indicative of the system parameter as a function of time, the present operating point, and the power generating capacity. Finally, the controller provides a response for addressing the type of event that caused the abnormality.

Abstract: A food processing appliance for processing food stuff including a housing and an electric motor mounted within the housing. A bowl lid is removably mountable over the bowl. The bowl is mounted to the housing and the bowl lid is mounted over the bowl in a working position. A control mechanism is mounted to the housing and is operatively connected to the motor. A sensor is positioned on the housing and transmits a signal when the bowl and bowl lid are in the working position. An indicator includes a transparent plate mounted around a periphery of the control mechanism. The indicator visually indicates that the bowl and bowl lid are in the working position upon receiving the signal from the sensor such that power can be provided to the electric motor.

Abstract: The output voltage generated by permanent magnet generator (PMG) is regulated by controlling a buck/boost voltage applied to selected sub-coils within the PMG. The PMG includes a number of stator coils that are each divided into a number of sub-coils. A buck/boost voltage source generates a buck/boost voltage, and a controller connected to monitor the output voltage generated by the PMG selectively applies the buck/boost voltage to selected sub-coils based on the monitored output voltage. In this way, the controller is able to regulate the output voltage by selectively controlling the buck/boost voltage applied to the selected sub-coils.

A variable cavitating venturi may be arranged within the throat to vary the area and adjust the flow rate through the venturi. The cavitating venturi can also be used at the fuel nozzle to further simplify the fuel delivery system.
