    Abstract: A gapped resonant current transformer that has a pre-determined gap in a split-core. The invention eliminates the need for a magnetic flux shunt between the primary and secondary windings. Further, the sensitivity to the clamping force holding the two halves of the split-core is reduced as well as temperature effects on the core. Finally, excess heat is removed from overload (saturation) by circulating power back into the line.

    Abstract: A liquid level sensor that provides digital signal processing for transforming a magnetic field into a continuous linear output signal that corresponds to the level of liquid within a vessel that is being monitored. The invention uses 3D field sensors for decompensating unwanted interference caused by electric drives or the earth's magnetic field or other magnetic fields caused wires or magnets. The sensor can also be combined with 3D accelerometer to optimize compensation of unwanted interference. The accelerometer always provides the center of the earth so that an angle of deflection of the liquid versus the horizontal can be determined and correct any faulty measured value of the liquid level. The invention is highly robust yet is low cost to manufacture.

    Abstract: A current detecting and switching apparatus that provides automatic coupling of internal components of an appliance to varying supply voltage sources to prevent components from operating at something other than their intended power rating. The switching apparatus provides automatic coupling to multi-rated internal components of the appliance instead of providing a voltage specific appliance pre-wiring of specific connections of a multi-voltage component.
