Abstract
An interference sensor device is disclosed. The interference sensor device includes a first conductive plate, a second conductive plate aligned parallel to the first conductive plate, a non-conductive matter between the first conductive plate and the second conductive plate and a coil electrically coupled to the first conductive plate and the second conductive plate.
Claims9
An interference sensor device, comprising:
- a signal adder having two input ports and two output ports;
- a first conductive plate;
- a second conductive plate aligned parallel to the first conductive plate;
- a non-conductive matter between the first conductive plate and the second conductive plate, wherein the first conductive plate is coupled to a first input of a first amplifier and the second conductive plate is coupled to a second input of the first amplifier, wherein an output of the first amplifier is coupled to a first of the two input ports of the signal adder;
- and
- a sensor coil having two ports each electrically coupled to a first input and a second input of a second amplifier, wherein an output of the second amplifier is coupled to a second of the two input ports of the signal adder.
