Title: Inductive circuit sensor system and method

Patent ·
OSTI ID:1840297

An inductive circuit sensor system and method for monitoring an electromagnetic signal path through a circuit is shown. A protected element or door is movably positionable adjacent to the stationary element or frame in a monitored position. A conductive sensor pattern element is connected to a pair of inductive coils. The pattern element is a conductive wire traversing a predetermined cross-section of the door. The frame has a transmitting coil in communication with a microcontroller. The transmitting coil is coupled with the first coil and a receiving coil is coupled with the second coil. The transmitting coil receives a signal from the microcontroller and couples the signal to the pattern element. The signal is in communication with a receiving port on the microcontroller. The microcontroller is programmed to compare the signal from the transmit port with the signal at the receiving port.
