| Abstract: 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. |
