Abstract:
A device is provided. The device includes one or more of a radially-wound coil, a hall-effect sensor, a power source, and a control circuit. The radially-wound coil is configured to produce a first magnetic field in response to a DC current applied to the coil. The hall-effect sensor includes a sensor output that indicates proximity of a magnet to the hall-effect sensor. The magnet produces a second magnetic field and the sensor output indicates proximity in response to a sum of a strength of the first magnetic field and a strength of the second magnetic field at the hall-effect sensor exceeds a trip level. The radially-wound coil is in fixed proximity to the hall-effect sensor. The power source is coupled to the hall-effect sensor and is configured to provide power that alternates between on and off voltages to the hall-effect sensor. The control circuit is configured to receive the sensor output and in response provide the DC current to the radially-wound coil in order to control a polarity of the first magnetic field to detect the magnet.

Claim (Index 13):
The system of  claim 8 , wherein the control circuit biases the first magnetic field through the DC current to a bias level just below the trip level, wherein the strength of the second magnetic field depends on characteristics of magnets to be detected, the characteristics comprising the strength of the magnet, an orientation of the magnet to the radially-wound coil, and a distance between the magnet and the hall-effect sensor.
