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 17):
The method of  claim 15 , further comprising:\n configuring the first magnetic field in an omnipolar configuration, comprising:\n symmetrically alternating the DC current between a positive and a negative value at a switching frequency in response to the sensor output does not indicate detection of the magnet and the DC current maintains the value it had just prior to the sensor output indicates detection of the magnet while the sensor output indicates detection of the magnet.
