APPARATUS AND METHODS TO TRACK SPORT IMPLEMENTS
First Claim
1. An apparatus comprising:
- a first coil to generate a first magnetic field having a first vertical component with a zero magnitude along a first line of interest;
a second coil partially overlapped with the first coil, the second coil to generate a second magnetic field;
a sensor to measure a magnitude of the first magnetic field in the first line of interest; and
a processor to determine an object of interest has crossed the first line of interest based on the magnitude of the first magnetic field measured by the sensor.

Abstract
Examples are disclosed to track sport implements and/or objects of interest. An example apparatus includes a first coil to generate a first magnetic field having a first vertical component with a zero magnitude along a first line of interest and a second coil partially overlapped with the first coil, where the second coil is to generate a second magnetic field. The example apparatus also includes a sensor to measure a magnitude of the first magnetic field in the first line of interest and a processor to determine an object of interest has crossed the first line of interest based on the magnitude of the first magnetic field measured by the sensor.
