1. An apparatus comprising:
- a first coil arranged in a first loop that defines a first portion of an opening of a sporting goal;
a second coil arranged in a second loop that defines a base of the sporting goal, at least a portion of the second coil defining a second portion of the opening of the sporting goal, the first coil and the second coil to be energized simultaneously to generate a magnetic field;
at least one sensor to measure a change in the magnetic field associated with the first and second coils as a sport implement moves within or into the opening of the sporting goal; and
a processor to determine a position of the sport implement based on the measured change of the magnetic field.

Abstract
Methods and apparatus for high speed location determinations are disclosed. An example apparatus includes at least two coils arranged along a zone of interest to generate a magnetic field, and a sensor to measure a change in the magnetic field associated with the at least two coils as an object of interest moves within or into the zone of interest. The example apparatus also includes a processor to determine a position of the object of interest based on the measured change.

11. A method comprising:
-
simultaneously energizing first and second coils to generate a magnetic field, the first and second coils arranged along a zone of interest of a sporting goal, the first coil arranged in a first loop that defines a first portion of the zone of interest of the sporting goal, the second coil arranged in a second loop that defines (1) a base of the sporting goal and (2) a second portion of the zone of interest of the sporting goal; determining a change of the magnetic field associated with the first and second coils as a sport implement moves into or within the zone of interest; and calculating, by executing instructions with at least one processor, a position of the sport implement based on the determined change of the magnetic field. - View Dependent Claims (12, 13, 14)
