POSITION LOCATION SYSTEM AND METHOD
First Claim
1. A position location system for determining a position of a player within a playing area, wherein the system includes a wireless communication arrangement, a wireless-enabled projectile and a target region, wherein:
- the wireless communication arrangement is implemented as a wireless terminal at substantially a single spatial location relative to the playing area;
the wireless-enabled projectile includes a wireless interface for communicating with the wireless terminal to exchange data therewith, and a sensing arrangement for sensing a first distance travelled by the wireless-enabled projectile relative to the playing area;
the system includes a computing arrangement for receiving a wireless signal from the wireless-enabled projectile, wherein the computing arrangement is operable to process the wireless signal to determine a second distance of the wireless-enabled projectile from the wireless terminal, and wherein the computing arrangement is operable to receive data from the wireless-enabled projectile indicative of a start time (t0) of a trajectory of the wireless-enabled projectile, an end time (t1) of the trajectory of the wireless-enabled projectile, and the first distance travelled by the wireless-enabled projectile as sensed by the sensing arrangement; and
the computing arrangement is operable to process data indicative of the first and second distances as a function of the start time (t0) and the end time (t1) to determine therefrom the position of the player within the playing area.

Abstract
A position location system for determining a position of a player within a playing area includes a wireless communication arrangement, a wireless-enabled projectile, a target region, and a computing arrangement. The projectile includes a wireless interface for communicating with the wireless terminal to exchange data, and a sensing arrangement for sensing a first distance travelled by the projectile relative to the playing area. The computing arrangement receives a wireless signal from the projectile, and processes the wireless signal to determine a second distance of the projectile from the wireless terminal. The computing arrangement receives data from the projectile indicative of a start and end time of a trajectory of the projectile, the first distance travelled by the projectile as sensed by the sensing arrangement and processes the data as a function of the start and end time to determine the position of the player within the playing area.
