Abstract
To communicate with a magnetometer (82) within a golf ball (20) used in a golf facility, an electromagnetic coil (30) is configured to supply pulsed signals to the magnetometer. A plurality of coils (30) are provided at different locations around the golf facility, and the pulsed signals are preferably coded so that the location of the golf ball is known.
Claims18
A golf facility comprising:
- a plurality of tee apparatus each of which includes:
- a support;
- an electromagnetic coil that is mounted on the support and transmits a unique identification code by generating a changing magnetic field;
- a cover plate that carries a marking for ball positioning;
- and
- circuitry that supplies electrical signals to the electromagnetic coil to generate the changing magnetic field;
- and
- a golf ball including:
- a magnetometer that:
- receives the unique identification code of one of the plurality of tee apparatus by detecting the changing magnetic field of the electromagnetic coil;
- transitions from a low-power state to a high-power state upon detection of the changing magnetic field of one of the plurality of tee apparatus;
- and
- upon receipt of the unique identification code, subsequently serves as a compass to monitor movement of the golf ball;
- and
- circuitry that identifies at which of the plurality of tee apparatus the golf ball is located based on the unique identification code.
