Electronic marker stakes for sports fields
First Claim
1. An electronic marker stake system for locating reference points in a field to be used for multiple sports, comprising:
- a first set of marker stakes adapted to be placed in the ground and removably receive first field boundary indicators, wherein said first set of marker stakes emit a first signal associated with a first field sport; and
a second set of marker stakes adapted to be placed in the ground and removably receive second field boundary indicators, wherein said second set of marker stakes emit a second signal associated with a second field sport, and at least one of said first and second sets of marker stakes have individually assigned identification numbers which indicate a sequence that defines a field boundary.

Abstract
A marker stake for locating a boundary reference point on a sports field can be buried and out of sight when not in use, and then quickly located using an electronic receiver which detects a signal emitted by an electronic marker in the marker stake. Various field boundary indicators can be removably attached to the marker stake. The stake may be embodied in a cylindrical body constructed of a moldable polymer with a socket at one end for receiving a pin or post of the field boundary indicator, and the electronic marker embedded inside the body. The electronic marker may be a passive LC marker tuned to a frequency associated with a known field sport. Different sets of such marker stakes tuned to different frequencies may be used to mark and relocate reference points for multiple sports played on the same field.
