Remote golf ball locator
First Claim
1. A method for obtaining accurate representations of distance from a golf ball to features of interest on a hole of a golf course including tee box, cup and pin locations, water hazards, sand traps, areas of rough adjacent fairway, and cart path, using a golf cart equipped with computerized navigation system including a display monitor, to assist golfers in playing the hole, wherein the golf course has been surveyed so that fixed positions of at least some of said features including the cart path and outline of the hole are known and are part of a map of the course stored in the database of the navigation system for selective display of the map or portion thereof on the cart monitor screen during play of the course, the navigation system having a capability to detect and indicate the real time position of said golf cart for display as a cart icon in the map on the monitor screen, said method comprising the steps of:
- providing in the map database a ball icon line substantially along the center of the hole from tee box to green approximating the longitudinal center-line of the hole;
displaying a ball icon distinct from the cart icon in the map on the monitor screen, to move along said ball icon line in juxtaposition with movement of the cart icon along the cart path;
calculating and displaying distance, in actual scale on the course, from the ball icon to the pin on the monitor screen; and
providing a capability to move the ball icon from the ball icon line to a position approximating the lie of a ball in play on the hole, whereby to display approximate actual distance therefrom to the pin.

Abstract
A method and system for obtaining accurate measurements of distance of a golf ball from features of interest on a hole of a golf course including tee boxes, cups, water hazards, sand traps, rough areas adjacent fairway, and cart path, uses a golf cart equipped with a computerized navigation system including a display monitor. Survey data for the course are stored in the navigation system database as part of a map of so that fixed positions of at least some of the features of the course, including the cart path and outline of the hole of the computerized navigation system, can be selectively displayed in the map or portion thereof on the cart monitor screen during play of the course. The navigation system has a capability to detect and indicate the real time position of the golf cart as an icon on the course map displayed on the monitor screen, and has, in its database, a ball icon line approximating the longitudinal center-line of the hole. A ball icon is established distinct from the cart icon for display in the map on the monitor screen, and is arranged to move along the ball icon line in unison with movement of the cart icon along the cart path. Distance measurements are enabled and displayed from the ball icon to features on the map when the features are respectively selected by a pointer on the monitor display. A positioning device is provided to move the ball icon from the ball icon line to approximate the position of a ball in play on the hole to measure distance to a selected feature.

9. Apparatus for obtaining accurate representations of distance from a golf ball to features of interest on a hole of a golf course including tee box, cup and pin locations, water hazards, sand traps, areas of rough adjacent fairway, and cart path, using a golf cart equipped with computerized navigation system including a display monitor, to assist golfers in playing the hole, wherein the golf course has been surveyed so that fixed positions of at least some of said features including the cart path and outline of the hole are known and are part of a map of the course stored in the database of the navigation system for selective display of the map or portion thereof on the cart monitor screen during play of the course, the navigation system having a capability to detect and indicate the real time position of said golf cart for display as a cart icon in the map on the monitor screen, comprising:
-
means for storing in the map database a tracking line substantially from tee box to green approximating the longitudinal center-line of the hole; means for displaying a ball icon for movement along said tracking line in juxtaposition with movement of the cart icon along the cart path on the monitor screen; means for calculating and displaying distance, in actual scale on the course, from the ball icon to the pin on the monitor screen; and a positioning device for moving the ball icon from the tracking line to a position approximating the lie of a ball in play on the hole, whereby to display approximate actual distance therefrom to the pin. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of providing a golf course position and distance system with the capability to indicate distance from a golf ball in play rather than from a golf cart that utilizes the position and distance system, wherein the golf cart is equipped with a monitor for displaying a map of the course or portion thereof being played, and for further displaying a depiction of the real time position of the cart on the map to aid the cart user in playing the course, and wherein the display includes a pointer for designating a feature of the course including a cup or pin, hazards, traps, fairway, green, rough, cart path, and outline of a hole being played incorporated in the map for which distance from the cart is to be displayed on the monitor screen, said method comprising the steps of:
-
displaying a depiction of a golf ball that tracks, along a line running substantially the length of the hole from tee box to green and substantially parallel to at least one side boundary of the hole, the movement of the cart depiction along the hole, so that the ball depiction remains on the tracking line substantially alongside the cart depiction on the monitor screen as play proceeds along the hole, and from which distance is calculated to those of the features selected with the pointer; and enabling selective repositioning of the ball depiction off the tracking line to approximate the lie of an actual golf ball in play, to display the approximate actual distance from the golf ball, rather than from the cart, to a selected feature on the monitor screen. - View Dependent Claims (16, 17, 18, 19, 20)
