Personal golfing assistant
First Claim
1. An apparatus for measuring and displaying distances between a golfer and an object on a golf course comprising:
- a handheld computing device;
a GPS device connected to said handheld computing device;
said GPS device producing measured location information corresponding to the location of said GPS device;
means for modifying said measured location information to obtain corrected location information;
means for determining a distance between the GPS device and said object by using said corrected location information and stored information concerning the location of said object; and
wherein said handheld computing device displays said distance.

Abstract
A personal golfing assistant system is comprised of software running on a PDA that is attached either directly or remotely to a GPS receiver that enables the user to engage in a process of easily surveying and/or electronically capturing geophysical data pertinent to the game of golf such as the location of the center of the green, zones on the green, bunkers, water, trees, hazards, etc. Software allows a golfer to use a handheld PDA/GPS unit in the course of play to mark a ball location automatically and/or determine the distance to various targets and avoidance objects and add additional objects. The system can send a set of parameters tailored for a specific course to a real time tunable GPS to adjust for optimal performance and can adjust measurements to compensate for changes in environmental conditions. Software analyzes ball location, distance, club and other information and generates useful statistics.

13. A method of obtaining and processing location values for a desired point on a golf course comprising the steps of:
-
obtaining reference point GPS information using a handheld GPS device reflecting a measured location of a reference point;
comparing said GPS information with true location information for said reference point using a handheld computing device and generating one or more correction values based on said comparing step; and
obtaining desired point GPS information using a handheld GPS device reflecting a measured location of said desired point; and
applying said one or more correction values to said desired point GPS information using a handheld computing device to generate corrected location information for said desired point.

-
17. A method for measuring the distance between points on a golf course comprising the steps of:
-
storing location values for multiple targets on a golf course based on GPS measurements taken on a first date;
generating corrected location values based on a difference in environmental conditions on said first date and a second date;
on said second date, obtaining location information concerning a desired point using a GPS device; and
computing the distance between said desired point and one of said multiple targets using said corrected location values and said location information concerning said desired point.

21. An apparatus for measuring and displaying distances between a golfer and an object on a golf course comprising:
-
a first handheld computing device;
a GPS device connected to said handheld computing device;
said GPS device producing measured location values corresponding to the location of said GPS device;
means for generating error correction values to be applied to said measured location values; and
means for transmitting said error correction values to a second handheld computing device. - View Dependent Claims (22, 23, 24, 26, 27, 29, 30)

25. A personal golfing assistant comprising:
-
a handheld computing device having a display;
a GPS device connected to said handheld computing device;
means for computing multiple approximate distances traveled by a golf ball after being hit by a golfer using one or more golf clubs, said multiple approximate distances computing means including said handheld computing device and said GPS device;
means for selectively storing said approximate differences;
means for selectively storing information representing the identity of each golf club used by said golfer;
means for determining the average distances travelled by a golf ball when hit by said golfer on a club by club basis;
means for determining a recommended club to be used by said golfer based at least in part on said average distances; and
means for displaying information on said display representing said recommended club.

-
28. A personal golfing assistant comprising:
-
a handheld computing device having a display;
a GPS device connected to said handheld computing device;
means for calculating the average distances travelled by a golf ball hit by a golfer on a club by club basis; and
means for displaying on said display a suggested club to be used by said golfer based on a distance input to said handheld computing device.
