Abstract

A golf ball locating apparatus and a method of applying a reflective coating to the golf ball. The apparatus involves a handheld apparatus which locates a wayward golf ball and identifies its relative position to the handheld apparatus. The handheld apparatus is structured in two preferred embodiments: the first is a handheld apparatus that fits into a user'"'"'s pocket; the second is a shaft arrangement which has two extendable wings to form a "T" shape. The pocket sized embodiment has a forward facing window to direct a beam from the apparatus. The beam of radiation reacts with a clear coating on the golf ball and is sensed by the apparatus which then illustrates, via a display, the relative location of the golf ball. The "T" embodiment has antennas embedded into the wings which emit a field which are disturbed by the coating on the golf ball; lights associated with the antennas are illuminated to show the operator which antenna is in the closest proximity to the golf ball. The coating on the golf-ball is applied through a variety of techniques and preferably covers the entirety of the golf ball. One methodology uses an impregnated cloth to wipe the golf ball immediately prior to placing the ball in-play. This assures a coating on the golf ball during each play.

Claims

1. A golf ball locating combination comprising:

a golf ball;

means for applying a coating to said golf ball;

a handheld locating apparatus having,

means for sensing said coating on said golf ball, and,

an operator interface means for identifying a location of said golf ball relative to said locating apparatus,

wherein said handheld locating apparatus includes a shaft portion having an operator handle on a first end thereof and two hinged wing portions swivelly attached to a second end of said shaft portion, each of said hinged wing portions having antenna means for sensing said coating.

2. The improved golf ball locating combination according to claim 1 further including:

a) auditory means, mounted to said shaft portion, for emitting an auditory signal; and

,

b) control means, connected to said auditory means and each of said antennas in said hinged wing portions, said control means for monitoring the antenna means in each of said hinged wing portions and causing said auditory means to generate an auditory signal indicative of which antenna in said two hinged wing portions receives a stronger reflected signal.

3. The improved golf ball locating combination according to claim 2 wherein said control means include threshold means for inhibiting said auditory means until a signal from either of said antennas on said hinged wing portions exceeds a pre-selected level.

4. The improved golf ball locating combination according to claim 1 wherein each of said hinged wing portions contains N, N being an integer greater than 1, spaced apart antennas and N light emitting apparatus, and further including a control means connected to each of said antennas and each of said light emitting apparatus, said control means for activating one of said light emitting apparatus associated with an antenna receiving a strongest signal from said coating on said golf ball.

5. The improved golf ball locating combination according to claim 1 further including positional sensing means for disengaging said antennas within each of said winged portions when said winged portion is not in an extended position.

7. The improved golf ball locating combination according to claims 4 or 6 wherein said means for applying includes a liquid matter applied to said golf ball.

8. The improved golf ball locating combination according to claim 7 further including a fabric material impregnated with said liquid matter, and wherein said liquid matter is applied immediately before said golf ball is put in play by wiping said liquid matter onto said golf ball using said fabric material.

9. The improved golf ball locating combination according to claim 7 wherein said liquid matter substantially covers said golf ball.

10. The improved golf ball locating combination according to claim 9 wherein said liquid matter dries substantially clear.

11. The improved golf ball locating combination according to claim 10 wherein said liquid matter is reflective of a radiation at a selected frequency.

6. A handheld apparatus for locating golf balls having a coating thereon, said handheld apparatus comprising:

a) means for sensing said coating on said golf ball,

b) an operator interface means for identifying a location of said golf ball relative to said handheld apparatus,

c) means for emitting a signal being reactive with said coating,

d) means for applying a coating to a golf ball, and

e) the golf ball,

wherein said handheld apparatus is pocket sized and has a forward facing window for emitting said signal across a controlled range.

12. The handheld apparatus according to claim 6 further including a filter means disposed over said forward facing window for filtering signals reflected from said golf ball.

13. The handheld apparatus of claim 6 wherein

the sensing means is a CCD sensor,

the interface means includes a computer and a display that generates a locating light, and

the emitting means is an emitter that emits an array of light beams.
