Abstract
Abstract Apparatus for simulating the playing of golf includes a tee area from which a player may drive a golf ball toward a curved target screen in front of the tee area. Three arrays of optical sensing devices are positioned to gather data as to the time and horizontal location at which a driven ball passes through each of three corresponding planes spaced apart between the tee area and the screen, and the horizontal location at which the ball rebounds from the screen through the plane closest to the screen. The sensing devices detect the passage of balls through the planes by detecting the reflection of infrared light from the balls. The infrared light is produced by an infrared light source and directed through the space through which the balls travel. A first and second ones of the planes are vertically disposed between the tee area and the screen and a third plane is disposed to extend from near the top of the second plane to near the bottom of the screen. With the data from the sensing devices, computer apparatus produces an estimate for display of the distance of travel and ultimate resting position the driven ball would have if allowed free flight. Use of sensing devices for detecting passage of a driven ball through three different planes and for detecting the rebound angle of the ball from the screen enables determination of the amount of hook or slice a driven ball would have. A television camera is positioned on one side of the tee area, and a grid pattern is positioned on the other side to provide a background and gauge against which movement of a player photographed for instant replay may be measured.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
Apparatus for simulating the playing of golf comprising a support defining a tee area from which a golf ball may be driven by a player utilizing a golf club, sensor means for detecting the time and horizontal location at which a driven ball passes through each of three planes spaced apart in the direction of travel of the ball, and logic means responsive to said sensor means for producing an estimate of the distance of travel and ultimate resting position the driven ball would have if allowed free flight.
Claim 2
Dependent Claim
89 words
Apparatus for simulating the playing of golf comprising a support defining a tee area from which a golf ball may be driven by a player utilizing a golf club, sensor means for detecting the time and horizontal location at which a driven ball passes through each of three planes spaced apart in the direction of travel of the ball, and logic means responsive to said sensor means for producing an estimate of the distance of travel and ultimate resting position the driven ball would have if allowed free flight.
Claim 3
Dependent Claim
67 words
Apparatus as in claim 1 further including light means for directing light through the space through which a ball will travel when driven from the tee area, and wherein said sensor means includes three arrays of photosensors, each for receiving light reflected from a driven ball as it passes through a corresponding one of said planes, and for producing a ball-indication signal upon receipt of such light.
Claim 4
Dependent Claim
55 words
Apparatus as in claim 2 wherein each of said arrays include a plurality of photosensors positioned generally in a row to be activated by reflected light from a driven ball, said photosensors being dimensioned and spaced apart a distance to cause at least two adjacent sensors to be activated by light reflected from a ball.
Claim 5
Dependent Claim
73 words
Apparatus as in claim 3 wherein said light means is disposed above the space through which a ball will travel so as to direct light downwardly to three areas spaced apart in front of the tee area and over which a driven ball will travel, and wherein said arrays of photosensors are disposed generally adjacent the light means, each for receiving reflected light from the direction of a different one of said areas.
Claim 6
Dependent Claim
52 words
Apparatus as in claim 4 wherein said light means is adapted to produce infrared light, wherein said arrays of photosensors are adapted to detect infrared light, and wherein said three areas include dark coloring on the upper surfaces thereof to provide contrast with the ball and to minimize reflection of infrared light.
Claim 7
Dependent Claim
34 words
Apparatus as in claim 2 wherein said logic means is adapted to produce said estimate only when all of the arrays of photosensors receive light within a predetermined period of time of one another.
Claim 8
Dependent Claim
99 words
Apparatus as in claim 6 further including a target screen disposed in front of the tee area for receiving balls driven from the tee area and from which balls will rebound, wherein first and second ones of said planes are vertically disposed between the tee area and screen and generally in parallel with each other, wherein a third one of said planes is disposed to extend from near the top of said second plane to near the bottom of said screen, and wherein said screen is curved in the horizontal direction about a point located in the tee area.
Claim 9
Dependent Claim
84 words
Apparatus as in claim 7 wherein the array of photosensors for receiving light in said third plane is adapted to produce a first ball-indication signal as a ball passes through the third plane to the screen and a second ball-indication signal as the ball rebounds from the screen through the third plane, and wherein said logic means is responsive to said first and second ball-indication signals for producing an estimate of the lateral displacement of the ball if the ball were allowed free flight.
Claim 10
Dependent Claim
102 words
Apparatus as in claim 1 further including a target screen disposed in front of the tee area for receiving balls driven from the tee area, projector means positioned to project images from changeable film frames onto the target screen for viewing by the player, film frames for said projector means, each frame having a scene of a golf hole taken from a different location spaced from the golf hole, and wherein said logic means is adapted to signal said projector means to project a scene representative of the location nearest the position the logic means estimated the driven ball came to rest.
Claim 11
Dependent Claim
147 words
Apparatus as in claim 9 wherein said projector means includes a lamp housing for containing a lamp and having an opening in one end thereof through which light may pass, a film guide disposed adjacent the lamp housing over said opening and comprising an elongate, generally rectangular casing open at both ends thereof to allow the threading of film through the casing, said casing having first and second openings in opposite sides thereof, said openings being positioned contiguous to the opening in the lamp housing to enable light to pass through the casing and thus through film threaded in the casing, said casing having a third opening near one end thereof, sprocket means disposed adjacent the film guide to drivingly engage through said third opening film threaded through said casing, and means for driving said sprocket means to thereby cause the film to move through the casing.
Claim 12
Dependent Claim

Dependent Claim
24 words
Apparatus as in claim 11 further including a foam material disposed under each of said sections and into which golf tees may be inserted.
