  • the computer supplies a first input signal which is the horizontal signal received from the microswitches activated by detection from cords 33, 35, 37 or 39.
  • the computer also provides a second input signal, which by means of the photocell units 28, 29, 30, 31 and 32 and associated computer circuitry computes the approximate yardage of the golf drive.
  • the second input signal will be referred to as the vertical signal.
  • the operation of the circuitry activated by the vertical signal will be considered first.
  • Resistors 226 is related to ten yards of distance of a golf drive.
  • resistor 228 is analogous to a twenty-yard distance
  • resistor 230 is analogous to forty yards
  • resistor 232 is analogous to eighty yards
  • resistor 234 to one hundred yards
  • resistor 236 to two hundred yards.
  • golf drives ranging in distance from ten yards to four hundred and fifty yards may be simulated by this circuit. For example, if the computer concludes that a golf drive having a projected distance of two hundred thirty yards is made, the computed vertical signal would activate resisters 226-, 228 and 236.
  • Activation is accomplished by solenoid activation of the switches 23 8, 240, 242, 244, 246 and 248, respectively.
  • these switches bear against contact points 259, 251, 252, 253, 254 and 255.
  • Oppositely disposed are open contact points 256, 257, 258, 259, 260 and 261.
  • the purpose of this circuit is to provide an output resistance R1 as measured between the contacts 262 and 264.
  • the open position as shown in solid lines in FIGURE 4 illustrates a circuit having no resistances, since there is a resistance free-path for the current, namely along conductor 266 through the switch 238 and contact point 250 into the next conductor 268, thus bypassing the resistor 226. All of the corresponding switches and resistances are connected in parallel across respective conductors 269, 270, 271, 272 and 273, which also are connected to the contact 264.
  • the vertical input signal from the computer would cause the switches 238, 240 and 248 to break contact with points 250, 251 and 255, and 261.
  • the current path from contact 262 and through conductor 266 now includes resistors 226, 228 and 236, thus providing a value of R1 equal to the total of these three resistors.
  • R1 forms part of the Wheatstone bridge 274 as shown in FIGURE 5.
  • Contact 264 is grounded at 275, and contact 262. is connected to another variable resistance R2.
  • the other side of R2 is connected to contact point 276, which in turn is connected to the grid 278 of an amplifying tube 280 by means of conductor 282.
  • Contact 284 is interposed between fixed resistances R3 and R4, which complete the Wheatstone bridge.
  • a 12- volt alternating current is impressed between the contact 262 and 284.
  • the tube 280 has a plate 286 in series with a resistance 288 and a filament 290 having a resistance 29 2 and a capacitor 294 in parallel therewith.
  • a capacitor 296 and a resistance 298 are interposed between the capacitor 296 and resistance 2%.
  • the filament 308 is connected to a resistor 310 and parallel capacitor 312.
  • the opposite end of resistors 292, 298 and 310' and capacitors 294 and 312 are connected to a common conductor 314, which in turn is grounded at 316.
  • the plate 318 of the tube 304 is connected to a capacitor 320 and a parallel solenoid 322.
  • the far ends of resistor 288, capacitor 320 and solenoid 322 are connected to a common conductor 330.
  • the solenoid operates the switch 324 from the open position shown in FIGURE 5 to a closed position in which the contact 325 of the switch forms a closed circuit with contact 325 of conductor 328.
  • a ZOO-volt potential is impressed across conductors 330 and 314 as plate voltage.
  • the motor 64 is operated by a llO-volt alternating current potential, and in turn is connected to the resistance R2, which is the potentiometer 202, through the gearing 206 and 216 of the potentiometer shaft 204.
  • the motor is connected to the switch 324 by conductor 332, and to the -volt source by conductor 334.
  • conductor 332 at contact 336 is also connected to conductor 338 terminating in contact 340.
  • cond uctor 344, capacitor 346 and conductor 348 terminating at contact switch 350.
  • the contact switch 350 manually abuts the cam hub 208 and is manually operable thereby.
  • the reset relay 352 which includes a solenoid 354, causes switch 355 to move from contact 356 to contact 357, once again causing the motor circuit to close, and operating motor 64.
  • the operation causes the cam hub 208 to continue rotation until it returns to its initial or starting position, at which point switch'350 breaks contact with contact point 340 and the motor ceases operation until the cycle is repeated.
  • the same vertical input signal which drives the circuitry of FIGURE 4 also operates the circuitry shown in FIGURE 6.
  • This circuit is used to select a mask 166471 having an aperture sized according to the distance achieved by the golf drive, thus providing a more accurate simulation of size of the golf ball as it moves a specified distance from the simulated point of origin of the drive.
  • switches 360, 361, 362, 363, 364 and 365 normally positioned against ground contacts 366, 367, 368, 369, 370 and 371.
  • the switches are connected by conductors to solenoids 372, 373, 374, 375, 376 and 377.
  • All the masks have through apertures except the masks activated by solenoid 377 which has a single aperture.
  • the first five switches are keyed to approximate length distances and are individually activated as the information is received from the computer. Continuing the example previously mentioned with a drive of two hundred thirty yards, switch 363 will be closed to make contact with contact point 381, closing the circuit and activating solenoid 375. This causes mechanical movement of the arm and pivoting of respective masks to bring the appropriately sized smaller aperture in the alignment path of the light source, and the lens thus limits the size of the image projected upon the screen accordingly. During this period, the remaining masks are so positioned that the larger apertures therein lie in the light ray path.
  • the reset relay 352 is activated and causes switch 365 to contact point 383, thus activating solenoid 377 and causing the single aperture mask to position itself in the light ray path. Since there is no smaller aperture in this mask, the source of light will be completely blocked from the lens, thus eliminating the image from the screen during the resetting operation of the scanning projector.
  • the same relay switch activates the horizontal positioning circuit.
  • one or more of the resistors 384, 385, 386 and 387 are interconnected.
  • the switches 388, 389, 390 and 391 are normally positioned against ground contacts 392, 393, 394 and 395.
  • the opposite ends of the resistors are connected to a conductor 396 which is in series with the galvanometer 58.
  • the galvanometer is grounded at 398, completing the circuit.
  • Operation of the device 10 causes the reset relay to activate switch 355, moving it into contact with contact point 356.
  • the computer will activate one of the four switches, for example switch 388, causing it to come into contact with contact point 400.
  • This will cause a completed circuit containing resistor 384 in series with the galvanometer 58, As the galvanometer armature pivots, it will cause the mirror 56 to move accordingly for projection of an image in approximately a correct horizontal location, according to the angle of the golf drive.
  • the scanning projector 12 receives two input signals from the computer.
  • the first signal is the horizontal positioning signal which activates the circuit shown in FIGURE 7, which positions the mirror for horizontal location of the projected image upon the screen.
  • the second signal is the vertical or distance signal, and initially positions the masks as shown in FIGURE 6, and establishes the value R1.
  • R1 the circuitry in FIGURE 5 is activated, thus showing the vertical path movement of the ball image on the screen until the bridge is balanced and the motor circuit is opened.
  • the reset relay 352 is activated and the mask 171 is moved to cut ofi the light source and cause the image to disappear from the screen, and at the same time to close the motor circuit to cause the galvanometer to return to initial vertical position prior to the next drive.
  • Apparatus to provide a golf ball image-projection for a computer type golf game comprising: a scanning projector having a light source and projection lens, first input means providing a horizontal signal to said projector, second input means providing a vertical signal to said projector, masking means in said scanning projector between said light source and said lens, said masking means being activated by said second input means, and image scanning means in said projector including a horizontal positioning member and actuated by said first input means and a vertical positioning member actuated by said second input means.
  • said masking means includes a plurality of dual aperture masks activated by solenoids, said apertures including a substantially large diameter aperture to allow passage of light from said light source to said lens without obstruction thereof and a smaller sized aperture sized to form a specific spot image.
  • said horizontal and vertical positioning members include a galvanometer having a mirror pivotally mounted upon the armature thereof for pivotal movement about a horizontal axis upon said scanning projection.
