Optical aim-training apparatus 10 (FIG. 1) for a rifle 20, or the like comprises a CRT displaying a target image on a scanned line raster. The rifle is simulated and has photo-detection device 21 contained in a housing 22 located adjacent the barrel 19. The photodetection device has a detection axis 23, aligned parallel with the rifle bore axis, which 23 intersects the screen at detection point 34. The rifle sighting device has a sightline also parallel to the bore axis and detection axis intersecting the screen at aim point 33. The offset between aim and detection points is determined by a calibration procedure and when aim is taken at a target image and the trigger depressed a marker region of raster 29, displaced from the image by the calibration offset, is brightened temporarily. A series of light pulses due to scanning of the marker region raster is detected and the screen location of the center of the detector field of view i.e. detection point 34, found. With said calibration offset this enables the actual aim point to be found without masking the target image screen brightening necessary to enable photodetection. A further detection point (FIG. 5) may be defined and the relationship between the two detection points used to monitor the orientation of the rifle about the bore axis and its distance from the screen.

The present invention concerns golf teaching apparatus in which a student swings a golf club over a target area having photocells. The outputs from the photocells are analyzed and displayed to give an indication of yardage and faults in the student's swing. In particular the photocells include two transverse arrays which are partially darkened by a passing golf club shadow so that the relationship between the number of photo devices darkened in the upstream array to those darkened in the downstream array is an indication of golf club direction. The invention is directed to concerning the error which arises if the two arrays are not located for maximum accuracy. Thus in accordance with the invention the two arrays are located symmetrically on either side of a line tangential to the target ball and at right angles to an ideal path of a golf club head when it impacts the target ball.

A target system is disclosed which is responsive to and indicative of the ts and areas of near miss of laser light pulses that have been shot from a laser weapon aimed at the target system, be it a simulated gun or other device, by a marksman. In addition to the bullseye indicia on the face of the target system, the target system comprises a quadrant arrangement of laser light detectors that are located on the front of the target system in such manner as to permit them to sense the laser light pulses. The detectors are connected in unique combination with data processing channels, programmed timers, a preprogrammed read only memory logic circuit, and an array of lights disposed around and near the perimeter of the target face. The latter mentioned lights light up in accordance with the approximate location of the hits of the laser light pulses relative to the bullseye of the target face, thereby indicating either a hit or the direction of a near miss to the marksman.

A training device for simulated anti-armor weapons system utilizes a microcessor system to perform a number of functions including solving dynamic flight equations of a simulated missile and determining the gunner's aiming error. A miniature terrain board having a miniature target with an infrared source provides the aim point for a gunner using a simulated weapon launcher. An infrared sensing device mounted in the weapon provides input to the microprocessor while a CCTV provides an instructor with a gunner's view. Sound, visibility, and recoil associated with weapons use are simulated by peripheral devices under the control of the microprocessor. The gunner's aiming error and view are displayed in real time on an instructor's console which provides for instructor input and recording of gunner performance.

A weapon training simulator employing a computer with associated memory and software. A simulated weapon with simulated recoil provides hammer fall signals to initiate computation. A quadrature sensor mounted on the weapon generates target position signal based on point sources located on simulated targets. The computer generates real time, video displays and replays and prints out displays of target aim, hit and other information while controlling recoil simulation, providing shot sound and generating speech directions and commands.
