Abstract: An electronic computer game and method includes a matrix of 25 LED's (light emitting diodes) and two sets of push button switches positioned on opposite sides of the matrix. Each set of push buttons comprises a group of five push buttons corresponding to the five rows of the matrix and a group of five push buttons corresponding to the five columns of the matrix. Each set of push buttons is arranged so that the ten fingers of a player may be placed on the push buttons and any one of the LED's in the matrix may be rapidly selected by either player by simultaneous actuation of one push button in each of his groups. A game selector switch may be moved to select one of a number of games of action, reaction or strategy each of which is controlled by a microprocessor which stores selection of LED's by each player, sets up random patterns on the matrix which are randomly altered, keeps track of each player's score and provides audible and visual signals informing the players of the progress of the game, etc.

Abstract: An electro-optic infantry weapons training system for simulating the firing f a quintet of weapons at a visual target which appears upon a screen. A quintet of trainee riflemen, each of whom is holding a weapon, aim and fire the weapons at the visual target. A visual projector projects upon the screen a background scene including the visual target, while an infrared projector simultaneously projects upon the screen an infrared target. Each weapon includes a sensor element for sensing the infrared target whenever the weapon is correctly aimed at the visual target. The sensor elements are connected in a unique combination with sensor circuits, enable circuits, and an interface circuit so as to provide to a microprocessor computer and an eight-bit microcomputer data words which indicate whether each of the quintet of trainee riflemen have scored a hit upon the visual target.

Abstract: A target shooting apparatus including an operator controlled simulated gun which projects a light beam of short duration toward a target each time the trigger is actuated. The simulated gun must be cocked between each "shot" which also resets a recoiling mechanism to give a true to life operational effect to the gun. The target includes a frame fronted by a simulated fence on top of which a plurality of objects, such as bottles, tin cans, and the like may be placed. A target impeller is provided on the frame in proximity to each of the objects so that, when actuated, the impeller will cause physical movement of the associated target knocking it off of the frame. The target impellers are actuated by a control mechanism, as a photo transistor therein senses the proper alignment of the light beam from the gun through one of a plurality of apertures located on the frame below each of the objects.

Abstract: An electronic bingo game is disclosed in which a memory is provided for storing all of the numbers called in a last set until the current set is completed and the next set begun.

A preselectable time interval is provided to determine the rate at which the bingo numbers are called. A true random number selection process is provided to select the bingo numbers called. A randomly selected seed number is provided at the start of each set, and the seed number used in each random selection for that set. Additional memory is included for storing the game patterns that will be used in each set, and each pattern will automatically be called up and displayed to the players as each new set is begun.

Abstract: A capacitive sensing device for detecting the presence of conducting and nonconducting objects with the distance between sensing tip and object remaining nearly constant regardless of their size or mass is disclosed. The device is particularly useful with the camera optical probe of an aircraft simulator for training pilots, and is mounted on the camera probe such that it generates a capacitance at its output which varies with the distance between the camera probe and objects on a terrain model board as the probe travels about the model board. Thus, if the optical probe approaches too close to an object, (especially an object outside the field of view of the pilot trainee) it generates a control signal to prevent the optical probe from crashing into such an object.

Abstract: 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.

Abstract: A golf putting game which includes a housing having a horizontally elongated opening into which a standard golf ball can be putted. Horizontally spaced sensors positioned lengthwise of the opening within the housing sense the lateral position of a ball entering the opening. The sensors controlling a numerical display indicate a score based on the position of the ball laterally of the opening. A back plate stops the ball within the housing, and a sensor determines the force with which the ball strikes the back plate. The indicated score is modified if the force on the back plate exceeds an acceptable level. Successive groups of balls can be putted into the opening and the score for each ball within the corresponding ball in the successive groups can be accumulated and individually displayed to permit a number of players to play the game at the same time.

Abstract: An electronic simulated football game includes provision for displaying and moving a multiplicity of offensive players on a display panel that includes an array of light-emitting diodes in response to commands entered from a keyboard to an operational circuit that controls the display. The provision of more than one offensive player affords the possibility of simulating blocking and passing, provisions for which are made in the operational circuit. Additionally, the operational circuit controls the display to provide and move a symbol representing a football during passing and kicking plays. Finally, status information, such as the score and the down number, is displayed on the same part of the display panel as that on which play action is shown.

Abstract: An electromechanically controlled board game for two players, each of which has a set of playing pieces which are advanced on a board in rank or file increments to attack pieces of the opposing player. The pieces are so configured that the relative value of each piece is visible only to the holder of the piece during play. An attacking piece is compared in value with the piece attacked by comparing a four bit code assigned to each piece with a corresponding code assigned to the piece attacked. The lower valued piece is considered captured, and is retired without disclosure of its relative value to the opposing player. Each side has one piece designated "flag" the object of the game being to capture the flag of the opposing side.

Abstract: An electronic game is provided having a playing field including an array of individually operable and selectively illuminated field array positions on which a game player attempts to maneuver a movable object over selected ones of the field array positions and actuate selected field array positions in accordance with the rules of the game. The player maneuvers the movable object by tilting or positioning of the playing field and game device with respect to a horizontal plane. The electronic game utilizes a microprocessor to control the progress of the game, to selectively illuminate playing field positions, to monitor the actuated field positions and to control the output of indications to the game player as to the progress of the game and the game player's score.

The "player" is advanced in response to another manual input a distance determined by the segment so illuminated. Game control and game status is under control of a processor using probabilities to determine game events. In the embodiment illustrated, the game is in the form of a baseball game with the segment depicted on a baseball diamond.

Abstract: A number of moving objects and stationary playfield objects are generated on a video display screen by sharing memory and circuitry on both a physical and time-share basis. Video graphics data for playfield and motion objects is stored in a read-only memory (ROM). An object attribute memory, which may be updated at any time, is scanned during each horizontal retrace interval to provide information used to selectively read moving object video data from the ROM and assemble and store a complete horizontal line of moving object video graphics data in a separate staging memory. During active scan time of the horizontal video display line, the assembled line of moving object video data is accessed from the staging memory and communicated to the display screen via appropriate video circuitry to produce the video of the moving objects.

Abstract: An electronic maze game comprising a maze which is stored electronically in the memory of a microcomputer, a four bar display which indicates if there is a wall or an opening immediately above, below, right or left of the player's present position, and four push buttons which permit the player to make a move from his present position to the adjacent position lying above, below, to the right or left, provided that such move is not blocked by a wall. A number of different mazes are stored in the game, and the player may choose to play a "beginner", "intermediate" or "advanced" game, or repeat the last game played. A two digit display tells the player at the beginning of the game the minimum number of moves required to transit the maze, and during play of the game, the number of moves the player has made.

Abstract: A game apparatus is disclosed having a one-dimensional array of LED's which are sequentially activated in first and second sweep sequences which proceed toward first and second goal indicators, respectively. First and second buttons are provided which operate to reverse the first and second sequences, respectively, and the object of the game is for each player to operate his button before the appropriate sweep sequence causes his goal indicator to be activated. The rate of each sweep is variable and a player can select a higher sweep rate for his opponent by delaying his reaction until a relatively later time in the sweep sequence. The score is displayed on the same indicators as are used to play the game, and successively higher scores correspond in sequence to the sequence in which the indicators are activated during play.

Abstract: The game is characterized by a complicated and dangerous looking bomb-like housing which is equipped with a four-by-six keyboard under a hinged transparent cover. A pair of alternately flashing red incandescent lamps illuminate the keyboard. When the cover is opened, exposing the keyboard, the lamps may begin to flash or pulsate and the rate of flashing of the lamps may be increased and a fuse sound is produced which starts out at a relatively low pitch and gradually over a preselected time period increases in pitch to the point where it is obvious that an inevitable "blowup" will occur. The object of the game is to prevent the bomb from "exploding". If the bomb does explode, the fuse sound is terminated and a loud "boom" sound is produced which decays slowly and simulates the explosion of a bomb.
