  • Publication number: 20140206480
    Abstract: An electronic home plate providing assistance to an umpire in determination whether a pitch results in a “strike” or a “ball”. The electronic home plate is implemented with eye-safe LEDs producing light beams extending vertically. If a ball intersects the light beams, the light reflected from the ball is scattered and incident on photodetectors embedded in the home plate. A microcomputer embedded in the electronic home plate calculates the height of the ball crossing the light beams, and if the height falls between the top and bottom boundaries of a strike zone adjusted to the height of the batter, an indication system is activated to produce a “strike” signal. The microcomputer in the electronic home plate is further configured to calculate speed of the ball passing over the home plate, and the lateral position of the ball.

    Abstract: A sensing device obtains range-related data—such as Doppler data or pulse time-of-flight data—from a sports projectile during flight. The time course of the range-related data is employed, in light of predictable characteristics of the projectile trajectory, to determine and output an accurate determination of the projectile speed for one or more points of interest in its flight. Such determination of speed may, for instance, be the speed at the time of projectile release, even though range-related data is gathered later in the flight, when the projectile is traveling neither so fast, nor straight at the sensor. Such sensing device may employ inexpensive short-range acoustic Doppler, and be incorporated into a target device that automatically displays to a pitcher-in-training the speed and ball/strike condition of each pitch.

    Abstract: The batter monitoring system is a modified home plate for baseball including a sensor unit to detect whether or not the bat crosses the plate as a hitter swings at a pitched ball and also when a runner crosses the plate. After the pitch, a green light is illuminated to indicate that the batter swung the bat or a red light is illuminated if the batter did not swing the bat. Each player would wear a transmitter which the sensor would detect as it crossed the plate, illuminating the lights and sounding a buzzer to indicate when the device is detected crossing the plate. This allows the umpire to watch the ball coming into the baseman's glove and determine whether the ball arrived before or after he heard the buzzer. The sensor, lights, control unit, and buzzer would be built into the plate, and the plate would be recessed into the ground so that its appearance does not differ from that of a conventional home plate.
