  • Patent number: 5405149
    Abstract: A paddle, including a surface for hitting a ball or other object, a transducer coupled to the hitting surface for detecting when the hitting surface hits the object, a counter for counting the number of hits and a display is disclosed. In one arrangement, the counter is a processor from a microcontroller. A timer is coupled to the transducer and to the counter for determining the time elapsed from the last hit. The timer stops the counter when the time elapsed since the most recent hit exceeds a predetermined length of time, indicating a miss of the ball. An audio amplifier drives a speaker so that the speaker makes a first predetermined sound whenever the hitting surface hits the object. The speaker emits a second predetermined sound when there is a miss, as indicated by the timer. A manual reset is coupled to the processor. A push button resets the counter to zero. A source of electric power, such as batteries, is located inside the handle.
