Description
Technical Field
The present invention relates to a signal receiving apparatus; the invention also relates to a ball positioning and scoring system.
Background
Players are required to exercise to improve their proficiency because they try to hit the ball to a desired target area in some sports, such as golf. Conventional methods of operation require an observer to determine how close the ball is to the target area and record the score. This method is both inaccurate and time consuming, particularly when a training field has a large number of players training together and a target area has a large number of balls.
Although some systems utilize radio frequency identification technology (U.S. Pat. No.: US9339697B2, by Luciano, Jr. et al), in this case, the scores can be tracked using RFID chip balls. However, this solution requires extensive modifications of the training and target areas, such as the insertion of funnel-like structures therein, in order to guide each ball falling into a designated area to the RFID reader, since the read range of these passive RFID readers is small. However, such a reconstruction involves a land excavation work, causes the natural environment to be destroyed, and is expensive.
In view of the problems with the existing systems, there is a need for improvements to the existing related devices and systems.
