Abstract

A basketball game device includes a backboard to which a mount is attached for supporting a rim loop ring. A detector is mounted to an underside of the mount and transmits ultrasonic waves to a work space below the rim loop ring. The work space has an outer bound beyond distance of a remote edge of the rim loop ring. A valid distance within the remote edge of the rim loop ring is set in the detector. The detector repeatedly generates ultrasonic waves toward an object and detects the reflected signals representing a series of data corresponding to distances of the object. If the first data of the series of data indicates a distance shorter than the valid distance, the goal is considered legal and if the first data is a distance greater than the valid distance, the goal is illegal.

Claims

1. A method for detection legal goal in a basketball game device comprising a rim loop ring, the method comprising the following steps:

(1) providing an ultrasonic detector, which generates ultrasonic waves and received reflected signals of the ultrasonic waves, in a downward inclined manner whereby the ultrasonic waves are transmitted in a work space below the rim loop ring, the work space having an outer bound beyond distance of a remote edge of the rim loop ring;

(2) setting a valid distance within the remote edge of the rim loop ring;

(3) repeatedly generating ultrasonic waves toward an object and detecting the reflected signals representing a series of data corresponding to distances of the object; and

(4) determining a legal goal by processing the series of data.

2. The method as claimed in claim 1, wherein the basketball game device comprises a backboard to which a mount is attached for supporting the rim loop ring, the detector being attached to an underside of the mount.

3. The method as claimed in claim 1, wherein the valid distance that is shorter than the remote edge of the rim loop ring is greater that distance of a center point of the rim loop ring.

4. A basketball game device comprising:

a backboard;

a rim loop ring attached to a front side of the backboard;

a detector arranged on a rear side of the rim loop ring and inclined downward to project ultrasonic wave toward a work space below the rim loop ring, the work space having an outer bound defining a reaction distance extending beyond a remote edge of the rim loop ring, a valid distance being shorter than the remote edge of the rim loop ring, the detector being adapted to transmit ultrasonic waves to an object and receive reflected signals representing a series of data corresponding to distances of the object which are processed by the detector to determine a legal goal.

5. The basketball game device as claimed in claim 4, wherein the ultrasonic detector is mounted to a mount that fixes the rim loop ring to the backboard.

6. The basketball game device as claimed in claim 4, wherein the valid distance that is shorter than the distance of the remote edge of the rim loop ring is greater than a distance of a center point of the rim loop ring.
