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.
Description
- 1. Field of the Invention
- The present invention relates generally to a basketball game device, and in particular to detection of legal goal in the basketball game device by means of ultrasonic detection technique.
- 2. The Related Art
- Basketball game devices are known and commonly used for convenience and ease to install. The basketball game devices are commonly installed in for example garages and backyards. An example of the basketball game device is shown in FIG. 1 of the attached drawings, comprising a
backboard 11 to which arim hoop ring 12 is mounted by amount 14. A net 13 is attached to therim hoop ring 12. Conventionally, a score-counting device is incorporated to count the scores or number of goals. Such a score-counting device generally comprises photo-electrical means or mechanical means for determining legal goal. However, such devices are not capable to exclude illegal goals, that is balls moving through a rim loop ring in an upward direction from below the net. - U.S. Pat. No. 6,389,368 teaches using two photo-electrical sensors spaced in a vertical direction to eliminate incorrect count of illegal goals in “reversed” direction. However, counting score based on photo-electrical sensors may be affected by surrounding light, giving incorrect counting result. Thus, basketball game devices with photo-electrical sensor are subject to limitation of installation site and can only be installed in locations, especially indoors, where surrounding light is not intense enough to affect the counting result.
- An object of the present invention is to provide a basketball game device that can be installed in a light intense environment, such as outdoors, by employing ultrasonic technique to detect legal goals.
- In accordance with an aspect of the present invention, a basketball game device comprises an ultrasonic detector comprising a transmitter and a receiver that transmits ultrasonic waves to a moving object and receives the reflected signals, respectively. Distances of the moving object are calculated based on the time elapses between the transmission of ultrasonic waves and the detection of the reflected signals. The detector is arranged to transmit ultrasonic waves in a work space below a rim loop ring of the basketball game device. A valid distance that is shorter than distance of the remote edge of the rim loop ring is set in the detector. A legal goal is determined if a first distance of the moving object is detected within the valid distance.
- Thus, a detector comprising a single transmitter and a single receiver is capable to detect and determine a legal goal and the detection is not affected by surrounding light.
- The present invention will be apparent to those skilled in the art by reading the following description of the best mode and a preferred embodiment thereof, with reference to the attached drawings, in which:
- FIG. 1 is a perspective view of a basketball game device;
- FIG. 2 is a schematic view showing the principle of ultrasonic detection;
- FIG. 3a is a side elevational view of a basketball game device incorporating an ultrasonic detection device of the present invention; and
- FIG. 3b is a top plan view of FIG. 3a.
- With reference to the drawings and in particular to FIG. 2, an ultrasonic detection device generally designated with
reference numeral 20, comprises an ultrasonic wavesignal generating device 21 and an ultrasonicwave receiving device 22. The ultrasonic wavesignal generating device 21, serving as a transmitter, generates and transmits an ultrasonic wave. The wave that impacts anobject 23, such as a basketball in the example of the basketball game device, is reflected by theobject 23 and thereafter detected and received by the ultrasonic wavesignal receiving device 22 that serves as a receiver. Based on the time elapse between the transmission and receipt of the ultrasonic wave signal, the distance of theobject 23 from a given reference datum can be calculated. The ultrasonic detection device is subject to limitation in detection distance and angle and a work space for the ultrasonic detection device, which is sector-shaped, is indicated by reference character A in the drawings. In other words, theobject 23 can be correctly detected when theobject 23 is within the work space A of theultrasonic detection device 20. - Also referring to FIGS. 3a and 3 b, according to the present invention, in a basketball game device comprising a
backboard 31 having a front side to which amount 34 is attached for supporting arim loop ring 32. Adetector 33 comprising thedetection device 20 is mounted to an underside of themount 34 and arranged in a downward inclined orientation. Thus, thedetector 33 is arranged at rear side of therim loop ring 32 and the ultrasonic wave generated by thedetector 33 is transmitted in a work space A under therim loop ring 32. Therefore, thedetector 33 makes no detection to objects above thering 32. Thedetector 33 performs detection within a distance, referred to as reaction distance indicated by reference character N, representing an outer bound of the work space A that is beyond thering 32. Also, a valid distance, indicated by reference numeral V, is set in thedetector 33 which is within therim loop ring 32 or shorter than the distance of a remote side of therim loop ring 32, as viewed from the top side of therim loop ring 32 illustrated in FIG. 3b. Preferably, the valid distance V is greater than the distance of a center point of therim loop ring 32. Thedetector 33 repeatedly transmits ultrasonic waves to detect distances of a moving ball and the distances of the ball are processed to determine if it is a legal goal. - A legal goal must travel into the
rim loop ring 32 from above therim loop ring 32. Thus, the distance of the ball at the first time the ball is detected by thedetector 33 is within the valid distance V. In other words, in a series of detected data of distances of the ball, if the first data is within the range set by the valid distance V, the goal is considered legal. - Since the valid distance V is shorter than the reaction distance N, when a ball travels into the
rim loop ring 32 from below therim loop ring 32, the first time the ball is detected is at a location between the reaction distance N and the valid distance V and thereafter the ball is detected at a location within the range of the valid distance V. Thus, in a series of distance data detected by thedetector 33, if the first data is beyond the valid distance V, then the goal is considered illegal and thus not counted. - In case a net is attached to the
rim loop ring 32, the net is configured to forming an opening at the side adjacent themount 34 for not interfering with the operation of thedetector 33. Such an opening is small enough to not interfere with the basketball game, but large enough to allow transmission of ultrasonic waves. The ultrasonic waves are reflected by the opposite, remote side of the net, and then received by thedetector 33. Since the valid distance V is shorter than the farthest distance of therim loop ring 32, which substantially corresponding to the distance of the remote side of therim loop ring 32, the signals reflected by the remote side of the net constitute no valid signal and thus do not interfere with the operation of thedetector 33. - However, for a legal goal, the ball travels into the
rim loop ring 32 from above therim loop ring 32. The distance of the ball is first detected within the valid distance V. However, since the remote side of the net is detected before the first detection of the ball approaching therim loop ring 32. Thus, a foul determination of illegal goal may be made due to the preceding detected signals of the remote side of the net. To overcome the deficiency, repeatedly detected signals of an object at a constant distance or signals representing an object at different distances with a small distance change therebetween are neglected. By neglecting these “noise” signals, a legal goal can be correctly determined. - Thus, in a series of distance data representing the distance of an object detected by the
detector 33, successful data of constant distance or more practically, data with small change therebetween are neglected first. The remaining data are processed and a legal goal is determined if the first data is beyond the valid distance V. - To this point, it is apparent that a single set of transmitter and receiver is sufficient to determine if a goal is legal and correct score can be calculated in accordance therewith. The operation of the goal detection is not affected by intense surrounding light and is more durable as compared to the mechanical type detector. Thus, advantages over the prior art are obvious to those having ordinary skills.
- Although the present invention has been described with reference to the best mode and a preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
