Goal detector for detection of an object passing a goal plane
First Claim
1. A system comprising:
- a movable object,a plurality of pairs of antennas arranged with a goal including two goal posts and a horizontal crossbar that delimit a periphery of a flat target plane, one antenna of each of said pairs being arranged and displaced from the other antenna of each of said pairs in a direction perpendicular to the flat target plane,radio wave emitter means arranged in the movable object and/or each antenna, andmeans for receiving radio waves from the radio wave emitter means and for providing an output accordingly arranged in each antenna and/or in the movable object,at least one stationary auto-calibration transmitter arranged in the flat target plane and configured to provide a calibration signal to the plurality of pairs of antennas, andprocessing means to receive and process said output together with a predetermined set of conditions and to provide a resulting output if the set of conditions are fulfilled so as to determine whether the movable object passes the flat target plane.

Abstract
A system is disclosed for detection of whether a movable object, such as a sports object, e.g. a football or an ice hockey puck, has passed a flat plane in space, such as a goal plane defined e.g. as a vertical plane extending from a goal line or a horizontal plane defined by the upper rim of the basketball basket. The system comprises a plurality of pairs of antennas arranged along the periphery of the flat target plane, the two antennas of each of said pairs being arranged with a mutual displacement in the direction perpendicularly to the flat target plane, radio wave emitter means arranged in the movable object and/or each antenna, and means for receiving the radio waves from the radio wave emitter means and provide an output accordingly arranged in each antenna and/or in the movable object, the system further comprising processing means to receive and process said output together with a predetermined set of conditions and providing a resulting output if the set of conditions are fulfilled so as to determine whether the movable object passes the flat target plane.

16. A system comprising:
-
a movable object, a plurality of pairs of antennas arranged with a goal including two goal posts and a horizontal crossbar that delimit a periphery of a flat target plane, both antennas of each of said pairs being arranged and displaced at a discernable depth from said flat target plane, radio wave emitter means arranged in the movable object and/or each antenna, and means for receiving radio waves from the radio wave emitter means and for providing an output accordingly arranged in each antenna and/or in the movable object, at least one stationary auto-calibration transmitter arranged in the flat target plane and configured to provide a calibration signal to the plurality of pairs of antennas, and processing means to receive and process said output together with a predetermined set of conditions and to provide a resulting output if the set of conditions are fulfilled so as to determine whether the movable object passes the flat target plane. - View Dependent Claims (17)
