<p>The invention comprises a fencing hit detector for wireless scoring systems in the épée and sabre disciplines. The detector is part of the fencer's hit detection unit, does not require a wired connection to the central scoring console and provides output signals that unequivocally determine whether valid hits have been scored. It is compatible with regulation weapons for wired systems, and both fencers can use identical detectors. It comprises: a local ground terminal (1), a local oscillator (2), a constant signal source (3), a signal distributor (4), a differential amplifier (5), a ripple component detector (6), a direct component detector (7), a ground connection terminal (8), an alternating-signal output terminal (9), a signal input terminal (10) and a direct-signal output terminal (11).</p> |
