System - Offside signaling
The problem the inventor(s) wanted to solve
invention allows unambiguous judgment of touch lines, goal lines, off side
positions and goals.
or more cameras record the event on the field, the data of which are analyzed
by a software programme, and the result is immediately forwarded through a
radio transmitter-receiver to the assistant referee who is to judge the event,
with the help of the special rod of the flag.
the whole of the ball has been passed out of the field, the rod of the flag,
triggered by a small engine inside, signals for the assistant referee with a
shaking movement and a buzzing sound for three seconds. At the same time, the
red lamp on the rod comes on. When the whole of the ball has been passed
beyond the goal line, the green light comes on, together with the shaking
movement and the buzzing sound. If the software program identifies an off side
position at the moment when the ball is kicked, it transmits a radio signal
towards the flag rod. If the assistant referee pushes the button, he will
experience the shaking-buzzing signal. In this case, the yellow light comes on
for three seconds. The assistant does not need to be in line with the players:
the signal is sent regardless his position. A flashing blue light on the flag
rod indicates that there is connection with the transmitter, and the system
is in working order.
