Therefore a quest for a new concept was launched. This new design incorporates a manual or automatic remote initiation of the measurement. The system can be coupled to the MacFinish system, to a large scoreboard or to a personal computer. This brace houses two transducers. A transducer is both a microphone and loudspeaker for ultrasound incorporated in one case.
Sound bursts travel between the arms of the structure.
The box is mounted on a height-adjustable pole. On the Windspeed unit itself, measuring commands can be given and results can be read. The commands and reading can also be performed by the MacFinish unit using a simple cable to connect the devices. This eliminates the need for an official to verify the wind speed on each race. An extra connection can be made in order to display the results of the wind reading on a medium size or large size scoreboard.
