Abstract: Described is a device for measuring wind conditions during power kite activities. The device comprises an electronic processing unit, an anemometer, and a means of attachment to a power kite. The data from the anemometer is processed by the processing unit and stored locally or transmitted wirelessly to a secondary device (e.g. a smart phone or smart watch). The anemometer directly measures the apparent wind at the kite. In certain embodiments inclusion of an inertial measurement unit and a GPS unit provides a means of calculating the true wind by accounting for induced wind from kite and kiter motion respectively.

Abstract: A biohazard centrifuge having an improved air cooling arrangement, wherein a cooling air stream is directed onto and around the rotor chamber of the centrifuge without introducing cooling air thereinto. This results in cooling air being separated from the spinning rotor and reduces the possibility of contamination of the cooling air stream from a leaking sample container. Additionally, further protection to laboratory personnel is afforded by a sealed rotor assembly chamber, and by providing rotor assembly specimen containers or carriers having lids which are easily attached and removed, requiring a simple partial twist to lock the lids into place.
