WIND DIRECTION RECORDING SYSTEM

摘要

A signal is developed that is proportional to the position of a wind-direction vane. The positions which may be occupied by the vane are divided into a plurality of sectors. Each of the sectors develops a signal when the vane is located in such sector. A time-interval signal also is generated at regular intervals. Each signal is recorded in a separate track of a recording medium such as magnetic tape. From these recorded signals the average wind direction during a time interval may be calculated.
