Anemometer beam exits reflect, or backscatter, the light back into a detector, where it is measured relative to the original laser beam. When the particles are in great motion, they produce a Doppler shift for measuring wind speed in the laser light, which is used to calculate the speed of the particles, and therefore the air around the anemometer. Ultrasonic anemometers, first developed in the 1950s, use ultrasonic sound waves to measure wind velocity. They measure wind speed based on the time of flight of sonic pulses between pairs of transducers. Measurements from pairs of transducers can be combined to yield
Measure B a building making decisions for the whole industry. They don't even make decisions on the moratoriums; a doctor does, and she had no idea about that and what the testing protocols—how the doctors work with them to make the most safe tests available; she had no idea. In the thirty-five minute meeting Director Hutt mentioned that in the 2012 election the most votes cast in any district in favor of passage of Measure B came from Hall's district. Actress Nina Hartley countered that although Measure B and AB 1576 were written by policy makers at AIDS Healthcare Foundation, the AHF
