Anemometer turbines usually requires a refresh rate of wind speed measurements of 3 Hz, easily achieved by sonic anemometers. Three-dimensional sonic anemometers are widely used to measure gas emissions and ecosystem fluxes using the eddy covariance method when used with fast-response infrared gas analyzers or laser-based analyzers. Two-dimensional wind sensors are of two types: Acoustic resonance anemometers are a more recent variant of sonic anemometer. The technology was invented by Dr Savvas Kapartis and patented in 2000. Whereas conventional sonic anemometers rely on time of flight measurement, acoustic resonance sensors use resonating acoustic (ultrasonic) waves within a small purpose-built cavity in
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
