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
What Kate Does that it by no means compared to "LA X", but stated that it "contain[ed] scenes of incredible beauty, based on character work and stakes earned over five seasons [that] made it a fine, if imperfect, hour." McGee also commented that the scene in which Claire arrives at the hospital and is helped by Ethan as "freakin' outstanding" and called "What Kate Does" "one of the funniest in the show's history. Aldo, Hurley, and Miles all got off plenty of zingers, which will be necessary in a season in which both mythological and dramatic stakes are raising higher and higher each
