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 doesn't quite know how to write a woman of action who's also in love … many of the show's Kate flashbacks are just plain silly … there have been a lot of pretty dire Kate episodes." Whitney Matheson of "USA Today" said that she "wanted to stab Kate with a hot poker" after watching "What Kate Does". Josh Holloway's supporting performance as a grieving Sawyer was commended by Carabott of IGN, who said that his acting on the dock as he cried and revealed to Kate that he was going to ask Juliet to marry him was "one of Josh
