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
Does exactly what it says on the tin began a similar copycat advertising campaign in Ireland stating that its product "does exactly what it says on the tube". The phrase is a registered trademark of the Sherwin-Williams Company, the owner of Ronseal, across the European Community for products including paints, varnishes, and wood preservatives (E3085826). In 2007, a song titled "What It Says on the Tin" was released by the British singer Katie Melua. Although the song is about relationships, the phrase has a similar meaning. Does exactly what it says on the tin "It does exactly what it says on the tin" was originally an advertising slogan
