Latest Patents

Fujita holds a patent for a "Method and apparatus for measuring gas flow speed." This invention is particularly suitable for detecting wind speed. The method utilizes the gas flow to create a negative pressure across a pressure sampling port, which is oriented with its axis substantially perpendicular to the gas flow. The negative pressure is generated by accelerating the gas flow streamlines over a surface of revolution containing the port. The negative pressure is then compared with a reference pressure using a pressure transducer, which provides an output representative of the gas speed. In its preferred form, the apparatus includes a first pressure probe shaped like a sphere, mounted on a tube projecting axially from a hollow cylindrical cup-like member. The sampling port is located in the base of the sphere, while the cup-like member serves as a second pressure probe, with a pressure tapping internally providing the source of reference pressure.
