In response to the modulation signal, the driving unit generates a driving signal to control operations of the heating unit, so that a temperature difference between the first temperature and the second temperature is maintained constant. A specified relation between the wind speed and the modulation signal facilitates discriminating whether a dust-proof element of the electronic device needs to be replaced. | 08-19-2010 |
20110303002 | "X" WIRED ANEMOMETRIC PROBE AND ITS MANUFACTURING METHOD - A method for manufacturing a single-wire anemometric probe, or an n-wire (n>1) probe, for making measurements near a surface, comprising, for at least one of the wires: a) positioning and holding of a straight portion of the wire, comprising a metal core surrounded by a protective sheath, on two surfaces; b) elimination of a part of the sheath, to expose an active wire measurement zone; and c) the wire is soldered on two pins of the probe body. | 12-15-2011 |
20110308311 | Thermal Anemometer Flow Meter for The Measurement of Wet Gas Flow - A flow body flow meter includes a flow body and a sensor having one or more probes in the flow body. As a wet gas stream enters the flow body, an internal passage imparts angular momentum to the stream to induce a rotating flow. The wet gas stream at least intermittently carries liquid phase particles and the inertia of the denser liquid phase particles separates them from the rotating flow. The probes of the sensor are located in a part of the rotating flow that is free of any liquid phase particles. The internal passage may include an axial swirler and a cylindrical section downstream from the axial swirler. The axial swirler imparts the nonlinear motion to the stream, and tips of the probes are located near a center axis of the cylindrical section so they are free of any liquid phase particles. | 12-22-2011 |

20090049905 | Position Correction in Sodar and Meteorological Lidar Systems - A system and method for correcting wind speed and direction data collected by a sodar or lidar apparatus for the orientation and/or position of the apparatus. There are sensors mounted to the sodar or lidar apparatus that detect the orientation and position of the apparatus. Software is used to adjust in situ the calculations of wind speeds and directions in three dimensions for deviations from some nominal orientation. Software and data structures can be used to cause the inclusion of the orientation and position of the system with the collected data. | 02-26-2009 |

20100186497 | Aerodynamic Measurement Probe of an Airstream Along a Wall - The invention relates to an aerodynamic measurement probe of an airstream along a wall. The invention makes it possible notably to determine the attack of an airstream relative to an axial reference tangential to the wall. The invention is particularly useful in the aeronautical field. According to the invention, the probe comprises several emitters that can each emit a sound wave and a receiver sensitive to the different sound waves. Thus, there is forewarning of the receiver error that is common to all the measurements of travel time of a sound wave between one of the emitters and the receiver. | 07-29-2010 |

A signal processor determines a geometric mean coherence based on the detected low frequency sounds. A display displays wake vortices based on the determined geometric mean coherence. | 11-05-2015 |
20160161525 | APPARATUS AND A METHOD FOR PROVIDING A TIME MEASUREMENT - Apparatus for measuring the time taken for sound to travel a predetermined distance, including a transmitter electroacoustic transducer for transmitting an acoustic signal, and a receiver electroacoustic transducer, spaced from the transmitter electroacoustic transducer, for receiving the transmitted acoustic signal. The apparatus has a sound reflective surface spaced from the receiver electroacoustic transducer, so the latter also receives a reflection of the acoustic signal, and timing electrical circuitry connected to the receiver electroacoustic transducer to provide a measure of the time delay between the respective receptions by the receiver electroacoustic transducer of the acoustic signal and its reflection. The invention extends to a flowmeter ( | 06-09-2016 |
