摘要： A method for measuring a windspeed vector is described. A true airspeed vector of a flying machine is measured while the machine is in flight using one or more nanowires on the flying machine. Each nanowire is configured to measure a value of local air velocity relative to the flying machine. A velocity of the flying machine relative to the ground is measured while the machine is in flight, and then (a) the true airspeed vector is subtracted from (b) the velocity of the flying machine relative to the ground. Other applications are also described.

摘要： A two-dimensional wind-speed and wind-direction sensor and a system thereof are provided, relating to the field of sensing devices, in order to alleviate the problem that the prior art fails to meet the user's demand for measuring two-dimensional wind speed and wind direction, and thus results in poor user experience, and to improve the user experience. The two-dimensional wind-speed and wind-direction sensor includes: an X-direction wind speed probe assembly and a Y-direction wind speed probe assembly, the X-direction wind speed probe assembly and the Y-direction wind speed probe assembly are perpendicular to each other, and the X-direction wind speed probe assembly is configured to measure a X-direction wind speed including a wind speed in the reverse direction of an X-axis, Vx−, and a wind speed in the forward direction of the X-axis Vx+; and the Y-direction wind speed probe assembly is configured to measure a Y-direction wind speed including a wind speed in reverse direction of an Y-axis, Vy−, and a wind speed in the forward direction of the Y-axis, Vy+. In addition, the sensor has a simple structure and a small volume, and is convenient to be installed; and has a high sensitivity, enabling a high-precision measurement of a low wind speed, thereby ensuring accuracy of the measurement of two-dimensional wind speed and wind direction; and also has the advantages of safety and reliability.

摘要： An electronic device for detecting an air flow includes at least one sensor having a pair of platelets, each platelet having an RTD and having one end fixed, the other end being free and overlapping the free end of the other platelet. A platelet is flexible so as to form a switch for an electrical circuit. An air flow with a speed higher than a predetermined speed makes the sensor go from a first state, corresponding to a closed switch, in which the free ends of the platelets are in contact, to a second state, corresponding to an open switch, in which said contact is broken. A detection module allows, for each sensor, a resistance of the electrical circuit to be measured, the resistance corresponding to the RTDs being connected in parallel when the switch is closed or to one of the RTDs when the switch is open.

摘要： A mass flowmeter includes a flow sensor having a first sensor part and a second sensor part formed on both sides of a heater part. The flow sensor is formed of a thermoplastic resin, and is configured of a multi-layer substrate including a plurality of stacked insulating layers, and a first conductor and a second conductor and formed on these insulating layers and connected to each other. The multi-layer substrate is formed by pressurizing and heating the plurality of insulating layers for integration. When a fluid having heat released from the heater part is moved along the one face of the flow sensor, the first and the second sensor parts and generate electromotive forces in the level corresponding to temperature differences generated between the one face and the other face in the first and the second sensor parts. The flow sensor has a structure manufactured by pressurizing and heating the plurality of insulating layers for integration. The structure has no large space unlike a structure having a space immediately below a diaphragm. Thus, the flow sensor is less breakable than a sensor having a diaphragm structure is.
