摘要： A sensor includes a heater, a thermal insulator between two thermometer layers, the heater generating a thermal gradient within the thermal insulator. The thermometers give an indirect measurement of fluid flow around the sensor, based on their temperature readings. The thermometers are flexible layers including gels.

摘要： A flow measurement device includes a flow sensor that senses a flow rate of a measurement target fluid flowing through a main channel, a characteristic-value obtaining unit that includes a heater heating the target fluid and a temperature sensor sensing a temperature of the target fluid, and obtains a characteristic value of the target fluid, and a flow rate correction unit that corrects a flow rate of the target fluid calculated based on a sensing signal from the flow sensor using the characteristic value of the target fluid obtained by the characteristic-value obtaining unit. The heater and the temperature sensor are arranged parallel to each other in a direction orthogonal to a flow direction of the target fluid. The characteristic-value obtaining unit obtains the characteristic value based on a difference between the temperatures of the target fluid sensed by the temperature sensor before and after the heater temperature is changed.

摘要： Systems, methods, and computer program products for identifying hostile fire. A characteristic of a fired projectile is detected using an optical system and the projectile's travel path in relation to a vehicle is determined. If the determined travel path of the projectile is within a predetermined distance from the vehicle, it is determined that the projectile is hostile towards the vehicle and a warning is output.

摘要： Systems and methods for determining an effective wind speed are disclosed. A system includes a first detector, a second detector and a processing unit. The first detector includes a heated temperature-sensing element having a heater and a first temperature sensor, and a first housing at least partially housing the heated temperature-sensing element. The second detector includes a non-heated temperature-sensing element having a second temperature sensor, a second housing at least partially housing the non-heated temperature-sensing element. The processing unit can be adapted to determine the effective wind speed according to a temperature at the heated temperature-sensing element, a temperature at the non-heated temperature-sensing element, and/or a difference between these temperatures and in accordance with an algorithm or table of values. The heated and non-heated temperature-sensing elements and their respective first housing and second housing are collinear, proximal and parallel to the conductor, and protected from precipitation by a shield.

摘要： Embodiments relate to a system and vehicle for controlling the flight of a vehicle without the need to use pressure sensors. The system includes a plurality of pairwise thermal air data (TAD) sensors being controlled to have a constant temperature during heat dissipation into the atmosphere by each sensor. The system includes at least one processor configured to measure power for maintaining the constant temperature to calculate an angle of attack, a sideslip and a free stream vehicle velocity at infinity to control flight of a vehicle.

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.

摘要： An apparatus, control system and methods are disclosed for directly measuring a blood pressure gradient, i.e. by real-time pressure measurements, with particular application for in situ measurement of transvalvular blood pressure gradients for the aortic valve and other heart valves, using minimally-invasive techniques. The apparatus takes the form of a multi-sensor assembly, enclosed within a micro-catheter or a steerable guidewire, and comprises a plurality of optical pressure sensors arranged along a length of the distal end portion, for measuring pressure simultaneously at each sensor location. For example, four MOMS optical pressure sensors, and optionally, a temperature and/or flow sensor, are incorporated into a distal end portion having a diameter of 0.89 mm or less, and preferably 0.46 mm or less. Beneficially, all sensors are optically coupled, via respective optical fibers, to an optical coupler at the proximal end of the multi-sensor apparatus, without requiring electrical connections.
