摘要： Apparatus (100) is provided comprising an optical micro-sensor (10) for directly measuring a fluid temperature and flow by thermoconvection, which suitable for medical applications, e.g. using minimally-invasive cardiovascular techniques. A multi-sensor apparatus (100) may take the form of a micro-catheter or steerable guidewire, equipped with a plurality of miniaturized optical sensors (10) arranged along a length of the distal end (101), each coupled via optical fibers (11) to a proximal end (102) comprising an input/output connector (112) to the control system (110), without the need for electrical connections. This enables direct measurement of blood flow, temperature and/or blood pressure simultaneously at several locations within the blood vessels or the heart, including transvalvular measurements. Preferably, the distal end portion has a diameter of 0.89 mm (0.035″) or less, and more preferably 0.46 mm (0.018″) or less, so that there is negligible effect on valve movement, transvalvular pressure gradient and flow during measurement.

摘要： A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a time-varying speed estimate from their time-varying temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Various methods are given to determine the azimuth and range of a projectile, both for clear atmospheric conditions and for nonhomogeneous atmospheric conditions. One approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. A second uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.

摘要： A thermal flow sensor integrated circuit for sensing flow in a channel based on temperature measurements, the integrated circuit having a temperature sensing element (30) on a front side of the integrated circuit arranged to face the channel, and a bond pad (60, 200) coupled electrically to the temperature sensing element, for making electrical contact off the integrated circuit, the bond pad being arranged to face away from the channel. By having the bond pad facing away from the channel, the space needed for the bond pad and any connections to it need not extend beyond the temperature sensing element and get in the way of the channel. Hence the temperature sensing element can be located closer to the channel or in the channel to enable measurements with better response time and sensitivity.

摘要： A wind speed detecting circuit includes a heating unit, a first temperature sensor, a second temperature sensor, a control unit and a driving unit. The first temperature sensor detects a first temperature of an internal portion of an electronic device, thereby generating a first detecting signal. The second temperature sensor detects a second temperature of the heating unit, thereby generating a second detecting signal. The control unit generates a modulation signal according to the first detecting signal and the second detecting signal. 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.

The measuring element has fiber-optic cable and at least two electrical heating elements that lie adjacent to the fiber-optic cable(s) by which a respective heat stream emanating from the respective heating element and directed towards the fiber-optic cable, the directions of the heat streams being at least proportionately reversed.

Additionally, the flowmeter has a control unit, which is used to feed electric energy to the two or more heating elements, one after the other, and an evaluation unit, which is used to evaluate the temperature effect of the electromagnetic wave emanating from the individual heat streams and to determine the flow direction of the fluid.
