A method for evaluating a turbine component (14) includes inducing a thermal response of the component (14) at an initial time, capturing a two-dimensional infrared image (59) of the thermal response of the component (14) with a thermal imaging device (10), wherein the two-dimensional infrared image (59) comprises a plurality of infrared image pixels (P), generating a two-dimension to three-dimension mapping template to correlate two-dimensional infrared image data with three-dimensional locations on the component (14), mapping at least a subset of the plurality of infrared image pixels (P) of the two-dimensional infrared image (59) to three-dimensional coordinates using the mapping template, and generating a three-dimensional infrared image (62) and infrared data of the component (14) from the mapped infrared image pixels (P) to three-dimensional coordinates, wherein the three-dimensional infrared image (62) and infrared data is used to qualify the component (14) for use.

La présente invention se rapporte à une méthode pour déterminer, en temps réel, la consommation énergétique d'une chaudière (1) à partir du signal électrique de commande (4) transmis par le régulateur au brûleur.

Selon l'invention, cette méthode est caractérisée en ce que :

a) durant un intervalle de temps comprenant une pluralité d'instants t, on réceptionne ledit signal électrique de commande, acquis sans perturbation significative du signal originel, et on le conditionne électriquement en vue d'une interprétation par une unité de calcul,

b) on transmet ce signal électriquement conditionné à une unité (6) de calcul qui lui applique, ainsi qu'aux valeurs des paramètres qui sont fonction des caractéristiques dudit brûleur, une transformation mathématique qui convertit ce signal de commande et ces valeurs des paramètres en consommation de combustible, ce qui permet de déterminer la consommation de combustible à chaque instant t,

c) on intègre alors, en fonction du temps, cette consommation de combustible à chaque instant t, ce qui permet de déterminer la consommation énergétique durant ledit intervalle de temps.

L'invention concerne également un dispositif pour la mise en oeuvre de cette méthode.

An arterial needle removes blood from the access to an extracorporeal circuit comprising a dialyzer and a venous needle returns the blood to the access site. Blood passes along one side of the membrane of the dialyzer and dialysis fluid along the other side. Fistula or access recirculation is detected by changing the blood flow rate, monitoring the concentration of a substance in the dialysate emitted from the dialyzer and correlating a change in the concentration to the change of the blood flow rate.

A fuel delivery system for an internal combustion engine is disclosed which has an injector for delivering diesel fuel, and a fuel delivery system for delivering liquid petroleum gas fuel. The fuels are delivered concurrently to the engine. A first transducer measures the amount of diesel fuel supplied to the engine by the injector, and a second flow transducer measures the amount of diesel fuel returned from the injector. A measuring unit determines the amount of fuel delivered by the injector to the engine by subtracting the amount as measured by the second flow meter from the amount measured by the first flow meter. Thus, the instantaneous flow rate of the diesel fuel can be determined and therefore, the amount of LPG which should be delivered in order to control emissions from the engine and to set the right ratio of the diesel fuel to the LPG fuel can also be determined.

Die Erfindung betrifft ein Verfahren zur Steuerung und/oder Diagnose eines Kraftstoffzumeßsystems einer Brennkraftmaschine, wobei die Brennkraftmaschine eine Gemischadaptionsfunktion aufweist und wobei Kraftstoff von wenigstens einem Ventil direkt in wenigstens einen Brennraum eingespritzt wird. Die Erfindung betrifft weiterhin ein entsprechendes Computerprogramm für eine Brennkraftmaschine eines Kraftfahrzeugs, ein Steuergerät zur Steuerung und/oder Diagnose eines Kraftstoffzumeßsystems einer Brennkraftmaschine sowie eine Brennkraftmaschine mit wenigstens einem Steuergerät zur Steuerung und/oder Diagnose eines Kraftstoffzumeßsystems der Brennkraftmaschine.

Fuel consumption of an internal combustion engine provided with fuel injection is monitored by means of a flow sensor 20 included in the fuel supply line 11 between tank 18 and fuel pump 10. The fuel return 14 from injector distributor 12 and/or injectors 13 is re-routed from the conventional path to the fuel tank 18 and instead joins the supply line 11 by means of a T-piece 15 between sensor 20 and pump 10. A radiator 30 is included in the fuel return line 14 for cooling recirculating fuel thereby preventing fuel vapour lock.

A fuel flow measuring system includes a return fuel storage tank (11) mounted inside a main storage tank (10), a float (16) sensitive to the fuel level in the return fuel tank and, a valve 17 or other means operated by the float (16) and varying the ratio of the quantity of fuel drawn from the main tank to the quantity of fuel drawn from the return tank so as to maintain the level of fuel in the return tank constant. A fuel flow measuring device (17) is connected to measure only the quantity of fuel drawn from the main tank (10).
