| 20090025468 | Piezoelectric Combustion Chamber Pressure Sensor Having a Pressure Transmission Pin - A sensor made of a single-crystal, piezoelectric material for measuring the pressure in a combustion chamber of an internal combustion engine, having a pressure transmission pin, a displaceably mounted heating pin protruding into the combustion chamber being provided as the pressure transmission pin, and the sensor being friction-locked with the heating pin. The sensor is preferably situated between the heating pin and a rigid thrust bearing. The single-crystal piezoelectric material of the sensor is preferably made of lithium niobate (LiNbO | 01-29-2009 |
| 20090222231 | Method and device for correcting a signal of a sensor - A method and a device for correcting a signal of a sensor provide for maximally accurate drift compensation of a characteristics curve of the sensor. At least one characteristic quantity of the signal of the sensor is compared with a reference value. The signal of the sensor is corrected as a function of the comparison result. A value of the at least one characteristic quantity of the signal of the sensor derived from the signal of the sensor is formed as the reference value. | 09-03-2009 |
| 20100060260 | MEASUREMENT SENSOR, METHOD FOR ANALYZING A NONPOLAR LIQUID, METHOD FOR MANUFACTURING A MEASUREMENT SENSOR - A measurement sensor for analyzing a nonpolar liquid contains a field effect transistor that has an exposed gate contact for wetting with the nonpolar liquid, and an electrical shield that surrounds the gate contact and has openings for inflow and outflow of the nonpolar liquid. | 03-11-2010 |
| 20110315115 | Method for operating an internal combustion engine - A method for operating an internal combustion engine is described. At least one composition of a gas mixture is determined in at least one combustion chamber of the internal combustion engine. At least one combustion chamber pressure is detected in the interior of the combustion chamber and at least one local combustion chamber temperature is detected in the interior of the combustion chamber. The composition is inferred from the combustion chamber pressure and the combustion chamber temperature. | 12-29-2011 |

| 20100287730 | RUNNER PIN FOR A ROLLER - The invention relates to a caster, in particular furniture caster, having a housing which is rotatably fastened, by means of a caster stem arranged vertically in an opening of the housing, to an object to be supported by the caster, wherein the caster stem has a first section which is arranged in the opening of the housing and a second section which projects beyond the housing. To create, in a simple and cost-effective manner, a caster stem which permanently prevents an undesired generation of noise as a result of relative movements between the caster stem and the object to be supported, it is proposed according to the invention that at least two annular grooves are provided in that section of the caster stem which projects beyond the housing, in which annular grooves in each case one elastic retaining ring is arranged without play. | 11-18-2010 |
| 20100299869 | WHEEL FOR FURNITURE ROLLER WITH LOCKING DEVICE - The invention relates to a wheel for a furniture roller having a locking device, having a rigid wheel core with a hub for holding an axle and having an elastic wheel casing as a running surface. According to the invention, in order to be able to realize a locking device which is effective even for small wheel diameters, an inwardly pointing toothing is provided on an outer ring of the wheel core, wherein at least one aperture is formed in the outer ring between the tooth flanks, into which aperture a web, which is aligned axially in parallel and which is offset radially inward with respect to the running surface, of the wheel casing engages in a positively locking manner. | 12-02-2010 |
