20090211342 | Method for the Quantitative Determination of an Aging Effect on Motor Oil - The quantitative determination of aging effects on motor oil is of great interest. According to a method, two variables of the motor oil are detected, one of the two variables being the viscosity and the other variable being the acid content of the motor oil. A first deviation of the detected first variable from a default value is then determined, and the second variable is estimated based on the deviation. By determining a second deviation of the estimated second variable from the detected second variable, the second deviation is determined as a measure of the aging effect on the motor oil. Since various aging effects influence the two variables in different manners, individual aging effects may be quantitatively determined in a targeted manner. | 08-27-2009 |

20110110394 | Microstructured sensor for the detection of IR radiation - A microstructured sensor for detecting IR radiation includes: one measuring channel having a measuring diaphragm, on which a first sensitive detector surface is implemented for the absorption of a first IR radiation; and one reference channel having a reference diaphragm, on which a second sensitive detector surface is implemented for the absorption of a second IR radiation. A measuring structure, e.g., a thermopile measuring structure as a series circuit made of thermocouple pairs, is implemented between the measuring diaphragm and the reference diaphragm for measuring a temperature differential between the measuring diaphragm and the reference diaphragm. First and second thermal contacts lie alternately on the two diaphragms. | 05-12-2011 |
20110156726 | MEASURING SENSOR, FUEL FEED LINE AND METHOD FOR MANUFACTURING A MEASURING SENSOR - A measuring sensor has a hollow body through which a fluid is able to flow. Two sections of a wall of the hollow body form electrodes for a capacitive and/or a resistive measurement and the electrodes are made of a conductive plastic.
