| 20090180627 | Active sound blocker - A noise reduction system for actively blocking a noise source for a means of transport. The noise reduction system comprises at least one counter sound source and at least one intensity sensor. The at least one counter sound source and the at least one intensity sensor are arranged in a measuring region. In the measuring region, measuring of the noise intensity of the noise source and measuring of the counter sound intensity of the counter sound source are by the intensity sensor. Based on the measured noise intensity and the counter sound intensity, the counter sound source is controllable such that the sound energy input of the noise source can be globally reduced by the counter sound source. | 07-16-2009 |

| 20080196967 | Active Countersound System with Special Arrangement of the Secondary Actuators for Reducing the Passage of Sound at an Open Boundary Area of Two Volumes; Active Countersound Arrangement; Method for Actively Reducing Sound - An active countersound system for actively reducing the sound waves of primary sound waves, with a regulator unit, an error sensor, a reference sensor and several secondary actuators. The secondary actuators are designed to emit countersound waves, wherein the regulator unit, which is coupled to the secondary actuators, processes an error signal and a reference signal, and generates a secondary signal, which by way of the coupling is conveyed to the secondary actuators in order to control the secondary actuators by means of the secondary signal such that said secondary actuators generate countersound waves that reduce the error signal so that optimal sound wave abatement is implemented, wherein the secondary actuators are arranged such that they are located on the margin of an open passage area, which passage area comprises a margin and is to be penetrated by the primary sound waves, in order to ensure active sound wave abatement of the open space that in the direction of passage is arranged behind the open passage area, of the countersound waves in the manner of a curtain. | 08-21-2008 |

| 20110117932 | METHOD FOR CHECKING THE LOCATION OF A FEMTOCELL - A method for checking the location of a femtocell includes receiving, by the femtocell and by a reference receiver having a known location, radio signals from at least three transmitters disposed at known locations. Each of the transmitters is at least one of a broadcast transmitter and a pilot radio signal transmitter configured to broadcast a pilot radio signal for checking the location of the femtocell in a frequency range outside frequency ranges used for mobile communication. Differences in delay of the radio signals from two of the at least three transmitters are determined based on reception times of the radio signals received by the femtocell and the reference receiver. The location of the femtocell is checked based on the determined differences in delay. | 05-19-2011 |

| 20080245059 | Method For Operation of an Internal Combustion Engine and Device For Carrying Out the Method - A method for operation of an internal combustion engine, comprising an exhaust treatment device in the exhaust system thereof, with application of a reagent under given operating conditions of the internal combustion engine and/or the exhaust treatment device and a device for carrying out the method are disclosed, wherein a correction parameter is determined for a reagent signal, describing the amount of reagent to be introduced into the exhaust system and the correction parameter is determined by means of a comparison of a measure of the actual amount of the reagent in the exhaust system, which should be introduced based on a measure of a pre-determined set amount and the measure of the set amount. The above method permits a particularly exact maintenance of the amount of reagent introduced into the exhaust system in accordance with the pre-determined measure for the set amount. | 10-09-2008 |
| 20100004842 | Diagnostic Method and Device for Controlling an Internal Combustion Engine - A device and a method for controlling an internal combustion engine, in which an actual value is determined based on a lambda value and compared with a setpoint value. Based on the comparison, a correction value for a controlled variable is determined and stored. An error is detected if the correction value changes abruptly. | 01-07-2010 |
| 20100152994 | METHOD FOR ASSESSING A METHOD OF FUNCTIONING OF A FUEL INJECTOR IN RESPONSE TO THE APPLICATION OF A CONTROL VOLTAGE, AND CORRESPONDING EVALUATION DEVICE - A method for assessing a method of functioning of a fuel injector in response to the application of a control voltage to at least one actuator of the fuel injector, including the steps of applying the control voltage to the at least one actuator of the fuel injector for a no-torque-generating injection into an engine, determining a fuel content in an exhaust tract disposed at an engine, comparing the determined fuel content with a specified comparison value, and assessing the method of functioning of the fuel injector based on the comparison result. Furthermore, also described is an evaluation device for assessing a method of functioning of a fuel injector in response to the application of a control voltage. | 06-17-2010 |
| 20100191443 | METHOD FOR THE DETERMINATION OF AN INJECTED FUEL MASS OF A PREINJECTION - A method for the determination of a fuel mass of a pre-injection injected into at least one combustion chamber of an internal combustion engine by means of at least one injection under high pressure is characterized in that a corrective variable is determined for the pre-injection by means of a comparison between a measure for the actual amount of injected fuel of at least one test post-injection carried out for a predetermined target amount of a desired pre-injection due to a measure, and the measure for the target amount. | 07-29-2010 |
| 20100275885 | Method for Determining an Opening Voltage of a Piezoelectric Injector - A method for determining an opening voltage of an injector having a piezo actuator, in particular an injector of an internal combustion engine, in which an output voltage is applied at the piezo actuator in the closed state of the injector, and the voltage is lowered by energizing the piezo actuator so as to open the injector. The energy supply is interrupted at a holding voltage and the voltage change present at the piezo actuator is then measured over the time, the reaching of the opening voltage being inferred in the case of a voltage rise. | 11-04-2010 |
