  • Publication number: 20240097646
    Abstract: Aspects of the disclosure relate to wireless communication, and high-frequency filters with resonators. One aspect is a device including first and second busbars, and electrode fingers coupled between the busbars, with electrode fingers extending different distances toward an opposite busbar such that a second end of each of the electrode fingers collectively form wave shapes. The device further includes pluralities of gap reflectors positioned between the wave shapes and a nearest busbar.

  • Publication number: 20070209636
    Abstract: In a method for operating an internal combustion engine, in particular an auto-ignition internal combustion engine, having at least one combustion chamber in which an air/fuel mixture is formed, and recirculated exhaust gas is admixed to the combustion air, a base setting of the exhaust gas recirculation rate is established as a function of a first characteristic operating variable, the exhaust gas recirculation rate is adjusted depending on at least one of the first and a second characteristic operating variable, and, in order to optimize combustion, the exhaust gas recirculation rate is adjusted a second time on the basis of a combustion noise measurement.

  • Publication number: 20050145022
    Abstract: In a device for determining an exhaust gas recirculation rate (EGR) in an internal combustion engine, wherein the device includes a sensor unit, which in a first region is exposed to an exhaust-gas atmosphere from an exhaust gas recirculation line and in a second region is exposed to an exhaust gas/fresh air atmosphere in an intake line of the internal combustion engine downstream of a location where the exhaust gas recirculation line opens into the intake line, the sensor unit disposed in the intake line is tubular with the inner side of the sensor unit being exposed to the exhaust gas atmosphere and the outer side of the sensor unit being exposed to the exhaust gas/fresh air atmosphere. The sensor unit is preferably positioned centrally within the intake line away from the wall of the intake line.
