20090221328 | METHOD FOR OPERATING A MOBILE COMMUNICATIONS SYSTEM AND CORRESPONDING SYSTEM MOBILE COMMUNICATIONS SYSTEM - The invention relates to a method and device for operating a mobile communications system, which comprises a multitude of radio cells and at least one mobile communications terminal with a subscriber identification module, the operation ensuing according to the whereabouts of the communications terminal. According to the invention, at least one subscriber area is established within a geographic total area covered by the mobile communications system and determines those radio cells that are located at least partially within the subscriber area. The cell identifications of the determined radio cells are transmitted to the communications terminal and subscriber identification module of the subscriber and are stored there. A comparison then ensues of the correspondence of the cell identifications of the radio cells, which currently sense the communications terminal, with the cell identifications stored in the subscriber identification module whereby, if appropriate, a special operating mode is switched to that is assigned to the subscriber area. | 09-03-2009 |

20110224812 | METHOD AND ARRANGEMENT FOR THE AUTOMATIC OPTIMIZATION OF THE TRANSFER FUNCTION OF A LOUDSPEAKER SYSTEM - In the case of a method for optimizing the transfer behavior of loudspeaker systems in a consumer electronics device, the actual transfer function of the loudspeaker system to be optimized is determined, in that a test signal is reproduced on the loudspeaker system either directly or via audio signal processing stages (DSP, amplifier, etc.) installed in the device, and the acoustic signal emitted by the loudspeaker system is captured by means of microphone and the actual transfer function is determined from the measurement values. Furthermore, in the method, a code for a DSP algorithm is generated and optimized to the extent that, in the case of a previously set maximum deviation from the desired transfer function, the fewest DSP resources are needed. The completely optimized code is loaded into the DSP of the device and activated. A corresponding arrangement has a microphone, a measurement unit, a DSP code generator, and an interface that loads the generated DSP code into the connected consumer electronics devices. | 09-15-2011 |

20150231779 | HANDLE FOR A WORK APPARATUS HAVING A DRIVE MOTOR - A handle for a work apparatus has an actuation member for controlling the rpm of a drive motor of the work apparatus. The actuation member is mounted in the handle and has a pressure surface for the fingers of a user hand. In an initial position, the actuation member protrudes with its pressure surface beyond the grip surface of the handle and, in a position for continuous operation of the motor, has dipped into the grip surface so that the pressure surface of the actuation member lies at the level of the grip surface. A recess extends in the longitudinal direction of the handle and is formed in the grip surface. The recess overlaps the pressure surface of the actuation member so that the actuation member is displaced into the handle via the recess to a boost position whereat the pressure surface lies within the grip surface. | 08-20-2015 |
