  • Patent number: 8393852
    Abstract: The turbocharger having a device for detecting a malfunction of the turbocharger, particularly a malfunction of at least one bearing of the turbocharger has the following features: The device for detecting a malfunction of the turbocharger has a memory device, in which the target operating states of an intact turbocharger are stored. The device for detecting a malfunction of the turbocharger further has a comparing device, in which the determined actual operating state of the turbocharger is compared to a corresponding target operating state of an intact turbocharger. The turbocharger further has a measuring device for determining an actual operating state of the turbocharger, wherein the device for detecting a malfunction of the turbocharger emits an error message if the comparing device detects that the actual operating stage deviates from the target operating state by a predefined measure.

  • Patent number: 7751515
    Abstract: Mobile handheld terminals receiving DVB transmission require relatively low power consumption and TDM based transmission can be used to reduce power of the terminals. In order find pilot carrier position at least two symbols are accessed which are adapted to establish a correspondence pattern for pilot carriers in a matrix of the at least two symbols. Carriers of the first symbol are correlated with the corresponding carriers of the second symbol within the matrix for determining a correlation maximum for indicating a pilot carrier position.

  • Publication number: 20090210147
    Abstract: An apparatus for enabling generation of a map using perpendicular projection to merge data may include a processor. The processor may be configured to receive an indication of a first trace defining a first position history and a second trace defining a second position history, perform a perpendicular projection calculation with respect to portions of the first and second traces, and merge the first trace and the second trace on the basis of the perpendicular projection calculation.

  • Publication number: 20080052336
    Abstract: An approach is provided for reducing latency in fast Fourier transformation (FFT) related systems, such as orthogonal frequency division multiplexing (OFDM) systems. In a first processing direction, an interleaving processing is performed to obtain an interleaved data sequence which is then subjected to an inverse fast Fourier transformation processing, wherein the interleaving processing comprises a bit re-ordering processing of the inverse fast Fourier transformation processing. In an opposite second processing direction, a fast Fourier transformation processing is performed with a bit-reversed output data sequence which is then subjected to a de-interleaving processing, wherein the de-interleaving processing comprises a bit re-ordering processing required for re-ordering said bit-reversed output data sequence. The combined interleaving/de-interleaving and reordering processing leads to a reduced latency and saves memory space.

  • Patent number: 5726310
    Abstract: 2-(2,4-Dihydroxyphenyl)-4,6-bis(2,4-dimethylphenyl)-s-triazine is prepared by reacting cyanuric chloride with m-xylene at a temperature of 0.degree.-110.degree. C. in the presence of a Lewis acid and at least one inert chlorinated aromatic solvent to give the intermediate 2-chloro-4,6-bis(2,4-dimethylphenyl)-s-triazine. This intermediate, without being isolated, is then reacted with resorcinol to give the final desired product 2-(2,4-dihydroxyphenyl)-4,6-bis(2,4-dimethylphenyl)-s-triazine in good yield.
