A twin clutch transmission for a motor vehicle has two input shafts, two clutches, and driving shafts. The first input shaft can be actively connected to the first clutch, and the second input shaft can be actively connected to the second clutch. The first driving shaft is situated underneath the input shafts and the second driving shaft is situated above the input shafts, or vice versa. The input and driving shafts have intermeshing gear wheels, with fixed gears and loose wheels or idler gears. Each driving shaft has a gear wheel for transferring torque to the axle drive. A further shaft implements the reverse gear RG. A highly versatile and compact transmission is obtained by providing a third driving shaft that has a drive gear wheel for transferring torque to the axle drive, and the drive gear wheels of the driving shafts engage with an axle drive gear.

A method is proposed for characterizing a totality of particles (318). The method can be used in particular for charactering microparticular or nanoparticular aerosols. The method comprises the following steps: a) in a classification step, a class of the totality is selected, wherein the particles (318) of the selected class have a prespecified mobility dm; b) in a counting step, a number N of the particles (318) of the selected class is determined; c) in a charge determination step, a charge Q of the particles (318) of the selected class is determined; and d) in an evaluation step, at least one morphological parameter is determined from the charge Q, the number N and the mobility dm, wherein the morphological parameter comprises at least one item of information about an agglomerate state of the particles (318).

Managing channel element licenses for base transceiver stations. Preferred methods include license accounting at a BSC or MTS level, thereby providing better utilization of BTS channel element licenses in a wireless communication network. The BTS notifies a license manager whenever a channel element is put into use by transmitting a first channel element utilization message. If the number of available license has been not been exceeded, the license manager transmits a channel element utilization authorization message. If, on the other hand, the number of available license has been exceeded, the license manager transmits a channel element utilization denial message, instruction the BTS to terminate the call setup. Alternative embodiments include the BTS requesting a license using a first channel element utilization message and awaiting authorization prior to utilization of the channel element. The BTS preferably transmits a second channel element utilization message indicating the channel element is no longer in use.

摘要:
A method and apparatus for replacing lost PSTN data in a packet network and for generating variable power white noise are disclosed. In one embodiment, the method for replacing data includes the steps of receiving data packets, detecting lost data packets, and producing in response a lost data output indicating when replacement data needs to be provided. The method preferably generates the replacement data by re-using data stored in an extended playback buffer (with the re-used replacement data starting with the oldest output data byte stored in the extended playback buffer), and placing the re-used replacement data on an external network. Another aspect of the invention is a variable power white noise generator for providing replacement data. The variable power white noise generator may use, for example, a multi-bit register that stores a magnitude, and a pseudo-random sign bit generator to change the positive and negative sense of the magnitude. In one preferred embodiment, a linear feedback shift register (LFSR) is used in conjunction with a feedback network corresponding to a polynomial generating function. The pseudo-random output sequence of the LFSR then produces a pseudo-random output bit to control the positive and negative sense of the magnitude bits.
