The invention is directed to the automatic determination of a quantity which represents the rpm ratio between the transmission and the wheels. For this purpose, first and second rpm values are first detected which represent the rpm of at least one wheel and the rotational speed of a transmission component. Furthermore, a driving state quantity is formed which represents the instantaneous driving state of the motor vehicle. The essence of the invention is that a pregiven driving state can be determined when the formed driving state quantity indicates an essentially steady state driving state. The determination of the rpm transmission ratio which is sought takes place in dependence upon the detected rpm values when the pregiven operating state is detected. Furthermore, the invention relates to a stepped method which, for example, ensures a rapid determination of the differential transmission ratio after a transmission control apparatus is newly built in.

The present principles provide a way to place a multilevel grayscale image, visible with the bare eye in the data area of an optical disc. This feature can be used to authenticate a legitimate disc, since the image features are lost when copying a disc either with a PC recording drive or by a pirate creating a data set to be used on a laser beam recorder to produce forged ROM discs. The modulation rules are selectively varied during disc writing in a way to change the distribution of pit/land lengths, so that the at three (3) different diffraction properties are generated, and therefore produce at least three (3) distinct looks to the bare eye.

A system and method for replicating protected content on media includes a controller for enabling replicating of media content from partial encoded content received at a location of the controller. A media recorder is coupled to the controller and including a modulation process (104) to complete encoding of the partial encoded content to record media content on media readable by a device other than the media recorder.

An optical disc having a region with pre-recorded data and a recordable region, a method of fabricating the disc, a stamper for forming a disc master, and a recording device for use with the disc are disclosed. Data recorded in the recordable region may be used for activation of the disc, providing unique identification or enhancing program content on the disc.

A method for a driver assistance system of a motor vehicle includes the following steps: on the basis of a digital map of a navigation system, verifying whether there is a turn option, and, if there is a turn option, analyzing the dynamic data, measured by a locating system, of a preceding vehicle and calculating a turn probability for the preceding vehicle on the basis of these data.

The invention relates to a method for storing data in a prerecorded area of an optical recording medium, and to an optical recording medium having at least one prerecorded area in which data is stored according to the method. It is an object to propose a method for storing data in a prerecorded area of an optical recording medium using pits and lands, whereby the signal obtained from the pits and lands is compatible with a high frequency modulated groove signal. According to the invention, the pits and lands adjacent to bit cell signal transitions are arranged in a predefined manner, either in a fixed recurring sequence of pits and lands or symmetrically to the bit cell signal transitions.

The invention relates to a method and an arrangement for generating positionally-accurate print images on a carrier material with the aid of an electrophotographic printer or copier. A positioning error of the position of the carrier material with respect to a toner image present on the toner image carrier is determined, which error occurs during the contacting of a carrier material to be printed. Dependent on the positioning error determined, for every subsequent contacting of the carrier material to be printed with the toner image carrier, the position of the carrier material with respect to the toner image is adapted before the contacting such that the carrier material and the toner image are arranged with respect to one another substantially free of positioning errors.

A method and a device for controlling a drive unit which conveys a striplike laterally pre-printed recording medium, whereby a sensor is sensitized with respect to a regularly re-occurring mark of the recording medium. The recording medium is continuously scanned by the sensor during the printing operation and the speed at which the recording medium is conveyed is adjusted according to scanned signals from the sensor.

There are provided a method and apparatus for embedding a second level code into a first level code of an optical disc by data modulation rule variation. The apparatus includes a multi-level, varying rule based modulator (199) for modulating the first level code to obtain a channel bit stream representative of the first level code and having the second level code embedded therein. The multi-level, varying rule based modulator modulates the first level code using modulation rules respectively having different statistical properties of pit-land length distributions that preserve a readability of the first level code and that are distinguishable at readout of the optical disc. The different statistical properties represent binary or multilevel data of the second level code.
