Abstract: The present publication describes a data transfer method and system in a digital sound reproduction system. The method comprises method steps for generating a digital audio stream for multiple channels in a host data source, e.g. a computer, the audio stream is formed by multiple consecutive samples, receiving the digital audio stream sent by the host data source through a digital data transmission network by several digital receivers each of which including a microcontroller with a clock, the receivers further including means for generating an audio signal.

Abstract: A navigation system using a mobile terminal, GPS receiver and navigation software, wherein the navigation software is arranged to switch the mobile terminal into a power saving mode if there are no further instructions needed for a determined period of time or distance. The power saving functionality comprises turning the backlight off and changing the visualization of the display for better readability without the backlight.

The method comprises method steps for generating a digital audio stream for multiple channels in a host data source, e.g. a computer (1), the audio stream is formed by multiple consecutive samples, receiving the digital audio stream sent by the host data source (1) through a digital data transmission network by several digital receivers (2) each of which including a microcontroller with a clock, the receivers (2) further including means for generating an audio signal.

Abstract: A navigation system using a mobile terminal (14), GPS receiver (13), navigation server (15) and navigation software, wherein the navigation software is arranged to detect defects in navigation or driving conditions data. Defects in the navigation or driving conditions data are detected by comparing the actual behavior of the user with the route computed and sug-gested by the navigation software. The difference be-tween the actual route taken by the user and the com-puted route is detected and sent to the navigation server (15). The navigation server (15) then collects statistical information on such locations on the map where users repeatedly choose a different route from the computed route and determines, based on the sta-tistics, the possible defect in the navigation or driving conditions data.

Abstract: The route computing method and software using a two-step routing procedure. First the navigation software computes a temporary route using road segments having a predetermined road classification. This simplifies the routing as the amount of the roads is minimized. The result is rough and it must be further computed for achieving the best possible result. For computing the best possible result the navigation software determines a distance parameter. The parameter determines the distance that is used for further computing from the temporary route. Then the further computation can be focused on a geographical area with a complete set of roads and streets.

Abstract: A vehicle tracking method using a route model for estimating the exact location of the tracked vehicle. The estimated location is computed in the vehicle by tracking device (14) and in the tracking center (15). The tracking device acquires the exact location with positioning means (13). Then the tracking device compares the difference between the computed location and the computed location to a threshold value. If the threshold is exceeded, the exact location will be sent to the tracking center.

Abstract: A method is provided for intercepting network packets in a computer system, where a number of functions are used to communicate network packets between a network adapter and a protocols entity. A first network adapter and a first protocols entity installed in the computer system are identified. A set of replacement functions is provided within a packet interceptor module. At least one function used for transmitting network packets from said first protocols entity to said first network adapter is hooked into a first replacement function. At least one function used for transmitting network packets from said first network adapter to said first protocols entity is hooked into a second replacement function. At least one function used for receiving information about the status of the network interface implemented by said first network adapter is hooked into a third replacement function.
