Abstract: A secure digital data distribution system (100) for preventing unauthorized access to digital data. The system utilizes an identification system module (116) embedded in a digital storage media (114) to grant authorization to media players (118). Prior to reading the digital data recorded on the media (114), an identification system interrogator (122) reads authorization data from the identification system module (116) to determine whether the media player (118) is authorized to read the media (114). If the authorization data matches the media player's unique identifier, authorization is granted and the media player (118) commences to read the media (114).

Abstract: A computer system having a visual display which displays data in an interactive split pie chart and permits a user to modify the input parameters of the pie chart to dynamically alter the configuration of the chart. The split pie chart can be split into two or more sections each corresponding to a different time period. Each section is divided into wedges corresponding to different variables and their corresponding values in two different time periods. Finally, the chart itself is geographically placed on a graphic image of a map. An interface between the computer system and a data storage system to transfer data to be transformed into the graphical representation of the pie chart is provided. The user modifies the input parameters of the pie chart through a user interface which translates the modifications into queries to the database storage system to retrieve the appropriate data.

Abstract: In a method and device for feeding fuel into a combustion chamber of a cylinder of an internal combustion engine the following steps are discerned to withdraw a small amount of compressed hot gas via a valve opening into the combustion chamber of the cylinder during one working cycle, to store this small amount of hot gas withdrawn, in a valve chamber of the valve, to inject fuel into this valve chamber containing the small amount of hot gas, building a fuel-gas mixture, and to inject the fuel-gas mixture through the valve opening into the combustion chamber of the cylinder during next working cycle of the internal combustion engine.
