Title: System for creating control structure for versatile content control
Inventor: JOGAND COULOMB FABRICE
IPC: G06F21/62
Filed: 2005-12-21
Abstract: The mobile storage device may be provided with a system agent that is able to create at least one hierarchical tree comprising nodes at different levels for controlling access to data stored in the memory by corresponding entities. Each node of the tree specifies permission or permissions of a corresponding entity or entities for accessing memory data. The permission or permissions at the node of each of the trees has a predetermined relationship to permission or permissions at nodes at a higher or lower or the same level in the same tree. Thus, the mobile storage devices may be issued without any trees already created so that the purchaser of the devices has a free hand in creating hierarchical trees adapted to the applications the purchaser has in mind. Alternatively, the mobile storage devices may also be issued with the trees already created so that a purchaser does not have to go through the trouble of creating the trees. In both situations, preferably certain functionalities of the trees can become fixed after the devices are made so that they cannot be further changed or altered. This provides greater control over access to the content in the device by the content owner. Thus, in one embodiment, the system agent can preferably be disabled so that no additional trees can be created.

Abstract: A wireless communication system for transmitting signals to a plurality of mobile terminals by use of multiple antennas. The reception qualities of signals, which are transmitted from the antennas of the transmitting end, at the mobile terminals are determined. A main antenna is decided based on the reception qualities during a real time communication. The multidimensional correlation between the main antenna and each of the other antennas is calculated. An area, in which the multidimensional correlation is lower than a predetermined value, is selected. Date, which identifies the main antenna, the low correlation area and the reception quality, is fed back to the transmitting end. An antenna forming the low correlation area is selected as a diversity antenna by the transmitting end. The diversity antenna and the main antenna are used to perform a diversity transmission of signals to the mobile terminals.
