Abstract: A computer-implemented method for optimizing the memory of a partitioned system including multiple memories, at least one processing core, and at least one memory protection unit (MPU), each MPU including multiple registers. The method includes calculating run-time changes of each piece of data of a multitude of data which are to be processed by the processing core, with the respective piece of data being placed in each memory of the multiple memories based on access statistics for the respective piece of data, each piece of data of the multitude of data being assigned to one rights area or multiple rights areas; determining a placement of the data in the memories based on the calculated run-time changes; and allocating the multiple registers of the MPU for the certain placement of the data in the multiple memories, one register of the multiple registers identifying a memory area of the multiple memories.

Abstract: An airbag of a vehicle occupant restraint system has an actively releasable tether element (14) disposed in an interior (16) of the airbag (10) which is connected, at an airbag-side fixation (18), permanently to the airbag (10) in the region of a contact zone (20) for the occupant, and which comprises a detachable fixing point (22) for the release. The airbag (10) can take up a smaller first filled volume (V1) in which the tether element (14) and the detachable fixing point (22) are not released, and a larger second filled volume (V2) in which the tether element (14) is released at the actively detachable fixing point (22).

Abstract: A vehicle occupant restraint device comprises a control unit and a group of at least two matched airbags (20, 24; 22, 26) for the protection of a vehicle occupant (10; 16) on a particular vehicle seat (12; 16). The control unit is arranged and the airbags (20, 24; 22, 26) are disposed and designed so that, in a collision case, the control unit differentiates between a first situation in which the vehicle occupant (10; 16) is located in a standard distance area relative to a first airbag (20; 22) and a second situation in which the vehicle occupant (10; 16) is located in a rear area which is further distant from the first airbag (20; 22) than the standard distance area. When the first situation is given, the control unit activates the first airbag (20; 22) only. In contrast, when the second situation is given, the control unit activates the first airbag (20; 22) and additionally at least a second airbag (24; 26) of the group, with the first airbag (20; 22) backing the second airbag (24; 26).
