Abstract: A method for detecting the alertness of a vehicle driver includes the detection of a potentially dangerous situation by a system of the vehicle; the estimation of a visual observation field of the vehicle driver; and the detection of the alertness of the vehicle driver by comparing an orientation or a position of the potentially dangerous situation to the visual observation field of the vehicle driver.

Abstract: A method for ascertaining a height profile of a road situated ahead of a vehicle includes: reading in a movement profile of an object which is provided by an image sensor, the movement profile being read in as a plurality of images; reading in at least one parameter with regard to the object from a parameter sensor which is independent of the image sensor; and determining the height profile of the road situated ahead of the vehicle by using at least one vertical position of the object in the image and the parameter.

Abstract: A method for operating a drive motor of a drive system, including the following: providing a control variable, which is ascertained as a function of one or multiple state variable(s) of the drive system and as a function of a default variable, to an output stage for operating the drive motor; reading the control variable previously provided to the output stage back from the output stage to obtain a read-back control variable; ascertaining a back-calculated torque from the read-back control variable; comparing the back-calculated torque and a predefined monitoring torque; and providing the control variable or an alternative control variable ascertained from the monitoring torque to the output stage as a function of a result of the comparison for the purpose of operating the drive motor.

Abstract: A method is disclosed. The method includes receiving a first polygon, receiving a second polygon, calculating a vector joining a centroid of the first polygon and a centroid of the second polygon, retrieving vertices of each polygon that are farthest from the other polygon in the direction of the vector towards the other polygon, performing a view frustrum from each vertex retrieved for the first polygon to the centroid of the first polygon, performing a clipping operation on the second polygon and determining if the second polygon intersects the view frustrum of one or more of the vertices of the first polygon.

Abstract: Embodiments include storing graphics instructions at addresses in a memory in an original order, and storing in the memory pointers associated with each instruction pointing to the addresses of the instructions in the original order. A first pointer associated with a first graphics instruction may then be moved from pointing to a first address of the first graphics instruction to point to a second address of a second graphics instruction. Likewise, a second pointer associated with the second graphics instruction may be moved from pointing to the second address to point to the first address by accessing the first pointer before moving the first pointer to determine that the second pointer is to point to the first address (e.g., the address the first instruction points to before being moved). Afterwards, the instructions may be re-ordered into an optimized order for compiling, by switching them to different addresses according to the pointers.

Abstract: Apparatus, systems and methods for optimized frustum clipping via cached clip vertices are disclosed. For example, a method is disclosed, the method including generating a clip vertex for a leading edge of a triangle of a triangle strip or fan, indicating that the leading edge is shared with an adjacent triangle of the triangle strip or fan, and in response to the indication, using the clip vertex as a clip vertex of a trailing edge of the adjacent triangle in the triangle strip or fan. Other implementations are disclosed.

Abstract: Various methods, apparatuses, and systems are described in which subdivided polygons are derived from a first polygon. Bin assignments of subdivided polygons derived from a first polygon may be stored. One or more reference coordinate points associated with coordinates of the first polygon may be stored. One or more reference coordinate points associated with the coordinates of the first polygon on a subsequent frame may be compared to the stored one or more reference coordinate points from a previous frame. The bin assignments for the corresponding subdivided polygons for the subsequent frame may be reused if the results of the comparison are within a preset threshold quantity.
