Abstract: The performance of a computer system displaying polygonal forms is improved by method and apparatus including a cache storage device and related control hardware operating in conjunction with a pipeline graphics display system to reduce or eliminate the redundant matrix transformation of shared vertex data, thereby reducing the processing time required to generate the graphics images displayed for out-the-window simulation.

Abstract: A method is employed for pre-assignment and pre-scheduling of tasks that enables allocation across multiple physical processors arranged in a variety of architectures. The method comprises the steps of: constructing a DFG of tasks to be performed to provide a solution for a problem; determining cost values for each task and the overall problem, such cost values taking into account a target multiprocessor architecture and factors such as elapsed task execution times. The method pre-assigns the tasks to logical processors and assures that inter-dependent tasks are executable by logical processors that are within required communications delay criteria of each other. The assigning action attempts to arrive at a minimal cost value for all tasks comprising the problem. The pre-assigned tasks are then pre-scheduled based upon a performance criteria and are converted to machine code. The machine code is then deployed to physical processors in the target multi-processor architecture.

Abstract: A crash test dummy lower leg structure having a lower leg unit consisting of a tibia member provided with upper and lower tibia sensors. An ankle-foot assembly connected to the lower tibia sensor has a ball and socket connection between the ankle shell and foot member. Means are provided to restrict movement of the ball, to which the foot member is connected, to rotation about three mutually perpendicular axes which intersect at the center of the ball. A knee clevis sensor is connected to the upper tibia sensor and has a pair of spaced parallel members designed to sense and measure force along a line between the knee pivot and the ankle pivot.
