Abstract: A system and method for providing an interpretable and unified representation for trajectory prediction that includes receiving birds-eye image data associated with travel of at least one agent within a roadway environment. The system and method also include analyzing the birds-eye image data to determine a potential field associated with the roadway environment and analyzing the birds-eye image data to determine a potential field associated with a past trajectory of the at least one agent. The system and method further include predicting a future trajectory of the at least one agent based on analysis of the potential fields.

Abstract: A file managing software program for managing a list of elements in a specific sequence in a first file of a computer program, including the steps of copying the first file to form a second file having an identical list of elements as the first file. The user is then permitted to rearrange the sequence of the elements of the second file independently of the sequence of the first file. A display of both the first and the second file list elements is provided to the user. Further embodiments allow the user to categorize, prioritize, and order according to users specified rules of how the second file element list is organized and displayed to provide a more convenient and flexible presentation of the file contents.

Abstract: A hand-powered riding device, in particular a self-propelled, wheeled riding device having a platform, a pulling rope and a pulley, is provided. The user, sitting or standing on the platform, pulls up the pulling rope wound around the pulley to cause the riding device to propel, simultaneously providing beneficial upper body exercise. The size of the said riding device is small, lightweight and portable.
