Abstract: A learning controller overcomes tuning problems in vehicle simulation programs by estimating requisite vehicle-specific parameters, effectively learning from its mistakes, as the vehicle is automatically driven around a track. After a sufficient period of calibration, the learned parameters are automatically saved to a car-specific file. The file parameters may be loaded in the controller in the future to optimally control a vehicle without the need to re-run the learning procedure.

Abstract: An image background maintenance system and method for maintaining a background model of an image sequence by processing on multiple spatial scales. These multiple spatial scales include a pixel scale, a regional scale and a frame scale. The image sequence undergoes pixel processing that determines a current background model and provides an initial pixel assignment as either a background or a foreground pixel. Region processing further refines the initial pixel assignments by considering relationships between pixels and possibly reassigning pixels. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.

Abstract: A system and process for automatically initiating and terminating associations between a computer input device of some type (e.g., computer mice, keyboards, trackballs, and the like) and a computer in a computing space that can have many such devices and several computers. In this way, input devices can be used to interface with any of the computers in the space. For instance, a user could move about a room filled with computers and their respective computer monitors, with a wireless mouse, and interface with the various computers using the mouse. To this end, the aforementioned association entails redirecting signals generated by a computer input device from one computing device in a computing space to another computing device in the space. The association is either initiated or terminated depending on whether sets of preconditions have been satisfied.
