Abstract: A system for protecting the safety of occupants exiting and entering a vehicle is disclosed. The system has sensors on the interior, exterior and remotely of the vehicle and one or more imaging devices that project an image onto the pavement supporting the vehicle as well as optional data input devices all communicating with a system controller. The system anticipates that the occupant will be leaving the vehicle and the time it will take for the occupant to fully exit the vehicle. The system further controls the imaging devices to warn the drivers of oncoming traffic of the occupant's egress and warn or block the egress of the occupant should a particularly dangerous condition exist.

Abstract: A system for authenticating electronic devices, particularly chips or integrated circuits is described. This allows authenticating that the devices are authorized by the original manufacturer for operation in critical applications.
