Abstract: A microcontroller unit includes at least one core, a plurality of safety fault management units, with each safety fault management unit including circuitry to detect one or more safety faults and to output an alarm signal in response to detection of one or more safety faults. The microcontroller further includes system control units operating in parallel to the at least one core. Each of the plurality of system control units can be coupled to at least one of the safety fault management units and can include hardware circuitry to generate and output a port emergency stop (PES) signal based on the alarm signals obtained from a safety fault management unit. The microcontroller includes port circuitries coupled to ports and to the system control units. The port circuitries can selectively cause a respectively connected port to enter a non-operational electronic state in response to receiving a PES signal.

Abstract: A processor-implemented method of detecting a moving object includes: estimating a depth image of a current frame; determining an occlusion image of the current frame by calculating a depth difference value between the estimated depth image of the current frame and an estimated depth image of a previous frame; determining an occlusion accumulation image of the current frame by adding a depth difference value of the occlusion image of the current frame to a depth difference accumulation value of an occlusion accumulation image of the previous frame; and outputting an area of a moving object based on the occlusion accumulation image.
