This paper describes a real-time contact-free eye-gaze tracking system that bases its accuracy in a very precise estimation of the pupil centre. The eye camera follows the head movements maintaining the pupil centred in the image. When a tracking error is produced, the image from a camera with a wider field of view is used to locate the eye and quickly(More)
This study describes the validation of a near infrared spectroscopic method for monitoring a continuous manufacturing system. The achievement of this goal requires determining the near infrared (NIR) method’s accuracy, precision, obtaining an estimate of the sample volume analyzed, and the frequency with which measurements should be obtained. Five(More)
This paper presents an overview of a proposed protocol to provide application---transparent fault tolerant services in a Real Time Operating system. Fault tolerance is achieved by saving checkpoints of the processes belonging to a real time application. This approach proposes the extension of some real time system calls in order to save a recovery point(More)
