Abstract: A user monitoring system receives a first data stream from a first recording device and a second data stream from a second recording device. Each of the first data stream and the second data stream include data relating to an eye of the user. The first data stream and the second data stream overlap temporally. The system processes the first data stream to determine a first blink sequence of the user, processes the second data stream to determine a second blink sequence of the user, and compares the first blink sequence and the second blink sequence to detect a blink pattern present in both the first blink sequence and the second blink sequence. The system determines a temporal offset of the first data stream and the second data stream by comparing respective positions of the blink pattern in the first data stream and the second data stream.

Abstract: A development system with methodology for run-time restoration of UML model from program code is described. In one embodiment, for example, in a computer system, an improved method is described for developing and executing an application, the method comprises steps of: creating a model describing business objects and rules of the application; creating source code for the application, including representing the model within the source code itself; compiling the source code into an executable application; running the executable application on a target computer in conjunction with a run-time framework that provides services to the executable application; and while the executable application is running, reconstructing the model from the executable application and making it available to the run-time framework.
