Abstract: An aviation performance evaluation methodology that can be implemented in various ways depending on the applications of interest. Baseline standards for expected performance are stored in one or more databases. One database may contain performance parameters and another database may contain baseline standards such as expert gaze data. Real-time actual performance data is acquired using an eye tracker system comprising at least one video camera, at least one infrared light source, and a computer system which receives image data from the video camera(s). More specifically, the actual and expected performance data are input to a computer system that is programmed to analyze the actual performance based on a comparison of the actual and expected performance data. Based on the results of the comparative analysis, context-adjusted inferences can be made regarding performance, adopted strategies, gaze scan quality, alertness or distraction, situational awareness, and workload.

Abstract: Configurable passive electromagnetic reflectors are disclosed, as are aircraft comprising configurable passive electromagnetic reflectors and methods to use configurable passive electromagnetic reflectors. In one embodiment a system comprises a reflector comprising a surface having a plurality of addressable patches switchable between a reflective state and a non-reflective state, and a controller coupled to the reflector to provide signals to switch the plurality of addressable patches between the non-reflective state and the reflective state to configure the reflector to selectively reflect incident electromagnetic radiation toward a remote target. Other embodiments may be described.
