This paper presents a triple-mode average current control (TACC) strategy to achieve unity power factor and reduce the current stress for a boost PFC converter.The controller switches among different modes in each half-line cycle, and smooth transition is ensured by mapping of the operation region.By adaptive mode shifting, it reduces the current s
Face Interface is a wearable prototype that combines the use of voluntary gaze direction and facial activations, for pointing and selecting objects on a computer screen, respectively.The aim was to investigate the functionality of the prototype for entering text.First, three on-screen keyboard layout designs were developed and tested (n=10) to find
