The Federal Aviation Administration is leading the National Airspace System modernization e ort, in part by supplanting traditional air tra c services with GPS aided by the Wide and Local Area Augmentation Systems (WAAS & LAAS). Making GPS the sole-means of navigation will enhance safety, exibility and e ciency of operations for all aircraft ranging from the single engine general aviation aircr...

New remote navigation systems have been developed to improve current limitations of conventional manually guided catheter ablation in complex cardiac substrates such as left atrial flutter. This protocol describes all the clinical and invasive interventional steps performed during a human electrophysiological study and ablation to assess the accuracy, safety and real-time navigation of the Cath...

Many of the current GPS (Global Positioning Systems) navigation aids use an audio method to deliver navigation information to the user. For the visually impaired person this method can be problematic. The visually impaired pedestrian relies heavily on information contained within the ambient sound environment; for location and orientation information, navigation information, and importantly, sa...
