Abstract: System and method for enhancing situational awareness. A moveable see-through display viewable by a user displays an augmented reality 2D image of an external scene based on received 2D image data, in accordance with updated position and orientation of display. The see-through display further displays an augmented reality 3D image of the external scene based on received 3D image data, the 3D image overlaid conformally onto view of external scene, in accordance with updated position and orientation of display. The see-through display further selectively displays: a gradual transition of the 2D image into the 3D image, or a gradual transition of the 3D image into the 2D image. At least one image feature may gradually appear or gradually disappear during the gradual transition. The 2D or 3D image may include a region of interest based on updated position and orientation of display or selected by user.

Abstract: Method and system for displaying augmented reality reflective of environmental features affecting visibility. Characteristics of a virtual object to be displayed on view of scene is determined. Environmental features affecting visibility along a line-of-sight from scene origin to virtual object are detected. When detected feature is at least one non-obstructing feature, its effect on visibility is determined, and virtual object is displayed superimposed onto view of scene such that appearance of virtual object is consistent with determined effect on visibility. When detected feature includes an amorphous obstructing feature, its range and contour is determined, and obstructed portions of virtual object is determined based on difference between range of virtual object and range of amorphous obstructing feature, and virtual object is displayed superimposed onto view of scene such that determined obstructed portions of virtual object appear obstructed in displayed view.

Abstract: System and method for determining the position and orientation (P&O) of a tool-tip relative to an eye tissue of interest. The system includes and imaging and tracking module coupled with a processor. The imaging and tracking module at least includes an imager. The imager acquires at least one image of at least one tissue-reference-marker. The imaging and tracking module further determines information relating to the P&O of the tool. The processor determines the P&O of the tissue-reference-marker according to the acquired image of the tissue-reference-marker. The processor determines the P&O of the eye tissue of interest, according to the P&O of the tissue-reference-marker, and a predetermined relative P&O between the tissue-reference-marker and the eye tissue of interest. The processor also determines the P&O of a tool-tip according to a tool-marker and determines the relative P&O between the tool-tip and the eye tissue of interest.

Abstract: Aspects of the invention are directed to a method and a system for detecting weakening of the adhesion strength between two or more joint surfaces of two or more structural elements. The system includes one or more Load Pins (LPs) and a controller. The one or more LPs may be inserted through the two or more structural elements such, perpendicular to the two or joint surfaces, such that no shear load is initially sensed by the LP. The system further includes a controller be configured to: upon receiving from the one or more LPs a shear load value, detect the weakening of the adhesion strength between the two or more joint surfaces.

Abstract: System for registering a coordinate system associated with a pre-acquired model of an object with a reference coordinate system. The system includes a portable unit which includes a display, a tracking system for tracking the portable unit and a processor. The processor is coupled with the portable unit and with the tracking system. The processor determines the position and orientation of the portable unit. The processor further determines the position of at least one marker located on the object according to at least one of, a tracked pointer and respective position related information. The processor further displays registration related information on the display. At least one of the registration related information and the display location of the registration related information are related to the position and orientation of the portable unit. The position of the at least one marker, in the coordinate system associated with the pre-acquired model, is predetermined.
