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: A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.

Abstract: A first thermal management approach involves an air flow through cooling mechanism with multiple airflow channels for dissipating heat generated in a PCA. The air flow direction through at least one of the channels is different from the air flow direction through at least another of the channels. Alternatively or additionally, the airflow inlet of at least one channel is off-axis with respect to the airflow outlet. A second thermal management approach involves the fabrication of a PCB with enhanced durability by mitigating via cracking or PTH fatigue. At least one PCB layer is composed of a base material formed from a 3D woven fiberglass fabric, and conductive material deposited onto the base material surface. A conductive PTH extends through the base material of multiple PCB layers, where the CTE of the base material along the z-axis direction substantially matches the CTE of the conductive material along the x-axis direction.

Abstract: Method for verifying registration of a model of an internal-body-part with the internal-body-part in a reference coordinate system. The internal-body-part is at least partially unseen directly by a user. The method includes the procedures of continuously determining a position and orientation of a head-mounted-display in the reference coordinate system, determining a display location of at least one virtual marker, and displaying the virtual marker according to the display location. The display location of the virtual marker is determined according to the expected position of a respective at least one reference point relative to the head-mounted-display. The reference point is directly visible to the user. The relative position between the reference point and the internal-body-part is substantially constant. The position of the reference point in the reference coordinate system is predetermined. When the model and the internal-body-part are effectively registered, the reference point and corresponding virtual marker appears visually in alignment.

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.
