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.

Abstract: Method and system for displaying virtual environment during in-flight simulation. A simulation environment is selected for a training simulation of an airborne platform operating in flight within a real environment. The position and orientation of a display viewable by an operator of the airborne platform is determined with respect to the selected simulation environment. The display displays at least one simulation image comprising a view from a virtual altitude of simulation environmental terrain in the selected simulation environment, while the airborne platform is in flight at a real altitude above the real environmental terrain in the real environment, the virtual altitude above the simulation environmental terrain being a lower altitude than the real altitude above the real environmental terrain. The simulation image is displayed in accordance with the determined position and orientation of the display, such that the simulation environment is adaptive to operator manipulations of the airborne platform.

Abstract: Optical systems and methods are provided, which combine see-through view of the real world and display source images using a conical optical combiner cut to have flat surfaces normal to the viewer line of sight. The conical shape minimizes interferences in the view of the real world as the edges of the optical combiner are tangent to the viewer vision field of view and the inner part of the optical combiner is semitransparent. Additionally, the optical system comprises a beam splitter, a shutter(s) for attenuating or blocking the see-through path and may employ polarizing element to improve the contrast between the scene observation and the projected display and thus enabling selective viewing of either. The system may also be configured to enable diopter adjustment and virtual display distance adjustments.
