Abstract: Presented herein are optical module cage designs and heatsink configurations for improved air cooling of pluggable optical modules disposed within the optical module cages. The designs and configurations presented herein facilitate efficient air cooling of higher power pluggable optical modules by enhancing airflow through the optical module cages, increasing contact between the optical modules and the heatsinks, and/or increasing the heatsink dissipation surface area.

Abstract: A system and method are provided for using a computer system to assist in planning a trajectory (960A, 960B) for a surgical insertion into a skull. The method comprises providing the computer system with a three-dimensional representation of the skull and of critical objects located within the skull, wherein the critical objects comprise anatomical features to be avoided during the surgical insertion. The method further comprises providing the computer system with a target location (770, 970) for the insertion within the skull. The method further comprises generating by the computer system a first set comprising a plurality of entry points, each entry point (760) representing a surface location on the skull, and each entry point (760) being associated (2D) with a trajectory (960A, 960B) from the entry point (760) to the target location (770, 970).

Abstract: An optical switching node and method for operating same is disclosed. If a signal received over an optical fiber is destined for the switching node at which the signal is received, the signal is processed conventionally. If there is a signal on the fiber that is destined for a different optical switching node, then a node controller will determine whether that signal requires equalization and/or regeneration. A network manager instructs the node controller whether the signal requires wavelength conversion. In accordance with the invention, if the optical signal on the fiber is destined for a different optical switching node and requires none of equalization, regeneration and wavelength conversion, the optical signal remains in the optical domain and is switched directly to an appropriate output fiber.
