    Abstract: An electronics system communicates among its subsystems by a free-space optical bus. The bus transmits signals bidirectionally along a single linear axis as polarized beams of light. Each subsystem has a bus interface unit for generating outgoing beams along both axial directions, and for receiving incoming beams from both axial directions. The interface units use laser generators, photodetectors, and amplitude beam splitters.

    Abstract: An optical communication signal source package and assembly for coupling optical signals to the end of an optical fiber includes first and second semiconductor laser diodes capable of being operated in a redundant fashion for increased reliability or to provide wavelength division multiplexing for increases in bandwidth and information carrying capability. The laser diodes are supported with their mounting flanges in a common plane and are oriented to provide parallel beams of polarized light having perpendicular E-field vectors. A connector carried by the support positions the optical fiber at the target area where an optics system focuses the light beams. An optical coupling device such as a polarizing beam splitter or a holographic beam separator is responsive to the orthogonal light beams to direct both light beams toward the optical fiber with minimum decrease in amplitude. The package includes no moving parts or highly frequency selective components. The package is employed in a compact communication signal coupling assembly permitting short electrical lead lengths and high circuit density.

    Abstract: Attachment of electronics to optical devices is made by supporting the optical devices on a heat spreader card and the electronics on a separate circuit card. Each card has at least a first major surface, with an optical transducing subassembly mounted perpendicularly from the major surface of the heat spreader card. Electronics, except for transducing elements, are placed on the circuit card. The only direct attachment between the circuit card and the heat spreader card is one or more flexible cables attached to the respective major surfaces. This arrangement mechanically isolates the circuit card from the heat spreader card. The flexible cables include electrical conductors held positionally in a polyimide matrix, which provides for thermal isolation of the heat spreader card and the circuit card.

    Abstract: A method, system and computer program product are provided for implementing memory migration of large system memory pages in a computer system. A large page to be migrated from a current location to a target location is converted into a plurality of smaller subpages for a processor or system page table. The migrated page is divided into first, second and third segments, each segment composed of the smaller subpages and each respective segment changes as each individual subpage is migrated. CPU and I/O accesses to respective subpages of the first segment are directed to corresponding subpages of the target page or new page. I/O accesses to respective subpages of the second segment use a dual write mode targeting corresponding subpages of both the current page and the target page. CPU and I/O accesses to the subpages of the third segment access the corresponding subpages of the current page.
