Card cage system

Abstract: A card cage system is provided that includes a middle card guide interposed between two end card guides in an electronic equipment enclosure. Each of the card guides includes one or more channels adapted to receive a card edge. The middle card guide includes a removable adapter element that, when present in the middle card guide, prevents insertion of double wide, or larger, cards while, at the same time, permitting insertion of two single wide cards in a side-by-side arrangement. When the adapter element is removed, a double-wide card can be received in the middle card guide such that it straddles the middle card guide. The edges of the double-wide card are received in the first and second end card guides. Thus, the card guide can be readily customized to accommodate a variety of card types and sizes, in various arrangements.

Secure access to segment of data storage device and analyzer

Abstract: The present invention relates to data security. A data storage device can include an insecure portion and a secure portion of its storage medium. A controller can control access to the storage medium by a computer operating system and communicate a signal to the computer operating system that describes portions of the storage medium, but do not describe the secure portion of the storage medium. Methods for managing access to data stored on a partitioned data storage device, methods for partitioning a data storage device, and methods for monitoring communication between a computer and a data storage device are described.

Compact optical transceivers for host bus adapters

Abstract: An optical transceiver is provided that includes a transceiver substrate arranged substantially perpendicular to longitudinal axes respectively defined by a transmit optical subassembly and receive optical subassembly. The transceiver substrate is configured to electrically and physically connect to the transmit optical subassembly and the receive optical subassembly, and includes a connector configured and arranged to interface with a host bus adapter. The combination of the host bus adapter and optical transceiver is sized and configured to be received within a standard slot of a host system, such as a PCI or PCMCIA slot. In this way, one or more optical connections are integrated within the host device or system.

Synchronous network traffic processor

Abstract: A synchronous network traffic processor that synchronously processes, analyzes and generates data for high-speed network protocols, on a wire-speed, word-by-word basis. The synchronous network processor is protocol independent and may be programmed to convert protocols on the fly. The synchronous network traffic processor includes a data compare unit (110) a data modify unit (120) an execution control unit (130) a peripheral unit (140), an input pipeline unit (150), an instruction memory (160) and a bank of general purpose registers (170). An embodiment of the synchronous network processor described has a low gate count and can be easily implemented using programmable logic. An appropriately programmed synchronous network traffic processor may replace modules traditionally implemented with hard-wired logic or ASIC.

Sub-banded / single-sub-carrier drop-demux and flexible spectral shaping with a fine resolution photonic processor

Abstract: Spectral processor based on arrayed waveguide grating and free-space manipulation is capable of arbitrary filtering at record metrics of 0.8GHz resolution over 200GHz span. Narrowband coherent drop-demultiplexing and controlled optical shaping is demonstrated in unison with digital sub-banding.
