Abstract: A datacenter schedules and executes requests to conserve energy. The datacenter uses an event-based opportunistic approach to schedule and run the requests, which provides energy efficiency. The requests are hierarchically batched and sent to the datacenter for scheduling and execution. They are selectively sent over low power links and selectively serviced by low power processors.

Abstract: An integrated optical I/O and semiconductor chip with a direct liquid jet impingement cooling assembly are disclosed. Contrary to other solutions for packaging an optical I/O with a semiconductor die, this assembly makes use of a metal clad fiber, e.g. copper, which will actually enhance cooling performance rather than create a design restriction that has the potential to limit cooling capability.

Abstract: A method and systems for a frequency locked feedback loop for wireless communications are provided. The method includes applying dither modulation from a harmonic modulator to modulated data at a transmit source, and mixing the dither modulation at a dither modulation frequency with the modulated data at a wireless carrier frequency to produce a modulated signal. The method also includes filtering and splitting the modulated signal using a bandpass filter to produce a wireless output signal and a feedback signal. The method further includes determining a frequency error in the feedback signal as a function of alignment of the wireless carrier frequency to a target frequency in a frequency response of the bandpass filter. The method additionally includes adjusting the wireless carrier frequency in response to the frequency error to establish a frequency lock between the wireless carrier frequency and the target frequency.

To maintain consistency, adaptive caching structures are used. The members of an adaptive caching structure are selected based on a sharing context, such as those members having a chosen association identifier or those members not having the chosen association identifier.

Abstract: Methods and systems for fabrication of injection molded optical components are disclosed. In one embodiment, a moldplate having one or more cavities is configured to receive injected optical material within walls of the cavities. The cavities are designed with a predetermined geometric profile approximately corresponding to a predetermined optical profile of an optical element to be formed therein. When molten optical material is injected into the cavities of the moldplate, the injected optical material forms a meniscus due to surface tension between the optical material and the wall of the cavities. The meniscus thus provides a shape corresponding to the predetermined optical profile. The optical material is then rapidly cured with actinic radiation, and a desired optical element with high-precision dimensions is formed within the cavities of the moldplate.

Abstract: Injection molding of monolithically integrated optical components is disclosed. In one embodiment, an injection molding system includes a moldplate having an array of specially designed cavities. In at least one cavity, different types of photo-curable optical materials are injected in an ordered sequence. In a first instance, a lens material is injected into the cavity and subsequently cured to form a predetermined lens element at the base of the cavity. In a second instance, a filter material is injected into the cavity above the already formed lens element. The filter material is also cured, and an optical filter is formed stacked onto the lens element and contained within sidewall of the cavity. In this manner, a complex optical component having an optical filter automatically aligned with, and monolithically integrated into, a lens element is readily formed in a single injection molding process.

Abstract: Servers attached to a data communications network, such as a wavelength division multiplexed network, are made aware of events on the network, such as a protection switch for scheduled maintenance to reduce latency and improve performance, etc. Switching data paths on the data communications network is no longer transparent to the server. A message from the network equipment is received and decoded by a holographic enterprise interface coupled to the server and to a virtual network operation centers. The network equipment reports network switch conditions to the holographic enterprise interface and other connected servers. In response to the network switch conditions, the holographic enterprise interface may automatically reprovision data traffic on the network quickly enough to prevent server timeouts and workload interruptions. The switching is then shown in real time in the virtual network operations center.

Abstract: A virtual network operating center (VNOC) automatically and in real time obtains and validates the configuration of a data communications network, such as a wavelength division multiplexed network. The VNOC acquires network configuration data using SNMP commands and server configuration information from the hardware management console. The VNOC collates this data and validates configuration requirements for working and backup fiber paths, client protocols, data rates, regeneration requirements, and other considerations. Both ends of a network can be automatically provisioned and commissioned from a single location wherein the ends may be separated by 100 kilometers or more.

Abstract: A virtual network operating center and a virtual command interface synchronize events occurring on a wavelength division multiplexed network with processing events in a connected server. Should a disaster or other interruption of the network occur, the virtual command interface synchronizes events which occur on the network and any attached servers or server clusters with a reference clock coupled to the server. An event queue connected to the virtual command interface preserves the order of messages having a time stamp and compares the timestamps with the reference clock coupled to the server which is used to determine data integrity. The queued events may be encoded as XML device call to update the representation of the network or portions thereof in the virtual network operation center.

Abstract: An interface coupled to a virtual network operations center and coupled to a data communications network having at least one optical channel. Equipment on the data communications network is identified by the interface wherein the interface coordinates and correlates communications between the I/O interfaces of a server coupled to the network so that data rates and data protocols are managed properly. The interface receives commands from and transmits commands to the data communications network and translates the commands to be further transmitted and used in the virtual network operations center coupled to the server. The data communications network is represented in a three dimensions virtual world in the virtual network operations center so that events on the network can be represented in real-time in the virtual network operations center.

Abstract: A method and apparatus for transmitting signals from a plurality of input channels over a TDM optical network, where each of the input channels contains an optical data signal and an electrical control signal containing control information relating to the optical data signal.

Abstract: A 3D stereographic projection apparatus comprises an input for receiving stereographic image data that includes sync signals corresponding to image streams in the image data. A digital light projector projects the stereographic image data. A motor driven rotating filter has a marker disposed thereon positioned in the path of the projected stereographic image data. The motor driven rotating filter separately polarizes the image streams in the stereographic image data.

A tach sensor, comprising a light transmitter and detector coupled to the rotating filter, detects the marker and outputs marker signals indicating that the marker is detected.

Abstract: A method and apparatus for initializing an end-to-end link in a fiber optic communications system in which a pair of nodes interconnect a pair of end devices. A first node, upon initializing a device link segment with an end device to which the node is coupled, sends a signal to the other node over a network link segment indicating that the sending node has initialized its device link segment. The first node completes initialization of the end-to-end link upon receiving a signal from the other node over the network link segment indicating that the other node has initialized its device link segment. In an alternative initialization scheme, a node momentarily operates its data channel in a loopback mode to allow its end device to initialize the device link segment in accordance with a predetermined protocol before returning to a transparent mode.
