Methods and apparatus for reducing interference in a heterogeneous network
Certain aspects relate to methods and apparatus for reducing interference in a heterogeneous network. Certain aspects relate to methods and apparatus for delinking downlink and uplink resource partitioning in a heterogeneous network. In aspects, the delinking is accomplished by reliably delivering uplink grant to a UE, e.g., pico UE in a pico CRE region, without using downlink Almost Blank Subframe (ABS) resources in which an interfering cell limits transmission to reduce interference to other victim cells. In techniques, instead of using the regular PDCCH sent in downlink ABS resources for uplink grant transmission, the uplink grant is sent on another more reliable downlink control channel using resources configured to avoid interference with transmissions from an interfering base station. In techniques, the DL grant is sent on PDCCH in non-downlink ABS resources, but the UE employs enhanced UE capabilities (e.g., interference cancellation) to process the received control information. |

The device may also identify content that preceded (or follows) the foraged content. Thus, a user who tunes-in just at the end of an exciting sporting event can capture one of the following commercials, identify the preceding program, and download same for later viewing. In other aspects, a cell phone can be used as a “second screen,” through which a user can interact with ambient content—such as reviewing electronic program guide data, or enjoying interactive television features. A great variety of other functions and arrangements are also detailed. |

Error concealment techniques in video decoding
Error concealment techniques for video decoding are described. For example, a video decoder after finding a corrupted picture in a bit stream, finds a suitable neighbor for the corrupted picture. For example, the video decoder favors pictures with the same parity as the corrupted picture and considers picture order count and picture corruption in choosing a neighbor.

The modification of syntax elements can depend on the particular video decoder implementation. For example, in a software-only multithreaded video decoder, a task graph is modified, while in a system utilizing video acceleration, syntax elements for reference lists are modified. |

Decoupled packet and data processing rates in switch devices
Continuing to integrate more aggregate bandwidth and higher radix into switch devices is an economic imperative because it creates value both for the supplier and customer in large data center environments which are an increasingly important part of the marketplace. While new silicon processes continue to shrink transistor and other chip feature dimensions, process technology cannot be relied upon as a key driver of power reduction.

Managing information technology resources using metadata tags
A resource manager is tasked with monitoring and managing information technology (IT) resources in a virtual environment. The IT resources are assigned tags that correspond to conditions that alert the resource manager when to begin actively managing the IT resource.

Method for managing logical connections in a network of distributed stations, as well as a network station
The invention relates to the technical field of domestic networks. A domestic network based on the present UPnp-Standard allows AV connections to be set up between two network subscriber stations—Network connections such as these are set up and managed under the control of a network station which is in the form of a control point. In this case, the UPnP-Standard allows the network station which is the form of a control point to log off the network after setting up an AV connection, and thus to be inactive while the AV connection that has been set up is in existence. This results in the problem that an AV connection which has been set up unnecessarily remains in existence even after the desired AV data stream has been transmitted, so that further connection requests for such stations must be answered with a rejection. The invention solves this problem in that it provides additional monitoring means in the network subscriber stations which determine whether the connection has remained unused for a specific time. If yes, a signaling request is sent to all the network subscriber stations. If the connection partner station does not then respond, the connection which has been set up can likewise be added autonomously by the requesting station. |

Contact element and contact arrangement with front protection and method of producing the latter
The present invention relates to an electric contact element that has at least one crimping strap which is configured and arranged to reach around the outer circumference of an electric conductor, at least in sections, at least in a fully crimped state of the contact element. Furthermore, the invention relates to an electric contact arrangement that has at least one electric conductor and at least one contact element that has at least one crimping strap which is crimped, at least in sections, around an outer circumference of the conductor. Finally, the invention relates to a method of producing an electric contact arrangement, at least one crimping strap of a contact element being crimped, at least in sections, around an electric conductor. In order to seal an interior of the contact arrangement as simply and effectively as possible and with long-term stability against the penetration of corrosive media, provision is made according to the invention such that at least one front protection strap of the contact element is aligned running, at least in sections, transversely to the at least one crimping strap and rests against the latter, a front section of the electric conductor being covered, at least in sections, by the at least one front protection strap. |

Crimp terminal and electric wire with crimp terminal
A crimp terminal includes an F-type crimp portion and a C-type crimp portion. The F-type crimp portion has first and second barrel tabs, preferably with an identical length, for crimping a tip end of a complex stranded wire. The F-type crimp portion is adapted to have distal ends of the first and second barrel tabs put together and pushed into the tip end of the complex stranded wire to be crimped. The C-type crimp portion has a third barrel tab for crimping the complex stranded wire. The third barrel tab is wound in a C-form on an outer periphery of the complex stranded wire to be crimped. The arrangement provides a crimp terminal and an electric wire with crimp terminal, that prevents or reduces increases in retained resistance at a crimp portion, and can also prevent an electric wire from slipping out of a crimp terminal. |

Steerable high-power microwave antennas
A steerable, high-power microwave antenna includes: a forward-traveling, leaky-wave feed antenna; a trans-reflecting conical-sectional reflector disposed spaced-apart and above said leaky-wave feed antenna and having a conical surface facing said leaky-wave feed antenna and formed of a plurality of electrical conductors held in parallel order in a grill; and a twist-reflector pivotally mounted opposite and spaced-apart from said conical surface of said trans-reflecting conical-sectional reflector. The twist-reflector is adapted to receive microwave energy reflected to it from said conical surface of said trans-reflecting conical-sectional reflector and to rotate the polarization of said microwave energy and reflect said microwave energy back to said trans-reflecting conical-sectional reflector for passing through said trans-reflecting conical-sectional reflector and forming a narrow, pencil-like beam of high energy radiation in polarized form extending outward from said conical surface of said trans-reflecting conical-sectional reflector. |
