Video coding using temporally coherent dynamic range mapping
A more efficient co-use of dynamic range mapping on the one hand and temporal prediction on the other hand such as, for example, in order to code HDR frame sequences, is achieved by exploiting the concept of weighted prediction in order to transition from the mapping parameter from the reference frame to the currently temporally predicted frame.

Color changing effects with cross-halftone prints on metal
We propose new methods for creating color varying prints with classical cyan, magenta, yellow inks on a metallic substrate. We use a special crossline halftone with optimized surface coverages of the inks to create color prints on a metallic surface whose colors change when rotating the print in-plane under specular reflection. These prints enable viewing on the same metallic print a first image with a first set of colors and upon in-plane rotation, the same image with parts colored with a different set of colors. They also enable viewing a first color image and upon rotation a second independent color image. Applications comprise counterfeit prevention, art, advertisement exhibitions and amusement parks. |

Triggering window conditions by streaming features of an operator graph
In a stream computing application, data may be transmitted between operators using tuples. However, the receiving operator may not evaluate these tuples as they arrive but instead wait to evaluate a group of tuples—i.e., a window. A window is typically triggered when a buffer associated with the receiving operator reaches a maximum window size or when a predetermined time period has expired. Additionally, a window may be triggered by a monitoring a tuple rate—i.e., the rate at which the operator receives the tuples. If the tuple rate exceeds or falls below a threshold, a window may be triggered. Further, the number of exceptions, or the rate at which an operator throws exceptions, may be monitored. If either of these parameters satisfies a threshold, a window may be triggered, thereby instructing an operator to evaluate the tuples contained within the window. |

Multi-host processing
A packet processor provides for rule matching of packets in a network architecture. The packet processor includes a lookup cluster complex having a number of lookup engines and respective on-chip memory units. The on-chip memory stores rules for matching against packet data.

As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found. The lookup front-end further processes the response message and provides a corresponding response to the host. |

Method for controlling flood broadcasts in a wireless mesh network
Computer networks with multiple nodes are often required to deliver packets to all nodes in the network, commonly referred to as “flooding.” Flooding is used to deliver multicast and broadcast packets generated by application, network and other layers of the networking stack. Flooding can be done very reliably but less efficiently via node to node “unicast” transmissions, or very efficiently but less reliably via “broadcast” transmissions. In order to balance reliability with efficiency, this invention defines a threshold for the number of neighboring nodes as seen by a given node prior to a flooding operation to determine whether data should be unicast or broadcast. Below that threshold, unicast is used; at or above that threshold, broadcast is used. The invention also incorporates knowledge of nodes seen in turn by neighbor nodes as part of this decision. |

Faster synchronization time and better master selection based on dynamic accuracy information in a network of IEEE 1588 clocks
A method and system are provided for synchronizing local clocks more quickly in a telecommunication network using IEEE 1588. A network element that receives timing signals from one or more possible parent clocks considers a measure of the reliability of the timing signals contained in Announce messages from the parent clock or clocks. The clock uses this reliability information in selecting one of the possible parent clock or clocks to use as the actual parent clock. Once the selection is made, the clock adjusts the filtering characteristics applied to timing signals received from the selected parent clock. The adjustments reflect how confident the parent clock is as to how stable the timing information, it provides has become. If the indication of reliability contained in Announce messages received from the parent clock indicates that the timing information is not very reliable, then a high filter bandwidth is used in filtering the timing signals. If the indication of reliability contained in Announce messages indicates that the timing information is reliable, such as by crossing a threshold, then the clock shifts to a normal low bandwidth filtering. By using reliability information in the Announce messages, clocks can better make selections as to which parent clock to use, and can use the reliability information to more quickly synchronize themselves with a grandmaster clock. |

Multi-mode feed network for antenna array
A dual-mode feed network for an antenna array or combination antenna is provided. Two transmission line structures propagate signals according to two different electromagnetic propagation modes, such as TE, TM, TEM and quasi TEM modes. The two transmission line structures are operatively coupled to different components of the antenna array. One transmission line structure may be a stripline or microstrip, and the other transmission line structure may be a waveguide such as a Substrate Integrated Waveguide. Both transmission line structures may branch to reach multiple elements of the antenna array. The transmission lines may share common features, for example by embedding the stripline within the waveguide. |
