Encoder quantization architecture for advanced audio coding
An advanced audio coding (AAC) encoder quantization architecture is described. The architecture includes an efficient, low computation complexity approach for estimating scalefactors in which a base scalefactor estimate is adjusted by a delta scalefactor estimate that is based, in part, on global scalefactor adjustments applied to the previously quantized/encoded frame. Using such feedback, the AAC encoder quantization architecture is able to produce scalefactor estimates that are very close to the actual scalefactor applied by the subsequent quantization and encoding process. The architecture further includes a frequency hole avoidance approach that reduces a magnitude of an estimated scalefactor to avoid generating frequency holes in quantized SFBs. The efficient, low computation complexity scalefactor estimation approach combined with the frequency hole avoidance approach allows the described AAC encoder quantization architecture to achieve high audio fidelity, with reduced noise levels, while reducing processing cycles and power consumption by approximately 40%. |

Adaptive filtering for image transform processes
Adaptive filtering techniques are set forth that improve video playback performance. A color similarity metric is computed for source pixels undergoing an image transform operation to determine color values of a target pixel location. The value of the color similarity metric defines what algorithm is used to determine the color values of the target pixel location from the source pixels. While the computation of the color similarity metric introduces additional instructions for each pixel, going against conventional wisdom, enormous performance savings by avoiding unnecessarily complex sets of interpolation instructions where a simpler instruction set suffices, outweighs any such cost from additional instructions. |

The threshold can be chosen such that the probability of a single false detection over the expected life of the mission for which correlation detection is being performed is extremely low. The peak value in the image is determined and a correlation is considered detected when the peak value is greater than the product of the threshold and the Rayleigh parameter. If a detection occurs, the correlation image detector returns the transformation that co-registers the two images. |

Link bundled co-routed VCAT via RSVP message bundling
Multiple RSVP messages are used to separately signal components of co-routed VCAT to enable the separate components to be implemented on different physical fibers of a link bundle. To enable the PATH messages to be handled as a group, the multiple PATH messages are grouped together and sent out in a RSVP bundle message. When a RSVP bundle message containing multiple PATH messages is received at a network element, such as an ENNI, where the route for the PATH messages needs to be expanded, the route is expanded collectively rather than individually. Specifically, the route will first be expanded and this expanded route will be inserted into each individual PATH message. The modified PATH messages with the expanded route will then be passed through the RSVP finite state machine one at a time to enable resources to be reserved for the connections of the VCAT. Thus, a single LSP may be created for each channel, and the channels may be co-routed even where route expansion is required. |

Network-wide flow monitoring in split architecture networks
Flow monitoring tasks are assigned to a set of switches in a split architecture network to optimize network-wide flow monitoring. The assignment maximizes the number of monitored flows and reduces overhead of the flow monitoring. A controller receives an estimated traffic volume for each path in the network. The controller calculates, for all of the switches and all of the paths, sampling fractions that maximize the number of the flows sampled by the switches. In response to a request for setting up a new flow to traverse one of the paths in the network, the controller assigns the new flow to one of the switches that are located on the one of the paths, based on the sampling fraction for the assigned switch and the one of the paths, the bandwidth constraint and the memory constraint. |

Method of reading optical information and method of recording optical information
In a method of recording and reading optical information in a recording medium using holography, a first recording operation is performed for recording optical information in a first recording region in an overlapping manner by allowing a reference beam and a signal beam with data loaded to interfere with each other in the first recording region, the reference beam being angularly multiplexed at predetermined intervals. Furthermore, a second recording operation is performed for recording optical information in a second recording region adjacent to the first recording region in an overlapping manner by allowing the reference beam and the signal beam to interfere with each other in the second recording region, the reference beam being angularly multiplexed between the predetermined intervals. Consequently, optical information can be recorded so as to easily detect and determine a selected reproducing beam, thus increasing the reading efficiency of the optical information. |

Thermally-assisted magnetic recording head capable of reducing the transient protrusion of an antenna
A slider mounted TAMR (Thermal Assisted Magnetic Recording), DFH (Dynamic Flying Height) type read/write head using optical-laser generated surface plasmons in a small antenna to locally heat a magnetic medium, uses the same optical laser at low power to pre-heat the antenna. Maintaining the antenna at this pre-heated temperature, approximately 50% of its highest temperature during write operations, allows the DFH mechanism sufficient time to compensate for the thermal protrusion of the antenna at that lower temperature, so that thermal protrusion transients are significantly reduced when a writing operation occurs and full laser power is applied. The time constant for antenna protrusion is less than the time constant for DFH fly height compensation, so, without pre-heating, the thermal protrusion of the antenna due to absorption of optical radiation cannot be compensated by the DFH effect. |
