Distributed malicious software protection in file sharing environments
Automatic file replication and scanning for malware in a sharing environment is based on detection of file system changes. Only one client of the multi-client environment needs to include malware protection software for all clients to benefit. A file replication service for each client monitors a shared directory, and synchronizes files across clients at the file system driver level. When a new file appears in the shared directory of a client system, through this driver, the new file automatically gets replicated. A malware protection component operates by monitoring the directory for new or modified files. File replication causes automatic malware scanning on the client that has protection. When the file has been cleaned and re-written to the directory, the replication service senses that the file has changed and replicates the cleaned file to the other clients. Thus, the replication behavior produces a multiparty file scanning and cleansing protection scheme. |

Interference reduction for multiple signals
The present invention reduces the degradation in performance of one or more radio signals that are co-transmitted with a first radio signal from the same transmitting antenna in the same frequency channel and received by the same antenna due to multipath or other shared interference, where the one or more radio signals can be separated from the first radio signal. All received signals are coupled to the same adaptive array or adaptive filter to reduce multipath or other shared interference of the first radio signal, which reduces multipath and other shared interference in the other radio signals before they are separated and processed by their respective receivers, or the individual radio signals are separated before the first signal enters the adaptive array and coupled to a slave weighting network slaved to the weights of the adaptive array of the first signal to reduce interference in all the signals. |

DC power control for power amplifiers
Some embodiments of the present disclosure relate to transmission techniques that result in power savings relative to previous solutions. These techniques often transmit a signal-of-interest by using two paths, namely, a transmission path (which includes a power amplifier) and a control path. The signal-of-interest is evaluated in “fast-track” fashion on the control path, such that the control path can “tune” a DC supply signal provided to the power amplifier. Thus, when a delayed version of the signal-of-interest is provided over the transmission path to the power amplifier, the DC supply signal provided to the power amplifier helps ensure that the power amplifier has “just enough” DC supply to ensure reliable operation without dissipating excess power. In this way, the techniques disclosed herein help to reduce power consumption in transmitters, thereby potentially helping to extend battery life and reduce undesired heating for users. |

Radio communication system, radio communication apparatus, and radio communication method
Reliability of beam selection by pre-coding is improved. A user terminal 52 selects an optimum beam (beam number ‘b’) in the next frame (t+1) based on the channel estimation value of a received pilot signal and transmits a difference value D (=b−a) between a beam number ‘a’ at the current transmission notified by a radio base station 51 and the selected beam number ‘b’ selected to be transmitted at the next transmission to the radio base station 51 as a feedback signal. The radio base station 51 previously stores the beam number ‘a’ notified at the previous transmission and combines the beam number based on the difference value D received as the received feedback signal and the previously notified beam number ‘a’ to restore the beam number ‘b’ desired by the user terminal 52. Pre-coding processing adapted to the beam number ‘b’ is performed and transmission to the user terminal 52 is executed in a state in which a beam of the appropriate beam number ‘b’ is formed. |

Methods for detecting and classifying signals transmitted over a radio frequency spectrum
A method for classifying a signal is disclosed. The method can be used by a station or stations within a network to classify the signal as non-cooperative (NC) or a target signal. The method performs classification over channels within a frequency spectrum. The percentage of power above a first threshold is computed for a channel. Based on the percentage, a signal is classified as a narrowband signal. If the percentage indicates the absence of a narrowband signal, then a lower second threshold is applied to confirm the absence according to the percentage of power above the second threshold. The signal is classified as a narrowband signal or pre-classified as a wideband signal based on the percentage. Pre-classified wideband signals are classified as a wideband NC signal or target signal using spectrum masks. |

An obstacle region candidate point relating unit assumes that a pixel in an image corresponds to a point on a road surface, and associates pixels between images at two times on the basis of the amount of movement of a vehicle in question, a road plane, and a flow of the image estimated. When a pixel corresponds to a shadow of the vehicle in question or the moving object therearound appearing on the road surface, the ratio of intensities of the pixel values of the spectral images between two images should be approximately the same as the ratio of the spectral characteristics of the sunshine in the sun and the shade. Therefore, when the ratio of intensities is approximately the same as the ratio of the spectral characteristics, the obstacle determining unit does not determine that the pixel in question is a point corresponding to the obstacle. Only when the ratio of intensities is not approximately the same as the ratio of the spectral characteristics, the obstacle determining unit determines that the pixel in question is a point corresponding to the obstacle. |

Scalable image coding and decoding
The invention relates to a scalable video (de)coding method for wireless transmission of high definition television signals. Scalable means that the bitstream contains successively smaller quality refinements and that the bitstream can be truncated. The video images are divided in slices, and each slice is divided in blocks of 8×8 pixels. For each block, an optimal encoding method is chosen. Depending on whether the block is found to contain natural or synthetic image content, transform coding (DCT) or graphic coding is applied. Because the different encoding modes have different properties as regards picture quality, the bitstream format has to enable the encoder to very flexibly choose which bits to send first. The bitstream format in accordance with the invention consists of a multitude of scans (31-34) through the coded data of a series of individual blocks, e.g. a slice. In each scan, the encoder decides whether it will include data for natural blocks (BS1,BS2), for synthetic blocks (BS0,BS1), or both. For the DCT blocks, it can further choose between DC coefficient bits (22) and AC coefficient bits (23). For example, the encoder can choose to first send a few scans of DCT DC bits, then send a few scans of graphics bits and then send some DCT AC bits. The decisions that the encoder makes are signaled to the decoder in the form of flags that precede each block part (e.g. encoded bit plane) and/or plurality of blocks (e.g. a slice). |

System and method for digital image intensity correction
The present invention provides a method and apparatus to enhance the image contrast of a digital image device, while simultaneously compensating for image intensity inhomogeneity, regardless of the source, correcting intensity inhomogeneities, and producing a more uniform image appearance. Also, the image is enhanced through increased contrast, e.g., tissue contrast in a medical image. In the method, the error between the histogram of the spatially-weighted original image and a specified histogram is minimized. The specified histogram may be selected to increase contrast for accentuation, e.g., on localized regions of interest. The weighting is preferably achieved by two-dimensional interpolation of a sparse grid of control points overlaying the image. A sparse grid is used rather than a dense one to compensate for slowly-varying image non-uniformity. Also, sparseness reduces the computational complexity, as the final weight set involves the solution of simultaneous linear equations whose number is the size of the grid. |

Call contention mediation after dropped call
A call contention manager mediates between call contentions that occur when two callers attempt to place a telephone call to one another at approximately the same time. The call contention manager may be implemented in or separate from a mobile switching center. The manager detects a call contention between two calls, and it determines whether the call contention is taking place in a window of time that follows shortly after at least one of the callers was involuntarily dropped from a call. If a call contention occurs within such a call drop window, it is resolved according to a post-drop protocol that enables a connection between the callers. If, however, the call contention occurs outside any call drop window, it is resolved without establishing a connection between the callers, for example by sending one or more of the contending calls to voicemail. |

Techniques herein include systems and methods that extend functionality of transport networks including Transparent Interconnect of Lots of Links (TRILL) networks. Techniques include using a portion of information within transport device address encapsulation headers for purposes other than identifying source and destination device addresses. The system masks a portion of bits in an address header for an address lookup in forwarding tables of a transport network node. The remaining bits in the address field(s) become free bits that can be used for a variety of application purposes, such as flow identifier selection. By using information fields that already exist in encapsulation headers, such techniques provide additional information without increasing packet size or requiring new protocols. Embodiments can combine Equal-cost multi-path routing (ECMP) functionality, Reverse Path Forwarding (RPF) checks, and Time to live (TTL) protection at the same time. |

Method and apparatus for reducing flood traffic in switches
An imporved method and apparatus for making forwarding decisions in a switching device. The invention reduces the flooding of frames to particular network segments connected to the switch. To insure a device sees a frame addressed to it, if a switch does not know what segment a device address is connected to for a unicast frame, the switch typically floods the frame to all segments in the broadcast domain. This invention allows segments to be identified as having a predefined maximum number of device addresses that will be associated with it. When that number of addresses is already in the forwarding table the switch will not flood unicast frames to that segment since no more devices should be connected to that segment. |

Decoder control
A decoder control makes use of controllable transfer gates, which effectively implement selectors, to implement required timing offsets for codes that have particular structure. For instance, such timing offsets are effective for LDPC codes with block off-diagonal structure, for instance, as described in the co-pending application. In some implementations, the memory architecture is formed of cells where each cell includes not only a storage element, by also control logic that combines a select signal and the write versus read signal. By co-locating this control logic in each memory cell, control logic and its associated signal distribution is reduced, thereby reducing circuit area and power consumption. |
