Tracking memory mapping to prevent packers from evading the scanning of dynamically created code
To detect possible malicious code that is unpacked at runtime before it is executed, antivirus software requires that any dynamically created code be scanned before it can be executed by a host computer system. This requirement may be enforced by requiring memory pages to be either executable or writable, but not both. Before changing from writable but not executable to executable but not writable, the page is scanned for malicious code. To prevent packers from evading this scanning, a countermeasure tracks the memory mapping in the host system to enforce consistency in the protection settings for all memory spaces that are mapped to the same physical memory page. |

Gateway for connecting networks of different types and system for charging fees for communication between networks of different types
A gateway for connecting networks of different types is designed to connect a first network and a second network that uses a signal format and a protocol that are different from those of the first network. The gateway comprises a conversion section, a detection section, and a network-connecting section. When communication is performed between a terminal connected to the first network and a terminal connected to the second network, the conversion section converts a signal used in the first network to a signal to be used in the second network, and a signal used in the second network to a signal to be used in the first network. The detection section detects conversion-process information containing at least one of the time spent to convert the signal and the amount of data converted. The network-connecting section is connected to at least one of the first and second networks and transmits the conversion-process information to a fee-charging system of the first network or a fee-charging system of the second network. |

Parameterized recursive network architecture with topological addressing
A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities. |

Network acceleration techniques
Splintered offloading techniques with receive batch processing are described for network acceleration. Such techniques offload specific functionality to a NIC while maintaining the bulk of the protocol processing in the host operating system (“OS”). The resulting protocol implementation allows the application to bypass the protocol processing of the received data. Such can be accomplished this by moving data from the NIC directly to the application through direct memory access (“DMA”) and batch processing the receive headers in the host OS when the host OS is interrupted to perform other work. Batch processing receive headers allows the data path to be separated from the control path. Unlike operating system bypass, however, the operating system still fully manages the network resource and has relevant feedback about traffic and flows. Embodiments of the present disclosure can therefore address the challenges of networks with extreme bandwidth delay products (BWDP). |

Dynamic isolation of shared resources
Shared resources can be isolated such that abuse of the resource by one user does not significantly affect the use of that resource by another user. A combination of access and flow control can be used, wherein a control gateway or other such component sits along a path between the user and the resource, such that the user obtains connections or access to the resource through the gateway. In this way, the gateway can control aspects such as the number of concurrent threads or channels granted to a user, as well as any delay in providing these threads or channels to the resource. A closed feedback loop can provide real-time information such that adjustments can be made dynamically, preventing abuse by users while also preventing the resource allocations from being underutilized. |

Hosted system for enabling enterprises to build and operate online communities
A system that enables enterprises to design, create integrate and operate online communities. The system operates as an on-demand hosted platform (software-as-a-service) that provides a secure and reliable architecture on which enterprises can safely and securely develop, execute and manage their online communities. The platform combines a wide range of web-based participation technologies (e.g., blogs, wikis, discussion groups, social networking, podcasts, RSS, tagging, photos, videos, mapping, and the like). Any content can have attributes that make it appear as any type of content. With this uniform content architecture, all user-generated content is treated as a post (or, more generally, a submission), and there is no need for a participant to author multiple entries for separate uses. Preferably, all content created or otherwise associated with a particular author is intrinsically tied or “linked” to the author via the author's profile. Thus, at each point of participation, the content is associated with the individual, which allows the system to build and maintain a rich “living” profile for each community member. Using this approach, the system can build and enable querying of so-called “social aggregations,” which are data sets that describe a relationship among one or more author attributes and one or more content attributes. |

Controlling markets during a stop loss trigger
A system mitigates the effects of a market spike caused by the triggering and election of conditional orders in an automated matching system. The system monitors trading that takes place as a result of the cascading triggering of conditional orders. When an order is executed beyond a predetermined price threshold, an instrument may be flagged, allowing matching to take place only at or within the predetermined price threshold. Orders within the price threshold are matched at the price threshold against orders beyond the price threshold, in order to dampen any instantaneous damaging effects of the price spike. The system may adjust the price threshold when market appropriate, allowing the order flow to bring the market back to whatever is the true price level. The system mitigates price fluctuations that are purely conditional order cascade driven, but allows the market to continuously trade in controlled price and time intervals to ensure that a true market move can still occur and not have price control mechanisms hinder trade matching and true price discovery. |

Method and system for dynamically terminating wireless and wireline calls between carriers
A third party tandem provider that intercepts and routes voice and data traffic between telecommunications carriers, e.g., wireless carriers, local exchange carriers, and long distance carriers, by dynamically determining the actual terminating switch for a call using a plurality of proprietary databases versus terminating calls merely based on the switch associated with the terminating telephone number. The tandem services provider Service Control Point (SCP) is arranged to maintain a carrier unit's status in a resident database or secure such information per call from the terminating carrier's database. When a call is placed to a telephone number associated with a carrier connected to the tandem, the tandem platform Service Switching Point (SSP) queries the SCP for availability and routing instructions. In response, the SCP accesses its database and/or the terminating carrier's database to determine the status of the unit. If the unit is available, the SCP sends the SSP the unit's current service address (e.g., IP address, telephone number, location routing number) to route the call to the switching location currently serving the subscriber unit. If the unit is unavailable, the SCP sends the SSP the information to route the call to the home switch associated with the called unit for announcement, voice mail, or other treatment. The terminating carrier thus avoids the internal routing inefficiencies of re-directing the call within its network. |

Low power ultra wideband transceiver
Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power. |

Video packet shaping for video telephony
The disclosure relates to techniques for video packet shaping for video telephony (VT). The techniques can be used to prioritize audio packets to reduce audio delay. Channel conditions, excessive video content, or both can cause delays in audio transmission.

The video packet may consume an excessive number of MAC RLP packets, resulting in delays between successive audio packets. The size of each video packet is adjusted so that audio packets are prioritized for transmission without substantial delay. The video packet size may be controlled based on channel conditions. The audio can be conveyed without substantial delay, even though the video may suffer from delay due to channel conditions. Although video may be compromised by channel conditions, video packet shaping ensures that the VT parties are able to smoothly carry on verbal conversation. |

Techniques are provided to support fast frequency hopping with a code division multiplexed (CDM) pilot in a multi-carrier communication system (e.g., an OFDMA system).

This allows the receiver to individually identify and recover multiple wideband pilots transmitted concurrently by multiple transmitters. For a time division multiplexed (TDM)/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in bursts. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot, albeit at a low transmit power level. Any frequency hopping rate may be supported without impacting pilot overhead. |

Radio transmitting apparatus and method for transmitting OFDM signals from different antennas according to the degree of multiplexing
The degree of multiplexing of a code division multiplexed signal transmitted by subcarriers is selected on a subcarrier-by-subcarrier basis.

In the receiving side MAC layer timestamping approach, the MPDU structure is changed by adding an extra timestamping field. When a MPDU packet is generated, a captured receiving timestamp is written into the MPDU's timestamp field. The MPDU packet is then forwarded from the PHY to the MAC layer of the wireless sensor node. In the MAC layer, the receiving timestamp is further processed and inserted into a corresponding field of the time synchronization message, which is in turn transmitted to a Time Synchronization module. In the sending side MAC layer timestamping approach, the sending timestamp is captured immediately before the time synchronization message is written into TxFIFO. |

Leakage current compensation for high voltage transformers
A method and system for measuring and compensating for a leakage current in a high voltage transformer. Such a method and/or system include the use of a primary winding and a secondary winding, which can be provided on a core of a soft-magnetic material. A current transformer can be placed about the leads to both the terminals of the primary winding. The current transformer can be utilized to reliably measure the leakage current flowing from the secondary winding to the primary winding through one or more amplifiers to a ground terminal. The leakage current flows back to the transformer secondary winding through a low-side current sense resistor. The total current monitor signal can be generated by the low-side current sense resistor and the leakage current measured by the current transformer is vector-subtracted from the total current monitor signal. The result is a current monitor signal fully representative of the high voltage transformer's actual load current. |

Integrated upstream spoiler and particle filter in a hard-disk drive (HDD)
Approaches for integrating an upstream spoiler with a particle filter in a hard-disk drive (HDD). According to an approach, a single part may comprise an upstream spoiler and an opening. The single part has a structure which enables an airborne particle filter to be positioned over or within the opening. The airborne particle filter, which covers the opening, has a curvature that follows the curvature of a shroud. When the upstream spoiler diverts a flow of air, which circulates within the enclosure when the magnetic-recording disk is rotating, from the magnetic-recording head, the upstream spoiler creates an area of relatively greater pressure. Air in the area of greater pressure flows through the airborne particle filter to an area of relatively lesser pressure, thereby removing airborne particles within the enclosure of the HDD. Alternately, the airborne particle filter may be positioned within slits present in the shroud and the upstream spoiler. |
