Intermediation system and method for enhanced rendering of data pages
An intermediary system is disposed along a communication path between a user device, such as a Web-enabled mobile phone, and a content server. The user device sends a request, such as an HTTP GET request, for a data page at the content server. The data page may be, for example, the hypertext markup language (HTML) code of a Web page. The intermediary receives the request and determines whether the requested data page includes a data reference, such as a uniform resource locator (URL) of an embedded image in the Web page. If the requested page includes a data reference, the intermediary creates a preload instruction and sends the preload instruction to the user device in a response to the request for the data page. The preload instruction instructs the user device to load the referenced data. The preload instruction may be a hidden frame. |

System and method for efficient horizontal maximum distance separable raid
In recent years, researchers have found that some XOR erasure codes lead to higher performance and better throughput in fault-tolerant distributed data storage applications. However, little consideration has been given to the advantages of parallel processing or hardware implementations taking advantage of the emergence of multi-core processors.

EEO is the fastest and most efficient double disk failure recovering algorithm in RAID-6, at the cost of only two more parity symbols. In practice, it is very useful for application where high decoding throughput is desired. |

Generation of a set of pre-filters from a set of event subscriptions to more efficiently select events of interest
A method, system and computer program product for achieving a balance between pre-filter efficiency and pre-filter throughput. Event subscriptions are obtained for a given event consumer. The event subscriptions define the events to be routed to this event consumer. Pre-filters of varying complexity and filtering power are constructed based on these event subscriptions. A balance between pre-filter efficiency and pre-filter throughput may be achieved by selecting the best pre-filter out of these constructed pre-filters to filter events to its associated event consumer. The best pre-filter is selected by comparing a complexity threshold (e.g., a limit for the number of atomic Boolean expressions in a pre-filter) with the actual complexity (e.g., the actual number of atomic Boolean expressions) for each constructed pre-filter and selecting the most complex pre-filter without exceeding the threshold. |

Concurrency control in a file system shared by application hosts
A manager program for managing virtual machines includes a process which receives a notification message indicating an occurrence of an event affecting a data storage unit in a data storage system that supports a shared file system.

Case acquisition for incremental Case-Based Reasoning system
A method and system are presented that simplify acquisition of cases for an incremental Case-Based Reasoning system. Case acquisition closely follows the normal problem-solving process and cases are automatically created in a form suitable for the CBR runtime. The method and system rely on the fact that the CBR runtime is already capable of taking the input data and constructing a case in a form that corresponds to the library cases. The problem-solving mode is transformed into the case-acquisition mode by replacing the ‘choose next action’ step in the incremental CBR algorithm by a step that generates a set of all applicable actions given the current content of the session case and the model. From these the user can choose an action that corresponds to an action from the real-world case description. This is repeated as part of the incremental CBR loop until a full case has been acquired. |

Lock-and-key consumer billing data protection for telemarketing
A “lock-and-key” consumer billing data protection capability is provided to telemarketing systems which are based upon previously-acquired consumer lists. The lists contain only partial billing information for each consumer, which is insufficient to access the consumer's account. Thus, at the time a telemarketer employing this capability communicates with a consumer to offer them a product or service, the telemarketer, the seller and any entity hired to perform billing operations for such consumer purchases all remain “locked” out from accessing the consumer's account. When the consumer wishes to authorize the purchase of an offered product or service, the consumer must “reach into their wallet” to provide the “key” to their account, which is the missing billing information not acquired from the third-party list provider. |

Interface device, communications system, non-volatile storage device, communication mode switching method and integrated circuit
A host device and a slave device are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode. |

Master/slave transceiver power back-off
An apparatuses and methods of setting power back-off of a master transceiver and a slave transceiver is disclosed. One example of a method includes the master transceiver determining a master power back-off, and the slave transceiver determining a slave power back-off based on signals received from the master transceiver, and based on the master power back-off. One example of an apparatus includes a master transceiver and slave transceiver system. The slave transceiver is connected to the master transceiver through a cable. The master transceiver includes means for determining a master power back-off. The slave transceiver includes means for determining a slave power back-off based on signals received from the master transceiver, and based on the master power back-off. |

Generation of HARQ-ACK information and power control of HARQ-ACK signals in TDD systems with downlink of carrier aggregation
Methods and apparatus are provided for a User Equipment (UE) configured to have multiple cells in a DownLink (DL) of a Time Division Duplex (TDD) communication system so as to determine a power of an acknowledgement signal that the UE transmits in a control channel and to determine a number of acknowledgement information bits that the UE multiplexes with data information bits in a data channel. A transmission power of the control signal is determined based on DL Assignment Index (DAI) Information Elements (IEs) in DL Scheduling Assignments (SAs) that the UE detects through multiple transmission time intervals and through the multiple configured DL cells. The number of acknowledgement information bits in the data channel is determined based on a DAI IE of an UpLink (UL) SA associated with the transmission of the data channel. |

Quality of service securing method and apparatus
A quality of service (QoS) securing apparatus and method using a communication protocol is provided. The QoS securing method is performed by a reception side that is receiving data from a transmission side. The method includes generating information about a changed communication environment according to a change in a communication environment of the reception side, and transmitting the information to the transmission side. An exchange of information about a communication environment using the communication protocol between the reception side and the transmission side can inform the transmission side about resources of the reception side, link characteristics, characteristics of a link on a transmission path, etc., thereby securing a QoS of data communication between the reception side and the transmission side. |
