  • Patent number: 9225468
    Abstract: Systems and methods for detecting data in a received signal are provided. A signal that represents a set of data symbols is received. Possible bit values for a single data symbol of the set of data symbols are determined based on the received signal. Possible bit values for other data symbols of the set of data symbols are determined based on the possible bit values for the single data symbol. The determining of the possible bit values for the other data symbols includes determining a first value for each bit included in the other data symbols. The first value is determined by combining i) a first soft metric indicating a likelihood of a state of the bit given the received signal, and ii) a second soft metric representing an a priori probability (APP) for the bit. The first soft metric is not based on the APP for the bit.

  • Publication number: 20150347936
    Abstract: A method for partitioning a database includes obtaining business dependency between data in a plurality of tables in the database on the basis of a business process associated with the database; generating, on the basis of the business dependency, a dependency graph describing a dependency relationship between the plurality of tables; cutting the dependency graph into at least two sub-graphs; and vertically partitioning the database into at least two parts corresponding to the at least two sub-graphs respectively.

  • Patent number: 9203796
    Abstract: A messaging system facilitates communication between users through various messaging channels. The messaging system supports multiple communication channels and includes a messaging module that automatically selects one or more of the messaging channels for delivering a message to a recipient of the message using, for example, a set of policy rules or a trained model. The messaging module may also provide, in a user interface for sending and receiving messages, a visual indication of the selected messaging channel to the sender of the message to provide the user with transparency about how the message will be delivered. Additionally, the message may be delivered via multiple messaging channels, where the messaging module may rescind messages from some of the messaging channels upon receiving a reply from the recipient of the message or other confirmation that the recipient has seen the message via one of the communication channels.

  • Publication number: 20150271012
    Abstract: A method uses web servers to promulgate information from one server to another, instead of promulgating the information by the user to each server individually. A first server receives a first request for promulgating web-information from a user, locally promulgates the web-information, and sends a second request to at least one second website server to instruct the second website server to locally promulgate the web-information. The selection of the second server is done according to a preset configuration file which includes a relationship mapping between the first website server and the second website server. The relationship mapping may provide the user information related to the second website server based on the user information related to the first website server. The present disclosure further discloses a communication apparatus and a communication system.

  • Patent number: 9130749
    Abstract: Methods and systems for decoding a data packet using soft-bit retransmission combining are provided herein. A first transmission of the data packet is received and corresponding soft information is generated. The soft information is represented by a first set of bits and a subset of those bits is stored. Subsequently, a second transmission of the data packet is received and corresponding soft information is generated. The soft information corresponding to the second transmission is represented by a second set of bits and combined with the stored subset of soft-bits corresponding to the first transmission to produce a third set of bits. At least a portion of the data packet is decoded based on the third set of bits.

  • Publication number: 20150211760
    Abstract: Systems and methods for providing constant airflow based on direct motor power control and advanced motor system modeling are described. A power and speed of a motor may be determined based on static pressure in the system. A target airflow rate for the system may be obtained, and a target motor power that yields the target airflow rate in the system may be determined based on the determined speed of the motor and the obtained target airflow rate for the system. A determination of whether the determined motor power is approximately equal to the target motor power may be made, and the power of the motor may be adjusted when the motor power is not approximately equal to the target motor power.
