  • Method and receiver for estimating the channel impulse response using a constant modulus interference removal iteration
    Patent number: 7672412
    Abstract: A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation.

  • Message send queue reordering based on priority
    Patent number: 7673018
    Abstract: A method and system for communicating serialized data provides a mechanism for ordering the data in response to a priority. In an embodiment, a server sending the data uses the priority to order the data in a message send queue for sending the data to a requesting device. The server may comprise a gateway and the second device a wireless device communicating with the gateway. The wireless device may send a priority indication in association with a request for the data to facilitate the ordering.

  • Apparatus and method for input of ideographic korean syllables from reduced keyboard
    Patent number: 7671765
    Abstract: Systems and methods for input of text symbols into an electronic device comprising a reduced keyboard having keys representing a plurality of characters are disclosed. Possible symbol variants are identified based on character inputs received from the reduced keyboard. Each identified symbol variant is grouped into one of a plurality of groups of symbol variants, each group having an associated priority, according to a type of the symbol variant. Within at least one of the groups, the symbol variants are ranked in decreasing order of frequencies of use of the symbol variants. A list of symbol variants comprising the plurality of groups of symbol variants in order of decreasing priority is then displayed, and an input symbol is selected from the list of symbol variants. The symbol variants of the at least one of the groups of symbol variants are thereby sorted by both priority and frequency of use.

  • Method and system for labelling unlabeled data records in nodes of a self-organizing map for use in training a classifier for data classification in customer relationship management systems
    Patent number: 7672915
    Abstract: The described embodiments relate to methods and systems for data classification using a self-organizing map. Certain embodiments relate to a method of labeling data for training a classifier, comprising: obtaining data, the data comprising labeled data and unlabeled data; generating a self-organizing map of the data; and a labeling at least some of the unlabeled data based on proximity of the unlabeled data to labeled data within the self-organizing map to generate self-labeled data. The method may include training a classifier based on the labeled and self-labeled data. Other embodiments relate to systems and computer readable media configured to perform, or allow performance of, the method embodiments.

  • Method and apparatus for dynamic session placeholder for message collection user interface
    Patent number: 7672663
    Abstract: A method and apparatus for representing a conversation of related messages is provided. In a message collection user interface for displaying messages sent and received by a communications device, a dynamic session placeholder is used for a respective conversation of related messages. The message collection user interface is displayed including any dynamic session placeholders in the list of messages. As messages from the conversation are occasioned, the dynamic session placeholder is updated. When the message collection is displayed, it is displayed in accordance with the updated session placeholder.

  • Methods And Apparatus For Maintaining Permissions For Client/Server Processing In A Communication Device
    Publication number: 20100050187
    Abstract: A communication device has memory for storing a client application module, a server application module, and an operating system module which are executable by one or more processors. The client application module submits a request and, in response, the server application module causes the request to be processed with use of the operating system module. Prior to processing, an interface module causes one or more client process handles of a client stack of the client application module to be provided in a current process base of the operating system module. Thus, for the request, the operating system module checks one or more permission settings associated with the one or more client process handles as well as one or more permission settings associated with the one or more server process handles.

  • DATA-CAPABLE NETWORK PRIORITIZATION WITH REJECT CODE HANDLING
    Publication number: 20100048208
    Abstract: Reject code handling is utilized for a more time-efficient selection of data-capable networks. One illustrative method for use in selecting a wireless communication network for communications involves the steps of causing a request for data connectivity to be transmitted through a first wireless network; reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a non-critical error is received in response to the request for data connectivity through the first wireless network; and attempting to select a second wireless network for communications without reattempting the request for data connectivity through the first wireless network one or more times if a reject code comprising a critical error is received in response to the request for data connectivity through the first wireless network.

  • Multifunctional Keyboard For A Mobile Communication Device And Method Of Operating The Same
    Publication number: 20100048261
    Abstract: An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.

  • SYSTEM AND METHOD FOR PROCESSING EXTENSIBLE MARKUP LANGUAGE (XML) DOCUMENTS
    Publication number: 20100050072
    Abstract: Systems and methods for processing documents are disclosed. Documents received at a data server are transcoded using locally stored or generated code books. Code books for transcoded documents received at a wireless mobile communication device are either retrieved from a memory on the device or requested from a data server. In response to a code book request, a data server retrieves a requested code book from a local memory or generates the requested code book and returns the requested code book to a requester. A wireless mobile communication device may also generate and transcode XML documents using a locally stored code book, a locally generated code book, or a code book received in response to a code book request.
