Abstract: A system is disclosed for messaging between wireless mobile terminals operating on wireless carrier networks and networked computers. The mobile terminals and computers include client applications for communicating messages to one another using push-to-talk modality. A server, located on a packet network outside the wireless carrier networks, forwards messages between the mobile terminals and the computers. The messages consist of text or streaming voice. The server can also include gateways for forwarding messages from the mobile terminals and computers to external email and instant messaging (IM) users. By placing the server outside wireless carrier networks and using conventional packet network protocols such as the Internet protocol (IP), the system provides seamless inter-carrier push-to-talk and/or instant messaging between mobile terminal, networked computers, and users of third-party email and IM services.

An antenna may also be carried by the portable housing and connected to the satellite positioning signal receiver. Further, at least one electrically conductive director element may be carried by the portable housing in spaced apart relation from the antenna and inductively coupled thereto for directing a beam pattern thereof.

Abstract: A portable electronic device capable of assuming an open configuration and a closed configuration comprises a primary light sensor and a secondary light sensor. When the portable electronic device is in the open configuration, a light sensor signal is selected from the primary light sensor, and when the portable electronic device is in the closed configuration, a light sensor signal is selected from the secondary light sensor.

Abstract: A joint demodulation filter for reducing co-channel interference between a desired signal and a co-channel interfering signal may include an input receiving samples of the desired signal and the co-channel interfering signal, a Viterbi decoder, and a first signal path between the input and the Viterbi decoder comprising a first filter. The joint demodulation filter may further include a second signal path between the input and the Viterbi decoder and comprising a linear finite impulse response (FIR) modeler for generating a channel impulse response estimate for the co-channel interfering signal. Additionally, a third signal path may be between the input and the Viterbi decoder and include a whitened matched filter for generating a channel impulse response estimate for the desired signal.

Abstract: A system and method for propagating device settings to a data communications client from a host on a mobile device, the system having at least one host application adapted to operate on the mobile device host and further adapted to change device settings on the mobile device; a notification means adapted to notify the data communications client of device settings changes on the mobile device; a mode setting at the data communications client, the mode setting adapted to indicate whether client applications on the data communications client should use device settings from the host; and a client settings application adapted to receive a notification from the notification means and change device settings for the client applications if the mode setting indicates the client applications should use device settings from the host.

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.

Abstract: A device and a method of responding to a received interrupt event received by a communication device is provided. The method comprises accessing data associated with a calendar application and/or a location application to determine a current state of availability of a user of the device using data; determining whether a response action is to be sent in response to the event when the device is note available; and sending the response action. The device incorporates modules to perform the method.

Abstract: A mobile computing device, including a main body, a processor and associated memory housed within the main body, a display screen housed within the main body and responsive to signals from the processor, an optical sensor fixed to the main body for capturing successive images and providing image signals representative of the captured images to the processor, and a navigation module associated with the processor for determining, based on the image signals, a relative movement between the main body and a reference surface and moving a pointer on the display screen based on the determined relative movement.

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.

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.

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.

Abstract: For a cell-phone or PDA, the rows of key-caps include respective light-strips, which pick up light from respective LEDs surface-mounted on the PCB. The light-strips are sandwiched between the key-caps and the key-switch actuators (whereby the light-strips move with the keys when the keys are depressed). Sockets for receiving the key-caps are co-molded to the light-strips. Sockets are provided in the resilient webs of the keys for receiving under-blocks co-molded to the light-strips.

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.
