Abstract: An electronic device and method for power management in an electronic device is provided. In an embodiment, the electronic device includes the functionality of a personal digital assistant, wireless email paging and a camera with a flash that is operated via self-contained power supply in the form of a battery. The device also includes a supervisor circuit which causes the device to enter sleep mode, or disables the device, or certain features of the device, if the battery level falls below a certain threshold. A method in accordance with an embodiment performs, in response to a request to fire the flash, a pre-flash test which is selected so as to not trip the supervisor circuit. The battery level is examined before the pre-flash test and examined as a consequence of performing the pre-flash test, if a change in the battery level as so examined meets certain criterion, then the full flash is not permitted to proceed. If the battery level does not meet the criterion, the full flash is permitted to proceed.

Abstract: A mobile wireless communications device includes a housing an antenna, and radio frequency (RF) circuitry. A transceiver is connected to the antenna and a processor is operative with the RF circuitry. The transceiver includes an In-phase and Quadrature (I/Q) Modulation and Power Amplification circuit having an In-phase (I) circuit with a modulator mixer and power amplifier circuit. A Quadrature (Q) circuit includes a modulator mixer and power amplifier circuit. A power combiner receives the separately amplified In-phase and Quadrature signals and sums and outputs the signals as a combined I and Q signal. The I and Q circuits are isolated from the combined I and Q signal to enhance antenna matching and transmitted radiated power (TRP) and reduce harmonic emission from the power amplification circuits.

Abstract: For context based compression techniques, for example Context Based YK compression, a method and system for grouping contexts from a given context model together to create a new context model that has fewer contexts, but retains acceptable compression gains compared to the context model with more contexts is provided. According to an exemplary embodiment a set of files that are correlated to the file to be compressed (hereafter called training files) are read to determine, for an initial context model, the empirical statistics of contexts and symbols. In some embodiments, this includes determining the estimated joint and conditional probabilities of the various contexts and symbols (or blocks of symbols). The initial context model is then reduced to a desired number of contexts, for example, by applying a grouping function g to the original set of contexts to obtain a new and smaller set of contexts.
Abstract: A communications system may include at least one mobile wireless communications device, and a wireless communications network for sending text messages thereto. More particularly, the at least one mobile wireless communications device may include a wireless transceiver and a controller for cooperating therewith for receiving text messages from the wireless communications network. It may further include a headset output connected to the controller. The controller may be for switching between a normal message mode and an audio message mode based upon a connection between the headset output and a headset. Moreover, when in the audio message mode, the controller may output at least one audio message including speech generated from at least one of the received text messages via the headset output.

Abstract: An improved system and method for managing data on a handheld electronic device includes a server that periodically pushes data to a particular handheld electronic device, with the data being stored on the handheld electronic device by way of a routine running in the background whereby such reception and storage is generally transparent to a user. The data can be any type of data and may be data that is desired by the user or that fits a profile or preference of the user. The profile can, for instance, be predetermined and/or can be customized by the user and/or can reflect a preference of the user. The data pushed to the handheld electronic device can also be related in some fashion to a geographic disposition of the handheld electronic device. Such pushing of data and storage is managed by a routine running in the background of the handheld electronic device. The routine enables current data to be maintained on the handheld electronic device for ready access by a user.

Abstract: A system and method manages configuration data within a hardware component of a device to support hardware component changes during development or manufacture of the device. A Standardized Virtual Part (SVP) file is formed as a binary file and includes a SVP header that comprises metadata of one of at least schema version, revision numbers, part numbers, creator and description. The SVP file also includes hardware configuration data and a SVP trailer that includes error checking data for data authentication. The SVP file is loaded onto the device during development or manufacture for configuring the hardware component.
Abstract: A handheld electronic device useful for wireless communication has a keyboard including a plurality of externally accessible keys, of which at least a portion have multiple letters associated therewith. The keys can be disabled (i.e. the keyboard can be locked) to prevent accidental actuation thereof by using the navigation tool which has a depressible rolling member. Thus, for example, depression of the rolling member twice in succession or pressing and holding the rolling member down temporarily enables the keyboard lock. The lock can be disabled simply by depressing the rolling member and at least one other key.

Abstract: Apparatus, and an associated method, for providing routing information to a mobile node operable in a radio communication system. The routing information is used by the mobile node to address data messages that are to be communicated to a relay host, or other, device. The routing information that is provided to the mobile node includes a plurality of separate routing sequences. Different ones of the routing sequences are used by the mobile node, depending upon at what location that the mobile node is positioned when the data message is sent. A registration server is used by which to create the routing information, responsive to indications of a home network associated with the mobile node and a current location of the mobile node.

Abstract: Standard word lists that are often used for such operations as predictive text, spell checking, and word completion are based on general linguistic data that might not accurately reflect actual text usage patterns of particular users. Systems and methods of building and using a custom word list for use in text operations on an electronic device are provided. A collection of text items associated with a user of the electronic device is scanned to identify words in the text items. A weighting is then assigned to each identified word, and the words and corresponding weightings are stored.

Abstract: The present invention provides a system and method of modifying policy settings in a network having a plurality of subscriber devices. An embodiment includes a plurality of base stations, each capable of wirelessly transmitting across a geographic region and a server. A cell-phone, capable of roaming between regions, is operable to establish a wireless link with the base stations and through the base stations, with the server. The network contains a communication policy determining from which other communication devices a subscriber device can receive voice calls. The communication policy is updated, by the server, based on requests from the subscriber devices. Once a request is received from a subscriber device, the determination whether to update the communication policy can be based on a record of rejections respective to the caller requested to be blocked.
