  • Publication number: 20190369682
    Abstract: A method, a device, and an integrated circuit utilizes a temperature restricted mode. The method includes determining a temperature of the device. When the temperature is below a first threshold, the method includes enabling a first mode comprising select network operations. When the temperature is above a brick threshold, the method includes enabling a second mode comprising disabling the select network operations. When the temperature is above the first threshold and below the brick threshold, the method includes enabling a third mode comprising modifying at least one of the select network operations.

  • Publication number: 20190373515
    Abstract: A device, system, and method improve a call setup time. The method is performed at a device configured to establish first and second network connections where the second network performs circuit switched voice calls. The method includes receiving a call input to perform a call and determining whether the device is registered with a first feature to perform the call based on an Internet Protocol (IP). When the device is registered with the first feature, the method includes determining whether timeouts for attempting previous IP calls is greater than a threshold. When the timeouts are at least the threshold, the method includes deregistering from the first feature and performing a circuit switched fallback (CSFB) procedure including a handover from the first network to the second network. The method includes performing the call as a circuit switched call.

  • Patent number: 10368235
    Abstract: Activation or update of a subscriber identity module (SIM) via a roaming cellular wireless network by a mobile device includes the mobile device: determining a country of origin associated with a mobile network operator (MNO) for the SIM, determining a current geographic location of the mobile device, and when the current geographic location of the mobile device does not correspond to the country of origin for the MNO associated with the SIM of the eUICC, presenting an option to activate or update the SIM over a local roaming cellular wireless network. When the option is accepted, the mobile device enables a cellular data roaming capability for the mobile device, activates or updates the SIM via the local roaming cellular wireless network, and, after the SIM is activated or updated, disables the cellular data roaming capability for the mobile device.

  • Patent number: 9019880
    Abstract: Certain aspects of the disclosure relate generally to uplink flow control of wireless devices for mitigation of overload issues. A user equipment (UE) may reduce an average transmit power for the uplink channel based on whether an overload metric (e.g., temperature metric) exceeds a threshold value. The UE may perform duty cycling for an uplink control channel when an overactive uplink control channel is a dominating factor in a thermal issue. The UE may further reduce a maximum power transmit limit (MTPL) for one or more uplink channels, such as physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH).

  • Patent number: 7702641
    Abstract: The embodiments of the present invention provide a method for comparing file tree descriptions and generating a sequenced log of changes that transform an old file tree to a new file tree. According to one embodiment, the inputs to this comparator are two tree-structured descriptions called file tree indices, and the outputs are a sequence of file tree operations that can transform the old tree to the current tree. According to another embodiment, the comparator has two top level steps, where at step one it recursively goes through the old file tree index and compares each folder along with its children with that of the corresponding file tree generating a raw operation log, and at step two after the recursion is done, the comparator processes the raw operation log and optimizes certain sets of operations by transforming them into single operations.

  • Patent number: 7165248
    Abstract: The embodiments of the present invention provide a method for resolving conflicting changes encountered when reconciling parallel user changes to two synchronized trees of folders and files. According to one embodiment, these conflicts are presented to the user as an interface that requires an indication from the user to the winner of the conflict. According to another embodiment, since certain conflicts cannot be resolved independently, they have to be combined and presented to the user as a single conflict. According to yet another embodiment, after the user has indicated which operations are the winners of all or some of the conflicts, the winning operations are applied to the file tree with which they are in conflict.

  • Patent number: 7085779
    Abstract: Methods and systems are provided for reconciling any changes that have occurred in two file trees since they were last synchronized. A reconciler takes as input two logs of the changes made in the respective file trees. The first log resides on a client computing device, and the second log resides on a server computing device. The reconciler outputs two sets of changes that need to be applied to the respective file trees in order to synchronize them. The reconciler detects and outputs a list of changes that conflict with each other.

  • Patent number: 5655058
    Abstract: A method for segmenting audio data, comprising speech from a plurality of individual speakers, according to speaker is provided. The method comprises providing individual HMMs for each individual speaker, each individual HMM including at least one state, and constructing a speaker network HMM by connecting the individual HMMs in parallel. The audio data is then divided into segments by determining a most likely sequence of states through the speaker network HMM, each of the segments being associated with one of the individual HMMs. Afterward, the speaker of each of the segments is identified. The segmented data may be used to form an index into the audio data according to speaker.

  • Patent number: 5606643
    Abstract: A processor controlled system for correlating an electronic index according to speaker for audio data being recorded in real time. The system includes a source of training data for each of the plurality of individual speakers and audio input system for providing real time audio data including speech for the individual speakers. The audio data is converted into spectral feature data by an audio processor, and is simultaneously recorded on a storage medium by a recording device. A system processor accepts the training data to create individual speaker models, which are combined in parallel to form a speaker network. The system processor then accepts the spectral feature data of the audio data and, using the speaker network, determines segments in the audio data corresponding to each speaker.
