  • Patent number: 10057380
    Abstract: Techniques are described for providing users of client devices with coordinated access to Information and/or functionality of multiple types, such as by using multiple types of connections to multiple information services of distinct types that exchange context information related to activities of the users and/or clients. The client devices can be, for example, wireless devices with multiple distinct modes (e.g., voice and data modes) for different types of connections with different types of servers (e.g., voice servers and data servers). In some situations, coordination between different servers allows multiple distinct interaction sessions of different types with different servers to remain synchronized or otherwise coordinated over time as the user performs interactions via the different sessions. This abstract is provided to comply with rules requiring an abstract, and is not intended to be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 10056992
    Abstract: Methods and systems are provided for dynamical calibration of phase signals and/or amplitudes in a telecommunication system. Calibration of phases is a necessary measure to ensure proper phasing and, as a result, emission of correct beamforming patterns. Without correct phasing (and emission of correct beamforming patterns), performance of a telecommunication network may suffer and user satisfaction may decrease. However, calibration provides a period of time where service is not provided and should not be done too often as it will decrease service provided and, likely, satisfaction of service received if there are frequent periods of outages. By utilizing specific telecommunication metrics, such as temperature, performance, or error vector magnitude, necessary calibrations may be identified and evaluated such that a determination regarding an optimal calibration time is made to balance providing service and a period of service outage.

    Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.
