  • Patent number: 7929535
    Abstract: One feature provides a method for encoding geolocation information into a next-generation internet protocol (IP) address, such as IPv6, to facilitate distribution of geolocation information among networked devices. A request for an IP address assignment is received from a network device. The geographical location for the network device is obtained. An IP address is assigned or generated that includes the geographical location. The assigned IP address is then provided to the network device. By encoding the geolocation information of a first network device into the IP address assigned to the first network device, other network devices are able to readily obtain the geographical location of the first network device. This method propagates geolocation information for network devices as part of the IP address, thus avoiding the need for separate geolocation distribution messaging. As the network device moves, its IP address is changed to update its geographical location information.

  • Publication number: 20110059748
    Abstract: Implementations relate to systems and methods for localized notification that provide localized information to one or more mobile devices in a wireless communication system that are located in one or more geographical regions. The wireless communication system includes a localized notification server that responds to geographically-targeted broadcast requests and localized service or information requests. The localized notification server localizes components of the wireless communication system into sets of localized components that provide wireless communication service to mobile devices in the specific geographical regions. In response to a request to broadcast to a target geographical region, the localized notification server identifies a set of localized components associated with the target geographical region. The localized notification server then broadcasts information to mobile devices actively serviced by the set of localized components.

  • Publication number: 20110022952
    Abstract: Determination of proximity measurements indicative of respective intended inputs are disclosed. User inputs are received, where each user input is one of a predefined plurality of inputs that each map to multiple characters in a language. Rates of user selections of candidates decoded from the user inputs into the language are received, where each of the candidates includes one or more characters in the language. User inputs for the candidates having low rates of selection as non-selected user inputs are identified. User inputs for the candidates having high rates of selection as intended inputs are identified. The intended user inputs to the non-selected user inputs are compared to identify one or more misspelled input and intended input pairs. A proximity measurement for each misspelled input and intended input pair is determined based on a ratio of the number of times corresponding candidates for the misspelled input were not selected to the number of times the misspelled input was entered.

  • Patent number: 7844251
    Abstract: Some embodiments provide a method, system, and apparatus for transparently backing-up information from a mobile device to distributed devices having storage capabilities. As the mobile device comes within communication range of one or more of the trusted partner devices, information from the mobile device is backed up, in segments or portions, on the one or more distributed partner devices. Information backed-up in one partner device may be transferred to another partner device for storage. A centralized master server may also maintain a list of the locations (e.g., partner devices) where backup information is maintained for the mobile device. When requested to do so by a user, the centralized server can retrieve and consolidate the backup information for the mobile device.

  • Patent number: 7810030
    Abstract: Fault-tolerant systems and methods to process and correct input errors are disclosed. Original inputs can be received, each original input being defined as mapping to multiple characters in a language, each original input having one or more associated proximity measurements. Original inputs that have proximity measurements with one or more non-zero probabilities for respective intended inputs are identified as potentially incorrect original inputs. Each of the potentially incorrect original inputs is expanded to the respective intended inputs, and each of the original inputs and each of the respective intended inputs are converted to characters in the language, each of the conversions being a combination of the converted original inputs and/or the respective intended inputs. Likelihoods of conversions of the original inputs and the respective intended inputs to the characters based in part on the proximity measurements are determined, and most likely conversions are identified for presentation.

  • Publication number: 20090009397
    Abstract: Location of a wireless communication device is determined by a combination of geolocation and a detection of augmenting data such as acceleration and/or speed over time measurements. A last known terrestrial navigation fix is established based on reliable terrestrial navigation or GPS data. A zone of valid location fixes based on the last known terrestrial navigation fix and an output of a rate detection circuit can be established. A weighted average is taken of using independent location measurement and detected location using last known reliable position plus change in position by integrating position changes over time.
