  • Publication number: 20150189465
    Abstract: A computer-implemented method for optimizing battery power and data access costs during fetching of data in a mobile device is disclosed. The computer-implemented method includes determining whether the mobile device is connected to a station for charging the battery, determining whether the mobile device is receiving a net positive charge, and determining whether the mobile device is in data communication with a server through a cellular network. The computer-implemented method further includes preventing fetching of data in the mobile device when the mobile device is one of: (1) not connected to the station for charging the battery, (2) connected to the station for charging the battery, yet operating in a manner that draws down the battery, (3) in data communication with the server through a cellular network, or (4) not in data communication with the server through an internet connection.

  • Publication number: 20150186413
    Abstract: A pre-fetching map data system and method identifies a subset of map data to corresponding to one or more points of interest to be displayed on the map. The map data is stored on a remote map database in map data tiles. The pre-fetching map data system identifies those map data tiles that correspond to the one or more points of interest, where the identified pre-fetch map data tiles are sent from the remote database to a client device for cache storage. The number of pre-fetch map data tiles are determined using a tile budget, such as a maximum number of map data tiles that may be stored on the client device or a maximum amount of map data memory that can be consumed on the client device.

  • Publication number: 20150189038
    Abstract: A computer-implemented method and system for pre-fetching remote resource data from a remote mapping system for display on a client computing device is disclosed. Data received at a client device from an online mapping system in response to a query from the client device includes vector and remote resource data. Vector data is rasterized by the client device to depict graphical elements that are easily described by mathematical formulas. Remote resource data includes digital map elements that are not easily described by vectors, but instead, must be relayed to the client device as either bitmaps or references (e.g., URLs) to remote resources that are resolved at the backend or the client device. This remote resource data is prefetched to a client device so that it will be available for subsequent mapping application searches without resolving a corresponding reference to the remote resource data for each search.

  • Publication number: 20150186443
    Abstract: A pre-fetching map data system and method identifies a subset of map data to corresponding to one or more points of interest to be displayed on the map. The map data is stored on a remote map database and in the form of map data tiles bearing version numbers. The pre-fetching map data system identifying those map data tiles that correspond to the subset of map data corresponding to the one or more points of interest, where the identified pre-fetch map data tiles are sent from the remote database to a client device for storing the pre-fetch map data tiles. During pre-fetching the version number of the received map data tiles is examined to determine if a version update for additional map data tiles should be scheduled and executed to update out of date map data on the client device.

The pre-fetching map data system identifies those map data tiles that correspond to the one or more points of interest, where the identified pre-fetch map data tiles are sent from the remote database to a client device for cache storage. The number of pre-fetch map data tiles are determined using a tile budget that is dynamically adjusted in response to changing conditions on a client device.

  • Patent number: 8970632
    Abstract: The present disclosure relates to temporarily rendering a display on a display device using map data stored in a high speed memory of the display device while the display device is waiting to receive updated data from a display device persistent memory or a remote map data database in response to a user initiated request for updated data. The present disclosure also relates to a display device high speed memory management module for managing the contents of a high speed memory.

  • Patent number: 8954092
    Abstract: A computing system extracts, based on one or more electronic messages sent or received by a user of a mobile computing device, travel plan information associated with the user of the mobile computing device. The travel plan information may indicate a destination to which the user is planning to travel. In response to extracting the travel plan information, the computing system may send an instruction to the mobile computing device to cache, in advance of the user arriving at the destination, information associated with the destination. In this way, the mobile computing device may access the information associated with the destination while at the destination, even if the mobile computing device is unable to access the information via a wireless communication channel.

  • Patent number: 8711181
    Abstract: A pre-fetching map data system and method identifies a subset of map data to corresponding to one or more points of interest to be displayed on the map. The map data is stored on a remote map database and in the form of map data tiles. The system identifies those map data tiles that correspond to the subset of map data corresponding to the one or more points of interest, where the identified pre-fetch map data tiles are sent from the remote database to a client device for cache storage. The pre-fetch map data tiles are identified using a variable map tile radius, which when extended from the points of interest defines the map tiles that qualify as pre-fetch map data tiles. The tile radius can be fixed or dynamically adjusted and changes across different map zoom levels.
