Abstract:
Methods, program products, and systems for location filtering using mobile country code (MCC) is described. A mobile device can determine its geographic location using locations of access points of a wireless communications network to which the mobile device is connected. The mobile device can wirelessly receive identifiers of one or more access points of the wireless communications network and a current MCC through a cellular network. The mobile device can identify a polygon that is a bounding box of a geographic area that corresponds to the current MCC. The mobile device can select a set of access point locations from a location database using the received identifiers, where the access point locations are inside the identified polygon. The mobile device can determine a current location of the mobile device based on an average location of the selected set of access point locations.
Abstract:
Customizing a device based on space and time (e.g., a geographic position of the device at a particular time) is disclosed. In one aspect, geographic position data of a device is obtained. Temporal data that is related to the geographic position data is obtained. An operational mode is selected based on the geographic position data and the temporal data for activation on the device. In some implementations, the operational mode identifies a communication medium.
Abstract:
A device coupled with a magnetometer and an angular rate sensor can determine a heading of the device using magnetometer data. When the device receives a notification that the magnetometer data may be inaccurate, the device can determine the heading of the device using angular rate data. When the device determines that the magnetometer data are accurate, the device can resume determining the heading of the device using the magnetometer data.
Abstract:
The embodiments described relate to techniques and systems for utilizing a portable electronic device to monitor, process, present and manage data captured by a series of sensors and location awareness technologies to provide a context aware map and navigation application. The context aware map application offers a user interface including visual and audio input and output, and provides several map modes that can change based upon context determined by data captured by a series of sensors and location awareness technologies.
