The present disclosure provides methods, systems, and devices for tracking a mobile device in an indoor area or bounded area. A method for tracking a mobile device includes receiving sensor data from a mobile device and generating a heuristic map based on the sensor data describing a set of possible current locations of the mobile device in the bounded area. The method further includes receiving additional sensor data from the mobile device, and determining a change in position of the mobile device based on the additional sensor data. The method further yet includes updating the heuristic map to disqualify a first possible current location from the set of possible current locations, and outputting the updated set of possible current locations for display on a user interface.

Mobile device localization based on relative received signal strength indicators

Systems and methods are disclosed for performing file backup and restore in a computing system. Certain embodiments provide a communication interface for communicating with a non-volatile memory and a controller configured to determine that a file stored in the non-volatile memory has been modified, identify a chunk of the file that has been modified, determine a new chunk associated with the modified chunk, the new chunk reflecting the modification, generate a separate chunk file including the new chunk and a filename, and storing the chunk file in the non-volatile memory using the communication interface.
