Techniques for preparing a user device for use in a location having limited network access include replacing data in the device cache prior to the user device reaching the location. A length of time until cached data expires, a length of time used to replace the cached data, and a length of time for the user device to reach the location are determined. Portions of the cached data that will expire while the user device is within the location are replaced. The time at which the data is replaced is based on the length of time used to replace the data and the length of time for the user device to reach the location. While the user device is in the location, functions that transmit large quantities of data may instead be replaced with more efficient data types or queued for later execution after the user device exits the location.

A method of monitoring human activity includes monitoring accelerations using an inertial sensor disposed at one of a plurality of locations on a human body, wherein at least one of the plurality of locations is not a foot location. A plurality of steps are counted based on the accelerations. A gait characteristic of the plurality of steps is determined. The characteristic is used to determine a stride length. At least one of a distance traveled and a speed of travel are determined based on the stride length.
