Abstract
A sensor is used to detect movement of a mobile device. For example, data received from an accelerometer may be averaged together and compared to a threshold value. If the average of the data is greater than a threshold value, the mobile device may be assumed to be moving. This information may be used to control the frequency of data collection by, for example, a GPS receiver in order to maximize utility and minimize power use.
