Abstract

A wireless tracking device operating in at least two modes to reduce power consumption and extend the operable period of the wireless tracking device. In an active mode, the wireless tracking device samples sensor signals at a higher resolution and may also actively communicate with a remote device via wireless connection. In a hibernation mode, most of the components or modules in the wireless tracking device are shut down to reduce power consumption. The wireless tracking device may switch to the active mode when a predetermine event is detected.
