Mobile location devices and methods
First Claim
1. A user portable, mobile location device comprising geographical location circuitry to provide device geographical location information, power supply circuitry to supply power to the geographical location circuitry, motion detection circuitry to detect motion of the user portable device and control circuitry to control activation/deactivation of the geographical location circuitry, wherein the activation of the geographical location circuitry increases the power supplied by the power supply circuitry to the geographical location circuitry, wherein the control circuitry is arranged to control the activation/deactivation of the geographical location circuitry to provide device geographical location information according to whether motion of the mobile location device is detected by the motion detection circuitry, and wherein the control circuitry is arranged to monitor device motion detected by the motion detection circuitry over successive time periods and control the operation of the geographical location circuitry in response to whether device motion has been detected over one, or a combination of more than one successive, time period.
