Personal tracking device with low power consumption
First Claim
1. A portable tracking device, comprising(a) a wireless communication module;
- (b) a GPS module;
(c) a radio beacon; and
(d) at least a primary power supplier and a secondary power supplier;
wherein said portable tracking device is either in a standby mode in which said GPS module, wireless communication module, and radio beacon consume substantially no energy or in an operation mode which entails substantially more energy consumption and said wireless communication module, said GPS module and said radio beacon are in connection with a microprocessor having a timer which turns on said tracking device from said standby mode to said operation mode in a predetermined time interval;
wherein said portable tracking device has a first operation configuration and a second operation configuration;
wherein when in said first operation configuration said wireless communication module, said GPS module and said radio beacon are in connection to and powered by neither said primary power supplier nor said secondary power supplier and when in said second operation configuration said wireless communication module, said GPS module and said radio beacon are in connection to and powered by said primary power supplier either simultaneously or at different times; and
wherein said timer is in connection to and powered by said secondary power supplier and is configured to trigger a change of said portable tracking device from said first operation configuration to said second operation configuration in a predetermined time interval.

Abstract
An portable tracking device integrating a mobile phone module (e.g. based on GSM or 3G networks), a GPS module, a radio Beacon and ultrasonic beacon. The tracking device is normally in a hibernated state when the entire device consumes little energy and require no periodically changing or recharging batteries to power the device. It consumes power from the primary battery only when a tracking process is actually taken place. With this portable tracking device on the person who is unable to affirmatively report his or her whereabout, the remote center and/or a search team can communicate the GPS module, radio beacon and ultrasonic beacon of the tracking device via the mobile phone module based on existing wireless communication technologies, such SMS, GPRS, ect, on GSM or 3 G networks, which also serves as a means of initial rough estimation of the tracking device'"'"'s location.

10. A process of tracking a person who cannot communicate his or her location to others, comprising the steps of:
-
(a) associating said person with a portable tracking device within which there is a GPS module, a wireless phone module, a radio beacon, a timer within a microprocessor, a primary power supplier and an optional secondary power supplier; (b) presetting said timer to trigger activation of said device from a standby mode in which said GPS module, wireless phone module, and radio beacon consume no energy into an operation mode in which said wireless phone module is turned on and powered by said primary power supplier; (c) informing a remote center by said wireless communication module that said tracking device is in operation; (d) obtaining information about the location of said tracking device from a phone service provider; (e) turning on said GPS module and determining an area where said person associated with said portable tracking device is located if GPS signal is good; (f) turning on said raid beacon to guide a search team to an areas where said person associated with said portable tracking device is located if GPS signal is poor. - View Dependent Claims (11, 12, 13, 14)
