Abstract
In a tracking device 10, a crescent-shaped PCB 12 partially encircles a battery 15 to minimize thickness of the device 10. A speaker 23 and an LED 24 emit alerts upon command of a control apparatus 37 or in response to motion or temperature sensed by sensor 25. A local network 40 has one hub 41 to tracking devices 33 and a wider area network 45 has multiple hubs for more detailed tracking of devices 33. A wide area network 50 tracks devices anywhere and stores data of each tracking device including its last known position and its sensor data.
