Reduced thickness tracking device
In a tracking device, a crescent-shaped printed circuit board (PCB) partially encircles a battery to minimize thickness of the tracking device. A speaker and a light emitting diode (LED) emit alerts upon command of a control apparatus or in response to a motion or a temperature sensed by a sensor. A local network has one hub for tracking a plurality of tracking devices and a wider area network has multiple hubs for more detailed tracking of the plurality of tracking devices. The wide area network tracks the plurality of tracking devices anywhere and stores data of each tracking device including its last known position and its sensor data.
1. A tracking device comprising:
a first cover, wherein an inside edge of the first cover has a substantially circular cross-section;
a second cover, wherein the second cover is shaped to mate with the first cover;
wherein the first cover and the second cover form a cavity for receiving a battery when mated together;
a printed circuit board having at least one sensor and a transmitter for sending signals including a signal with information for identifying the tracking device, said printed circuit board having a crescent shape that includes a first edge shaped to follow the inside edge of the first cover and a second edge shaped to follow a curvature of the cavity for receiving the battery; and
at least one conductor coupled to the printed circuit board;
wherein the at least one conductor includes a protrusion configured to contact the battery when the battery is positioned within the cavity; and
wherein a non-conductive portion of the first cover or a non-conductive portion of the second cover holds the at least one conductor against the battery while the battery is positioned within the cavity.
