Abstract
An intelligent tracking system generally includes one or more tracking devices, some of which may be passive tracking devices. Each passive tracking device includes one or more transceivers and is energized by an energizing signal. Some of these passive tracking devices may operate in a first communication mode or a second communication mode based on the energizing signal. Some tracking devices may include encryption modules or authentication modules. Some of these devices may incorporate a bulk acoustic wave oscillator.
Claims32
An intelligent tracking system comprising:
- one or more passive tracking devices, wherein each passive tracking device includes one or more transceivers and is energized by an electromagnetic frequency, and wherein in response to being energized each passive tracking device transmits a short message;
- an exciter that emits the electromagnetic frequency that energizes the one or more passive tracking devices;
- and
- a tracker that receives short messages from the one or more passive tracking devices and confirms the presence of the one or more passive tracking devices in a vicinity of the tracker based on the received messages.
