Abstract
In an embodiment, a processor is configured to randomly select one code from a plurality of predefined codes to identify a first code. A transceiver is operatively coupled to the processor. The transceiver is configured to send a signal representing the first code. The transceiver is also configured to receive a signal representing a second code. The processor is configured to determine whether the second code corresponds to the first code or a third code from the plurality of predefined codes. An actuator is operatively coupled to the processor. The actuator is configured to send a first alert in response to the second code corresponding to the first code and representing an object reflecting the signal representing the first code. The actuator is configured to send a second alert in response to the second code corresponding to the third code and representing a different device being within a predefined distance.
