Abstract
In some embodiments, an apparatus includes a wireless receiver circuit that can receive a wireless signal from a wireless communication device that is (1) separate from the wireless receiver circuit and (2) can encode a first information according to a protocol. The wireless receiver circuit can detect a predefined sequence of changes of a characteristic within the wireless signal to decode, from the wireless signal, a second information mutually exclusive from the first information without decoding the first information. In such embodiments, the wireless receiver circuit can send the second information.
