Abstract
The present disclosure is directed to methods and systems for providing information about a target based on pulse widths. The information can be provided in a formatted output signal which uses a pulse width protocol to code information by varying amplitudes and widths of successive pulses in an output signal pulse train portion. The method includes detecting a first feature of the target and in response to detecting the first feature, generating an output signal pulse train portion comprising two or more pulses with at least two of the pulses having different amplitudes and each of the two or more pulses having a width corresponding to a logic value. The widths of the two or more pulses in the output signal pulse train portion can be measured in response to the detected first feature reaching a first amplitude threshold, whereby the widths can correspond to different logic values.
