Systems and methods for communication between devices using a duty cycle of a signal while a device maintains operation responsive to the duty cycle are disclosed. A device receives a signal comprising a duty cycle within a time interval, the duty cycle comprising a plurality of portions and each of the plurality of portions comprising a duration of the duty cycle within the time interval. The device performs an operation responsive to the duty cycle and, in response to a detection of an instruction identified by at least one portion of the duty cycle, performs a function based on the instruction while maintaining the operation responsive to the duty cycle. The device performs operations responsive to duty cycles within time intervals of succeeding signals and performs functions based on instructions from the succeeding signals while maintaining the operation responsive to the duty cycles.
