A method and system for a concurrent infrared signal, single thread low power protocol comprises transitioning a remote signal during a first fraction of a bit-period and transitioning another remote signal during a later equal fraction of another bit-period. Additionally, the method includes receiving and decoding two remote signals as a single overlapping signal thread. The disclosed system comprises multiple identifying (ID) remote transceiver units, a pet collar for each ID unit and a base unit attached to a mechanical apparatus for controlling access to food and/or a pet door. Wake-up bursts broadcast by the base unit synchronize to the ID units to the base followed by a rest and a subsequent type indicator preamble to the transmission of unique ID codes from the ID units appended by a battery indicator code. A programmable processor and logic in the base enables the mechanical apparatus based on decoding of the ID codes.
