Abstract: A single-wire bus (SuBUS) slave circuit is provided. The SuBUS slave circuit is coupled to a SuBUS bridge circuit via a SuBUS and can be configured to perform a slave task that may block communication on the SuBUS. Notably, the SuBUS slave circuit may not be equipped with an accurate timing reference source that can determine a precise timing for terminating the slave task and unblock the SuBUS. Instead, the SuBUS slave circuit is configured to terminate the slave task and unblock the SuBUS based on a self-determined slave free-running-oscillator count derived from a start-of-sequence training sequence that precedes any SuBUS telegram of a predefined SuBUS operation, even though the SuBUS operation is totally unrelated to the slave task. As such, it may be possible to eliminate the accurate timing reference source from the SuBUS slave circuit, thus helping to reduce cost and current drain in the SuBUS slave circuit.

Abstract: A method for safely capturing an engine RPM threshold in a spark-ignition internal combustion engine which may exceed the maximum safe unloaded RPM for that engine. Typical engines having a safe RPM high speed redline when coupled to a load, and a reduced RPM redline when decoupled and unloaded, can be set to activate ancillary equipment at a high redline, engine loaded RPM by deriving and processing data from the engine at a low, unloaded reduced RPM speed. The method requires operator reference to an existing OEM or after-market tachometer which enables the user to set a low RPM reference point while the engine is unloaded and running at a slow RPM. Raw data from the latter low RPM reference point selected by a user is safely captured to form a raw threshold while the engine is operating unloaded, and a higher RPM operating threshold is calculated and set from the raw threshold. The higher RPM operating threshold may exceed the maximum safe unloaded RPM for said engine.
