So "Sensors:" → sensors are the component name, but "Sensors:" as a heading is the same as "Detectors|Sensing units|Input devices:", but the user wants to keep the names unchanged. Wait, no. The user says "leave names unchanged". So if "Sensors" is a component's name, then it's a name and should remain. However, in the original text, "Sensors" is part of the section heading. If "Sensors" is a name, then it should be left. But "Sensors" is a common noun. Wait, maybe the user considers the component names like Sensors, Actuators as names, so need to leave them as is? Wait, the instruction says "Leave names unchanged." So if "Sensors" is considered a name (e.g., a proper noun), but in the original text, it's capitalized. Hmm, maybe the user wants to keep the section titles as they are. Wait, the user hasn't specified whether to revise the section titles or not, but the instruction says to revise every word with synonyms. However, they mentioned "Leave names unchanged." So perhaps the component names like Sensors, Actuators are names and should not be revised. Let me read the user's instruction again. That makes more sense
