    "concept_summary": "The LED Incapacitator (also called the Incapacitating Flashing Light Apparatus) uses an array of LEDs or laser diodes that are spatially scanned and temporally flashed in a programmed pattern. The combination of rapid temporal flashing and spatial scanning creates a high-irradiance field that, when viewed, can cause nausea, vertigo, or temporary visual impairment. A range-finder measures the distance to the target's eyes, allowing the device to adjust flash parameters for maximum effect while staying within the Maximum Permissible Exposure (MPE) limits.",
