A wearable optical sensing arrangement that detects migraine onset by comparing personalized blood pressure measurements against a user-specific reference database.

Patentradars sammanfattning

This invention describes an optical sensing arrangement that illuminates a body part, captures reflected or transmitted light, and extracts health parameters—primarily blood pressure (systolic, diastolic, and pulse pressure)—to detect impending migraine onset. A control unit identifies the person, retrieves their personalized reference parameters from a centralized database, and flags a deviation event when measured values fail a person-specific acceptance criterion. The system supports multi-variate conditional analysis (e.g., conditioning blood pressure thresholds on heart rate), environmental parameter correction, and post-onset medication efficacy monitoring. It is designed for integration into wearable devices such as smartwatches, smart rings, and earpieces.
