Systems and methods for multivariate stroke detection

This is a wrist-worn device that uses light to measure how much blood is flowing under your skin. It also has a tiny heater and a temperature sensor. By heating your skin and then re-measuring blood flow, it aims to spot unusual changes in your body, specifically focusing on a wrist application.

Why it matters: No fundamental technological shifts have occurred in the two years since filing that significantly alter the feasibility of this device. The core challenge remains the accuracy and regulatory approval for detecting complex medical events from peripheral measurements.

Status: Under examinationA pending application. It has not been granted, and it has not been abandoned.
How hard to build: SpecializedMiniaturized sensors, custom heating, specialized algorithms.
