Abstract
The Ambient Cognitive‑Clearance System (ACCS v4.0) is a non‑contact, zero‑wearable, room‑scale device designed to support cognitive health by enhancing sleep quality, autonomic stability, and glymphatic clearance — the brain’s natural waste‑removal system.
Unlike wearable neuromodulation, ultrasound helmets, or extracorporeal systems, ACCS v4.0 requires no physical contact, no user compliance, and no medical infrastructure.
The system uses contactless sensing (radar, thermal, acoustic) to detect sleep stages and respiration, and delivers low‑intensity, air‑coupled acoustic/ultrasonic pulses, 40 Hz diffuse light, sub‑audible gamma acoustics, and micro‑airflow cues — all synchronized to the user’s natural physiology.
This document provides full engineering specifications, regulatory considerations, consumer framing, and a lab‑ready build & test protocol so any qualified research team can prototype and evaluate the concept.
