Abstract

This paper presents the concepts, design, and algorithms for a wearable swallow monitoring system. Swallow monitoring can be used for assessing a person's overall food and drink intake habits as well as other swallow related disorders. The system works based on the key observation that a person's otherwise continuous breathing process is interrupted by a short apnea when she or he swallows as a part of food intake process. Using a wearable chest-belt, we detect swallows by detecting apneas extracted from breathing signal captured by the chest-belt. A matched filter based template matching framework is developed for swallow detection. A number of matched filter template design, both static and iterative, are developed for high-accuracy swallow detection.

摘要

本文介绍了一种可穿戴式吞咽监测系统的概念、设计和算法。吞咽监测可用于评估一个人的整体饮食摄入习惯以及其他与吞咽相关的疾病。该系统基于这样一个关键观察结果：当一个人在进食过程中吞咽时，其原本持续的呼吸过程会被短暂的呼吸暂停打断。通过使用可穿戴式胸带，我们通过检测从胸带捕获的呼吸信号中提取的呼吸暂停来检测吞咽。为吞咽检测开发了一种基于匹配滤波器的模板匹配框架。为了实现高精度的吞咽检测，还开发了许多匹配滤波器模板设计，包括静态和迭代的设计。
