    Abstract: 本計劃致力於執行前端生理訊號的量測、訊號濾波與訊號傳輸安全,目的有三:(1) 生理訊號量測與傳輸:發展並實現前端生理訊號無線量測的解決方案,本計畫將同時處理照護機構(或醫院)最需要的體溫計與血壓計量測訊號,並結合無線射頻辨識 (RFID) 技術以無線的方式傳送到手持式裝置(例如智慧型手機) (2) 訊號品質改善:設計針對心電圖訊號中的前端濾波器提供最佳化的實現(realization) 結構,最佳化的對象係指實現濾波器的有限精準度微處理器及A/D和D/A轉換器,在本項目中,我們已發展一套法則,使得在有限精準度(有限字元長度)的濾波器實現下,有最好的強健性,使得心電圖的濾波訊號得到進一步的改善。 (3) 訊號傳輸時的資訊安全:結合對稱式加密演算法與公開金鑰加密演算法的優點,設計一混合式加密演算機制,並予以實現,以保護受照護者的個人隱私。

    This project is aiming at the measurements and quality improvements of the physiological signals, and they can be divided into three parts: (1) Measurements and Transmissions: We will provide a solution for developing and implementing the wireless transmission of the front-end measured physiological signals via smart phones. (2) Quality improvements of the measured signals: For the need of ECG signal filtering in the other sub-projects, we will design an optimal filter realization subject to finite precision implementations (i.e. finite word length (FWL) implementations of A/D and D/A converters, and register length of a CPU). A stability criterion is derived to enhance the robustness of the filter as well as to improve the quality of the ECG signals. (3) Data protection during transmission: We will design a hybrid algorithm that combines the advantages of symmetric encryption and public key encryption (asymmetric) algorithms to protect the patients’ privacy.
