CoreBluetooth
- Bluetooth 4.0之後就將通訊模式分為高速及低速種類，目前將低速低耗能簡稱為BLE，可以連接一些量測型的感測器類型像：心跳計、血壓…等，這使得iDevice不再是利用MFi認證過的Dock才能與iDevice連接，增加APP型態的多元。 如果想要跟BLE週邊連接，iOS提供了CoreBluetooth framework來與週邊連接，整個程式中分為Discover、Connect、Explore、Interact，下面將會以從連線至BLE讀取到資料為原則來介紹。 -Bluetoo
TIZHENmethod
- 心脏向外泵血引起与心跳同步的身体的震动,产生体震信号,其规律与心率相关,可在脊椎轴上通过敏感的力传感器检测出来.体震信号微弱且易受干扰,针对此特点设计了传感器电路和信号处理电路,说明了检测方法.所获得的原始体震信号先经预处理去除噪声,再应用模极大值算法得到每个心动周期中的峰值点,最后求得心率.采集体震信号时,同步采集一路单通道心电信号作为基准,评价测量的准确性.实验结果表明,基于体震信号的心率测量方法获得了良好的效果.-The heart to pump blood out of the bod
APPLICATION-PROJECT-LIST-1
- Considering ambulatory seizure monitoring, we found that the optical heart rate sensor has several advantages over the standard ECG. The lack of electrodes and wires reduces potential skin irritation, risk of losing signal due to electrodes fal

EMBEDDED-LIST-MASTER
- The MIO sensor emitted the OHR signal at 1 Hz. The method for derivation of this OHR the raw PPG signal was not made public by the manufacturers. Heart rate was extracted offline the ECG data using a MATLAB implementation of Afonso et al. [5].
DIPLOMA-APPLICATION-PROJECT-LIST1
- revolution in this industry is the use of green light reflection photoplethysmography (PPG) which can be measured with a watch worn on the wrist. With PPG, heart rate is detected through measurement of changes in blood volume using either trans

- 这篇应用报告讨论了使用 MSP430FG437 微处理器（MCU）进行非侵入性光体积描记法设计，非侵入性光体积描记法又被称为脉搏血氧仪。脉搏血氧仪由一个外围探头结合 MCU在 LCD 显示屏上显示氧饱和度和脉搏率。在这项应用中，同样的传感器被用于心率监测和脉搏血氧监测。探头被放置在身体的周边地点比如指尖，耳垂或鼻子。探头包括两个发光二极管（LEDs），一个处于可见红光波谱（660nm），另一个处于红外波谱（940nm）。身体的含氧量先通过测量每一频率的光传输通过身体后的强度，再计算这两个强度间的
