I. Hardware Integration Sensor Description Sensor Figure Sensor Name galvanic skin response (GSR) Pulse and Oxygen in Blood (SPO 2) Description Skin conductance, also known as galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. Pulse oximetry a noninvasive method of indicating the arterial oxygen saturation of functional hemoglobin. Body Position The Patient Position Sensor (Accelerometer) monitors five different patient positions (standing/sitting, supine, prone, left and right. ) Glucometer is a medical device for determining the approximate concentration of glucose in the blood. The meter displays the level in mg/dl or mmol/l. Body temperature depends upon the place in the body at which the measurement is made, and the time of day and level of activity of the person. Different parts of the body have different temperatures Page 6

III. System Implementation Pebble Smart Watch Android Arduino Pebble Original Plan: Two Slave devices cannot be paired Implementation: Using Android as a bridge for transmission Page 15

III. System Implementation Pebble Smart Watch Message format Example: //content of message: “connected” const uint 8_t connected. Msg[30]={0 x 00, 0 x 1 a, 0 x 0 b, 0 x. B 8, 0 x 01, 0 x 00, 0 x 09, 0 x 43, 0 x 6 f, 0 x 6 e, 0 x 6 e , 0 x 65, 0 x 63, 0 x 74, 0 x 65, 0 x 64 , 0 x 0 d , 0 x. FF, 0 x. FF , 0 x. FF, 0 x. FF}; Yellow part: These 6 numbers are fixed for every message. Green part: This hex number is the number of the char included in this message. Blue part: The sequence of hex number is obtained by transform the content of the message into hex format. Red part: The rest of the message packet is filled with “ 0 x. FF”, in order to reach 30 hex numbers in each message packet. Page 16

Conclusion 1) Arduino: Excellent choice for conducting this project. § Completed Library and easy language § Plug and play Feature Great potential for development of medical system § Low cost § Good extensibility Page 18

Conclusion 2) Bluetooth: Meet the system requirement § Communication range § Low cost Convenient for future development § compatibility Page 19

3) Java: Conclusion not an appropriate language for serial communication § Input stream reading: Number of read byte: 5 Number of read byte: 25 Number of read byte: 30 Number of read byte: 13 Number of read byte: 17 Number of read byte: 22 Number of read byte: 8 § Byte hex Better to combine with other language such as C. § Good in development of interface and multimedia Page 20
