(a whole lot of then and goes):
The system starts with the bio monitor; this device utilizes an IR sensor to monitor the minute changes of oxygen levels in your blood. This differential is then amplified using a filtering/amplification circuit based on a dual LM358 op amp and fed into the atmel-based microcontroller. Your galvanic skin response (how sweaty you are) is also gauged by approximating your skins resistance and fed into the controller. The module knows when to start reading data utilizing a Q-prox touch sensor, which is based on a users capacitance. Once the readings are stored they are transferred using a Xbee radio device to a base station hooked onto a pc. The pc uses an application written in java to digest the data then outputs commands to a serial port. The port is hooked to a FTDI serial converter that outputs serial data to a hex inverter. This signal then goes to a Power LinkII serial to X-10 converter, which translates the serial into X-10 protocol and sends the message out over the A/C power lines. Theses signals are passed to a Switch LinkRX which then adjusts the light levels.
