2. Project and Personal Overview Target: Patients in ICU suffering from dry eyes require artificial tear at regular intervals Target: Patients in ICU suffering from dry eyes require artificial tear at regular intervals A device which can be easily positioned around the eye socket and will release drops in a dispersed manner at regular time intervals A device which can be easily positioned around the eye socket and will release drops in a dispersed manner at regular time intervals Personal Task : Personal Task : – Device a circuit which will allow the user to control the time intervals for delivery – Research various ways to establish a link between the circuit and the delivery component along with the other members – Calibrate different values of the circuit to make the control user friendly – Model the control component so that it can be directly used by the user

3. Acheivements and Goals Acheivements : The principle behind the circuit has been designed and tested Using any timer chip in astable mode of operation and using a potentiometer to control the interval of delivery Information on electronic injectors for engines and electronic valves are gathered - Clippard Information on electronic injectors for engines and electronic valves are gathered - Clippard –The electronic valve mechanism can be either charge induced or through on and off mode. Goals : Calibrate different values for potentiometers and resistors to make it user friendly. Goals : Calibrate different values for potentiometers and resistors to make it user friendly. The model should be built around the circuit and needs to be sturdy The model should be built around the circuit and needs to be sturdy –Practical building problems like linking the potentiometer to the knob Milestone: 2/1/05 – Decipher and order parts Milestone: 2/1/05 – Decipher and order parts –3/1/05 – working circuit and valve- Calibrated –3/15/05 – fully developed control and link
