Weekly Progress Reports (see sidebar), the Gantt chart, and this Project Management page should be printed out before meetings with the sponsor and instructor.
All team members should be able to explain all items on the progress report.
Place a "*" at the beginning of the title of the active week Progress Report (see * in sidebar).
Project Objectives
Concisely list and prioritize the project objectives and constraints
High Priority Objectives
· Develop Membrane-Strip-Simulator Module
o Simulator should be able to simulate the fluorescence of the saliva strip membrane to specified light wavelength(s)
o Must be able to fit in the ESE Quant Lateral Flow device
o The ESE Quant will be used as a " gold standard" reference for our simulator performance.
· Build the Test Bed
o The test bed is a prototype of the optical-mechanical system that will serve as the platform for Gaia's hand-held dehydration tester
o The test bed will consist of a UV emitter, a photo-sensor, a filter/lens, relevant circuits, and mounting hardware
o Must be able to quantify a range of light emission intensity and wavelength
o 3D materials can be used, but should resist physical deformation during normal operation
o Fabrication of apparatus to accommodate the simulator
o Durability of platform requires at least 3 years of operation
· Six testing measurements in which our simulator and test bed will be evaluated by:
o Sensitivity
o Repeatability
o Signal to Noise Ratio
o Optical Performance
o Stray Light Performance
o Temperature Stability
· A calibration curve shall be constructed from the testing measurements stated above. Vertical axis: photosensor log intensity; Horizontal axis: LED driver current; Accuracy defined by R^2 fit of linear regression in dynamic range; Precision defined by CV% for inter and intra runs. Each of these tests should be repeated for 3 different LED’s and/or attenuator settings (pin hole, iris or density filters).
Second Priority Objectives
· Incorporate all electrical components of test bed into a single, computer-controlled system
· Inclusion of a standalone microcontroller unit, such as the Arduino
Other Constraints and Issues
· Size
· Materials
· Optical properties
· Configurations and wavelengths
WOW Design Solution
Ask what would their dream design solution would be like. You may not achieve this, but it is good to know what it would be like.
· Adjustable wavelength and intensity of a light source in the simulator. It would allow quicker testing of a range of wavelengths
· Digital output readouts on a standalone display
· Easily reproducible circuit board design
· Interchangeable UV emitter, photo-sensor, and filter on test bed
Risk Reduction Strategy
List areas of risk and strategy that will be used to eliminate risk early in the design process.
· Finding all suitable components and see if they will work and fit together
· Create a physical model of the inside of the ESE Quant in order to test dimension of prototypes of simulator
· Find out all the available information on the ESE Quant device
· Understanding the range of sensors and photodiodes
· Doing optics research to understand how the sensor and filter will work separately and together
Intermediate Milestones
Identifying meaningful intermediate milestones is a critical for effective project management. Together with your sponsor identify such milestones, and specify specific performance requirements you aim to meet at each milestone.
