TEAM MEMBER CONTRIBUTION
Fiona
Management: Fiona is in charge of taking care of all the project documents and make sure they are turned in on time. In addition, she is in charge of getting the Human Subject approval and applying in for the BMEidea Stipend.
Technical: Fiona has been written codes for Accelerometer testing in Matlab and Labview. She will also be responsible for making the PCB board for entire circuit of the project.
Yu
Yu Shao has maintained an overall picture of the project, and broken it down into individual tasks and assigned them to each team member. He has also worked closely with Michael to test the individual components, such as microcontroller, accelerometer, voltage regulator, switch transistor, vibrator, buzzer, LED, RF transmitter, and RF receiver. Each component has its own testing criteria and boundaries (determined by the team). They ensured that each component met our requirements. Recently, they have been studying the accelerometer analog signal to find ways to diminish the noise and to distinguish the characteristics of reading motion and rest.
Yu will work with Michael to program for the microcontroller interfaced with all the components. They will then test all the entire system whether each component can function properly when the components are all together. Finally, they will test to ensure functionality, durability, ease of use, and power consumption of the entire system.
Mike
Michael has worked with Yu in testing individual components and analyzing the signal output from the accelerometer. Their current focus is to reliably identify those signals generated by reading motion. He is helping determine what filtering technique will be best suited for our purposes.
Michael is also responsible for the proofreading of all the team’s documents. Anything written by other team members is sent to him for editing including the design proposal, all progress reports, and the final design document.
Nick
Nick’s responsibilities begin in the wireless zone between the pen and receiver microcontroller. Nick is also working on the interface between the receiver microcontroller and computer. This mainly involves writing the microcontroller program to take in Radio Frequency (RF) signal, which Yu did, and send that signal via USB to the computer. At the other end he must write a java program to receive this data and turn it into useful data that will allow a user to track their data over time and see trends. Essentially his responsibilities lie in the receiving side of the RF, including the microcontroller and java program.
