My name is Isaac Kwame Adusei, born in Ghana - West Africa. I am currently studying at Aalborg University Denmark. ( MSc Intelligent Multimedia )
I came to Florida-USA for an internship program with Southern DataStream Inc. During my stay, 23th June to 6th September 2000, I worked on two major assignments.
Calibration of instruments:
This was done to determine how accurate the measuring instruments are. The main instruments considered are the Ultrasonic proximity sensors, Electric rain gauge, and the shaft encoders.
Ideally, the measured distance (y ft) should be equal to the average reading (x ft) on the CR10. Hence a graph of y against x should be: y = x
From the data collected, a graph of the measured distance y against the average reading x is given by (see graph):
y = ax + b -------------------------- (1)
The equation used to calibrated the sensor and running on the CR10 is given by:
x = mx' + k ------------------------- (2)
Therefore to correct the error, we put equation (2) into (1) to give: y = a(mx' + k) + b.
This was the general equation we used to calibrate the sensors. It is important that the sensors be checked from time to time to see if they work correctly.
The Palm Pilot Project:
This project is to developed a full Palm Application that will be able to communication with Dataloggers (download and Upload data from and into it ). This therefore entails a full Graphical User Interface (GUI) development and communications programming.
My part of this project was to study the current PC208W software used for the CR10(X) equipment, and to develop a GUI for a Palm Pilot that would serve almost the same purpose as when using the PC208W on a laptop computer. Such application involves the analysis, design and implementation stages. See the Palm Pilot Project.
