CytoSensor system integration and design is driven by requirements generated by
the need to complete biological experiment operations. The system is used for toxin-based
detection which will identify and quantify unknown input toxins by using a biosensor
based on a living fish chromatophore. The system consists of 3 main parts: biosensor,
data acquisition and data interpretation.
This thesis is focused on data acquisition. Acquisition, in this case, is via a color
camera since the cells have an easily measurable visual output. The major initial task
is to select the hardware specifications that satisfy user requirements. Components are
obtained from different vendors. The understanding of each component is, therefore,
very important to maximize the system performance and compatibility.
The second major task is to design the software interface and components to
manage the data acquisition. This can be separated into 2 parts. The first part is
acquisition management and control. The second part is the human interface. This
thesis focuses on the human interface.
The human interface is the part that communicates between the user and the
system. The system will send the system status to the user. The user will then direct
the system through the operation. Operators may not be familiar with complicated
computerized systems. A user-friendly interface is important to reduce mistakes and
to facilitate the operation. The goal of this design is to direct the user from a single
look at the interface. The interface should therefore contain all the useful and necessary
information.
The design of the user interface begins with gathering the necessary information
and making a decision about which information is important to deliver to the user. A
clean, tidy and informative user interface will lead to efficient operation. The design
methodology is to group the same information within the same area and be consistent.
Machine operation is very important, as well. In order to reduce the confusion in
system operation, the machine operating protocol is designed to be very similar to the
traditional protocol.
Design of the machine operation is through interactions with the user. Sending
user information to the machine will be handled by the system management program.
By simulating the user scenario, each state change will lead to changing of the state of
the machine, as well. The scenario is implemented in a state-like diagram. This state
diagram must be implemented carefully in order to be able to handle all the cases and
exceptions.
The last and most important part is putting all the components together and
testing the system. All possible scenarios and features listed before designing will be
tested at this point. The last test is to run actual experiments with the system. After all
the tests are satisfied, the system is delivered to the user. At this time, the user might
give more feedback on the system.
In conclusion, the overall goal of designing this system is not only to make the system
for this specific application. However, the goal is to design a general application that
will be able to apply to different sensor application. By changing the core management
and hardware, the software can easily fit another sensor application. / Graduation date: 2003
