Title: Automated Medical Patient's Evaluation System
Description: The objective of this project would be to develop a touch-screen capability to accomplish the following activity. The doctor would retrieve the patient's name (John Smith) via a list of patients for the day. A split screen would appear with the patient's name at the top of the top screen (see figure 1). On the next line on the top screen would appear the diagnosis heading as shown in the figure. In the bottom screen would appear a list of ten or more illnesses from which the doctor would select one via the touch screen, mouse or keyboard (numeric selection). That diagnosis (illness #4) would then appear on the top screen after the diagnosis heading (see figure 2). Along with the diagnosis appearing on the top screen would be the standard responses for that illness. By highlighting any statement in the standard response the doctor could delete that specific statement by hitting the "delete" Key. Hitting the "insert" key and typing the desired addition via the keyboard could add additional statements. When the doctor has finished modifying the response, he would hit a button (A. Send and quit) and the results of the top screen would be transferred to the front desk. The second button (B. Quit without saving) would be used to quit without sending. The file would then be sent to a computer at the front desk or directly to a printer at the front desk.

Description: A new on-going project is starting this semester to computerize all aspects of the optical telescope at ISU's Fick Observatory (located southwest of Boone). Ultimately, the telescope will be operable from campus using the Internet. The new team will undertake a design study the first semester. Some of the observatory devices are currently computer controlled while computer interfacing must be created for others. Very likely there will be an additional computer used for the central device connecting everything to the Internet. There are many aspects of the project. The roof must be rolled back, weather data collected and transmitted, sky "seeing" conditions transmitted, telescope pointed at the astronomical source, data collected and partially analyzed, plus many other things. This will be an exciting project. Three computer engineers and one electrical engineer will make up the first team. More team members will be added in the fall of 2001.

Description: The objective of this project is to add functionality to the existing Neural Network Toolkit in ISU's Adaptive Computing Laboratory (ACL). Currently the toolkit supports layered neural networks as a tool for modeling various data systems. However, the toolkit does not implement recurrent neural networks, which can be more useful than layered neural networks for modeling certain systems. This project will implement a recurrent neural network as a part of the toolkit, which will add to the usefulness of the ACL's Neural Network Toolkit and allow for more in-depth data analysis. Requires programming experience in Windows, C++, and Visual Basic.

Description: Personnel ground fault interrupters (GFCIs) provide protection against hazards of electrical shock and are particularly useful in damp locations and where electrical equipment is used around water such as fountains and pumps. Some of the applications may have a variable leakage current, which may be normal (less than 2 ma) and under some circumstances may be relatively high (approaching 10 ma). In this case the normal trip threshold of 4-6 ma would be exceeded and the GFCI would trip and open the circuit. A possible solution to this problem under the above-described conditions would be an "adaptive GFCI." This device (circuit) would effectively adjust the trip threshold slowing in response to increasing standing leakage while continuing to respond to relatively rapid to a quick change in leakage. The time for the circuit to "adjust" for the higher leakage would be relatively slow - possible time constants in minutes. The time for the circuit to "readjust" for the low leakage state would be somewhat faster - with time constants in tens of seconds. As an example, this circuit with a 2 ma standing leakage would trip at 6 ma (total); however, with a 7ma standing leakage, it would trip at 11 ma (total). The circuit must ultimately fit into the existing breaker container. It will be used on 120/240-volt circuits and Square D will own the results.

Description: The objective of this project would be to develop a tracking system for use in a confined area. Two examples of its use would be to track movable equipment (forklifts) in a manufacturing facility and patients in a medical facility. The team would investigate possible methods of tracking including GPS systems and radio signal tracking. Low power consumption, small size and low weight would be design constraints. Continuous signal transmission would not be required (thus reducing power consumption); signals might be sent once per minute.

Description: A team will create a peer-to-peer application that utilizes Microsoft's new dot-Net platform. The application will be written in C# (pronounced see-sharp), Microsoft's new object-oriented programming language and will use XML and SOAP for data exchange. The final product will demonstrate the data and networking functionality of the dot-NET framework and how they can be used in a peer-to-peer application. The source code will be made freely available, so good software design and implementation will be essential.

Description: The objective of this project would be to complete and enhance the results of project Dec00-02 Coin-Operated Washing Machines and Dryers - An Alternative Solution. The results of this project are displayed on the senior design web. A better coin-acceptor mechanism is needed. Programming of the microprocessor must be completed and tested. One enhancement that would be added would be a networking capability to allow the manager to interact with a number of individual washer/dryer controllers to determine usage and modify time and cost settings of the controllers.
Project Number: Dec01-11 (click to view the web site)
Description: The objective of this project would be to develop a controller to maintain a constant temperature of a repaired automobile panel for a specified time during repainting. No contact can be made with the recently painted surface as it would damage the resultant finish. The heat to dry the paint would be provided by a set of infrared lamps. In some case, two stages of heating would be required to correctly cure some paints. For example, a temperature range of 105-110 degrees Fahrenheit for 4-6 minutes is needed to ease the solvents before full heat is applied to finish the curing, which requires a temperature of 140-150 degrees Fahrenheit for 12-15 minutes. The maximum surface area to be dried at one time is 4 square feet.

Description: The Iowa Energy Center is located in a private building at 2521 Elwood Drive. The building contains five office suites, each metered separately for electricity. The electric utility provider is Alliant Energy. The building is located near the end of the Alliant distribution territory resulting in relatively poor power quality (frequent voltage sags and fluctuations with occasional unexplained outages). The Energy Center has a dual interest in improving the reliability and quality of the electric service to its office at the same time as promoting the use of renewable energy. The Center has received approval from the building owner to explore solar photovoltaics as either a supplemental power source or a stand-alone source for all or part of the Centerís office suite.
The Center proposes that a senior design team could take on the project of designing a photovoltaic power system for the Centerís office. The project might be completed in two phases. The Center will provide funds for necessary supplies to complete the project. Procurement or funding for special equipment or diagnostic tools will need to be discussed with the Center. If the project is implemented (pending approval of the building owners), the Center will procure all equipment and services needed to install the PV, batteries, and other ancillary systems.
Phase 1 - Design and Implementation (2 semesters)
This phase can begin in Spring semester 2001 and be completed by the end of Fall 2001. Possible tasks are:
Phase 2 - Real-Time Web Interface
Develop a real-time Web-based monitoring/reporting interface for use with a linux Web server (Apache). This might include:
Project Number: Dec01-13 (click to view the web site)
Description: Most physical signals exist in analog form. Naturally, it is desired to perform some processing on these signals if the objectives of a given application are to be met. Signal processing can be performed by analog means; however, an attractive alternative exists. This alternative is to convert the signal from analog to digital form and then use economical and convenient digital circuitry to perform digital signal processing. If an analog output is desired, then obviously the processed digital signal needs to be converted back into analog form. The objective of this project is to design, layout, and possibly fabricate a chip containing high performance, power efficient data converters with digital circuitry that is targeted at a specific application.
