Title: Automated Medical Patient Evaluation System - Phase 2
Description: Updating patient medical records at the local McFarland Clinic is currently a costly, time-consuming process. After completing a series of patient interviews and diagnoses, the physician dictates from handwritten notes the data to be entered into the patients’ files. Later, this dictation is transcribed at a cost of $0.25 per line and sent back to the doctor for review, signature, and eventual filling. The process takes several days during which the records are held in suspense and are not readily available to other medical personnel. A previous design team has produced a simple, pull down menu driven program that allows the doctor to record routine diagnoses (which comprise a major part of the workload) directly during the interview. This data is immediately printed and entered into the patient’s records. In the second phase of the project, the client doctor will test the software, and revisions and improvements will be made. Additional software will be developed to allow medical staff to modify or add additional diagnoses templates easily. Expanding the system to accommodate additional doctors and medical specialty areas may be considered if time permits.

Description: The objective of this project is to develop a wireless communications system. For example, one person must read or study and the roommate wants to watch television in the same room. The wireless device would plug into an existing audio outlet on the television and transmit a radio-frequency stereo signal to a small battery-powered box. In addition, the box would contain an on-off switch, a volume control, and a stereo headphone jack.

Description: OSCAR and Cybot, the department’s autonomous robots, can now be controlled through an Internet wireless remote link. Thus, it is possible for elementary students to program and control either robot from their home classroom at a site remote from ISU. The results of this programming can be viewed via OSCAR and Cybot’s video link back to the elementary school. Three groups will participate in this project: (1) students from the Curriculum and Instruction Department, College of Education, (2) students in an ECPE senior design team, and (3) an elementary school fifth to eighth grade class yet to be named. The Education students will: (1) identify an appropriate elementary class level and appropriate robotics topics, and (2) develop instructional materials for a short, introductory robotics course that will culminate with the remote programming and control of OSCAR and/or Cybot. Members of the ECPE senior design team will work in conjunction with the Education students to develop the instructional materials package, providing them with the technical information and background necessary to develop the robotics and programming materials. The ECPE team will also develop any additional simulation software or hardware that the robots might need to function as desired. Near the end of the second semester the introductory robotics course will be taught to elementary school fifth to eighth grade classes who will provide evaluative feedback and recommend improvements. Finally, a self-contained, short version of the course will be developed for use as a remote, introductory demonstration in the same manner that demonstrations are presented to students visiting OSCAR and Cybot on campus.

Description: The objective of this project will be to define a set of robot-related projects that might be conducted in conjunction with a group of grade school students, who are in the fourth grade or above. Examples of possible projects might include any of the following activities:
2. Battlebot activities
3. Special purpose search-and-retrieve activities
2. Project equipment requirements both at ISU and at the 4-12 school
3. Project communication requirements
4. Project strengths and weaknesses
5. Project priorities
Project Number: Dec02-05 (click to view the web site)
Description: With the advent of GPS systems, it is possible to closely control agricultural inputs such as plant/seed density and fertilizer in small areas within a given farm field. Accurately measuring crop yields at different field locations is critical to setting these inputs. The accuracy of a crop combine yield monitor depends upon accurately measuring the swath width of the crop being harvested. A previous senior design team developed an optical imaging method of measuring swath widths with fair success. National Instruments has agreed to provide digital signal processing hardware and software that should improve the results significantly. While improvements in both hardware and software (image processing algorithms) are possible, the major improvements are anticipated from the software efforts related to image analysis.

Description: The client has developed software that works with the PalmPilot to build portable measurement devices. The client would supply 2 PalmPilots and development software. The objective of the project would be to develop one or more custom voltmeters, data loggers, etc. using the software and data acquisition (DAQ) cards. The client will specify the particular applications of interest.
Project Number: Dec02-07 (click to view the web site)
Description: The objective of the project would be to develop a wireless interface between two PalmPilot or HandSpring devices using two Motorola Talkabout radios. During testing, a third Talkabout-PDA would be used to try and intercept messages between the first two systems.

Description: The objective is to develop a riflescope system that will auto adjust the crosshairs to compensate for bullet drop. Two inputs would be incorporated into the adjustment subsystem. The first would be a laser rangefinder and the second would be a handheld input device into which the user would enter bullet coefficients, bullet velocity, and estimated wind velocity. A small stepper motor would be used to adjust the crosshairs.

Description: The objective of this project is to develop a non-athletic track-oriented pedometer that might sell commercially for no more than $100. It features would include: (1) a distance calculation based upon global position satellite (GPS) data, (2) elapsed time measurement, and (3) average speed in miles per hour.
Project Number: Dec02-10 (click to view the web site)
Description: Iowa State University owns the only virtual reality auditorium in the nation that can accommodate a large audience of up to 250 people. This auditorium has a 30'x 15' screen controlled by 5 projectors. 4 of those projectors are dedicated to display interactive stereoscopic virtual reality worlds to the audience. There is a tracking system that allows a single user to interact with the virtual worlds. This project is targeted to enable the entire audience to simultaneously interact with the virtual world. This means that each seat in the auditorium needs to be instrumented with a set of simple controls, these individual seat controls need to be tied to a centralized processing system, and the collected data needs to be sent to the virtual reality application to modify the displayed images. All this has to happen in very tight real-time constraints. The goal of this project is to design the hardware to be installed in each seat, the software to collect all the data, the software to process the data, and the software to incorporate that data into the virtual reality application. Students will have to analyze several virtual reality applications, specify their requirements, and design a solution that can be integrated into the VR Juggler system, our virtual reality operating environment.

Description: The objective of this project is to develop a web browser for first time users, particularly senior citizens and young children. The browser needs to be simple, easy to understand, easy to read for people with less than perfect eye sight, and couple directly to a good search engine such as www.goggle.com.
Project Number: Dec02-12 (click to view the web site)
Description: Many senior design and other class/design projects within the department require a micro controller unit (mcu) whose requirements are simple enough to be met by a PIC such as the 16C872 or 16C877. However, before they can be used in a design project, these units require additional components and design, often beyond the expertise or time available within the design team. The objective of this project is to design and fabricate an evaluation/development board for each PIC, similar to those found in the CprE 211 laboratory, which will provide the required power supply, frequency source, and other supporting components needed to realize a fully functional, low cost, “off-the-shelf” mcu for use in senior design projects. Having such units readily available will allow senior design teams to concentrate on completing their assigned design rather than expending time and effort on an ancillary component. Full documentation will include tutorials and design guides for using the PICs in various applications.
Project Number: Dec02-13 (click to view the web site)
Description: The Center for Non-Destructive Evaluation has a FAA-funded research program to develop a pulsed eddy current inspection system for civil aircraft. The system allows remote access to circuit boards by a personal computer at distances up to 200 meters. The project team would help develop a new lightweight version that would connect to a laptop computer via a USB port. New drivers will also have to be written.
