1. Biomedical design projects developed around OEM devices Jean-Michel I Maarek Department of Biomedical Engineering University of Southern California Los Angeles, CA 90089 jmaarek@usc.edu

2. Senior projects design course BME 405L: Senior Projects – Measurements and Instrumentation 15-week course with laboratory organized in 3 hours of classroom time + 3 hours of laboratory time per week Offered twice a year to accommodate all BME seniors (~ 50 students year) Enrollment: 18 students in Fall 06 and 27 students in Spring 07

3. Goals of Senior Projects course Course goals: to integrate applications of computer programming, signal transduction, data acquisition, data analysis, and signal processing in the design of medical and laboratory instrumentation LabVIEW: standard in academic and industrial environments for data acquisition, interfacing of instruments, data analysis, and graphic user interface Students apply LabVIEW as a tool for the design of computer-based medical virtual instruments

4. Topics addressed in BME 405L LabVIEW programming basics Software architectures Development of software requirements and use cases Properties of signals and data acquisition Instrument control Graphic user interface Light, pressure, and temperature transducers

5. Format Time divided between instructor-led presentation (1/3 time) and student activities (2/3 time) Activities to develop programming skills and practice concepts discussed with instructor Instructor and teaching assistant roam the room during activities and assist students in their work Six “canned” laboratories cover basics of data acquisition and instrument control, static and dynamic calibration of pressure, temperature, and light transducers, and a virtual frequency analyzer 8 week project to develop a computer based medical monitor using an OEM device

6. Term project with OEM device OEM device: Ipod (Nonin) pulse oximeter and M2600 NIBP monitor (Colin Medical) Programmer’s manual Serial (RS 232) control and communication for implementation of medical monitor with several modes of measurement or signals Graphic user interface Data storage

7. Functional requirements from use case

8. Project deliverables LabVIEW program Graphic User Interface Demonstration (rated by other group of students) Design report

9. Conclusions OEM device provides realistic experience in terms of technical integration, use of technical documentation Use case entices students to think about use of product by others. Graphical user interface also reflects emphasis on users Favorable comments from industrial advisory board and high student evaluation marks but no formal evaluation
