The project is an integrated health monitoring system. The health monitor determinesand displays a user’s heart rate and measures a user’s reaction time (the latter of which can beuseful for diagnosing diseases like Parkinson’s disease). A complete, digital implementation of thehealth monitor will incorporate topics including combinational logic, common combinationalbuilding blocks, finite state machines, counters, adders, shift registers, and hierarchical design.On the first day of the course, students are shown a functioning health monitor and

Likely reasons for this is the cost to purchase, maintain, and upgrade experimentalapparatus; facilities requirements that can include compressed air and/or hydraulics in addition toelectric power; and the lab space to house the traditional control system equipment, which canhave a fairly sizable footprint. Given the low demand, there are a limited number of vendors whosell control system lab equipment and, hence, the range of apparatus that is available is alsolimited

The two course sequence is named VECTOR (Vitalizing ElectromagneticConcepts To Obtain Relevancy) and adapts existing teaching techniques and laboratories toaddress three inter-related objectives: A) Create an undergraduate curriculum in electromagnetics which is relevant to students and shows the impact of this field on emerging knowledge and technologies. B) Employ modern tools, skills, and techniques to emphasize fundamental concepts rather than teach legacy materials emphasizing rote, analytical solutions. C) Create an effective introductory EM course which will pipeline students into the electromagnetics-photonics curriculum at OSU, including graduate programs.These goals, described in
