Registration for particular course sections is sometimes "closed." This may be done when the section is physically full (there are no more seats in the room in which the course will meet), to balance the enrollment among sections of the same course or to allow time for students from particular majors who are required to take the course to enroll. You can request enrollment ("to be added to") in these section. That way in which this is done depends on the academic department offering the course. While the details vary, it generally involves completing and submitting a form that can be found on the MSOE Community. Here are some useful links related to this particular situation and registration in general:

Students sometimes panic when they see all the sections of a course they need are closed. This is generally not appropriate. If you are on track, MSOE will find room for you in all your necessary courses and create a workable schedule for you. This is guaranteed (see MSOE MSOE Guarantee - About MSOE, About MSOE for its exact wording). Note however that you are not guaranteed particular sections, professors, or schedules. In fact, when you submit a request to be placed in a closed section MSOE reserves the right to completely revamp your schedule to fulfill your request.

Note: If any of the links above become broken, please e-mail me (Dr. Tritt) to let me know. You can also then do a Google search for “MSOE Request to Enter a Full Section of a Class” to see if you can find the new link.

Books, books, books

Posted by Charles Tritt Feb 23, 2015

To make a long story short, I was just reminded how difficult it can be to find information resources that our library makes available. If you’re looking for information you think should be available but can’t find anything, talk to one of your professors or a member of the professional staff in the library. The MSOE library budget is substantial and they provide access to a lot of valuable information.

For example, follow this link to see a list of some of the biomedical engineering e-books the library provides full text access to: http://ieeexplore.ieee.org/xpl/bkBrowse.jsp?queryText=Biomedical.

MRI Safety

Posted by Charles Tritt Oct 6, 2014

Here are a couple of internet links involving MRI safety I thought might be of interest to BE program students, faculty and alumni.

The MD&M Chicago trade show will be held October 15 and 16. The real purpose of this show is for companies to show off their medical device related products and services. It is focused on design and manufacturing. It's a big show, but you can really see it all in a day or a little less, so there is no need to attend both days. In the past, they've supposedly charged people to attend, but you could generally get free passes by registering (i.e., providing your contact information for their database). I assume this will be the case again this year.

I recommend juniors and seniors consider attending. Doing so could allow you to make contacts that would be useful for both your design project and job search. It would not be appropriate to openly promote yourself for employment (i.e., pass out resumes) at the event, but there is nothing wrong with telling the people you talk with that you'll be graduating soon and are starting to look for a job.

Sophomores and freshman, be aware this show exists and takes place annually, usually in mid-October.

One of the major challenges in biomedical engineering is how to deliver the benefits of modern medical understanding to people in developing nations. Here are some really cool ideas: WHO | Compendium of innovative health technologies for low-resource settings.

What We Teach

Posted by Charles Tritt May 13, 2014

This list of rules mirrors what we teach in MSOE's BE design sequence courses: http://www.qmed.com/mpmn/medtechpulse/10-rules-designing-great-medical-devices. It is nice to have some external validation of our ideas.

Our program is conducting a “stakeholder” survey to help us set curricular priorities. So far, nearly all (97%) of the respondents have been program alumni. This graphic lists the most common words in the responses to the “job description” question, with size corresponding to frequency. It gives an idea of what our allumni do…


The 2014 MSOE BE Senior Presentations will take place on Friday, May 23 from 8:30 to 10:30 am in the Grohmann Auditorium.  The “auditorium” is a large classroom like room on the first floor of the Grohmann Museum which is located at 1000 North Broadway, Milwaukee, 53202. Coffee and continental breakfast items will be provided.  The presentations will also be webcast on the MSOE Biomedical Engineering program channel on ustream (http://www.ustream.tv/channel/msoe-biomedical-engineering-program). While your wait for our video feed to start you can watch live video from the ISS at – http://www.ustream.tv/channel/iss-hdev-payload.

Parking will be available in any MSOE lot on the day of the presentations.

Presentation topics and schedule:

8:30 – 8:55 am           Team 2014-003 – Excessive Blood Loss, Massive Air Embolism, and Drug Administration Perfusion Simulator

9:00 – 9:25 am           Team 2014-004 – Electrocardiogram Derived-Respiration Laboratory System

9:30 – 9:55 am           Team 2014-001 – Pneumatic Research Device to Impact Traumatic Brain   Injury in an Experimental Rat Model

10:00 – 10:25 am      Team 2014-002 – Mobile Heat Illness Monitoring System (MHIMS)

The Senior Design Show, a poster session style event involving all MSOE programs, will take place after the presentations from 11:00 am to 2:30 pm. The biomedical engineering teams will be in MSOE’s Walter Schroeder Library for the design show.

Medical device cyber security is currently big issue in the medical device industry. Here is a short news story on the topic with some interesting links: http://www.qmed.com/news/fbi-warns-medical-device-hacking-risk.

The last paragraph struck me as particularly interesting. In the same way the post office sometimes gets blamed for lost checks that were never mailed, I think the FDA sometimes gets blamed for complicating things that medical devices companies don’t know how to or simply don’t want to do. I went to the FDA website and found the following Guidance Document: http://www.fda.gov/medicaldevices/deviceregulationandguidance/guidancedocuments/ucm077812.htm (those of you how have heard my FDA presentations know how useful guidance documents can be).

Many students become interested in biomedical engineering by way of prostheses. Creating prostheses is only a small part of what biomedical engineers do, but I think is appealing because the need is obvious and the devices are relatively easy to understand. Here is a link to a low cost prosthetic hand that has been developed in part in South Africa: http://www.qmed.com/mpmn/gallery/image/robohan (if you're impatient, start about 4 minutes into the video). I first heard about it while visiting an MSOE BE program alumnus there.

Here is a link to an article describing how four LVAD patients have died due to poor device instructions: http://www.qmed.com/news/thoratec-warns-hospitals-after-lvad-patients-deaths?cid=nl.qmed02. These incidents emphasize  the importance of the broad and careful considerations necessary to create safe and effective medical devices. In addition to “traditional” technical design issues, biomedical devices require careful consideration of everything from overall concept to packaging and labeling (including user instructions).

I just received notification that our program will be getting 5 Intel Galileo development boards (http://www.intel.com/content/www/us/en/do-it-yourself/galileo-maker-quark-board.html). These boards combine Arduino functionality with a Linux system-on-a-chip. Our intent is to use the boards to eliminate the need for a laptop or other external computer in design projects involving Arduino boards. They may also be useful in enhancing the capability of Arduino only design projects. Here is what I put in the application to get the boards:

How will you use the boards…

The Galileo boards would be used in selected capstone design projects in our biomedical engineering (BE) design sequence courses (BE-3002, BE-4000, BE-4001 & BE-4002). Students are currently responsible for obtaining their own hardware as needed for their projects, but are assisted in their efforts by the faculty. Over the past several years about half of all BE capstone projects have included Arduino embedded computers with about half of these programmed using the Arduino IDE and the remainder using other more advanced tools. A number of these projects also involve laptop computers to complete the user interfaces. The Galileo boards would be used to provide an intermediate solution between the simple LCD based Arduino interfaces and the need for connection with expensive and heavy laptops.

What is the course focus…

These are BE design courses. In them, students must produce working prototypes. All projects are biomedical engineering related. Some projects involve the design of medical devices, but others cover other aspects of the field including assistive technologies, athletic equipment, and research related devices. While the devices being designed differ, all projects involve the basic design process including compliance with FDA requirements and international standards as appropriate. Most projects involve the integration of analog electronics, mechanical components and software. The consideration of human factors in the user interface design is stressed.

The boards are scheduled to arrive within 30 days. The award also includes free access to the “Getting Started with Intel Galileo” by Matt Richardson e-book. Intel has also created a Maker Community and a Maker Community for universities - https://communities.intel.com/community/makers and https://communities.intel.com/community/makers/universities.

Thank you Intel.

Congratulations to two Class of 2015 design teams for placing in MSOE's business plan competition. Team gluocChem finished 2nd and will receive $1,500 and Team Neonate finished 4th and will receive $500.

Congratulation to BE design teams 15-1 (Novel Glucose Monitor) and 15-2 (Neonate Cardiopulmonary Bypass Simulator) for being selected as finalists in this year’s MSOE Business Plan Competition. Good job and good luck in the final round.

This has the potential, really the likelihood, to be the medical breakthrough of the decade: http://www.usatoday.com/story/tech/2014/01/16/google-smart-contact-lens/4540727/?csp=fbfanpage. Continuous glucose monitoring is the holy grail of biomedical engineering. There has been numerous attempts to develop a workable technology, but they've all had serious shortcomings. This one might just work.
