BackgroundThis paper is an extension of a paper presented previously at the 1995 ASEE annualconference1 that detailed the techniques for designing a microprocessor lab around the 29205processor. The lab station described in that paper included both the SA-29205 demonstrationboard for the processor and a separate terminal for interaction with a host computer. The labstation in that microprocessor laboratory is evolving away from the need for the separateterminal by using the processing power available in

These laboratory experiences are designed to lead students, literally bytheir hands-on experimentation, through the use of technology in support of many everydayactivities.Laboratory experiences, inspired by work done at MIT1,2, typically involve the design andconstruction (out of LEGOs) of simple models of familiar real-world systems, including anelevator and its controller, a garage door and its opener, a computer-controlled car, and a homesecurity system.

Now we will turn to some basic comparisons of the threesystems.Credit Systems: Mexican courses carry 6 to 10 units, usually two units or credits for each hour oflecture, and one unit for each hour in laboratory or working groups. Some schools assign units forthe time spent on practical work, class projects, or outside assignments. In general, a 6-unit courseis three lecture hours per week without a laboratory, while 8-unit courses have three hours of lectureplus lab or practical work. Mexican semesters can be as long as 18 weeks, with 2 weeks for Page 2.308.2examinations. Thus, a 6-unit course represents about 48 hours of

North Texasto bring the Mechanical Engineering Technology (MEET) and the Manufacturing EngineeringTechnology (MFET) programs closer together so that the students in either discipline getsignificant exposure to both design and manufacturing functions. A project to manufacture testequipment for laboratory use was selected as a means of demonstrating the usefulness ofconcurrent engineering. This selection had some advantages since the fixtures, tools, devices,and test specimens could be used in other labs, thus reducing the laboratory operating costs, andat the same time giving the students realistic problems to solve in the process of learning vitaldesign and manufacturing functions.

CAD/CAM and computer numerically controlled (CNC) machine tools play importantroles in modern manufacturing engineering.Indoctrinating students in the modern production process is crucial. ME 435, the IntermediateManufacturing course offered by the mechanical engineering department at Christian BrothersUniversity (CBU), addresses this need. First offered in the fall of 1996, the class revolves aroundthe use of computers to integrate the design, analysis, and manufacturing phases of production.Students in ME 435 use the facilities of the Integrated Laboratory for Manufacturing Education(ILME) developed at CBU under a National Science Foundation grant.Students are first introduced to parametric design methodology, including part and

The calibration curve, i.e. amplifier voltage as a function of force is shown inFigure 4. An amplifier gain was selected to give a full scale amplifier output spanning a +/-5 voltrange for a loading equivalent to the maximum expected injection pressure. Because the straingages produce linear output, it is usually not necessary to cover the entire load range withcalibration weights.EXPERIMENTAL SET-UP FOR ENGINE TESTING The heavy-duty diesel engine used in this study is set-up in the University of Michigan’sW.

Another faculty member, who teaches the Page 2.162.3 Electromagnetic courses, was enlisted for this project. An experimental set-up was established in the Energy Conversion Laboratory to verify the results from the Matlab-based model. This research project was sponsored by a motor-drive manufacturer who offered a position to the student after graduation. Unfortunately, the student accepted a better economical offer.

Moreover, the fiscal, facility, and expertise constraints of a small institute limitviable projects, particularly experimental endeavors. To meet the research requirements forpromotion, three junior, untenured faculty members (an electrical engineer and two physicists)took the initiative to form a cross-discipline, off-campus collaborative research effort with asenior, tenured physiologist at a mid-sized research university.

Bythe end of the second lab the students are ready for more involved work such as tensile testingand the effects of heat treating.Another topic that needs attention is the use of numbers. Most of the students have never given aphysical meaning to a number except for length. Presenting such concepts as stress and strainbefore actually doing the laboratory work causes the majority of the students considerableconsternation. Only after doing several tensile tests and

Therefore, the circuit has a minimum impedance anda maximum current at this frequency. However, it is hard to see from the formulas how thereactance and the current respond to the frequency change, when the circuit frequency isapproaching the resonant frequency. It is also difficult to introduce the sensitivity of a RLCcircuit and the effectiveness of the capacitance or the inductance to resonance or sensitivity.RLC circuit resonance can be demonstrated in a laboratory.

The integration of these three topics in which students design, simulate,build and test a data acquisition system will help them to understand a practical industrialapplication. In this paper we will use a PC Interface card to connect the interfacing circuit whichis on a breadboard to the computer. The interfacing circuit will be connected to an analog circuitthat measures temperature. All engineering and engineering technology school laboratories areequipped with microcomputers. The advantage of using a PC interface card is that with amoderate cost for interfacing cards, the computers can be used for the programming of the digitalcircuits
