The purpose of the new laboratory is to supportinstruction of two of the five new courses: ME 105 Fundamentals of Mechatronic Systems Engineering andME 190 Electromechanical Systems and Microprocessor Applications.INTRODUCTION “Mechatronics” is a melding of two English words Mechanical and Electronics. The terminology wasfirst used by the Ministry of International Trade and Industry (MITI) of the Japanese government in the early1970’s. The original notion of mechatronics involved the development of automated production of consumer lproducts such as the Canon SLR auto focus camera . The application of this technology was soon extended

It is performed in a discussion-group (team) setting,and therefore allows participants to suggest improvements and alternatives whilst evaluating.

Most digital trainers provide only a clock waveform, a certain number of switches to supplysteady logic levels and perhaps a push-button switch as inputs to a test circuit, To record the output(s) of thetest circuit, LED’s are provided. While this is adequate for combinational logic circuits it is a poor substitutefor studying sequential logic circuits and provides no permanent record. It was desired to have a extremely user-friendly, programmable, logic-level signal generator withseveral outputs and the ability to simultaneously record several digital signals. It was also desired to keep thissystem inexpensive and to have a permanent record of test circuit input/outputs signals.SOLUTION Our

He saidhe had heard that too, but not until after he had been doing it for about 15 years. I remember very distinctly the problems I had as a freshman student at Purdue in trying to weld cast iron.We were admonished in class that welding of cast iron with freshly ground abutting surfaces was possible, butdifficult, and that welding of broken parts with rusted sutiaces was impossible. That was the technology of the1950’s. By the 1970’s, I was using eutectic filler rod to successfidly braze cast iron for repairs, but I had no ideawhether there were improvements beyond

In thedecade following its founding, additional courses and programs were added in agricultureand ornamental horticulture. In 1920, the regular four-year offering was limited to athree-year program. During the depression years, the curriculum was reduced to twoyears. In 1946, to fulfill the increasing need for technically trained men and womenduring the post-war period, industrial-technical programs were added.

Since performance, such as critical thinking or valuing life-long learning, is often not directly assessable, indicators of performance must be sought. If we can find evidence or indicators that the desired activity is taking place at the expected level, we can say we have met our performance criterion and thus, achieved our desired outcomes. Step 4. Specify assessment methods to be used for data collection for each of the objectives/criterion. It is important to note that this is a simplification of the

Then,we will describe the Component Icon groups, and the Instrument Icons. Five examples will show the convenienceand the speed of Electric and Electronic circuit simulations. In the first example we will discuss the use of afunction generator, oscilloscope, multimeter, ammeters, and voltmeters to supply and display AC and DC signals.The second example will be a two-stage amplifier with a voltage gain of two.
