170. Definedas the application of complex decision making to the operation of physical systems, mechatron-ics is usually introduced in upper-level electrical and mechanical engineering courses. However,the infusion of microcontrollers in nearly all phases of everyday life indicates that all engineersshould have a working knowledge of mechatronics concepts and their impact on products, proc-esses and system design.Teams of three or four students are provided with a pre-assembled mobile robot called an anklegrabber, shown in Fig 1. This robot is constructed from simple components designed at IowaState plus wheels, motors, and other standard parts. These components are included in a kit fur-nished to the students. A parts list can be found in

Many software packages have been developed to help designers achieveand produce their designs more efficiently. One of these classes of software packages is thehardware description languages or HDLs. VHDL, a hardware description language for Very High Speed Integrated Circuits(VHSIC) was developed in the early 80’s to help the government standardize methods of Page 2.49.1describing hardware designs. This later became IEEE standard 1076 [1] and was modified andupdated in 1993. Most digital designs today use the

Conventional chalkboard and viewgraph presentation methodssometimes fall short of conveying the abstract concepts that need to be mastered.Computational tools have evolved over the recent past to allow fast rendering of two andthree-dimensional graphics on desktop computers and workstations. Precise numericalcomputations on limitless variations semiconductor device structures are possible. Methods for the illustration and presentation of these results for non-experts must beboth interactive and revealing [1][2][3].

Recommendations vary from typical conservation measures such as recycling pallets andcardboard to direct process modifications that reduce water or chemical usage. While somerecommendations are general and can be applied to any industry, others are industry-specific.1. IntroductionThe Energy Analysis and Diagnostic Center program (EADC)was established by the U.S. Departmentof Energy (DOE) in 1978 to assist small and medium sized manufacturers in improving energyefficiency while training engineering students in energy efficiency principles. This was accomplishedby establishing EADC’s at thirty universities around

definition of biologicalengineering at the expense of strategic perspective. It is time to assess our positions regarding whathas been accomplished and where future efforts might need to be applied.Here are some of our accomplishments:1. A significant minority of faculty have accepted biological engineering as their discipline. My assessment is that this group may have reached majority in some places, but that the largest group of faculty are those who have accepted the change to biological engineering as an experiment without final results as yet. They remain somewhat skeptical, certainly unenthusiastic, and have yet to accept where they will fit into the new discipline. The committed biological engineers

There are many ways of attaining the knowledge, skills and attributes needed,based as in all professions on some combination of formal instruction and practical experiences.We start with some definitions. The Engineers' Council for Professional Development say that"Engineering is the profession in which a knowledge of the mathematical, physical, [social andpolicy] sciences gained by study, experience and practice is applied with judgment to developways to utilize, economically [and ecologically], the materials and forces of nature for the benefitof mankind."(1) Words in brackets were added in a proposed revision of the

It seemed that no matter how much explanation and how manyexamples were provided in class, many students were unable to correctly conduct a basicstatistical analysis. It got even worse when students were presented with a new situation thatdidn’t match earlier problems. Lecture was just not enough.

type DAC, and Successive Approximation type ADC converters.Digital to Analog Converter (DAC) Characteristic: When we select a Digital to Analog Converter (DAC) chip for an application, we mustconsider three characteristic associated with a DAC. First, resolution or step size defines thesmallest voltage or current change possible for the DAC output signal. For example, an 8-bit DACthat generates a maximum output voltage of 5 volts has a step size or resolution of (5V / 2 8 ) = 19.5mV. Sometimes, the resolution is stated in the percentage value. For the 8-bit DAC, the percentresolution is (1 / 2 8 ) x 100 = 0.39%. Settling time is the time required for the DAC output to settleto 99.5% of its new value. Typical settling time for a
