In their book Lean Thinking, James Womack and Dan Jones1 outline five steps forimplementing Lean: 1. Specify the value desired by the customer. 2. Identify the value stream for each product and challenge all waste. 3. Make the product flow through the value creating steps. 4. Introduce pull between all steps where continuous flow is possible. 5. Manage toward perfection by continuously improving the process.

(complete surface removal) or surface cleaning, some are known to be anisotropic suitable forprecision microstructure manufacturing. For instance, KOH is a chemical compound that attackssilicon, producing characteristic anisotropic V-etch, with sidewalls that form a 54.7° angle withthe surface (35.3° from the normal). This etch process is independent of the doping concentrationof As, P and Sb. For B, the <110> etch rate drops quickly at high doping concentrations though.Such precision V-etch by selective wet etching is the foundation of the bulk micromachining. The two key capabilities that lead bulk micromachining to become a viable technology inMEMS are: (1) Anisotropic etchants of Si, such as ethylene-diamine and pyrocatechol (EDP

Imbrie of Purdue University.Student SelectionThe basis for selecting students for the CpET learning community was their SAT scores. Theaverage SAT score (math and verbal combined) for all incoming CpET first-year students for the2004-2005 academic year was determined. The student SAT scores were then sorted identifyingall students that had scores within plus or minus 1 Sigma of the overall average. This criterionwas chosen to establish a somewhat homogeneous group by preserving the integrity of thelearning community relative to retention.Based on historical data

Technique and Its ApplicationsSynthesis of a Slider-Rocker MechanismThe slider-crank mechanism illustrated in Figure 1 consists of a crank (O2B), a connecting rod(BC), and a slider (C). The mechanism to be designed has a stroke of 120 millimeters and a timeratio of 1.4. The time ratio is defined as the ratio of time required for the slider to complete aforward stroke to that of a return stroke. If the motor driving the crank at the fixed pivot (O2)rotates counter-clockwise at a constant speed, it would take more time for the slider to travelrightward (forward) than leftward (return).

The capstone course exposesthe students to open-ended problems and also provides a framework for their evaluation.1 Eachyear, students are challenged to formulate a project that is complex enough to meet therequirements, but not so complex that it cannot be completed. The ubiquitous car jack has beendesigned numerous times, while an aircraft that runs on hydrogen fuel is probably too ambitiousfor even the most dedicated team of students.

When Motorola spin off their microprocessor division to Freescale Inc., 5 the68HC11 EVB became very hard to obtain. The alternative EVB made by Axiom is moreexpensive. 1 Another draw back is that the alternative board has limited functions as comparedto the original Motorola 68HC11 EVB.1,9 In order to extend the use of the 68HC11 EVB and keep
