(h).Figure 4 provides a more detailed conceptual map for the tasks involved in the data capture andanalysis. As the tank is draining, images are captured (step a.) and pressure versus time data isrecorded (step b). After the draining is complete and the data logging is stopped, the jet lengthvalues, L, are extracted from the images captured by the digital camera (step c). The pressuretransducer values are converted to depth (step d). The time ti at which each image was capturedis used to interpolate in the depth versus time data, and to extract a set of h(ti) valuescorresponding to each of the images used to measure L(ti), (step e). Finally, the L(ti) and h(ti)data are combined to yield a plot of L(h), (step f). Figure 5 is an annotated

When it is connected to a PC, using its WeatherLink software package it can log dataevery 10 seconds. The wireless ISS has a range of 400 feet through walls, 1000 feet line of sight.Other modules include a system designed to be run solely or predominantly in the daytime, thatwill not be needed or rarely used in the night, such as, an attic exhaust fan which will be usedmainly during the day to help keep down the temperature in the roof and operate solely onrenewable energy in conjunction with a thermostat.

The springs are to be usedin the design of the mechanisms to satisfy the required modes/configurations of the modulesduring their: a) transport, b) expansion, and c) the final intended geometry. For full details of thescenario and the activity, refer to Appendix “A”.If there are to be four (4) groups of students [comprised of three (3) or four (4) members] forconducting the experiment, each group will collect data on only one of the sample sets. Eachgroup will then share the results of their measurements with the other groups. In this process,each group has established an average “K” value for “each and all” of the 25 springs in oneassigned set. Since five

Page 15.859.1© American Society for Engineering Education, 2010 Measurement of Hands-On AbilityIntroduction“Practical ingenuity,” according the National Academy of Engineering, is a necessary attributefor the engineer of 20201. Hands-on ability is considered an important characteristic of practicalingenuity2. Two of the ABET criteria address hands-on skills: ability to design and conductexperiments and interpret data (criteria b); and ability to use the techniques, skills, and modernengineering tools necessary for engineering practice (criteria k)3. Employers value hands-onability and routinely ask recruits about hands-on experiences outside of classes4. A “tinkeringdeficit” has also been identified that puts females

Project Progress Updates: The students provide a weekly update to the instructor and their team either via email or through pre-scheduled meetings. Altogether 9 updates are required. In these updates the teams are required to communicate the following: a. What happened the past week? b. What will happen this week? c. What are the major issues the team is facing? 3. Project Report: At the end of the term the teams submit a comprehensive project report. This report provides the details of how the project is executed. It

It is expected that the techniques employedin the controller designed for the laboratory experiment will likely be used by the students intheir subsequent employment after completion of their college education.References1.

judged to be inappropriate. The laboratory experience required a low-voltage replica ofcommercial three-phase power: sinusoids with 120° phase separation. The faculty design teamwas unable to find such a source commercially at low cost and designed, built, and tested severaldifferent sources. In addition to a transformer solution, two electronic circuits were implementedin the initial trials of the laboratory exercises: (a) digital synthesis using synchronized counters,D/A conversion, and wave shaping, and (b) digital synthesis using EPROMS and D/Aconversion. Each of these three-phase synthesizers was developed with an estimated parts costof less than US$10 (assuming appropriate DC power availability).The design and implementation of the sources
