Control ScreenThe manual control system is mainly designed for debugging purposes. The benefit of thissystem comes with event processing. In figure 5, the event list is shown. This allows the systemto respond to events triggered by inputs connected to the GPIM(s).The list contains a name and description of each event to aid the user as the event list willprobably have many events for an average size home. Adding and editing an event is verysimple using the built-in event editor. The system also has safeguards to prevent edit entrymistakes.The security tab, shown in figure 6, displays configuration parameters for the security system.Modeled after standard security systems, the security interface features multiple user codes withlogging

For the 800 million people who go hungry each day and the one billion who lack access to clean water, poverty is an absence of opportunity. Engineers Without Borders is responding to this urgent need, helping people in developing communities gain access to technologies that will improve their lives. We believe that technology, when appropriately incorporated into each community's social, cultural, economic and political context, can drive extraordinary change.The focus of EWB is on developing the technical capacity at the local level in developingcountries to ensure that innovative

Judging Robotics ProjectStudents are required to demonstrate their finished robotics assistive devices to a Judges Panel.The judges are given the following instructions:During the ten sessions of this program, we emphasize the following Massachusetts frameworkstandards:2.1 Identify and explain the steps of the engineering design process, i.e., identify the need or problem, research the problem, develop possible solutions, select the best possible solution(s), construct a prototype, test and evaluate, communicate the solution(s), and redesign.2.2 Demonstrate methods of representing

The basic method is that that two programmers worktogether on a piece of code on the same workstation or terminal with one acting as the "driver".This "driver" actually types and inputs all the code, while the other programmer watches andoffers advice both methodically and in syntax correction.

instruction process, we incorporated this into the real-time quiz framework. Initially, each learner would take the quiz individually at their owncomputer workstation. The instructor would monitor the results on a separate screen, not visibleto the learners. Once the allotted quiz time had elapsed (which typically ranged from 5- to 10-minutes) the learners would break into their assigned teams. The teams were assigned by theinstructor at the beginning of the semester and were usually based on declared major. Teamsizes ranged from three to four learners, with four being the maximum. After forming into theteams, the learners were tasked with discussing the real-time quiz question(s) being asked andwere to arrive at a team answer. Each team would then

that are unwanted by the computer science students and also thecomputer structure details that may be unwanted by the electrical engineering students. Studentsdo design and build digital electrical circuits, but no discussion of the electrical nature of thecircuits is included. The power supply is just a source of 1’s and 0’s for the computation, and thewires are just physical implementations of pencil lines on paper. Of course, eventually the twogroups of students must diverge and pursue those details related to their major disciplines.Conveniently, that divergence comes right at the end of this introductory “digital circuit design”course. The engineering students follow this course with a “digital computer circuits” coursethat does teach
