The tags are passive, i.e. they are powered by thesurrounding radio frequency (RF) field which is radiated by the reader (interrogator) antennalocated in the vicinity of the tag. Advances in the RFID technology have reached such a statewhere they are now widely used in various aspects of industry, giant retail stores, and large scalewarehouses. RFID systems applications in location estimation of stationary objects have been investigatedby various authors. They introduced methods for the localization of passive tags within apredetermined interrogation range of the reader and presented methods to

Of the four primaryengineering fields listed above (control systems, electrical, computing, mechanical), our studentslack the in depth knowledge of PLCs that an electrical or electronics engineer would haveobtained.The course was developed with both a lecture portion and a lab portion. The lecture meets twicea week for 50 minutes each and the lab portion is once a week for 1 hr and 50 min. The lecturetopics include discussions on the following: Automation Safety and Error Proofing PLCs Input devices (electrical and mechanical) Output devices (electrical and mechanical) Numbering systems

The students are given a specific design task; currently the design task has beento build a walker robot.Course DescriptionThe current format of the course contains three components: (1) The use of a commercialParametric Modeling package. Currently the SolidWork software is used. (2) An understandingof the available new technology, such as using a Rapid Prototyping (RP) machine and using a 3Dscanner. (3) The designing and building of an actual product to further reinforces the conceptsand principles learned. By integrating the project into the 2nd half of the course, the insights andstrengths of using the available new technologies can be better observed.The course is structured in a 2-3-3 format (2 hours lecture, 3 hours lab, 3 credit

ABET outcomes forManufacturing Engineering Technology programs explicitly state that graduates should beprepared for “careers centered on the manufacture of goods” 1. The ability “engage in lifelonglearning” is also explicitly stated in the general technology program outcomes 1. Understandingwhat skills are required of graduates and preparing them to be lifelong learners entails learningabout the types of careers these students will pursue. One way of gaining this information isthrough ABET mandated advisory committees. While these committees can help withidentifying industry trends and skill

These valvescompletely open at any pressure, and the internal cross-sectional geometry of the flow path isconstant throughout the flow range of the valve. The valve design used by the smallmanufacturer is not direct-acting; it falls into a classification known as pilot-operated valves.Pilot-operation uses the pressure drop, or differential pressure (psid), to apply force against aspring-loaded

To meet these new goals, the course is being reconfigured such that 2/3 instead of 1/3 ofclass time is spent on CADD. This reconfiguration has been implemented on a pilot basis in oneof three sections of the course.In the process of redesigning the course, pre-existing goals must not be thoughtlessly ignored.Therefore, a reconfiguration method was developed that maps the connection between lessonplans and course objectives from the original to the new structure.

Since students communicated that they were notgiven formal training in the LMS, their engagement within the system was delayed.Finally, two major findings in the study were that the LMS must (1) contain the necessary tools thatstudents require to support their courses and (2) that instructors must set up the LMS effectively toencourage both engagement and a “sense of community” for students.
