Mechatronics refers to the growing number of commercial products and industrial processes that involve the integrated application of mechanical and electrical engineering concepts. Despite the importance of this interdisciplinary area, many of today's engineering graduates are unprepared to function competently in environments that require them to optimally integrate electrical and mechanical knowledge areas. In addition, engineers with better communication and teamwork skills are needed to ensure U.S. competitiveness in today's global economy. In order to address this competency gap a team of faculty members (consisting of faculty from both ME and EE departments) started work in the late nineties to integrate Mechatronics-based activities at all levels of the undergraduate engineering curriculum at University of Detroit Mercy. These included a new senior level technical elective in introductory mechatronics along with mechatronic activities in freshman design and in the introductory electrical engineering course for non-EE majors. This effort has been very successful, and now mechatronics activities take place in many pre-college programs that the school runs. Just over two years ago this team received a National Science Foundation grant to build on the earlier efforts by developing two new advanced courses in the area of Modeling & Simulation of Mechatronic Systems and in the area of Sensors & Actuators for Mechatronic Systems. The first of the two courses has been taught in Winter 2005 and reported on, while the second course was taught in Fall 2005. This paper will describe in detail the construction of the Sensors & Actuators course, as well as results of outcomes assessment conducted by an assessment expert who is also part of our team. © American Society for engineering Education, 2006.

Frontiers in Education (FIE) Conference

作者： Bryan J. Mealy Electrical Engineering Department Computer Engineering Program California Polytechnic State University San Louis Obispo CA USA

The flexibility of programmable logic devices (PLDs) and their supporting CAD (computer aided design) tools make PLDs ideal for digital systems design courses. This paper outlines a computer design-based course and supporting laboratory targeted for students with intermediate-level digital design skills. The unifying theme of this course is the design, implementation, and programming of a relatively complex microcontroller (MCU). This course emphasizes the development and subsequent integration of basic individual computer building blocks using a hardware description language (HDL). The major topics in the course include finite state machine (FSM) design, computer system architecture, and assembly language programming. Placing emphasis on a hierarchical design approach and ensuring continuity in the course topics reduces potential difficulties in presenting this scope of topics

Annual Northeast Bioengineering Conference

作者： E. Chabot J. DiCecco Ying Sun Biomedical Engeering Program Department of Electrical and Computer Engineering University of Rhode Island Kingston RI USA

The Cricket Car is a remote control car that uses electromyographic (EMG) signals to drive the car. Electrodes are inserted into the legs of the common field cricket and the myoelectric signal, also known as a motor action signal, is amplified. This amplified signal is then acquired by the PIC16F88 processor. Using threshold detection and conditional logic algorithms, the PIC processor sends command signals to the circuit of a remote control car. Features such as object/collision detection, cricket stimulus, and additional signal processing algorithms have been studied and developed. The project has been incorporated into a neuroengineering course. Continuation of this project by undergraduate and graduate students will serve as the impetus for further improvements.

Selecting optimum communication technology for a distributed workgroup such as an electric supply cooperative with a number of sub-stations is a challenge. A quantitative approach to evaluate the various communication technologies based on multicriteria is needed to select optimum communication technology. An electric cooperative in Minnesota was used for a case study and the various communication technologies used (frame relay, fiber optic etc) were investigated. Analytical Hierarchy Process for multicriterion was used to select optimum communication technologies between the sub-stations. The analysis showed that for sub-stations within 10 miles of the hub fiber optic was the most preferred form of communication technology. For distances over 10 miles satellite system was the preferred communication technology. Selection of appropriate communication technology improves the efficiency of the distributed workgroup. Substantial savings in communication costs can be achieved by optimizing the communication technology system.

The Wireless Integrated MicroSystems (WIMS) engineering Research Center (ERC) has developed a broad comprehensive MEMS and microsystem curriculum suitable for upper-level undergraduate students, graduate students, and industry professionals. Five core courses were in the initial curriculum design. The design had flexibility that invited development of other core courses, as well as related technical electives and breadth electives. The core courses provide instruction in MEMS, Microsystems, major design and laboratory measurements, and societal impact. The course enrollments have been strong. A master of engineering in integrated microsystems degree program was developed so that industry professionals would have a focused set of coursework, while providing flexibility that would permit custom tailoring of the total course package to serve specific needs. Distance education dissemination of the courses as whole courses, or as discrete portions of course materials, was intended to be available;that goal has been realized. The core courses originate at the University of Michigan (UM), and have been distributed to Michigan State University (MSU), Michigan Technological University (MTU), Howard University (HU), University of Puerto Rico - Mayaguez (UPRM), and Western Michigan University (WMU). Rochester Institute of Technology (RIT) has used materials from the UM core courses in its offerings. Other institutions that have used the course web-streaming video and course materials are University of Lille, Darmstadt University, and Middle East Technical University. © American Society for engineering Education, 2006.

A Novel 1.5 $^primeprime$ Quadruple Antenna for Tri-Band GPS Applications

引用

IEEE Antennas and Wireless Propagation Letters 2006年 5卷 224-227页

作者： Y. Zhou S. Koulouridis G. Kiziltas J. L. Volakis Electroscience Laboratory Electrical and Computer Engineering Department Ohio State Uinversity Columbus OH USA Mechatronics Program of the Faculty of Engineering and Natural Sciences Sabanci University Istanbul Turkey

A new global positioning system (GPS) antenna is proposed to cover the three GPS bands (L1, L2, and L5, namely 1575, 1227, and 1176 MHz) with the L5 band to be added after 2006. The developed antenna size is only $1.5^primeprimetimes 1.5^primeprime$ in aperture corresponding to $lambda/7timeslambda/7$ $(lambda=hboxfree hboxspace hboxwavelength)$ and $lambda/13 hboxthick$. Quadrature feeding is employed to ensure right-hand circular polarized (RHCP) radiation. The final miniature antenna exhibits a gain greater than 2 dBi, and to our knowledge this is the smallest such size for circular polarized (CP) operation covering all three bands. Detailed parametric simulations leading to the best design along with measurements for the constructed antenna are presented.

Neural prostheses have received considerable attention due to their potential to dramatically improve the quality of life of severely disabled patients. Cortically-controlled prostheses are able to translate neural activity from cerebral cortex into control signals for guiding computer cursors or prosthetic limbs. Non-invasive and invasive electrode techniques can be used to measure neural activity, with the latter promising considerably higher levels of performance and therefore functionality to patients. We review here some of our recent experimental and computational work aimed at establishing a principled design methodology to increase electrodebased cortical prosthesis performance to near theoretical limits. Studies discussed include translating unprecedentedly brief periods of "plan" activity into high information rate (6.5 bits/s) control signals, improving decode algorithms and optimizing visual target locations for further performance increases, and recording from chronically implanted arrays in freely behaving monkeys to characterize neuron stability. Taken together, these results should substantially increase the clinical viability of cortical prostheses. © 2006 IEEE.

We present the use of the polysaccharide chitosan for immobilizing biomolecules on microfabricated device surfaces. The main advantages of chitosan are its abundance of primary amine groups and its ability to be electrodeposited. Biomolecules are easily attached to chitosan's amines by standard glutaraldehyde chemistry. The electrodeposition of chitosan allows accurate spatial and temporal control of biomolecule placement. We have demonstrated this biofunctionalization method for two different BioMEMS devices: a biophotonic sensor and a micromechanical biosensor. We have successfully assembled probe DNA on each of them and detected hybridization with target DNA as a demonstration of sensor operation. Here, we briefly present the fabrication procedure and testing results for both of these BioMEMS sensing devices. © 2006 IEEE.

The use of technology in the classroom has been a driving force behind developing a technically literate society. Reform documents such as Science for All Americans: Project 2061[1], Benchmarks for Scientific Literacy[2]and the National Science Education Standards [NSES][3]include sections titled, Science and Technology and The Nature of Technology, as a means to foster technical literacy for students in grades K-12. In NSES, the goal of the Science and Technology content standard is for all students to develop "abilities of technological design and understanding about science and technology." These reform documents have been the framework to foster science, technical and engineering literacy for students in grades K-12 across the United States as guided by their state science frameworks, however are states achieving this goal? Although these documents promote the need for understanding technology as it applies to science, how have states incorporated these principles into their own science curriculum standards? This investigation is part 2 of a multi-series project to understanding how public schools are training students to become technically literate. In part 1 presented at the 2005 ASEE Conference, we defined technical literacy to be "the ability of an individual to make informed decisions based upon an evolving understanding of the fundamentals of modern technologies." To accomplish this goal, we proposed the engineering Education Frameworks[5](EEF), which defined a pathway toward technical literacy for high school students. It was our intent to develop this set of guidelines to address technical literacy for secondary public schools. These Frameworks were designed to facilitate and promote the simultaneous teaching of multiple science disciplines in concert with mathematics while incorporating engineering concepts and designs. In part 2 of this project, we explore how various states in the United States include aspects of EEF in their science state frameworks
