Design Optimization of MEMS Comb Accelerometer Kanchan Sharma, Isaac G. Macwan, Linfeng Zhang, Lawrence Hmurcik, Xingguo Xiong Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT 06604 AbstractMEMS (Microelectromechanical Systems) refers to the technology integrating electrical and mechanicalcomponents with feature size of 1~1000 microns. MEMS comb accelerometers have been successfullyapplied for air-bag deployment systems in automobiles. In this paper, the design optimization of a poly-silicon surface-micromachined MEMS comb accelerometer is discussed. The device uses folded-beamstructure to

insufficient figures to illustrate these rules. This paperwill discuss the author’s attempt to address this problem.Force on a spur gearWhen two spur gears are meshed shown in Fig. 1, and the left one is the driver, the contact pointmoves along a line as the gears rotate, as shown in Fig. 2. The line of action is sometimes calledthe pressure line. The force pushing the driven gear is shown in Fig. 3, and will always be alongthis line of action. The type of force is bearing (pushing) force, applying pressure to the matingtooth. From the principal of force transmissibility in statics, we know that any point along theline of action will still create the same torque about the gear. Therefore, we can use a fixedcontact point (pitch point) to simplify the

Groover [1] defines a PLC as: “Amicrocomputer-based controller that uses stored instructions in programmable memory to implementlogic, sequencing, timing, counting, and arithmetic functions, using digital and analog input/output (I/O)modules, for controlling machines and processes.” Although PLC’s are used in the process industries(e.g., processing mined materials and oil refineries), they are more commonly found in discretemanufacturing industries, such as in machine control, transfer lines, and material handling equipment.First conceived in 1968 by Richard Morley, the PLC was originally developed as a device to overcomethe inflexibility and high cost of hard-wired controllers made of

Yet, the first thing we often do when planning a courseis select a textbook. And often one of the first things we are asked about our course is “whattextbook are you using?” Selecting and relying on a single textbook tends to be teacher-centered and content-driven, whereas a learner-centered, outcome-driven approach tocourse design is generally recommended6 and results in more learning2. A more learner-centered, outcome-driven approach is easier today given the availability of digital resourcesand collaborative tools. Page 1 of 10Using

The distribution ischaracterized by type/shape of the dispersed phase particles, size of the particles, as well orientation anddistribution.Distribution of fibers in fiber-reinforced composites is varied as per the application or load to be carried.These types are (1) continuous fiber

Also, we present techniques to limit the nonlinear behavior of N and to eliminate severalkey sources of experimental error. INTRODUCTIONThe conventional way to teach friction is based on several classical concepts, which wereformulated by Amontons and Coulomb [1,2]. These can be summarized by the equation f = μ N.
