What is the advantage of using timing screw for this automatic filling system?2. How much efficiency based on production and cost we can retrieve using timing screw indexing?The purpose of this research was to design an automatic indexing for an industrial liquid fillingsystem which is basically a piston filler system. The automatic indexer was achieved by a timingscrew from “Morrison Container Handling Solutions”, driven by an Allen-Bradley servo motioncontrol system. The system can inspect the desired number of containers to be filled, accept tofeed into the timing screw also perform

In Section IV we present post survey results collectedfrom the students and discuss potential improvements to be implemented in subsequent versionsof the platform. Finally, we present concluding remarks in Section V.II. Platform DesignIn an effort to create a low-cost experimental platform that could be used for multipleengineering courses, we decided to use recycled 0.25 inch plywood to create a reconfigurablebase chassis. The base chassis was designed by a team of 4 members including, 2 students (1undergraduate and 1 Ph.D. student), 1 research associate, and 1 teaching faculty.As part of the design constraints the platform

Container to hold particulate solidsAn Alien RFID reader is used and model number is ALR-9800 (figure 2a). The reader is basedon an Intel XScale processor, along with digital signal processor (DSP) (Roberti, 2006). TheDSP enables the rapid interleaving of different protocols with minimal switching overhead,resulting in fast performance to interrogate RFID tags [10]. Supported RFID tag protocols areECP Class 1 Gen 2, ISO 18000-6c [10]. Alien reader protocol is autonomous mode which hasupgradeable architecture for future EPC reader protocols.

For this research we have used a passive tagmanufactured by Alien Technology®. This Gen 2 has been used throughout the whole experiment.(Take a picture of the RFID TAG)Again, the RFID reader used to perform the experiment is also manufactured by AlienTechnology®.

TheLabVIEW runtime window indicates the progress of the measurement time with a highlightedhorizontal bar graph display and plots the drain I-V characteristics of the device in real time as thedata is gathered. At the conclusion of the measurement an Excel compatible file is created forfurther evaluation, interpretation, graphing of the data, and for SPICE parameter extraction [1].Power MOSFET devices, to measure their I-V characteristics under a PC’s control, require apower supply with a minimum of two channels which can be controlled by a PC via a serial, or aGPIB, or a USB interface.

biomedical instrumentation uses electronic sensors, analogand digital circuits, computers and microcontrollers for scientific measurements and processcontrol. Instrumentation is used widely for commercial product development, testing, and basicresearch. The course described in this paper introduces basic measurement theory, applications ofinstrumentation and controls along with features of basic biological, environmental, andmechanical sensors. Sensors and transducers introduced include contact, non-contact, mechanical,thermal, optical, ultrasonic, and other devices.The topic areas of the course given 2015 are presented in Table 1. During the first five weeks, thereis an intensive introduction to the understanding of fundamental instrumentation
environment, orceasing to exist in the near future. Significant progress has been made over the last few years inthe research and development of renewable energy systems such as wind, sea-wave andsolar energy systems. Among these resources, solar energy and wind are considered the mostpromising, reliable, abundant, and environment friendly renewable energy source [1, 2]. Most ofthese energies are dependent on parameters such as time of the day, presence of sun or speed ofthe wind. The energy production from these resources will be drastically affected as theseparameters change. Storage systems such as battery banks are utilized to store the surplus of theproduced energy from these renewable sources. Energy storage then becomes an essentialcomponent

In previous work we developed labs using ROS and Moveit to teach basicKinematic concepts in robotics [3]. The previous work only used simulated robot arms to teachconcepts in robotics. The obvious next step for us was to add a real robot arm to the lab configuration.We have worked with well over a hundred students at the high school level and a small number at thecollege level successfully building robot arms similar to the one shown in this paper. The robot armused RC servo motors to drive the robot arm joints. The robot arm was controlled in
mounted to aircraft components and acted upon by a force. The real-time signals,received from strain gages, will be in turn transferred to LabVIEW software program in order tocalculate and plot strain and stress values. Comparing the relationship of the stress and straindistribution curves proves the effectiveness of the experiment.TheoryIn order to simulate this process, the theory of pure bending will be utilized to obtain engineeringstrain values from a specimen under a specific load. Pure bending will allow a section of thespecimen to undergo a constant bending moment, due to the absence of shear forces within thespecific section. Figure 1 shows a specimen in pure bending set up, as well as the associatedshear and moment diagrams4. As

Background A key driving force in the development of robotic systems is their potential for reducing the need of human presence in dangerous work environments. The nature of any of these challenging work environments require that such robotic systems be able to work fully and accurately in achieving human supplied goal [1, 2].

engineering class,“Computing Tools for Engineering Design”, where lectures were available to all students bothin-person and as a video recording of the same lecture. On exams and quizzes each student wasasked how they prepared for each test: did they prepare by use of in-person lectures, onlinelectures, a combination of both or neither? We then compared how each method of coursedelivery used by a student with the resulting grade on the quiz/exam. This information was usedto determine if the mode of lecture delivery (in-class or online) impacted students’ performanceon examinations.1. IntroductionAlthough distance learning and video lectures have been available for the past 50 years (e.g.,Open University1), recent advances in video and online
industrial partners neededmore pneumatics and PLC control than local manufacturing employers in the steel, automotive,and rail industries. The principles of pneumatics and control of pneumatic circuits lends itselfparticularly well to productive laboratory experiences in an instrumentation & control ormechatronics context to serve as a first introduction to PLC control.Pneumatic actuators and solenoid valves are relatively inexpensive and can provide fast motionthat catches the eye in lab when incorporated into an appropriate trainer. However commercialpneumatics trainers or PLC trainers are expensive and limited in what they can demonstrate. Fig. 1 Final 80/20 Cart without Components InstalledWe have prototyped a PLC
called micro-nets. The main purpose ofthe project is to monitor a mountainous ecosystem in three dimensions. To achieve this, themicro-nets are spatially distributed from top to bottom on the mountain, and from the top to thebottom of 25 meter trees. This identifies the ecosystem by major elevation and by layers offorest canopy.The project goals are as follows:1 1) To achieve real time wireless three dimensional monitoring of a mountainous ecosystem. 2) To comply with all the minimum impact requirements in the Wilderness Act of 1964. 3) To make the system autonomous, requiring maintenance at most once per year. 4) To physically install the system and have it functioning within one year. 5) To maintain sensors within industry
