    Design and Implementation of Energy Usage Monitoring and Control Systems Using Modular IIOT Framework
    (2021-05) Chheta, Monil Vallabhbhai; Chien, Stanley Yung-Ping; Chen, Jie; Li, Lingxi
    This project aims to develop a cloud-based platform that integrates sensors with business intelligence for real-time energy management at the plant level. It provides facility managers, an energy management platform that allows them to monitor equipment and plant-level energy consumption remotely, receive a warning, identify energy loss due to malfunction, present options with quantifiable effects for decision-making, and take actions, and assess the outcomes. The objectives consist of: 1. Developing a generic platform for the monitoring energy consumption of industrial equipment using sensors 2. Control the connected equipment using an actuator 3. Integrating hardware, cloud, and application algorithms into the platform 4. Validating the system using an Energy Consumption Forecast scenario A Demo station was created for testing the system. The demo station consists of equip- ment such as air compressor, motor and light bulb. The current usage of these equipment is measured using current sensors. Apart from current sensors, temperature sensor, pres- sure sensor and CO2 sensor were also used. Current consumption of these equipment was measured over a couple of days. The control system was tested randomly by turning on equipment at random times. Turning on the equipment resulted in current consumption which ensured that the system is running. Thus, the system worked as expected and user could monitor and control the connected equipment remotely.

    Monitoring 3D Printer Performance using Internet of Things (IoT) Application
    (2017-06-24) Li, Shuning; Freije, Elizabeth; P.e, Paul Yearling; Mechanical Engineering, School of Engineering and Technology
    Most of the current desktop 3D printers are built based on open-source designs from online communities. The largest group of open-source 3D printers is the Self-Replicating Rapid Prototype (RepRap) 3D printers. A RepRap 3D printer needs to connect to a computer or a microprocessor to feed G Code and provide interface for users to control the 3D printer. However, local computer is a relatively expensive solution comparing to the cost of a RepRap 3D printer; while the microprocessor has much less computing capability comparing to a normal computer, and cannot handle computing-intensive jobs like slicing 3D objects or generating G Code. An alternate solution is to use the internet of things (IoT) application to control and monitor 3D printers. IoT is the network of physical devices, vehicles, buildings and other items, allowing objects to be sensed and controlled remotely across existing network. IoT and 3D printing are two important new technologies, which progressively impact a lot of areas of the industries and also our everyday life. Students need to be introduced to these technologies, and get ready for future career opportunities. A multidisciplinary student project is developed to provide students access to both 3D printer and IoT platform, and also learn to collaborate with engineers from other disciplines to solve complex engineering problems. The objective of the project is to design and develop an IoT application to remote monitor the performance of a RepRap 3D printer including the printing progress and the temperatures of the heated bed and hot end. Major tasks involved in the project are: to inspect and upgrade the current 3D printer to avoid any possible compliance issues between the 3D printer and the hardware components or software tools for the IoT application; to connect the 3D printer to the Raspberry Pi microprocessor; and to design and develop the IoT application. The methods and algorithms of connecting a 3D printer to an IoT application is reported, and the IoT application interface and workflow will be presented in the results section. As a pilot study, this project provides first-hand data on the requirements of time and resources to introduce IoT to undergraduate students.

    The Privacy, Security and Discoverability of Data on Wearable Health Devices: Fitness or Folly?
    (2017-07-12) Kumari, Vishakha; Hook, Sara Anne
    With data from wearable health devices increasing at a rapid rate, it is important for lawmakers to make sure that this data remains well protected. This paper will question the perceptions of people with respect to current and future use of wear-able health devices, especially if the security and privacy risks to their data are more commonly understood, and particularly if this data is discoverable and ad-missible in court. It will explore the electronic discovery issues with data from wearable health devices in the context of litigation and examine how the current rules of court procedure and evidence would be applied. The paper will review the federal and state legislation that may or may not provide protection for data from wearable health devices. The authors intend to use their paper as a vehicle to advocate for stronger statutory protection and greater clarity about the use of and potential risks to this data, including when the data becomes evidence in liti-gation.
