Item Bluetooth in Android & Netduino(2017-05-02) Libby, Rachael R.; Pash, PhilThis is the senior design portfollio for Rachael R. Libby, CPET student at IUPUI. The project is to create a lab or two for the ECET434 class that will emphasize the students learning of the Android and Netduino environments while introducing the student to RF/serial communication between devices utilizing Bluetooth.Item An integrated sensor system for early fall detection(2013-05) Bandi, Ajay Kumar; Rizkalla, Maher E.; Salama, Paul; Kim, Dongsoo StephenPhysical activity monitoring using wearable sensors give valuable information about patient's neuro activities. Fall among ages of 60 and older in US is a leading cause for injury-related health issues and present serious concern in the public health care sector. If the emergency treatments are not on time, these injuries may result in disability, paralysis, or even death. In this work, we present an approach that early detect fall occurrences. Low power capacitive accelerometers incorporated with microcontroller processing units were utilized to early detect accurate information about fall events. Decision tree algorithms were implemented to set thresholds for data acquired from accelerometers. Data is then verified against their thresholds and the data acquisition decision unit makes the decision to save patients from fall occurrences. Daily activities are logged on an onboard memory chip with Bluetooth option to transfer the data wirelessly to mobile devices. In this work, a system prototype based on neurosignal activities was built and tested against seven different daily human activities for the sake of differentiating between fall and non-fall detection. The developed system features low power, high speed, and high reliability. Eventually, this study will lead to wearable fall detection system that serves important need within the health care sector. In this work Inter-Integrated Circuit (I2C) protocol is used to communicate between the accelerometers and the embedded control system. The data transfer from the Microcontroller unit to the mobile device or laptop is done using Bluetooth technology.Item Integration of UAVs with Real Time Operating Systems using UAVCAN(IEEE, 2019-10) Ravi, Niranjan; El-Sharkawy, Mohamed; Electrical and Computer Engineering, School of Engineering and TechnologyIn todays world, the applications of Unmanned Aerial Vehicle (UAV) systems are leaping by extending their scope from military applications on to commercial and medical sectors as well. Owing to this commercialization, the necessity to append external hardware with UAV systems becomes inevitable. This external hardware could aid in enabling wireless data transfer between the UAV system and remote Wireless Sensor Networks (WSN) using low powered architecture like Thread, BLE (Bluetooth Low Energy). The data is being transmitted from the flight controller to the ground control station using MAVLink (Micro Air Vehicle Link) protocol. The ideal aim of this research is to address the issues of integrating different hardware with the flight controller of the UAV system using a light-weight protocol called UAVCAN. This approach would result in reduced wiring and would harness the problem of integrating multiple systems to UAV.Item Senior Design Project Report Whole House Ventilation System(2023-05) Rios-Jauregui, Anthony; Herrera Sandoval, Jennifer; Chaiyasit, Matt; Weissbach, Robert; Lin, William; Goodman, DavidThe Whole House Ventilation System was created out of the sponsor’s need to have cleaner air within their home. The system will accommodate a Ranch-style, 2000 sq ft home located in Indianapolis. A microcontroller will be used to control the fan speed and make decisions based on sensor data. Other specifications include having the fan produce noise below 65 dB, physical controls for fan speed and power, and having an Android app to view sensor data. The four system tests we conducted verified power, sensor functionality, and Auto/Manual functionality. All four tests passed. The final system met the majority of the customer’s needs. We recommend a PCB board reprint as some holes do not have pads.
