Lawn Buddy, Jayson Johnston, Andrew Brown, Jacob Maljian

Electrical Engineering

Grass lawns are a common hallmark of the American home. In 2019, a survey from the National Association of Landscape Professionals found that 81% of all Americans owned a lawn [1]. Mowing is a time consuming and costly chore that is part of maintaining a grass lawn. The manual labor in mowing a lawn can exceed 40 hours per year [2]. People commonly incur weekly costs on mowing services to save time. Traditional gas powered mowers are physically demanding and use engines that need routine maintenance. They operate loudly enough that users should be wearing hearing protection and the noise …


Design, Implementation And A Pilot Study Of Mobile Framework For Pedestrian Safety Using Smartphone Sensors, Aawesh Man Shrestha Jan 2018

Design, Implementation And A Pilot Study Of Mobile Framework For Pedestrian Safety Using Smartphone Sensors, Aawesh Man Shrestha

Electronic Theses and Dissertations

Pedestrian distraction from smartphones is a serious social problem that caused an ever increasing number of fatalities especially as virtual reality (VR) games have gained popularity recently. In this thesis, we present the design, implementation, and a pilot study of WiPedCross, a WiFi direct-based pedestrian safety system that senses and evaluates a risk, and alerts accordingly the user to prevent traffic accidents. In order to develop a non-intrusive, accurate, and energy-efficient pedestrian safety system, a number of technical challenges are addressed: to enhance the positioning accuracy of the user for precise risk assessment, a map-matching algorithm based on a Hidden …


Pinpoint: Location Beacon And Tracking, Ezequiel Lopez Iii Jun 2016

Pinpoint: Location Beacon And Tracking, Ezequiel Lopez Iii

Computer Engineering

The purpose of Pinpoint was to create a device that can collect and transmit location information for multiple users on a wireless network. The device would be used to keep track of and communicate with other users nearby. The final design includes a touchscreen display as a graphical user interface (GUI), an XBee RF module for wireless networking, a GPS receiver for location tracking, and a Programmable System on a Chip (PSoC) to control the modules.


Motohud: Intelligent And Safe Navigational Data Presentation For Motorcyclists, Drew Bentz, William Budney Jun 2013

Motohud: Intelligent And Safe Navigational Data Presentation For Motorcyclists, Drew Bentz, William Budney

Computer Engineering

The system uses a GPS (Global Positioning System) sensor, Bluetooth modem, and OLED (organic light-emitting diode) screen to display navigational information to a motorcycle rider. Currently supported navigational information are speed and heading, with a framework in place for future turn-by-turn navigation. The system is powered by a lithium-ion battery pack and controlled by an Arduino Micro. For turn-by-turn navigation, an Android powered smartphone running our Android App is required. Our system aims to reduce safety hazards from having to tilt or move one’s head when trying to view speed on a motorcycle speedometer, which is usually mounted down by …


General Direction Routing Protocol, Sean Michael Lydon Jun 2009

General Direction Routing Protocol, Sean Michael Lydon

Master's Theses

The General Direction Routing Protocol (GDRP) is a Wireless Sensor Network (WSN)

multi-path routing protocol which abstracts localization information (commonly GPS

coordinates) into relative direction information in order to perform routing decisions. By

generating relative direction information GDRP is able to operate with fewer precision

requirements than other protocols. This abstraction also allows the integration of other emerging

hardware-based localization techniques, for example, Beamforming Sensor Arrays.

GDRP does not specifically address the next hop a packet should take, but instead specifies a

direction it should travel. This direction abstraction allows for multiple paths to be taken through

the network thus …
