Two Senior Projects: 2.4 Ghz, 40% Efficiency Radio Frequency Amplifier, Ieee Design Contest, & Design And Implementation Of A Software Costas Loop For Audio Frequencies, Robert J. Tong

Electrical Engineering

How to Read this Document:

This document combines two senior project reports. The first senior project documents designing a class AB RF amplifier. The second, discusses the design and implementation of a software Costas loop for audio frequencies. The first report begins on the next page, while the Costas loop report starts on page 24. The two reports are orthogonal from one another. It is not a prerequisite to read the RF amplifier report before reading the Costas loop report. This document is merely two reports combined into one document. The second report, about the Costas loop, was written as …

Investigation Of Mimo Communications, Rodrigo Mendez Olea, William C. Tran, Patrick C. Kezer, Jean M. Whitmore

Electrical Engineering

This project focuses on the background of multiple input multiple output (MIMO) communication and its advantages over the other possible implementations. A background of wireless communication in regards to modulation types, information theory, antenna background and a hardware implementation using a VSA and VSG is provided. The theory is compared and verified with the hardware implementation with regards to the effect of the increase in the number of antennas and the parameter vector error magnitude.

Hands On, Michael Le, Justin Remulla, Chris Menezes, Noah Beilin

Electrical Engineering

The goal is to design an extremely articulate smart glove, which acts a virtual reality controller. The smart glove will have gesture detection, which could include hand movements and/or combinations of finger movements to emulate mouse click or scroll, or digitally map out a hand for integrations with virtually reality softwares. This glove will have multiple accelerometer sensors on each finger and joint, connected to a single board running BLE MCU SoC in order to communicate with computer or mobile devices. The glove would connect to devices such as computers or phones using a Bluetooth dongle with applications in virtual …

Remote Cable Gantry, Allen L. Bailey

Electrical Engineering

The Remote Cable Gantry is a robotic system that was initially intended to aid in the art of aerial videography. It was designed to enable novice and expert users alike to capture both video footage and audio from perspectives unachievable by current methods. This system uses a series of cables to control the position of a camera gimbal in a defined 3D space and, as a self-contained unit, is portable and easy to use. The Remote Cable Gantry offers a quiet, intuitive, and safe alternative to existing technology, which has been limiting the market and potential of aerial photography and …

Wireless Communication For Greenhouse Environment, Chris J. Lambert, Dean T. Lockman, Ian A. Nielsen

Electrical Engineering

Modern day population growth and global climate change requires high-yield agricultural systems that can function in harsh environments. Greenhouses can maintain temperature and humidity, while serving as a protective, nurturing alternative to vulnerable farm environments. With weather effects eliminated, greenhouses provide productive environments for experimental agriculture techniques such as hydroponics and aquaculture. These methods of agriculture, specifically aquaculture, require constant monitoring. The failure of electronic devices such as an air pump prove fatal to a fish population in a short time frame. In developing countries, agricultural locations may be a significant distance from a farmer’s home, with no internet or …
