Object Tracking Through The Use Of Color Hue Image Processing, Zachary R. Sabey
Object Tracking Through The Use Of Color Hue Image Processing, Zachary R. Sabey
Electrical Engineering Undergraduate Honors Theses
Many industrial and commercial applications today are beginning to use autonomous systems to increase productivity and cut costs in production and manpower. Most of these applications are only semi autonomous; they still need assistance from a human to either start up or receive continual instructions. With the improvement of image processing techniques, camera processing capabilities and more efficient vehicles, a new wave of fully autonomous vehicles can be implemented. A simple system that uses a dedicated image processor connected to an RC vehicle can be developed to provide an example for the new techniques currently available. The Pixycam, a dedicated …
Implementation Of Prediction Algorithms To Reduce Latency In Control Of Switching Converters, Brent Bell
Implementation Of Prediction Algorithms To Reduce Latency In Control Of Switching Converters, Brent Bell
Electrical Engineering Undergraduate Honors Theses
Using pulse-width modulation (PWM) to control switching converters such as a dual active bridge introduces latency into a system [1]. Latency in a switching converter decreases the effective bandwidth that the converter can be switched at and for the case of a closed loop control system decreases the effective closed loop system stability. This delay can be attributed to sampling of the control signal and calculation time for the PWM. If a prediction scheme is implemented in this calculation, the next switching time could be predicted to remove any latency. There are effectively two steps in order to achieve this …

Mapping Device With Wireless Communication, Xiangyu Liu
Electrical Engineering Undergraduate Honors Theses
Wireless communication is one of the most powerful communication methods that people use nowadays. The key advantage of wireless communications is that it can cover large distances without having to run any cables from one end to the other. Based on this advantage, wireless communication has many important applications, such as remote controls, cell phones, and global positioning system (GPS). This senior design project is developed to use wireless communication technology to map the geographic characteristics of an unknown place. It contains two wireless communication modules with Atmega1281 microprocessor, two robots with the 8051 microcontroller, six pairs of infrared transmitters …
An Expressive Vocal Midi Controller, Brady Hurlburt
An Expressive Vocal Midi Controller, Brady Hurlburt
Electrical Engineering Undergraduate Honors Theses
The choice of controller often characterizes the performance obtained from an electronic instrument. Controllers exist that allow electronic musicians to mimic the expressive qualities of keyboard, wind, string, and percussion instruments, but vocalists have been largely neglected. To fill this need, a realtime software vocal MIDI controller named Grove is developed and demonstrated. Grove's pitch and time analyses are shown to be accurate, and it has mappable control signals that go beyond the capabilities of previous audio-to-MIDI converters to facilitate an expressive performance. Grove's source code is available under the GNU GPL v3 license.
