Rfid Asset Tracking And Digital Check-Out System, Jeffrey (Jeff) Migliore Jun 2010

Rfid Asset Tracking And Digital Check-Out System, Jeffrey (Jeff) Migliore

Computer Engineering

An asset tracking and digital check-out system was developed using Radio Frequency Identification (RFID) and a Single Board Computer (SBC). A RFID reader was used as a check point to process transactions. The RFID reader was attached to the SBC via USB. The SBC is integrated into a network via Ethernet and hosts a web graphical user interface (GUI) frontend for users to view transactions and query availability of assets. A MYSQL database was used for the backend storage of data.

Specifically, this system was designed to track tool assets. Many modern companies have employees sharing limited resources. The common …


Digital Signaling Processor Resource Management For Small Office Phone Systems, John T. Gilkeson Jun 2010

Digital Signaling Processor Resource Management For Small Office Phone Systems, John T. Gilkeson

Master's Theses

Contemporary small office phone systems are specialized computers that connect a variety of phones within the office and to the local phone company. These systems use digital signaling processors (DSPs) to convert signals from analog to digital and vice-versa. Many different types of applications run on the DSPs and different businesses have varying application needs. Given the systems have limited amounts of DSP resources and growing numbers of applications for a phone system, an administrator needs a way to configure the uses of resources based on their individual business needs.

This thesis provides an overview of a system for configuring …


Touch Screen Sound Controller, James Fenley, Jonathan Law Jun 2010

Touch Screen Sound Controller, James Fenley, Jonathan Law

Electrical Engineering

The Touch Screen Sound Controller sets out to explore the use of a touch screen as a sound control interface for the disk jockey profession. In addition, the project aims to provide an alternate means of transferring audio data by way of TCP/IP communications as opposed to MIDI. By applying our method, a user may stream pulse-code modulated data from a server onto a client’s RAM via an Ethernet connection. A 32bit, 200MHz ARM9 microprocessor addresses data from the RAM and proceeds with executing DSP instructions from the user. The connection between the touch screen and the central microprocessor is …

Pretty Lights, Nicholas (Nick) Delmas, Matthew (Matt) Maniaci

Computer Engineering

Digital media players often include a visualization component that allows a user to watch a visualization synchronized to their music or videos. This project uses the visualization plugin API of an existing media playback program (WinAmp) but it displays its visuals using physical LED lights. Instead of outputting visuals to the computer screen, data is sent over USB to a micro controller that runs the LED lights. This project aims to give users a more visceral visual experience than traditional visualizations on the computer screen.
