ABSTRACT: Collar for Hearing Impaired Dogs

Inventive Design

PROJECT DESIGNER: Jason Williams

Dogs with hearing loss are not an uncommon thing. Most dog owners have found ways to communicate with their dogs, and a customer wanted to create something universal that anyone could use. So, the customer came up with the idea of a collar and needed someone to design it. It is designed almost like a shock collar, but it does not shock the dog. Instead, it vibrates with the owner’s voice. After talking to a couple of local vets’ questions were asked. The vets wondered if it would come as more of a surprise to the dog and scare them. One vet asked how the collar would distinguish the owner’s voice versus other noises or even just the owner talking to someone, and another vet brought up the many different sizes of dogs. So, with those questions in mind, a collar was designed that loops to itself. Depending on the dog’s size, it comes in one large size and can be cut down to whatever size is needed. The collar supports many features. The main feature of the collar is that the owner can program their voice just to say the dog’s name or give commands. After considering the research, the final modifications were made to the collar to make it more functional and have better uses. These settings and functions should make the collar for hearing-impaired dogs successful. In conclusion, despite some doubts, this collar was designed to work properly and be a successful invention.

ABSTRACT: Nose Cone Aerospace Testing Structural

Client: Keith Davis

PROJECT DESIGNERS: Gabe Sanchez(PM), Michael Tilson, and Spenser Willard

Did you ever wonder how a Rocket can withstand massive amounts of pressure to launch properly? The secret to its structural strength lies in the isogrid that wraps around the inside of the rocket. What is an isogrid? An isogrid is a stiff, hollow, triangular pattern that lends strength to whatever structure it is built into. These hollow grids also allow for instruments and other electronic pieces to be wired into the structure. For future Aerospace students, learning how to place these electronics and wire harnesses is no easy feat, especially if you are unable to practice on parts that look like the real thing. Luckily for the Aerospace program, their instructor reached out to the Advanced Manufacturing program and requested that such a part be made for his students to work on. This design will have a sturdy isogrid feature built into a shelled-out barrel that mimics the internal structure of an actual rocket. In addition to this, the Nosecone will act as a conversation display piece for outreach programs to local schools to build interest in the Aerospace program. The Nosecone itself will need to be sturdy enough to handle the machining that the Aerospace program will inflict upon the isogrid to fit shelving and wire harness components and sleek enough to be moved around as a display. This project will deliver a two-foot by two-foot Nosecone with the required files to reproduce the piece in the future as needed.

ABSTRACT: 3U CubeSat

Client: Wayne MCCain – Athens University

PROJECT DESIGNERS: Ryan Frost (PM) William Smigel, Brandi Wheeler,

Did you ever think about the last unexplored window of space, the collection of LF and VLF radio frequencies? CubeSats, Cube Satellites are relatively inexpensive small satellites that provide university researchers, Science, Technology, Engineering, and Math (STEM) organizations throughout the education system and associations that research with the opportunity to research space. These CubeSats range in size based upon a single, 1U cube 4″ x 4″ x 4″ that are combined into larger CubeSats (3U, 4U, 6U, etc.) The CubeSats get rides into space aboard a launch vehicle (rocket) and are deployed from that vehicle. The American Institute of Aeronautics and Astronautics (AIAA), Athens State Student Branch, and the Society of Amateur Radio Astronomers (SARA) have joined together in a “Radio Astronomy CubeSat for STEM project to study. This is considered “The Last Unexplored Spectral Window” of space, where long-wavelength radio waves are blocked by the earth’s atmosphere. The development of this current STEM-focused CubeSat will allow the collection of very low-frequency radio waves from outside of the earth’s atmosphere to be transmitted to the earth’s surface. Currently, this is the only known CubeSat to attempt this particular exploration.

Eliminating existing issues with current designs include total weight, cost of manufacture, and burn wire success for the deployment of solar panels. This design addresses each of these issues. The design houses electronic boards to capture low-frequency (LF) signals and send high-frequency (HF) signals back to earth. The CubeSat has ferrite core antennas to receive the LF signals and deployed antennas to send the HF signals. Solar panels provide power to the lithium battery power to operate the CubeSat. The expectation is this CubeSat design will be used for many CubeSat projects in the future, continuing the research to learn more about space.

ABSTRACT: A Lake House Fit for a Dean

Client: Dean John Holley

PROJECT DESIGNERS: Philip Lowery (PM), Chelsea Duford

Imagine waking up to the beautiful views of a pristine lake; the sun is shining through large windows that adorn the front of a quint lake home nestled in the middle of two spacious lots. This home makes every effort to impress with its full kitchen, dining area overlooking the lake, and a large primary suit. However, it was not easy to design such a stunning home with all the amenities while staying within a maximum of 895 square feet. We also faced an issue while designing the layout of the stairs. At first, the stair placement did not allow for a symmetrical look of windows across the home’s lakeside; however, moving the stairs back towards the bedroom quickly remedied the stair’s design problem. In addition, moving the stairs made additional wall space for more floor-to-ceiling windows. By the end of the design process, the total square footage exceeded the clients’ desired square footage by five feet to have adequate space for a laundry room on the main floor. By slightly going over the client’s desired square footage, the design fit the space requirements precisely to what the client wanted.

ABSTRACT: A Forever Home

Client: Dean John Holley

TEAM MEMBERS: Frankey Cunningham (PM), William Hall, Angel Rubio Gutierrez

Have you ever dreamed of having a cozy getaway to relax and entertain, as well as take you through the retirement years? This property, located in Arley, Alabama, off the shoreline of Smith Lake, is the perfect

carefree escape from the stress of city life. The design utilizes the natural sloping environment of the site. The 879-square-foot lake house has three bedrooms and two and a half bathrooms, along with loft space on the second floor that takes full advantage of all the outside views. A sculpturally appealing staircase descends to the lower level, where a walkout leads to the spacious back patio. Accompanying this structure is a boathouse with a party deck. The design connects the inside to the outdoors with an open floor plan concept that includes floor-to-ceiling windows. One won’t mind getting up early because sunrise is always so beautiful, no matter the season.
