Automatic Acoustic Water Bottle Filling Station (ECE/ME Joint Project) Nathan Behymer, Ahmed Bohamad, Alberto Gomez-Flores, Lydia Keaty, Nguyen Pham, Erick Pompa, Ivan Santana, Stephanie Suarez, Mohamad Zeidan

The objective of this project is to design, fabricate and demonstrate a water bottle refilling station that elminates water spillage normally encountered with traditional stations. The station employs an infrared sensor to detect a bottle, along with a microphone that detects a predetermined rate of change in the cavity resonance frequencies providing key information on when the bottle is full. Once the signal is detected indicating a full bottle, a microcontroller automatically shuts off the flow of water thus preventing overflow.

Carbon Particle Generator Ali Alqattan, Ricardo Camacho, Cesar Telles, Edward Tomassone, Brandt Walton

Currently, carbon particle generators use gaseous fuels like methane which are not as efficient as liquid fuels such as decane in generating carbon microparticles for solar energy absorption. Our project will utilize a laminar flame burner in combination with a pressure chamber to pyrolyze decane into carbon and hydrogen. The carbon that has been generated will be used to increase the efficiency of a solar based power generation system.

De-Icing System for Composite Leading Edges Sarah Corduan, Prince Glick, Aldo E. Quintana, Mario Vazquez Garcia

Ice-formation on the leading edges of an aircraft is an issue that affects the aerospace industry. Recently, there has been an increased usage of composite structures, but the thermal limits of these materials are much lower relative to more traditional aluminum structures. Therefore, a reliable means for removing ice formation is needed. This system includes heating wires embedded in the composite layers with the addition of expanded graphite to the epoxy matrix in order to increase its thermal conductivity.

Dexcom Sensor Connection Process Feasibility Brandon Cerezo, Mitchell Myers, Felipe Sales, David Jerome Valentin

The production of sensors is a tricky process that can have a low overall efficiency. There are three key factors when using an Anisotropic Conductive Film to bond sensors and wires; the temperature, time, and pressure. The new design allows for accurate pressure readings with a force sensitive resistor and precise temperature control with a thermal insertion heater. The design will allow the user to determine the best bonding conditions and increase the overall efficiency of the process.

Portable Ramps for Curbs Edward Gonzalez-Sainz, Matthew Jensen, Paul Alex Trees, Antonio Vargas

Homeowners with more than one vehicle often don’t have a second driveway for their vehicles and this requires the use of portable curb ramps. However, traditional portable curb ramps are impractical, lack versatility, are heavy, and require continuous assembly and disassembly for every use. The objective of this project is to design, fabricate, test, and implement a new portable ramp system with capabilities to support a large RV that solves all the issues previously discussed.

Power Production Using Thermally Infused Ram Pump Grant Jung, Kenzo Maetani, Cash McCormick, Jesse Richard, Max Umland

The hydraulic ram pump, also known as a “hydram,” is a water pump that uses no electricity and converts a source of water from high flow and low head to low flow and high head. Using pressure surges caused by the water hammer effect, these pumps can continuously pump a portion of their incoming water to a much higher elevation. Team RamPo explored the possibilities of using a modified hydram with a thermally infused pressure chamber to generate electricity by running the exit flow through a turbine setup.

The SDSU Design Studio (EIS-106B) Air Filtration System Yasmeen Alshiyokh, Alex Bogardus, Justin Escoto, Isaac Diaz

The current problem is that the ventilation in the EIS-106B lab needs much improvement to provide quality air flow and exchange. As it continues to be affected with the toxicity that is produced when running the laser cutting machine, 3D printer, and other tools. In response, an HVAC system is to be implemented inside the room to filter all toxic chemicals that flow within the room.
The team was required to study the current system, to improve the filtration, and the air exchange through design recovery.

Solar Sterilization System Spencer Bravo, Cynthia Frausto, James Reece, Alexander Smith, Gardenia Valenzuela 

Access to a cheap, effective, and easily manufacturable system to sterilize medical equipment would help reduce the inequitable occurrence and severity of Health Care Associated Infections (HCAI) in non-standard medical environments, such as those in developing nations and remote military deployments. To remain accessible, it was developed with a minimal number of components that are unavailable or difficult to manufacture in developing nations. Additionally, the system does not require medical consumables to operate.

USAF Windproof Trash Can David Arushanyan, Hector Cea, Jacob Hoppe, Collin Vizina

Trash cans are not typically built to stand in high wind conditions, causing them to knock over and spill out all the garbage into the environment. The high winds at Ellsworth AFB knock the bins over and spread the trash across the base. Not only is the trash unsightly, it also has the potential to damage the aircraft on base.
The lids of the trash cans need to stay secured when tipped over in high wind conditions, but should also be user friendly for the refuse company to dump the trash out.
