SHOCK CIRCUIT FOR VIRTUAL FENCE SYSTEM

Ranchers spend valuable resources constructing and maintaining fences to control the grazing boundaries of their cattle operations. As these fences are time consuming and difficult to build, the flexibility of the grazing area is lacking. This harms the landscape and decreases livestock production. There is a need for an adaptable system that can control the grazing area borders. A virtual fence system can be remotely operated, allowing ranchers to easily implement rotational grazing systems.

ELECTROLYSIS FOR SUSTAINABLE GENERATION

Sodium sulfate is produced as a by-product in several chemical processes, including the water recovery plant at Freeport-McMoRan Inc. (FMI).

Sodium sulfate has many applications, but an economically viable product cannot currently be produced by FMI, resulting in their sodium sulfate being transported as waste to a landfill. The WERC team aims to utilize electrolysis to produce and recycle sulfuric acid back to the FMI plant and, in turn, reduce waste production and transportation fees.

SHOCK CIRCUIT FOR VIRTUAL FENCE SYSTEM

BACKGROUND

• Multiple team project

o Engineering

o Animal

o Stakeholders

• Current Design is too heavy and consumes too much power

• Current design is based on shock collars and electric fence systems

VALUE PROPOSITION

Ranchers spend valuable resources constructing and maintaining fences to control the grazing boundaries of their cattle operations. As these fences are time consuming and difficult to build, the flexibility of the grazing area is lacking. This harms the landscape and decreases livestock production. There is a need for an adaptable system that can control the grazing area borders. A virtual fence system can be remotely operated, allowing ranchers to easily implement rotational grazing systems.

KEY REQUIREMENTS

• To construct a variable shock circuit

• Circuit shall provide feedback after shock is delivered

• Circuit should weigh no more than 15 grams

• System shall fit within a 250 x 100 x 300 mm enclosure

• Circuit is compatible with existing PCB design

CONCEPT DEVELOPMENT

THE FINAL DESIGN GHOST COWBOYS

VALIDATION

• Use cow ear to determine impedance and optimal frequency

• Test variability of shock using oscilloscope and ammeter Instructor: Dr. Russell Qualls Sponsor: Dr. Dev Shrestha

• Weigh finished circuit to ensure it’s less than 15 grams

• Test for feedback on successful shock delivery through current sensor feedback

CONCLUSIONS & RECOMMENDATIONS

• Use an ideal frequency of 1000 Hz

• Transformer – Increase voltage to target range

• Current sensor – Provide feedback on shock delivery

• Gate Driver – Arduino to MOSFET current amplifier

• MOSFET – DC to AC switching

• Diode – Protect components from high voltages

• Use in vivo probes to allow minimal resistance

• Integrate shock circuit into current design

• Test on live cows to find ideal shock values

ACKNOWLEDGEMENTS

We would like to thank Yuan Yuan, Hope De Avila, Karen Launchbaugh, and Matt Shyrock for their guidance on our project.

OBJECTIVE

Tendon is a tissue in our body that attaches muscle to bone, playing a key role in force transfer and movement. Tendon has poor healing capabilities, making it a vital area to research for health.

Our goal is to create a low-cost, easily built bioreactor capable of mimicking human body conditions to aid in tendon cell study.

CELL RESPONSE

Team Members: Benjamin Morenas, Ishmael Staples, Carson Sloan, Carson Rueber, Chris Bui, Guo Zhonghao

Team Sponsors: Joe Stanley, Nathan Schiele Lead Instructor: Russell Qualls Team Mentor: Yuan Yuan

SYSTEM

The flow rate through the bioreactor is primarily controlled by varying the pump speed. Peristaltic pumps cause oscillations in the flow, which is mitigated by a pulsation damper device at low flow rates. At high flow rates, needle valves are used to precisely control the main and bypass lines based on measurements from two high-precision flow sensors.

Oscillations are mainly caused by the pump rollers squeezing the tubing and are proportional to the flow rate.

The program calculates the shear stress experienced by the cells based on the flow rate and bioreactor channel dimensions.

The

SOFTWARE INTEGRATION

The interface, powered by an ESP32, provides advanced control of the bioreactor and connection to Wi-Fi networks to enable real-time data transmission for visualization.

The bioreactor is controlled by connecting directly to the ESP32, while data can be visualized at thingspeak.com, from anywhere, any time.

REQUIREMENTS

• Long-term experiments with 0-150 mPa shear stress

• Short-term experiments with 1-2 Pa shear stress

• Flow applied to cells must be laminar

• Parts must be easy to clean

• Less than $1500 worth of easy-to-get parts

• Easy to use interface for creating experiment protocols

• Remotely visualize system status

CONCLUSIONS

The bioreactor meets most of the requirements listed above in short test cases, including meeting the target flow rates, applying laminar flow to cells, and being able to control and visualize data, all while remaining within our budget.

Future work would include upgrading the peristaltic pump and performing more multi-week testing with cells in the system to make sure it can run for long periods with highly accurate flow and shear rates. Since every part is replaceable, future users can customize the design with different parts if they want. Doing this is recommended, as there may be better options not utilized here that could provide an advantage in precision or ease-of-use.

OBJECTIVE

Automate alignment of an optical receiver to a laser source, based on the measured light intensity at different positions. Reach optimal alignment by achieving maximum intensity.

BACKGROUND

Hansen Photonics Inc. is a small, family company located in Burien, Washington. They contribute to the computer networking industry with patents that cover modular networking hardware devices and systems. HPI works with universities, environmental science centers, and small businesses to help provide new, cutting-edge hardware solutions for everyone.

VALUE PROPOSITION

Optical transfer allows for greater data transfer capacity than electrically. It can be implemented in a cost effective and environmentally friendly way via lasers. This requires very precise alignment between two devices, potentially taking hours of labor to establish a connection. Automating the alignment with software provides significant convenience.

KEY REQUIREMENTS

1. This alignment process shall work at a minimum distance of 6 feet.

2. After program is started, the alignment process is fully automatic.

3. The finished device weighs less than 10 lbs.

4. The program is written in a modular, scalable style.

INTENSITY-BASED ALIGNMENT OF LASER DEVICES

Developed By: Track Tech

Dawson Burgess, Spencer Butler, Marissa Samayoa

Lead Instructor: Bruce Bolden

Client: JP Hansen – Hansen Photonics

CONCEPTUAL DEVELOPMENT

Design software for alignment of laser devices via optical intensity.

Language: Arduino C++

Environments: VS Code Platform IO

FINAL DESIGN

Final Process:

1. Find the brightest position along the R-axis, corresponding to the angle towards the broad light source.

2. Switch the light sensor to lowest gain, to support measuring the laser, which is very bright.

3. Alternate between optimizing along the X, Y, and R axes, searching for the brightest point upon each.

4. Continue until reaching a point where the measured value is sufficiently large.

CONCLUSION VALIDATION

1. Alignment worked at 6 feet.

2. Alignment worked at minor offset angles, as well as at 45 and 90 degrees.

3. Transmitter weighs 1.25lbs and receiver weighs 1.06lbs.

4. Alignment does not require user input after beginning the process.

The alignment process created meets the desired requirements, aligning the laser to the receiver. However, it may take several minutes, and the receiver may stop when reaching the side of the laser rather than the center. Further development could optimize the speed of the alignment or ensure that the receiver always reaches the exact center of the laser.

OBJECTIVE

To design, manufacture, and validate a system to separate metallic uranium from glass and zirconium oxide waste

BACKGROUND

The EBR-II and certain modern advanced nuclear reactor designs produce low level mixed quartz and metallic uranium waste through the production of their fuel. High assay low enriched uranium (HALEU) is extremely expensive and is subject to stringent tracking requirements, necessitating a system to efficiently separate residual uranium for recycle from the quartz waste

Value Proposition

Thisprojectaimedtoinvestigatethedrageffectsofriveted versus smooth aircraft surfaces using oil film interferometry (OFI). Through comprehensive testing, we aimed to provide Kodiak with insightful quantitative data to inform a major manufacturing decision.

OFI Theory

Oil film interferometry (OFI) is a technique used to visualize and quantify thin oil film distribution on surfaces. OFI relies on interference patterns formed by coherent light passing through the oil film, revealing details about film thickness, flow patterns, and surface conditions with exceptional sensitivity. OFI offers advantages such as non-intrusiveness

Airfoil Validation

Results

80% Increase in Coefficient of Drag when Rivets are Introduced OFI Testing

Oil Applicator Design

The oil applicator is 3d printed using a resin-based process that allows high resolution parts to be manufactured. This was designed to make application of the oil more consistent than previous methods.

Wind Tunnel Setup

1: Manometer

2: Airfoil

3: Wind Tunnel Control Panel

4: Servo Load-Cell Assembly Summary

This project successfully assessed the drag effects of riveted versus smooth aircraft surfaces using oil film interferometry (OFI). The coefficient of drag increased by 80 percent with rivets. Additionally, the oil applicator was developed to enhance the OFI process. This data provides valuable insights for Kodiak's manufacturing decisions, contributing to aerodynamic research and aircraft design optimization.

Flat Plate

Before performing OFI on curved surfaces, a flat plate testing fixture was made tovalidate our testing and post-processing procedures. The flat plate was designed in SolidWorks and then printed in three parts. It houses a polished square of stainless steel which acts as the testing surface.

OBJECTIVE

Determine Economic feasibility of sending wastewater from CNR (College of Natural Resources) to UI Power Plant.

BACKGROUND

The Wet Labs use between 1-4 million gallons of water per month that go to drain. Due to the nature of their work they can’t reuse the water. Our goal to to take this water and redirect it to the UI Power Plant to use in their heating and cooling systems.

VALUE PROPOSITION

• Capture wastewater from the Wet Lab and redirect it to the Steam Plant to use in the heating system and cooling towers. This not only conserves water but also provides a valuable and eco-friendly use for wastewater

KEY REQUIREMENTS

• Fully develop piping system with an economic pipe diameter and pump to overcome elevation change and pressure of 7 psi

• Compute economic analysis to determine total cost of implementation and payback period

• Explore Benefits to campus sustainability

OBJECTIVE

BACKGROUND

To design and manufacture a working prototype that will automate the first two stages of the current assembly process, as well as allow room for modularity to produce a complete machine in the future. Nightforce assembles and packages all riflescope rings by hand and are looking for ways to improve efficiency and operator comfort.

VALUE PROPOSITION

NIGHTFORCE AUTOMATED RING ASSEMBLY MACHINE

KEY REQUIREMENTS CONCEPT DEVELOPMENT

Around $80 billion dollars are lost every year by companies due to workplace injuries attributed to cumulative trauma or overuse. Our design will reduce injuries, improve operator comfort & increase overall efficiency on the assembly floor. No dangerous repetitive tasks required for operators.

Place pic-rail clamp and apply anti-seize to ring base.

Compatibility for current pneumatic and electrical systems at Nightforce.

Modularity for future improvements and operations to be added.

A linear, rotary, and internalrotary automated assembly systems were all developed as early conceptual ideas for our final product. Our final revision of our SolidWorks design utilized a box frame of 80-20 and a locking detent system to allow for modularity and easy alignment of the ring base to each operation.

Nightforce Optics, Grant Minor, Jake Elliott, Ian Novasio, Lead Instructor Matthew Swenson, Graduate Mentor Dan Revard, and Shop Manager Brian Petty Components:

This design allows for easy loading/unloading of ring bases, as well as room for the clamp installation and anti-seize application operations. Being able to install future stages for the remaining operations will be easy and require minimal alterations.

THE FINAL DESIGN

After machining and printing all the necessary parts, our physical prototype was ready to program. We utilized a combination of stepper and servo motors to operate the functions of the clamp installation and run our Python program off a Raspberry Pi controller.

SPECIAL THANKS TO:

SUMMARY

Our prototype succeeded in being a proof-ofconcept for future applications that Nightforce may have for manual tasks that could be automated.

Our prototype also met our key requirements given to us by Nightforce and was able to place clamps onto the ring base as well as apply anti-seize to the crossbolt threads.

RECOMMENDATIONS

Parts that are 3D-printed should be machined to be more durable. The modular fixtures to hold the ring bases will benefit from this if force is required to deform the crossbolt threads in the future.

Instead of a magazine-fed system which requires the operator to load parts, future designs should implement a vibratory bowl feeder to self-align and load parts for complete automation and require less “hands on” attention from operator.
