Evergreen Goodwill serves its non-profit mission of providing free job training and education to those who face barriers through the process of accepting donated goods, processing those goods (evaluation and pricing), placing those goods in the correct channel (retail stores, outlet stores/salvage, e-commerce) and collecting revenue in exchange for those goods. A significant portion of the net revenue value equation is the time spent processing product. Evergreen Goodwill's current sort process has been in place, with slight modifications, for the past 10-15 years, and is looking for a process to better serve them financially by producing items for quickly and efficiently. The student team worked to create a report to Evergreen Goodwill that outlines affordable and effective production of items, from donations through production, and investigates human and material resources that are significant contributors to gross revenue.

To make the process of testing analog to digital converters (ADC) efficient, the student team designed a flexible ADC testing platform that can assess the performance of different ADCs. The system integrates three different hardware elements: PC, microprocessor, and ADC shield. The system provides a friendly user interface, such that users can adjust ADC parameters and interact directly with different ADC shields.

FSX designs, constructs, and operates machinery used to service diesel exhaust emissions equipment. In particular, FSX cleans diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs). These drum-shaped filters help to greatly reduce the emission of harmful diesel combustion byproducts such as carbon soot, carbon monoxide (CO), and nitrous oxides (NOx). The filters require occasional servicing (cleaning) in order to give optimum fuel economy, reliability, power output, and filtration efficacy. FSX identifies a great number of failed filters, typically defective due to thermal damage allowing exhaust to pass through unfiltered. DPFs and especially DOCs have a small amount of precious metals attached to the filter substrate to act as a catalyst. FSX wants to identify a reliable method of separating those precious metals from the substrate for assay purposes. The student team worked to perform research and experiments to determine a methodology to separate/extract the precious metals.

The maintenance of aircrafts is a critical factor for safe flights. Aircraft technicians need to have a consistent and reliable system that obtains working data about specific aircraft. This student team created an app that generates QR codes that take information from Horizon Air's database on aircraft to be scannable on mobile devices and present technicians in the filed with the information they need to perform aircraft maintenance.

The student team used the capabilities of AI technology to help guide and land a UAV. The team explored the application of DepthAI and object detection to recognize and guide a drone to land on a platform, and successfully modeled a multirotor VTOL vehicle landing on a moving ship with the use of an AI camera.

Data and user activity and trends can help in improving future CPU development. The student team studied and compared the trends of native apps versus web-based apps and their impact on client resource utilization based on user-web activity interaction matrix. The team studied "progressive web apps," "hybrid web apps," and "pure web apps." Finally, the team analyzed the correlation of these trends in relation to processor metrics such as page faults, power consumption, browser and parent category usages, etc.

The the vFit GOLD is a wellness device intended to alleviate the symptoms of menopause. The student team worked to add an array of sensors for enhanced biofeedback to the user. The prototype shows the team's proof of concept in action, with pressure sensors to monitor the improved strength of the pelvic floor muscles, while also tracking and displaying data through an updated smartphone app.

This student team developed statistical models to give King County Metro the estimates of bus dwelling and idling time under different times of day, different types of weather, traffic and road conditions. The dwelling and idling time is related to the quantities of air pollutants such as Particulate Matter (PM), Nitrogen Oxide (NOx), and CO2. Optimizing bus dwelling time and minimizing idling time helps King County Metro reduce air pollutants in the greater Seattle area and improve environmental sustainability.

In aircraft door design, a challenge is that typical loads are quite low compared to sizing loads. Oldham joints are currently used in several doors because they simplify the interface between mechanism and structure. However, oldham joints can still have issues with high contact pressure, friction, and wear and tear. Significant weight and cost reductions may be possible with a design that could better accommodate those maximum loads and address the issues with current oldham joints using hyperelastic materials. The student team worked to identify a hyperelastic material able to meet Latécoère's door mechanism requirement and create a design and establish analysis to show compliance. Finally, they created a prototype for manufacture and testing.

The student team worked to build a customizable soccer arena and four tenth scale RC cars, starting from the NVIDIA self-driving JetRacer design, which utilizes artificial intelligence to play soccer competitively in the designed field. This work provides insights into the use of machine learning in a competitive environment.

Mining and the resulting materials play a critical role in everyday lives; but mining generates enormous volumes of water waste. All too often, this waste is stored or abandoned instead of treated, leaving open the opportunity to contaminate valuable water streams in the future. The student team worked to investigate how ceramic ion exchange resins can add value to mining wastewater treatment by extracting heavy metals.

Sample bags are commonly used in the food industry to grow bacteria in a food/media “broth” over a set period of time, until the bacteria reaches a detectable level. This sampling process is completely manual and usually requires more than one person. Larger bags especially pose a challenge to lab technicians. In 2020/21 a capstone team worked to improve the ergonomics and efficiency of sample bag handling within a typical lab work environment. This student team continued their work and developed a solution to improve the long-term efficiency and reduce the number of lab technicians required in the bag handling process.

Moonbeam uses virtual reality and artificial intelligence to transform the future of remote creative collaboration. They build tools to help corporate innovation groups work more effectively with startups without the constraints of geography. The student team worked to develop features leveraging conversational intelligence AI in order to support remote collaboration within VR to maximize productivity and creativity during strategic conversations.

Currently, NanoString has multiple consumable containers for bulk reagents ranging in size from 0.1L to 2L that have costs of goods (COGS) that are higher than desired and are not designed for sustainability. NanoString’s design currently consists of a transparent, rigid, sterile bottle with reusable cap assembly and product labeling. This student team worked to source new containers that reduce COGS and waste at NanoString’s consumers' sites.

Fluorescence microscopy is a powerful tool for the spatial profiling of tissue samples and provides biological details at the high resolution up to single cell level and beyond. One common drawback in the approach is tissue autofluorescence background, which often overwhelms the target fluorescence signal and causes poor data quality. This student team worked to build a prototype module to reduce the tissue autofluorescence during sample preparation step using LED light illumination. They also focused on temperature and moisture control to achieve high efficiency for Nanostring in-situ DNA hybridization. Sample tests were performed to prove the functionality.
