Design, build, and validate a compact dark-field optical inspection module capable of detecting particles and contamination on opaque objective surfaces. The project will develop a common illumination and detection architecture using off-the-shelf optical and mechanical components while minimizing bright-field reflections through dark-field illumination techniques. Students will design the optical layout, mechanical packaging, image acquisition system, and image-processing algorithms required to detect approximately 100 µm particles with high reliability. The final system should satisfy packaging constraints, achieve processing times below one second per image, and demonstrate robust contamination detection performance using representative test samples.

The TRACE project (Target Recognition via Adaptive Contrast Enhancement) challenges the student team to develop a prototype system that improves the visibility of a man‑sized target through adaptive contrast‑enhancement algorithms, man-sized assumed to be 1.5 meters square at 250 meters or about 2.7 mrad angular resolution. Using standard commercial off‑the‑shelf (COTS) hardware, the team will collect test imagery across varying illumination conditions (full sun, overcast, dusk/twilight) and diverse target–background combinations such as white clothing, camouflage, urban environments, and desert terrain. Core project objectives include defining a quantitative visibility metric, performing research into contrast‑enhancement techniques, and developing a post‑processing algorithm that measurably improves target visibility. The final system should operate in real time at 30 Hz with 100 ms processing latency.

As a stretch goal, the team can integrate live target marking with real‑time enhancements onto the scene in a wide-field-of-view lens.

Visibility metric:
This is intended to be a scalar score that is computed by the software based on the contrast of the target to its background. It can be per pixel or given to the target as a whole. Then after the post-processing enhancement algorithms, there should be able to an increase in the metric. This will require research, thought, and perhaps some experimentation by the team to land on a suitable method for calculating "visibility".

Hardware:
COTS monochromatic visible spectrum digital camera and lenses. Team can run video processing discrete embedded electronics, but running all software on a computer with accompanying display is acceptable.

Testing:
At least 3 light levels, e. g. full sun, overcast, dusk, twilight, etc.
At least 2 target contrast levels including light or reflective colored clothing and camouflage
At least 2 different environments, e. g. urban, sandy, rocky, forest, etc.
Stretch goal to capture and enhance images of Bigfoot.

Project Goal/Summary: Advance last year’s CAMDAR prototype into an integrated, working system that uses two video cameras to identify and localize an at-risk individual in three-dimensional space, directs an existing alt-azimuth radar mount toward that person, measures non-contact vital signs with updated millimeter-wave radar, and displays the person, posture, location, vital signs and alert status for a responder.

Project Background: Last year’s team established the core CAMDAR architecture, built the camera/computer-vision pipeline and a functional aimable altitude–azimuth radar platform. The major unfinished tasks were reliable two-camera stereovision/3D localization, robust radar vital-sign acquisition, and complete subsystem integration. Their final report specifically recommends improved stereovision calibration/depth estimation, radar processing, mount stability/pointing accuracy, and earlier incremental integration. This year is an ADVANCE + INTEGRATE project—not a restart.

Requirements:
• Step 1 – Inherit + baseline. Begin with last year’s hardware, code, camera subsystem, Jetson/main console and alt-azimuth mount. Reproduce known functions and define quantitative baseline tests before modifying the system.
• Step 2 – Build true 3D vision. Integrate two synchronized/calibrated cameras with overlapping fields of view. Detect/track multiple people, assess posture (lean/slump/fall/collapse), and generate stable real-time X-Y-Z coordinates for the selected person of interest.
• Step 3 – Coordinate transform + aiming. Convert camera-derived 3D coordinates into radar azimuth/elevation commands. Reuse the existing turret design; refine rigidity, calibration, repeatability and pointing accuracy rather than redesigning from scratch.
• Step 4 – Upgrade mmWave radar. Integrate the identified newer millimeter-wave radar board(s) and establish reliable non-contact respiratory-rate and heart-rate measurement. Temperature may be added if supported by a separate validated sensor; do not make it a core radar requirement.
• Step 5 – Close the autonomous loop. VISION → PERSON-OF-INTEREST → 3D LOCATION → AIM → RADAR ACQUISITION → VITAL-SIGN ANALYSIS. Demonstrate repeatable handoff from vision to radar without manual aiming.
• Step 6 – Build the CAMDAR display. Create a clear real-time GUI/heads-up display showing the monitored scene, highlighted person of interest, posture/risk state, 3D position, radar targeting status, respiratory rate, heart rate, confidence/quality indicators and system state.
• Step 7 – Alert + validate. Generate a responder alert when predefined visual + physiologic criteria are met. Validate with staged non-clinical scenarios involving multiple people; quantify localization error, aiming error, vital-sign accuracy versus reference devices, detection/alert latency, false alerts and end-to-end reliability.

Project Goal/Summary: Design and build CELLBOMB, a benchtop laboratory instrument exposing blood or blood constituents to independently controlled rotational/propulsive shear and positive or negative pressure (vacuum) representative of continuous-flow mechanical circulatory support (MCS). The platform will enable controlled study of red-cell hemolysis and platelet activation and provide a basis for standardized blood-pump testing.

Project Background: Temporary and permanently implantable MCS devices commonly use high-speed rotary impellers. Blood passing through these pumps experiences substantial shear together with regions of positive pressure and negative pressure/vacuum. Shear-induced blood damage is well studied; the independent and combined effects of pressure/vacuum + shear are less well characterized. CELLBOMB will provide a reproducible platform for separating and systematically varying these stresses.
Requirements:
• Step 1 – Define the MCS operating space. Establish representative ranges of impeller speed, fluid shear, positive pressure, negative pressure/vacuum and exposure time. Define target test conditions before fabrication.
• Step 2 – Engineer the CELLBOMB pressure vessel. Design a transparent cylindrical chamber with removable sealed end caps, gaskets, sampling/access ports and axial bearings. Perform pressure/vacuum and structural safety analysis before testing; use containment and approved laboratory safety procedures.
• Step 3 – Build three CELLBOMB platforms. A) Demonstration Bomb: ~2–3 in diameter × ~12 in, visualization/engineering demonstration only – NO BIOLOGIC FLUIDS. B) Experimental Bomb: ~25 mL with a custom 3D-printed impeller. C) MCS Bomb: ~10–12 mL incorporating an actual Abiomed/J&J blood-pump impeller.
• Step 4 – Build the magnetic impeller drive. Develop an external electromagnetic/inductive drive acting on embedded impeller magnets, avoiding a rotating shaft penetration. Measure/control RPM while preserving chamber sealing.
• Step 5 – Characterize shear + pressure/vacuum. Measure pressure/vacuum, impeller speed and, where feasible, flow and temperature. Use analytical methods and/or CFD to define flow patterns, shear-stress distribution and exposure.
• Step 6 – Integrate controller + GUI. Develop one controller/interface for all three chambers. Set/display RPM, pressure/vacuum and exposure time; log sensor outputs and experimental conditions; include safety limits, alarms and emergency shutdown.
• Step 7 – Validate + perform biologic testing. Validate first with water/saline or appropriate non-biologic fluids. If time, approvals and resources permit, test blood/blood constituents across defined shear × pressure × time conditions. Primary biologic endpoints: hemolysis/red-cell damage and platelet activation.

1. Project description: The United States Coast Guard (USCG) faces a persistent and growing capability gap in detecting semi-submersible and low-profile vessels (LPVs) used by transnational criminal organizations for narcotics trafficking. These vessels are deliberately engineered to minimize radar and visual signatures, rendering conventional maritime surveillance methods largely ineffective. Distributed underwater acoustic sensor networks — commonly known as hydrophone arrays — offer a compelling solution by exploiting the unavoidable acoustic signatures generated by vessel propulsion systems. This capstone project challenges students to design, build, and demonstrate a scaled proof-of-concept (PoC) hydrophone array system that integrates distributed sensing, real-time signal processing, machine learning-based classification, and a command-and-control (C2) dashboard interface.

At full operational scale, such a system would consist of networks of seafloor-mounted hydrophone nodes spanning hundreds of nautical miles, feeding acoustic data into AI-powered fusion centers that cue intercept assets in near-real time. For this capstone effort, students will demonstrate the same fundamental technical concepts at small scale — using a network of 2 to 5 prototype sensor nodes deployed in pool and/or open-water lake environments — targeting small, motorized watercraft as acoustic sources in place of full-sized vessels. The core technical challenge is identical to the operational problem: detect, classify, and localize an acoustic source of interest using a distributed sensor network, with results presented to an operator through an intuitive command interface.

PROJECT INTENT. Build an undergraduate-engineering prototype that receives actual spent hemodialysate collected from dialysis treatments, selectively removes undesirable solutes, measures the residual chemistry, adds back missing constituents, mixes, re-measures, and either RELEASES or REJECTS the regenerated dialysate. Fresh commercial dialysate will serve as the reference control. The project is a bench engineering system only and is not intended for human use.

Project Background: This project builds directly on two years of UA work. Chemical Engineering students first defined the chemistry of fresh versus spent dialysate; last year's Biomedical Engineering team then used actual spent dialysate to build a working WATER ECONOMY system that removed urea/ions, filtered and disinfected the fluid, and recovered purified water. This year the goal is to regenerate the dialysate itself rather than strip it completely to water: preserve useful constituents where practical, remove harmful/excess components, determine what is missing, and reconstitute the fluid toward a defined fresh-dialysate composition.

Project Goal/Summary: Develop a closed-loop system that recaptures actual spent hemodialysate, selectively removes accumulated wastes/excess solutes, measures the remaining useful constituents, adds back what is missing, and verifies regenerated dialysate against fresh dialysate for reuse. SELECTIVELY CLEAN → MEASURE → RECONSTITUTE → VERIFY → REUSE. Long-term goal: reduce water/dialysate waste and enable smaller home and ultimately portable hemodialysis systems.

This invention relates to a novel, real-time blood loss quantification device for use in surgical and obstetric settings. The system estimates blood volume absorbed by surgical gauze or sponges by extracting hemoglobin into a fixed-volume reagent (e.g., Drabkin’s reagent), forming cyanmethemoglobin, and then quantifying absorbance at 540 nm using an optical detection module based on Beer–Lambert Law.

The device includes a disposable gauze cartridge with a sieve, a reagent chamber, and an optical cuvette aligned with dual-wavelength LEDs (540 nm and 850–880 nm) and a photodetector (e.g., OPT101). A microcontroller calculates hemoglobin concentration, compensates for turbidity via secondary IR LED measurement, and estimates total blood loss in mL using patient-entered baseline hemoglobin.

The solution improves accuracy over gravimetric and camera-based methods (e.g., Gauss Triton), minimizes interference from non-blood fluids, and is suitable for clinical, low-resource, and emergency settings.

Pelvic organ prolapse affects millions of women, yet the primary non-surgical treatment option, the vaginal pessary, remains a passive device that offers no information about vaginal health or device performance. This Phase I project will develop the Smart Pessary, a soft intravaginal device made of medical-grade silicone that contains miniaturized pH and temperature sensors, a low-power microcontroller, and wireless data transmission. The goal is to demonstrate the technical feasibility of continuous monitoring of the vaginal environment to detect early signs of infection or device-related complications. The objectives include fabricating a functional prototype, validating sensor accuracy and stability in simulated vaginal conditions, confirming data transmission and onboard signal processing, and assessing the device’s performance during extended laboratory use. This work will establish feasibility for a future pathway toward real-world deployment.

Pointe shoes are an essential tool in a ballet dancer’s training and career. These shoes must support dancers as they balance, turn, and jump on the tips of their toes during class, rehearsal, and performance. They must protect the dancer’s foot and ankle alignment, while visually appearing as an extension of the dancer’s line.

Footwear design has changed radically in the past 20 years, yet the technology behind the pointe shoe is centuries old. Most point shoes are handcrafted from traditional materials including paper, glue, leather, canvas, and satin. Shoes made in this way do not provide acceptable fit to every foot, do not adequately transfer energy about the foot, are break down quickly when subjected to repeated loading cycles and as a result they contribute to injury.

The goal of this project is to redesign the pointe shoe from the ground up. To build a shoe that is customized to the foot shape and the needs of the dancer, that transfers energy in an efficient manner, that is can last through many cycles of loading, all the while maintaining the aesthetics of the classic handmade point shoe.

As human spaceflight expands toward longer duration missions on the Moon and eventually Mars, the need for reliable in-situ suit maintenance becomes increasingly important. EVA suits are complex and costly systems, relying on multiple spare suits is not a practical solution for sustained exploration. Instead, extending the usable life of each suit through effective repair and maintenance strategies offers a more efficient and reliable approach. Developing methods that allow astronauts to address damage and wear as it occurs will help reduce mission risk while also lowering overall system cost.
By focusing on practical repair techniques and preventative maintenance, the work supports a shift toward suits that are not only high-performing but also maintainable by the crew using limited resources. The ability to restore structural integrity during EVA and address material degradation between EVAs contributes to mission resilience, especially in harsh lunar conditions where abrasion and wear are persistent challenges.
The team will be ask to develop project concepts, but one initial concept (included in the proposal funded by NASA) is the development of a structured post-EVA suit inspection and repair decision system intended to streamline and take guesswork out of evaluation of suit condition following mission use. The focus would be on creating a practical visual inspection framework—such as a checklist or decision tree—that guides users through identifying damage types, assessing severity, and determining whether a suit is repairable or requires replacement. The intent is to reduce reliance on expert judgment and improve repeatability and clarity in post-mission decision-making, particularly for users with limited suit maintenance experience.
This system could be tested during realistic post-EVA scenarios conducted at the Biosphere 2 Space Analog for Moon and Mars Laboratory (SAM) where crew members evaluate suits after field use. Because SAM operates as a hermetically sealed and mission-simulated habitat, it provides a realistic setting to assess how well users can apply the decision framework under conditions such as fatigue, time pressure, and environmental contamination. Performance would be evaluated in terms of decision accuracy, time required for assessment, and overall usability of the inspection process.
Following that, or a different direction altogether, could focus on the development of a repair kit and associated procedures for EVA suit refurbishment following use. This kit would be designed for IVA application using pressurized gloves and would include a limited, standardized set of validated repair methods such as adhesive patching, mechanical reinforcement, and protective surface coverings. The emphasis is not on providing every possible repair solution, but rather on enabling reliable, repeatable repairs for the most common types of outer-layer damage including abrasion, punctures, and seam degradation. Along with the outer layer you should develop a refurbishment process for IVA suit bladders aimed at extending operational life and maintaining pressure integrity after repeated use. This approach would focus on controlled-environment repair techniques such as localized patching, heat or adhesive sealing, and the application of rubberized coatings or restoration materials. Unlike EVA outer-layer repairs, this concept assumes a more controlled intra-vehicular setting where precision and repeatability can be prioritized over field-speed execution.
Testing these concepts within the SAM facility would allow evaluation of how the kit performs under realistic operational constraints. This includes working with reduced dexterity due to gloves, managing potential contamination from simulated environmental conditions, and completing repairs under time-limited, mission-like scenarios. Additional focus would be placed on consistency of repair outcomes across different users, as well as the overall practicality and efficiency of performing repairs within a confined habitat environment.
