End-stage kidney disease patients visit dialysis clinics three times weekly cleaning their blood, requiring cannulation, i.e., insertion of needles into blood vessels. Successful cannulation includes consideration of needle angle, depth, and location. 4.4% of cannulation attempts fail, more often among less-experienced clinicians. We created a system to scan patient arteriovenous fistulas (AVFs) using ultrasound and processing scans using computer vision techniques to create a 3D-model that provides geometric information. To validate our system, we tested it on tissue-mimicking-materials modeling AVFs.

Vinyl weeding for T-shirt production is difficult for those without full function in both hands. For workers at CP Unlimited with cerebral palsy and limited mobility in one hand, this task is inaccessible. Funded by NYSID CREATE, the team developed a workstation enabling one-handed operation by heating vinyl to soften adhesive, clamping it to stabilize the workpiece, illuminating cut lines, and providing a waste collector to strip sticky vinyl from the picker. Our workstation makes weeding more efficient and accessible.

Off-the-shelf CubeSat attitude control systems are expensive. We designed and verified a low-cost three-axis attitude control system for the Cooper Union Satellite Launch Initiative. The system consists of three lighweight magnetorquers driven by a microcontroller and motor driver. These generate magnetic dipoles which interact with Earth's magnetic field to detumble and orient the CubeSat. By dramatically reducing the cost of attitude control, we aim to make space more accessible to university teams and organizations with limited funding.

We designed a compact accessory drive that safely assists our client, an active manual wheelchair user, to reduce his pain, exhaustion, and injury risk from manual propulsion over long distances. The system uses a disturbance detection controller to identify and amplify propulsion, braking, and steering impulses. Custom motors and batteries help our user tackle NYC's steepest hills while providing a minimum ten miles of range. After use our client can detach the drive within thirty seconds.

Multi-speaker array and spatial audio reproduction can be used to simulate realistic sound fields. We designed a modular speaker array system, capable of sound reproduction techniques such as ambisonics, wave-field synthesis, and cross talk cancelation, that utilizes a mesh grid system and ball-joint mechanism to orient point-source-behaving speakers within an anechoic chamber. This speaker array will help design better hearing aids, noise canceling headphones, and 3D audio for virtual reality.
