iCrutch: Addressing the Therapeutic Challenges of Nystagmus

Acquired nystagmus is a condition characterized by repetitive, involuntary eye movements that impair visual stability and quality of life. Current treatments, including pharmacological therapy and surgery, are often ineffective, non-specific, and unable to adapt to progressive symptom changes. Here, we present a real-time eye-tracking system that detects nystagmus, classifies its subtype using machine learning, and computes a corrective motion vector. The system integrates infrared cameras with Fourier-based processing to distinguish pathological oscillations from voluntary gaze shifts, achieving 99% detection accuracy with a 10 ms response latency. A computational model predicts the necessary counteracting motion to stabilize gaze, mapping corrective movements to extraocular muscles. Preliminary results demonstrate high precision in nystagmus classification and motion compensation, establishing a foundation for future electrode-based stimulation therapies. This system represents a step toward adaptive, closed-loop therapies.

Recycling Neolast: A Sustainable Spandex Alternative

In collaboration with Celanese, Under Armour has developed a high-performing elastic alternative to spandex: Neolast. With a green, solvent-free manufacturing process, Neolast shows promise in addressing the textile industry’s challenge of achieving the stretch of spandex without the environmental harm. While the fiber manufacturing is already more sustainable, Under Armour has a high level of interest in recycling the fibers after they’ve been woven into composite textiles. Recycling stretchy fabrics like spandex is tough – they gum up machinery, tend to lose their properties post-processing, and recycling processes are typically low yield and expensive. Circumventing these challenges would allow them to make Neolast more green, reusing textile waste and preventing textile accumulation in landfills.
