Smart Artificial Limbs
Traditional leg prosthetics enable amputees to maintain mobility and lead more active lives. Leg prosthetics most commonly fit amputees’ residual limbs via a socket that encloses the limb like a wooden clog. Because the socket exerts pressure on the limb’s soft tissue, pain and chafing, sores and blisters, and infection...

Deterministic Annealing Clustering
This software partitions a dataset into clusters of data using the Deterministic Annealing algorithm, a more sophisticated clustering technique than usually available in scientific and commercial software. The results provided are deterministic, i.e. unique (within the machine precision tolerance), whereas results...

System Enables Robots to Understand Contextual Commands
Today’s robots can accomplish many repetitive tasks, but their inability to understand the nuances of human language makes them mostly useless for more complicated requests. For example, if a specific tool is placed in a toolbox and a robot is asked to “pick it up,” it would be...
