Radiex
During brain surgery, a retractor with metal blades holds brain tissue apart to maintain a working channel. Existing retractors hinder tumor removal and can cause further injury from pressure on brain tissue. Radiex’s cylindrical, compact design allows surgeons to access the brain through the smallest point of entry. Once in place, Radiex has the flexibility to gradually expand, increasing the surgeon’s area of visibility, without the added pressure to tissue.

Reactive Silver Inks
Silver-based inks are the heart of the printed electronics industry but they are difficult and expensive to manufacture. "Reactive silver inks are particle-free, can be patterned through fine nozzles, and are extremely simple to make resulting in high yields and increased performance for lower cost.

Rhino
Removing decaying, crumbling mortar from between bricks to subsequently replace it with new mortar is a messy, tedious and time-consuming job in the construction field. This process, joint-raking, generates so much silica dust that workers must wear respirators and goggles for safety. Rhino is a masonry tool attachment that can be used with any traditional rotary hammer. It improves the accuracy and safety of joint-raking, allowing masons to cover 50 percent more area during a given time.
