All Dimensional Continuous Fabrication
SUMMARY Three-dimensional printers currently in the market generally operate in a top-down additive process in which a printer head, constrained to move in a flat plane (by a two-dimensional stage), dispenses a plastic material onto a build surface. To enable three-dimensional formation of the plastic material, the building surface traverses in a d...

Tube Launched UAV
SUMMARYLehigh University has designed a few concepts for UAV aircraft, presumably unmanned ditto, launched from a tube such as a grenade launcher, gun, mortar, etc. The aircraft is packed such that it fits inside the tube and then deploys its wings after exiting from the tube. The first concept is a UAV with a “flying wing” configuratio...

Fish Scales Reducing Boat Accelerations
SUMMARY Lehigh University has developed plates, similar to fish scales, that are mounted on the bottom of a boat. The plates are designed to deform and/or deflect under water pressure in such a way that the maximum vertical acceleration of the boat is reduced. The invention is applicable to small high-speed boats, as they suffer heavily from vert...

Boat Suspension
SUMMARY Lehigh University has developed a boat suspension system that absorbs, deflects and otherwise mitigates undesirable hull motions while increasing rider comfort, vessel stability and maneuvering performance at high speeds. There are on the order of 18 million pleasure boats in the US, a substantial fraction of which are powerboats. Most of ...
