A novel computer vision-based approach for fatigue crack detection using a video stream was developed. The technology offers significant advantages over traditional inspection and fixed sensor-based methods and overcomes many of the limitations and concerns with static image and image processing based techniques.
This method utilizes a novel solid catalyst made specifically for olefin epoxidation. The catalyst utilizes a base in order to allow hydrogen peroxide to be utilized as an oxidant. Further the system allows for a constant flow of feedstock to flow through the catalyst with minimal leaching of the metal from the catalyst allowing for a longer life of the catalyst.
This invention relates to a class of devices, the Radar Energy Absorbing Low Draw Vortex Generator (RAD-LDVG), which produce vortices over external or internal aerodynamic and/or hydrodynamic surfaces.
This invention provides an improved method for producing a novel interfacing capillary device that is less costly and more durable than existing sheathless devices. This simplified production method does not require sample dilution, etching, or precision hand tools, and is automated and reproducible.
This invention is a tubular electrospun scaffold of natural protein gelatin and synthetic polyglycolic acid (PGA) / poly-lactic-co-glycolic (PLGA) polymers in a bioreactor system connected to a flow circuit and seeded with cultured fibroblasts and endothelial cells.
The invention is a lightweight device that remains tethered in place to a base unit on the ground by cables, can be equipped with various types of surveillance equipment, and can quickly elevate vertically into the air by simple controls.
The present invention employs a novel use of multiplexing and cross-connect architecture to improve energy efficiency in optical networks.
This invention uses a photoactive element between graphene electrodes to create a photovoltaic device that not only produces electricity from sunlight, but also transmits its infrared energy for use in an attached thermal energy device.
The invention is a composite system useful for indicating and preventing fatigue on essentially any metallic structure.
