Branched scissor linkage and associated auxetic mechanisms

Branched variants of the scissor mechanism but with multiple arms Multiple arms, joined by a branched rivet allows 3D movement Benefit The scissor mechanism variant allows for nearly infinite shapes and structures. The structures can be collapsed into a compact shape then deployed into a large, functional shape. One embodiment is an extendable,...

Acoustic Liners with Innovative Core Geometries for Enhanced Low-Frequency Noise Mitigation

BACKGROUND Low-frequency (<~400 Hz) airborne noise has several detrimental effects ranging from exciting structural vibration modes (with potentially catastrophic results), reducing passenger comfort and payload integrity on commercial flights, restricting military mission capabilities, to contributing to noise pollution. Low-frequency noise is...

Coating, Layer, and Bulk Material for Extreme Thermal Protection

BACKGROUND High-temperature applications, such as rocket engine combustion output, can reach temperatures as high as 3,315 °C (6,000 °F). Enough heat to fuse a concrete surface, like a launch pad, into glass. Fused concrete has a limited lifetime as structural integrity is compromised in some cases immediately, resulting in potentially dangerous...

Zeolite-Coated Mesh for Oil-Water Separation

BACKGROUND Daily water demand and the increasing amount of industrial oily water discharge have become a worldwide problem. The presence of oil in water not only influences the surroundings but also damages the self-cleaning circulation of the ecological system at the time of recycling produced water. In the past few decades, polymeric membranes have...

ViLDAR (Visible Light Detection and Ranging): A Novel Speed Estimation System using Visible Light in Vehicles

OSU researchers have developed an advanced method named ViLDAR (Visible Light Detection and Ranging). In this method, the speed of a vehicle is detected using the vehicle’s LED headlight intensity information acquired by a photo-detector (PD) (Figure 1). The experimental results show that ViLDAR method outperforms the traditional RADAR/LiDAR methods...
