Magnetically Coupled Ball Drive for Actuation of Spherical Surfaces
Background and summary of the inventionRobust actuation of spherical surfaces is very challenging as the entire surface of the sphere needs to be accessible for omnidirectional motion. Traction forces applied to the exterior surface of the sphere are used for actuation. Application of large actuation torques is especially challenging as slip often occurs,...

VEHSHI - Vibration Energy Harvesting for Structural Health Instrumentation
Critical infrastructures are the mainstay of our nation’s security, health and economic well-being. Bridges interconnecting street networks are bottle necks of the built infrastructure. Disruption due to poorly maintained infrastructure, specifically progressing fatigue damage from initiation to conditions which are ultimately unsafe for operation,...

Granules Of Graphene Oxide By Spray Drying
Background:Graphene has recently received significant attention due to its many attractive properties, including: chemical and electrochemical stability; electrical conductivity; and theoretical surface area twice as Carbon nanotubes (CNT) and about 5 times of activated carbon. Producing CNT has remained quite expensive despite several decades of...

Popcorn-Like Growth Of Graphene-Carbon Nanotube Multi-Stack Hybrid 3D Architecture For Energy Storage Devices
Background:Energy storage devices, such as supercapacitors and lithium ion batteries comprise active materials, electrolytes and separators. For optimal energy storage, active materials should have large surface areas, chemical and mechanical stability, and good electrical properties, especially electrical conductivity. As such, carbon-based materials...

Direct Injection Of Plasma Activated Species (Pas) Into Liquid Solutions Assisted With Gas Buffering Housing
A method of stimulating chemical reactions within a liquid uses a gas plasma ejected from a gas-buffered plasma injection device to create a plasma-liquid interface. The injection device has an electrically-conductive housing with an inlet, an outlet and an electrode embedded in the housing interior so as to create flow paths through the electrode and...

Radio Scene Encryption And Authentication Process
A method is provided for encryption/decryption for secure the privacy of the information flow between two communicating nodes, and authentication to establish the identity of the communicating nodes in digital communications systems. A common secret or encryption key is generated at the two nodal ends of the communication link without prior dissemination....

Low Frequency Acoustic Vector Sensor
Background:Traditional underwater acoustic sensors such as hydrophones are pressure sensors responsive to oscillating pressure, a scalar quantity, in the field of the acoustic wave. A single hydrophone has no directionality. Vector sensors are responsive to water oscillatory velocity, a vector quantity, associated with the same acoustic wave. Thus,...

Wave Energy Harnessing Device
Background:As fossil fuels deplete day-by-day, need for alternate energy sources has been increased. Hydrokinetic energy is one such renewable source and over the years, numerous hydrokinetic devices have been proposed for extracting energy from waves (e.g., sea or lake surface waves) to produce electrical energy. The use of sea walls, track and rail...

Detection Of Hostile Intent From Movement Patterns
Background:Technology is often employed to detect whether suspects (individuals, vehicles, or mobile objects) are or may be a hostile threat to a target, such as one or more people, structures, vehicles, etc. Current technology used to detect a suspect typically requires that the suspect is within a proximity to the suspect's intended target. Examples...

Passive Underwater Acoustic System For Detection Localization And Classification Of Acoustic Sources
Background:One of the most challenging aspects of port security is providing protection from that approach from beneath the surface of water as well as from above the surface of water. Explosive device delivery can occur as explosive can be delivered underwater and can be carried to shore by people using underwater breathing apparatus such as SCUBA...
