Omni Jaw 5™ Powered Protrusion Cutter

With an interchangeable jaw, the tool can be used as a bolt cutter, punch, or shear.

In many manufacturing and construction activities, it is frequently necessary to remove a protrusion of material from a component or from a substrate surface. These removal operations include clipping the head off a bolt, or removing a nut, rivet, weld bead, or temporary assembly alignment tab from a substrate surface of assembled components. These operations may be required during normal assembly, during demolition of equipment or facilities, or during product repair or manufacturing rework activities.

Water-Saving Firefighting Nozzle

This nozzle extinguishes fires faster and with far less water than existing systems.

Fluorocarbon-based fire extinguishing agents are environmentally harmful since they cause depletion of the Earth's ozone layer. Fine Water Mist (FWM)-type systems have very favorable characteristics as replacements for existing Halon systems. Typically, these systems include nozzles for creating misting fluids using pressurized gas, and continue to show favor as a mechanism for fire prevention. In these systems, a liquid is typically directed into a central bore of the nozzle, which directs a flow of high-velocity gas. In some nozzles, the velocity and pressure of the gas are increased in a narrowed throat area of the bore, causing the atomization of the fluid into small droplets as the gas travels through the nozzle.

Sandia Cooler

Applications include laptops and other electronic devices, automotive, appliances, and any device comprising one or more forced-air exchangers.

Heat exchangers are used for the transfer of heat between two or more media. The media may be separated by a solid wall so that they never mix, or they may be in direct contact. Heat exchangers may be used in HVAC systems, power plants, and mechanical devices and systems that require heat transfer. Examples of systems where heat dissipation would be desirable are various electromechanical systems, and electronics applications such as conventional computing systems. In a typical computing system that includes a CPU, one or more memory devices, and other circuitry, cooling of the CPU in particular may be an important design consideration.

Ruck Dock Load Carriage Connector System

This device is used by civilians and military personnel who wear heavy backpacks, such as campers, rangers, firefighters, hikers, and soldiers.

Soldiers, civilians engaged in activities such as hiking, and public safety personnel engaged in search and rescue missions all require reliable systems for the effective carriage of necessary equipment. The most simplistic backpacks and rucksacks often do not incorporate a frame or other rigid load-distribution structure. Such frameless packs are suitable only for relatively light loads, as the bulk of the weight is transferred solely at two points: the shoulders of the user. Additionally, without auxiliary mounting points, the frameless backpack is subject to significant bouncing or swaying as the user runs or jumps.

Reducing Inaccuracies in Force/Haptic Feedback Systems

This novel algorithm automatically compensates for the errors introduced by physical factors, enabling the control system to adjust the applied force accurately.

Researchers at NASA's Armstrong Flight Research Center have developed a new technology to reduce inaccuracies in force/haptic feedback devices and systems. Used at NASA in aircraft simulations for force feedback pilot controls, these systems involve a servomotor applying precise force to a specific point based on very accurate measurements. However, because the force instrumentation often cannot be placed directly at the point of interest, a mechanical assembly is used, linking the force transducer to the target point. Unfortunately, this mechanical assembly introduces inaccuracies due to its own forces of gravity, friction, and inertia.

Low-Pressure Plasma Cleaning of Aerospace Components Using Breathing/Compressed Air

A method for precision cleaning of aerospace components is needed that does not use hazardous or environmentally harmful commodities. Historically, precision cleaning methods have utilized solvents that have contributed to the depletion of the ozone layer or had high potential for contributing to global warming. Solvent cleaning produces large waste streams, and some solvents may be phased out in the future due to the environmental concerns.

Chain Drive Dust Conveyer

This method clears cutting fines from a sampling tool without the use of fluids.

The Mars 2020 coring drill will generate a significant amount of dust and debris (known as fines) due to the volume of milled material displaced by the corer's annulus. These cuttings must be removed to ensure that the drill does not jam. The typical method involves fluids, which may not work on Mars due to the atmospheric conditions.

BiBlade Sampling Chain

This tool enables multiple sampling attempts per sample.

The BiBlade sampler has been developed for potentially acquiring samples from the surface of a planetary body. The tool could conceivably be used in both in situ and notional sample return missions to planetary bodies including asteroids, comets, and moons. While the tool was designed for planetary sampling missions, it could have terrestrial applications as well.

Micro Acoustic Resonant Chambers for Heating/Agitating/Mixing (MARCHAM)

This device can be used for extracting amino acids in microfluidic or benchtop designs, and could be scaled up to accommodate large samples for mixing and extraction.

To measure organics in a fluid sample, one either has to bring the sample in the form of a colloid to the instrument, or extract the organics from the sample and bring the liquid extract to the instrument. The disclosed technique enables both extraction and transport of the fines or the organics.

Advanced Tool Drive System (ATDS) Camera Positioning Mechanism (CPM)

Robotic servicing of a satellite in low earth orbit (LEO) or geosynchronous Earth orbit (GEO) requires advanced systems capable of meeting the harsh environments of space. To support this effort, the Goddard Space Flight Center Satellite Servicing Capabilities Office (SSCO) has developed a camera positioning mechanism that will be capable of viewing features on a client satellite. Application of the CPM technology would be in multiple areas of spaceflight requiring robotic servicing including space exploration, planetary science, Earth science, and manned spaceflight.
