The Coldfire SDN Diagnostics software is a flexible means of exercising, testing, and debugging custom computer hardware. The software is a set of routines that, collectively, serve as a common software interface through which one can gain access to various parts of the hardware under test and/or...

A computer program for use aboard a scientific- exploration spacecraft autonomously selects among goals specified in high-level requests and generates corresponding sequences of low-level commands, understandable by spacecraft systems. (As used here, "goals" signifies specific scientific...

G-Sample is designed for sample collection missions to identify the presence and quantity of sample material gathered by spacecraft equipped with end effectors. The software method uses a maximum-likelihood estimator to identify the collected sample's mass based on onboard force-sensor...

CTAEMS MDP Optimal Planner is a problem- solving software designed to command a single spacecraft/rover, or a team of spacecraft/ rovers, to perform the best action possible at all times according to an abstract model of the spacecraft/rover and its environment. It also may be useful in solving logistical...

A G-RAC attitude- control algorithm is used to minimize maneuver execution error in a spacecraft with a flexible appendage when said spacecraft must induce translational momentum by firing (in open loop) large thrusters along a desired direction for a given period of time. The...

The Grants Document- Generation System (GDGS) software allows the generation of official grants documents for distribution to the appropriate parties. The documents are created after the selection and entry of specific data elements and clauses. GDGS is written in Cold Fusion that resides on an SQL2000 database and...

Shape memory alloys (SMAs) are an enabling component in the development of compact, lightweight, durable, high-force actuation systems particularly for use where hydraulics or electrical motors are not practical. However, commercial shape memory alloys based on NiTi are...

Several modifications have been made to the design and operation of an extended-shaft cryogenic pump to increase the efficiency of pumping. In general, the efficiency of pumping a cryogenic fluid is limited by thermal losses (the thermal energy that the pump adds to the fluid). The sources of the...

A modification has been made in the mating halves of a cam-and- groove hose coupling to prevent rapid separation of the halves in the event that the cam levers are released while the fluid in the hose is pressurized. This modification can be duplicated on almost any commercially available cam-and-...

A method and bioreactor for the continuous production of synchronous (same age) population of mammalian cells have been invented. The invention involves the attachment and growth of cells on an adhesive-coated porous membrane immersed in a perfused liquid culture medium in a microgravity analog...

A report describes a rover-type robotic wheeled vehicle recently built for use as a testbed for development of software for future rover-type vehicles. This vehicle is a derivative of the Field Integrated Design and Operations (FIDO) rover, which is a prototype Mars- exploration rover that also serves as a terrestrial...

A document discusses a technique for enabling the reception of spacecraft commands at received signal levels as much as three orders of magnitude below those of current deep space systems. Tone-based commanding deals with the reception of commands that are sent in the form of precise...

This technology provides an efficient and cost-effective way to measure absolute position in one or two dimensions using a new Point Coupled Linear Transformer (PCLT). The PCLT detects movement and position on flat or curved surfaces. The nature of its design provides the sensor with...

Philips is offering an innovative technology to dispel humans (and animals) from an area where they are unwanted. The new and patented dispelling light source (DLS) concept is based on disturbance of humans and/or animals using photosensitive stimuli. When switching a DLS system to the specifically programmed flickering...

A company is seeking unique technologies for automated hand, chuck, and grip product assembly applications (not CNC machining). Multiple sizes of gripping device are acceptable for different sized parts. The chuck or hand technology should be general purpose in nature, and show...

Technologies are sought that will provide a natural method for extending shelf life, the prevention of food deterioration (oxidation and/or spoilage), and growth of pathogenic micro-organisms along the full chain of fresh or processed food. The solution could be effective at any stage, from feedstock to...

Computer programs that are used to define safety margins for fiery spacecraft re-entries and help detect planets outside our solar system are co-winners of NASA's 2007 Software of the Year Award. Software engineers at NASA's Ames Research Center developed the Data-Parallel Line Relaxation, or DPLR, which is used to...

Ohio State University physicists have invented a new kind of MRI technique to see inside a magnet that's smaller than the head of a pin. The magnet is a ferromagnet and has too strong of a magnetic field to be studied with typical MRI. The technique may eventually enable the development of extremely small computers, and give doctors...
