A paper presents further results of continuing research reported in several previous NASA Tech Briefs articles, the two most recent being “Stochastic Representations of Chaos Using Terminal Attractors” (NPO-41519), [Vol. 30, No. 5 (May 2006), page 57] and “Physical Principle for...

A one-step laser etching process proves advantageous for the microfabrication of optics, electromechanical systems, and fluidics. Utilizing a laser-absorbing fluid against the back side of virtually any solid, transparent material, any of a number of lasers can perform micro-etching of 1 millimicron to 10 millimicrons....

This micro-reinforcement technology enables new applications where existing thermoplastics, elastomers, thermosets, and reinforcing technologies have not had sufficient toughness or fracture strength, particularly at elevated temperatures. The new reinforcement technology does not...

A company seeks technologies or “safeners” that minimize the negative impact of pesticides on crops, such as physiological or cosmetic damage. The safener must have utility on a broad combination of crops, result in no inhibition effect or other performance consequences on the active...

A valve technology is sought that can be used with a propellant- gas-based device aimed at the consumer goods industry. The valve will be used with a canister of propellant gas, in a handheld consumer device, and needs to be small, lightweight, and low-cost. The size should be in the millimeter to...

The SCM5B, SCM7B, and SensorLex® 8B signal conditioning modules from Dataforth (Tucson, AZ) are all fully encapsulated, making them corrosion-resistant and well suited for use in rugged environments like wind turbines.

Tamper-evidence properties are often achieved by adding secondary packaging such as foil seals or heat-shrink seals that inflate the cost of the container. This invention provides a proven technology to produce an injection-molded, tamperevident plastic lid for a container that can be used in the...

Most atomic clocks are bench-bound, and even portable units can weigh in excess of 10 pounds. This invention is a cesium laser atomic clock that can be constructed using photoresist MEMS (microelectromechanical system) technology. The glass cell measures about 1 cubic...

A company seeks a technology to enable sprayable fungicides and a new additive that is compatible with current insecticides and fungicides. The technology must treat both sides of the leaves uniformly. Moreover, since spraying equipment represents a major time and cost investment from...

A broad-spectrum pathogen disinfectant is sought that can kill Clostridium difficile (spore phase) in less than five minutes of contact time; preferably within a minute or less. A formulation that requires longer than a minute is also of interest if it can be formulated to provide ongoing protection....
