NASA Langley Research Center has developed a novel fine interpolation technique that is useful in signal processing for applications in lidar, sonar, radar and similar modalities. The interpolation technique uses repeating waveforms, Fourier transform reordering, and Richardson-Lucy deconvolution to obtain faster and more accurate results.The prime target application is range finding, but the technique is equally suitable for differential absorption studies, such as determining CO2 concentrations in the atmosphere.
Provides an interpolation scheme much faster than those currently in use
Consists of a simple reordering of a Fourier transform array
Can be applied broadly with any repeating waveform, and not confined to PN code and PSK modulation
Compatible with lidar, radar, sonar and similar modalities
NASA inventors have developed a set of puncture self-healing materials comprised of commercially available, known self-healing polymer resin and additive blends. A range of puncture healing blends was developed by melt blending self-healing polymers with non-self-healing polymeric materials.
Puncture healing capability of the melt blends improves at higher temperatures
Thermoplastic materials that can repeatedly and intrinsically self-heal without the need for foreign inserts or fillers (such as microencapsulated monomer)
Blend of self-healing polymer materials with high strength polymer resins potentially enables the materials to be used in structural, load bearing applications
Fuel tank liners
Healing layers in ballistic protection for armor, helmets and other personal protective equipment
NASA Langley Research Center has developed a compact self-tuning damper to reduce vibration occurring at a fixed frequency. Tuned dampers reduce vibration of the base structure by the dissipation of energy. The magnitude of the dissipated energy is proportional to the range of motion. The NASA damper design allows the slider mass to achieve 2x-3x greater range of motion than that found in conventional devices. This enables 4x-9x more effectiveness for the same size and weight; or the same effectiveness for a 4x-9x decrease in weight. The damper is self-tunable and can be adjusted in effectiveness. The damper can be made small enough for use in wind tunnel tests or scaled up to large sizes, like those used in ...
There are products like battery operated bats available in the market to kill mosquitoes and insects but there is no battery-less innovation. My invention is very simple and very effective in killing mosquitoes as there is no need for recharging the battery of this mosquito bat. Only a bat and adhesive tape are required to build it. It will work to by trapping and killing mosquitoes. Salient features: (1) there is no need for recharging it. (2) the adhesive tape can be removed and replaced after use. (3) it is a very low cost design so anyone can afford it very easily. (4) it is safe and light weight (5) it can be used many ...
Gardeners bottom water through the lip in tight-fitting basin/pot configurations or in the basin in looser-fitting basin/pot configurations. The gap, wide or tight, and the watering lips permit entry of egg-laying female mosquitoes and exit of young, hungry mosquitoes.
The solution is a strip of fabric with a mesh tight enough to prevent crossing by mosquitoes but loose enough to permit bottom watering. This is akin to an adhesive bandage and can be purpose-built to ...
My wife is an ecclectic collector of recipes. I always joke with her that she has the
largest collection of Internet- supplied recipes in the world. And, despite that, she never
fails to ask me: “So, what should I make for supper tonight ?”.
A symptom of food preparation today, our laziness compels us to rely on quick food.
But, our taste buds and bodies yearn for a fresh, home-cooked meal. It easily explains all
these new services providing home delivered meal ingredients along with “easy-to-use”
preparation instructions. It also explains the newest kitchen appliances that are (almost)
all-in-one meal makers.
The truth is that ...
Our off-grid tiny home designs will be on a trailer powered by solar energy and propane. The goal is to use the latest in renewable technology to create a daily living space that is equal or better in providing comfort and the convenience of a larger home. The main difference between a Solarcycle tiny home design and other tiny homes is our focus on treating the home as a thermodynamic project involving long- term tiny home living issues such as waste management, ventilation, condensation, ergonomics, accessibility, energy efficiency, insulation, safety, and manufacturability. Right now, our prototype tiny home will include an incinerator toilet, solar power storage, propane heating and cooking, an energy recovery ventilator, LED lighting, and Aerogel insulation....
An NIH Tested, US Patented, FDA Approved Hi/Lo Density Polyethylene. flattened polymer ring to which a conventional latex or polyurethane condom is detach-ably-attached, that perfectly centers the condom over an erect penis only to be lowed over said penis so that the condom engages the top 1/3 of the shaft so that the condom is correctly positioned, which, as then engaged automatically transfers from the Applicator to the penis allowing the male to then continue to unroll it down the shaft before removing the Applicator. The design maintains, every time, the reservoir tip in perfect position to collect semen. Medically supervised clinical trials both at the NIH and The Gates Foundation indicate over 80% satisfaction with the efficiency and ...
A solar-silo is a silo-shaped structure having a clear geodesic domed roof surrounding a solar array positioned around the inside perimeter with a clear cylindrical column containing a light refracting medium in the center of the structure.
Each geodesic segment of the clear geodesic domed roof has an attached Fresnel lens with its focal point passing through the top of the light refracting column (with only the top of the refracting column illuminated by the magnified light of the Fresnel lens). The refraction column consists of a closed clear cylindrical container, with a ...
Instead of putting consumers in the counter-intuitive position of being in the "driver's seat" of a car without the need to maintain situational awareness and control over the vehicle, we use the culturally familiar concept of the "smartest horse in the barn" to create a physical separation between the consumer/travelers and the computer-controlled vehicle that is undertaking the journey, all the while providing reassuring backup control mechanisms--that ...
