The Romanian concept of active suspension with pneumatic actuators is in patent application OSIM-A/00368/28.05.2015 and was in PCT/EP2016/061515_23.05.2016 and is able to large static and dynamic car trim adjusting, assuring thus:
• ground clearance increasing on bad road to protect the passengers and the car;
• decreasing the ground clearance on speed road, to increase stability and cruise speed;
• increasing longitudinal and transverse stability by adherence increasing due to improved contact wheel ground
• increasing body stability and so the comfort but the same reducing turbulence round the car decreasing drag resistance and thus fuel consumption and pollution
• optimal positioning towards longitudinal and transverse axis, to reduce the turbulence round the car, especially under body, to decrease ...

Experts have estimated that 8.3 billion metric tons of plastics have been made and approximately 5 billion metric tons have already been discarded, with an abysmal recycling rate of only 600 million metric tons. This is despite the fact that recycling alone can save 40 to 90 percent of the inherent energy in plastics relative to the production of virgin plastics—energy savings, which if harnessed, could result in massive-scale economic and environmental advantages. Up to 40 percent of all plastics are used for minutes to hours to days in single-use packaging applications (items commonly composed of plastics like polyethylene, polypropylene, polystyrene, or polyethylene terephthalate, also known as PET), while the estimated time for many plastics to degrade in a ...

Someone in the US has a stroke every 40 seconds (nearly 800,000 strokes per year) and stroke is a leading cause of long-term disability. When brain damage occurs after a stroke, it can disrupt the nerve messaging between the brain and muscles, causing paralysis. People who suffer a stroke often experience arm and hand paralysis, which can lead to a loss of independence if they cannot adequately care for themselves, and result in the need for long-term care either at home or in a nursing home.

The approaches to coping with and restoring lost hand function can include using physical rehabilitation, braces, assistive devices, and hand exercise devices. A supportive brace helps with weakness and preventing painful muscle cramps, ...

When batteries catastrophically fail, they can overheat, rupture, and or explode. Susceptible lithium ion batteries are everywhere - in consumer products like e-cigarettes, mobile phones, and electric cars, as well as in airplanes and facilities for alternative energy storage. Failures bring serious consequences:

-From 2015-2017, e-cigarette injuries sent more than 2,000 people to the hospital across the U.S. Several incidents were disfiguring or fatal. https://tobaccocontrol.bmj.com/content/28/4/472

-In 2016, Samsung recalled more than one million Galaxy Note 7 phones after at least 35 reports of overheating or exploding batteries worldwide.

-In May 2019, Tesla issued a software update to adjust battery settings in Model S and Model X cars after videos of cars bursting into flames in Asia became public.

Eight million metric tons of plastic waste, including polyethylene terephthalate (PET) bottles, enter the oceans each year, creating huge man-made islands of garbage. Experts estimate that by 2050, there will be as much waste plastic in the ocean by mass as there are fish. It’s a global environmental problem that poses a serious risk to wildlife, particularly in marine environments.

Now imagine something as simple as a microbe that can degrade those plastic bottles. Such an organism exists. Ideonella sakaiensis 201-F6 is a recently discovered bacterium that can degrade PET using its PETase enzyme, but PETase doesn’t yet work fast enough to solve plastic recycling at the industrial scale.

However, while working to solve the crystal structure of PETase, an international ...

PROBLEM/MOTIVE: In Cycling, the Cyclist faces two obstacles:
-there is dead-center at top of pedal-stroke, where Cyclist must apply huge force resulting in negligible torque and
-there is not even slight helping overlapping of pedaling power-periods (when Cyclist produces work), resulting that each single leg has to be so strong to move the bicycle alone.

In this Mechanism the two crank-arms are non-rigidly connected together via variable-transmission-ratio gears, with predefined variable phase-difference, in order to impressively resolve both problems.

Installing it on Bicycle, minimum phase-difference is decreased to much less than 180-degrees of classic Bicycle, resulting in avoiding dead-points of pedal-stroke, while -and this is the most important- LARGE OVERLAPPING of actually power-periods is achieved.

In this current world where technology is growing up day by day which is gradually increasing the usage of precious and expensive things in day to day life for making works handier, the need for security is also hyped in all areas. On the other hand as a human being, we always want to get maximum possible results with less effort and expense. We know well that in the 21st century biometrics is a very effective way of security authentication, but again using the physical biometrics sensors for this purpose makes it a lot more expensive as well as a bit complicated for a common man to afford and use.

When thought variedly for the solution to this problem ...

Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band signals have large EM wavelengths that can penetrate the plasma sheath layer with minimal loss, which is one of the well-known solutions in the community. However, conventional antennas rely on EM wave resonance, and therefore typically have a size of more than one-tenth of the EM wavelength, which is 10 to 100 km long at VLF band. Therefore, even an electrically small VLF antenna would have huge dimensions and enormous power consumption, which is impractical to ...

The air conditioning of spaces has become a need of the human being to have a better quality of life, it is common for many families to have equipment to cool the air in their homes in the spring and summer seasons; In hospitals it is important to have air cooling systems for the hygiene conditions that are required, as well as to maintain comfort in public places such as cinemas and restaurants. Particularly in the geographical areas where there is a warm climate, air conditioning equipment is very necessary to counteract the high temperatures. Our team has identified certain problems that still exist regarding conventional air conditioning equipment:

1.- There is a part of the population that cannot ...

Vascular Perfusion Solutions (VPS) has developed a new, unique, and innovative medical device that extends organ and limb viability — the Universal Limb/Organ Stasis System for Extended Storage, or ULiSSES™. VPS is working with a team of world-class scientists to advance ULiSSES™ through FDA clearance and into the clinic. ULiSSES™ will provide organ and limb resuscitation, preservation and transport capabilities both civilian and military environments.

The ULiSSES™ device operates using a combination of fluidics, and mechano-elastic principles for the hypothermic, oxygenated, perfusion, preservation, of limbs and vascularized tissue. The device does not rely on electrical power to operate. Instead, it harvests energy from expanding compressed oxygen to simultaneously drive pulsatile perfusion of vascularized tissue and oxygenation of the preservation ...
