This adaptive thermal engine achieve variation of the displacement and/or the compression ratio to assure optimum combustion conditions and provide power to the load adaptation engine, with direct implications on growth power and reduced consumption.

Advantages of new technology refer to a continuously / infinitely Variable Compression Ratio & Variable Displacement mechanism that offers a compression-ratio range from less than 7:1 to more than 20:1 and/or variable displacement in range 0-100%; ensure optimum combustion conditions and adapting to charge power engine, with direct implications on growth power and reduce consumption and the possibility of using different fuels. For variation of compression ratio the decrease of the consumption is 30 – 40 % and for variation of displacement is estimated ...

This is an idea that has been in the back of my mind for some time now, and this seems like the perfect opportunity to bring it to life. This is a device that will darken a small portion of a vehicle windscreen in order to block the sun from the drivers eyes. This works by installing a thin film of photochromic material on the inside of the windscreen, and an emitter in (or on) the dash of the vehicle. The emitter works by shining a low power ultra violet light onto two, independent axis controlled mirrors that redirect the UV light onto a specific position on the windshield. The photocromic material darkens with the presence of UV light, ...

The metal additive manufacturing industry is advancing rapidly as a manufacturing process. It is over a $1B market and forecast to be nearly $10B within 8 years. There are massive benefits such as avoiding tooling costs, quicker turn around, and permitting designs of more complicated shapes. The market would likely be even greater except there are several major issues. Some of the biggest pain points are as follows:

1) Costly equipment and raw materials makes additive unaffordable for much of mass manufacturing.
2) The printing processes (micro-welding or sintering) can adversely impact material properties such as strength, fatigue, and corrosion resistance.
3) Porosity and voids can be difficult to predict or control and can cause failures.
4) There is ...

Contrary to logic and general theory, a bullet with a flat tip moves in water several times faster than a bullet with a sharp tip. This effect is simply explained: a flat tip creates cavitation bubbles that rub on the rest of the bullet surface very slightly. That is, the total area of friction is reduced so much that it fully compensates for the enormous resistance of the flat tip.

Is it possible to achieve this effect in aerodynamics? Everyone says no, since cavitation is only a property of the fluid. But even in the '30s, it was proven that at high speeds the gas has fluid dynamics. Just this discovery allowed to improve cooling technology.
But what configuration ...

A Smart Hydroponic food module that monitors, grows and takes care of your plants. Our Vision is to foster behavior change among urban households towards farm produce and drive hyper-local urban production. We make farming so much simple and easy that now anybody can grow their own food. Gone are the days when you need hard labor and farming experience to get your harvest.

The journey began with a quest to bring in self-sustenance and pesticide-free healthy food to our home, foster behavior change among urban households towards farm produce and drive hyper-local urban production.

Further our current agricultural system is very inefficient, food produced in one corner of the country being sent to other corners, poor supply chain, ...

People spend lots of time when going shopping. This is because manufactured clothing are made in limited sizes and customers get the cloth they fit if they are lucky and if they like the clothing and many other factors.

This is a mechanism is for end users to get notified when there is a nearest clothing they will like and fits. This is done by using an AI tech. First, the end users enter their size in an app with pictures of themselves with relevant data that determines their body posture. Then the AI calculates all of their body sizes, postures and makes a calculation of their body shape 100 accurately. Then the AI software gathers data from the ...

Oculur is fire-fighting equipment that integrates the sensor into the mask and the water jet nozzle. The collected data is displayed by AR, and the mode will switch from AR to VR when the visibility is poor, providing all-terrain 3D depiction. It can also do AI calculations by collecting the temperature and high temperature distribution data to predict flashover. The thermal imager can recognize the position of the waterline, the angle of the water jet nozzle and the trapped people. The sensor on the nozzle head can provide its precise operation. Oculur provides an effective means of ...

Tests on anchovies show that when plastic is mixed with salt water and begins to disintegrate it releases an odor which is similar to krill. The enticing smell sets off foraging and feeding behaviour in fish, causing them to eat the debris, believing it is food. Previously scientists thought that fish were ingesting tiny particles of plastic by accident when they were hoovering up floating pieces of plankton or krill. But the new study suggests the problem is even more serious because fish are actually attracted to the plastic.

A recent study estimated that nine in 10 of the world’s seabirds now have pieces of plastic in their guts, mainly through eating fish which have ingested plastic. A recent ...

We have developed an integrated air quality monitoring UAS which also has collision avoidance technique to avoid collision with real time obstacles while monitoring. We have used an ultrasonic sensor for collision avoidance and mq135 for air quality sensing. We have developed a program for displaying the pollution gas availablity in percentage instead of ppm.

An anti collision system is essential for safe flight of the drone. It gives a simple solution for obstacle detection and collision avoidance in UAVs. The obstacle is detected using the ultrasonic sensor (HC-SR04).

Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on ...

Supersonic flight over land is currently severely restricted because sonic booms created by shock waves disturb people on the ground and can damage property. In 2022, NASA will begin validation tests of its X-59 Quiet SuperSonic Technology (X-59 QueSST) aircraft, which is anticipated to produce a soft “thump” rather than a disruptive sonic boom. To help achieve this milestone, NASA researchers have developed an innovative approach to capturing images of shock waves emanating from aircraft in supersonic flight. They will use these images to study shock waves as part of the effort to make sonic booms quieter and open the possibility of overland supersonic flight. In addition, this technology will enable the study of flow phenomenon for other systems, ...
