Machine screw-rotor type
Jan 19, 2011
Since the invention of the first car of mankind constantly seeks to introduce a variety of auto-variation in the daily life in order to facilitate the most complex tasks. However, not all inventions are coming into production, as happened with the screw-rotor-terrain vehicles. Despite their potential utility, their use in the home was simply impossible, due to the fact that the support of such units was necessary not to track or wheels, and the sharp horizontal cylinders. On the one hand it is not possible to get bogged down a car or in a quagmire, no matter razmyakshem ground, or even in the overgrown underbrush coast shallow water. On the other hand, the cylinders with twin screws were absolutely useless on the asphalt. "Arhimetovy screws, located on the surface of the cylinder is simply slipped on the asphalt, uttering at the same time an eerie rasp, barely moving the car away.
However, not so long ago in St. Petersburg was created by the project "Transformable screws or Tesh drive. Its initiator and inspirer made inventor Alex Burdin, who as a result of numerous trial and error, managed to make the screw-rotor suitable for travel on public roads. Achieve this was made possible through the combined on one frame of wheel and spiral motion mechanism. Between the turns of the screw-rotor inventor placed the so-called element with variable geometry - rubber sleeve, which in the expanded state allows the vehicle to move in a rolling mode. In this mode, Tesch Drive can roll up until his path does not have any obstacles podvlasnye only screw mode. So, as soon as the route appears loose gravel, deep snow, or other water-ground obstacles, the driver is enough to transfer the car into screw mode. At the same time deflates, the sleeve is pressed against the body of the rotor, and the car starts to go sideways. " In addition, due to a water jet engine such auger has a high buoyancy and can force the major water obstacles.
Once again, the soil becomes sufficiently dense and smooth, we can again move the car in the rolling mode, and switching time is planned to be automated, making the operation of the car extremely easy and convenient. Meanwhile, the prototype switch is carried out manually.
Scope of this vehicle is extremely high. By maneuverability and high cross in both directions, it can be used rescue services, hunting and fishing, and even to take the conveyor as a military transport. After all, Tesh drive than any of the foregoing, features, and enhanced survivability. Even if the flexible element, placed on the cylinders, completely out of order - the vehicle retains the ability to move and leave the danger zone. Hopefully, the domestic industry interested in the invention earlier than the foreign engineers and investors.
Concept of bicycle path in the air
Jan 14, 2011
In an effort to quickly reach a specified part of the city, the road closes traffic jams. But like so without delay to go to a desired point that there is a desire to climb up and reach the goal, rushing to her nonstop. Martin Angelov, with its concept, possibly in the near future will embody the desire into reality. His project, titled Kolelinia, provides an opportunity to go above ground travel arrangements, using a bicycle. Itself to develop a system based on the principle structure of chair lifts, which are equipped with ski resorts. The author claims that it was studying building principle cableway gave rise to his project. The very idea is very ingenious and very simple to implement it. In this system the bike is set in a special chute and wheel attached to a rope. For the safety of cyclists, there is a strap that attaches to the rope. Unlike the developed system of aerial cableway in the fact that there has to make himself a cyclist in force for the movement. Martin Angelov refused to use electricians in your project, to reduce its cost.

Nov 27, 2010
The device is the size of a matchbook secured to the head. It consists of a control circuit, battery, and motion sensors, the parallel channels of the inner ear. The inner ear patient implanted eight electrodes. According to him on the vestibular nerve endings signal, which creates a chip. Thus, a three-dimensional sensation of head movement.
Processor in the use of a unique program that was developed Santina and his team. The principle of operation is quite simple - the device creates a millisecond pulses, which are very similar to the real thing, which must come from the inner ear.
As a consequence, the device is fully simulates the vestibular apparatus, thereby replacing damaged.
As noted by the authors of the project, this is not the first development in this area. However, all previous work with only one channel and one plane of perception of space. The uniqueness of the new device is that it completely replaces the three-dimensional perception of the world and creates an artificial sense of balance, while reacting to the rotation in all three planes in any direction.
At the moment the device has not been tested on humans. Experimental animals are chinchillas, who with the help of huge doses of gentamicin have been damaged cells of the inner ear, which destroys the spatial orientation and the vestibular apparatus. Signs of such violations in this case were: staggering gait, trembling movement, trembling eye movements. The experiments showed that chinchillas have lost the ability to stabilize the eye. After implantation of the device, the animals regained some lost reflexes.
Authors of the project have set themselves ambitious goals. Before prescribing the device for people he wants to significantly reduce its size to make it easier and sealed so that you can install it under the skin, rather than mounted on the head.
Another direction of work on the device, this reduction of interference, which have an impact on neighboring nerves, as well as the creation of stimulating pulses, which are most similar to natural ones.
This invention is still under development, but it can help hundreds and thousands of people affected by a violation of the vestibular apparatus, which is due to the impact of viruses, chemotherapy, the use of large doses of antibiotics, stroke or other head injury. Also, patients are prescribed high doses of gentamicin due to illness, may no longer be afraid of losing orientation in space.
New glasses
The need for bifocal lenses in the near future may disappear and are replaced by a new generation coming glasses. Already established glasses lens through which the objects are clearly visible to any person suffering from any degree of nearsightedness or farsightedness.
Over the years, there are different processes and lenses in the eyes often lose the ability to change shape, and it is necessary to properly configure the focus on close objects. This disease is called presbyopia, or otherwise it is called presbyopia, and this situation should seek a way out, so people started working on the development of optics. Consider this situation - the person to the disease suffered from myopia, while the use of points, he will quickly be able to focus on close or distant subjects a bit. For people aged and created bifocals. The lenses of these glasses are from two lenses, which are located one on top, and the second at the bottom. Upper order to be able to focus on distant objects, and the lower order to focus on nearby objects, but there are different situations where close objects must not be regarded at the bottom and just above, or distant objects at the bottom and it needs to be raised or lowered head, which creates a big problem.
Israeli scholar from Bar-Ilan University, Zeev Zalevsky invented a technique that allows you to create a lens focuses light and well at a distance of 33 centimeters to a distance horizon. For such purposes on a normal lens creates a lattice of 25 circular structures, each has a size of two millimeters, and is 2 concentrated ring, but the exact size of the ring will be different for a particular lens, and it depends on the shape and size, but on average a few hundred microns in width and a micrometer in depth, telling Zalewski.
The rings serve as a displacement phase oscillations of light waves that pass through the lens and simultaneously cause sicken and amplifying the interference. When using a computer model Zalewski created another model that generates reinforcing channel interference, which is perpendicular to the lens of any of the 25 structures. As a result of these transformations, the light is focused axial channel, not the focal point. If the retina is in the area of the channel, then the object can always be seen in focus. In the sequel to confirm their achievements Zalewski, attached to the camera lens of your phone, and also experienced his invention at the twelve volunteers. Shortly based company Xceed Imaging, which perfected the technology. In any new invention has its pluses and minuses, it is also a plus that the person sees well, and the disadvantage is that the adventures of the world through the lens loses contrast. In turn, Spanish scientist Pablo Art from the University of Murcia said that at too high a decrease in contrast, the brain will be difficult to process information coming from the eye, but Zalewski says that those people who wear glasses are not noticed a significant change in contrast as eyes well adapted to the light of low intensity light, and it happens a few seconds. But the brain needs to get used not only to change the contrast, but also by unanimous decision, because the lenses do not move the changing angle of view and, therefore, concentrated between the image circle will be defocused. At the time of movement of the eyeball from one structure to another carved holes appear and the brain fills them and creates the effect of continuity - said Zalewski.
3D printer will allow printing space objects
Nov 19, 2010
According to the staff of this organization, the emergence of three-dimensional space print will significantly improve and facilitate the production of components for space satellites. In addition, the emergence of space to print a few times will reduce the number of cargo flights into space. The main product, which will need to send into orbit, will be the material needed to operate the printer. The important point is that, for the manufacture of parts of the failed printer will use the materials previously sent into orbit. That is, processing of raw materials will occur. This in turn will reduce costs for new parts for the 3D printer.
Departures of people on other planets is not far off. When that moment comes, the new printers will play a role. The fact is the construction of the space base will be possible with the help of materials used in the printer. Raw materials These printers will also help in creating devices for the development of new planets.
Plans of the company Made in Space is really daunting. But, unfortunately, the company is only the first step in the development of print space. Employees have already been made several tests of new printers. Were printed out some of the details of space objects. In further promotion of the company is testing the printer is operating in complete weightlessness. Let's hope that this test will be successful. Indeed, in the case of a positive result of further testing will already take place in outer space.
Slowest cruise ship in the world has become a floating hotel
Nov 18, 2010
Basic structural element of the floating hotel will be flexible "backbone", because of the properties which Morthotel can change their shape to adapt to the weather and more successful and safer fit into the shape of the coastline during the rare stops in ports. To ensure the comfort of living persons on board this floating hotel, it would appear all that equip modern and comfortable cruise ships. To provide passengers with any type of leisure and entertainment spots will be widely represented restaurants, bars, sports and movie theaters, swimming pools. Unusual cruising will remain unforgettable.
Snowbird:Aircraft
That is the name given to this unique design, weighing 94 kg and a wingspan of 32 meters. Through the muscular traction Ornithopter was kept in air 19.3 seconds and flying during this time 145 meters at a speed of 25.6 km h
To disperse Ornithopter was used normal car, which at first hauled construction. Then the rope that Snowbird was attached to the car was uncoupled and the unit moved into a state of free flight, holding in the air only at the expense of their long flexible wings. In order to design set in motion the muscular force pilot who uses cunning system of cables. Emerging horizontal and vertical thrust lead design in motion and keep it in the air.
Snowbird inventor says his creation is perhaps the most significant invention in the aircraft industry over the last decade. Despite the fact that Ornithopter is hardly a practical mode of transport, he embodies the dream of many generations of people - fly like a bird. In order to maximize ease device with a pilot on board, most Reichert had to lose 18 kg, sitting on a rigid diet.
Design, which is the first step in the development Ornithopter was designed under the project Human-Powered Ornithopter (HPO). For the construction of Snowbird were used balsa, polymers and carbon fiber.
Invisible Tree House: Tree Hotel in Sweden
Aug 30, 2010
One of the owners of the house Kent Lindvol said that the mirror wall of the house reflects trees, birds, clouds, sun everything. That’s why it looks like invisible house in the tree. He also said, there is such a film on the mirror which only birds can see. So the birds will not face any problem when flying near the tree house. Human can only see the mirror but the house is not fully invisible for birds. The owner said, he does not want to damage the nature of the forest and to keep the animals moving fearlessly in the forest. Thus he has built such an invisible tree hotel. He further said tourists also can stay peacefully and safely in the tree hotel.
