Recently, we often see prototypes or concepts of the devices based on the use of cutting-edge technologies and the latest achievements of science, by which blind people and people with sight disabilities gain the opportunity to “see” the environment
The closest to mass production of such a device is a device Virtual Cane, which using the principle of sound sonar, allows its users to “see” physical objects at a distance up to 10 meters. The device is composed of a emitter, which emits a stream of inaudible sound waves that are reflected from objects and carry back information about the size and the distance to the object. The system informs the user of the vibration oscillations, the frequency and intensity of which depends on the size and distance of the object.
FIELD MACHINE
Dream-the idea of making a car, even simple, like buggy, appeared in his teenage years, when machines were in short supply. But for many UNDERSTANDABLE reasons (had neither the experience nor the tool nor the means) she could not at that time be done — and ended only with drawings on paper. Over the years the opportunity came to build, and the boyish idea has revived in my mind. On the profile of their work by this time, I’m already quite versed in the device of conventional cars, which helped me during the implementation of the project.
Our dictionaries, even technical, somehow paid attention to this type of machines is buggy. But with the current accessibility to Internet resources was not difficult to see and understand what constitutes a real cross sports or recreational vehicles called “buggy”, which translated to English means “bug” or “flea”. And in fact — this is the machine for driving off-road over rough terrain or desert the coast.
LENSLESS MICROSCOPE
Experts from the American University of California, which is located in the city of Los Angeles, has developed a unique lensless holographic microscope. It is expected that the novelty will find application in the diagnosis of diseases of the intestine.
THE GLASS ON THE CEILING
A hole in the ceiling with wires to connect the chandelier is not always used, especially in popular today posted the lighting from different lamps, sconces and floor lamps. The easiest way to decorate the place with white plastic cups disposable, elastic bands and buttons.
HOLD THE STRIPS
Knife planer should have a perfect sharpness, so then it has to be sharpened. It is usually the abrasive on a flat block, which strives to glide along the table, from which straying to the required angle.
CDS
Since 1981, these disks began to advance and now it is not only a device for storing information for computers, and discs with your favorite music or your favorite movies.
And here is how to make these disks on an industrial scale and how they put it on these discs says this video.
CD-ROM (eng. Compact Disc) — optical storage medium in the form of a plastic disk with a hole in the center, the process of recording and reading of information is carried out with a laser. Further development of the CD-ROM became a DVD.
THE CAR-ROBOT FROM GOOGLE
Google does extensive testing of vehicles-robots that can move independently.
The representatives of company Google announced that the company conducts extensive testing of vehicles equipped with Autonomous control system, which will allow these cars on their own, without human intervention, to move on the roads in normal traffic. These tests are carried out on the intercity roads in the state of California, now these cars do run on the route with a length of 560 kilometers from the town of Google in mountain view to their headquarters in Santa Monica.
SOLDERING WILL BE MORE CONVENIENT
Metal “crocodile” attached to the soldering iron stand, will simplify the work when joining the two parts: it is held
DRYER TWO FLOORS
In boxes modern kitchen tables for knives, forks, and other instruments used in plastic box magazine with relevant partitions — compartments.
