In a vast range of car alarms has recently introduced a good system Mongoose Duplex 3D models with the function of a pager device, remote audio message to the key FOB that the car owner of unauthorized door opening, engine start, shock the body, etc., a Distance alert in the face of massive urban development (on example of Saint-Petersburg, Russia) not less than 300 m. In the daily operation of the alarm system with a pager is convenient because the alarm comes on, the bidirectional remote control unit (RCU) is a key chain held by the owner of the car (except for a loud audible alarm in the vehicle which can be reprogrammed for quiet mode). Thus, there is no need to jump to the car or to the window each time it is triggered car alarms, worrying for his “swallow” (it is known that the set of sound signals of various alarm systems is no different variety). If it works it is “your” alarms — this will be seen by the alarm on your remote-the keychain remote, and the flash indicator LEDs will indicate a specific area of the triggered zone of protection. It agree, it is convenient.
In the summer of 1970, US spy satellites have recorded the emergence of a new aircraft on the airfield Flight research Institute. This information reached the command of NATO, and NATO has assigned him a codename “Betfair”, which translated to English means “backfire”.
Has long been noted that the viewing of slides, movies, TV shows, as well as any other visual activity (reading, drawing, and examined under a microscope), in unfavourable lighting conditions causes a large overvoltage of view.
Paper is the most affordable and “compliant” material for the manufacture of all kinds of toys — from boats-boats and pigeons until such unexpected figures as a jumping frog, about which we want to telling detail: how it is folded from a sheet of paper and through which it becomes movable.
In the manufacture of printed circuit boards have to drill a lot of holes. This is best done on a drill press. But many radio Amateurs it is? But it is not so difficult to do.
Simultaneously with the design, testing and deployment of serial production of light anti-tank self-propelled artillery installations (SAU) on the chassis of cars and armored personnel carriers (see “modelist-Konstruktor” No. 1, 2002) in the United States began to create similar military vehicles on tank chassis. In September 1941, the weapons Department was issued an order for the installation of the ACS 3-inch antiaircraft gun M3.
In the manufacture of personal watercraft, hidrocaribe and other small-tonnage vessels to protect the surface from moisture and make the case the mechanical strength is widely used fiberglass. However, faced with the complexity of the processing surfaces having a large area (an average of about 8 m2). In this rational use of mechanized tools (electric drill, grinding machine, type “Electra” etc.).
To fly like a bird, the strength of your muscles, very tempting; dreamed about it many of our ancestors. Already in the XV century, when on flights in the modern sense could not even dream of such a machine designed by Leonardo da Vinci. Unfortunately, he was not able to implement their ideas. And only today, after five centuries, people have achieved the first real success.
In the footsteps of virtually every information, published under the heading “ENEA — young innovator”, the editor receives many letters. On the envelope address NTTM, young innovators, enterprises, construction companies, farms, and all of them interested in more information about printed in the journal innovative developments. And United by the desire to apply them to achieve a new increase productivity, improve technology, product quality.
