American radio amateur Nizar Mullani, K0NM analyzed the electrical parameters of a dipole with 90 degree bent ends - a bent dipole.
Fig. 1
It turned out that a 50% curved dipole has a gain of only 0,6 dB less than the "classical" one, and a 40% curved dipole has a wave impedance of about 50 ohms. The proposed shortening method can be useful in constructing various dipole antennas, including wave channels for low-frequency bands.

Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive Touch laptops will become cheaper
22.04.2013
Laptops with touch screens have experienced poor sales since launch. First of all, this is due to too high prices. Until recently, manufacturers have been able to bring only a limited number of touch panels for notebooks to market, due to low product yields. Of course, the price of such scarce devices remained quite high.
According to industry sources, some touch panel vendors have been able to solve most production problems and achieve yields as high as 85%. It is expected that in the third quarter, touchpads for laptops will significantly fall in price, which will positively affect the cost of the laptops themselves. For example, prices for 13,3-inch touch panels will drop to $50.
The largest suppliers of touch panels for laptops are TPK and its subsidiary Cando. The rest of the manufacturers are still actively working to increase the level of product yield. It is interesting to note that in the first quarter the share of touch notebooks in the shipment structure of Sony and ASUS was 15-17%. For Acer, this figure also exceeded 10%. American manufacturers are in no hurry with the introduction of touch models, but, according to industry players, by the end of 2013 they will bring the share of such laptops to 20%.
