 Comments on the article

Currently, more and more specialized microcircuits are appearing on the market, which are used in mass-produced devices. In particular, TELECONTROLLI produces several series of miniature circuits used in wireless communication systems (in the ultrasonic, infrared and radio wave range). Such devices can be successfully used in security and access control systems, telecontrol, vehicle traffic control and data transmission. In everyday life, they can be used to protect apartments, cars, as well as for remote control of various devices (opening doors, lighting control, etc.).

These series of microcircuits are complete transceiver devices that are easily integrated into any of the above systems due to their miniaturization and versatility of use. As an example, we can cite car security systems, in which by simply replacing the modules of the receiving and transmitting devices (instead of standard ones), you can significantly increase the range of the system, change its frequency range and increase noise immunity.

We list the main devices manufactured by TELECONTROLLI:

• super-regenerative receivers for various operating frequencies with high-quality resonant systems (the geometric dimensions of the inductors are controlled at the production stage using laser technologies);
• high-quality superheterodyne (AM/FM) receivers for various frequency bands. To improve reception quality, most receivers use specialized frequency synthesizers and quartz resonators;
• miniature radio transmitters using quartz resonators, frequency synthesizers and surface acoustic wave (SAW) filters;
• miniature ultrasonic transceivers;
• infrared transmitters and receivers. In this class of devices, there are also systems that respond to the thermal radiation of biological objects.

All the listed devices are built on the basis of thick-film hybrid assemblies and are designed for different supply voltages. They have the lowest possible energy consumption for their class.

As an example, let's dwell on the electrical characteristics of some devices (see table).

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 Black Silicon for Efficient Solar Panels 20.10.2012 Solar panels convert only three-quarters of the sun's energy into electricity. Thus, to the initially low efficiency, the loss of the entire infrared part of the spectrum is added, which is an unacceptable waste. Scientists at the Fraunhofer Institute have developed a new material for solar cells that also captures infrared light. A material called black silicon is very promising, and recently German scientists managed to double the efficiency of solar cells based on it. Due to the fact that solar panels simply cannot turn a quarter of the energy of the sun's rays into electricity, not only energy is lost, but also the heating of solar panels occurs, which reduces their service life and further reduces efficiency. One way to overcome this problem is to use black silicon, a material that absorbs almost all sunlight, including infrared radiation, and converts it into electricity. Black silicon is obtained by irradiating standard silicon with femtosecond laser pulses in a gaseous medium containing sulfur. During this process, sulfur atoms are attached to the atomic lattice of silicon. In conventional silicon, infrared light lacks the energy to excite electrons and convert them into electricity. It is like a high wall that cannot be overcome in one jump. But due to the inclusion of sulfur atoms, black silicon forms a kind of intermediate levels that facilitate the "jumping" of electrons. By changing the parameters of the laser pulse, the scientists were able to change the height of the intermediate levels and increase the return of electrons to the maximum level. Initially, the developers plan to simply add black silicon cells to conventional solar panels. Tandem cells made of ordinary and black silicon will be only a couple of percent more efficient than conventional ones, but in this way it is possible to upgrade a large number of existing solar panels, which will give a good increase in energy. In the future, black silicon can be used as the main material for the manufacture of solar panels, although this will require the development of special automatic laser systems.
