Epson Home Cinema 3 and 1040 1440LCD Projectors

08.09.2015

Epson has announced two new projectors for the home. The range of the manufacturer was supplemented by 3LCD models Home Cinema 1040 and Home Cinema 1440.

Both devices are capable of projecting a widescreen image with a resolution of 1920 x 1080 pixels and up to 300 inches diagonally. The devices are equipped with a USB interface and two HDMI ports with support for MHL technology, which allows you to connect compatible smartphones or tablets to the projectors, which will also be charged at the same time.

Home Cinema 1040 and Home Cinema 1440 are characterized by maximum brightness levels of 3000 and 4400 lumens, respectively. The contrast ratio is 15:000 and 1:10. Another difference between the new products is the support for Farouja DCDi technology, which eliminates visual distortion of the picture, increasing its quality. This solution is implemented in the Home Cinema 000 model. It also has the function of dividing the image into two areas in which different pictures or video streams are displayed.

The Epson Home Cinema 1040 will cost $800 and the other model will cost $1700.

Both products will go on sale in September 2015. They will be covered by a two-year manufacturer's warranty.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Fiber optic network as an earthquake predictor 30.10.2017

Earthquakes are one of the most destructive natural disasters. Sometimes even a few minutes of warning about them can be decisive. And now Stanford scientists have come up with an interesting proposal on how to create a truly global network for early earthquake detection.

Now such a system requires the installation of highly sensitive sensors that will measure the slightest tremors that can signal that a major disaster is near. But standard sensors can't cover everything, so a group of Stanford scientists came up with another solution: a fiber optic network.

Fiber optic cables transmit information at almost the speed of light and are used by telecommunications companies around the world. But they are also used by oil and gas companies to monitor small shocks caused by drilling equipment. With such measurements, a characteristic of cables called "backscatter" is needed, with the help of measuring the movement of cables and recording seismic events.

There is a laser at one end of the cable that sends out light. Part of the light hits impurities and defects in the glass walls of the cable and is reflected: this is the "backscatter" that was discussed. The signal received under such conditions can change depending on whether the part of the cable where the reflection occurred was moving, and fixing such signals can give scientists a map of seismic activity over a large area.

Typically, fiber optic detectors are attached to pipes or other equipment, but to detect earthquakes, researchers need loose cables, which is considered almost impossible, as most people think a loose cable will generate too many signals to be useful.

But by using a five-kilometer cable on the campus of the university itself, the researchers demonstrated that optical fiber is suitable for such purposes. With their network, they were able to detect about 800 seismic shocks, including an earthquake in Mexico and two small local earthquakes of 1,6 and 1,8.

This means that scientists can detect earthquakes using the already existing fiber optic network of communications companies. Of course, such cables are not as sensitive as traditional seismometers, but they are much cheaper and provide more area coverage.
