Foldable UV Sterilizer

30.11.2020

Electronics and accessories manufacturer Moshi has launched an original Kickstarter campaign in the spirit of our time. The company has developed a foldable UV sterilizer that can be carried around and used to disinfect small items.

The device is slightly smaller than an A4 sheet and, when folded, has a thickness of only 2 cm. To prepare the sterilizer for work, you need to unfold it and connect it to the network via USB-C. Any smartphone, glasses, pens and similar trifles will fit inside. Moreover, it is enough just to put objects in the "box" - the design is made in such a way that UV-C also falls on the lower surface. A complete disinfection cycle takes 4 minutes and does not require any user participation.

LEDs were used as a light source. They should be enough for at least 10 years of work. Inside the case there is a UV indicator that reacts to radiation - it can be used to judge what "portion" of light the objects inside received. In two weeks, the project has already collected a much larger amount than was necessary for the launch.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Sony CXD5600GF and CXD5601GG GNSS receivers 25.02.2013

The Japanese company Sony announced the release of chips CXD5600GF and CXD5601GG, realizing the functions of receiving signals from satellite navigation systems (Global Navigation Satellite System, GNSS). According to the manufacturer, they are characterized by the smallest power consumption in the industry - only 10 mW. At the same time, the CXD5430 GNSS module for mobile devices is introduced. Deliveries of new products will begin in June this year.

The popularity of applications that use GNSS information is constantly growing. These include navigation, marking photographs with data on the shooting location, saving routes traveled. GNSS reception is increasingly available on mobile devices, including smartphones, tablets and cameras. However, the high power consumption of receivers stands in the way of the widespread use of global positioning services, with the active use of which the autonomy of mobile devices decreases.

By applying numerous measures to reduce power consumption, including the development of new circuits based on know-how in the field of receive circuit design, as well as experience in creating advanced power management circuits for individual chips, Sony specialists were able to overcome this limitation.

An important feature of the new chips is a new architecture for the interaction of individual blocks. The receiver receives not only GNSS data, but also data from numerous sensors such as accelerometers, gyroscopes, and magnetic field sensors. This helps to refine and complete position information in conditions where satellite signals are weak or absent.

Chips work with five navigation systems: Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), Quasi-Zenith Satellite System (QZSS), Satellite-Based Augmentation System (SBAS) and Indoor Messaging System (IMES).
