Smart ring from Samsung

30.12.2015

Application #20150370226, filed last June, appeared in the US Patent Office (USPTO) database. It describes a smart ring - an appropriately shaped electronic device designed to control another electronic device, such as a smartphone, tablet or smart TV. In addition, the smart ring can be used as part of a home automation system.

The possibilities of the ring are ensured by the fact that sensors are built into it, allowing you to judge its position. As conceived by the inventors, control using the ring looks like this: the ring leans against the screen of the device and begins to play the role of a control wheel, allowing you to select items on the on-screen menu.

Menu items are customizable. In particular, other devices that the ring can control can be added to them.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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, ... >>

Biodegradable displays for green electronics 04.02.2021

Scientists from the Karlsruhe Institute of Technology (KIT, Germany) have created biodegradable printed displays that can be recycled after use. The new development will help save resources and reduce the amount of electronic waste.

The new display works due to the so-called electrochromic effect of the original organic material. When voltage is applied through conductive electrodes, the material changes its color. Electrochromic displays have low power consumption and simpler architecture compared to commercially available displays such as LED, LCD and E-paper.

A further advantage is that these displays can be produced by inkjet printing in an inexpensive and economical manner. Mostly natural or biocompatible materials are used. Sealing with gelatin makes the display adhesive and flexible so it can be worn directly on the skin.

The display is generally suitable for applications with a short life cycle in various sectors. For example, in medical diagnostics, where hygiene plays an important role, sensors and their indicators must be cleaned or disposed of after use. The newly developed display will not be thrown away as electronic scrap - it can be composted. It can also be used for quality control of food packaging where reuse is not allowed. Digital printing allows you to change displays and adapt them to new devices and applications without the high cost of changing the process. This reduces resource consumption.
