Desktop mobile phone

08.07.2005

The Czech electronic company "Yablotron" has launched the production of a desktop cell phone GDP-02.

It is intended for older people who want to use all the services provided by cellular communication, but do not need the portability of a telephone set. In addition, they hardly get their fingers on the tiny keys of an ordinary cell phone and have difficulty seeing the numbers and letters that appear on a miniature screen.

The GDP-02 has a large swivel screen, conventional number keys and a full set of alphabetic keys arranged in the same order as on a typewriter or computer keyboard. This makes it easy to send CMC messages. The phone has a memory for 200 numbers, it is powered by the mains, but it also has a backup battery.

The device can also be used where the telephone cable cannot reach, for example, in the country. In addition, it allows cellular operators to compete with wired communications: in Western Europe, many subscribers give up regular telephone numbers, but at home they would like to continue using the convenient desktop device.

Something similar, but with other purposes, began to be produced by the French company Epsi-Fon. This is a cellular set-top box with a jack for connecting a regular phone and with a directional antenna. The prefix is ​​intended for residents of rural areas in developing countries where there is no conventional telephone network.

The nearest cellular telephony base station can be 32 kilometers away, the main thing is that there is a direct line of sight (this is possible in the mountains or when installing an antenna on a tower - one for the whole village). The set-top box is powered by a lead battery, which can be recharged from the mains, from solar panels or from a bicycle generator.

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, ... >>

Flexible electronics with variable elasticity 28.12.2012

Swiss engineers have learned how to create composite materials with variable elasticity, which can be useful for creating flexible electronics. The work of scientists was published in the journal Nature Communications, and its summary is given by LiveScience.

Creating elastic electronics requires protecting those parts of the device that cannot be stretched, such as integrated microchips. At the same time, the direct connection of brittle and elastic components leads to the fact that when stretched, such devices are torn at the junctions.

Swiss engineers proposed to solve this problem by creating a material with elasticity that changes smoothly from point to point. To do this, they used a composite material - polyurethane with filler. By varying the amount of filler, the authors could make different parts of the material more or less elastic. At the same time, the mechanical properties in different parts of the same material differed by five orders of magnitude.

As a prototype, engineers made an elastic bandage with an integrated LED that could stretch more than three times. The LED was surrounded in the device by a zone of low elasticity, which, when stretched, prevented damage to it.

The authors believe that such materials can be useful not only for creating flexible electronics, but also for prosthetic tendons, which also have variable elasticity. Recently, Japanese engineers introduced a fabric with integrated LEDs, which, like the new material, was flexible, but could not stretch.
