Wireless LCD TV by SHARP

23.04.2003

Sharp has announced a new line of wireless LCD TVs.

The release of such devices is gradually becoming a good tradition - the market is growing, and the absence of wires is becoming, as they say, "a sign of good taste", therefore, an increasing number of manufacturers are paying attention to this aspect. The first model of the new line is called AQUOS LC-15L1 and is a 15-inch LCD TV.

It is a stand-alone device powered by a built-in lithium-ion battery. The AV signal is transmitted from a base station equipped with a built-in receiver; transmission is carried out in the frequency range of 2,4 GHz. Sharp plans to start selling new items from May this year at a price of about $1400.

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, ... >>

Laser Internet for Africa 14.11.2020

Alphabet's Taara has entered into an agreement to deploy a network of laser internet communication stations in sub-Saharan Africa.

Today, the main way to connect cities and other settlements to the Internet is underground cables, but there are many areas on our planet where it is unprofitable or even impossible to lay them for various reasons. In this case, wireless Internet can help - from mobile to satellite, but satellite communications are still very expensive. Some companies believe that in this case it is possible to place signal repeaters on stratospheric balloons or high-altitude drones.

Others, such as Taara, backed by Econet, are suggesting the use of a laser, which can transmit data much faster than radio. As part of a pilot project, engineers are going to develop communications in sub-Saharan Africa - primarily in Kenya. Separate sections of the fiber-optic network will be connected with a laser in places where laying a cable is difficult.

These include, for example, rivers and national parks, as well as areas where armed groups are active. As conceived by the developers, the technology will provide speeds of up to 20 gigabits per second with a distance between stations of up to 20 kilometers. To do this, a pair of infrared laser transmitters must be placed at high altitude - on the roofs of houses or specially built towers. A line of sight must be maintained between a pair of transmitters.
