MOTOROLA taught TVs to understand human speech

16.06.2004

With the help of a small company, AgileTV, Motorola has redesigned its DCT2000 cable TV set-top box so that it can now be controlled by voice.

To tell her something, it is not necessary to shout at the whole apartment. To do this, you can use the microphone built into the remote control. The DCT2000 program is capable of handling approximately 100 words and phrases in multiple languages ​​and understands simple command combinations. For example, for the phrase "Find the Sopranos", the prefix will display a list of channels on which the series "The Sopranos" is or will be on.

Before releasing the updated DCT2000 for sale, it was tested for more than a year among American cable subscribers. "Our users who have tried this feature have given it a high rating. Many of them have even discovered interesting channels they didn't know about before," says Jim Faircloth, CEO of cable TV provider USA Media.

Generally speaking, the desire of cable operators to provide customers with new opportunities has led to the development of a voice control system.

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 ... >>

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, ... >>

Life is born at the same time as the planet 11.09.2012

Life is built from a set of complex organic molecules, including sugars. A team of astronomers led by researchers from the Niels Bohr Institute have discovered sugar molecules in the gas surrounding a young star. This amazing discovery may indicate that even during the formation of the planets, the elements of life already existed. The results of the observations were published in the Astrophysical Journal Letters.

A new star and a disk of dust and gas rotating around it - the future planets - were observed using the modern large international telescope ALMA, located in northern Chile. Among other things, astronomers also wanted to examine the gas for the presence of water vapor and understand the chemical composition of complex molecules. In a protoplanetary cloud of gas and dust, scientists have found glycolaldehyde, the simplest form of sugar. This is one of the building blocks of RNA.

Initially, the temperature of the gas and dust cloud is very cold - only ten degrees above absolute zero. Therefore, simple gases such as methane and carbon monoxide settle on dust particles and solidify like ice. Here they behave differently than in the free state - they can bind to each other and form more complex molecules. When a star forms in the center of a cloud of gas and dust, it radiates heat and heats the particles of the cloud rotating around it to about room temperature. Chemically complex molecules evaporate from solid particles like a gas. The radiation of this gas is observed by astronomers.

The observed star is located at a distance of only 400 light-years from us - is, on an astronomical scale, practically, our neighbor. The power of modern telescopes is already enough for scientists to study the gas in detail and see in it, in addition to sugar molecules, signs of other complex organic compounds, including ethylene glycol, methyl formate, and ethanol.

Astrophysicist Jes Jørgenson, associate professor at the Niels Bohr Institute and the Center for Star and Planet Formation at the University of Copenhagen, says the discovery has shed light on the origin of life on planets. Potentially new data, he says, means that the harbingers of life could have arisen in stars long before the formation of planets.
