Touch keyboard with Bluetooth

23.12.2001

Senseboard has developed a device that combines sensor technology with an artificial neural network that can accurately track the movements of the fingers of a typing person. Representatives of the Swedish company believe that the keyboard simulator they have created will solve the problems of mobile computer users who no longer have to poke on tiny buttons.

The device captures finger movements when pressed, and precise measurements allow you to determine which keys a person wanted to press when typing. Sensors made of rubber and plastic are connected to the user's palms so as not to interfere with the movements of the fingers. Using Bluetooth technology, information about the "printed" is transmitted wirelessly to a computer, where a text editor analyzes the signals and turns them into text. In addition to the error correction system, the device has a "pause" function, which allows a person to eat, drink and perform any other work with his hands without removing the sensors.

Senseboard says the device will be compatible with most PDAs, mobile phones and laptops and will sell for around $150. USA expected in March 2002.

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, ... >>

A metallic substance that does not conduct heat when an electric current is passed 29.12.2019

Researchers from the American National Laboratory at Berkeley have discovered a new substance that, being in a metallic state, conducts electricity well, being, at the same time, a thermal insulator. This feature of this material can be very useful in some areas, however, it fundamentally breaks all established principles and understanding of how electrical conductors work.

The properties of a substance discovered back in 2017 violate the Wiedemann-Franz law, according to which the thermal conductivity of a conductive material is proportional to its electrical conductivity. It is in accordance with this law that things such as electric heaters, electromagnets and electric motors become warm and even hot during their use.

The substance detected is vanadium dioxide (VO2), a material that under normal conditions is a transparent dielectric. But when the temperature rises above 67 degrees Celsius, this material passes into a metallic conductive phase. "The unusual properties of vanadium dioxide destroy all our understanding derived from physics textbooks," the researchers write. "This discovery is of great importance for understanding the behavior of electrons in some materials."

In order to understand where such bizarre properties come from in vanadium dioxide (thermal conductivity, which is 10 times less than the value determined by the Wiedemann-Franz law), scientists studied how electrons move in the crystal lattice of this material. And the reason for this was the unusual synchronization of the movement of all electrons. "Electrons inside this material move all together as a fluid flow, and not as separate particles, which is the case in other metallic substances," the researchers write. other materials."

In their research, scientists began to introduce various additives into vanadium dioxide and see how this would affect the properties of the material. The addition of tungsten made it possible to lower the transition temperature of the material to the metallic state and to increase its thermal conductivity. This will allow, for example, to create cooling elements that will start working only when the temperature of the cooled object exceeds a certain threshold.

The new material has another unique property - under normal conditions, this material is transparent in all light ranges, but at temperatures above 60 degrees Celsius, it begins to reflect infrared light, remaining transparent to visible light. Thanks to these properties, vanadium dioxide with some additives can be used as a coating for "smart" windows that can lower the temperature in a room without the need for air conditioning.
