Super slim keyboard with magnetic cushion effect

10.06.2014

Super-slim keyboards for laptops and other ultra-slim mobile systems are in increasing demand. At the Computex 2014 event, the Taiwanese company Darfon introduced a super-slim keyboard with an unusual design.

Many people know about maglev trains used in Japan and China. A high-power electromagnetic field lifts the train above the rail and allows the train to develop tremendous speeds. The developers of Darfon applied the same effect when creating the keyboard: an electromagnetic field returns the key after pressing to its original position, holding it there. How convenient this is from the consumer's point of view is a moot point, but without the use of a traditional returnable silicone cap under the key, the entire structure has significantly lost its height.

It is worth noting that the small travel of the buttons has a significant drawback: such a keyboard is not as convenient as a traditional one. However, the manufacturer promises to make life easier for users by adjusting the field strength within three standard gradations. To date, everyone who got acquainted with the development of Darfon at the exhibition is not enthusiastic about the new keyboard.

The company has not yet shared information about a possible laptop manufacturer that is ready to release PC models with a magnetic keyboard. At the same time, Darfon hopes that such systems will appear on the market in the second half of this year.

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 ... >>

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, ... >>

Ultra-compact 2,5mm thick image sensor for mobile devices 20.02.2012

Designers are looking for ways to reduce components used in mobile devices such as smartphones, tablets and laptops. OmniVision has created an ultra-compact 720p image sensor that is smaller than any other sensor on the market.

The novelty received the designation CameraChip OV9724. It features a new OmniBSI+ architecture with 1,4µm photosensitive elements. According to the manufacturer, based on the CameraChip OV9724 sensor, it is possible to create camera modules with a height of less than 2,5 mm. At the same time, the OVM9724 sensor is introduced, similar to the OV9724, but packaged in a proprietary OmniVision CameraCube case.

Sensor format - 1/9 inch. The devices support 720p HD video at 30 fps. When the resolution is reduced to VGA, the frame rate can be increased to 60 fps. It is possible to read the whole frame, the whole frame with reduction and the selected window. Data representation - 8-bit or 10-bit. Necessary image processing functions, such as exposure control and defective pixel correction, are programmed using the standard SCCB (serial camera control bus) interface.

The OV9724 MIPI sensor is housed in a 6 x 4,5 x 2,5 mm housing. Evaluation samples are now available, and mass production should begin in the second quarter. The dimensions of the OVM9724 sensor in the CameraCube are 4 x 3 x 2,5mm. The appearance of introductory samples of this product is expected in the beginning of the second quarter.
