Photo sensor HDSL-9000 for backlighting LCD displays and keypads

10.03.2003

AGILENT TECHNOLOGIES introduced the HDSL-9000 photo sensor, which estimates the amount of light at any time and sends a signal to adjust the backlight in LCDs and keypads.

This reduces the power consumption of batteries and accumulators in devices such as mobile phones, notebooks and mini-computers. The device has a maximum sensitivity at a wavelength of 550 nm (the same wavelength is most sensitive to the human eye). It has a digital sensitivity setting. Produced in a case with dimensions of 1,1x4x3,2 mm.

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 ... >>

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, ... >>

World's largest XNUMXD printed building 18.12.2019

Apis Cor, a XNUMXD construction printing technology company, recently completed what could be described as the world's largest 'printed' building to date. This building, located in Dubai, is the body of an administrative building, it was erected using a single three-dimensional printer, although it is worth recognizing that much of the work was done in the old fashioned way by human builders.

The two-story administrative building has a height of 9,5 meters and a total area of 640 square meters. Its construction was carried out in a completely traditional way, by squeezing a cement mixture through the nozzle of the printer, which layer by layer formed the entire structure of the building. Since the building being erected was quite large in size, the Apis Cor 3D printer was suspended in the air with a crane and could only build one separate room at a time. Because of this, the entire construction process of the building took three weeks.

A fairly large part of the work was done by builders who laid the foundation, installed windows, doors, ceilings and roofs, plus carried out all internal communications. Moreover, people manually filled with concrete those rare places where the nose of a three-dimensional printer could not reach.
