Smart watch will monitor the quality of hand washing

28.06.2020

Apple has introduced a new operating system for smart watches Apple Watch - among the features of watchOS 7, hand washing control has also appeared.

A new feature was added, including taking into account the coronavirus pandemic that has swept the planet. The gadget on the hands will be able to control the correctness of handwashing, or more precisely, it will indicate to the owner of the device the minimum required duration of handwashing.

According to Apple, motion sensors, a microphone and machine learning on the Apple Watch will be used to implement the new feature, which, based on the sounds and characteristic movements of the watch, will be able to recognize that a person has begun to wash their hands. At this point, a 20 second countdown timer will automatically start. If the person has finished washing before the time limit expires, Apple Watch prompts you to continue washing immediately.

The company explained that the smart watch will be able to automatically remind you to wash your hands when the user returns home from the street. In addition, statistics on the frequency and duration of handwashing will be displayed in the Health app on iPhone. There will also be recommendations from experts on how to wash your hands most effectively.

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, ... >>

New camera series from CANON 10.02.2004

A new series of MV700 camcorders with 800,000-pixel CMOS sensor has been released by Canon.

Despite the almost twenty percent reduction in physical volume, the new camcorders have retained a general external resemblance to the previous line - MV600. The series includes four models: MV750i with 22x optical zoom, MV730i with 20x and two models with 18x optical zoom - MV700i and MV700.

The MV750i and MV730i models have a so-called. "progressive shooting system" - the ability to take still pictures during video shooting and save them in JPEG format to an MMC or SD memory card. The MV750i features a Super Night mode with LED for shooting in total darkness, and a Night+ mode that allows you to turn the LED on and off as you shoot.

All models have a sound filter that removes the noise of the mechanical part of the camera. The new AIF4 DSP chip has replaced the analog AIF3 chip of the MV600 series camcorders. Automatic adjustment of the recording level (ALC / Automatic Level Control), the speaker built into the drive prevents sound distortion when the maximum volume is set.

Models MV750i, MV730i and MV700i are equipped with an analog input and an A/D converter.
