Smart headband MOOV HR

20.10.2016

Step tracking is no longer enough for fitness devices. Devices are now getting a means of estimating heart rate and intensity—unfortunately, wrist-worn electronics aren't very accurate. MOOV HR promises heart rate monitoring on a par with the electrocardiogram, the gold standard for assessing heart performance. This is achieved by measuring the pulse from the forehead of the user.

Older versions of the MOOV were worn around the ankle or wrist. In turn, MOOV HR involves the use of a sensor either in a headband (for most cases) or in a swimming cap. The device, unlike the Fitbit or Jawbone, works more as an AI-based coach than just a fitness tracker. The main feature is informing the user in real time about the progress of training. HR can show the user's heart rate in the app either as a beats per minute or as a continuous graph.

Most wearable devices measure the pulse using LEDs: the light is reflected from the skin, and by its change due to blood volume, the device captures heartbeats. Wristwatches are very comfortable, but studies show that the wrist is far from the best place to get accurate heart rate measurements. On the forehead, the skin is thinner, so the received signal is much cleaner and more accurate. High-quality readings can also be taken from the fingertips and ears, but in addition to accuracy, the device must also be comfortable.

The headband must also be more precise due to constant contact with the skin: on the wrist, the device can be attached relatively loosely, and move during hand movements and intense training. Any gap between the sensor and the skin (as well as movement of the bracelet) reduces the accuracy and reliability of the readings. In the case of a bandage, this problem disappears.

MOOV HR is priced at $60 as a smart headband or swimming cap. If the user wants to purchase both options, then they will have to pay $100.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Washing machine from Porsche 25.11.2018

The Japanese company Panasonic turned to the German brand Porsche for help in developing the design of the Alpha premium washing machine.

The design of the washing machine in German is strict and concise. The gray body is made of stainless steel and is equipped with a built-in suspension that dampens vibrations when the machine is in spin mode.

On the front panel there is a color screen, the graphics of which are stylized in the design of the dashboard of Porsche cars. In the spirit of the times, the washing machine is equipped with a Wi-Fi wireless module and allows you to connect to it via the Internet using a special mobile application. It allows you to remotely select washing modes, start the machine, adjust the amount of detergent and receive text notifications at the end of the wash.

The new model is only for sale in China.

The price of the novelty is 2900 US dollars.
