New Toshiba Robot Vacuum Cleaners

29.08.2014

In September, the Japanese corporation Toshiba will start selling new robotic vacuum cleaners of the Torneo Robo series, which are characterized by an improved design and enhanced dust and debris collection capabilities.

In total, the novelties are equipped with 27 different sensors, which include numerous ultrasonic and infrared sensors. They help to identify walls, interior items and various obstacles, including objects made of glass. In addition, thanks to sensors, the robot can maintain a constant distance to walls when moving along them, as well as detect sudden changes in height and prevent tipping over (for example, from a ladder).

New vacuum cleaners received side brushes with extended bristles, which allows you to collect more dirt. The rotating brushes are height adjustable for maximum efficiency in picking up debris and dust on a variety of surfaces.

The new series includes the VC-RCX1, VC-RVD1 and VC-RV1 models. The first two come with a charging dock equipped with a waste container. Thus, during recharging, the dirt accumulated in the vacuum cleaner is transferred to a stationary tank, which ensures a constant suction power.

The VC-RCX1 version also has a built-in camera and Bluetooth wireless technology, allowing you to control the operation using your smartphone or tablet.

The VC-RCX1, VC-RVD1, and VC-RV1 robot vacuum cleaners will cost approximately $1150, $860, and $720, respectively.

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, ... >>

Among the bees, there are also right-handers and left-handers 10.11.2017

Entomologists from the University of Queensland have proven that bees can have an individual tendency to choose right or left when flying. Approximately a quarter of the insects participating in the experiment of scientists turned out to be "right-handed", another quarter - "left-handed", while all other animals did not show preferences.

Studies show that insects exhibit certain behaviors when navigating, such as flying more slowly in narrow passages (perhaps to reduce the risk of injury). In addition, they may have individual inclinations, but so far this has been little studied.

The authors of the new work decided to test two hypotheses at once - whether honey bees will choose a wide path more often than a narrow one, and whether there are “right-handed” and “left-handed” among these animals. The researchers built a small tunnel between the hive and the feeder, in the middle of which there was an obstacle. It was a partition either with a wide and narrow, or with two identical openings. The insects had to fly through this obstacle to get food, while the scientists monitored their behavior. About 100 bees participated in the experiment.

When the size of the holes in the tunnel differed, the bees usually preferred to fly along a wider path - and the larger the difference, the more pronounced this pattern was. However, when the passages in the tunnel were the same, the bees showed individual differences: while 55% of the insects chose the path randomly, flying either through the right or through the left hole, the remaining animals were divided approximately equally into "right-handers" and "left-handers". These bees chose one side time after time.

Additional experiments confirmed the result. In particular, when the bee was forced to fly not through its "own" side - for example, when the "right-handed" bee had to fly through the left, but wider passage - it needed a little more time to make a decision. If the path more convenient for the insect turned out to be simultaneously wider, then it reacted almost instantly.

Scientists suggest that such tendencies may help bees navigate. If there were no “right-handers” and “left-handers” among the bees, then perhaps they would all fly in the same ways, which would make movement difficult. On the other hand, if all insects had such tendencies, it would lead to a similar problem. Divide into three groups, according to the researchers, this is the most convenient strategy.
