12W net power wireless power IC

10.01.2015

Toshiba introduced the TC7765WBG and TB6865AFG Enhanced Version chips, which perform the functions of a receiver and transmitter in wireless power systems that comply with the Qi LP 1.1 specification. The feature of this chipset is high power - about 10W. Evaluation samples of the TC7765WBG and TB6865AFG Enhanced Version should appear at the end of this month, and the manufacturer expects to start serial deliveries in June this year.

The TC7765WBG implements control functions in hardware, which Toshiba says eliminates the need for software implementation for wireless charging system developers. The TB6865AFG Enhanced Version transmitter is controlled by an integrated ARM Cortex-M3 core.

The transmitter is designed for an input voltage of 19 V. The receiver output voltage is 7-12 V, the maximum output power is 12 W. Applications for the chipset include smartphones, tablets and mobile device accessories.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Rockets five times faster than sound 03.02.2020

The US Department of Defense announced the upcoming test of four new hypersonic missiles capable of five times the speed of sound in flight.

Assistant Secretary of Defense Mike White said that by the end of 2020, the department intends to carry out at least four test launches of prototype hypersonic missiles, which should reach speeds five times faster than sound and maneuver in flight.

The head of the Pentagon, Mark Esper, called hypersonic weapons the key elements of the "great confrontation" with potential adversaries. Another five billion dollars will be allocated from the budget especially for these purposes. Of particular concern to the US military is the fact that China has carried out 20 times more hypersonic tests than the US, not to mention the success of the Russian military-industrial complex.

"This year will mark a new level of development of our weapons," the US Secretary of Defense promised. "We have plans to launch prototype hypersonic land, sea and air-launched missiles," Esper added. Mark Lewis, head of research and development at the Pentagon, added that "we must be willing to fail and learn from experience" in order to achieve success in the field of hypersonics.
