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 ... >>

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. ... >>

ASUS RT-AC3200 3200 Mbps Router 06.06.2014

ASUS introduced the ASUS RT-AC3200 router with support for data transfer with a total speed of up to 3200 Mbps. The Broadcom 802.11ac Multiple-Input, Multiple-Output (MIMO) technology with six spatial streams used in the device allows you to provide Internet access in a multi-user environment at maximum speed.

SmartConnect technology allows the device to increase Wi-Fi performance by up to 200% by automatically selecting the ideal band for network clients based on their location and needs. And thanks to the support of AI Radar technology, the router automatically adjusts the radiation pattern of its antennas depending on the characteristics of the surrounding environment, emulating a directional signal.

According to the company, Ai Radar technology shapes the signal in such a way as to guarantee maximum radiated power for the client: a weak omnidirectional signal is transformed into a stronger, more directional one, while improving channel throughput.

The ability to operate the device in two frequency bands of 2,4 and 5 GHz at the same time allows you to optimize performance for multi-tasking at the same time, such as surfing the Internet and streaming HD content.

The ASUSWRT interface provides simple and reliable network management with the ability to set up in as little as 30 seconds.
AiProtection, developed in partnership with Trend Micro, provides protection against external attacks and maintains complete confidentiality of work.

The ASUS RT-AC3200 router is equipped with six external antennas, USB 2.0 and USB 3.0 ports, as well as four RJ45 connectors for connecting local computers on the LAN network and one WAN port (RJ45 connector).
