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. ... >>

Samsung U32D970Q UHD Monitor 05.08.2014

Samsung Electronics has announced its flagship UHD monitor, the U32D970Q.

The panel is made on the PLS matrix. The monitor is a professional grade product and is said to be suitable for users whose activities involve working with graphics, photo, video, and design systems. The PLS-matrix provides "perfect image output without loss and distortion."

The U32D970Q is a 31,5" UHD monitor. Its resolution is 3840x2160 pixels. According to this indicator, the panel is equivalent to four Full HD monitors installed side by side, and in terms of the number of displayed colors it exceeds a standard monitor by 64 times.

It is noted that each U32D970Q monitor is individually factory calibrated in 25 zones. The user also has the possibility of self-calibration using special software to correct gamma, backlight uniformity, and white balance.

To connect signal sources, there are HDMI 1.4, DVI-DL interfaces, as well as two DisplayPort 1.2 connectors. When using two sources at the same time, the monitor will output the signal from both devices thanks to the Picture-in-Pictrure function - the image of the small window will be reproduced in its original resolution up to Full HD (1920x1080 pixels), while the main picture will remain in the highest UHD format.

In addition, the innovative Quad Picture-by-Picture function allows you to effectively work with all four connection sources at the same time - using this function, it is possible to simultaneously display images from four devices at once in Full HD resolution.

The monitor is also equipped with a USB hub with 4 USB 3.0 connectors for connecting peripherals.
