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. ... >>

Lawn mower controlled by smartphone 23.04.2014

For the next summer season, Robomow has prepared a new line of robotic lawn mowers. Models are distinguished by a unique feature - support for remote control using a smartphone.

Models RC304, RC306, RC302, (for small areas) and RS630, RS622, RS612 (for large lawns) are designed for use in gardens up to 3000 sq. m. and are distinguished by a unique feature - support for remote control using a smartphone.

In order to control the lawn mower while sitting in a summer lounger, it is enough to install a special Robomow The App app on your smartphone that supports iOS and Android. Using the application, the user can remotely change the settings of the lawnmower or change the schedule of its operation.

Thanks to the mobile application, the entire process of user interaction with an automated lawn mower fundamentally changes. The difference between the new Robomow models is that they are equipped with larger displays and enhanced functionality. Before using the lawn mower, the owner needs to go through a simple product registration procedure, and then complete the initial setup by following the step-by-step instructions available.

The Robomow The App smart app interface is intuitive and allows you to completely change or partially adjust the mower's schedule. At any time, the user can stop it, change the current settings, or even manually exclude from the working area the area where, for example, garden furniture has recently been placed.

Robomow The app works with iPhone 5, iPhone 4S, iPad mini, iPad 3 and iPod touch (5th generation) and devices running Android 4.3 and higher. The lawnmower communicates with the Bluetooth Smart interface, also known as Bluetooth Low Energy.

Robomow lawn mowers from the new line can be purchased at premium gardening equipment outlets. The prices recommended by the manufacturer for retail sale range from 1000 to 3500 USD.
