A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Apple phones will be able to fall like cats 04.04.2013

The US Patent and Trademark Office (USPTO) has published a patent application from Apple that describes ways to minimize damage when a phone is dropped, according to the Apple Insider Blog. Apple proposes to teach the phone's system to detect when the device is in free fall. For this, built-in sensors can be used - a gyroscope, an accelerometer, GPS, and even a camera. If a fall condition is detected, the system will take action to mitigate the damage.

One of these measures is the rotation of the device in the air. This will "ground" the phone on its least vulnerable side. In this case, the device will not touch the ground with the screen, but, for example, with the side panel. A gas cylinder or a center of gravity shift mechanism can be used to rotate the apparatus. Cats have similar abilities: when falling from a height, they reflexively turn their backs up and land on their paws.

Other measures described by Apple include "wings" that slide out of the body of the device and clips on the headphone and charging cables. "Wings" allow you to slow down the fall of the phone. Clamps prevent the cable from falling out of the socket: if the device falls, it will hang on the wire.

The patent application says that the development can be used in the iPhone, as well as in other electronic devices - smartphones, tablets, players, cameras, and so on. Note that the technologies described in patent applications are not always implemented in life.

Other companies are also developing fall protection systems for mobile devices. So, at the end of December 2012, the head of Amazon Jeff Bezos (Jeff Bezos) received a patent for "air cushions" for the phone. According to the principle of operation, they are similar to the pillows that are used in cars.
