A team of researchers from the Department of Physics and the Centre for Quantum Optical Technologies has built an innovative all-optical radio receiver that exploits phenomena characteristic of so-called 'Rydberg atoms' - those in which at least one electron is at a very high energy level. The device is distinguished by its exceptional sensitivity and built-in self-calibration mechanism, and its operation is based solely on laser light power. The results of the research were presented in the re...

In vehicles, additional systems such as a mobile DVR, network devices, LTE routers, communication modules or other systems requiring a constant power supply are sometimes installed. In order to ensure their continuous operation irrespective of the ignition status, ATTE has developed the LVUPS-140-UN1-OF M18725 universal buffer module for use with 12 V or 24 V vehicle installations. Its main task is to ensure the continuity of power supply to network devices - both while driving and when the veh...

Ballast masts are structures designed for the installation of antennas, lighting, signalling or other equipment on roofs and other flat surfaces, without the need to interfere with the structure of the ground. Their stability is ensured by appropriately selected ballast (usually concrete weight plates), which prevents the mast from toppling under the influence of wind or vibrations. Ballast masts are widely used in temporary and permanent installations, particularly where permanent anchoring of...

The diagram below shows a monitoring system for a block of flats based on a Hikvision IP DVR and hybrid cameras ColorVu 3.0 belonging to the Easy IP 4.0+ series. Smart Hybrid Light cameras from ColorVu combine the advantages of traditional cameras and ColorVu series cameras. Traditional cameras have an IR illuminator, which illuminates the scene and enables night-t...

DAC fibre optic cables (Direct Access Cable) thanks to their hard outer sheath can be laid directly in the ground - without the need for additional protective pipes. Such a cable, although resistant to crushing, can be damaged. The most common cause of cable breakage is the use of an excavator or spade....
