Chinese scientists from Tsinghua and Tianjin Universities have made a breakthrough in the field of brain-computer interfaces (BCI). They have created the world's first bidirectional adaptive system, which significantly increases efficiency and paves the way for practical applications. According to their research, the developed system is up to 100 times more efficient than traditional BCI....

Recordings from Sunell DVR can be ripped in several ways. The first is to use the local recorder interface – all you need to do is connect a USB flash drive to the device. Another is to use a web browser or CMS application.

The transmission of DVB-T2 and DVB-S/S2 signals via fiber optics enables the efficient transmission of television signals over long distances with minimal loss of quality. In the case of DVB-T2, the terrestrial television signal is converted into an optical form and transmitted via a single-mode optical fiber to optical receivers, which eliminates the attenuation problems associated with traditional transmission based solely on 75 Ohm coaxial cables. Similarly, the DVB-S/S2 signal, which is nor...

The 2-Wire HD video intercom system from the EY series is the perfect solution when upgrading an old intercom or video intercom system that uses a straight or paired cable as the communication bus. In this system, communication and powering of devices such as door stations or monitors is done using DS-KAD7060EY G74828 and DS-KAD7061EY G74830 distributors. This is a Plug & Play system, which, once the devices are properly addressed and configured using the switches on their backsides and powered...

Reflectometric measurement provides a range of information about the measured line. One of the measured parameters is the so-called reflectance of a given incident analyzed in the case of reflective elements: connectors and mechanical splices among others. By definition, reflectance is the ratio of the power reflected by an object to the power incident on that object, expressed in decibels. Since the power of the reflected signal will always be less than the power of the incident signal, reflec...
