(Original title: Machines know more about humans? Dolby Laboratories uses biosensors to understand how humans watch video reactions)
According to foreign media reports, Dolby Laboratories is currently using biosensors to test human reactions to video programs. In a room with three screens and a dozen speakers, a female wears a 64-channel EEG cap (this is a biomedical cap that measures the electrical activity of brain neurons). She wore a tracker on her wrist to measure her heart rate and galvanic skin reaction. A pulse oximeter was attached to her fingertips. In the other room, a thermal imaging camera was set up to observe the changes in her skin temperature.
Dolby Labs Chief Scientist Poppy Crum said that Dolby is trying to better understand the human experience with video and audio. The company initially began researching human physiological responses to video and audio in 2012 and created a complete biophysical laboratory in 2015. The processing and analysis of these raw data can help the media make the most appropriate decisions.
KNLN6-63 Residual Current Circuit Breaker With Over Load Protection
KNLN6-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
