Recently, scientists at the University of California, Berkeley, are trying to replace traditional passwords with biometric sensors. They have successfully created an EEG scanner similar to traditional headphones, which will be based on the user’s Brainwaves are authenticated to ensure uniqueness.
The research team said that the "headphones" are cheaper than other similar devices. Consumers can enjoy a pair of Bluetooth headsets plus a brainwave scanner for only $199. After a lot of experimentation, the team members said that the scan pairing was performed according to the radio wave of each user, and the system error rate was less than 1%.
CT For DC Immune Electricity Meters
Performance
â—Power frequency insulation strength:The insulation between the primary winding and the secondary winding and the ground part of the CT can bear 4kV power frequency voltage for 1minute
â—Interturn insulation strength:The secondary open circuit, the primary winding through the rated current 1min, no inter-turn damage in the transformer
â—The deviation is better than the industry standards and national standards
DC resistance current transformer has standard mounting hole and high precision,seals with epoxy and uses ABS,PBT,PC flame retardant plastic shell,.It`s temperature resistance >85℃.
