Alcohol lock
The alcohol lock is an in-vehicle detection device. The driver exhales the alcohol detector equipped with the alcohol lock. After the instrument tests that the driver does not drink alcohol, the alcohol lock will be turned on, otherwise the car cannot be started. Sweden, Belgium and other countries stipulate that drivers who have been punished for drunk driving have been forced to install alcohol locks.
Alcohol detector
Italian scientists have developed a new in-vehicle alcohol detector called "Angel." When the alcohol concentration in the gas exhaled by the driver exceeds the standard, the detector will give a beep warning. If the driver does not stop, the detector will automatically issue commands through the onboard computer, forcing the car to fail to start or gradually stop driving. New Mexico, USA, has also developed a skin contact alcohol tester that emits a beam of light to the driver's pulse and uses reflected light to analyze whether the alcohol content in the blood vessels under the driver's arm is excessive.
Anti-drunk driving mobile phone
Mobile phone manufacturing technicians in Japan and the United States have developed new mobile phones that can prevent drunk driving by using an "angel" detector. The phone has a small alcohol sensor that connects the sensor to the phone's data transmission system. Once the driver drunk, the alcohol sensor in the phone can detect the alcohol content of the driver's exhaled gas very sensitively. This type of mobile phone is mainly used to help bus and taxi companies to determine whether the driver can drive safely.
Laser detection
Experts from a laser company in Petersburg, Russia, invented a laser alcohol detector that can remotely detect whether a driver has drunk or not to deal with drivers who do not cooperate with the police. The detector emits a special laser that can detect the air inside the vehicle through the windshield. If the alcohol content in the air in the car exceeds one part per million, the instrument will alarm according to the feedback signal.
For esports headsets, USB jack is used, the traditional 3.5mm headphone jack design does not appear acoustic positioning sense, pay more attention to surround sound, design field is different. Wired Game Headphones definitely have lower latency than Wireless Gaming Headphone for Gaming Headphones. Usually use magnetic ring shielding, tensile line design.
Common esports headsets use an all-inclusive design,which has the advantage of isolating ambient noise.The headband part of the earphone will be different from each type of earphone.The strength of the headband will determine whether it will compress the head after wearing, whether it is breathable and other details.
Common esports headphones will be equipped with switch adjustment. When choosing, you can give priority to products that support 7.1 sound channel, consider supporting light switching, and consider supporting acoustic positioning function. Usually tap earphones will also come with a microphone design. Consider models with high sensitivity and acoustic noise reduction.
The online esports headphones are mainly USB ports, and the independent sound card design is mainly used to create virtual sound effects and positioning effects. The use of esports headphones will inevitably appear cool light effect, headset light, microphone light, RGB light belong to the current mainstream design.
