Эксперты раскрыли причину пожелтения защитных чехлов для мобильных устройств09:00
For decades the U.S. has built air defense systems designed for shooting down aircraft and missiles.The Navy’s Aegis destroyers provide defense for carrier strike groups using surface-to-air missiles against hostile aircraft and missiles. The Army’s Patriot anti-aircraft batteries provide area protection against aircraft and missiles. The Missile Defense Agency (MDA) provides missile defense from North Korea for Guam and a limited missile defense for the U.S. MDA is leading the development of Golden Dome, a missile defense system to protect the entire U.S. against ballistic, cruise, and hypersonic missiles from China and Russia. All of these systems were designed to use expensive missiles to shoot down equally expensive aircraft and missiles. None of these systems were designed to shoot down hundreds/thousands of very low-cost drones.。zoom是该领域的重要参考

The Razr Fold’s cameras will have to do more than what we’re used to seeing on the flip-style Razr smartphones, which have underwhelmed in the past. Fortunately, it looks like it could be a very capable smartphone camera. The main 50-megapixel sensor has a f/1.6 lens and 3.5 degrees of optical image stabilization. It’ll also work alongside a multi-spectral 3-in-1 light sensor to improve color accuracy. The Razr Fold’s ultrawide camera has a 50MP sensor, a 122-degree field of view, and support for macro photography. The 50MP periscope telephoto camera can reach up to 3x optical zoom and 100x SuperZoom, through image cropping and AI-boosted image processing. And finally, there are two selfie cameras: a 32MP internal camera that can record up to 4K video and a 20MP external selfie cam, both with a f/2.4 lens.
