For $60, a company called Liquipel will take your smartphone, place it in a vacuum and pump a vapor into the chamber. The vapor deposition course of spreads a thin movie over and contained in the device, coating the delicate electronics with a material designed to deflect water — what this materials is made of stays a secret. Another nanocoating maker, P2i, gets slightly more scientific with the reason: “P2i’s patented technology employs a particular pulsed ionized gas (plasma), which is created inside a vacuum chamber, to attach a nanometre-thin polymer layer over your entire floor of a product. When liquids come into contact with it, they type beads and merely run off” [supply: P2i].
Decoy know-how has also superior in response to fashionable detection techniques. The U.S. Army and other navy forces have developed easily-transported, inflatable dummies that not only resemble tanks and different equipment visually, but additionally replicate the thermal or fotografi bayi baru lahir radar signature of that tools. To radar and different lengthy-range scanners, these dummies are nearly indistinguishable from actual tools. A much less precise decoy technique is to flood an space with all types of objects that present up on radar, thermal-imaging and listening devices, making it more durable for the enemy to focus in on any specific piece of gear.
“It is a reasonably unremarkable piece of engineering, however it’s turned into this amazing public space,” Green says. The construction is similar to most overpasses in U.S. freeway construction, and it is not generally somewhere tourists visits for its magnificence, particularly contemplating the historic structure all through London. Nonetheless, the London Bridge affords a wonderful location from which to take pictures of the close by Tower Bridge.
