Hitachi Kokusai’s Surveillance Camera can Recognize One From 36 Million in Seconds

Japanese Company Hitachi Kokusai Electric recently revealed its new Surveillance Camera Hitachi Kokusai which have demonstrated the use of its new security watch camera in the video that you can see here below. This surveillance system can actually search 36 million faces through database in one second, this system can automatically detect face taken from a regular photo and the search results can be displayed immediately on the live monitoring system provided. When a man is selected you can see persons live actions followed by a rectangular highlight on him in the watch window. Kokusai Electric thought that this system is suitable for customers that relatively have a large scale business and need a large scale surveillance for example the railways, law enforcement offices, large stores and power companies. They plan to release this security camera in the next financial year and each of the project will be handle individually. If you find this interesting you can contact Hitachi Kokusai for the price and further details for this security system.

Rise of the Machines in America's Military... sand fleas & roaches are the new Soldiers!

 RHex is a six-legged, 30-pound crawling bot inspired by cockroaches. It squirms around through mud, streams, and rocky terrain, going up to six hours on a battery charge. Boston Dynamics, who are the creators of the very awesome BigDog and a menagerie of other bots, is sending two small reconnaissance robots to the U.S. Army for testing.
                                                                                   Sand Flea and RHex, developed from the funding from the Army's Rapid Equipping Force, are off to the Army Test and Evaluation Command to pass safety and reliability assessments.Three RHex units have already been delivered to ATEC and Sand Fleas will join them later this year, Boston Dynamics said in a release. The machines could improve soldiers' awareness of threats in war.

Laser-Guided Bullet

Sandia National Laboratories engineers, have developed a patented design for a laser-guided bullet. The 4″-long laser-guided projectile has made hits at ranges up to 2000 meters. No this is NOT an April Fools’ joke. The projectile shoots from a smooth-bore rifle and uses small, movable fins to adjust its trajectory. The fins are controlled by micro-sized actuators in response to signals from a tiny, onboard laser-sensor. Plastic sabots provide a gas seal and protect the delicate fins while the projectile is in the firearm’s barrel.

The researchers Red Jones and Brian Kast (and colleagues) have invented a dart-like, self-guided bullet for small-caliber, smooth-bore firearms that could hit laser-designated targets at distances of more than a mile. “We have a very promising technology to guide small projectiles that could be fully developed inexpensively and rapidly,” Jones said. Researchers have had initial success testing the design in computer simulations and in field tests of prototypes, built from commercially available parts, Jones said. While engineering issues remain, “we’re confident in our science base and we’re confident the engineering-technology base is there to solve the problems,” he told.

The design for the four-inch-long bullet includes an optical sensor in the nose to detect a laser beam on a target. The sensor sends information to guidance and control electronics that use an algorithm in an eight-bit central processing unit to command electromagnetic actuators. Theseactuators steer tiny fins that guide the bullet to the target.

Fin-Stabilization — Like on a Guided Missile
The guided projectile is shot from smooth bore barrel with no rifling. While conventional bullets are spin-stabilized, Scandia’s guided bullet doesn’t spin in flight. To enable the guided bullet to adjust its trajectory toward a target and to simplify the design, the spin had to go, Jones said. As on most guided missiles, fins both stabilize and steer the projectile. But on this projectile, the fins are tiny — just a few millimeters tall.

The bullet flies straight due to its aerodynamically stable design, which consists of a center of gravity that sits forward in the projectile and tiny fins that enable it to fly without spin, just as a dart does, he said. The four-inch-long bullet has actuators that steer tiny fins that guide it to its target.

Projectile Flies at 2400 fps — More Speed Is Possible
Testing has shown the electromagnetic actuator performs well and the bullet can reach speeds of 2,400 feet per second, or Mach 2.1, using commercially available gunpowder. The researchers are confident it could reach standard military speeds using customized gunpowder.

Sub-MOA Accuracy at 1000m — No Matter What the Wind Does
Computer aerodynamic modeling shows the design would result in dramatic improvements in accuracy, Jones said. Computer simulations showed an unguided bullet under real-world conditions could miss a target more than a half mile away (1,000 meters away) by 9.8 yards (9 meters), but a guided bullet would get within 8 inches (0.2 meters), according to the patent.

The prototype does not require a device found in guided missiles called an inertial measuring unit, which would have added substantially to its cost. Instead, the researchers found that the bullet’s relatively small size when compared to guided missiles “is helping us all around. It’s kind of a fortuitous thing that none of us saw when we started,” he said.

As the bullet flies through the air, it pitches and yaws at a set rate based on its mass and size. In larger guided missiles, the rate of flight-path corrections is relatively slow, so each correction needs to be very precise because fewer corrections are possible during flight. But “the natural body frequency of this bullet is about 30 hertz, so we can make corrections 30 times per second. That means we can over-correct, so we don’t have to be as precise each time,” he said.

Projectile Becomes More Stable After Launch
Researchers also filmed high-speed video of the bullet radically pitching as it exited the barrel. The bullet pitches less as it flies down range, a phenomenon known to long-range firearms experts as “going to sleep.” Because the bullet’s motions settle the longer it is in flight, accuracy improves at longer ranges, Jones said. “Nobody had ever seen that, but we’ve got high-speed video photography that shows that it’s true".
