Computer scientists at Sandia National Laboratories in the US have begun using augmented reality in safety training and analysis.
With the same software as game developers and commercial version of the augmented reality heads, they don't need to start designing from scratch. Tam Le and Todd Noel developed a nuclear facility augmented reality model for the lab's training course.
Le said: "We just use industry-standard tools for game development and apply it to our national security challenges."
The technology shows the spatial relationship of the device in the facility so that students can see the relationship between things. "It helps them understand the vulnerability of the facility, which is difficult to see on paper or in writing," Le said. In addition, students can understand all the processes of handling and protecting nuclear materials without using real hazardous substances.
Le said: "With augmented reality, we can do what we usually can't do. We can display the virtual character processing material, put it into the system, show how the material is taken out, show the next process, let students understand the loopholes And where nuclear material may leak."
Safety training for nuclear facilities has long relied on two-dimensional floor plans, but in recent years it has evolved to use three-dimensional models. Now, AR will take the training to a new level.
Other government agencies have also begun to experiment with virtual and augmented reality. The U.S. General Administration of Administration’s digital government team has created a community to promote the popularity of AR and VR. They plan to hold a hackathon later this year.
FFC connector is a new type of data cable made of PET insulation material and extremely thin tin-plated flat copper wire, which is pressed by high-tech automation equipment production line. It is soft, bending and folding at will, thin in thickness, small in volume, easy to connect, easy to disassemble and easy to solve electromagnetic shielding (EMI).
FPC Flexible Printed Circuit is a form of Circuit produced on a Flexible surface, which may or may not have an overlay (usually used to protect FPC circuits). FPC is more and more widely used because it can bend, fold or repeat motion in a variety of ways and has the advantages of light, thin and flexible compared with ordinary hard board (PCB).
FPC composition materials
1. Insulating film
The insulating film forms the base layer of the circuit, and the adhesive attaches the copper foil to the insulating layer. In a multilayer design, it is then bonded to the inner layer.
They have also been used as a protective cover, in order to make circuit from dust and damp, and the ability to reduce stress during bending, copper foil to form the conductive layer. In some flexible circuits, adopted by the aluminum or stainless steel formed by the rigid member, they can provide the size stability, provides a physical support components and resettlement of the wire, as well as the release of stress.
2, the conductor
Copper foil is suitable for use in flexible circuits, it can use the electric deposition (Electrodeposited, ED.), or plating system.
3. Adhesive
In addition to being used for bonding insulating films to conductive materials, adhesives can also be used as cladding, protective coating, and cladding. The main difference between the two is in the application in which the covering layer is bonded to the covering insulating film in order to form a laminated structure of the circuit.
