How do security X-ray machines distinguish between explosives, drugs, guns, knives and other dangerou

  As the economy develops more and more, people’s living standards improve and their requirements for security are getting higher and higher. At the same time, due to factors such as wars in the third world, terrorists and extremists, domestic airports, railway stations and mass gathering places are equipped with more and more high-end security equipment.Mentioned in the article walk through metal detector Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://secuzoan.com/

  

  The performance of security inspection equipment has improved a lot compared with previous years. Security inspection X-ray machines are essential equipment for security inspection channels. How this equipment can distinguish dangerous items such as explosives, drugs, guns, knives, etc., we need to start with the principle of security inspection machines.

  

  x-ray machines

  The security inspection machine is an electronic device that uses a conveyor belt to send the checked luggage into the X-ray inspection channel to complete the inspection. When the luggage enters the X-ray inspection channel, it will block the package detection sensor, and the detection signal will be sent to the system control part, generating an X-ray trigger signal, triggering the X-ray source to emit an X-ray beam.

  

  The X-ray beam passes through the inspected objects on the conveyor belt, and the X-rays are absorbed by the inspected objects and finally bombard the semiconductor detector installed in the channel. The detector converts the X-rays into signals, and these very weak signals are amplified and sent to the signal processing chassis for further processing. After these signals are processed, they are displayed on the display screen.

  

  ”No matter how many layers a package has, X-rays can penetrate it and display the items in the package layer by layer.” Dangerous items are identified by different colors. Multi-energy colored organic matter is displayed in orange, inorganic matter is displayed in blue, and mixtures are displayed in green. High energy/low energy are switched to display. High energy displays metals, etc., and low energy displays non-metals. In the image display system, the X-ray sensor L-shaped photodiode array detector (multiple energies are optional), 12-bit depth, high penetration display increases the brightness of dark areas in the image, so that items hidden behind highly absorbent objects are clearly displayed. Low penetration display increases the contrast of low absorption (easy to penetrate) objects, making easy to penetrate objects clearer; therefore, the X-ray security inspection machine is not a decoration, but actually undertakes the work of protecting railway safety.

  

  So how does the security inspection machine detect these dangerous items?

  

  1. Image monitoring method

  

  Image monitoring method directly determines the object from the X-ray image configuration. Therefore, whether the object is suspicious depends on the image on the monitor or display. Unusual objects or objects with different shapes that appear on the display or monitor should be considered suspicious objects. Objects that cannot be accurately identified should also be considered suspicious objects and need to be carefully investigated. The image can be located and analyzed as needed.

  

  2. Color analysis method

  

  The color analysis method is to identify the type of material based on the different colors that different materials show under the x-ray image. The various colors that appear on the monitor are a reflection of the density, quality and quantity of the object. Therefore, the quality of the object can be evaluated based on the depth of the image color.

  

  Light yellow is generally the color of a single piece of clothing, thin plastic, and a small amount of paper.

  

  Orange is generally the color of soap, soap, explosives, drugs, wood, leather products, etc.

  

  Dark orange is generally the color of a large number of books, paper, RMB, high-concentration liquids, large bags of rice and flour, etc.

  

  Blue is the color of inorganic substances such as copper, iron, and zinc. Thick cables, stun guns, bullets, gun barrels, guns, and knives show different shades of blue. Green is the color of mixtures, stainless steel products, cables, etc. show different shades of green. Red is the color of impenetrable objects, mostly heavy metals and thick objects.

In-depth analysis Which is better, a memory foam pillow or a latex pillow

  It is not possible to generalize between memory foam pillows and latex pillows. It depends on personal pillow needs. First of all, let us understand the essential difference between them. As the name implies, their essential difference is the material. In terms of touch, latex material will be softer than memory foam. If it is a real natural latex or a latex pillow with a high content, although it is soft, its support is also very good. Secondly, in terms of the effectiveness of the pillow, the memory foam material has the characteristic of automatic temperature adaptation at 37 degrees. When the human body contacts the pillow, the pillow will automatically fit the cervical spine, perfectly fitting the physiological curvature of the cervical spine. Therefore, if you are purchasing for the purpose of cervical health care or cervical repair, then the memory foam pillow is obviously better than the latex pillow.So, I believe travel pillow memory foam In the future, it will be promising to create a miracle belonging to the industry. https://tainengjikang.com/

  

  In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

  

  We can choose whether to buy a memory foam pillow or a latex pillow based on our personal needs and the following situations.

  

  In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

  

  1. Latex is a relatively environmentally friendly material. The premise of this environmental protection is natural latex. The pillow made of real pure natural latex has excellent antibacterial and anti-mite effects, which is very suitable for infants and young children who have high requirements for anti-mite and anti-bacterial. In addition, latex feels very soft, but still has a certain degree of support, which is suitable for people who like to sleep on soft pillows.

  

  2. The main function of memory foam is to absorb the pressure of the cervical spine and relieve the cervical spine. If used consistently, it can maintain the physiological curvature of the cervical spine at 12\5. Due to its professionalism in cervical spine repair, memory foam is very suitable for people with sub-healthy cervical spine or cervical spine lesions. Using it all night can help users repair the cervical spine during sleep and effectively relieve the discomfort of the cervical spine caused by strain.

  

  3. In terms of smell, newly produced memory foam has a slight smell, but this smell is harmless to the human body. Generally, the smell of memory foam pillows disappears in about 3-5 days. The real natural latex pillow has a very strong latex smell, which generally fades in 3 to 6 months, but there will always be a faint latex smell that will not disappear. Therefore, if you are very sensitive to smell, it is recommended to choose a memory foam pillow.

  

  4. In terms of service life, latex material has a natural fatal weakness, that is, it ages very quickly. During use, latex material will oxidize with air, and after oxidation, it is easy to shed small dandruff on the surface and produce odor, and the pillow will become hard, which will not provide any support for the cervical spine. Although under normal circumstances, it is recommended to replace the pillow every 2 to 3 years to prevent bacterial growth, if the pillow has begun to age before it is replaced, it will not have any positive effect on the cervical spine.

  

  In-depth analysis: Which is better, a memory foam pillow or a latex pillow?

  If it is used daily to protect the vertebrae and relieve the cervical spine, it is recommended to choose memory foam or latex material. Of course, if the focus is on the neck protection function, memory foam is definitely more preferred. The most intuitive difference between these two materials is that the real memory foam material feels harder than real latex or latex pillows with a high latex content. The real natural latex material or latex pillow with a high latex content feels quite soft, but both have very good support. Of course, this premise is that you buy high-quality products. If it is a memory foam with talcum powder added, or a latex pillow made of synthetic latex, its effect and comfort level will be greatly reduced.

How to Effectively Use PIR Motion Sensors in Outdoor Environments

  In today’s technologically advanced world, PIR (Passive Infrared) motion sensors have become a cornerstone for enhancing security and automation. Their versatility allows them to be used in various settings, but one of their most critical applications is in outdoor environments. Effectively utilizing PIR motion sensors outdoors can significantly boost security, energy efficiency, and convenience. Here¨s how to harness the full potential of these devices.Mentioned in the article motion detector sensor Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://www.sunlit-tech.com

  

  PIR motion sensors work by detecting changes in infrared radiation within their field of view. This makes them ideal for outdoor environments where detecting movement or changes in heat patterns can be crucial. These sensors, often referred to as PIR detectors, are designed to identify the heat emitted by moving objects, such as people or animals, which makes them highly effective in surveillance and security systems.When installing PIR motion sensors outdoors, the key is to understand their operating principles and optimize their placement. Unlike indoor environments, outdoor spaces can present challenges such as varying temperatures, weather conditions, and potential obstructions. To maximize the effectiveness of your motion detector sensors, it¨s essential to consider these factors carefully.

  

  

  First and foremost, the placement of PIR motion sensors is crucial. Positioning them at strategic locations can help cover larger areas and ensure comprehensive monitoring.
