A little guide on skiing jacket

图片
Here's a little   guide on ski jackets . Skiing is an incredibly fun and rewarding activity, but it takes place out in the cold. Nobody likes being cold. Even things that live in the cold, like penguins or polar bears, all hate it. Sure, penguins put on a brave face and often appear happy.... but it's all a charade. So for your own safety and enjoyment, make sure you're wearing suitable outwear before hitting the slopes.   JACKETS These are a couple of factors to consider when looking at jackets. Slightly further down, I'll talk about how these factors are prioritized by the different types of jackets. • Warmth / Material • Waterproofness • Breathability / Venting • Versatility Your jacket selection will depend on the temperature. That's a pretty obvious statement. The jacket you wear skiing in 15 degree weather and the one you wear in 45 degree weather should probably be different. Jackets will have varying degrees of insulation (I'm saying "degree" a

Frequently Asked Questions About Power Splitters/Combiners

图片
  Q. What do the terms “ internal load dissipation ” and “ matched power rating ” mean? A. The matched power rating specifies the maximum power level that can be applied to the input when the output ports are terminated with the specified load resistance. The internal load dissipation refers to the power rating of the internal terminations within the power splitter. A basic lumped element power splitter circuit. This level is given because improperly matched terminations on the output ports can result in reflected signals that could exceed the power limits of the internal terminations. The matched power rating is usually several times higher than the internal load dissipation. Q. Can performance parameters be traded off when specifying power splitter/combiners? A. Once frequency range has been designated, there is not too much leeway in tradeoffs between the various spec parameters. Usually all the performance parameters of a well designed power splitter simultaneously fall off as a fu

DisplayPort vs HDMI: Which one should you use?

  should i use displayport or hdmi ? If you've just bought a new TV or computer monitor, you may be wondering which audio/video cable you should use. While most TVs and computer monitors have at least one  HDMI (High Definition Multimedia Interface) port , some recent models also come with a DisplayPort (DP) connection. The main difference The main difference between DisplayPort and  HDMI  is that HDMI is used to connect most TVs, DVD players, game consoles, and other home theater devices. DisplayPort, on the other hand, is typically found only in computer monitors and some high-end TVs. While each standard has its own advantages, it all depends on the version of each cable you use. Newer versions of HDMI and DisplayPort support higher resolutions and more features. Image quality When it comes to image quality, the DisplayPort vs. HDMI debate comes down to the version of each cable you use. displayPort supports higher resolutions and higher refresh rates without compression. Displa

Why replace the coil spring?

图片
  The function of the Auto Suspension Coil Spring   is to support the vehicle at the desired height, maintain the proper positioning angle and absorb road shocks transmitted through the tires and shock absorbers. Constant flexing in normal service can gradually weaken the suspension system, allowing the car to sag. Once this sag becomes apparent, the entire car suffers. The steering components are forced out of position, thereby changing the geometry of the steering linkage. The loss of the original coil spring can only be fully recovered by installing a new coil spring. This will return the vehicle to the correct height. Most steering linkages systems are designed so that the tie rod assemblies connect to the center link or rack at some angle. On these vehicles, with the steering linkage in front of the spindle, a sagging suspension will force the tie rod out-ward and cause a “toe out” condition . f the linkage is positioned behind the spindle on these vehicles, the outward force of t

Why is liquid silicone optical lens more and more widely used in car headlights?

图片
    With the development of automotive optical products, lens-type headlights have become a major trend. It has not only been widely used in high-end cars, but also gradually promoted to middle and low-end cars. Liquid silicone optical lenses, such as the lens of the human eye. Traditional automotive lenses mostly use glass optical lenses, which have the advantages of high light transmittance, high hardness, and aging resistance. It has unparalleled advantages in automotive applications. However, it also has disadvantages, such as high price, easy to break, difficult to process, etc. Since then, with the development of materials, molds and injection molding technology, PC and PMMA optical lenses have entered the market. Their good processing properties reduce production costs compared to glass. However, the yellowing defect also plagues most automakers. Therefore, the demand for  liquid silicone optical silicone lenses   came into being. The advantages of liquid optical silicone are hi

How Much Do You Know About Model Cars?

图片
  Most people have a very concrete perception of model cars because they can see and touch and play with them, but those who know a little about cars should know that model cars are not as simple as we think, and it is a huge project for  Model Car Manufacturers  to get authorization, determine materials/processes, open molds, produce, preserve and transport. Today, let's take a brief look at the history of model cars. What is a model car? A car model is a scale model made in strict proportion to the shape, structure, color, and even interior parts of a real car. According to incomplete statistics, since the birth of model cars, automobile manufacturers all over the world have launched tens of thousands of models of cars, and broken the monopoly of Europe and the United States in producing and collecting model cars, and gradually developed into a popular collection and investment project in the world. mclaren model car History of model cars The world's first  Model Cars  were b

What is an OLED module

图片
    OLED  display  module  (also called OLED module) is composed of OLED display + PCB + iron frame, which is easy to install and widely used in industrial sites, military and other industries. OLED display refers to organic light-emitting diodes (Organic Light-Emitting Diode, OLED) because of its self-illumination at the same time, no backlight, high contrast, thin thickness, wide viewing angle, fast response, can be used for flexible panels, use temperature It is considered to be the emerging application technology of the next-generation flat-panel display due to its excellent characteristics such as wide range, relatively simple structure and process. Lighting principle: Organic light-emitting display technology consists of a very thin coating of organic material and a glass substrate. These organic materials emit light when an electric charge passes through them. The color of OLED light emission depends on the material of the organic light-emitting layer, so manufacturers can obtai

What Are the Types of Coil Coating?

  In the mid to late 1930s, Joseph Hunter, the founder of Hunter Engineering, installed the first coil painting line. He used this method to paint the shutters as part of a continuous strip. Later, Hunter Engineering went on to design and build more coil coating lines. It was eventually acquired by the Italian global engineering company FATA Spa, which is known for building coating lines all over the world.   Today, the  coil coating process  offers a wide range of opportunities for the world's coating companies. The coil coating process is like one of those giant printing presses that produce evening newspapers. The process does not stop, it runs at a constant speed and the  metal coils  are constantly spliced together so that the moving web can be infinitely long. Aluminum Coil   What is the coil coating process? According to EN-10169:2012-06, the coil coating process is a method of applying a continuous coating of organic coating material to a rolled metal strip substrate. The p
