  How to maintain a memory foam pillow?

  

  1. Pillowcase

  

  Memory pillows usually have outer and inner covers. The inner cover is mostly made of pure cotton fabric, while the outer cover is generally made of velvet fabric. The inner cover can be machine washed or hand washed, and can be dried after being wrung out. It is generally recommended to hand wash the velvet outer cover, and do not wring it too hard when drying. When installing the pillow core, pay attention to the direction of the big and small heads. Most memory pillows are now B-shaped, which cannot be cut open and installed upside down.

  

  2. Pillow Core

  

  (1) Memory pillows are generally made of environmentally friendly polyurethane. This material will turn yellow if left in the sun for a long time, so the pillow core should not be exposed to the sun. Just take it out frequently to ventilate and dry naturally.

  

  (2) Another thing to pay attention to when maintaining the pillow core is that you should not press it with force for a long time. When not in use, leave it in its natural state and do not place it under heavy objects for a long time. This may cause the memory foam to deform, making you uncomfortable when sleeping.

  

  (3) The pillow core cannot be washed. This type of memory foam has a very unique structure. If moisture enters, it will be difficult to clean out, which will also reduce the quality of sleep. Generally, it is used with a pillowcase and an inner cover. If you accidentally sweat, take out the pillow core and let it dry naturally.

  

  Finally, if the newly purchased memory foam pillow has a slight odor, it is normal. Just let it air dry for 3-5 days (if the ventilation is good, the odor can be removed in 2 days), and the odor will be completely gone, and you can use it with confidence.

Analysis of the difference between the flat top and heat sink top of the 400G optical module

  Recently, a sales partner encountered a difficult problem. The optical module received by the customer could not be used. After much research, the reason was found. It turned out that the customer purchased an optical module with a heat sink, which did not match the existing network card slot. What is the difference between the flat top and the heat sink top of the optical module? How to choose when using it? Let’s follow the editor to take a look!So, I believe 400g qsfp-dd In the future, it will be promising to create a miracle belonging to the industry. https://www.3coptics.com/

  

  1. The difference between the flat top and the heat sink top of the optical module

  

  The flat top and heat sink top in the optical module usually refer to two different structures in the optoelectronic device:

  

  Flat-top: Flat-top structure usually refers to the flat top structure of the laser or optical transmitter in the optical module. This design allows light to propagate and focus more easily, which is conducive to more efficient transmission of optical signals in optical fibers or other transmission media. The flat-top design can improve the coupling efficiency and transmission efficiency of light, and is more common in some high-performance optical communications or optical sensors.

  

  Heatsink-top: Heatsink-top structure usually refers to the top design of laser or optoelectronic device with heat sink. These heat sinks are usually used to effectively dissipate heat to keep the device operating temperature within a safe range. In high-power or high-density applications, the device may generate a lot of heat, which needs to be transferred to the surrounding environment through the heat sink to prevent the device from overheating and damage. Therefore, the heat sink design is crucial for the long-term stable operation of the optical module.

  

  400g optical module

  

  2. How to choose the flat top and heat sink top of the optical module

  

  With the increase of transmission rate, the size of the optical module is gradually miniaturized, and the requirements for internal optical devices are getting higher and higher. It is very necessary to solve the heat dissipation problem. The flat top and heat sink top of the optical module each have their advantages. Which one is better depends mainly on the transmission rate, interface type, packaging method and specific application scenarios and requirements.

  

  Transmission distance and rate requirements: If your application requires long-distance high-speed transmission, the flat-top structure may be more suitable because it is conducive to improving the coupling efficiency and transmission efficiency of light. For short-distance or low-speed transmission, the heat sink top structure can be considered more.

  

  Thermal management requirements: If the laser or optoelectronic device in your application needs to handle a lot of power or high-density energy, the heat sink top structure may be more important because it is conducive to effective heat dissipation, thereby maintaining the stable operation of the module and preventing overheating from causing performance degradation or damage. Especially in applications such as high-power optical communications or lidar, good thermal management is essential.

  

  Cost and complexity: The flat-top version of the optical module has a simple design and no additional heat sink structure, because it focuses on the light transmission efficiency, while the heat sink top structure may require a more complex design and manufacturing process to ensure good heat dissipation performance. Therefore, you need to weigh these two options when considering cost and complexity.

  

  Environmental conditions: Consider the environmental conditions in which your application will operate. If the ambient temperature is high or there may be other heat sources, good heat dissipation may be more important.

  

  Reliability and stability requirements: If your application has high requirements for long-term stable operation of the device, it may be more appropriate to choose a heat sink top structure that can provide good thermal management.

What is the relationship between ADAS and automotive functional safety

  Functional safety solves the problem of failure of electronic and electrical systems, such as a camera suddenly breaking down or a domain controller system failure. Traditional ADAS systems will fully consider functional safety during the system design stage. At present, this field is the most mature compared to other safety areas, and is also supported by international standards ISO26262 and some regulations.For the immediate pressure, car camera manufacturer With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://szdfpls.com

  

  Expected functional safety solves the problems of insufficient related functions, performance limitations, and human misuse after the complexity of system functions increases. For example, if the driver does not operate the intelligent driving function correctly, the perception algorithm function is limited and cannot accurately identify the faded lane line, or the perception identifies the truck in front as blue daytime, this will bring fatal problems.

  

  At present, the ADAS system has not yet achieved a good implementation combination with expected functional safety, but according to my observation, some companies are also paying attention to this aspect and starting to make some expected functional safety supervision mechanisms. Expected functional safety is more targeted at high-level ADAS systems (L3 and above), because the system is more complex and needs to pay more attention to expected functional safety.

  

  Information security, this direction involves more and wider areas than the first two, involving data communication security between vehicles and within the vehicle. At present, I personally have not been exposed to information security in ADAS, and I hope that other experts in information security can talk about it together.

How to maintain a memory foam pillow

  Every item in life needs careful maintenance, and your pillow is no exception. Let’s take a look at the maintenance methods of memory foam pillows with Xiao Shi!After that, knee pillow memory foam Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://tainengjikang.com/

The inner cover can be machine washed or hand washed, and can be dried after being wrung out. It is generally recommended to hand wash the velvet outer cover, and do not wring it too hard when drying. When installing the pillow core, pay attention to the direction of the big and small heads. Most memory pillows are now B-shaped, which cannot be cut open and installed upside down.

How to Choose the Surface Treatment Process for Fasteners

  Choosing which surface treatment to use is a problem that every designer faces. There are many types of surface treatments to choose from, and not only should the economy and practicality of the design be considered, but also the processability of the assembly and even environmental protection requirements should be taken into consideration. The following is a brief introduction to some commonly used coatings for fasteners based on the above principles for reference.In order to facilitate users to have a better experience, Non standard hardware factory Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. https://jieruifasteners.com/

  

  1. Electrogalvanizing

  

  Electrogalvanizing is the most commonly used coating for commercial fasteners. It is relatively cheap and looks good. Common colors include black and military green. However, its anti-corrosion performance is average, and its anti-corrosion performance is the lowest among zinc plating (coating) layers. Generally, the neutral salt spray test of electrogalvanizing is within 72 hours. Special sealants are also used to make the neutral salt spray test reach more than 200 hours, but the price is expensive, which is 5 to 8 times that of general galvanizing. The torque-preload consistency of electrogalvanized fasteners is poor and unstable, and is generally not used for connections in important parts. In order to improve the torque-preload consistency, the method of applying lubricating substances after plating can also be used to improve and improve the torque-preload consistency.

  

  2. Phosphating

  

  A basic principle Phosphating is cheaper than galvanizing, but its corrosion resistance is worse than galvanizing. Oil should be applied after phosphating, and its corrosion resistance is greatly related to the performance of the oil applied. For example, after phosphating, applying general anti-rust oil, the neutral salt spray test is only 10 to 20 hours. Applying high-grade anti-rust oil can last for 72 to 96 hours. But its price is 2 to 3 times that of general phosphating oiling.

  

  There are two common types of non-standard fasteners phosphating, zinc phosphating and manganese phosphating. Zinc phosphating has better lubrication performance than manganese phosphating, and manganese phosphating has better corrosion resistance and wear resistance than galvanizing. Its operating temperature can reach 225 degrees to 400 degrees Fahrenheit (107 to 204 degrees Celsius). Especially for the connection of some important parts. Such as the connecting rod bolts and nuts of the engine, cylinder heads, main bearings, flywheel bolts and wheel bolts and nuts. Phosphating high-strength bolts can also avoid hydrogen embrittlement problems, so in the industrial field, bolts above grade 10.9 are generally treated with phosphating surface treatment.

  

  

  3. Oxidation blackening

  

  Blackening + oiling is a very popular coating for industrial fasteners because it is the cheapest and looks good before the oil runs out. Since blackening has almost no anti-rust ability, it will rust quickly after oiling. Even in the presence of oil, the neutral salt spray test can only reach 3 to 5 hours.

  

  4. Electroplating cadmium

  

  Cadmium coating has good corrosion resistance, especially in marine atmospheric environment, its corrosion resistance is better than other surface treatments. The waste liquid treatment cost in the process of electroplating cadmium is high, and its price is about 15~20 times that of electroplating zinc. Therefore, it is not used in general industries and is only used in some specific environments. For example, it is used for non-standard fasteners for oil drilling platforms and HNA aircraft.
