　　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.So, car camera manufacturer On the contrary, there is still a lot of room to play. 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.

　　led screen quality

　　Common Misconception

　　Many people believe that the lifespan of LEDs and ICs, which can reach up to 100,000 hours, guarantees a screen¨s durability if it operates 24/7. However, this is a necessary but not sufficient condition. The proper use of red, green, and blue lamps, along with the optimal adjustment of ICs, plays a vital role in achieving a high-quality display. Just as a high-end engine doesn¨t guarantee a top-performing car, the key lies in how well all components work together.

　　Temperature Sensitivity

　　LEDs and ICs, being semiconductor devices, function best at around 25≧. However, in outdoor environments, temperatures can vary drastically, from over 60≧ in summer to below -20≧ in winter. Manufacturers often test products at 25≧, but real-world conditions can cause significant performance variations. For instance, at high temperatures, the brightness of LED lights may decrease unevenly, leading to a distorted or “flowery” display. Similarly, if the temperature in the cabinet exceeds 85≧, the IC may become unstable, further affecting the screen’s quality.

　　Power Supply Considerations

　　The power supply is another critical factor. Its stability, output voltage, and load capacity can vary under different temperatures, directly influencing the screen¨s performance. A reliable power supply ensures consistent operation and supports the screen¨s overall quality.

　　Cabinet Design

　　The design of the cabinet is equally important. It not only provides circuit protection and safety but also affects ventilation and heat dissipation. As the screen operates, thermal drift can degrade image quality over time, making effective heat management essential.

　　Environmental Impact

　　Outdoor LED screens face additional challenges, such as temperature fluctuations, UV radiation, and humidity. Over time, these factors can cause deformation in materials like ABS masks, iron boxes, and connectors, leading to issues such as light blockages, unreliable solder joints, and signal interruptions. The result is often a screen that fails to maintain its original quality and consistency.

　　In daily life, we often use plastic PE gloves. Plastic gloves are disposable items that are easily consumed in daily life. We use a pair for stewed food, a pair for crayfish, and a pair for home hygiene. While plastic gloves provide us with convenience, they also cause a certain degree of environmental pollution due to excessive use and lack of recycling, becoming “white garbage”. As environmental protection becomes more and more important, we need to enhance our environmental awareness and pay attention to this matter.Therefore, this is the choice biodegradable mailing bags The reason, there is no denying its positive impact. https://biodegradable-gd.com

　　Biodegradable PLA gloves are disposable gloves made from polylactic acid (PLA), a biodegradable and bioactive thermoplastic derived from renewable resources like corn starch or sugarcane. Unlike traditional disposable gloves made from synthetic materials such as nitrile or latex, PLA gloves are designed to break down more quickly and sustainably in the environment. Here¨s a detailed look at compostable PLA gloves:

　　Benefits of biodegradable gloves:

　　1. The performance remains unchanged during the shelf life, and after use, it can be degraded into inorganic substances such as carbon dioxide and water under natural environmental conditions, becoming nutrients for plants and will not pollute the environment

　　2. Easy to use, not only green and healthy, but also very convenient to use

　　3. The raw material source of biodegradable gloves is very environmentally friendly. The raw material comes from polylactic acid PLA, which comes from plant resources such as corn and potatoes. It is green, environmentally friendly and sustainable. It will not come from petroleum like plastic PE gloves, which is not sustainable, and the production process is very polluting.

　　When purchasing compostable gloves, we need to try to choose large platforms for purchase. When purchasing, you need to confirm the ingredients of the biodegradable gloves with the merchant, which are generally polylactic acid PLA, polyadipate PBAT, and starch. Others such as PE+starch are pseudo-degradable gloves, not qualified degradable gloves, and need to be purchased with caution.

　　Biodegradable PLA gloves are a promising alternative to traditional disposable gloves, offering significant environmental benefits through the use of renewable resources and compostable materials. As technology and manufacturing processes advance, the performance and accessibility of compostable PLA gloves are likely to improve, making them a viable option for a broader range of applications.

　　Recently, market research firm LightCounting (hereinafter referred to as LC) released a new report on the theme of “Optics for Artificial Intelligence”. The report points out that artificial intelligence has emerged in the blink of an eye. LC’s first “Optics for Artificial Intelligence” report emphasizes how artificial intelligence is changing computer architecture and networks, and optics plays a key role in this. LC’s artificial intelligence predictions focus on optics. However, the agency said that if there is one more prediction, it is: not only will optics play an important role in the development of artificial intelligence systems, but artificial intelligence will increasingly contribute to the design of these systems at the transistor, chip and system levels.In addition to these aspects, 400g qsfp-dd The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://www.3coptics.com/

　　optical technology

　　The pace of innovation varies across industries. New applications are developed at a rapid pace. Most of them will fail, but some will succeed and seemingly change the world overnight. Software and AI algorithms are being innovated faster than we can imagine. At least that¨s what it seems to be to outside observers, but experts may not see it that way.

　　Innovation in the hardware space is a more gradual but relentless process. Optical connectivity is no exception, and there is solid data to support this. The adoption of silicon photonics has taken a decade, waiting for the technology to bring truly disruptive solutions, such as reliable co-packaged optics. This will undoubtedly happen by the end of this decade, but the forecasts in this report focus on pluggable optical modules deployed in AI clusters – the dominant solution for optical connectivity today and over the next five years.

　　Currently, more than 90% of optical modules deployed in AI clusters are used for InfiniBand and Ethernet connections. As shown in the figure below, the bandwidth required for NVLink to connect to GPUs is 4 times that of Ethernet and InfiniBand. Another bottleneck in AI cluster design is the limited high-bandwidth memory (HBM) available to GPUs, which is another factor in the 3x bandwidth increase.

　　optical technology

　　It turns out that optical switches can be used to scale and reconfigure its AI clusters to improve cluster performance while minimizing cost and power consumption. The research firm expects more companies to adopt this technology in the next 3-5 years.

　　The scale of optical demand for applications in AI clusters is a pleasant surprise in 2023, and the timing of ChatGTP making headlines in late 2022 is particularly significant. Fears of an impending recession and initial signs of declining revenue growth have forced all leading cloud companies to cut spending, including investments in data centers and purchases of optical modules. Strong growth in 2024-2025 is unquestionable.

　　The growth of business from large network equipment manufacturers is the main factor affecting the sales volume of optical modules in 2023-2025. New designs for AI clusters require more optical modules. All previous systems used only InfiniBand networks for optical connections, and most of these systems were AOCs. The latest systems based on NDR (400G) InfiniBand use pluggable 400/800G SR4/SR8 and DR4/DR8 optical modules instead of AOCs. The company also released an NVLink chassis switch designed for 800G optical connections in March 2022. The company is currently testing optical fiber NVLink internally, but these solutions should be available to end users by the end of 2024. If it takes longer, LC said it will have to lower its forecast for 2025-2029.
