1. Outdoor Sports
1) Where are the anti-counterfeiting marks usually placed on sneakers?
A: They are usually placed on the shoe tongues. For anti-counterfeiting information of sneakers, special attention should be paid to the shoe tongues.
2) Where is the primary identification information of sports apparel located?
A: It is located in the tag. The tag’s material, font, and the information printed on the tag are some of the key information for determining whether the product is authentic or not.
3) What kind of issues can be used to identify counterfeit sneakers?
A: If the sneakers have a pungent smell of lacquer thinner, they might be fake, as counterfeit sneakers use inferior glue that may give out a pungent smell.
4) Where is the most prominent trademark usually printed on sneakers?
A: It is usually printed on either side of the sneakers. Trademarks of sneakers are normally printed on the upper of the sneakers, not on the sole.
5) What are the main measures to protect the intellectual property rights of sportswear brands?
A: Trademark and copyright, e.g. New Balance is a protected trademark and the official promotional images of a particular brand are protected by copyright.
6) When one copies the design and color scheme of other’s product, what intellectual property right might be infringed?
A: Design patent. The design patent is the patent rights granted to a design in accordance with the law, including the shape of the product, the pattern of the product, the shape and pattern of the product, the shape and color of the product, the pattern and color of the product, the shape, pattern, and color of the product.
7) What is the life span of a pair of sneakers?
A: 6 months. The life span of a pair of sneakers is usually 6 months or 400 kilometers. Once the life span is exceeded, the protection and shock absorption provided by the sneakers for the feet and torso might be weakened substantially.
8) Which part of the sneakers is the most technology-intensive?
A: The shoe soles. With the constant progress of science and technology, the technology used in modern sneakers has been advancing as well. For example, effective shock absorption performance can improve the comfort level of the sneakers, buffering the shock caused to the body by the impact forces during exercise, protecting the human bones and joints. The shock absorption performance of the shoes primarily depends on the material and structure of the soles.
9) What is the weight of a standard size 7 basketball?
A: 600-650 grams. Size 7 basketball is the standard basketball size in men’s game, with a weight of 600-650 grams, a circumference of 75-76 centimeters, and a diameter of 24.6 centimeters.
10) John bought a basketball and sliced it open, only to find that it has an inner bladder and a surface only. What can we tell from this?
A: It is a basketball of inferior quality. Every Spalding basketball consists of four parts: the surface, the inner bladder, the middle bladder, and layers of fiber. In the production of many inferior basketballs, some materials are omitted in order to cut costs, making them very dangerous to use.
11) John bought two basketballs of different models, yet the anti-counterfeiting code is identical. What should he do?
A: He should perform anti-counterfeiting verification as soon as possible. In general, every basketball has its own unique anti-counterfeiting code. If two basketballs have the identical code, the buyer should carry out anti-counterfeiting verification to play it safe.
2. Toys
1) What are the capabilities that can be developed by playing with building blocks?
A: Playing with building blocks can help develop children’s hand-eye coordination, color cognition, spatial imagination, and hands-on ability, etc.
2) What kind of building blocks toys should we choose for 0 to 2-year-old infants?
A: We should choose the building blocks in bright colors and big sizes.
3. Beauty and Skincare
1) John wants to produce and operate facial cleansing devices. He is planning to copy the designs of other brands. Is he doing the right thing?
A: No. He should conduct independent R&D and come up with his own design. Imitating or copying other brands may be potentially infringing their intellectual property rights. He may need to bear relevant legal responsibilities, and may even be deemed to have committed an offense.
2) What are the risks of purchasing counterfeit facial cleansing devices?
A: The safety of consumers may be at risk. Counterfeit facial cleansing devices are usually made of poor quality materials, which may easily damage your skin. Most counterfeit products are poorly waterproof, thereby incurring potential safety risks from electricity leakage.
3) What type of silicone facial cleansing devices should be John’s first pick?
A: He should choose products made by licensed manufacturers. As the fiber bristles of the silicone brush will directly touch your skin, you should purchase safe facial cleansing brushes that can cleanse your skin softly and gently. If you notice distinct silicone odors and firm fiber bristles, you may have purchased a counterfeit product.
4) John affixed another manufacturer’s registered trademark on his facial cleansing devices without due authorization. What rights did he infringe?
A: He infringed trademark rights. Registered trademarks are legally protected. Any unauthorized use of a registered trademark on the same or similar products or services may constitute trademark infringement.
5) Respiratory Protection Against Viruses: Common Information About Face Masks
Q1: What kind of particulate-filtering face masks (or disposable face masks) can protect us from viruses?
The World Health Organization (WHO) and China’s medical agencies recommend the use of NIOSH-approved N95, European FFP2, or respirators in equivalent protection level for medical staff who may be exposed to viruses for respiratory protection in certain circumstances. N95 face masks are certified by the US National Institute for Occupational Safety and Health (NIOSH), which can provide the same level of protection as medical protective masks meeting the Chinese standard, KN95 face masks, and FFP2 protective masks meeting the European standard. It should also be noted that viruses may be transmitted between people through saliva and mucosae. Hand hygiene is also important.
Q2: How can particulate-filtering face masks filter viruses?
Particulate-filtering face masks are designed to reduce individual exposure to suspended particles in the air. Pathogenic microorganisms, including pathogenic bacteria or viruses, are particles that can be filtered by anti-particulate materials. The filtration efficiency of microorganisms is equivalent to that of non-microbial particles (such as dust, smoke, and fog) with the same physical characteristics, including sizes and shapes. However, compared with most of the particulate pollutants in the industrial environment, anti-particulate face masks have no exposure limit, i.e. the permissible safety level, to pathogenic microorganisms. Therefore, although respirators can reduce an individual’s exposure to pathogenic microorganisms in the air, they cannot thoroughly protect wearers from being exposed to them. Consequently, wearers may still get infected and ill through other means if they do not take precautions on hand hygiene or protect the eye mucosa or take other measures.
Q3: What are the differences between the certification classes of N95, KN95, and FFP2 masks?
N95 is the American respirator certification class, certified by the National Institute for Occupational Safety and Health (NIOSH). N95-certified respirators have a filtration efficiency of at least 95% against non-oily particles and must be labeled with the wordings “NIOSH” and “N95”;
KN95 is a respirator certification class that meets China’s mandatory standard GB2626-2006. KN95-certified respirators have a filtration efficiency of at least 95% against non-oily particles and must be labeled with the wordings “GB2626-2006 KN95”;
FFP2 is a CE certification class for respirators that meet the European EN149 standard.FFP2-certified respirators have a filtration efficiency of at least 94% against oily particles and non-oily particles and must be labeled with the wordings “EN 149:2001+A1:2009 FFP2”.
All these respirators (protective masks) need to be designed to fit tightly to the face so that the air only travels through the filter material of the mask instead of leaking in from around the edges of the mask. All certified masks are produced within the prescribed quality standard system.
Q4: Is it a must to use medical protective masks for protection against viruses? What is the difference between medical N95 and N95 protective masks?
Medical protective masks are government-approved protective masks designed to protect medical workers in a specific medical environment. Both medical protective masks and ordinary N95 protective masks can offer respiratory protection against particles suspended in the air. However, there are additional requirements for protective masks used in medical environments. On the one hand, to protect patients from being infected by medical workers during surgery or treatment, the medical masks worn by the workers must be able to block the droplets and bacteria produced from breathing and talking from entering the operating environment. Moreover, masks must also be hygienic, meaning that the original number of microorganisms on the masks should not exceed the standard, and no exhalation valve is allowed on masks.
On the other hand, to protect medical staff from being infected by high-pressure streams of infectious body fluids generated during surgery or treatment, which may be splattered on masks and subsequently infiltrate and contact the wearer’s mouth and nose, medical masks must be able to resist the penetration of high-pressure streams of blood and body fluids. These two requirements are indeed the major requirements for medical surgical masks. Medical protective masks must have the functions of ordinary N95 protective masks and medical surgical masks at the same time.
Meanwhile, ordinary N95 protective masks do not need to fulfill the requirements for penetration resistance of blood and body fluid and microorganisms control, unlike medical surgical masks and medical protective masks possess. Therefore, it is a misunderstanding that only medical protective masks can prevent the contraction of bacteria and viruses. These masks are used to protect medical workers from splatters of high-pressure body fluid streams. In other situations, ordinary N95 protective masks or protective masks with equivalent performance will do.
Q5: Can protective masks with exhalation valves be used to prevent viral infection?
Exhalation valves are designed to reduce the exhalation resistance of protective masks. Medical protective masks are not allowed to have exhalation valves because the opened exhalation valves may expel the droplets or bacteria discharged by the mask wearer out of the mask, which may pose risks to the patients undergoing surgery.
Hence, if you wear a protective mask to help prevent viral infection, it is perfectly fine to select a more comfortable protective mask with an exhalation valve. However, if you suspect that you have been infected by a certain virus, you should take the initiative to wear a mask to protect others, which should not come with an exhalation valve; otherwise, it will not serve the purpose of protecting others.
Q6: How long can disposable protective masks be used?
A mask needs to be replaced when it is soiled or damaged, or when breathing is difficult caused by increased resistance, etc.Factors affecting the service life of masks include nose clips damages, loosened ear loops, masks deformation, odorous or dirty masks, and increased breathing resistance, etc. Masks should be changed in time whenever any such situation occurs.
As viruses and other pathogenic microorganisms are contagious, there may be some infectious substances on the used protective masks. If you touch the contaminated surface of a used mask with your hands, you may bring the pathogenic microorganisms to other places (door handles, for example), or you may get infected by touching your mouth and nose with your contaminated hands. Therefore, be sure to clean your hands before and after putting on a mask.
If you plan to reuse the mask, store it in a clean and dry place, and keep it away from any place that may be contaminated. Particulate protective masks (sometimes also called disposable masks) cannot be reused after cleaning or disinfection. Therefore, the safest way is to properly dispose the masks that have been in contact with infectious substances after a single use.
Q7: Can protective masks be washed? Can they be disinfected?
3M particulate protective masks (a.k.a disposable masks) cannot be reused after cleaning and disinfection, because the cleaning and disinfection process often reduces the filtration efficiency, deforms the masks, or wears down the ear loops. Sometimes, there would be disinfectant residues that pose a threat to the wearer.
Replaceable respirator masks make use of airtight rubber or plastic mask body that comes with replaceable filter elements. This type of mask can be cleaned or disinfected as per the product usage instructions, but you should not clean the filter element.
Q8: Is there a difference between masks used by children and those used by adults?
Yes, children are not recommended to use adult masks. To help ensure protection efficacy, protective masks must fit well and tight to the wearer’s face. Protective masks for adults are not specifically designed and produced to be used by children, and no evaluation has been done as to whether they can be used by children. If a child has a smaller face, or his/her face shape does not match a mask, the mask may not be able to be fully fitted to the face, causing particles such as viruses and haze
to leak in from the edges of the mask, thereby failing to ensure its protective effect.
3M particulate respirators for children (suitable for 7-12 years old) and particulate respirators for teens (suitable for 12 years old and above) have all passed the GB2626-2006 KN95 testing requirements: the filtration efficiency for non-oily particles is ≥95%. At the same time, children/teenagers have been invited to undergo actual fitting tests, and it is easier to achieve an effective fit with real faces. 3M particulate protective masks for children and teens can be recommended to help prevent viral infection. Meanwhile, we have taken into consideration the special application needs of special groups such as children or minors and employed the existing technology in the process of product design, applicability evaluation, and user guide.
Parents should adequately recognize some risks when choosing protective masks for their children. These risks include but not limited to, 1. Many children may not be able to master the correct way of using respiratory protective equipment; 2. Some children may not be able to stop wearing by themselves when they feel unwell; 3. Protective masks have some performance features, requiring the wearers to read and correctly understand all instructions before using them, and to wear them correctly with the help of parents.
Q9: Are masks that claim to kill bacteria more protective?
No. There are two main factors to determine the respiratory protection effect of a mask against pathogenic microorganisms in the air. The first is its filtration efficiency against particles, and the second is the fitness between the mask and the wearer’s face.
Although some products claim that the mask material will kill the bacteria on the mask (this depends on the reliability of the evaluation method), this sterilization effect is ineffective for bacteria that leak through the mask and the seal, so it does not improve the overall respiratory protection effect.
Q10: Are sterilized protective masks more protective?
No. Sterilized masks mean that there are no bacteria on the new unopened masks. However, humans are bacteria carriers. There are bacteria on our skin and nasal and oral cavities. The mask will be contaminated with bacteria once it is worn on the face. Therefore, sterilized masks only mean that they are clean on their own, and do not mean that their protective features have been improved. Hence, according to China’s medical mask product standards, product sterilization is not required as long as certain pathogenic
bacteria are not found on the masks, and the total number of bacterial and fungal colonies do not exceed the standard.
4. Small home appliances
1) A shop claims to sell low-priced used refurbished goods. Should John buy it?
A: Buy with caution.
2) What should be paid attention to when purchasing cross-border electrical products?
A: Technical adaptability.
5. Vehicles & Accessories
Which of the following problems may be caused by using counterfeit oil filters?
A: It is difficult to achieve the filtering effect required by the car engine with an inferior filter made from poor quality paper. Moreover, the oil filter with a filtering area smaller than the original spare parts has poor filtering efficiency and cannot effectively filter out harmful impurities from the engine, which will cause premature engine wear. Furthermore, inferior engine filters often do not have a bypass valve, and the engine will not be able to obtain sufficient oil lubrication once the filter is blocked. In severe cases, it can cause the engine to will slip gears, burn, or even scrap.
6. Consumer Electronics
1) Talking about camera batteries, what are the risks of buying fake batteries? How to identify genuine and fake batteries
A: A fake camera batteries may have a shortened life, or in severe cases, it can cause spontaneous combustion and explosion. We will teach you how to tell counterfeit camera battery using Canon as an example. a. Examine the external packaging of the camera carefully. Opening the external packaging is the first step for us to see the camera battery, and it is also the “first test” in recognizing counterfeit products.
Generally speaking, genuine batteries will come with complete external packaging. Counterfeit products, however, will not. Most of them come with lousy packaging; some of them even come without packaging.
Hence, when you see such a battery, it is most likely a fake product. Quickly report and return it!
B. Laser anti-counterfeiting labels provide a good guarantee! Canon adopts a uniquely-designed laser anti-counterfeiting label on the external packaging of the camera battery, the genuineness of which can be examined by the naked eye.
It is a real act of kindness for all consumers.
In addition, some models of Canon camera batteries have laser security labels on the side of the batteries.
Such as the NB-12L\\NB-13L\\LP-E17 batteries:
The genuineness of products is guaranteed with the anti-counterfeiting labels.
The ultimate solution to avoid being cheated naturally is to go to the brand’s official store or official authorized store.
