In order to catch up with the fashion trend, most people who play basketball now like to wear two silicone bracelets on their wrists, but they don't understand the use of silicone bracelets. The following is a brief introduction to the use of silicone bracelets.
1. In order to facilitate team identification.
When playing basketball, as an unknown player, in order to have some perfect cooperation in the game, such as air relay, etc., they often have to reach out to ask for the ball, and their sign of judging their teammates is the silicone bracelet on their wrists. s color. In the United States, streetball masters often have 4-5 different colored silicone bracelets in their pockets to facilitate team formation.
2. Prevent sweat from flowing on the player's hands and cause the phenomenon of slipping the ball.
Since the silicone bracelet is made of environmentally friendly silicone, it can effectively absorb the sweat discharged from the human body and prevent the sweat from flowing to the player's hands, thereby avoiding the phenomenon of slipping the ball.
3. Fashionable and trendy decorations.
The color of the silicone bracelet is colorful, and you can choose the color and style you like according to your own preferences. After wearing it, matching with your own clothes can play a very good role in decoration and embellishment. It is a must-have for trendy people who catch up with fashion.
4. In order to convey the belief of the wearer.
In today's society, people have more speech rights, and there are many ways to express their thoughts and beliefs. Because the DIY of the silicone bracelet is very flexible, it can completely engrave the LOGO text you want to express on the wrist band according to people's requirements, so as to achieve the role of the wrist band to convey beliefs.
More and more people turn to online shopping this year because of the COVID-19, from small-size items, such as daily grocery, sports tools, to big-size items, such as light products or even furniture. When it comes to light products, most people tend to know whether it’s safety compliant, UL, ETL, or CSA listed, but always ignore FCC certification. So, can I buy a light product without FCC certification from an online store? The answer is yes, and no.
Then, what’s FCC certification? You may already know that FCC is Federal Communications Commission. The FCC office of engineering and technology laboratory division has rules for lighting products to ensure these devices do not cause harmful interference to radio communications services. It’s mandatory for most lighting products. Most lighting products generate not only light but also radiofrequency. For example, LED lights need to transfer high-voltage sinewave alternative current to low-voltage stable direct current to turn on the transistors in LED chips. This electric transformation and distortion will inevitably generate radiofrequency.
Suppose it’s a traditional light fixture, such as an 18-light chandelier with medium screw bases. In that case, FCC certification is not required because the voltage on each lamp socket is the same as line voltage, with no transformation or distortion. But for the bulbs mounted on the traditional light fixture, FCC certification is mandatory, no matter they are incandescent, halogen, CFL, or LED.
LED light must be FCC listed if it is connected directly to line voltage. Some LED lights to adopt FCC certified LED driver, which is good, but not enough if the LED driver is not a detachable part, the whole LED light must be listed as a whole. Take the LED vanity light as an example, the LED driver is mounted inside the backplate with 3M glue and not allowed to unmount by the customer, and then the LED vanity light must be FCC certified.
The LED light doesn't need FCC certification if connected to a low-voltage direct current power source, such as a 12V or 24V LED driver. Take the LED strip light as an example. Its electronic components are pure direct current within the LED strip lights; there is voltage dropdown from the LED driver's outlet, but no transformation or distortion. For sure, the 12V or 24V LED driver must be FCC listed.
For lighting products, UL, ETL, or CSA certification is not mandatory, but products with this certification are much safer than those without. We’d better choose products with UL, ETL, or CSA certification, or at least choose products made of UL, ETL, or CSA listed components.

With the development of the Internet of Things technology, RFID products have entered people's lives, and rfid electronic tags are involved in various fields. RFID tags have different functions at different frequencies, and their application fields are also different.
High-frequency RFID tag is a kind of RFID technology, its working frequency is 13.56 mhz, wavelength is about 22 m.
Usually when passive RFID tags work, the digital exchange must be in the near-field area radiated by the RFID reader antenna. Because it is easy to make into a card shape, high-frequency tags are widely used in electronic ID cards, electronic door lock anti-theft (electronic remote door lock controllers), electronic ticketing, building access control systems, community property management, jewelry inventory management, smart shelf management, Fixed asset management system, library management system, etc.
The working frequency of UHF RFID tags is between 860MHz and 960MHz, which can be matched with different antennas, and can be divided into active RFID tags and passive RFID tags. When working, the RFID radio frequency tag should be in the long-distance area of the UHF reader antenna radiation field, and the coupling method between the RFID tag and the antenna is electromagnetic coupling. The radiated field of the UHF reader antenna provides radio frequency energy to the passive tag and wakes up the passive tag. The reading distance of the corresponding radio frequency identification system is generally more than 1 meter, the typical case is 4 meters long and 6 meters, and the maximum can reach more than 10 meters. The RFID reader antenna is generally a directional antenna, which can only be within the directional beam range of the reader antenna. The corresponding RFID radio frequency identification system has a relatively long reading distance, so it can be used for automatic identification of vehicles, high-frequency identification of vehicles, high-speed identification, high-speed identification, and high-speed identification.
The characteristics of high frequency rfid electronic tag and ultra high frequency rfid electronic tag:
High-frequency tags are cheaper than UHF tags, have strong penetration into non-metallic objects, and their operating frequency is not restricted by radio frequency control. They are suitable for objects with high water content, such as fruits.
UHF tags have high recognition sensitivity, can be read by multiple tags, have a wide range of action, fast data transmission speed, energy consumption, weak penetration, and there should be no too much interference in the work area.
