What is the fascia of the fascia gun?
What is fascia? How does the fascia gun work?Sun Tingting, the attending physician of the Rehabilitation Department of Fudan Zhongshan Xiamen Hospital, said that fascia is an accessory tissue of muscles. It is a layer of connective tissue that runs through the body and surrounds muscles, muscle groups, blood vessels, and nerves. It is divided into superficial fascia and deep fascia according to the layers. membrane. The deep fascia of the limbs goes deep between the muscle groups and is connected to the bones, playing a buffering role during muscle contraction to avoid friction.The fascia gun uses its internal special high-speed motor to drive the "gun head", which acts on deep muscle and soft tissue through rapid and continuous mechanical vibration, effectively relieving tissue adhesion and over-excitation, and quickly decomposing inflammatory products, thereby promoting metabolism and improving tissue. environmental effects.The earliest fascia gun was used to relax sore muscles after exercise. In NBA live broadcasts, players are often seen using the fascia gun immediately to relax and protect muscles during a break.How effective is the fascia gun?Can it be used to burn fat, lose weight or even cure diseases?The so-called "fascia gun" is not used to treat fascia diseases. Its main function is to relax muscles, promote local blood circulation, and relieve muscle stiffness or muscle fatigue.Patients with fascial injury or chronic fascial pain need to identify the cause and provide symptomatic treatment.● For patients with plantar fasciitis, using a fascia gun to release the calf gastrocnemius and Achilles tendon is more effective than directly impacting the sole of the foot.● For the tightness of the neck and back caused by long-term bad posture or the muscle soreness after exercise and physical activity in healthy people, the fascia gun can be used appropriately to improve the discomfort symptoms.How to use the fascia gun correctly?You should also be careful when using a fascial gun. A man in Wuhan accidentally knocked himself unconscious because of using a fascial gun. Mr. Zhang, a 58-year-old Wuhan citizen, suffers from stiffness and pain in his neck and occasional numbness in his arms due to work reasons. Mr. Zhang's son likes to exercise. After hearing about his father's situation, he also bought an online celebrity weapon for his father-a fascia gun to help him relax his neck and shoulder muscles. But after using it for a few days, Mr. Zhang not only started to feel dizzy, but also experienced nausea and vomiting. Later, he could not even walk steadily. His family quickly sent him to the Neurology Department of Wuhan Fourth Hospital for treatment. During the examination, the doctor discovered that small things called "otoliths" in Mr. Zhang's ears had fallen off! And the culprit is this fascia gun! According to the doctor, the otolith is a physiological existence and a component of the tube balance system. Originally it should wait for the otolith membrane, but after the impact of the fascia gun, it may fall off from the otolith membrane, which will cause a Feeling of dizziness.So how do we use the fascia gun correctly? Generally speaking, the fascia gun needs to be used along the body's muscle texture and fascia direction. It cannot only be used on the sore points of the muscles. It can be massaged at the painful points and the transition points of the muscle belly and tendons. Appropriate pressure can be applied to the massage area. , with a total duration of no more than five minutesHowever, parts such as the head, neck, spine, etc., where a large number of nerves and blood vessels are distributed, cannot be used. Because the muscle tissue in areas rich in nerves and blood vessels is small and fragile, if it is violently shaken, it is easy to aggravate the injury, so everyone should try to avoid stepping on thunder. The intensity of the impact is mainly based on personal comfort. The more painful the better the effect. You need to use a pad when using it. With a soft folded dry towel, start with light pressure and gradually increase the pressure.Have you ever used a fascia gun? How does it feel?Shenzhen Zuchuang Microelectronics Co., Ltd. has been an electronic and electrical solution development, design and chip agency company for 20 years. It is the earliest reading pen solution development company in China and can provide Bluetooth Wifi reading pen OID solution development, smart reading pen solution development, wifi Reading pen project development and other services.

Accelerating IoT Designs with Bluetooth Low Energy Modules
For developers of IoT devices, Bluetooth Low Energy (BLE, also known as Bluetooth Smart) has many advantages. As the name suggests, low power consumption is inherent, and a complete low-power Bluetooth module can basically provide plug-and-play wireless connectivity. Maximizing the benefits of a Bluetooth Low Energy module is to take advantage of the advantages of Bluetooth Low Energy.By now, most developers have at least heard of Bluetooth. This is a wireless protocol that originally appeared in wireless audio streaming applications. The low-power Bluetooth version is shipped with Bluetooth v4.0 and adapts to low-power applications by reducing the transmit power and data speed compared to the core specification (the latest version of Bluetooth is v4.2). Unlike the full core specification, Bluetooth Low Energy has a range limit of 50 meters and a speed limit of 0.27Mbps.Developers new to the Bluetooth Low Energy standard should consider these performance degradations as key points when setting system expectations. Just because the Bluetooth Low Energy protocol is used in a design doesn't mean low power consumption. Designed operational coverage and data speeds play an important role in establishing energy consumption requirements, as does the system's overall communications strategy. Developers need to carefully consider these factors to achieve guaranteed low power consumption.There are many other factors to consider when designing Bluetooth Low Energy IoT devices. The user interface (UI) designed may be related to the same built-in buttons and displays as traditional embedded systems. Or the design can provide the user interface using an app running on a smartphone. Likewise, devices can utilize mobile phones or fixed gateway devices for Internet connectivity.Developers can also choose to pair a Bluetooth low energy device with a host device to establish two-way communication, or work in advertising mode to enable unverified one-way transmission of small amounts of data (approximately 30 bytes). Bluetooth low energy devices (such as sensors) operating in advertising mode can periodically send data to listening devices without consuming energy to establish and maintain a complete two-way link. However, the use of advertising intervals and advertising modes (such as scan requests, which allow listening devices to request additional data from a Bluetooth Low Energy device) can significantly impact the energy consumption values of a Bluetooth Low Energy design.

Energy-saving characteristics and effect evaluation of smart home systems
With the development of science and technology, smart home devices have poured into ordinary people's homes, including smart speakers, smart sockets, smart gateways, smart induction detectors and a large number of smart home appliances. There are more smart programs than traditional devices, so does energy consumption increase compared to traditional home appliances? Today, the editor will introduce in detail the "energy-saving characteristics and energy-saving effect evaluation of smart home systems". 1. Energy-saving characteristics of smart home systemsSmart home devices can control the switches of home appliances and effectively reduce the ineffective standby power consumption time of home appliances. Through intelligent control, the optimization and economical operation of household electrical equipment and the reduction of ineffective energy consumption can be achieved, thereby achieving the purpose of energy saving. Therefore, energy saving is also a natural attribute of smart home systems.Smart home devices add smart features to traditional home appliances. Intelligent functions include timing control, linkage control, logic control, scene control, induction control, adaptive control, environmental monitoring, information identification, information display and transmission, etc. The intelligent characteristics of smart home systems can achieve three goals: functional satisfaction, intelligence, intelligence, comfort satisfaction and energy saving satisfaction.2. Energy-saving effect evaluationFor energy saving evaluation of smart home systems, the power consumption of smart home devices should be considered. That is: smart home system power saving = terminal electrical equipment power saving - smart home equipment power consumption. The energy saving of smart home systems can offset the energy consumption of smart home devices, thereby achieving "zero energy consumption" of smart home control devices.In order to improve the energy-saving effect of smart home systems, the following aspects need to be considered:1. It is necessary to consider the power consumption characteristics of smart home devices and rationally plan energy-saving control solutions. For example, if a smart power outlet is used to control the standby power consumption of a TV, its energy-saving effect is negative. For combined control of household appliances, try to use one smart socket to control multiple household appliances.2. Attention should be paid to the backup power parameters of smart home control equipment, and low-power consumption equipment should be considered.3. Electrical equipment with large backup power should be subject to energy-saving control.

Smart door locks Understand the application of Bluetooth technology in the following popular fields? With the rise of smart homes, the smart door lock market has also been driven. More and more hotels, apartments, school dormitories, residential complexes, villas and hotels are beginning to use smart door locks. Most smart door locks use low-power Bluetooth technology to achieve smart unlocking. The door lock with built-in Bluetooth module can realize remote unlocking by mobile phone, which is simple, convenient and safe.2. With the rise of smart homes, the smart lighting market is also rising. Lamps with built-in lamp control Bluetooth modules can be remotely controlled through mobile applications. As long as you open the LED light control software on your mobile phone, you can control the switch, intensity and color of the LED lights to make your home environment colorful.3. Bluetooth technology for wearable devices has small size, low cost and low power consumption. It is a commonly used wireless communication technology for wearable devices. The Bluetooth module provides a perfect energy-saving and traffic solution for long-term use of small battery-powered wearable devices, enabling wireless transmission and interaction between wearable devices and smartphones.4. In the early days of consumer electronics, the most important application of Bluetooth technology was in the field of consumer electronics. With the continuous development and upgrading of Bluetooth technology, the application of Bluetooth in the field of consumer electronics is becoming more and more mature. More and more electronic products have Bluetooth functions, such as laptops, mobile phones, printers, digital cameras, headsets, keyboards, mice, consumer electronics embedded with Bluetooth modules, and other devices. Communication between them gets rid of the shackles of cables and uses .5. The Bluetooth transmission signal is stable and has the characteristics of wireless transmission. Instruments using Bluetooth modules are not subject to interference from the external environment when monitoring data, and can read and monitor data stably and accurately.6. Intelligent transportation and intelligent parking are effective ways to alleviate the problem of "difficulty parking" in cities. A smart parking space lock solution based on Bluetooth technology can realize functions such as smart parking space locks, usage records, parking space sharing, and parking space search. The parking space lock adopts a Bluetooth module, which can transmit data with the Bluetooth of the control terminal (mobile phone) through a wireless channel, and perform software operation control on the working status of the parking space lock through the control terminal app (mobile phone), effectively utilizing parking space resources and alleviating "parking difficulties". “The problem is in the cities.7. Bluetooth has broad application prospects in automotive electronic equipment. Initially, Bluetooth technology was primarily used in phones. However, more services will be provided in the future, such as remote vehicle condition diagnosis, vehicle safety systems, vehicle-to-vehicle communications, multimedia downloads, etc. In the future, automotive applications based on Wi-Fi and Bluetooth will bring new opportunities to all walks of life. From silicon suppliers to hardware manufacturers, automakers, gasoline retailers and more.8. In the medical field, most of the applications initially considered for Bluetooth were to replace wired connections. Each medical equipment in the hospital is basically an independent system, so various equipment is equipped with its own computer system, printer and other peripheral systems, which are independently connected through data lines. Therefore, reading machine status, reconfiguring equipment, sensor data, patient data, patient monitoring, secure access data, asset tracking, etc. are all separate systems for security purposes. The most common ones, such as operating rooms and radiology departments, can be found everywhere. Cables are crisscrossed on the ground. Once the instrument fails, doctors need to spend a lot of energy to check whether each interface is well connected along the wires. Organizing these wires is a hassle. This wastes a lot of time. Time is very precious to rescue patients, and words are also very precious. All devices connected with Bluetooth technology solve the troubles of medical device users.Currently, Bluetooth positioning technology still faces many challenges. These challenges will become problems that the industry must face, but the Internet of Things will be the future development trend, and the demand for Bluetooth positioning will be applied on a large scale.

How are smart homes connected and controlled?
The main connection methods of smart home include Zigbee, Wi-Fi, Bluetooth, infrared, etc. The control methods include traditional touch control, infrared induction control, cross-screen control, scene linkage control, etc. We will introduce in detail how to connect and control smart home.1. How to connect smart homes1. ZigbeeZigbee is a new wireless network protocol for low-speed and short-distance transmission. It is suitable for electronic devices with short transmission range and low data transmission speed. Its main features are low power consumption, low cost, low speed, and many nodes. These features are made for smart homes. Low power consumption means that products using it for wireless communication do not need dedicated power supply, and multi-node avoids the situation of too many and unstable devices connected to Bluetooth and Wi-Fi.2. Wi-FiWi-Fi is probably the wireless protocol we are most familiar with and is also the network foundation of smart home platforms. Even with excellent wireless protocols like Zigbee, Wi-Fi communication requires Wi-Fi communication. On the other hand, as the predecessor of wireless protocols, the technology is mature and stable. The Internet represented by Wi-Fi is the only way for devices to connect to the outside.3. BluetoothBluetooth is a common wireless transmission protocol other than Wi-Fi. It is characterized by wide application range, short transmission distance, flexible and low power consumption. In the smart home, Bluetooth plays two main roles, one is to quickly search and discover new devices when accessing the device for the first time, and the other is to realize the interconnection of two local devices, such as the Bluetooth Mesh light group.4. InfraredInfrared, short for infrared, is perhaps the oldest and most widely used wireless transmission protocol that each of us comes into contact with in our lives. It is characterized by point-to-point transmission and no obstacles at close range. It is mainly used for remote controls of home appliances such as TVs and air conditioners. In smart homes, in addition to individual electrical appliances, infrared remote controls are also used. More applications are to use infrared universal remote controls on various smart platforms to access old electrical appliances to achieve intelligent control.2. Common control methods for smart homes1. Traditional touch controlFor users who are accustomed to traditional wall switches, it is not used to directly entering the abstract control method. If the control system also has errors, this basic control method is necessary. For example, the music, lights, air, and curtains at home all have corresponding control panels for control. It can also be controlled via touch screen on the multi-function control panel. Of course, there are also knob controls for fine control of lighting.2. Infrared sensor controlControl via human body infrared is nothing new, but this control was quite practical at the time. For example, after human body infrared sensors are installed in entrances, corridors, balconies, and bathrooms, the lights will automatically turn on after sensing the signal, and automatically turn off after people leave. This is especially friendly to family members who need to get up at night. The night light is turned on when they get out of bed, which can illuminate without affecting other family members who are resting.3. Multi-screen controlJust imagine, the phone is out of battery, how to turn off the kitchen lights in the living room? At this time, cross-screen control is needed to help us! Only one indoor terminal is needed to check the power status of all smart devices in the home in real time, and other devices can also be turned off directly on the indoor terminal.4. Scene linkage controlWith the increase of smart devices on the market, we hope that it will be easier to use, and different devices can assist in the work, and realize the control of smart homes by customizing platform-level smart devices to edit scene modes. For example, our indoor smart terminals. The smart mirror is a platform-level smart device. By connecting to other devices in the home, you can centrally control lights, music, air, hot water, access control, etc. on the smart screen.5. Voice ControlVoice control smart home mainly has two forms: direct voice and indirect voice. Direct voice refers to issuing corresponding voice commands to specific home appliances, while indirect voice is controlled by intelligent control devices controlling the voices of other household devices (smart phones, smart speakers, sound hosts, etc.). Contactless interaction such as voice control is a trend in the post-epidemic era.

What is a fascial gun and what are its functions and uses?
Fascia guns have become very popular in the past two years. Celebrities and athletes are using them to relax their muscles. Fascia guns are also available in some common gyms, and some sports enthusiasts also have spare ones. So what is a fascial gun, and what are its functions and uses? Specifically, Tsinghua Microelectronics will introduce to you:What is a fascia gun?Fascia Gun, the full name of Fascia Gun, is a high-frequency percussion therapy for fascial relaxation. After fitness or exercise, the sympathetic nerves are over-excited, causing the muscles to be too tense when static, causing fascial adhesion, which affects recovery and growth.When fascia is adhered or injured, the body often experiences many uncomfortable reactions: muscle stiffness, hardness, and tightness, local skin temperature is low and moist; muscle tissue is loose, inelastic or has reduced elasticity, and is sunken; subcutaneous and deep muscle layers , There are irregular lumps or cord-like hard tissues between the bone seams. This is a way for the body to protect muscles, and it is also a protective mechanism that hinders muscle recovery, especially some deep muscles that are difficult to reach by foam rollers or vibrating foam rollers.Therefore, these extra excitements must be released through fascia relaxation so that the above problems can be solved and alleviated. Combined with dynamic stretching before training and static stretching after training, the muscles and joints will look better and safer. Compared with our daily use of foam rollers for relaxation, the fascia gun relaxes muscles and fascia more deeply and accurately. This is why the fascia gun program was developed.The principle of the fascial gun and its applicable groups:The fascia gun mainly uses the principle of muscle resonance to strike and vibrate deep muscle tissue deeply, thereby accelerating blood circulation, relieving pain, and accelerating recovery after injury. It is a powerful helper for rehabilitation physiotherapists, pain doctors, masseurs, beauticians, health care practitioners and other related people.How to use the fascia gun:First, make sure the vibration starts before starting the massage. Follow the direction of the muscles when using them, so be sure to memorize the anatomy of the muscles you want to relax. Then choose different tips according to your relaxation areas. Our principle is to push hard and move slowly, for example, hit it a dozen times and then move it. The distance moved each time is very small.Why use a fascia gun?1. It has a certain local weight loss effect. Muscle fat moves under the skin and consumes a large amount of fat, which generates heat energy and is excreted from the body.2. It has the effects of relaxing muscles, activating blood circulation, unblocking collaterals, and providing degree massage. There are no professional and technical requirements for individuals.3. Its high-frequency oscillation effect can penetrate deep into the skeletal muscles, causing the skeletal muscles to relax instantly and the meridians, nerves and blood vessels to become smooth.4. Effectively prevent the masseur's hand skin from contacting the patient's skin and avoid contact skin diseases.Shenzhen Zuchuang Microelectronics Co., Ltd. is an electronic and electrical solution development, design and chip agency company with 19 years of experience.

Sweeping robot solution: working principle and hardware composition
At present, sweeping robots are very popular. Today, we will explain the sweeping robot solution of Zuchuang Microelectronics. Let us understand the working principle and hardware composition of sweeping robots.How does a sweeping robot know what the room looks like with its eyes and ears? Where are the cabinets, shoes, beds, seats, and people in the room? Could he know what these things were? The laser navigation sensor mainly constructs the outline of the reflective object, and uses the outline to compare the approximate reality of the object.The ears of the sweeping robot are actually microphones. With a microphone + a voice intelligence algorithm in the CPU chip, the sweeping robot can answer questions fluently with you.The eyes of the sweeping robot: Lidar. Lidar is mainly used to measure distance and identify objects.Brain + cerebellum, which is the core processor of the sweeping robot: 3 core processors1. The main control chip is mainly used for upper-layer applications. Including the operating system and voice, vision, and UI interface interactions are all managed by the main control chip, such as the quad-core processor of the Allwinner ARM Cortel-A7 architecture used by the Xiaomi sweeping robot.2. The microcontroller is mainly used for path planning. Run the SLAM navigation algorithm to establish a virtual three-dimensional spatial map of the room.3. Digital signal processor. This is mainly to issue instructions to the executing motors after path planning for the control chip, including the steering wheel (the sweeping machine moves forward and turns), the sweeping brush motor, and the vacuum cleaner motor to make these motors work.The brain of the sweeping robot is mainly used for path planning, obstacle avoidance, and human-computer interaction. For example, humans set the cleaning range, and voice guidance of the sweeping robot to clean requires the processor to process and then issue the instructions to the execution mechanism.The cerebellum is the control area closest to the executive layer. For example, as we mentioned above, the latter two processors: digital signal processor and microcontroller are both processors that control the executive layer (motor) and feed back external information.There are three types of actuators for sweeping robots:The steering gear for walking, the motor for sweeping the floor, and the motor for a vacuum cleaner. The dust swept up is sucked into the storage area, which is the working process of the sweeping robot.Therefore, the core technologies of sweeping robot manufacturers in the industry basically focus on laser navigation and path planning, and will also add some humanized designs, such as voice interaction and so on.Shenzhen Zuchuang Microelectronics Co., Ltd. has 20 years of electronic and electrical solution development and design and chip agency company, focusing on the solution design of sweeping robots and mini fascia gun solutions. At the same time, it can provide MCU, voice IC, Bluetooth IC and modules, wifi modules . The development capabilities cover PCB design, single-chip microcomputer development, software custom development, APP custom development, WeChat official account development and other hardware and software design.
