Huazhou shares with you the application case of phone wireless charging coil positioning
Wireless charging system mainly adopts electromagnetic induction principle to realize energy transfer through coil energy coupling. (primary coil) through the alternating current, the secondary side (secondary coil) will induce the electromotive force due to the principle of electromagnetic induction, if the secondary side circuit is connected, the induction current can appear, so that the wireless transmission of electric energy from the transmitting coil to the receiving coil can be achievedMore

Vein indwelling needle online tip defect detection scheme
In 1962, the German company Braunule invented the first indwelling needle "Braunule". Because the use of indentation needle can reduce the pain caused by repeated venous puncture in sick children, and then reduce the fear of injection, which is convenient for clinical medication, especially for emergency and critically ill patients.More

The moon group Luan day, when the whole family gathers It's the fifteenth day of the eighth lunar month Mid-Autumn Festival Three autumn osmanthus ten miles lotus It's the most poetic time of the year
With the improvement of people's living standards, a variety of packaging has been more and more into our sight, the domestic packaging has been in the national economy important industries.
With the rapid development of science and technology, the technology of uncooled detector is becoming more and more mature, long wave infrared uncooled optical system has been widely used in military and civil fields. Since infrared optical materials and mechanical materials will produce thermal changes when the temperature changes, the change of working environment will cause the focal length change of the optical system, the image surface is elegant, and the imaging quality is reduced.
Triode is one of the basic components of semiconductor, has the effect of current amplification, is the core component of electronic circuit. The transistor is in a semiconductor substrate to produce two PN junctions very close to each other, the two PN junctions divide the whole semiconductor into three parts, the middle part is the base region, the two sides of the part is the emission region and the collector region, the arrangement of PNP and NPN two kinds.
With the development and progress of society, industrial production and People's Daily life have a greater demand for energy. Bluetooth headphones break through the wired mode of traditional headphones, and the function of freely answering the phone anytime and anywhere is favored by users, especially business personnel.
The Dragon Boat Festival, also known as the Duanyang Festival, Dragon Boat Festival, Tianzhong Festival, etc., originated from the natural sky worship, from the ancient times to sacrifice dragon evolved. In the middle of the summer Dragon Boat Festival, Canglong seven nights soar to the south of the central sky, in the most "central" position throughout the year, such as the fifth line of the Book of Changes
◆ Miniaturization、High quality design; ◆ High brightness, light source brightness can reach more than 5000lx; ◆ High uniformity, uniformity >85% within the range of working distance;
The manufacturing process of semiconductor chips can be divided into sand raw materials (quartz), silicon ingots, wafers, lithography, etching, ion implantation, metal deposition, metal layer, interconnect, wafer testing and cutting, core packaging, grade testing, packaging and many other steps.
With the development and progress of society, industrial production and People's Daily life have a greater demand for energy. The emergence of new energy has greatly changed people's excessive dependence on traditional energy.
