The rapid development of my country's UAV technology over the years is simply a scene of "a hundred flowers blooming". However, the Dark Sword UAV that appeared 12 years ago has not moved. Recently, the Internet first exposed large-size photos of the Dark Sword UAV, which immediately attracted great attention at home and abroad. In 2006, China's Dark Sword UAV was silent after its first public appearance. This made people question whether there was a situation, but after all,...
Scientists generate electron couplers under controlled conditions at low temperatures. Researchers at the University of California, Riverside recently reported that they have discovered a new method for generating electron couplers at low temperatures. The study of electron couplet helps to reveal more properties of antimatter, and the mystery of why nature favors matter over antimatter when the universe was created. Relevant papers will be published in "Physical Review Letters"...
The efficiency of the conversion of the conduction mode into the cladding mode in the fiber k is the condition that no radiation occurs. D is the diameter of the nth reflection of the light in the tapered fiber: where is the angle between the incident light and the fiber axis, which is the tapered fiber Angle of half cone. n and n are the refractive index of the core layer and the cladding layer, n is the number of reflections in the core when the light becomes leaking light, and l is the...

In many high-frequency transmitting equipment, a directional coupler is often inserted in the path from the final power amplifier to the transmitting antenna to measure the transmitting power of the transmitting device or the reflected power of the antenna. Below I introduce the working principle of this directional coupler . Figure X is the principle diagram of the directional coupler, where A and B are the inner conductors of the main feeder cable, and a coil L3 is placed near the inner...
Industrial communication design engineers need to send high-speed data through the communication field bus while avoiding damage to sensitive controllers, analog-to-digital converters, or sensors. Fairchild Technology Marketing Deputy Manager Zhang Ruibin introduced that the existing solution is to use two single-channel optocouplers, or other technologies such as magnetic and capacitive coupling, but such methods cannot achieve the required reliable isolation level and anti-electromagnetic...
[ China Agricultural Machinery Industry News ] Motor roar, wing flying, various types of plant protection drones over the rice fields you come and go, spraying pesticides. From September 5th to 6th, China Agricultural Film and Television Center (CCTV-7 Agricultural Program), China Agricultural University, and Zhongguancun Tonghang Intelligent Equipment Technology Innovation Alliance jointly sponsored the theme of “Innovative Technology, Creating Miracles”. Man-machine and robot application...
Yu Jingbing, vice president of Shenzhen UAV Industry Association, announced on behalf of the association Global Hawk (Shenzhen) UAV Co., Ltd. promises to take the lead in safe flight Once the drone flight has a problem, it will be a disaster for ourselves and the industry! We sincerely hope that the country's drone manufacturers, research institutions, industry users, and drone drivers will actively support and abide by the initiative. We hope that our vast number of drone companies will...
In rural land security, the local government departments provide local image maps with low resolution and insufficient precision, which cannot be used as a work base map. In order to obtain a suitable image map of the scale, the low-altitude aerial photography technology of the UAV has become the most important means at present. The surveying and mapping drone can perform full coverage aerial photography with a resolution of 0.05 meters, select the ground control point for orthorectification,...
Torque signal coupler use precautions: 1. Wiring must be correct; 2. Range of ±15V: not less than ± 14.5V and not higher than ± 15.5V; 3. The signal line output must not be grounded, shorted to the power supply, and the output current is not more than 10mA; 4. The shield of the shielded cable must be connected to the common (power ground) of the ±15V power supply. 5. The coupler elastomer is very small, strictly limiting overload, overload range ≤ 20%, otherwise it is extremely vulnerable. 6....
Friends who have come into contact with wireless bridges probably know that wireless bridges need antennas. Whether they are built-in antennas or external antennas, antennas are always needed to use them. So why do wireless bridges need antennas? How to choose the right antenna? Professional wireless bridge equipment and solution provider Feng Runda introduce. Principle of wireless bridge signal transmission: RF signal power output from the transmitter bridge is transmitted to the antenna...
Carrier grade couplers are optical devices that enable the distribution or combination of optical signal power between different fibers. It is composed of the mutual exchange of the guided wave energy in the core region of the fiber by using different fiber faces. According to the type of fiber used, it can be divided into multimode fiber, single mode fiber and polarization-maintaining coupler. Generally, a detachable connection between the optical fiber and the optical fiber is used. The two...
As an economical CNC system of SIEMENS, the 828D system has been widely used in various small and medium-sized CNC machine tools. More and more machine tool factories have chosen this moderately priced, high-performance CNC system to replace the 840Dsl system while meeting performance and control requirements. The 828D has also recently developed a dual channel function that is currently only used on lathes. The double-sided crankshaft end machining center SUC8114 independently developed by...
Lynx Box is better than the other generation, is the wireless receiver weak point, opened it, that antenna, too pitiful, just a little bit. Buy SMA connector and SMA antenna, modify it. After the change, the signal was much more stable, especially when it was separated by 2 concrete walls. It also looked at the iQIYI HD/Blu-ray regular card and it is now much better. See another tutorial on antenna reconstruction and share it with everyone. Detailed steps I have edited in the picture! For...
