Huacan Optoelectronics also wants to play robots to build 3 million yuan to participate in the North Vision Photon
Huacan Optoelectronics (300323) announced on Friday that it intends to invest no more than RMB 3 million in the company or its wholly-owned subsidiary, with the company’s shareholders, Jing Tian Capital I Limited, and the actual controlling party of Jing Tian Capital II Limited, IDG Capital. The managed funds, Cobos Robotics Co., Ltd. and other investors jointly participated in the capital increase of Beixing (Beijing) Photonics Technology Co., Ltd., which included its capital reserve of 2,994,900 yuan and its newly registered capital of 5,135.49 yuan, accounting for 3.75% of the total registered capital after the capital increase. North Xingguangzi is currently engaged in research and development and sales of radar-related hardware and software products in the field of robotics. According to the announcement, Huacan Optoelectronics aims to expand the company's development space in the third-generation semiconductor applications and expand the company's new application areas.
Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.

Beixing Photon is a high-tech company engaged in machine vision. It has won the “Chunhui Cup†in New York City, and the company stayed at Tsinghua Enlighten Technology Park. The company's start-up team consists of engineers and scientists from Europe and the United States, and the level of products is international. Currently, he is mainly engaged in the design and manufacture of infrared environment radar DE (TOF technology using laser radar) for obstacle avoidance, path planning, and RGBD visual recognition of drones and robots.
What kind of industrial height does the third-generation semiconductor material contain?
Compared with the first second-generation semiconductor materials, the third-generation semiconductor materials have wider band gap, higher breakdown electric field, higher thermal conductivity, higher electron saturation rate and higher radiation resistance. It is more suitable for making high temperature, high frequency, radiation resistant and high power devices. It is also commonly known as wide bandgap semiconductor materials (forbidden band width greater than 2.2 electron volts), also known as high temperature semiconductor materials.
Third-generation semiconductor materials have great advantages in energy density, enabling high output and high frequency, and achieving higher energy in a smaller volume. In the electronically scanned array radar, GaN scanning reaches 5 times the GaAs speed in the same region under the condition of using GaN, or the scanning area is 50% larger than GaAS at the same speed. In the case of GaN, the radar can achieve higher scanning efficiency with a reduction in volume by half.
The development of the third generation of semiconductor technology and R&D in the United States is mainly used to support the new generation of AESA (Active Electronically Scanned Array) radar, new electronic warfare systems and commercial applications.
