Lightwave improves cochlear implant, Taiwan enterprises enter Europe and the United States automotive lighting market, Cree appointed new chief financial officer
Amelioration of cochlear cochlea by light wave
At present, about 500 thousand hearing impaired people around the world use electronic equipment to restore some hearing. Cochlear implant is one of them. Led by Tobias Moser, a hearing neuroscientist at the German University of song Ting root, researchers will improve the light in the hope of breaking through the limitations of existing cochlear cochlear.
The cochlea is the spiral structure of the inner ear, which can analyze the frequency of sound. The different frequencies in the speech cause the membrane of the cochlea to vibrate, and the vibrations will activate the cells similar to the "hair", stimulate the hearing neurons, and transmit the related information of the sound through the auditory nerve to the brain.
In sensorineural deafness, hair-like cells are lost, so electrodes are used to stimulate neurons through the cochlear implant. However, because the current produced by the electrode is not a straight line to the hearing neuron, it will be dispersed through the process, so if the electrode is too close, the crosstalk interference will occur. Therefore, the current cochlear implant restricts the number of electrodes to avoid interference with each other, but it also limits the user's hearing performance.
The Moser team used optical genetics technology (Optogenetics) to replace electrodes with light. Photogenetic technology is often used in animal research. It can stimulate genes to produce photosensitive proteins into neurons and stimulate neurons through light.
The research team took gerbil as the experimental object to transform the rat gene into a mouse, shorten the recovery time needed for the two activation of retina protein, then injected the bacteria into the gerbils cochlea, and then put the retina protein gene into the hearing neuron, and then use the optical fiber to enter the cochlea through the round window in the ear. Results in the gerbils, the auditory part of the brainstem was similar to that of the stimulus.
At present, the research team uses only one light wave, and the next step will develop a device that can produce multiple light waves. The device may be designed to use Micro LED array or waveguide technology to guide the light produced by optical fiber. Because optical fiber consumes a lot of electricity, it is expected that the device will be very cumbersome. Daniel Lee, an otologist at Harvard Medical School, points out that LEDs are a good choice, but the light is relatively blurred, so there is a need for technological breakthroughs.
LED enterprises in Taiwan enter the European and American automotive lighting market.
It is reported that, in order to avoid the price competition with Chinese mainland LED suppliers, the LED automotive lighting products of the companies such as Eden optoelectronic, Lian Jia optoelectronic and 100 million optoelectronics have quietly entered the supply chain of European and American auto manufacturers.
China has become the largest new car market in the world. At the same time, domestic Hongli Chi Hui, Ruifeng optoelectronic, Guo Xing photoelectric and Changzhou Xingyu light Limited by Share Ltd have all expanded their share of the domestic LED auto lighting market.
Edison photoelectric China subsidiary now provides LED lighting modules for American carmakers and after market suppliers for direction indicators, daytime traffic lights and taillights. Edison Optoelectronics in the second quarter of 2018 LED automotive lighting revenue accounted for 24.3% of the company's overall revenue, revenue is expected to gradually rise to 30%.
Lian Jia optoelectronics 75% revenue from the North American market, has now occupied the North American LED automotive lighting module market share of nearly 10%. According to the industry, the Flex-N-Gate headquarters in the United States, the Hella KGaA Hueck based in Germany and the Magna International headquarters in Canada are the three largest customers of the company. To increase the supply of the North American market, Lianjia Optoelectronics will combine its existing marketing base with the Michigan warehouse in the second half of 2018 to build a new plant. The plant will have an automated production line and a design center and will be operational by the end of 2019.
The LED auto lighting module, which is produced in the new plant in central Taiwan, is provided to American and European auto makers and is expected to rise from about 5% in 2017 to more than 10% in 2018. At present, billion optoelectronics is also expanding the production capacity of the LED automotive lighting module, which is scheduled to be completed by the end of 2018.
Cree appointed the new chief financial officer
Yesterday, CREE (CREE) announced the appointment of Neill Reynolds as chief financial officer (CFO), which came into effect in August 27th. According to the transitional plan announced in June, Reynolds will replace Mike McDevitt.
Previously, Reynolds served as senior vice president of finance, strategy and procurement at NXP Semiconductors N.V. In NXP, Reynolds has led the global team to develop and promote profit plans, expand company profitability and achieve growth targets.
Prior to joining NXP, he had been the financial director of several international technology companies for more than 15 years, including GE. He serves as chief financial officer in a number of technology industries and serves as a management team, providing sustained profit growth for global industrial and manufacturing businesses.
Night view lighting, Chinese performance advance
Last night (23), Sichuan China body lighting Polytron Technologies Inc (hereinafter referred to as "Chinese science and technology") issued a bulletin, disclosing the first half of 2018 performance advance announcement.
According to the announcement, the company expects to realize the net profit belonging to the listed company in 1-6 months of 2018 30 million yuan -3300 million yuan, compared with the same period of 15 million 901 thousand and 815 yuan in the previous year is expected to increase 14 million 100 thousand yuan ~1710 million yuan, up 88%~107% over the same period.
In addition, the net profit of non recurrent profit and loss attributable to shareholders of Listed Companies in 1-6 months of 2018 is 26 million 100 thousand yuan -2910 million yuan. Compared with the same period of the previous year, it is expected to increase 13 million 250 thousand yuan ~1625 million yuan, up 103%~126% from the same period.
The main reason for the increase in performance in the reporting period is that in the first half of 2018, in the first half of 2018, the company took a positive sales strategy, accelerated the research and development of new products, and further increased the income of the lighting project of the night scene. In addition, the investment income generated by the company using funds raised and idle funds to purchase financial products is about 3 million 800 thousand yuan.
