February 27th According to foreign media (CNET), two Indian employees of Garmin, a navigation GPS manufacturer, were shot in the bar in Kansas, USA, on the evening of last Wednesday. The suspect was identified as the 51-year-old American Adam. · Adam Purinton.
The Washington Post reported that after being kicked out of the pub, Princeton returned home with guns and shot at two victims, Kuchibhotla and Madasani. Another person who tried to intervene in the intervention was also shot. Of the three victims, only Madasani survived.
Princeton has now been arrested and charged with first-degree murder and two counts of attempted first-degree murder.
The survivor Madasani told the New York Times that the murderer had talked about racially sensitive issues.
"He asked us what type of visa we are currently and whether we are illegally detained," Madasani said. The Post also reported that Princeton shouted "Get out of my country." In fact, both 32-year-old victims were educated in Kansas and legally employed.
Although Princeton's mother said that her son's behavior is inconsistent with his usual behavior. However, some people believe that such aggressive killings reflect the anxiety and exclusion of foreign immigrants in the United States in recent years.
The incident occurred at the Olasi City Police Station in Kansas and did not immediately respond to requests for comment. A Garmin spokesperson stated that the company held a vigil for the dead on Sunday.
“Garmin is a global family with colleagues from different countries and religious backgrounds. We are proud to embrace our differences,†said the spokesperson. "Our diversity helps foster new ideas and makes Garmin a strong company."
She added that the company will continue to provide support to the families of the affected employees during this difficult period.
Satya Nadella, Microsoft’s chief executive who is himself a native of India’s immigrants, stated his position on personal tweets on Friday: “There is no room for meaningless violence and paranoia in our society. My The heart is with the victims of the terrorist shootings and their families."
American technology companies have a large number of overseas employees, many of whom are from India. In addition to Nadella, Google’s current CEO, Sundar Pichai, also came from India. It is estimated that up to 15% of technology startups have Indian employees.
After the tragedy, the survivor Madasani’s father urged his son to return home as soon as possible.
“The situation seems very bad after Trump took over as President of the United States. I call on Indian parents not to send their children to the United States in the current situation.â€
FBT WDM - Fused Biconic Taper Wavelength Division Multiplex
A fusion taper type wavelength division multiplexer, comprising an input end cone, an output end cone, and a coupling area. The input end cone is located at one end of the coupling area, and the output end cone is located at the coupling area. At the other end of the zone, the input end cone includes an input arm and a backscatter arm, the output end cone includes a through arm and a coupling arm, and the optical power is input from the input arm of the input end cone through the The coupling zone is redistributed after coupling and output from the output end cone. A part of the optical power is output from the through arm and the other part is output from the coupling arm. The coupling zone includes two optical fibers, and the cladding parts of the two optical fibers are mutually connected. Close, when pulling the taper, the two optical fibers are pulled in opposite directions but cannot move relative to each other. The two optical fibers are processed by a fusion taper device.
At present, the method of making FBT WDM in industry is to use a flame to heat and melt the fiber at a single point and then stretch it. The defect is that the heating area is too short, resulting in a short stretchable length (corresponding to the coupling length), and the fiber diameter is not small enough, so This limits the minimum channel spacing that this type of wavelength division multiplexer can achieve.
FBT WDM, also known as Fused Biconic Taper WDM and FBT WDM Splitter, along with LAN WDM Splitter, Filter WDM splitter, dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
Further, the melting taper device is formed by two insulation bricks made of aluminum oxide fiber insulation material to form a cavity, and the high temperature heat source is provided by an electric heating wire made of molybdenum disilicide material, and the heating wire is located In the heating tank, the heating temperature is adjusted by adjusting the voltage at both ends of the electrodes connected to it, the optical fiber passes over the heating wire, and the taper speed is adjusted by changing the rotation speed of the programmable stepping motor driver.
Further, the two optical fibers are fused and tapered in the fusion tapering device, one of which is used as the input power of the input arm, and the other is used as the coupling arm fiber. After the tapering length reaches a certain distance, the two fibers are coupled, and the optical power is Continuously couple into the coupling arm fiber, continue to taper, and the optical power is repeatedly and alternately coupled in the two fibers.
