Remember the fact that American Airlines Flight 1549 was forced to land on the Hudson River after suffering a bird strike? The plane that hit the plane was a group of Canadian geese. Because the visual stimuli of birds are very different from those of humans, it is difficult to prevent them from flying into the route by conventional methods. But now science brings us a solution. That is the LED light flashes. Researchers at the US Department of Agriculture, Indiana State University, and Purdue University have just published a paper that they are looking for ways to scare off birds that are close to the aircraft. The research team sent three radio-controlled aircraft, one of which was a normal aircraft model, one disguised as a predator, and the last with flashing alternating pulsed LED lights at 2 Hz. The results show that when the lights are flashing, the birds will quickly notice the aircraft and avoid it, which is better than pretending to be a predator. It seems that only a simple thing to flash the LEDs can reduce the billions of dollars in the annual aviation industry. I think the airlines may adopt this solution after hearing this report!
Metal Film resistor is Film resistor (Film Resistors) of a kind.It is the high temperature vacuum coating technology will be closely attached to the porcelain nickel chromium alloy or similar bar surface skin membrane, after debugging cutting resistance, in order to achieve the final requirements precision resistance, then add appropriate joint cutting, and on its surface coated with epoxy resin sealing protection.As it is a lead resistance, it is convenient for manual installation and maintenance, and is used in most household appliances, communications, instruments and instruments.
