Worthy of Disney's lightsaber war with IR LED

Disney is about to launch a 56 thousand square meter Disney Star Wars Park in California in the next few years, which will surely make tourists hooked. In fact, a new patent in the near future is closely related to how to let lightsaber fight in the dark. A website called PatentYogi posts a patent application by Disney company, sometimes called the "audience interaction plan system". It may sound complicated, but it seems that Disney has devised a system that allows fans to brandish the laser light knife. The system may be applied to other aspects, but the patent itself is very clear: (photo source: Disney patent application) this patent is a LED light mounted on the lightsaber, allowing LED lights to interact with the UAV above the spiral. According to Disney's design, the light knife is equipped with a row of IR LED, which can communicate with the IR receiver on the UAV. As long as the LED is turned on, the sensor of the invisible light on the UAV can be judged by the signals emitted by the IRLED on the light knife to capture the planes in the environment. The light knife in this system can enable multiple LED at the same time, and successfully create the surface of the lightsaber. Disney sent a patent application in January 13, 2015 and released the patent in July 14, 2016. Following the successful creation of VR virtual reality devices by different manufacturers using IRLED features, Samsung also installed iris identification system on Galaxy Note 7 and more and more IRLED applications, which will also enable IRLED manufacturers to continue to see demand.
