It's worthy of the Disney lightsaber war with IR LED

Disney is going to launch a 56 thousand square meter Disney star war Park in California in the next few years, and it is sure that visitors will be hooked. In fact, there is a new patent in the near future that is related to how to make the lightsaber duel in the dark. A web site called PatentYogi posted a patent application for Disney, sometimes called the "audience interaction plan system". It may sound complicated, but it looks like Disney has designed a system that allows fans to waving laser blades. The system may be applied to other aspects, but the patent's own drawings are very obvious: (photo source: Disney patent application) the patent is a system that puts the LED lamp on the "lightsaber" and allows the LED light to interact with the UAV over the hovering. 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 opened, the unvisible light sensors on the UAV can be judged by the IRLED emitted by the light knife to capture the surface of the environment. The optical knife in this system can simultaneously enable multiple LED and successfully create a lightsaber surface. 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 applications of IRLED. It will also allow IRLED vendors to continue to see the requirements.
