Many users who have used smartwatches are tempted: the screen is too small and touch is inconvenient! But then you may not need to worry about this problem because researchers at Carnegie Mellon University recently launched a smart watch that can Your arm also becomes a touch screen! The prototype of this smart watch, named LumiWatch, projects a "touch area" (much like a laser keyboard) on the wearer's arm (or hand), allowing the user to control the watch in this area. For example, in the demo, you can swipe in the projection area to complete the unlock, or browse the application and so on. It is reported that LumiWatch can project a control area of ​​40 square centimeters, which is equivalent to 5 times the size of a normal smart watch screen! It is worth mentioning that the appearance of LumiWatch is not much different from our common smart watches. Circuit boards, projectors, sensors, batteries are wrapped in metal case. The LumiWatch projector projects three colors of red, green, and blue, and it is bright enough for the user to see clearly outside. The LumiWatch Smart Watch completes the tracking of the wearer's finger movements with a built-in 15 lumens scanning laser projector. It also features a Qualcomm 1.2Ghz quad-core CPU, 768MB of memory, 4GB storage, and 740mAh lithium-ion battery, Bluetooth and Wi-Fi support. Run Android 5.1. The researchers said that the watch can project touch screens for about 1 hour. If it is used at the normal frequency, the life of the watch should be sufficient to support one day of wear (one day...). The researchers estimated that the retail cost of the prototype was about $600 and the size was 50mm x 41mm x 17mm (2 inches x 1.6 inches x 0.66 inches), which is much larger than the 42mm Apple Watch Series 3 with the aluminum case. In fact, as early as two years ago, the Future Interaction Research Group at Carnegie Mellon University proposed a program called SkinTrack. The smartwatch is equipped with a set of sensors, and the user's operating finger must wear a matching ring. When the operation finger touches the skin wearing the wrist of the watch, a bioelectric signal will be sent out through the skin. The watch will measure the position of this signal on the arm according to the distance between the touch point and the four sensors on the watchband. This system can even recognize gestures. For example, drawing an “S†on the arm can mute phone calls; and it also supports floating operations... Relatively speaking, the solution adopted by LumiWatch is quite mature. Stator Core welding is a important process for stator core assembly. We are able to use TIG, MIG, LASER weld to meet different requirement for customers. The stator core is an important part of the stator and the main component of the magnetic circuit of the motor. Different sizes of stator cores have different technological processes and application fields. For example, small-sized stator cores are usually assembled by interlocking, and the outer diameter is usually less than 200mm. Large-sized stators are assembled in different ways depending on the motor design, such as stator core by cleating and staor core by welding.
