On March 20th, according to foreign media reports, Apple was granted a new patent on Tuesday. The patent allows mobile or other devices to display data information related to a certain object when pointing at the object. Apple described the patent as "synchronous, interactive, multi-function device augmented reality display technology." The US Patent and Trademark Office officially granted Apple this new patent on Tuesday. According to the latter patent application illustration, the augmented reality display technology can display real-time information about real objects in the video when the device plays live content. Apple also cited an example in the patent application: a user pointed the camera of a device to the computer circuit board, so the components on the circuit board were captured and played by the camera in real time, but the content being played did not only include The picture of the circuit board and the information related to each component are also displayed on the picture displayed in real time. This patent is similar to augmented reality display technologies such as Google Glass and Nokia City Lens, but Apple also provides interactivity, which obviously goes further in this field. Users can create their own annotations by text or drawing while playing video. You can even share these notes with others as a virtual way of collaboration. Apple's technology also supports split-screen display, which displays real-time captured images and related information on a general screen, and at the same time displays computer-generated 3D images and related information on the other half of the screen. The picture can even be shared with others. This function will be very useful when guiding other people, or indicating the attractions of a public place. Although Apple's new patent uses smartphones as a demonstration example, the company also clearly stated in the application documents that a variety of devices including PCs, tablets, game consoles and multimedia players are suitable for this technology.
The low-voltage transformer mainly uses the principle of electromagnetic induction to change the AC voltage. Its main functions are voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization. The low voltage transformer is the transformer below 600V. Low-voltage transformer is composed of three parts: primary coil, secondary coil and iron core (magnetic core). It is usually used in electrical equipment and wireless circuits as a tool for raising and lowering voltage, matching impedance, and safety isolation.
