Abstract: The present invention provides a lace fabric of a helical structure containing twisted optical fiber threads and a production method therefor. The lace fabric comprises light guiding threads, an external sleeve and braided ropes. The light guiding threads and the braided ropes are mutually twisted to form a whole body; the external sleeve is further sleeved outside the light guiding threads and the braided ropes; an LED light source module is arranged at the outer parts of the light guiding threads and the braided ropes; and a light-emitting end of the LED light source module and the light guiding threads are arranged opposite to each other. The present invention is safe, is low in cost, is conveniently applied to and combined into various daily supplies, is used in some spaces with little light, such as outdoors in the night and other places.

Abstract: The present invention provides an alarm system for monitoring a physical disorder of a user during an immersive virtual reality (VR) experience. The alarm system includes a physical information monitoring module, a control module, a display module, an alarm module, and a power module. The control module is configured to receive the human body physical sign information transmitted by the physical information monitoring module and feed back the information to the display module and the alarm module. When a user wearing a VR device has an adverse physical response during an experience and use, the alarm system of the present invention can quickly transmit a corresponding warning and prompt according to a detected abnormal physical sign. If the user has an adverse physical response and cannot carry out self-help, a remote call for help can be quickly made through software, thereby providing maximum protection for the user.

Abstract: The present invention provides a portable charging light-emitting cable for new energy vehicles, including power configuration wires, a signal wire, electroluminescent wires, a filling layer and an outer protective sleeve. The power configuration wires are evenly arranged around the signal wire. At least more than two electroluminescent wires are mutually helically twisted with the power configuration wires in the same number of groups around an outer wall of the signal wire into a cable shape. Each electroluminescent wire is arranged between two adjacent power configuration wires. According to the present invention, the electroluminescence technology is incorporated into light-emitting charging cables. While charging, cables emit light evenly, which is suitable for charging observation at night, and rich colors are provided to play a warning role to prevent accidents. During the light-emitting process, light-emitting wires do not generate any heat, and energy consumption is extremely low.
