  • Patent number: 10841567
    Abstract: The present disclosure discloses a virtual reality (VR) helmet and a method for using same. The virtual reality helmet has two optional playing modes: playing a VR video stored in the storage module, or playing a VR video inputted by the video input device when it is detected that the video input device is connected. Therefore, the VR helmet does not only have the function of inputting a video in a wired way in traditional helmets, but also can play a video which is stored in advance locally, so the user can move around freely without the limitation of the wired input when a local video is played. In a preferred embodiment, the VR helmet, by having a proximity sensor used to monitor the wearing state of the user, enters a standby mode and turns off the display module to reduce the power consumption of the helmet when it is detected that the user takes off the helmet, and exits the low power consumption standby mode and turns on the display module when it is detected that the user is wearing the helmet.

  • Publication number: 20200353760
    Abstract: In one embodiment, a high-speed, closed-loop fabric printer comprises a plurality of consecutive stations that can be managed by a single operator. In particular, shirts or other fabric garments may be individually loaded and secured on a pallet by an operator, and the loaded pallets may then cycle through a plurality of unmanned stations positioned along a contiguous path (e.g., oval). The stations may be configured for pretreating the fabric surface, drying and pressing the pretreated fabric with heat, and then inkjet printing a selected image, among others. In this manner, a “wet-to-dry-to-wet” direct to garment (DTG) printing process may thus be achieved, along with optimal controls for maximum adaptability. Furthermore, due to the closed-loop design, a recently printed fabric product returns to the operator to be unloaded at the position in which a new unprinted fabric is loaded, allowing for increased throughput and minimal operator requirements.
