摘要： The present disclosure provides a dual-seal reverse pressure differential cartridge E-liquid injection method. The method includes: selecting an E-liquid guiding body configured to absorb, to a maximum degree, an E-liquid stored in an E-liquid storage tank, to avoid leakage of the E-liquid, while providing a smooth supply of the E-liquid. The method also includes assembling the E-liquid guiding body with a cartridge that includes an E-liquid storage tank. The E-liquid guiding body is in fluidic communication with the E-liquid in the E-liquid storage tank. In a negative pressure environment, the E-liquid is injected into the E-liquid storage tank. The E-liquid has a pressure P1. After the injection is completed, the cartridge is placed in a sealing bag, which is then sealed. The pressure inside the sealing bag is P2, P2>P1. The disclosed method can effectively avoid leakage of the E-liquid due to pressure changes in the external atmosphere.

摘要： A power conversion system for converting thermal energy from a heat source to electricity is provided. The system includes a chamber including an inner shroud having an inlet and an outlet and defining an internal passageway between the inlet and the outlet through which a working fluid passes. The chamber also includes an outer shroud substantially surrounding the inner shroud. The chamber includes a source heat exchanger disposed in the internal passageway, the source heat exchanger being configured to receive a heat transmitting element associated with the heat source external to the chamber, and to transfer heat energy from the heat transmitting element to the working fluid. The system also includes a compressor disposed adjacent the inlet of the inner shroud and configured to transfer energy from the compressor to the working fluid, and an expander disposed adjacent the outlet of the inner shroud.

摘要： A device includes a light guide and at least one in-coupling element configured to couple an image light into the light guide. The device also includes a first out-coupling element configured to couple a first portion of the image light out of the light guide as a plurality of first output lights. The device further includes a second out-coupling element spaced apart from the first out-coupling element by a distance and configured to couple a second portion the image light out of the light guide as a plurality of second output lights. The second output lights are substantially non-overlapping with the first output lights.

摘要： A method includes acquiring an image through a visual sensor during a movement of a mobile device. The method includes matching the image with key frames stored in a key frame database. The key frames are created based on two-dimensional coordinates of feature points included in a plurality of images previously acquired through the visual sensor. The method also includes computing a visual relative pose based on two-dimensional coordinates of matching feature points included in both of the image and the one or more key frames that have been matched with the image. The method also includes computing relevant information of the visual relative pose based on the two-dimensional coordinates of the matching feature points. The method further includes updating an absolute pose of the mobile device and a map based on the relevant information of the visual relative pose and relevant information of a dead reckoning based relative pose.

摘要： A system is provided. The system includes a waveguide configured to guide an image light to propagate inside the waveguide. The system also includes a plurality of diffractive components coupled to the waveguide and switchable between operating in a diffraction state to direct the image light from the waveguide to an eye-box of the system, and operating in a non-diffraction state to transmit a light from a real-world environment to the eye-box. The system further includes a controller coupled with the plurality of diffractive components and configured to switch each of the plurality of diffractive components between operating in the diffraction state during a virtual-world subframe of a display frame and operating in the non-diffraction state during a real-world subframe of the display frame.
