Abstract: A patrol and inspection vehicle includes a vehicle body, distance measuring devices installed on front and rear sides of the vehicle body for detecting distances of ambient objects, a LiDAR sensor installed on the vehicle body for constructing a three-dimensional spatial model for positioning and navigation, a panoramic camera installed on the vehicle body for recognizing images of ambient individuals, and a gas detector installed on the vehicle body for detecting leaked gases having a temperature different from room temperature. The patrol and inspection vehicle can automatically inspect whether there are gas leaks in pipelines and detect if individuals have accidentally entered restricted areas, thereby reducing the manpower required for patrols and enhancing factory safety.

Abstract: A method for maintaining lamellar structure of cell, configured to manufacture a lamellar cell product, comprises the following steps of: seeding a predetermined number of cells in a culture device containing a first culture medium and culturing the predetermined number of cells for a predetermined time to form a cell planar structure; placing a mold in the culture device to cover at least an outer portion of the cell planar structure; adding a gel into the culture device with the mold to envelop the cell planar structure; and separating the gel and the cell planar structure enveloped therein from the culture device and the mold to form the lamellar cell product.

Abstract: Provided is a smart locker, including a cabinet, a plurality of locker doors, and a plurality of shelf boards configured to vertically divide a storage space of the cabinet into one or more locker compartments. In some examples, each of the one or more locker compartments includes a locker door of the plurality of locker doors. Moreover, when a locker door of a first locker compartment of the one or more locker compartments that is adjacent to a second locker compartment of the one or more locker compartments is closed, a position of a shelf board of the plurality of shelf boards that forms the first locker compartment is limited by the locker door of the first locker compartment.

Abstract: A screen protector includes inner and outer PET films, a printed black-frame film, a PET release film, and a PE protective film. The inner PET film has a printed peripheral area for electrostatic attraction and a transparent central area. The printed black-frame film has a frame-like peripheral area coated in the desired color and shaped as the printed peripheral area of the inner PET film. The inner PET film, the printed black-frame film, and the outer PET film are sequentially bonded, before the PET release film and the PE protective film are bonded to the inner and outer PET films respectively. The screen protector can be cut to size and formed with holes at predetermined positions. To apply the screen protector to a screen, the PET release film is peeled off, allowing the printed peripheral area of the inner PET film to attach compliantly to the screen by electrostatic attraction.

Abstract: An adhering jig and an adhering method for screen protector plastic sheets are provided for encapsulating and packing, by means of the adhering jig capable of safe coverage, screen protector plastic sheets intended to protect the surfaces of panel cell phones against scratches inflicted by foreign bodies, in the course of delivery or sales after being manufactured by a manufacturer, so as to preclude contact with and prevent dents, bends, or damage from occurring to the screen protector plastic sheets and covering the surfaces of the panel cell phones with the screen protector plastic sheets by means of the packing-oriented adhering jig to achieve precise smoothness and flawless attachment.
