Abstract

A head-mounted device comprises a main body, a monitor-base, a monitor, and an adjusting component. The main body is mounted on a user's head. The monitor moves with the monitor-base. An eyes-monitor distance is defined between the user's eyes and the monitor. A visual range is defined by a range seen by the user's eyes through the monitor. The adjusting component is configured for pulling or pushing the monitor-base towards the user's eyes to prevent the eyes-monitor distance from increasing and to prevent the visual range from decreasing. When the user wears a pair of glasses between the user's eyes and the monitor, and the glasses block the monitor causing the eyes-monitor distance to be larger than a preset distance, the adjusting component pulls or pushes the monitor-base until the monitor contacts the glasses, to prevent the eyes-monitor distance from increasing.

Abstract

A method for obtaining depth images for improved driving safety applied in an electronic device processes first and immediately-following second images which have been captured and processes each to obtain two sets of predicted depth maps. The electronic device determines a transformation matrix of a camera between first and second images and converts the first predicted depth maps into first point cloud maps, and second predicted depth maps into second point cloud maps. The first point cloud maps are converted into third point cloud maps, and the second point cloud maps into fourth point cloud maps. First and fourth point cloud maps are matched and first and second error values are calculated, thereby obtaining a target deep learning network model. Images to be detected are input into the target deep learning network model and depth images are obtained.

The lifting mechanism is applied to a robot, the robot comprises a controller, the controller is electrically connected with the lifting mechanism. The first detection element and the second detection element detect a height of the at least two guide rods, the controller controls the lifting member to move up or down according to the first position signal output by the first detection element and the second position signal output by the second detection element, so that the lifting mechanism can accurately locate the highest ascending position and lowest descending position of the lifting mechanism. A robot is also provided.

Abstract

A method for extracting text relevant to a particular topic from a document to generate a narrower, condensed, more specific, and smaller version obtains information as to the text of a large document and searches the text information of the document based on first keywords to extract first pages. The first pages are inputted into a predetermined learning model to extract second keywords from the first pages, and the first keywords and the second keywords are integrated to obtain third keywords. The method further searches the text of the first pages based on the third keywords to extract second pages and a determination is made as to whether the second pages meet a predetermined page standard. If yes, the second pages are integrated and output. An electronic device and a non-transitory storage medium are also disclosed.

Abstract

A display device includes an optical assembly for displaying images, a frame, and an adjustment assembly including a spherical bearing a connecting rod, and a cover. The frame and the optical assembly are arranged at intervals, a first recess is concave in a first direction from the frame, a through hole penetrates the frame and communicates with the first recess; a part of the spherical bearing is received in the first recess and abuts against an inner surface defining the first recess; the connecting rod extends through the through hole, one end of the connecting rod is fixed to the spherical bearing, and the other end is connected to the optical assembly; the cover is arranged on a side of the spherical bearing facing away from the frame and adjustably connected to the frame in the first direction to selectively apply or remove a pressure to the spherical bearing.

Abstract

The disclosure provides a composite cathode for a solid-state battery, which includes a composite layer and a solid electrolyte layer. The composite layer includes a cathode sheet, an interface layer and an ion conductor. The interface layer is disposed on the cathode sheet. The ion conductor is disposed between the cathode sheet and the interface layer, or dispersed in the cathode sheet and the interface layer. The solid electrolyte layer is disposed on the composite layer.
