  • Publication number: 20250150571
    Abstract: The invention relates to a display device which comprises a light source, a grid structure and a photo interrupter. The grid structure is disposed above the light source and can move left and right relative to the light source. When the grid structure does not block the photo interrupter, the light source receives a first signal, and when the grid structure blocks the photo interrupter, the light source receives a second signal.

  • Publication number: 20240224315
    Abstract: A method of bandwidth part (BWP) management for a network is provided. Position information of user equipments is received. Whether interference exists between any two of the user equipments is determined based on the position information of the user equipments and the position information of the base stations to obtain an interference status of the user equipments. Interference exists between user equipment(s) of any two base stations in each of the at least one base station combination. Interference exists between a first user equipment and a second user equipment in a first base station combination. BWP resource allocation is performed based on the at least one base station combination and the interference status of the user equipments to obtain a BWP resource allocation result. The first user equipment is assigned with a first BWP frequency band and the second user equipment is assigned with a second BWP frequency band.

  • Patent number: 12021941
    Abstract: A method for obtaining enrichment information and a controller are provided. The method includes: querying, by an enrichment information handling circuit, whether a database stores a first enrichment information corresponding to a user device in response to the enrichment information handling circuit receiving a first creation request associated with the user device from an application; triggering, by the enrichment information handling circuit, the application to subscribe to the database for enrichment information corresponding to the user device in response to determining that the database stores the first enrichment information corresponding to the user device; and pushing, by the database, second enrichment information to the application in response to presence of the second enrichment information corresponding to the user device in the database.

  • Patent number: 11263262
    Abstract: Aspects described herein may relate to methods, systems, and apparatuses that process one or more tags associated with a dataset and index the dataset based on the processing of the one or more tags. Processing a tag may include, for example, tokenizing the tag, mapping or expanding abbreviations included within the tag, and otherwise mapping or expanding elements of the tag based on alphanumeric characteristics. Additionally, as part of processing the tag, a number of potential tags may be determined. An ontology may be searched to determine whether any of the potential tags are also found within the ontology. The dataset may be indexed into a searchable index based on any of the potential tags that are found within the ontology.

  • Patent number: 9990686
    Abstract: A method for generating a data-bearing image is implemented by an encoding system including a halftoning module and an encoding module that stores encoding rules associated with respective codes. In the method, the halftoning module converts a grayscale image into a halftone image having a plurality of image cells each consisting of a plurality of dots, at least one of which is a first-tone dot and each of the rest of which is a second-tone dot. Afterward, the encoding module generates a data-bearing halftone image encoded with at least one of the codes by maintaining or changing the number of the first-tone dots in one of the image cells based on one of the encoding rules associated with the at least one of the codes.

  • Patent number: 9544467
    Abstract: An encoding system converts a grayscale image into an original halftone image according to a predetermined threshold matrix, determines carrier cells from the original halftone image according to reference dot patterns having rotationally asymmetric first-tone patterns, converts the carrier cells into encoded cells according to to-be-embedded codes and rotational states of corresponding asymmetric first-tone patterns, and optimizes non-carrier cells and encoded cells using a direct binary search technique to visually approach the grayscale image.

  • Patent number: 6315307
    Abstract: A collapsible scooter has a frame plate secured on a head tube of the scooter, a strut having a lower end thereof pivotally connected to a foot board of the scooter and an upper end thereof pivotally connected to the frame plate. Opposite sides of the frame plate are symmetrically defined with two pivot slots, the upper end of the strut is pivotally connected with the frame plate and movable along the pivot slots between an upper position in which the scooter is fully collapsed and a lower position in which the head tube is uprightly extended. A retaining device is particularly provided in the scooter to prohibit the head tube from any inadvertent movement relative to the foot board, even when the head tube is subjected to excessive stress during riding on a rough road.
