  • Patent number: 12354361
    Abstract: A system for monitoring safety compliance comprises a plurality of cameras and a computing system. The plurality of cameras are configured to obtain data, and the data comprises multiple images associated with one or more objects. The computing system is configured to process the data to determine the safety compliance of the one or more objects associated with the multiple images based on implementing a first model trained for re-identification. The computing system is further configured to train the first model for re-identification, by determining a similarity loss and updating the first model based on the similarity loss.

  • Patent number: 12250330
    Abstract: A method for performing Building Information Modelling design collaboration via Confidentiality-Minded Framework using Interplanetary-File-System-Blockchain integrated network by a server is provided. The method includes: segregating one or more sensitive and non-sensitive BIM portions of a BIM object; uploading a target BIM component into an IPFS network to receive a target content identifier (CID) of the target BIM component from the IPFS network; if the target BIM component has one or more of the sensitive portions, encrypting the target CID to obtain a target encrypted CID (ECID), and adding the target ECID into a target blockchain ledger as a target transaction via a target smart contract; accessing the target transaction to download the target BIM component from the IPFS network; and performing a design coordination operation on the target BIM component, so as to distributing revised target BIM component to a receiver terminal.

  • Publication number: 20230294381
    Abstract: A composite thermoformed tableware and preparation method thereof. The preparation method involves a preheating step, a compositing step and a thermoforming step in sequence; the preheating step heats multilayer forming materials at a temperature of 35° C. to 150° C., the forming materials have one or at least two of paper, plastic and inorganic layer; the compositing step involves stacking the preheated forming materials to form a composite material; the thermoforming step involves heat-pressing the composite material at a temperature of 80° C. to 150° C. and a pressure of 0.05 MPa to 0.5 MPa to form a three-dimensional body. The tableware is thermoformed by multiple layers of the same material or different materials, so that the thickness and strength of the tableware are higher.

  • Patent number: 11686546
    Abstract: A firearm locking system that can lock a trigger by remote activation by an authorized user using a trigger lock that can block a trigger of a firearm from being pulled sufficiently to fire the firearm, The trigger lock can be advanced forward into the locked configuration and retracted into an unlocked configuration with the use of an actuator, such as a motor, Tamper-resistant features can be employed to prevent unauthorized users from disabling the firearm locking system. For example, when the trigger lock blocks the trigger, the trigger lock can also lock the upper receiver from being removed preventing access to the firearm locking system from the top of the firearm. The actuator or can be detachably connected to the trigger lock such that when the grip is removed, the actuator disconnects from the trigger lock causing the trigger lock to enter a jammed configuration.

  • Publication number: 20230095533
    Abstract: A system for pedestrian re-identification comprises multiple cameras and a computing system. The cameras are configured to obtain data. The data comprises multiple images associated with one or more objects. The computing system is configured to extract features for each of the multiple images, determine a descriptor for each of the multiple images, and identify one or more images among the multiple images associated with an object among the one or more objects based on the descriptors of the multiple images. A respective descriptor for a respective image comprises a first set of units representing all the extracted features in the respective image and a second set of units representing a subset of the extracted features in the respective image.

  • Patent number: 11415235
    Abstract: A hydrant valve with an internal automatic shut-off valve. The internal valve blocks communication between a piston chamber and a hydrant chamber when in a closed position. An upper valve opens the internal valve against its biasing force permitting the flow of fluid between the hydrant chamber and the piston chamber. The internal valve closes in response to a disconnection of the upper valve.
