  • Publication number: 20250139726
    Abstract: Improved security checkpoint includes a security scanning system having multiple personal item intake locations, a security scanner, multiple personal item retrieval locations, and a plurality of computer-controlled vehicles for transporting personal items between the personal item intake locations, the security scanner, and the personal item retrieval locations. Personal items are placed into a tote by an individual, and the computer-controlled vehicles collect the totes containing the personal items, transport the tote to an available security scanner, deposit the tote at the security scanner, and then transport the tote either to a retrieval location or secondary screening location after the personal item has been screened.

  • Patent number: 12264497
    Abstract: A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

  • Publication number: 20250014200
    Abstract: Certain examples described herein relate to a mapping system. An example mapping system has a differentiable mapping engine to receive image data comprising a sequence of images captured using one or more camera devices of an object as it navigates an environment and a neural network scene representation comprising a neural network architecture trained to map input coordinate tensors indicating at least a point location in three-dimensional space to scene feature tensors having a dimensionality greater than the input tensors. The neural network scene representation is communicatively coupled to the differentiable mapping engine and the differentiable mapping engine is configured to use the neural network scene representation as a mapping of the environment during operation of the differentiable mapping engine.

  • Publication number: 20250014279
    Abstract: In described examples there is a method of matching a design model. In examples, a point cloud representation of a construction site is generated. The point cloud representation is generated using a positioning system that tracks a device such as a headset within the construction site. A building information model is obtained representing at least a portion of the construction site. One or more points in the point cloud representation are compared with the building information model to determine whether the construction site matches the building information model, wherein the point cloud representation is generated dynamically as the device navigates the construction site.

  • Patent number: 12188298
    Abstract: A door system includes a doorframe having opposing vertical jambs, a door pivotably coupled to the doorframe, a threshold extending between the opposing vertical jambs and providing an upper surface that defines a valley, and a dam removably mountable to the threshold at the valley. A valley seal interposes the dam and the threshold at the valley when the dam is mounted to the threshold and thereby generates a sealed interface between the dam and the threshold.
