A cationic electrodeposition coating composition may contain at least two or more different emulsions in a mixed state, in which one of the emulsions is an emulsion (A) of an amine-modified epoxy resin containing a primary amino group or a secondary amino group, and another one of the emulsions is an emulsion (B) of an epoxy compound not containing a primary amino group and a secondary amino group and containing two or more epoxy groups in one molecule. A method for producing said coating composition may include a step of mixing the emulsions (A) and (B). A coating method may be performed in conjunction with the producing method by immersing a metal object in said coating composition and then finishing the coating by drying.

A system and method are provided wherein, in at least one form, artificial intelligence is used to identify objects in a document to be considered for metallic rendering or printing on a substrate.

A system (IQE) for image processing and related method comprises an input interface (IN) for receiving a first image volume (V1) which is reconstructable from projection data (λ) which is acquirable by an X-ray detector of a tomographic imaging apparatus for a first region (EFOV) of an imaging domain (ER). During acquisition, an occluding object (OO) is located inside said first region, but the occluding object (OO) or parts thereof is located outside a second region (SFOV) of the imaging domain (ER) which is different from the first region (EFOV), and wherein said second region (SFOV) can comprise a region of interest to be imaged. An artifact corrector (AC) corrects image artifacts based on said first volume (V1) which can be caused by said occluding object (OO) in a second image volume (V2) which is reconstructable from said projection data (λ) of said second region (SFOV) in said domain (ER).

The application discloses a mechanical arm grabbing method in a cluttered scene based on a mixed gripper and belongs to the technical field of robot grabbing. The method comprises the following steps: acquiring a target scene image, predicting the pose and circumscribed cube of a non-metallic object by using a pose estimation model FFB6D, and predicting a segmentation mask of an object containing a metal part by using an instance segmentation model YOLO11n-seg. A candidate grabbing pose of a parallel gripper and an air pump suction disc is generated according to the upward surface distribution of the circumscribed cube, and a candidate grabbing pose of an electromagnet is generated according to the three-dimensional position of the segmentation mask. Finally, the grabbing pose is eliminated based on the visibility of a rendered image and collision detection, and the optimal pose and the corresponding end tool are selected to perform grabbing. The application overcomes the problems of low object visibility and poor applicability of a single gripper in a cluttered and stacked scene, and significantly improves the grabbing success rate in the state of multiple object scattering and stacking.

This utility model discloses an easy-to-install sensor for intelligent building monitoring, belonging to the field of sensor technology. It includes a sensor body with a sensing head and a back plate on its back side, as well as a connector. Through a designed mounting structure, movable blocks are set in grooves and slots. These, in conjunction with adjusting screws, allow for adjustment of the positions of the movable blocks and mounting plate. The mounting plate is connected to the movable blocks via pins, threaded posts, and other structures, allowing for rotational adjustment to better align the mounting holes with the screw holes at the mounting location, facilitating quick and easy installation of the entire sensor. Magnets are placed on the mounting plate, allowing the sensor to be magnetically attached to metal objects without the need for drilling, further improving installation flexibility and adaptability. An auxiliary fixing structure applies an elastic force to the connector, enhancing its stability.

Instrument that allows the retrieval of metallic foreign bodies lost in the disc space (Figure 1). This instrument has two jaws (Figure 2) which open like those of scissors but whose particularity is that one of the jaws is magnetized so that the metallic foreign body adheres to it (Figure 3), the second jaw then catches it by means of a conical clamping (Figure 4), which allows a capture on the spot of the foreign body while preventing it from escaping deep into the disc space. We propose a second configuration of the surgical instrument (Figure 6), which increases the functional clearance between the two jaws to allow for the retrieval of foreign bodies of varying thicknesses. This solution is equipped with three springs of different stiffnesses, positioned coaxially with the jaws' axis of rotation, with transverse displacement to accommodate different thicknesses of foreign body to be retrieved. The central spring maintains a minimal initial play, which gradually increases as the jaws close. Conversely, the two outer springs apply a clamping force that ensures the captured foreign object is immobilized. This instrument is very easy to use. With the jaws open, the instrument is inserted into the disc space parallel to the vertebral endplates. The foreign object will be attracted to the magnetic jaw. Once in place, and under fluoroscopic guidance, the surgeon closes the jaws of the forceps, allowing for safe retrieval of the foreign body. We propose that this instrument be included in the standard equipment of all spinal surgery operating rooms. Indeed, although rare, the loss of a metallic foreign body at the surgical site, particularly within the disc space (e.g., a broken instrument or scalpel blade), is potentially serious. The invented instrument represents a "life-saving tool" that helps to avoid further complications, including life-threatening situations.
