An HV, EHV or MV power cable (10) comprising at least one insulated conductive core, a metallic screen (14) surrounding the at least one insulated conductive core (12), a sheath (16) surrounding the metallic screen (14), and at least one optical fiber element (40). The optical fiber element(s) (40) is/are embedded in and surrounded by the sheath (16) in a position that is radially outward from and spaced from the metallic screen (14), helically or SZ stranded around the metallic screen (14). The optical fiber element(s) is/are dielectric and comprise(s) at least one tube surrounding one or more optical fibers, and an element jacket surrounding the tube(s). A process for manufacturing the HV, EHV or MV power cable.

An optical fiber cable (10) comprising an optical core (12) comprising at least one tube (14) containing at least one optical fiber (16). At least one protecting layer (42, 44) surrounding the optical core (12) is made of an elastomeric polymer material. The elastomeric polymer material has a density of from 1.2 to 1.4 g/cm<3>. The elastomeric polymer material has Shore A hardness of at most 70.

A system receives 2D depth-map images of an empty conveyor belt. The system generates a training set of labelled 2D depth-map images based on the 2D depth-map images. The system trains or fine-tunes a neural network using the training set to form trained parameters that cause the neural network to detect items on the conveyor belt using 2D depth-map images of the items on the conveyor belt. In an alternative embodiment, a pre-trained neural network is configured to select feature map channels generated from 2D depth-map images of items on a conveyor belt. The selected channels are resized and combined to provide relevant data for generating a segmentation mask based of the items using a binarization threshold that is automatically determined. The system may include a pretrained image segmentation model that generates at least one instance segmentation mask from the 2D depth-map images.

Systems and methods detect scan avoidance behaviors at a self-service point-of-sale (POS) terminal. The system includes a camera positioned to capture video images of an operational area of the POS terminal and a computer that determines when movement of an item by a customer operating the POS terminal indicates scan avoidance. The computer receives video images from the camera, preprocesses frames of the video images to suppress background and to track the movement of the item from a pickup area of the POS terminal, through a scan area of a scanner of the POS terminal, and to a bagging area of the POS terminal. The system may also include a 3D sensor for detecting depth data that is used to improve hand-item contact.

A system and method to evaluate transactions executed at self-server point-of-sale (POS) terminals located at retail stores with improved ability to identify potential shoplifting incidents. The service determines most stolen K items (MSKI) from a transaction history and shopping theft data of the retail store, where K is an integer value greater than one. The service generates a set of not stolen K items (NSKI) based on market basket analysis of the transaction history. The service defines suspect transaction classes based on the MSKI and the NSKI and generates an alert for a current transaction at the retail store when items in the current transaction match one of the suspect transaction classes.

A silicon steel sheet stacking structure includes a main silicon steel lamination, a blocking silicon steel sheet, and a riveting blocking portion. The main silicon steel lamination includes silicon steel sheets stacking in a first direction. Each of the silicon steel sheets has at least one through hole. The blocking silicon steel sheet is disposed on the main silicon steel lamination. The blocking silicon steel sheet has at least one through hole. The riveting blocking portion is extended from the blocking silicon steel sheet and is raised above a surface of the blocking silicon steel sheet. The riveting blocking portion is configured to be compressed and generate a deformation, such that the riveting blocking portion pushes at least one magnet located in the at least one accommodating space to abut the at least one magnet against an inner surface of the at least one through hole.

An uninterruptible power supply system includes a bidirectional AC-DC converter, a resonant converter, an automatic voltage regulation circuit and a control unit. When an AC input voltage is out of a predetermined voltage range and within a voltage regulation range, the automatic voltage regulation circuit, the resonant converter and the bidirectional AC-DC converter generate an AC supplementary voltage at an output terminal based on the AC input voltage and generate an AC output voltage based on the AC input voltage and the AC supplementary voltage, so that the AC output voltage is within the predetermined voltage range. When the AC input voltage is out of the voltage regulation range, the resonant converter and the bidirectional AC-DC converter generate the AC output voltage at the output terminal based on discharge voltage of a battery, so that the AC output voltage is within the predetermined range.
