Abstract: The invention concerns a shoe scanning system for a full-body scanners canning an individual before access to a restricted access area. The system comprises a detection unit (10) comprising: a detector for sensing a metal and/or unauthorized object located above a surface (111) onto which the individual can walk; a communication unit for transmitting a message to an indication unit for providing instructions to the individual and/or to an assistant; and a processing unit connected to the detector by a data link for receiving data and controlling the communication unit for sending a detection signal when the detector indicates a presence of a metal and/or unauthorized object. The detector comprises a short-range sensing element (122) and a long-range sensing element (123) for detecting a metal and/or unauthorized object up to a maximal distance (1231) greater than the maximal distance of the short-range sensing element.

Abstract: A method of monitoring metal pieces including generating, on a computing device, a 3D digital model of a metal piece to be produced by additive manufacturing; and identifying regions of interest in the model where defects are more likely to occur during manufacturing The regions of interest are identified using software to check the model according to specific design rules. N NDT sensors are either: selectively activated among a total of M NDT sensors, or mounted on a sensor supporting structure at specific locations along an axis. The N NDT sensors are selectively activated or mounted as a function of the regions of interest identified in the model to retrieve data on the properties of the quality of metal parts of the metal piece only for the corresponding regions of interest of the metal piece during its additive manufacturing. Also, a system is configured to carry out the method.

Abstract: The invention concerns a system (1) and a method for scanning a person (2) before access to a restricted access area (3), comprising a processing unit (14) and a metal detector (10, 70) for detecting metal in the shoes (20) or in a waist portion of the person walking on a surface (15). The processing unit controls an indication unit (12, 13) for: letting the person walk towards the restricted area if a first scan indicates the probability of the presence of metal lower than a first threshold; in case of a probability higher than the first threshold, prompting the person to carry out a second scan close to a mark (11) on the carpet; and prompting the user to remove his shoes or object if the first scan indicates a probability higher than a second threshold, or if the second scan indicates a probability higher than a third threshold.

Abstract: Disclosed herein is a method for monitoring a health status of one or of a plurality of bridges (10) under normal traffic condition.

Abstract: The invention concerns a method and a system (1) for detecting a threat in a shoe (21, 22) worn by an individual (2) accessing a restricted access area (50) through a security access point (51). The method comprises obtaining a first response provided by a first metal detector (11) by sensing a pair of shoes worn by the individual. The first response is compared with a signature signal representing a shoe comprising a threat or an object representing a threat so to indicate a critical pair of shoes. In such case, the method further comprises prompting the individual to place the critical pair of shoes at a predefined position to obtain a second response provided by the first or by a second metal detector (12, 13) by sensing one shoe of said critical pair of shoes. A potential threat is detected by comparing the second response with the signature signal.

Abstract: The invention relates to a rotatable inspection device (10) for inspection of the integrity of an axisymmetric portion (210) of parts (200), for example a threaded tube (200). The rotatable inspection device (10) includes a measuring unit (20) configured to be rotated about the symmetry axis of the axisymmetric portion (210). The measuring unit (20) comprises: i) a radially movable measuring structure (22) comprising a defect detection sensor (30), wherein said measuring structure (22) is configured to urge the defect detection sensor (30) against said portion (210) to be inspected; ii) an electronic device (43) for processing and transmitting the signal measured by the defect detection sensor (30) along said portion (210), and iii) a measuring unit support (50) supporting the radially movable measuring structure (22). The electronic device (43) is configured to wirelessly transmit the processed signal to a remote monitoring unit (300).

Abstract: The invention concerns a method for additive manufacturing a component by repetitively superposing and solidifying material layers according to a 3D model of the component. The method comprises the steps of scan, by means of an eddy current sensing unit (20), of a new solidified cross section (15) obtained by selectively solidifying a material layer so as to provide an integrity data (VMM) of a sensed portion (23). A difference between the sensed integrity data (VMM) and an expected integrity data (VEE) is then executed for detecting a manufacturing anomaly within this portion. The expected integrity data (VEE) is determined based on collected integrity data of a solid basic structure likely matching or being identical to a geometrical structure (41) obtained from the 3D model (40) of a portion corresponding to said sensed portion (23), said solid basic structure being manufactured or simulated according to another 3D model.
