Description

Technical Field

[0001] The present invention relates to a screening device and a method for screening people.

Background Art

[0002] Screening people can be carried out for safety reasons. Screening people can, for example, check whether a person is carrying any item that may remind of dangerous items such as knives, scissors, or other metal objects, weapons such as firearms, explosives, etc.

[0003] Screening people can be carried out at various locations, for example, at the entrance of a building, at the entrance of a theater, at a railway station, at an airport, etc.

[0004] Screening may involve a plurality of people to be screened. On the one hand, delays and waiting can be avoided, but on the other hand, it may be necessary to minimize the available resources (security personnel for screening, screening devices, the area of the building floor space, etc.). Furthermore, the risk of incorrect screening results must be minimized.

[0005] When screening people, metal detection gates have conventionally been used. In more recent developments, radio scanners such as millimeter wave scanners or terahertz scanners are used to scan people for objects that may be associated with safety risks.

[0006] In the case of these types of scanners, people are required to enter a cubicle that is at least partially surrounded by walls. The cubicle may be closed by a door or a slider, for example, to prevent passengers from passing through before being permitted. If the scanning process identifies a risk, for example, that an item is being carried by a person, or if a defect in part of the scan is identified, a warning that needs to be lifted is generated, which may cause a delay.

Summary of the Invention

[0007] The present invention aims to avoid or shorten delays in the selection and screening process for individuals. [Means for solving the problem]

[0008] According to an aspect of the present invention, a selection and screening device for selecting and screening people, - A private room with walls that at least partially enclose the interior space, - A sensor on at least a portion of the surface of a wall facing the interior space, configured to detect a person present in the interior space, - A projector that projects images into an internal space so that they can be seen by people, - A control device connected to a sensor and a projector, It is configured to activate sensors to detect people present in the interior space. It is configured to drive a projector to project commands associated with the operation of a sensor onto a person. Control devices and A sorting and inspection device equipped with the following is provided.

[0009] The walls surrounding the interior space can form individual rooms in which people are screened. Each room may have one or two openings for a person to enter and / or exit, such as an entrance opening on the entrance side and an exit opening on the exit side, and these openings may be closable by doors, sliders, etc. Sensors on at least a portion of the surface of the walls facing the interior space may be of any type, such as radio wave scanners, such as millimeter-wave scanners or terahertz scanners. The sensors may be stationary relative to the wall or movable on the wall surface, such as being able to rotate around a person to scan them from an inscribed angle.

[0010] A projector can project images into an internal space, and can be any type of projector, such as being positioned on the ceiling of a private room, above the space in a private room where a person appears for screening. For example, a projector can project images onto the walls of a private room. Another example is that a projector can project images into space, for example, in a holographic manner. For example, a projector may be equipped with a 3D laser projector or other 3D projector to project images into space.

[0011] The control device may comprise any suitable control device, such as a microcontroller, microprocessor, or PLC (Programmable Logic Control Device), which is provided with appropriate program instructions for carrying out the steps described.

[0012] The control device drives sensors to detect people present in the internal space. Sensor data provided by the sensors can be processed locally or sent to a sensor data processing device (e.g., local or remote). For example, sensor data formed by radio signals can be processed to derive an image. The image can be sent to an evaluation data processing device, which can evaluate the image to identify hazards, such as objects carried by people (knives, weapons, etc.). The evaluation data processing device can be self-learning and may include a neural network or other intelligent programming architecture that establishes whether objects that may evoke hazards can be identified in the image. The self-learning evaluation data processing device can be trained from training data, for example, that includes images in which potentially hazardous objects have been identified by human workers. The sensor data processing device and evaluation data processing device may be included in the control device or may be formed separately, such as a remote device.

[0013] To ensure that people comply with the selection process, the control device drives a projector to project commands associated with the sensor's operation onto the person.

[0014] This provides a person with instructions on what to do to ensure they comply with the screening process. For example, a person may be asked to empty their pockets and place items such as hand luggage, keys, wallet, coat, vest, etc., on a tray. Another example is that a person may be asked to stand in a designated place in the room and / or to maintain a designated posture, such as extending their arms overhead. Yet another example is that a person may be informed that the scan is complete and instructed to leave the room.

[0015] As a result, delays can be prevented, such as those that may be recalled in prior art solutions. In prior art solutions, a worker may enter a room, and the person may be prompted by the worker to leave the room or given instructions on how to proceed. This can result in delays when the person may be initially asked to leave the room, when instructions may be given, or when they may be asked to remove an item from their pocket and then be ordered to re-enter the room for repeated sorting and inspection. This delay may even be greater than initiating conventional detection, and for safety reasons, it may be avoided for a worker to enter the confined space of the room where the person being sorted and inspected is located, and therefore, asking the person (who may be psychologically focused on following written instructions in the room, may be under stress, etc.) to pay attention to a worker outside the room may require asking them to open a door or slider surrounding the room and to ask the person to leave the room.

[0016] Furthermore, when an image is projected into a private room, that is, into the interior space of the private room, the display panel in the private room may be omitted. As a result, interference from display panels with sensors can be avoided. Various causes of interference can be avoided. On the one hand, the display panel itself, which forms a physical structure, may interfere with radio waves emitted by sensors, thereby interfering with human scanning. On the other hand, display panels such as LCD panels or LED panels may emit high-frequency signals themselves, for example, from drive signals in the panel associated with driving the pixels of the display device. Such digital data processing and data communication in the display panel may result in the emission of radio frequency signals that can interfere with human detection, specifically when radio waves are used to detect people.

[0017] In this embodiment, the control device further includes: - It is configured to derive the location of an object relative to a person from sensor data. - Configured to control a projector to display the location of an object in relation to a person.

[0018] A control device can determine the location of an object when it detects it during scanning and related processing. Therefore, the control device can drive a projector to display the object's location. The person is then instructed to retrieve the object, for example, by placing it in a container or tray, thereby displaying the object's location to the person, clearly indicating what they are expected to do. The object could be any safety-related object, such as a metal object, weapon, explosive, or liquid. Furthermore, the object could be any object that a person might forget to retrieve, such as a wallet, keys, or smartphone, which could, for example, interfere with scanning. Once the object's location is indicated to the person, they may be able to retrieve the object as instructed without further actual worker intervention.

[0019] To visually inform a person of the location where an object has been found, an artificial reality mirror image can be generated that displays a mirror image of the person including the object. For this purpose, the sensor further comprises a camera oriented to a desired location of the person in internal space, the camera is connected to a control device to transmit camera image data to a control device, the control device is configured to generate a mirror image of the person from the camera image data, to create a fused image of the person by fusing the object at the derived location into the mirror image of the person, and to control a projector to display the fused image of the person. Thus, a mirror image of the person in which the location of the object has been fusing can be presented to the person. The object may be indicated by an emoji indicating the type of object detected, such as an emoji of a key, wallet, or telephone, or by a shape corresponding to the shape of the object sensed by the sensor.

[0020] In this embodiment, the sorting and screening device further comprises a camera configured to generate image data, a gesture sensor configured to sense human gestures and generate gesture data, and a motion sensor configured to record human movement and generate motion data. The control device is configured to perform a risk assessment from a combination of sensor data, camera image data, gesture data, and motion data, and to generate a warning message based on the risk assessment.

[0021] As a result, a person's behavior, such as deviations from typical behavior, may be detected and evaluated.

[0022] The control device is configured to perform hazard assessments using a self-learning system, which is trained using a training dataset that additionally includes worker evaluations based on sensor data, camera image data, gesture data, and motion data. This allows experienced workers to train the self-learning system.

[0023] In an embodiment, the screening device further includes a footwear sensor on at least a part of the surface of the floor of the private room, the footwear sensor being configured to sense the footwear of a person present in the internal space. The footwear sensor may be configured to sense the position of the footwear, the presence of metal, the presence of liquid, or an item or substance that potentially evokes danger. The control device may further be configured to operate the footwear sensor to sense the person's footwear, or may be configured to drive a projector to project an instruction associated with the operation of the footwear sensor onto the person. The footwear sensor may be formed, for example, by a micrometer of a millimeter-wave scanner provided with an antenna inside or on the surface of the floor of the internal space. The footwear sensor can use, for example, quadrupole resonance. Quadrupole resonance, also identified as nuclear quadrupole resonance spectroscopy or NQR, may be understood as a chemical analysis technique regarding nuclear magnetic resonance (NMR). Different from NMR, the NQR transition of the atomic nucleus can be detected without a magnetic field. For this reason, NQR spectroscopy is referred to as "zero-field NMR". The NQR resonance is mediated by the interaction of the quadrupole moment of the nuclear charge distribution with the electric field gradient (EFG). Different from NMR, NQR is applicable only to solids and not to liquids because the quadrupole moment is averaged in liquids. Since the EFG in the atomic nucleus in a given substance is mainly determined by the valence electrons associated with specific bonds with other nearby atomic nuclei, the NQR frequency at which the transition occurs is unique for a given substance. The specific NQR frequency in a compound or crystal is proportional to the product of the nuclear quadrupole moment, the nature of the atomic nucleus, and the EFG near the atomic nucleus. This product is named the nuclear quadrupole coupling constant for a given isotope in the material and can be found in a table of known NQR transitions. In NMR, a phenomenon that is similar but not identical is the coupling constant, which is also the result of the internuclear interaction between atomic nuclei in the inspection target.

[0024] The footwear sensor can enable the screening of a person while the person is wearing their own footwear (e.g., shoes, sandals). The measurement data obtained by the footwear sensor can be processed either by the footwear sensor itself (e.g., by its processing device or image processing device) or by a control device. When the scanning of the footwear by the footwear sensor and the associated processing of the measurement data results in the detection of an object associated with danger, the control device can drive a projector to project an instruction to the person to, for example, remove their shoes and present them for scanning by the carry-on scanning device of the screening device. As a result, when the measurement by the footwear sensor and the associated processing of the measurement data indicate a potential danger, the person can be instructed to remove their footwear. When the screening device is equipped with a carry-on scanning device, the person can be instructed to present their footwear to the carry-on scanning device, for example, in a carry-on feeding tray. Thus, the screening process can proceed to a subsequent step, namely, the scanning of the footwear by a carry-on scanning device or the like, without the need for immediate intervention or action by an operator.

[0025] In an embodiment, to provide assistance to the operator to the person, the control device is - configured to establish a connection to an operator console, - configured to output an instruction to the operator at the operator console for communicating to the person, - configured to control a projector to display an image of the operator (e.g., a video image of the operator) at the operator console.

[0026] Because worker assistance is provided via displays, a person in a private room may receive (e.g., audiovisual) instructions from the worker. The person can communicate with the worker using the camera and microphone included in the safety device, i.e., within the private room, thus communicating with the worker without the person having to leave the private room. On the one hand, assistance can be quickly made available because the worker does not have to walk into the private room, and on the other hand, the worker can provide assistance and / or manage multiple safety devices from the worker console, thereby potentially increasing efficiency.

[0027] In this embodiment, the control device is - It is configured to derive the location of an object relative to a person from sensor data. - Configured to transmit the location of an object in relation to a person to the worker console. - It is configured to send a command to the worker console requesting the worker to describe the location of an object to a person.

[0028] Therefore, the worker can be assisted in remotely assessing the cause of non-compliance, such as an object being carried by a person. The location of the object is sent to the worker console and displayed there. This allows the worker to explain to a person where the object was found during the scan and what needs to be done. To assist the remote worker, the control device can send a video stream to the worker console showing the entire process, from entering the room to the situation triggering the call for a remote worker to assist the person.

[0029] To provide that worker assistance may be required in various situations, in the embodiment, the control device is configured to output a command to the worker when a criterion is met, and the criterion is, - When a person initiates a worker contact request (for example, when a person does not know what to do, is confused, is facing an error message, is panicking, etc.) - The control device establishes that a pre-set selection review time has elapsed (for example, several attempts have been carried out unsuccessfully), - The control device establishes that the existence of an object has been established. It includes at least one of the following.

[0030] In the embodiment, the sensor comprises a radio scanner with a radio antenna array, the radio antenna array covering at least a portion of the surface of the wall behind the projected image. The projected image can be made so as not to interfere with the radio wave transmission from the antenna array, thus avoiding interference or weakening of the radio waves from the antennas behind the projected image, thereby enabling scanning of a person using all antennas, and potentially avoiding blind spots in scanning a person by avoiding the "shadow" effect of a display panel interposed between one or more of the antennas and the person.

[0031] In the embodiment, the projector is configured to project a two-dimensional image onto the wall of a private room, or to project a three-dimensional image into the interior space.

[0032] In the embodiment, the sorting and inspection device further comprises an object deposit tray, and the command includes a command to deposit an object into the object deposit tray. The tray may be stationary for a person to collect the deposited object after scanning, or it may be transported by a conveyor to, for example, a baggage sorting and inspection system, as will be described in more detail later. If baggage inspection techniques that require shielding from people, such as X-ray inspection, are used, the baggage may be transported away from the inside of the compartment. Otherwise, inspection techniques such as infrared or video may be applied to the baggage.

[0033] In this embodiment, the sorting and inspection device further comprises a baggage sorting and inspection device and a conveyor for transporting baggage from a compartment to the baggage sorting and inspection device, and the control device is configured to drive the conveyor to transport baggage deposited in an object deposit tray to the baggage sorting and inspection device, to drive the baggage sorting and inspection device to sort and inspect the baggage, and to drive the conveyor to transport the baggage back to the compartment.

[0034] In the embodiment, the sorting and screening device further comprises an identification device, and the control device is configured to identify a person using identification data from the identification device and to associate the deposit tray with the identified person. Thus, when a tray holding an object is transported away by a conveyor, the association of the tray with a person can enable the corresponding person to transport the tray to a retrieval station where they have identified themselves. The identification device may include a camera, a passport scanner, a boarding pass scanner, and the like. Identification may be performed using biometric data, such as an image of a person's face or iris.

[0035] In the embodiment, the control device is configured to drive a display device to provide a person with instructions to follow a predetermined sorting and inspection sequence. This allows even a person unfamiliar with the procedure to perform an effective sorting and inspection. The sorting and inspection process may include, for example, the steps of a person identifying themselves at an identification station, a person removing their coat or jacket, a person placing their coat or jacket on a tray, a person emptying their pockets and depositing items on a tray, a person taking a predetermined position (e.g., marked on the floor or displayed by a projector), a person extending their arms, a person being scanned by a sensor, a person being informed that the scan was successful (e.g., by a message projected by a projector), and a person being prompted to leave the room.

[0036] The sensor further includes a camera, and the control device is configured to process images from the camera and derive the progress of a person's screening process from these images, compare the derived progress of the screening process with a predetermined screening sequence, and derive commands to be provided to the person from the comparison of the derived progress with the predetermined screening sequence. Image processing and self-learning systems may be used to evaluate the progress. The self-learning system may first be trained using images (such as video or still images) and associated worker input.

[0037] In this embodiment, the sorting and inspection device is - A baggage sorting and inspection device configured to scan baggage checked in by a person, further comprising a primary scanner and an X-ray diffraction scanner, The control device is - The baggage is scanned by a primary scanner to generate primary scanner output data associated with the baggage scan. - Determine areas of interest in the baggage from the primary scanner output data. - The X-ray diffraction scanner is operated to scan areas of interest on the baggage and generate X-ray diffraction output data associated with the scanning of the baggage by the X-ray diffraction scanner. - Process primary scanner output data and X-ray diffraction output data to determine whether a warning signal is generated, and, - If generated, output a warning signal. The baggage sorting and inspection device is configured to operate in this manner.

[0038] The primary scanner may include an X-ray scanner, such as a CT (computed tomography) scanner. The primary scanner can identify potentially relevant objects, such as liquids that may require further examination. If potentially relevant objects are identified in the output data (image data) of the primary scanner, the area of ​​interest may be marked on the baggage image, and the area of ​​interest may cover or coincide with the potentially relevant object. Thus, the area of ​​interest may relate to a part of the baggage or to the baggage itself. Therefore, an X-ray diffraction scanner may be operated to scan the area of ​​interest. When using X-ray diffraction scanning, the material of the potentially relevant object may be determined based on the diffraction pattern of X-rays emitted into the area of ​​interest. In the case of potentially hazardous materials, the control device may generate a warning signal and output it, for example, to the operator console, so that the operator can take appropriate action.

[0039] In this embodiment, the sorting and inspection device is A first identification station configured to require a person to present a token, A baggage drop-off station configured to receive baggage checked in by a person, wherein the first identification station is associated with the baggage drop-off station, and the baggage drop-off station A baggage sorting and inspection system configured to sort and inspect baggage, A baggage retrieval station downstream of a sorting and screening system, configured to collect baggage checked in by people, A second identification station associated with a baggage collection station, wherein the sorting and screening device forms a pathway for people from the baggage drop-off station to the baggage collection station, A baggage handling system configured to transport baggage from a baggage drop-off station to a baggage collection station via a baggage sorting and inspection device, and Furthermore, The control device further, It is configured to read a token presented by a person at the first identification station, The presented token is configured to be associated with baggage checked in by a person at the baggage drop-off station. When a person is screened by a screening device, a second identification station at the collection station is configured to read the token presented by the person. It is configured to control the baggage handling system to transport baggage associated with a token to a baggage collection station.

[0040] The first identification station may request any appropriate token, such as a passport, driver's license or other identification document, boarding pass, or airline ticket. In embodiments, the token may include biometric data such as facial recognition or iris scanning.

[0041] The baggage drop-off station receives baggage checked in by a person, and the first identification station is associated with the baggage drop-off station so as to associate the baggage as checked in by a person. The baggage may be checked in on a tray provided with identification such as RF identification or radio frequency identification so as to associate the baggage tray with a person.

[0042] Next, the baggage may be transported to a baggage sorting and inspection system for sorting and inspection.

[0043] Next, the person proceeds to the screening device as disclosed in this document.

[0044] A baggage retrieval station is set up downstream of the baggage sorting and inspection system so that baggage checked in by people can be retrieved by people.

[0045] A second identification station is provided and associated with the baggage collection station to identify which baggage, or tray, should be returned to the person.

[0046] The sorting and screening device forms a pathway for people from the baggage drop-off station to the baggage collection station, and only those who have been sorted and screened by the sorting and screening device can reach the collection station.

[0047] The baggage handling system transports baggage from a baggage drop-off station to a baggage collection station via a baggage sorting and screening device. After the baggage has been sorted and screened by the sorting and screening device, the person can identify the baggage as a second identification station, which then directs the baggage handling system to transport the baggage associated with the token to the baggage collection station for human collection.

[0048] The first identification device, the second identification device, the baggage deposit station, the baggage sorting and inspection system, the baggage transport system, and the baggage retrieval station may be located outside the individual compartments of the sorting and inspection device.

[0049] In this embodiment, the sorting and inspection device is Equipped with multiple baggage collection stations, The control device is configured to designate one of several baggage collection stations as a token, to control the baggage handling system to transport the baggage associated with the token to the designated one of several baggage collection stations, and to output instructions to a person who presents the token and passes through a sorting and screening device to receive the baggage associated with the token at the designated one of several baggage collection stations.

[0050] The sorting and screening device may further comprise multiple baggage deposit stations and associated first identification stations to further increase processing capacity. Thus, a person can be directed to an available empty deposit station and associated first identification station, then proceed to be sorted and screened by the sorting and screening device, and subsequently retrieve their baggage at one of the retrieval stations. In an embodiment, a person voluntarily proceeds to an empty retrieval station for identification, and subsequently, the corresponding baggage is transported to the retrieval station. Alternatively, a person may be instructed, by display or other means, to proceed to one of the retrieval stations. When multiple retrieval stations are used and multiple deposit stations are used optionally, the individual compartments of the person sorting and screening device and the baggage sorting and screening device can be used with optimal efficiency, thereby achieving the maximum flow of people and baggage per compartment of the sorting and screening device for each baggage sorting and screening device.

[0051] In the embodiment, the sorting and screening device further comprises an object deposit tray, and the control device is configured to control the baggage handling system to transport the objects deposited in the object deposit tray to one of a set of designated baggage collection stations. Thus, the sorting and screening device may further comprise an identification device for scanning tokens. Thus, the deposit tray can be associated with an identified person. Therefore, if the tray holding the objects is transported away by a conveyor, the association of the tray with a person can enable the corresponding person to transport the tray to a collection station where they have identified themselves.

[0052] According to another aspect of the present invention, the present invention comprises a baggage deposit station, a baggage retrieval station, a first baggage sorting and inspection device, a second baggage sorting and inspection device, and a baggage transport system for transporting baggage from the baggage deposit station to either the first baggage sorting and inspection device or the second baggage sorting and inspection device, and from either the first baggage sorting and inspection device or the second baggage sorting and inspection device to the baggage retrieval station, wherein the transport system comprises a shielded baggage transport path extending between the first baggage sorting and inspection device and the second baggage sorting and inspection device, and the baggage deposit station is the A sorting and inspection device is provided, in which baggage is loaded onto a shielded baggage transport path via a loading port having a transport direction perpendicular to the loading transport direction between the first baggage sorting and inspection device and the second baggage sorting and inspection device, and the shielded baggage transport path is discharged to a baggage collection station via a discharge port having a discharge transport direction perpendicular to the transport direction between the first baggage sorting and inspection device and the second baggage sorting and inspection device, and radiation shields configured to shield radiation generated by the first baggage sorting and inspection device and the second baggage sorting and inspection device are placed at the loading port and the discharge port.

[0053] The baggage sorting and inspection device may use X-ray radiation to inspect baggage. For safety reasons, the X-ray radiation is shielded from people. Shielding flaps are used at both the entrance and exit of the baggage sorting and inspection device. To provide shielding, even when a subsequent tray is being transported to the baggage sorting and inspection device, each preceding tray is transported out of the baggage sorting and inspection device, and multiple shielding flaps are used, for example, three flaps at each opening. When a baggage-carrying tray is about to pass through the shielding flaps, the contents of the baggage may be swept out of the tray by the flaps. Furthermore, the flaps may stop the tray, for example, if the tray contains lightweight baggage, or if bulky items in the tray are stopped by the flaps.

[0054] A shielded transport path between baggage sorting and inspection devices may allow for the omission of shielding flaps in the baggage sorting and inspection devices, thereby mitigating the problems associated with flaps in the prior art. Radiation shielding, such as a lead curtain, may be provided at the loading or unloading port to prevent further leakage of radiation.

[0055] The sorting and inspection device according to this embodiment may be included in the sorting and inspection device described above, but it may also be provided as a standalone device.

[0056] The radiation shielding material may be a lead curtain, and the shielding flaps in the first baggage sorting and inspection device and the second baggage sorting and inspection device may be omitted.

[0057] To provide further shielding at the loading and unloading ports, the loading port is provided with a loading port shield extending along the loading direction, and the unloading port is provided with an unloading port shield extending along the unloading direction.

[0058] To provide load balancing for the sorting and inspection devices, that is, to distribute trays in a balanced manner across the first and second sorting and inspection devices, the first and second baggage sorting and inspection devices can be bidirectional, and the shielded baggage transport path can be bidirectional, so that baggage can be served to either of the sorting and inspection devices.

[0059] According to a further aspect of the present invention, a method for operating a sorting and inspection system equipped with a sorting and inspection device according to the present invention, The sorting and inspection device is further configured to operate at at least two different detection rates. - A step to determine the detection rate of the screening system, which is the required detection rate for the screening system, - A step of selecting one of the detection rates of the sorting and inspection device in order to match the detection rate of the sorting and inspection system, - A step of sending a command to the control device of the sorting and inspection device in order to operate at a detection rate selected to match the detection rate of the sorting and inspection system. A method including this is provided.

[0060] The detection rate of a screening system defines the proportion of people in whom a safety hazard is detected. The rate may be defined, for example, as the overall detection rate of people wearing a specified hazardous material within a given (test) group. Alternatively, the rate may be defined as a rate for each type of hazard, such as the proportion of explosives or the proportion of weapons.

[0061] The screening system may comprise screening devices supplemented by other screening equipment and / or procedures. For example, the screening system may further comprise other detection devices such as cameras and radar, and / or a hazard profile computer device for assigning a hazard profile to each person. The hazard profile computer device may utilize artificial intelligence, for example, and may be provided with various data about the person, such as age, occupation, camera image data, and the person's past safety screening results.

[0062] Screening devices may be set to different detection rates. On the one hand, a higher detection rate can provide a higher rate of detecting hazards. On the other hand, a higher detection rate may provide a higher rate of false alarms or result in additional screening by, for example, security personnel, which reduces the processing capacity of the screening device, for example, in terms of the number of people per unit time. From an efficiency and cost standpoint, the intention is to balance detection rate and efficiency in order to meet the overall detection rate required by the system while keeping efficiency at the highest possible level.

[0063] Therefore, the sorting and screening devices may be set to different detection rates. To this end, the control device may change detection thresholds, such as setting warning thresholds, thresholds that determine when secondary sorting and screening is performed, or thresholds that determine what size / type of object is removed from a person's pocket. Such thresholds may be related to the detection rate in terms of the circumstances under which the threshold may be determined to proceed to further verification, warning, etc. Therefore, different detection rates of sorting and screening devices may be implemented by different detection thresholds, etc. One of the detection rates of the sorting and screening device may be selected. The detection rate of the sorting and screening device, combined with the detection rates of further equipment and procedures in the sorting and screening system, results in the overall detection rate of the sorting and screening system in which the sorting and screening device is included.

[0064] The detection rate of the screening device determines the detection rate of safety hazards detected in people, luggage, and / or footwear. For example, the warning threshold and / or secondary detection threshold may be modified.

[0065] In this document, the terms scanning, sorting, and sensing may refer to the same thing and are therefore interchangeable. Similarly, the terms person and passenger may both refer to a person and are therefore interchangeable if a person is a passenger. Likewise, terms such as object and item may refer to the same thing and are therefore interchangeable.

[0069] background Self-service is becoming a normal feature of more and more activities in our daily lives, and the trend toward self-service is more evident in travel than anywhere else. Today, travelers research and plan their vacations and book their own flights, hotels, transportation, restaurants, and activities. Upon arriving at the airport, travelers can tag their own checked baggage and print their boarding passes.

[0070] Similarly, aircraft security screening can be made more passenger-centric, allowing travelers to manage their own journey through checkpoints. There is also a strong business case for government, airport, and airline stakeholders to promote the use of self-service solutions and extend self-service to screening to drive productivity. These efficiencies in capital investment, along with the reduced staff requirements resulting from passenger risk segmentation and risk-based dynamic screening, increase flexibility in airport checkpoint design options, automation of detection and warning disengagement capabilities, and the integration of new and advanced technologies.

[0071] Therefore, the development here aims to ensure that the efficient design of a self-service passenger security environment provides a positive passenger-centric experience for a large number of diverse, multilingual, and multicultural travelers, while also meeting stringent screening requirements, i.e., ensuring safety outcomes.

[0072] Figure 1 depicts a perspective view of a screening device SD (also shown as a passenger self-screening device). The screening device comprises a private room CAB surrounded by walls WA that form an internal space INT into which a person PER enters through a door, which in this case is a sliding door SD.

[0073] technical concept The proposed concept can combine an intuitive human-machine interface, passenger data, and state-of-the-art physical screening technology to create a concept that may be applicable to all types of passengers and threat levels.

[0074] The selection process is explained below.

[0075] 1. Passenger arrival Passengers arrive at the checkpoint with their carry-on baggage. Two-way signage directs passengers to an available Passenger Self-Screening Device (SD). Passengers present identification (tokens such as passport, boarding pass, facial image, or other biometric information) to the reader. The reader verifies the passenger's identity and assigns a risk score to the passenger from Secure Flight data and other relevant sources. Once identity and flight information are verified, the reader / user interface instructs the passenger that clearance for screening is granted and the entrance door to the Passenger Self-Screening Device compartment opens.

[0076] Design and access control of passenger self-selection screening devices • Single-point passenger self-service sorting and screening device. • Modular design that can be integrated into a group of passenger self-screening devices. • It occupies the smallest amount of space. • A hardware sorting and inspection system for standard component bays. • High processing power.

[0077] Graphical user interface (GUI) for passenger interfaces • The user-friendly passenger GUI and screening workflow "Wizard" enables self-screening of accessible possessions and individuals. A screen displaying passenger process "wizard" instructions regarding the voluntary abandonment of threatening objects identified by the X-ray or human screening (OPS) automated target recognition (ATR) algorithm and rescanning to minimize ATR false alarms. • Multimodality TSO touchscreen (or contactless interface) workstation for process monitoring and alert decision-making.

[0078] Passenger data risk processing and future biometric interfaces • A fully enabled and built-in multi-cloud architecture featuring a robust API gateway with established services. • Real-time KTN verification service through a digital identity and identity verification app that incorporates facial matching software for biometric proof.

[0079] 2. Preparation for passenger self-selection screening Passengers move to a private CAB (Computer Absence Box) of a Passenger Self-Service Screening Device (SD), which is designed to be comfortable, spacious, and minimize anxiety or claustrophobia. The Passenger Self-Screening Device incorporates video (using a video camera) and associated analytics to monitor the passenger, informing them that the device is engaging them and identifying abnormal behavior. Two-way screens in the Self-Screening Device communicate the screening and rejection process to the passenger. Video with audio and written instructions provides commands. To this end, a projector is mounted, for example, on the ceiling of the private room, and projects video images PRO onto the walls of the private room, as depicted in Figure 2. Figure 2 schematically depicts the antenna ANT of a millimeter-wave scanning system that forms part of the sensor for scanning people.

[0080] Video System • An IP camera-based system including multiple cameras for multiple viewpoints to cover all passenger activities within the passenger self-screening device.

[0081] 3. Selection and screening of individuals Upon entering the passenger self-sorting screening device, the screening of the person begins. Passenger abandonment requirements are first determined by the video analysis system (e.g., coat, jacket), and the passenger interface screen communicates the abandonment order. Additional abandonment orders are communicated to guide the passenger to retrieve and place any other items that are normally abandoned by a person (e.g., phone, keys) in the belongings sorting screening system. The DRW drawer may be opened by the control device to form a baggage tray into which luggage (including phone, keys, etc.) can be checked. The passenger is then signaled by the video system to assume a scanning position. The optimal position of the passenger's feet on the floor FRL is also communicated to ensure that the footwear sorting screening system FWS can operate effectively. The passenger self-sorting screening device communicates instructions to the passenger when abandonment and scanning are complete. The passenger self-sorting screening device then instructs the passenger to place their belongings into the baggage drawer.

[0082] Voxel radar millimeter-wave body imaging during motion • The passenger self-screening device screens and screens passengers throughout the entire process. • Utilize optimized lighting and integrate scan data to avoid blind spots.

[0083] Figures 4A and 4B show an internal concept of the passenger self-selection screening device, illustrating possible locations for the sensor antenna ANT. Figures 4A and 4B: Inside the passenger self-selection device showing the passenger selection and screening system.

[0084] The control device may be configured to operate a footwear sensor to detect a person's footwear, and may also be configured to drive a projector to project commands associated with the operation of the footwear sensor onto the person.

[0085] The control device can control the footwear sensors to begin scanning a person's footwear once the person enters the passenger self-screening device's private room (i.e., internal space). For example, if the measurement by the footwear sensors, such as NQR measurement, takes longer than scanning the person, such as by mm wave measurement, the control device can control the footwear sensors to begin sensing while the passenger is still preparing for scanning, for example, by placing belongings on a tray and / or reading instructions provided via a projector.

[0086] 4. Dispelling warnings to people To assist passengers in deactivating personal warnings themselves, the system's passenger interface directs the passenger to the location of the warning and instructs the passenger PER to remove the warning item or shoes and place them in the baggage (possessions) sorting machine. A projector projects an artificial reality mirror onto the wall of the private room. The warning item OBJ is indicated in the displayed artificial reality mirror PRO, as depicted in Figures 5A and 5B. Once the warning item or shoes are placed in the possessions sorting machine, other scans are initiated for both the person and the items. Once the scans are complete, the sorting of the person is finished. The video system monitors the passenger's behavior to ensure compliance with abandonment requirements and to detect any unusual behavior.

[0087] 5. Selection and review of possessions The belongings screening procedure is guided by the passenger self-screening device interface. Passengers are instructed to place all accessible belongings, along with other items to be abandoned, into the belongings screening machine. The passenger self-screening device's belongings screening machine consists of a primary screening system sensor and an automatic warning deactivation capability. Both are initiated when the doors of the belongings screening machine are closed and locked during the screening process. A video system monitors that all items have been placed in the belongings screening system. The passenger interface guides the passenger through the progress and status of the belongings scanning. If the accessible belongings system and automated threat recognition (ATR) do not detect any threats, prohibited items, or explosives, the passenger may retrieve their belongings. The passenger self-screening device interface instructs the passenger to proceed to the gate as they are permitted, and the doors of the passenger self-screening device open automatically.

[0088] Fixed CT Primary Accessible Property Selection and Review System Figures 7A to 7C depict three possible configurations in which a compartment forms a passageway between an entrance side for passengers being screened and an exit side for screened passengers. The entrance side of the compartment can be closed by a sliding door SD1, and the exit side can be closed by a sliding door SD2. When a passenger identifies themselves and enters, sliding door SD1 closes. Sliding door SD2 remains closed until the screening process is complete and no further warnings are issued. In Figure 7A, a baggage drop-off station HLDS is located on the entrance side, and passengers can retrieve their baggage after being screened. After exiting the compartment through exit door SD2, passengers retrieve their baggage at a baggage retrieval station HLRS. A baggage scanner HLSA is located between the drop-off station and the retrieval station, for example, adjacent to the compartment, to scan baggage while passengers are being screened in the compartment.

[0089] Figure 7B depicts a similar configuration, where a passenger takes their luggage into a compartment to deposit it into a drawer DRW. A baggage sorting and inspection device (HLSA) is located adjacent to the compartment, and luggage is fed from the drawer by a conveyor. After sorting and inspection, the luggage is transported back to the drawer so that it can be retrieved by the passenger before it exits the compartment through the sliding door SD2. Figure 7C depicts a variation of the embodiment in Figure 7B, where a passenger takes their luggage into a compartment to deposit it into a drawer DRW. A baggage sorting and inspection device (HLSA) is located adjacent to the compartment, and luggage is fed from the drawer by a conveyor. After sorting and inspection, the luggage is transported to a retrieval station (e.g., a drawer) outside the compartment on the exit side so that it can be retrieved by the passenger after it exits the compartment through the sliding door SD2. Therefore, once the screening process is complete, the passenger is asked to leave the compartment, thus allowing the next person to enter through the entrance in SD1 in order to begin scanning subsequent passengers, while the passenger who has left the compartment can easily retrieve their luggage.

[0090] 6. Remove the property warning. To clear a warning regarding a passenger's belongings, the passenger self-sorting and screening device interface allows the passenger to identify the item and instructs the passenger to remove it. The item is placed next to the bag on the scanner, and the scanning is repeated. Once the bag and item are cleared, the passenger is instructed to retrieve all items from the belongings sorting and screening and proceed to the gate.

[0091] If the bag and / or items are deemed unacceptable, the system automatically alerts an operator who is immediately dispatched to a passenger self-screening device to carry out further warning removal procedures.

[0092] The sorting and inspection device is - A baggage sorting and inspection device configured to scan baggage checked in by a person, which may further include a primary scanner and an X-ray diffraction scanner. The control device is - The baggage is scanned by a primary scanner to generate primary scanner output data associated with the baggage scan. - Determine areas of interest in the baggage from the primary scanner output data. - The X-ray diffraction scanner is operated to scan areas of interest on the baggage and generate X-ray diffraction output data associated with the scanning of the baggage by the X-ray diffraction scanner. - Process primary scanner output data and X-ray diffraction output data to determine whether a warning signal is generated, and, - If generated, output a warning signal. The baggage sorting and inspection device is configured to operate in this manner.

[0093] 7. Passenger Departure Passengers depart on their journeys, and the passenger self-selection and screening device can then screen the next passenger.

[0094] The arrangement of multiple sorting and inspection devices, as depicted and described with reference to Figures 7A to 7C, is shown in the front view of Figure 8A and the rear view of Figure 8B. The sorting and inspection devices are connected to each other to form a row, thereby allowing the exit doors of the individual rooms to open to the exit side (EXT), while all the entrance doors of the individual rooms connect to the entrance side (ENT). As depicted in Figures 8A and 8B, the row of sorting and inspection devices is meandering to minimize the overall required floor space.

[0095] Figure 6A depicts the compartments of the sorting and inspection device SD and the baggage sorting and inspection device HLSA. The compartments and baggage sorting and inspection device are equipped with multiple baggage unloading stations HLDS on the entrance side of the compartments and multiple baggage retrieval stations HLRS on the exit side of the compartments. A conveyor transports baggage from the deposit station to the retrieval station. The baggage sorting and inspection device can be bidirectional, meaning that baggage can be fed from left to right or right to left (when viewed in the plane of the drawing). To increase transport capacity, the conveyor connects both the inlet / outlet of the baggage sorting and inspection device to the deposit station and the retrieval station. Due to its bidirectional nature, if the sorting and inspection of trays is repeated (for example, at the command of an operator), the bidirectional conveyor can transport the trays back to the baggage sorting and inspection device. Since baggage check-in and baggage retrieval can take up more time in each person's screening process than baggage screening alone, the capabilities of the baggage screening device and the ability of the screening device SD to screen individual cabin cabins can be used more efficiently, while still allowing people to check in their baggage and easily retrieve it. Instead of a single screening device, i.e., individual cabin cabins, a row of screening devices may be used, as depicted and described with reference to Figures 8A and 8B. Thereafter, passengers can proceed from a baggage unloading station to the entrance side of a row of screening devices, and after being screened by one of the screening devices, passengers can proceed from the exit side of the row of screening devices to a baggage retrieval station to retrieve their baggage.

[0096] Figure 6B depicts a multi-baggage sorting and screening system (HLSA) comprising multiple baggage unloading stations (HLDS) and multiple baggage retrieval stations (HLRS). Similar to Figure 6A, conveyors connect the inlets / outlets of each baggage sorting and screening system to the deposit and retrieval stations. As conveyors extend along each of the baggage unloading stations and each of the baggage retrieval stations, baggage unloaded at a baggage unloading station can be transported by the conveyors to any of the baggage sorting and screening systems, such as the nearest one, if that system has sufficient sorting capacity available. Thus, surplus baggage unloaded near one of the baggage sorting and screening systems can be transported to other systems, allowing the baggage to be scanned by any one of the multiple baggage sorting and screening systems, thereby increasing the overall effective capacity. Similarly, baggage may be scanned by one of the baggage sorting and inspection devices and then transported to one of the baggage collection stations.

[0097] Figure 9 depicts two baggage sorting and inspection devices, HLSA1 and HLSA2, with a conveyor CON between them, on which a shielding body SHD is provided to shield against X-ray radiation. Conventional lead flaps that may interfere with baggage transport may be omitted. Loading ports LP and DP, having a transport direction LPCON perpendicular to the direction between the baggage sorting and inspection devices, are connected to the deposit station HLDS and the retrieval station, and lead curtains and loading port screens may be provided.

[0098] A sorting and inspection system may be provided, further comprising a sorting and inspection device configured to operate at at least two different detection rates. A detection rate for the sorting and screening system may be defined to determine the required detection rate for the sorting and screening system. One of the detection rates of the sorting and inspection devices may be selected to match the detection rate of the sorting and inspection system. The command may be sent to the control device of the sorting and inspection device so that it operates at a detection rate selected to match the detection rate of the sorting and inspection system.

[0099] The detection rate of the sorting and inspection device may determine the detection rate of safety hazards detected in people, luggage, and / or people's footwear. [Explanation of Symbols]
