Intelligent locker

Abstract

An intelligent locker includes a locker body, a door, a lock, a biometric scanning device, and a controller. The biometric scanning device captures user biometric information to determine identity. Upon authentication, the controller unlocks the door and performs at least one identity-based operation, such as adjusting a motorized shelf to provide personalized storage access. The motorized shelf can be repositioned horizontally, vertically, or at an incline to optimize item retrieval. The locker can also include multiple compartments, each with dedicated access. The controller can limit access based on user attributes, such as age, and can be integrated with a temperature or humidity control system for secure storage.

Description

Technical Field

[0001] This invention relates to lockers with controlled access, and more specifically, to a smart locker equipped with a biometric authentication system and personalized access and internal adjustments based on user identity. Background Technology

[0002] Safes, refrigerated lockers, and secure lockers are commonly used to store valuable or restricted items. Traditional storage solutions rely on mechanical or electronic locks that require a physical key, password, or PIN code for access. While these methods effectively prevent unauthorized entry, they often lack user-specific adaptability and may not be convenient for frequent use.

[0003] Recent advancements in biometric authentication, such as facial recognition, palm scanning, fingerprint recognition, and iris recognition, have enhanced security by enabling more personalized and tamper-proof access control. However, traditional biometric storage solutions primarily focus on access authorization, offering no further customization in terms of storage organization or retrieval assistance. For example, existing solutions do not tailor their internal configurations to different users, nor do they facilitate bootstrapping of storage items.

[0004] Furthermore, many storage systems are designed with a static interior, requiring users to manually locate and retrieve items. This can be inefficient, especially in lockers with multiple compartments or high-security enclosures. A system that intelligently adjusts storage configuration based on user identity—for example, by adjusting shelf positioning, illuminating specific compartments, or guiding the retrieval process—will significantly improve convenience, security, and user experience.

[0005] Therefore, there is a need for a smart locker that combines biometric authentication with adaptive internal mechanisms to allow secure, user-specific access while optimizing storage organization and retrieval efficiency.

[0006] The above background information is provided only to aid in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0007] A system comprising one or more computers can be configured to perform specific operations through software, firmware, hardware, or a combination thereof. These components are executed during system runtime to perform the specified operations. Similarly, one or more computer programs can be designed to perform specific operations by including instructions that, when processed by a data processing device, cause the device to perform those operations.

[0008] In one aspect, a smart locker may include a locker body operably connected to a door. The door is secured in a closed position by a lock. Inside the locker body, a shelf is placed for storing items. The locker also includes a lighting system for improving visibility and a biometric scanning device connected to the locker body. A controller operably connected to the biometric scanning device and the lock is configured to determine the user's identity based on biometric information captured by the scanning device. After verifying the user's identity, the controller unlocks the door and performs at least one identity-based action tailored to the user. These actions may include adjusting the shelf position in a manner customized for a specific user or controlling the lighting system. Other embodiments of this aspect may include corresponding computer systems, devices, and computer programs stored on one or more computer storage devices, each computer storage device being configured to perform the described methods.

[0009] Smart lockers may include motorized shelves, and controllers may be configured to automatically adjust their position based on the identity of an authenticated user. This adjustment facilitates the retrieval or placement of items. The controller can reposition the shelves by extending them outwards or adjusting them vertically to create additional storage space. In some embodiments, the motorized shelves may tilt to further optimize item retrieval. The motorized shelves may be mounted on a slide rail system for horizontal movement via at least two horizontally arranged slide rails, or vertical movement via at least two vertically arranged slide rails, both driven by motors.

[0010] The lighting system within the locker can include multiple indicator lights. To improve usability, the controller can selectively activate portions of these lights based on the identity of an authenticated user, directing them to specific items or compartments. If the locker includes multiple compartments, the controller can identify the compartment associated with an authenticated user and activate the corresponding indicator light, guiding them to the correct storage area. The controller can also adjust the brightness or direction of the lighting system, settings that can be customized to user preferences.

[0011] The biometric scanning device may include at least one indicator light that provides a visual cue corresponding to the unlocked cubicle. Once the system verifies the user's identity, the indicator light may display a specific lighting pattern to indicate which cubicle has been unlocked. This pattern may include changes in shape, position, color, brightness, or flashing behavior. Furthermore, the controller may estimate the user's age based on biometric data and restrict access to certain cubicles if the user does not meet a predefined age threshold.

[0012] In some embodiments, the smart locker may include multiple individual compartments, each with its own dedicated door and lock. The controller unlocks only the compartment corresponding to an authenticated user, while keeping the other compartments secure. At least one compartment may be designed as a controlled environment, incorporating a temperature control device. The controller can adjust the compartment's temperature according to predefined settings suitable for storing items.

[0013] Smart lockers may also include internal storage compartments within the main locker. These internal compartments have their own doors and locks, requiring additional authentication in addition to unlocking the external locker. Biometric scanning devices can be shared between the external and internal locks; in some implementations, unlocking the internal compartment requires at least two different users to perform biometric scans simultaneously or consecutively. The controller ensures that the internal lock can only be unlocked after the external lock has been released.

[0014] Biometric scanning devices may include facial scanning devices, fingerprint scanning devices, iris recognition modules, or palm scanning devices. They can be placed on locker doors, locker bodies, or other suitable locations. The described technology can be implemented through hardware, software, methods, or combinations thereof, and can be stored on a computer-readable medium.

[0015] In another aspect, a method may include capturing a user's biometric information via a biometric scanning device. The method also includes identifying the user based on the captured biometric information. If the user is authenticated, the method proceeds to unlock the locker door. Once unlocked, the system performs at least one identity-based operation, such as vertically or horizontally adjusting the position of the motorized shelf to facilitate item retrieval or placement, and controlling a lighting system to provide user-specific lighting conditions within the locker. Other embodiments may include corresponding computer systems, apparatus, and computer programs stored on one or more computer storage devices, each computer storage device configured to perform the described method.

[0028] The present invention provides an intelligent locker, which aims to solve the problems existing in the prior art.

[0029] The technical solutions of the present invention and how they solve the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This invention relates to a smart locker with biometric authentication, automated shelving, or adaptive lighting systems for secure and user-specific storage. It enhances security and accessibility, allowing only authorized users to access stored items while dynamically adjusting the internal configuration. This system is ideal for high-security storage such as safes for valuables, medicine cabinets, and filing cabinets, ensuring restricted access in government, legal, financial, and healthcare settings. In the retail and hospitality industries, it can control access to age-restricted products, hotel minibars, and luxury goods, preventing unauthorized use.

[0031] Beyond indoor applications, smart lockers are also valuable in industrial and outdoor storage, including secure delivery lockers, warehouse inventory management, and construction tool storage. They support contactless package retrieval for e-commerce and last-mile delivery, ensuring safe and efficient storage in residential, commercial, and unattended locations.

[0032] Figure 1A and 1B An example exterior of a smart locker according to an example embodiment is shown.

[0033] Figure 1AA single-layer smart locker is depicted, comprising a locker body 1 forming an enclosed storage space, a door 2 operably connected to the locker body to allow entry, and a lock 3 securing the door in a closed position. A biometric scanning device 5 is connected to the locker body and configured to capture biometric information from a user. A controller within the locker is operably connected to the biometric scanning device 5 and the lock 3, thereby enabling identity-based authentication and access control. Upon successful biometric authentication, the controller unlocks the lock 3, allowing access to the storage space.

[0034] Figure 1B This demonstrates a two-tiered smart locker configuration that expands by incorporating additional storage compartments with corresponding second doors and locks. Figure 1A This is a single-layer embodiment. This multi-compartment design allows for segmented access control, ensuring that different users can be granted access to specific compartments based on their biometric credentials. In some embodiments, a single biometric scanning device 5 is used to authenticate users and control doors and locks individually, thereby reducing hardware costs while maintaining security. The controller determines which compartment should be unlocked based on the verified user's identity and can perform identity-based operations, such as adjusting the position of internal shelves or controlling the lighting system to guide the user to the appropriate storage area.

[0035] In some embodiments, the smart locker also includes a lighting system disposed within the main body of the locker. Figure 1A and 1B (Not shown in the image). After successful authentication, the controller can selectively activate certain indicator lights or adjust the brightness and direction of the lighting to facilitate item retrieval. The lockers may also feature adjustable shelves (…). Figure 1A and 1B (Not shown in the image), this shelf can be repositioned or extended to provide enhanced accessibility based on user identity. These features enable efficient and personalized access to stored items while maintaining a high level of security and availability.

[0036] The biometric scanning device 5 used for authentication can use at least one of the following devices: a face scanning device, a fingerprint scanning device, an iris recognition module, or a palm scanning device, thereby allowing for flexibility in security implementation based on user preferences and operational requirements. Although Figure 1A and 1B The illustration shows a biometric scanning device 5 mounted on the locker body 1, but in some embodiments, it can be mounted on the door 2 or other suitable locations to optimize usability and accessibility. Depending on security needs, aesthetic preferences, or environmental conditions, the door 2 and locker body 1 of the smart locker can be constructed from various materials, including metal, wood, or glass. Similarly, the lock 3 can be implemented using different locking mechanisms, such as mechanical locks, electronic locks, or combination locks, providing adaptable security configurations for different applications.

[0037] In some embodiments, the smart locker also includes a controller, which may be a computing device equipped with a processor and memory, responsible for managing the various components of the locker. The controller is operatively coupled to the biometric scanning device 5 and configured to control one or more smart functions of the locker, including the lock 3, movable shelves, lighting systems, and other controllable devices such as humidifiers or temperature control systems. The controller may be located inside the locker. Upon successful user authentication, the controller not only unlocks the door 2 but also performs identity-based operations, dynamically adjusting the internal environment and storage configuration to optimize accessibility and security based on the user's identity.

[0038] In some embodiments, the controller can be configured via an external application, such as a web-based platform or mobile application, enabling users to manage their access credentials, adjust operating settings, and remotely monitor locker activity. Alternatively, a user interface, such as a touchscreen, keyboard, or voice-activated assistant, can be provided on the locker to allow direct interaction with it. Through these interfaces, users can register their biometric information, set custom operating preferences, and configure locker functionality after unlocking. For example, after authentication, users can predefine actions such as moving shelves horizontally or vertically to create additional space, adjusting the direction or brightness of the lighting system to focus on specific items or areas, or setting environmental conditions such as humidity or temperature to preserve sensitive materials.

[0039] In some embodiments, the biometric scanning device 5, the controller, or both work in concert to estimate user attributes beyond identity, such as age or gender, based on biometric data. These additional attributes allow for more granular control over access permissions and operational settings. For example, lockers can be configured to restrict access to certain compartments or specific items for users who meet age requirements, such as preventing users below a legal age threshold from accessing alcohol, firearms, or controlled substances.

[0040] In some embodiments, the biometric scanning device 5 of the smart locker is implemented as a palm scanning device, providing a highly secure and reliable method for user authentication. A palm scanning device is an advanced biometric tool that can identify an individual based on at least one unique feature of the palm, including palm surface patterns, palm prints, and palm vein structures.

[0041] For example, a palm scanning device can operate using three main identification technologies. The system performs palm recognition, ensuring the scanned object is indeed a palm and using computer vision technology to filter out non-palm objects. This step enhances security by preventing spoofing attempts using human or non-human objects. Once a valid palm is detected, the system performs palmprint recognition by capturing infrared images of the palm surface and analyzing unique features such as lines, creases, and texture patterns. These patterns are then compared to stored templates for authentication. For palm vein recognition, infrared imaging is used to detect unique vein patterns under the skin. Because hemoglobin in veins absorbs infrared light, the captured vein patterns provide additional internal biometric markers, making them virtually impossible to copy or forge. Two or more of palm recognition, palmprint recognition, and palm vein recognition can be implemented as a biometric scanning device in a smart locker.

[0042] In certain use cases, palm scanning is preferable to fingerprint scanning for several reasons. Unlike fingerprints, which can be extracted from surfaces and potentially copied, palm vein patterns are located inside the body and are not easily stolen or copied. This makes palm scanning a highly secure anti-spoofing technology. Furthermore, palm vein patterns remain consistent over time, unaffected by aging, environmental conditions, or physical wear, while fingerprints can degrade due to skin damage, moisture, or dirt. Palm scanning can be implemented contactlessly, eliminating the need for physical touch and reducing the risk of cross-contamination, which is particularly beneficial in high-traffic or hygiene-sensitive environments.

[0043] In some use cases, palm scanning offers greater privacy and security compared to facial recognition. Because palm vein patterns are internal and invisible to others, they cannot be captured or copied without the user's knowledge, unlike facial images which can be captured or reconstructed from digital sources. Facial recognition systems also face accuracy challenges due to lighting conditions, aging, and changes in facial expressions, while palm vein patterns remain highly stable and consistent over time.

[0044] Figure 2A and 2B An example interior of a smart locker according to an example embodiment is shown. Figure 2A The diagram illustrates a two-compartment configuration, where the main locker 1 includes shelving that divides the interior into upper and lower compartments. This design allows for the separation of stored items into individual sections while maintaining a secure and structured storage layout. The shelving provides separation between the compartments, ensuring that different categories of items remain isolated.

[0045] Figure 2BAn embodiment of an electrically powered and movable shelving unit, allowing for dynamic storage configuration based on user identity, is illustrated. A controller is operatively coupled to the electrically powered shelving unit and configured to automatically adjust its position as part of identity-based operations. Depending on the authenticated user and their predefined settings, the electrically powered shelving unit can extend outwards using rails to facilitate item retrieval (e.g., ...). Figure 2B (as shown), or adjust its height vertically ( Figure 2B (Not shown in the image) to create additional space.

[0046] In some embodiments, the controller can adjust the position of the motorized shelving in various ways. The shelving can be configured to move horizontally outward from the main body of the locker to display items for easy access. Alternatively, it can be driven by a motor through at least two vertically arranged slide rails (such as…). Figure 4 (As shown) to vertically reposition the shelves, enabling them to move up or down to accommodate different storage needs.

[0047] In another variation, the electric shelving can be tilted ( Figure 2B or Figure 4 (Not shown in the image) to increase available space for retrieval or placement, providing additional flexibility for organizing and accessing items. These moving mechanisms can be implemented using an electric slide system with at least two tracks arranged horizontally or vertically, allowing the shelves to be dynamically positioned based on stored items and user preferences.

[0048] In some embodiments, the smart locker is also configured to detect whether an item has been placed on or removed from the motorized shelf, and automatically restore the shelf's position based on this detection. This feature ensures that the shelf returns to its original position after the item is retrieved. Similarly, when an item is placed on the shelf, the system confirms the placement and then restores the shelf to its default position, ensuring secure storage.

[0049] To achieve this functionality, smart lockers can be equipped with at least one detection mechanism, such as a weight sensor, light sensor, camera, motion sensor, or any combination thereof. The weight sensor can be positioned below the motorized shelf to detect weight changes when items are added or removed. When the system detects a weight reduction indicating the item should be retrieved, the controller signals the motorized shelf to return to its default position. Similarly, when the sensor detects an increase in weight, confirming a new item has been placed, the controller ensures the storage process is completed before returning the shelf to its original position.

[0050] Alternatively, smart lockers can use optical detection systems, such as light sensors or cameras (like depth cameras), to monitor the placement of items. Light sensors located above or beside the shelves can detect changes in light intensity or shadows to confirm whether items have been removed or added. In more advanced implementations, an integrated camera system can analyze real-time visual data to determine the presence of objects on the shelves. The controller processes this visual information and determines whether to restore the shelf's position based on detected changes.

[0051] In some implementations, the locker may include motion sensors to detect physical actions of placing or retrieving items. These sensors can recognize user hand movements or object displacement, sending signals to a controller to restore the shelf's position accordingly. Furthermore, the system can combine multiple detection methods, such as weight sensors and cameras, to improve the accuracy and reliability of determining whether items have been successfully placed or removed.

[0052] Figure 3A and 3B Another example interior of a smart locker according to one example embodiment is shown. Figure 3A A three-compartment configuration is shown, where the locker body 1 includes two fixed shelves that divide the interior into three vertically stacked compartments. Depending on usage, the smart locker may include more compartments. In some embodiments, the compartments may be arranged horizontally to allow side-by-side storage, or in a combination of vertical and horizontal configurations to optimize space utilization and accessibility according to specific user needs.

[0053] Figure 3B Another embodiment is shown, in which at least one shelf is movable, providing a more adaptable storage system. Similar to... Figure 2B In the embodiments described, the movable shelving can be connected to a motor and slide rails, allowing it to extend outwards, adjust its height, or tilt for easy retrieval of items. If multiple shelving units are configured to be movable, they can be set to have the same or different movement capabilities. For example, two shelving units can be configured to move horizontally, allowing different compartments to extend outwards independently. Alternatively, one shelving unit can be designed to move horizontally while another can move vertically, dynamically expanding or compressing compartment space to meet various storage requirements.

[0054] Figure 5 An example lighting system in a smart locker according to an example embodiment is shown. Figure 5 The specific embodiment shown depicts a three-compartment configuration, where each compartment is equipped with dedicated lighting, such as indicator lights. This configuration is for illustrative purposes only; depending on usage, smart lockers may include fewer or more compartments arranged in various ways, and some compartments may share lighting.

[0055] In some embodiments, the lighting system of the smart locker includes multiple indicator lights that a controller selectively activates based on the user's identity. When a user accesses the smart locker, the controller identifies a specific compartment or item associated with that user and activates a portion of the indicator lights accordingly. This personalized lighting system helps guide users directly to their authorized compartment or stored item, improving efficiency and user experience. For example, if only the middle compartment is allowed access, the corresponding indicator light for that compartment will illuminate, while other compartments remain off, reinforcing restricted access.

[0056] In some embodiments, the controller also customizes the lighting system by adjusting the brightness or direction of the light based on user preferences. Users can pre-configure lighting settings so that when they enter a locker, the brightness increases for better visibility, or the light direction shifts to a specific area or item within the compartment. This identity-driven lighting adjustment improves usability, especially in low-light environments or high-security storage applications where users require precise guidance to quickly retrieve items.

[0057] In some embodiments, the lighting system can also be used as a compartment identification mechanism. In some embodiments, the biometric scanning device 5 includes at least one indicator light as part of the lighting system, which can be configured to provide a visual cue corresponding to an unlocked compartment. Once the biometric scanning device verifies the user's identity, the locker unlocks the designated compartment, and the indicator light is configured to display a specific lighting pattern to signal the unlocked compartment.

[0058] Lighting patterns can vary depending on different attributes and user-defined settings. For example, a lighting system can adjust its shape, position, color, brightness, or flashing pattern to indicate a specific compartment that has been accessed. In some cases, flashing indicator lights can be used to improve visibility, while in others, a specific color coding system can be used to distinguish different types of compartments (e.g., red for restricted compartments, green for general access, and blue for temperature-controlled storage).

[0059] As another example, indicator lights can dynamically change color based on whether a user has full administrative access, limited access, or age-restricted access to a particular compartment. A steady white light might indicate general entry, while a pulsed yellow light could serve as a warning indicator for compartments containing sensitive or hazardous materials. In advanced implementations, the lighting system can project patterns or symbols onto the compartment door or locker body to visually guide the user, such as a flashing arrow pointing to unlock the compartment.

[0060] As another example, in lockers designed for temperature-sensitive items, the system might include heat-responsive indicator lights, with blue lighting indicating cooled storage compartments and orange or red lighting indicating heated compartments. In some cases, the lighting system may also integrate sound or haptic feedback, providing a buzzing sound or slight vibration when an access event is triggered, further enhancing user awareness and interaction.

[0061] Figure 6A An example cascading configuration of a smart locker according to an example embodiment is shown. Figure 6A The configuration features a two-layer security system, with the main (outer) locker surrounding the inner locker, providing an additional layer of security for high-value or restricted items. The outer locker includes an outer door secured by an outer lock, while the inner smart locker has an inner door secured by an inner lock.

[0062] In this cascaded configuration, the smart locker's controller can be operatively coupled to both the outer and inner locks, allowing for tiered access control. In some embodiments, the controller applies different access permissions to each lock, requiring additional authentication steps to unlock the inner locker, rather than the steps required to unlock the outer locker. For example, users might need to provide a secondary biometric scan, enter a password, or use multi-factor authentication to access the inner compartment, ensuring that only authorized personnel with appropriate credentials can retrieve the most sensitive items.

[0063] In some embodiments, the biometric scanning device can be shared between the outer and inner lockers, meaning a single authentication device can be used to control access to both storage tiers. However, to unlock the inner locker, the system may require simultaneous or consecutive biometric scans from at least two different users to ensure compliance with a dual-authorization protocol.

[0064] Furthermore, in some embodiments, the controller enforces a sequential unlocking mechanism, requiring the outer lock to be unlocked before the inner lock can be accessed. This prevents direct access to the inner locker without first opening the outer storage compartment, adding an extra layer of security and access control.

[0065] In some implementations, a lighting system can be integrated with this cascaded storage design. Once the external locker is unlocked, the lighting system can highlight the internal locker, guiding the user through the next required authentication step. If two-factor authentication is required, the system can provide visual or audio prompts instructing the user to proceed to the second step of authentication before entering the internal compartment. This cascaded security model ensures a highly controlled access structure, making smart lockers ideal for multi-level security applications.

[0066] Figure 6B An example embodiment of a biometric scanning device for a smart locker is shown, according to an example embodiment.

[0067] exist Figure 6B In the first embodiment shown, the biometric scanning device includes a 3D facial recognition module. The 3D facial recognition module includes a first computing unit, a laser speckle projector, and an infrared detector, all of which are electrically connected. The laser speckle projector emits a structured infrared light pattern onto the face of a target user, thereby generating a speckle infrared projection. The infrared detector captures the reflection of this infrared speckle pattern and records the optical distortion caused by the three-dimensional contours of the user's face. The first computing unit then processes (e.g., using a 3D reconstruction unit) the detected distortion or displacement of the infrared speckle pattern and generates a corresponding depth facial image, which is used as a 3D representation of the user's face for authentication.

[0068] To enhance safety and prevent accidental overexposure to infrared radiation, the 3D facial recognition module may include a second proximity sensor. When the sensor detects that the user's face is too close to the module, such as within 15 centimeters of the device, the laser speckle projector automatically shuts off to avoid potential discomfort or interference.

[0069] In some embodiments, the 3D facial recognition module also incorporates an RGB camera module and an LED floodlight. The RGB camera captures a color image of the user's face, while the LED floodlight projects visible light onto the user's face to improve image clarity. An infrared detector simultaneously captures an infrared facial image based on the reflection from the LED floodlight illumination. A first computing unit processes the infrared and RGB images to determine whether the detected face belongs to a pre-authorized user stored in a whitelist database. This whitelist authentication can be performed using a pre-trained facial recognition model (e.g., via an app unit), allowing only pre-registered users to access the smart locker.

[0070] In the second embodiment shown in Figure 6, another 3D face recognition module may include a second computing unit, a light projector, and a time-of-flight (TOF) sensor. The light projector emits an infrared floodlight onto the face of the target user, while the TOF sensor receives the reflected infrared light and generates multiple infrared facial images within a predefined collection period. The second computing unit then processes the phase differences on these multiple images to calculate a highly detailed depth map of the user's facial surface.

[0071] In the third embodiment shown in Figure 6, the biometric scanning device uses a palm scanning device for user authentication. The palm scanning device provides highly secure biometric verification by analyzing unique palm features, including palm surface patterns, palm prints, and palm vein structures.

[0072] In one embodiment, the palm scanning device includes a computing unit, an infrared light source, and a near-infrared (NIR) camera, all operatively connected to process and verify a user's palm data. During operation, the infrared light source emits near-infrared illumination onto the user's palm, located above the scanning module. The NIR camera captures vein patterns beneath the skin, as hemoglobin in the veins absorbs infrared light, forming a unique vascular pattern unique to each individual. The computing unit processes the vein pattern, comparing it to pre-stored biometric data to verify the user's identity.

[0073] Palm scanning devices are highly secure because vein patterns are located inside the body, making them difficult to forge or copy. Unlike fingerprints, which can deteriorate over time due to wear and tear, palm vein patterns remain stable, ensuring consistent long-term authentication performance. Furthermore, because this technology is contactless, it eliminates concerns about hygiene and cross-contamination, making it ideal for shared storage applications where multiple users access the same locker.

[0074] In some implementations, palm scanning devices include anti-spoofing mechanisms to prevent unauthorized access attempts using fake palm images or artificial models. The system may include a second proximity sensor that detects whether the user's palm is too close to the scanning device and adjusts the illumination intensity accordingly. If the sensor detects an object closer than a predefined threshold (e.g., 5 cm), the system may temporarily disable the scanner to prevent accidental misreading or spoofing attempts.

[0075] In another embodiment, the palm scanning device also integrates an RGB camera and an LED floodlight to improve authentication accuracy. The RGB camera captures a full-color image of the user's palm, which can be used for surface palmprint recognition by analyzing the lines, creases, and ridges on the palm's exterior. The LED floodlight ensures consistent lighting conditions, enabling high-quality image capture in diverse environments. The computing unit processes the RGB palm image along with vein patterns, ensuring the analysis of multiple biometrics for authentication.

[0076] The following description illustrates several real-world embodiments of the above-described smart locker. Example

[0077] In some embodiments, smart lockers are designed for single-purpose storage applications, such as safes, alcohol coolers, humidity-controlled storage units, or other dedicated lockers. Figure 1A and 1BThe digital tag system in the locker includes a locker body 1, a door 2, a lock 3, and a biometric scanning device 5, which can be configured as a palm recognition module or a facial recognition module. The locker body 1 can be configured as a single-layer or multi-layer structure to accommodate different storage needs based on the size and quantity of items. Furthermore, depending on specific application requirements, the interior of the locker can be equipped with various organizational features, such as storage compartments, drawers, or slides.

[0078] Door 2 is operably connected to the locker body 1 and serves to enclose the storage space, ensuring the protection of stored items. The door can be made of metal, wood, or glass, allowing for customization based on security needs and aesthetic preferences. In some embodiments, the door includes a handle or other opening mechanism to facilitate user entry after successful authentication. Lock 3 provides a security mechanism to prevent unauthorized access and can be implemented as a mechanical lock, electronic lock, or combination lock according to user preferences and security requirements.

[0079] A biometric scanning device 5 is located on the door 2 or the main body of the locker 1 and serves as an authentication authority. This device may support palm recognition, facial recognition, or other biometric authentication methods. When a user scans their biometric information, the controller determines their identity and unlocks the lock 3 upon successful authentication, allowing access to the storage space. Furthermore, the controller is configured to perform identity-based operations, such as adjusting internal shelves, activating indicator lights, or modifying lighting settings based on the preferences of the authenticated user.

[0080] In some embodiments, the locker body 1 includes at least two independently activatable lighting elements. The lighting system is configured to selectively illuminate specific areas based on the user's identity determined by the biometric scanning device 5. The lighting system improves visibility within the locker, helping users quickly locate and retrieve items. For example, if a specific item is stored in a designated area, the corresponding lighting element will automatically turn on, providing clear visual guidance to the user. Brightness and lighting direction can also be dynamically adjusted based on predefined user settings.

[0081] In some embodiments, the locker body 1 also includes at least two indicator lights, which serve as visual guides to indicate the location or status of items. Similar to the lighting system, the indicator lights can be dynamically adjusted based on user authentication data. For example, when a user needs to retrieve a specific item, the corresponding indicator light will be activated, guiding the user to the precise storage location.

[0082] In another embodiment, the locker body 1 includes at least one electrically operated shelf configured to dynamically adjust its position based on biometric authentication data. A controller manages the movement of the electrically operated shelf, enabling it to expand storage space, reposition items, or push items outwards for easy access. The electrically operated shelf can adjust horizontally, vertically, or tilted according to user-defined preferences. For example, if a user frequently accesses a particular item, the shelf can be programmed to automatically extend outwards after authentication, allowing for quick and convenient retrieval. The controller can also customize the movement of the shelf based on individual user profiles, ensuring a personalized and intelligent storage experience. Example

[0083] In another embodiment, the smart locker can be designed as a multi-purpose storage unit with at least two independent compartments, each of which can be accessed and controlled individually. The locker body 1 includes at least two doors 2, at least two locks 3, and a biometric scanning device 5, which can be a palm recognition module or a facial recognition module. The biometric scanning device 5 can be located on the doors 2 or the locker body 1 and is used to authenticate the user before unlocking one or more compartments. A controller is operatively coupled to the biometric scanning device 5 and controls the selective unlocking of compartments based on user authentication data.

[0084] In some embodiments, two or more independent compartments can be arranged in various configurations, such as side-by-side (horizontally aligned), stacked (vertically aligned), or distributed at different heights and locations. This flexible compartment arrangement allows smart lockers to be customized to different storage needs, such as a refrigerated section for perishable foods and a drying compartment for documents, jewelry, or other valuables. Each compartment may have different environmental settings, allowing for precise control of temperature, humidity, or security levels.

[0085] In some embodiments, the lighting system includes multiple indicator lights that can be used to identify which compartment has been unlocked. The controller can adjust the shape, position, color, brightness, or flashing pattern of the indicator lights to visually indicate the currently accessible compartment. For example, when a user successfully authenticates, the indicator light associated with the authorized compartment may illuminate in a different color to guide the user to the correct area. Different colors can be used to indicate storage conditions, such as blue for a cold storage compartment, yellow for a humidity-controlled compartment, and green for general storage.

[0086] Furthermore, in some embodiments, the smart locker may include a physical interface, such as a button or touchscreen, allowing the user to pre-select a specific compartment before authentication. After selecting the desired compartment, a biometric scanning device 5 verifies the user's identity, and the controller unlocks only the corresponding door. Each compartment is independently controlled, with its own electronic or mechanical lock, ensuring secure and partitioned access management.

[0087] In some embodiments, at least one compartment includes an electrically operated shelf configured to adjust its position according to the preferences of an authenticated user. The electrically operated shelf may expand storage space, tilt for easier access, or automatically push stored items outward when the compartment is unlocked. A controller manages the movement of the shelf in response to specific user preferences, thereby enabling a customized retrieval experience.

[0088] To enhance storage conditions, at least one compartment may be configured as a temperature-controlled environment, incorporating insulation, temperature sensors, cooling units, or heating elements to maintain a stable internal temperature. Similarly, in some embodiments, at least one compartment may be equipped with a humidity control system, including humidity sensors, controllers, and humidifiers, to ensure that stored items are kept under optimal environmental conditions.

[0089] In some embodiments, at least one compartment is equipped with ultraviolet (UV) disinfection technology, enabling the storage of items to be disinfected with ultraviolet light. This is particularly useful for medical storage, high-value electronics, or sensitive materials, as the UV lighting system can kill bacteria and prevent contamination, while protecting items from UV damage through controlled exposure. Example

[0090] In another embodiment, the smart locker is designed with a dual-layer security system, providing two levels of authentication and access control. This cascaded security design consists of an external locker and an internal storage compartment, each with its own independent locking and authentication mechanisms. The external locker serves as the main enclosure, while the internal storage compartment provides an additional layer of protection for high-value or restricted items. The system employs biometric scanning devices, such as facial recognition or palm scanning modules, to manage access.

[0091] The outer locker body 1 forms the main structure of the smart locker, housing the internal storage compartment. It is made of high-strength materials and features tamper-proof, pry-proof, and impact-resistant properties. The outer door 2 surrounds the storage space and is equipped with a lock 3 and a biometric scanning device 5 for access control. A controller is operatively coupled to the biometric scanning device, ensuring that only authorized users can unlock the outer compartment. The lock 3 can be implemented as an electronic lock, preventing unauthorized access unless biometric authentication is successfully completed.

[0092] Inside the outer lockers, an inner storage compartment provides an additional level of access restriction. The inner compartment has its own door (inner door) and lock (inner lock), ensuring that even if a user enters the outer locker, they must undergo additional authentication to open the inner storage space. A biometric scanning device 5 may be shared between the outer and inner locks, or a dedicated two-factor authentication step may be required to unlock the inner compartment. In some embodiments, the authentication requirements for the inner compartment differ from those for the outer compartment, ensuring that only users with the appropriate access level can retrieve specific stored items.

[0093] In some implementations, smart lockers require two-factor authentication to access the internal storage compartments. The biometric scanning device 5 can be configured to require simultaneous or sequential authentication from at least two different users to ensure that no single user can unlock the internal compartments alone. This feature is particularly useful in high-security environments such as government agencies, financial institutions, or pharmaceutical storage facilities, where access restrictions require dual approval.

[0094] The smart lockers are equipped with a sequential unlocking mechanism that ensures the outer door must be successfully unlocked before entering an inner compartment. The controller enforces this access sequence to prevent unauthorized users from attempting to bypass security protocols. This layered access structure adds an extra layer of control, particularly useful for storing confidential documents, controlled substances, or secure financial vaults.

[0095] In some embodiments, the smart locker includes an integrated alarm system. The controller triggers an alarm if an unauthorized access attempt is detected, or if biometric authentication fails multiple times. The alarm system can be configured to issue audible or visual alerts to notify nearby personnel of security vulnerabilities, send security alerts to a central monitoring system, provide real-time access logs and security event tracking, or temporarily disable authentication attempts after a set number of failed access attempts to prevent brute-force attacks. Example

[0096] In another embodiment, the smart locker includes an electrically operated shelving system capable of dynamically configuring storage based on user authentication and predefined preferences. Movable shelves are installed within the locker body 1 and configured to move horizontally or vertically, thereby optimizing storage space and making it easier to retrieve stored items. A controller operatively coupled to a biometric scanning device 5 identifies the user and adjusts the shelf position accordingly for easy access.

[0097] In some implementations, the motorized shelving is mounted on a pair of horizontally arranged rails within the main body of the locker. A motor is connected to the rail system, enabling the shelving to move synchronously. After user verification, the shelving can extend outwards to push items forward for retrieval, or retract inwards to securely store items inside the locker. Horizontal movement allows for seamless item retrieval without requiring the user to delve into the storage space.

[0098] In other embodiments, the motorized shelving is mounted on at least two vertically aligned rails, allowing it to move up or down within the locker. The vertical sliding system includes a motor that drives the synchronized movement of the rails, repositioning the shelving to create additional storage space or facilitate retrieval. This configuration is particularly useful for multi-level lockers where users may need access to different shelving locations based on their identity and storage permissions. Example

[0099] In another embodiment, the smart locker serves as a shared storage system, incorporating depth cameras, network communication modules, and intelligent monitoring capabilities to facilitate real-time tracking and management of stored items. This embodiment is particularly suitable for shared storage systems, such as rental lockers for musical instruments, gun storage with automated verification, or self-service rental stations that track item usage, condition, and pricing based on predefined metrics.

[0100] The locker body 1 includes at least one depth camera for monitoring the integrity, condition, and status of the stored items. In some embodiments, at least two depth cameras are mounted inside the locker at different angles, allowing for 3D reconstruction of the stored objects. The system stitches together point cloud data from multiple depth cameras to generate a comprehensive 3D representation of the stored items, which is then analyzed to determine whether the objects are intact, missing, or damaged. In specific applications, such as gun storage, the system can be configured to analyze specific object attributes, such as the location of safety switches, to ensure the safe storage of items.

[0101] The smart lockers also include a network transceiver, enabling them to communicate with external devices such as mobile phones or remote monitoring systems. This feature supports real-time status updates, allowing users or administrators to remotely check the status of items stored in the lockers. Remote access enhances security and operational efficiency, enabling storage facilities to be managed without the need for physical inspection.

[0102] In shared storage scenarios, such as rental locker systems, smart lockers can automatically calculate usage fees based on various parameters, including changes in weight, volume, or quantity. When using weight-based pricing, the locker is equipped with a scale that detects weight reduction when items are removed and calculates the corresponding fee. To ensure accurate monitoring, a camera module is also included to verify that removed items are identical to those originally stored and that no foreign objects have been added.

[0103] For volume-based pricing, depth cameras measure changes in the volume inside the locker and detect whether items have been replaced or altered. Similarly, for quantity-based pricing, the camera module detects the number of items removed and calculates the corresponding fee based on the detected number of items.

[0104] In addition, smart lockers may include a barcode recognition module for identifying barcode labels affixed to stored items. By utilizing barcode scanning technology, the system can automatically record the entry and exit of items, enabling seamless automated billing and inventory tracking. In some embodiments, a combination of weight measurement and depth cameras is used to verify whether the stored objects have been tampered with, replaced, or mixed with foreign objects, thereby ensuring higher accuracy in shared use applications. Example

[0105] In another embodiment, the smart locker includes a control screen that allows users to select specific storage items, improving convenience and accessibility, especially when multiple items are stored in the locker. The control screen supports intelligent item selection and retrieval assistance, reducing the need for users to manually search for items within the locker. After selection, the system can highlight the selected item using internal indicator lights or automatically adjust the storage configuration to push items forward for retrieval.

[0106] In one embodiment, the control screen is externally mounted on the main body 1 of the locker and utilizes touchscreen technology to provide an intuitive and interactive interface. The touchscreen supports multiple input methods, such as clicking, swiping, and scrolling, enabling users to efficiently browse stored items and select specific objects. Once an item is selected, the user performs biometric authentication via a biometric scanning device 5, such as palm or facial recognition. Upon successful authentication, a corresponding indicator light inside the locker illuminates, guiding the user to the correct item's location. Simultaneously, the locker door 2 unlocks and opens automatically, allowing the user to easily retrieve the item.

[0107] In some embodiments, the smart locker features a transparent door, allowing users to visually inspect the stored contents without opening the locker. This design improves efficiency and user experience, as users can identify the desired item before initiating the retrieval process. The transparent door can be made of durable materials, ensuring security while maintaining visibility.

[0108] In another embodiment, the smart locker uses user behavior data to personalize the retrieval process. After biometric authentication, the system automatically displays frequently accessed items on the control screen, allowing users to quickly select frequently used items. If the user confirms their selection, or if no interaction occurs within a predefined time, the system automatically proceeds with retrieval by unlocking the door and adjusting the internal storage configuration. This predictive retrieval feature simplifies access, reduces interaction time, and improves user efficiency.

[0109] In some embodiments, the controller integrates indicator lights and a motorized shelving system to ensure items are visually highlighted and physically repositioned for easy retrieval. When an item is selected, the corresponding indicator light illuminates, and the motorized shelving can extend outward or adjust its height for easier access.

[0110] Figure 7 An example method for controlling access to a smart locker is shown according to an example embodiment.

[0111] In some embodiments, one or more steps of process 700 may be performed by a computing device associated with the smart locker. The process begins by capturing the user's biometric information via a biometric scanning device (block 702). For example, the device may use a biometric scanning device as described above to capture biometric data, such as facial recognition, palm scanning, fingerprint scanning, or iris recognition.

[0112] Next, process 700 includes determining the user's identity based on the captured biometric information (block 704). The device processes the biometric data and matches it against stored credentials to verify the user's identity. If the user successfully authenticates, process 700 proceeds to unlock the locker door (block 706). In this step, the device releases the lock used to secure the door, allowing the authenticated user access.

[0113] Once access is granted, process 700 includes performing at least one identity-based operation (block 708) based on the verified user identity. The identity-based operation may include vertically or horizontally adjusting the position of at least one motorized shelf within the locker to facilitate the retrieval or placement of items. Furthermore, the system may control a lighting system to provide customized lighting conditions, such as adjusting brightness, color, or direction based on the user's identity to highlight specific compartments or items.

[0114] although Figure 7The specific steps of process 700 are shown, but the process may include additional steps, fewer steps, alternative steps, or steps arranged in a different order depending on the implementation. Furthermore, two or more steps in process 700 may be performed simultaneously rather than sequentially to optimize processing efficiency.
