Description:FIELD OF THE INVENTION

[0001] The present invention relates to peripheral devices and in particular to a personal item handling and management device that is capable of securely receiving and organizing student belongings. The device features automated content analysis, security monitoring against tampering and unauthorized access, environmental control for preserving items, and integrated fire suppression, all while streamlining academic material preparation.

BACKGROUND OF THE INVENTION

[0002] Efficient personal item handling and management are crucial in modern environments, especially for individuals like students who carry diverse belongings daily. Users frequently face challenges such as misplacing items, particularly small or critical ones, or struggling with the sheer volume and variety of objects they need to carry. Furthermore, ensuring the security of valuables against theft or tampering, dealing with perishable items like food, and maintaining proper organization within limited space are constant concerns. The absence of automated assistance often leads to time wasted searching, potential health issues from mishandled food, and the risk of losing important academic materials or personal effects.

[0003] Traditional personal item management solutions primarily include traditional lockers and more recent smart locker means. Traditional lockers, while simple and inexpensive, suffer from significant drawbacks like reliance on physical keys, limited security against tampering or forced entry, and a lack of real-time monitoring. They offer no intelligence regarding contents, temperature control, or automated retrieval. Smart locker means address some of these by incorporating digital locks, app-based access, and basic monitoring. However, most still lack improved capabilities such as robotic manipulation for internal organization, integrated food preservation, sophisticated contraband detection, or dynamic fire suppression. Their primary function remains secure storage, falling short of a comprehensive, automated item management solution that actively assist users with diverse daily needs.

[0004] US9460412B2 discloses about an airport baggage handling system bag information, flight information and airport topology information are provided to a central processor which determines a path for the bag through the handling system. The bag is scanned at various points along the path and the scan time is compared with a predetermined arrival time for the bag at the scan point. A bag is marked at risk if it arrives at a scan point after the predetermined time and the system may suggest an alternative handling path for the bag if it is determined that the risk of the bag not making an outbound flight is too high.

[0005] US20050033666A1 discloses about a management server for managing inventory of articles and a terminal device for inquiring the condition of inventory are provided. The management server is provided with an inventory database and a database control portion for controlling input and output of data to and from the inventory database. The inventory database stores, as management information, information identifying articles and salespersons responsible for the articles as well as, for articles specified to be included in open inventory, information indicating that persons other than the salespersons responsible for the articles are permitted to sell the particular article. Furthermore, the management server accepts access by particular users from the terminal device to the management information on the articles included in ordinary inventory and also accepts access by users other than the particular users from the terminal device to the management information on the articles included in open inventory.

[0006] Conventionally, many devices are available in market for personal item management often focus solely on storage or basic security, lacking integrated features such as automated item sorting, environmental control, and real-time monitoring. They typically do not support robotic manipulation, automated food handling, or autonomous threat detection.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to combine item handling, automated sorting, environmental control, and real-time security. The device should further manage food preservation, detect threats, organize materials by schedule, and offer user interaction through a digital interface for alerts, overrides, and customization—providing a complete, automated personal item management solution.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to a personal item handling and management device that is capable of securely storing and organizing belongings. The device autonomously inspects contents for security, manages consumables, and provides real-time alerts. The device also includes improved safety features for fire suppression and unauthorized access prevention, ensuring comprehensive item protection and user convenience.

[0023] Referring to Figure 1, an isometric view of a personal item handling and management device is illustrated, comprising a housing 101 configured to receive and hold students’ belongings, a L-shaped telescopic link 102 installed via a ball and socket joint 103 within the housing 101, having a three-finger gripper 104, a camera 105 provided inside the housing 101, a dedicated food chamber 106 provided within the housing 101, a movable slider 107 mounted above a base portion of the housing 101, having an inspection unit 108 installed on the slider 107, an imaging unit 109 provided with outer portion of the housing 101, a front-facing louver arrangement 110 installed over an opening panel of the housing 101, the louver arrangement 110 comprises a plurality of interlinked shielding plates 110a supported by a motorized cascading slider unit 110b, a plurality of nozzles 111 connected with a box 112 provided with the housing 101, a Peltier unit 113 is provided within the food chamber 106, a plurality of air blowers 114 provided inside the housing 101.

[0024] The device disclosed herein includes a housing 101 to receive and hold student’s belongings. The housing 101 herein includes all necessary component of the device for handling and managing items autonomously. In an embodiment of the present invention, the housing 101 is cuboidal in shape inherently contributes to its structural stability and ease of placement, offering a robust and practical design for the device.

[0025] A push button is equipped with the device and installed on the housing 101 for activating and deactivating the device. The push button is accessed by a user for activating the device. When the user presses the push button, the electrical circuit is completed, which in response turns the device on. The push button is integrated with an actuator and a spring, which are automatically activated when pressed. They work together to move the internal contact, completing the circuit and allowing electrical current to flow, thereby activating the device.

[0026] When the push button is pressed, the button sends a signal (usually a change in voltage or current) to an inbuilt microcontroller associated with the device to either power up or shut down the microcontroller. Conversely, releasing the button allows the spring to return to its original position, breaking the circuit and sending the signal to deactivate the device. The microcontroller is pre-fed to detect this signal and respond accordingly. The microcontroller used herein is pre-fed using artificial intelligence and machine learning protocols to coordinate the working of the device.

[0027] In an embodiment of the present invention, the user places their bag and other belongings on a platform installed inside the housing to keep the bag and items secured, while the device performs various functions related to safety, security, or monitoring.

[0028] An imaging unit 109 positioned on the exterior of the housing 101 monitors the surroundings and detect unauthorized access or tampering attempts, as well as authenticate students based on emotional expression patterns by using facial recognition protocol. The imaging unit 109 includes an image-capturing module comprising a set of lenses that capture multiple images of the surroundings. The captured images are stored in the memory of the imaging unit 109 as optical data. The imaging unit 109 further comprises a processor fed with artificial intelligence protocols and a facial analysis protocol. This processing involves essential image processing steps such as noise reduction to enhance image clarity, feature extraction to identify relevant characteristics (e.g., shape, color, size), and techniques like segmentation to isolate the student from the background. The extracted and processed data is then converted into digital signals and transmitted to the microcontroller. The microcontroller processes the received data and compare with a profile stored in a linked database. If there is a match, the microcontroller grants access; if not, access is denied.

[0029] A front-facing louver arrangement 110 is mounted over an opening panel of the housing 101 to slide into position and lock the panel when tampering is detected. The arrangement 110 consists of multiple interlinked shielding plates 110a supported by a motorized cascading slider unit 110b, which is actuated in response to tampering signals. Upon activation, the shielding plates 110a move into place to cover and secure the opening panel, effectively preventing unauthorized access.

[0030] The front-facing louver arrangement 110 is a protective measure that consists of multiple interlinked shielding plates 110a that form a flexible barrier, supported by the motorized cascading slider unit 110b. When the imaging unit 109 detects tampering—such as unauthorized handling, forced entry, or abnormal vibrations—a signal is sent to the microcontroller, which activates the motorized slider. The motor drives the cascading slider unit 110b, causing the interlinked plates 110a to slide forward in a sequential manner, covering the opening panel completely. Once in position, the plates 110a lock into place, physically blocking access to the interior of the housing 101. This barrier acts as a first line of defense, preventing further interference while the imaging unit 109 continues to monitor the area for additional threats.

[0031] An L-shaped telescopic link 102 is mounted within the housing 101 via a ball-and-socket joint 103 and equipped with a three-finger gripper 104 designed to unzip bags and retrieve items from the bag. The telescopic link 102 is connected to a pneumatic unit comprising an air compressor, air cylinders, air valves, and a piston, which work in unison to facilitate the extension and retraction of the link 102. The pneumatic unit is controlled by the microcontroller, which actuates the valves to allow compressed air from the compressor into the cylinders. The compressed air generates pressure against the piston, causing it to push and extend the telescopic arm. The piston is mechanically linked to the telescopic link 102, and the applied pressure results in the extension of the arm. Similarly, the microcontroller retracts the telescopic link 102 by closing the valve, releasing the compressed air and allowing the piston to retract. Thus, the microcontroller precisely regulates the extension and retraction of the telescopic link 102 to accurately position the gripper 104 for unzipping bags and retrieving items.

[0032] The three-finger gripper 104 is designed for versatile item handling, capable of selectively managing a range of objects from fragile items to perishable goods. This is achieved through its adjustable grip pressure, precisely controlled by the microcontroller. The three-finger gripper 104 operates by coordinating the movement of its three articulated fingers to grasp, hold, and manipulating the zipper pull tab and securely grasping items within the bag. Each finger moves independently or in unison, allowing the gripper 104 to conform to various shapes and sizes of items. The fingers are typically actuated by motors that control their opening and closing, with adjustable grip force to handle both fragile and sturdy objects securely. For unzipping the bags, the gripper’s fingers first close around the zipper pull tab, applying sufficient force to hold it firmly without slipping. Then, coordinated motion from the gripper 104 and telescopic link 102 pulls the zipper along its track to open the bag smoothly. After unzipping, the gripper 104 carefully extends its fingers into the bag to locate and gently grasp the desired item, which it then retracts safely out of the bag.

[0033] The ball and socket joint 103 includes a motor powered by the microcontroller generating electrical current, a ball shaped element and a socket. The ball moves freely within the socket. The motor rotates the ball in various directions that is controlled by the microcontroller that further commands the motor to position the ball precisely. The microcontroller further actuates the motor to generate electrical current to rotate in the joint 103 for providing movement to the link 102 for accurate positioning and manipulation.

[0034] A camera 105 is positioned inside the housing 101 configured to analyze the contents of bags and detect packaged food items. The camera 105 disclosed herein works in same manner as the imaging unit 109 disclosed above.

[0035] An E-nose (electronic nose) sensor is functionally linked to the gripper 104 to detect cooked food, especially indicates that the food might spoil or deteriorate if exposed to a heated environment. The E-nose sensor detects cooked food identify specific volatile organic compounds (VOCs) emitted by food items. The sensor consists of an array of chemical sensors that react to different odor molecules present in the environment. When the gripper 104 moves near or inside the bag, the E-nose samples the air and captures the unique chemical signatures released by cooked food. These sensor responses generate electrical signals that are processed by embedded artificial intelligence protocols to recognize the characteristic scent patterns of cooked food. Once identified, this information is transmitted to the microcontroller, which then triggers the telescopic link 102 and gripper 104 to transfer the detected cooked food into a dedicated food chamber 106 provided within the housing 101 for storage.

[0036] A Peltier unit 113 works with a temperature sensor in the food chamber 106 to keep food fresh by controlling its temperature. Firstly, the temperature sensor sense the temperature inside the chamber 106 and it is composed of metal that generate an electrical voltage or resistance when experienced to temperature changes. The senor works by measuring the voltage across the diode terminals. The resistance of the diode is detected and transformed into readable values in order to measure the temperature inside of the chamber 106. The measured temperature is then converted into electrical signal which is received by the microcontroller. The microcontroller further processes the measured temperature and in case detected temperature matches a pre-fed temperature stored in the linked database as detected via the microcontroller.

[0037] If the detected temperature within the food chamber 106 exceeds or recedes from the pre-set optimal temperature, the microcontroller activates the Peltier unit 113 to regulate it, ensuring food remains fresh. The Peltier unit 113 itself consists of two semiconductor plates (Peltier plates) connected in series and sandwiched between two ceramic plates. When an electric current is applied to the Peltier unit 113, heat is either absorbed or released, depending on the direction of the current flow. Thereby, it effectively transfers heat from one side to the other, either cooling or warming the food chamber 106 as needed to maintain the desired temperature.

[0038] A movable slider 107 is positioned above the base of the housing 101, carrying an inspection unit 108 installed on the slider 107 to detect metallic and/or contraband objects and identify illicit substances. The slider 107 comprises a motorized carriage mounted on a rail, enabling controlled linear movement of the inspection unit 108. Upon actuation by the microcontroller, the motor drives the carriage along the rail, facilitating smooth and precise sliding motion of the inspection unit 108 across the interior of the housing 101 for comprehensive scanning and analysis.

[0039] The inspection unit 108 comprises an X-ray camera and a chemical sensor, to detect metallic and/or contraband objects and to identify illicit substances. The inspection unit 108 operates through the combined functionality of the X-ray camera and a chemical sensor to detect concealed metallic or contraband items and identify illicit substances. The X-ray camera emits controlled X-ray radiation that penetrates the contents of bags or items placed within the housing 101. As the rays pass through various materials, they are absorbed at different rates depending on the material's density and composition. The resulting image, captured by the X-ray detector, reveals internal structures and highlights the presence of metallic objects, hidden compartments, or unusual shapes associated with contraband. Simultaneously, the chemical sensor samples the air around or within the item using a sensitive detection array capable of identifying trace chemicals or vapors. These include drug residues, explosives, or other illicit substances. The sensor data and X-ray images are processed by the microcontroller using pattern recognition and substance matching protocols to cross-reference physical and chemical signatures for ensuring accurate detection and reducing false positives. Once identified, the microcontroller generates an alert on a computing unit of the user or restrict further handling of the suspicious item.

[0040] In an embodiment of the present invention, a communication module is linked with the microcontroller and activated for establishing a wireless connection between the microcontroller and the computing unit (includes, but not limited to smartphone, tablet or laptop) and inbuilt with a user-interface that is accessed by the user, for alerting the user regarding the detected metallic and/or contraband objects and identifying illicit substances.

[0041] The communication module used herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used herein is preferably a Wi-Fi module that is a hardware component that enables the microcontroller to connect wirelessly with the computing unit. The Wi-Fi module works by utilizing radio waves to transmit and receive data over short distances. The core functionality relies on the IEEE 802.11 standards, which define the protocols for wireless local area networking (WLAN). Once connected, the module allows the microcontroller to send and receive data through data packets.

[0042] The user interface features a scheduling module that lets students upload and manage their academic lecture schedules, whether by manually inputting class times and course details, or potentially by importing a digital timetable file. Once uploaded, these schedules are automatically synchronized with the microcontroller. The microcontroller processes the schedule data, cross-referencing it with the database of the student's stored books and materials. Based on upcoming lectures, the microcontroller identifies and prepares the required items. For example, if a student has a chemistry lecture scheduled for the next morning, the microcontroller directs the telescopic link 102 and gripper 104 to locate and position the relevant chemistry textbook and any associated materials for ensuring they are ready for easy retrieval or delivery at the appropriate time.

[0043] A flame sensor is built into the housing 101 to detect fire or excessive heat. The flame sensor operates by identifying the unique electromagnetic radiation emitted during combustion, making it a rapid and accurate fire detection tool. Unlike devices that react to smoke particles or general heat thresholds, flame sensors are designed to detect the specific ultraviolet (UV) and/or infrared (IR) wavelengths produced by flames. These sensors house specialized photodetectors that are highly sensitive to these particular parts of the light spectrum. When a fire occurs, it instantaneously releases UV radiation, which the UV sensors detect for very fast response times. Simultaneously, the flames emit IR radiation in distinct flickering patterns, which IR sensors identify. Upon detecting the characteristic radiation signature of a fire, the photodetectors convert this energy into an electrical signal. This signal is then transmitted to the microcontroller to process, and if it matches predefined criteria for a flame stored in the linked database, then the microcontroller, actuates multiple nozzles 111 linked to a box 112 stored with extinguishing agents, and integrated into the housing 101 to release the agents, putting out any detected fires.

[0044] The nozzles 111 operate using electrical energy to precisely control the flow of the extinguishing agent. When activated by the microcontroller, an electric motor or pump significantly pressurizes the incoming extinguishing agent. This conversion of pressure energy into kinetic energy dramatically increases the fluid's velocity, allowing the solution to be sprayed out with high force over the detected fire. The nozzles 111 used herein are dynamically controlled to proportionally release extinguishing agents based on fire severity based on the data received from the flame sensor.

[0045] A second temperature sensor is integrated within the housing 101 to constantly monitor internal heat levels. The second temperature sensor works in same manner as the first temperature sensor disclosed before. If the temperature deviates from the optimal range, then the microcontroller activates a series of air blowers 114 positioned inside the housing 101 to regulate and maintain the desired internal temperature.

[0046] The air blower, consisting of a vortex, heater, impeller, and an outlet duct, plays a crucial role in regulating the internal temperature of the device. When the microcontroller activates the blower, the impeller begins to rotate. This rotation creates a series of vortex motions through its centrifugal movement, drawing air from the device's surroundings. As the drawn air is pushed forward through the impeller's channels, the centrifugal movement generates a helical motion of the air, causing its temperature to increase. Throughout this process, the air is continuously compressed along the channels, leading to a linear increase in pressure. Finally, this pressurized air is transferred from the blower's outlet duct to the internal surfaces of the housing 101, helping to maintain an optimal internal temperature.

[0047] Lastly, a battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0048] The present invention work best in the following manner, where the housing 101 is configured to securely receive and hold students’ belongings. The device includes the L-shaped telescopic link 102 installed via the ball and socket joint 103 within the housing 101, equipped with the three-finger gripper 104 capable of unzipping bags and extracting items, while the camera 105 analyzes bag contents. The E-nose sensor integrated with the gripper 104 detects cooked food and enables transfer to the dedicated food chamber 106. The food chamber 106 is temperature-regulated using the Peltier unit 113 controlled by the first temperature sensor to maintain freshness. Once the bag is opened, the movable slider 107 moves the inspection unit 108, which includes the X-ray camera and chemical sensor, to detect metallic, contraband, or illicit items. The imaging unit 109 monitors surroundings, detects unauthorized access or tampering, and operates in conjunction with the facial recognition protocol to authenticate students based on emotional expression. Upon tampering detection, the microcontroller activates the front-facing louver assembly comprising interlinked shielding plates 110a supported by the motorized cascading slider unit 110b to lock the opening panel. The flame sensor detects fire or elevated heat, and the second temperature sensor monitors internal heat levels in real time. In response, the plurality of nozzles 111 connected to the extinguishing agent box 112 dynamically release the agents based on fire severity, while the air blowers 114 regulate internal temperature. The user-interface integrated into the computing unit allows manual override, real-time alerts, and schedule management synchronized with the microcontroller to automate sorting and delivery of academic materials.

[0049] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
