DETAILED DESCRIPTION OF THE INVENTION

[0018] 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.

[0019] 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.

[0020] 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.

[0021] The present invention relates to a back mounted goods carrying device that is accessed by a user for storing and carrying essential goods by dynamically adjusting the storage space, based on the quantity and size of stored items, while also providing automated security features and personalized ergonomic adjustments for enhanced user comfort and convenience.

[0022] Referring to Figure 1 and 2, an isometric view of a back mounted goods carrying device and an inner view of the proposed device are illustrated, respectively, comprising an enclosure 101 having a chamber 201 a plurality of inverted U-shaped extendable frames 202 installed vertically within the chamber 201 by means of telescopic rods 203, a cuboidal cushioned chamber 108 provided in the enclosure 101, a cylindrical cushioned compartment 109 attached with the enclosure 101, a receptacle 208 within the enclosure 101 having a plurality of elongated tubular recesses 206 configured with iris lids 207, a zipper fastener 102 provided at an opening of the enclosure 101, a pair of straps 103, each having a plurality of links 204 connected by hinges 205, an artificial intelligence-based imaging unit 104, installed on the enclosure 101, each of the frames 202 is configured with a drawer mechanism 209, a biometric sensor 105 provided on the enclosure 101, a microphone 106 provided on the enclosure 101 and actuate a speaker 107 provided on the enclosure 101.

[0023] The device disclosed herein comprises an enclosure 101 that serves as a main structure of the device and is designed to be accessed by a user to keep books, tiffin box, beverage bottle, and other essential items. The enclosure 101 med of pliable material and integrated with a chamber 201 to store books. When the user places the books inside the chamber 201, an OCR (optical character recognition) module installed in the enclosure 101 to capture names of the books and logs them into a connected database for easy retrieval.

[0024] The OCR module identifies and locates text regions using techniques like edge detection, and contour analysis. The OCR module processes the text regions to recognize individual characters and words. After text recognition, the OCR module performs post-processing tasks to correct errors and enhance the accuracy of the recognized text. This basically involves spell-checking, grammar-checking, and resolving ambiguities and store all information into the connected database for easy retrieval.

[0025] The chamber 201 is segregated into multiple slots by means of a plurality of inverted U-shaped extendable frames 202. The frames 202 are vertically installed within the chamber 201 via telescopic rods 203, wherein each of the frames 202 is configured with a drawer mechanism 209 to adjust height of the frame 202 as per requirement. The drawer mechanism 209 consists of a drawer that typically slides on the rails inside the frame. These rails provide a smooth and stable path for the extensions or retraction of the frame.

[0026] When the microcontroller actuates the drawer mechanism 209, the motor starts rotating and the rotational motion is converted into linear motion through the use of gears. As the motor rotates, the drawer moves either outward or inward along the sliding rails. This extensions or retraction increase or decreases the size of the frame 202 to suit varying storage needs.

[0027] As book are placed inside, multiple pressure sensors, which is embedded in each of the frames 202 to detect the applied force by the stored books. The pressure sensor is strategically positioned within the frames 202 to accurately detect the intensity of the impact during collision of the books and the frame. When a collision occurs, the pressure sensor measures the force applied by the books. The data from the pressure sensor is transmitted to a microcontroller which processes the information in real time and detect the applied force by the stored books.

[0028] If the detected pressure exceeds the predefined threshold, the microcontroller actuates the rods 203 and frames 202 to retract. The telescopic rods 203 as mentioned herein are powered by a pneumatic unit that utilizes compressed air to extend and retract the rods 203. The process begins with an air compressor which compresses atmospheric air to a higher pressure. The air cylinder of the pneumatic unit contains a piston that moves back and forth within the cylinder. The cylinder is connected to one end of the telescopic rods 203. The piston is attached to the telescopically operated rods 203 and its movement is controlled by the flow of compressed air. To retract the telescopic rods 203, the piston activates the air valve to allow compressed air to flow into the chamber behind the piston. As the pressure increases in the chamber, the piston pulls the telescopic rods 203 to the desired length.

[0029] This adjustment maximizes the available space within the chamber 201, preventing overcrowding and optimizing organization. In parallel, if the user has preset the list of essential books to carry, the microcontroller compares the logged book names with the input list. If any required book is missing, a speaker 107 embedded in the enclosure 101 emits the alert to notify the user. The speaker 107 is capable of producing clear and natural sound and is capable of adjusting its volume based on ambient noise levels.

[0030] The speaker 107 consists of audio information, which is in the form of recorded voice, synthesized voice, or other sounds, generated or stored as digital data. This data is often in the form of an audio file. The digital audio data is sent to a digital-to-analog converter (DAC). The DAC converts the digital data into analog electrical signals. The analog signal is often weak and needs to be amplified. An amplifier boosts the strength to a level so that the speaker 107 drives it effectively. The amplified audio signal is then sent to the speaker 107. The core of the speaker 107 is an electromagnet attached to a flexible cone. These sound waves travel through the air as pressure waves and are picked by the user’s ear.

[0031] To cater to food and beverage storage, the enclosure 101 integrates a cuboidal cushioned chamber 108 specifically for storing the tiffin box and a cylindrical cushioned compartment 109 for holding the beverage bottle. Both the chamber 108 and compartment 109 is embedded with a first and second temperature sensors that continuously monitors internal temperature levels. The core component of the first and second temperature sensors is the sensing element which may include but is not limited to thermistors, thermocouples, or resistance detectors. The sensing element detects temperature changes in the tiffin box and bottle by altering its electrical properties. As the temperature increases and decreases, the resistance of the sensing element changes accordingly. The microcontroller continuously monitors the data from the first and second temperature sensors and compares the monitored temperature with a threshold temperature.

[0032] Both the chamber 108 and compartment 109 is embedded with a first and second Peltier unit (first for the tiffin box and second for the beverage bottle). If the temperature deviates from the predefined range, the corresponding Peltier unit (first for the tiffin box and second for the beverage bottle) is activated to regulate the temperature and maintain the desired thermal conditions. The Peltier unit is a thermoelectric cooler that uses the Peltier effect to transfer heat from one side of the unit to the other when an electrical current is passed.

[0033] The Peltier unit consists of two semiconductor materials connected in a sandwich-like fashion. These materials are typically made of bismuth telluride and one side of the Peltier unit is called the hot side and the other is the cold side. When a direct current is applied to the Peltier unit, electrodes within the semiconductor material start moving from one side to the other. The Peltier effect occurs as a result of electron movement. When electrons flow from the cold side to the hot side, they carry heat with them. This leads to one side of the Peltier unit becoming colder, and the other side becoming hooter. This effect allows the Peltier unit to effectively transfer heat from one side to the other, creating a temperature gradient. Additionally, both the chamber 108 and compartment 109 are lined with the air cushion connected to inflation units, ensuring that the stored items remain securely gripped and protected from external shocks.

[0034] For securing the stored items, the enclosure 101 is equipped with a zipper fastener 102 at its opening, wherein a pull tab of the fastener 102 is configured with the electromagnet, which attaches to the metallic end at the opening, effectively locking the enclosure 101 when in the closed position. The electromagnet consists of a core material typically made of iron or steel wrapped with an insulated wire. The wire is coiled around the core to form a solenoid. The electromagnet is connected to a power source, usually a battery or a low-voltage power supply. When an electric current flows through the wire, it creates a magnetic field around the solenoid. The direction of the magnetic field depends on the direction of the current flow and as the electromagnets activates, the metallic end attached with the opening, thereby effectively locking the enclosure 101 when in the closed position.

[0035] To access the stored contents, the user must authenticate themselves using a biometric sensor 105 embedded on the enclosure 101. The biometric sensor 105 mentioned herein is typically the fingerprint sensor captures the user’s unique physiological or behavioral characteristics and converts them into a digital template. This template is a mathematical representation of the fingerprints. The digital template is compared to the pre-saved fingerprints stored in the database for the verification of the user. This is done by calculating the similarity between the new templates and the stored templates. There’s a matching threshold set to determine whether the captured fingerprint sufficiently matches any of the pre-saved fingerprints. A receptacle 208 within the enclosure 101 having a plurality of elongated tubular recesses 206 configured with iris lids 207 for a secure storage of stationary items.

[0036] Based on the comparison results and the matching threshold of the fingerprints the authentication is decided. Upon successful authentication, the electromagnet is deactivated, unlocking the opening and allowing access to the chamber 201. A pair of straps 103 having multiple links 204 and connected with the help of hinges 205 encased in the fabric sheath, are attached to the rear surface of the enclosure 101 through sliding units.

[0037] An artificial intelligence-based imaging unit 104, in synchronization with the ultrasonic sensor, scans and records the user’s dimensions. The artificial intelligence based imaging unit 104 is constructed with a camera lens and a processor, wherein the camera lens is adapted to capture a series of images in vicinity of the enclosure 101. The processor carries out a sequence of image processing operations including pre-processing, feature extraction, and classification by utilizing machine learning and artificial intelligence protocols. The image captured by the imaging unit 104 is real-time images of the enclosure’s 101 surrounding. The artificial intelligence based imaging unit 104 transmits the captured image signal in the form of digital bits to the microcontroller. The microcontroller upon receiving the image signals compares the received image signal with the pre-fed data stored in a database and constantly determines dimensions of the user.

[0038] The microcontroller then actuates the sliding units and hinges 205, automatically adjusting the curvature and positioning of the straps 103 for the custom fit according to the user’s body structure. The sliding unit consists of a motor, and a rail unit integrated with ball bearings to allow smooth linear movement. As the motor rotates the rotational motion of the motor is converted into linear motion through a pair of belts and linkages. This linear motion provides a stable track and allows the translation of the straps 103 for the custom fit according to the user’s body structure.

[0039] Additionally, an accelerometer embedded in the enclosure 101 detects motion and adjusts the straps 103 in real-time to maintain stability, minimizing shaking while in transit. The accelerometers work by measuring acceleration or changes in velocity. They consist of microelectromechanical systems (MEMS) to detect and measure acceleration. These sensors are incredibly small and sensitive, allowing them to accurately capture even the slightest vibrations. When the accelerometers detect the changes in acceleration and provide data on the intensity and frequency of the vibrations.

[0040] To enhance user convenience, the enclosure 101 integrates a microphone 106 that allows voice command input. If the user needs to adjust the straps 103 manually, they need to issue the voice command over the microphone 106, which plays a crucial role by converting spoken words or commands into electrical signals which are then processed and analyzed to trigger specific actions. When the user speaks or commands, their vocal cords vibrate, creating sound waves. These sound waves travel through the air as variations in air pressure. The microphone 106 mentioned herein is a transducer that converts these variations in air into electric signals. The analog electrical signal is converted into digital form which is done by an analog-to-digital converter (ADC). The digital signal is then subjected to various signal processing techniques to enhance voice quality and eliminate noise. The microcontroller then converts the signal into specific commands and prompting the imaging unit 104 and ultrasonic sensor to reassess the user’s dimensions and make necessary adjustments.

[0041] Furthermore, a GPS (Global Positioning System) unit installed with the microcontroller, which remotely activated through a user interface installed on the user’s computing unit to enable real-time location tracking of the enclosure 101. The GPS unit consists of a receiver that communicates with the satellites to determine the exact location of the enclosure 101. The GPS unit constantly receives signals from the satellites and calculates the coordinates. The GPS unit works by receiving signals from multiple satellites orbiting the Earth. The GPS unit uses the timing of these signals and trilateration to calculate the precise location of the enclosure 101. The microcontroller linked with the GPS unit processes the data received from the GPS unit and transmits the enclosure’s 101 precise location data including the latitude and the longitude to the enclosure 101. The real-time location coordinates of the enclosure 101 are then sent to the microcontroller, thereby ensuring its security and allowing the user to retrieve its location if misplaced.

[0042] A battery 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.

[0043] The present invention works best in the following manner, where the enclosure 101 as disclosed in the invention is made from the pliable material that accommodates books, the tiffin box, the beverage bottle, and other essential items. When the user places books inside the chamber 201, the OCR (optical character recognition) module captures the names of the stored books and logs them into the connected database for easy retrieval. The chamber 201 is divided into multiple slots using inverted U-shaped extendable frames 202 installed vertically with telescopic rods 203. These frames 202 help in organizing books and adjust in height using the drawer mechanism 209 to suit varying storage needs. As books are placed inside, the pressure sensors embedded within the frames 202 detect the applied force. If the detected pressure exceeds the predefined threshold, the microcontroller is triggered to actuate the telescopic rods 203, prompting the frames 202 to retract. This dynamic adjustment maximizes the available space within the chamber 201, preventing overcrowding and optimizing organization. In parallel, if the user has preset the list of essential books to carry, the microcontroller compares the logged book names with the input list. If any required book is missing, the speaker 107 embedded in the enclosure 101 emits the alert to notify the user. To cater to food and beverage storage, the enclosure 101 integrates the cuboidal cushioned chamber 108 specifically for storing the tiffin box and the cylindrical cushioned compartment 109 for holding the beverage bottle. Each storage section is embedded with the first and second temperature sensors that continuously monitors internal temperature levels. If the temperature deviates from the predefined range, the corresponding Peltier unit (first for the tiffin box and second for the beverage bottle) is activated to regulate the temperature and maintain the desired thermal conditions. Additionally, both the chamber 108 and compartment 109 are lined with the air cushion connected to inflation units, ensuring that the stored items remain securely gripped and protected from external shocks. For securing the stored items, the enclosure 101 is equipped with the zipper fastener 102 at its opening.

[0044] In continuation, the pull tab of this fastener 102 is configured with the electromagnet, which attaches to the metallic end at the opening, effectively locking the enclosure 101 when in the closed position. To access the stored contents, the user must authenticate themselves using the biometric sensor 105 embedded on the enclosure 101. Upon successful authentication, the electromagnet is deactivated, unlocking the opening and allowing access to the chamber 201. The pair of adjustable straps 103, consisting of multiple links 204 connected by hinges 205 encased in the fabric sheath, are attached to the rear surface of the enclosure 101 through sliding units. The artificial intelligence-based imaging unit 104, in synchronization with the ultrasonic sensor, scans and records the user’s dimensions. The microcontroller then actuates the sliding units and hinges 205, automatically adjusting the curvature and positioning of the straps 103 for the custom fit according to the user’s body structure. Additionally, the accelerometer embedded in the enclosure 101 detects motion and adjusts the straps 103 in real-time to maintain stability, minimizing shaking while in transit. To enhance user convenience, the enclosure 101 integrates the microphone 106 that allows voice command input. If the user needs to adjust the straps 103 manually, they need to issue the voice command, prompting the imaging unit 104 and ultrasonic sensor to reassess the user’s dimensions and make necessary adjustments. Furthermore, the GPS unit remotely activated through the user interface installed on the user’s computing unit. This feature enables real-time location tracking of the enclosure 101, ensuring its security and allowing the user to retrieve its location if misplaced.
