Specification

Description:FIELD OF THE INVENTION

[0001] The present invention relates to an automated door operating device that is capable of opening and closing of the door in an automated manner, thus allowing only authorized user to enter in an enclosure.

BACKGROUND OF THE INVENTION

[0002] The entrance or exit to a room, building, or any other enclosed space is often secured by installing a door over it. The door serves several functions, including providing privacy, security, and controlling the flow of people, air, and light between different areas. Mostly the doors are hinged to the wall and is opened and closed for different purposes. In corporate building or places where mobility of people is frequent through the doors. People with different conditions like disabilities, mobility issues, carrying heavy items, or women carrying their child use the door to enter and exit places like cinema halls, shopping malls, and other visiting places, for such people it is inconvenient to open or close the door. Also many people while they exit from the door, left the door open which affect the air conditioning of the enclosed space.

[0003] Traditionally, the doors are operated (opened and closed) by applying a pulling or pushing force over the door manually by the person. Some sliding doors are also used that are opened or closed by horizontally sliding the door along the tracks by pushing the door sideways. In some cases, a door closing mechanism is attached to the top of the door frame that automatically closes the door after it is opened manually. The locking of the door is performed manually by using different types of door locks installed to the door frame, in some traditional doors, a normal lock and key is also used to lock the handle of the door. While these traditional methods offer some benefits, but they also pose several challenges and drawbacks. Some individuals, preferably those with disabilities or whose both hands are engaged, may find it challenging to operate traditional doors. User need to set down the belongings they are carrying in order to operate the door. Also human error or negligence might result in doors being left open unintentionally, compromising security by allowing unauthorized access or creating opportunities for theft or intrusion.

[0004] US10612289B2 discloses about an automated door-opening device that includes a first sensor disposed on the outside of the door. The first sensor is adapted to recognize a predetermined pattern of a gesture made by a patron. The gesture made in front of the first sensor opens the door by a first actuator. A second actuator can be used to lock or unlock the door, thereby providing full hand-free operation of the door. A hinge system is disclosed that includes three off-set hinges adapted to utilize the weight of the door to cause the door to self-position and allow manual operation of the door. Although US'289 discloses about an invention that relates to an apparatus for automatically opening, closing, locking, and unlocking a door and more specifically for hands-free operation of a door. The invention also relates to a hinge mechanism apparatus for automated doors and more specifically, to a hinge mechanism for hands-free operation of a door. However, the cited invention lacks in opening and closing the door by proper facial authentication of the user in proximity to the door.

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. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[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 an automated door operating device that is capable of locking a door as well as performing opening and closing of the door in an automated manner by authenticating the person in proximity to the door. Additionally, the proposed device is capable of detecting an impact force applied over the door by any intruder and accordingly notifies a concerned authority regarding an unauthorized entry attempt.

[0022] Referring to Figure 1 and Figure 2, an isometric view of an automated door operating device and a rear view of an automated door operating device are illustrated, respectively comprising an elongated body 101 affixed over a door jamb by means of plurality of primary suction units 201, an artificial intelligence based imaging unit 102 installed over the body 101, a motorized sliding unit 103 installed over the body 101, plurality of telescopic rods 104 configured with the sliding unit 103, a secondary suction unit 105 installed with each of the rod, and a motorized hinge joint 106 installed between each of the rods 104 and the sliding unit 103.

[0023] The device disclosed herein comprises of an elongated body 101 that is affixed over a door jamb by means of plurality of primary suction units 201 ranging from six to ten in numbers and positioned at inner side of the door. The suction unit 201 includes a suction cup that provides an additional grip to the body. On actuation by an inbuilt microcontroller, the suction unit 201 creates an airtight between the cup's flexible rim and the door jamb, for sealing off the area within the suction cup. The flexible rim of the suction cup is designed to maintain an airtight seal between the cup and the door jamb. The suction cup used herein are made up of silicone rubber that easily eliminates pressure inside the suction cup for creating a vacuum between the cup and the door jamb in order to affix the body 101 firmly with the door jamb without any slipping or movement.

[0024] Upon affixing the body 101 firmly with the door jamb, the microcontroller activates an artificial intelligence-based imaging unit 102 installed over the body 101 and integrated with a processor for capturing and processing multiple images of the door. The artificial intelligence-based image capturing module comprises of a high-resolution camera lens, digital camera sensor and a processor, wherein the lens captures multiple images of the door from different angles and perspectives with the help of digital camera sensor for providing comprehensive coverage of the door. The captured images then go through pre-processing steps by the processor integrated with the camera. The processor carries out a sequence of image processing operation including pre-processing, feature extraction and classification in order to enhance the image quality, which includes adjusting brightness and contrast and removing any distortion or noise. The pre-processed images are then transmitted to the microcontroller linked with the processor, in the form of electrical signals.

[0025] The microcontroller further processes the received signals in order to determine length and breadth of the door. Based on the determined length of the door, the microcontroller actuates a motorized sliding unit 103 installed over the body 101 to provide translation to multiple telescopic rods 104 ranging from three to five in numbers configured with the sliding unit 103. The motorized sliding unit 103 used herein consists of a sliding-rail and multiple rolling members which are integrated with a step motor. On actuation the step motor rotates the rolling members in order to provide rolling motion to the members which results in sliding of the telescopic rods 104 along with the members and position the rods 104 equidistantly over the sliding unit 103 in accordance with the length of the door.

[0026] After the telescopic rods 104 are positioned at equal distance, the microcontroller actuates the telescopic rods 104 to extend as per the detected breadth of the door. The extension of the telescopic rod is powered by a pneumatic unit associated with the device that includes an air compressor, air valves, and a piston. The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor is consisting of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure.

[0027] The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend which extends the rods 104 in order to position a secondary suction unit 105 installed with each of the rod in contact with the stile of the door. The stile is a part of the door that runs vertically along the outside edge of the door and serves as a hard surface for the attachment of hinges, locks, and other hardware to the door.

[0028] Upon positioning of the secondary suction units 105 in contact with the stile of the door, the microcontroller actuates the secondary suction units 105 to grip the stile in a secured manner. The secondary suction unit 105 work on the same principle as that the primary suction unit 105 discloses above, thus the secondary suction unit 105 grip the stile in a secured manner. After the telescopic rods 104 securely grip the stile of the door, the microcontroller activates a facial recognition module integrated with the microcontroller to work in sync with the imaging unit 102 for capturing multiple images of the user approaching the door and detecting facial features, such as eyes, nose, and mouth, and then create a unique facial template according to the determined facial features of the user, the created facial template is further matched by the microcontroller with a pre-saved facial features/templates of registered users stored in a database associated with the microcontroller in view of authentication of the user.

[0029] Upon successful authentication of the user, the microcontroller actuates a motorized hinge joint 106 installed between each of the rods 104 and the sliding unit 103 to provide rotation to the rods 104 in a synchronized manner for applying a pulling force over the door in view of opening the door. The hinge is a piece of metal that interconnects the rods 104 with the sliding unit 103 and allows the rods 104 to apply a pulling force over the door by revolving the rods 104 along the longitudinal axis whose operation is governed by a bi-directional direct current motor that is linked with the microcontroller.

[0030] The bi-directional direct current motor is capable of converting direct current into mechanical work by following the principle of Lorentz Law which states that, the current carrying conduction when placed in magnetic or electrical field experiences a force known as Lorentz force. Such that the motor converts the electrical current derived from an external source into a mechanical torque for providing the required power to the hinges to rotate the rods 104.

[0031] When the motor rotates, then provides movement to the hinges followed by which the telescopic rods 104 also rotates and apply a pulling force over the door in order to open the door. Also in case of unsuccessful authentication of the user, the microcontroller directs the hinge joints 106 to rotate in a reverse direction to apply a pushing force over the door in view of restrict opening of the door. An impact sensor is installed over each of the rods 104 to experience an impact force applied by any intruder.

[0032] The impact sensor disclosed herein is a piece of electronic equipment that detects an impact through vibrations in a manner when the surfaces of the sensor experiences a sudden impact the vibrations are imparted which are converted to suitable output signals and sent to the microcontroller in the form of electrical signals. The microcontroller processes the received signals to detect the impact applied over the door by any intruder and simultaneously directs the hinge joints 106 to apply a pushing force over the door in view of restrict opening of the door.

[0033] Upon detection of any impact over the door, the microcontroller activates a force intensity meter installed over each of the telescopic rods 104 to monitor force applied by the intruder while attempting to open the door. The force intensity meter consists of a sensor element that is responsible for detecting the magnitude of the applied force over the door. The sensor element works on the principle of piezoelectric sensor that generate an electric charge according to the magnitude of the detected force. The generated electric charge is converted into a measurable signal, such as an electrical voltage or current and sent to the linked microcontroller for further processing.

[0034] The microcontroller processes the received signal in order to determine the intensity of the force applied over the door by the intruder, and in case the monitored force exceeds a threshold level, the microcontroller sends an alert notification to a computing unit accessed by a concerned authority, by means of a Wi-Fi based communication module integrated with the microcontroller, in order to inform the user regarding the unauthorized entry attempt.

[0035] The communication module employed herein acts as an intermediate between various electronic components, wherein the module is used to establish the communication between the concerned person's computing unit and the microcontroller. The Wi-Fi based communication module is designed for establishing a wireless connection between computing unit and the microcontroller. This module is able to receive serial data from radiation monitoring devices such as computing unit and transmit the data to the microcontroller.

[0036] Moreover, 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.

[0037] The proposed invention works well in the following manner, where the elongated body 101 is affixed over the door jamb via multiple primary suction units 201 and positioned at inner side of the door. The imaging unit 102 determines length and breadth of the door. Based on the length of the door, the motorized sliding unit 103 provide translation to multiple telescopic rods 104. After that the microcontroller actuates the rods 104 in order to position the secondary suction unit 105 in contact with the stile of the door to grip the stile in a secured manner. The facial recognition module determines facial features of any user approaching the door. The microcontroller matches the determined facial features with the pre-saved facial features of registered users stored in the database. In case of successful authentication of the user, the microcontroller actuates the motorized hinge joints 106 to apply a pulling force over the door for opening the door and in case of unsuccessful authentication of the user, the hinge joints 106 apply a pushing force over the door to restrict opening of the door. The impact sensor experience an impact force applied by any intruder, and upon detection of the impact, the microcontroller directs the hinge joints 106 to apply a pushing force over the door to restrict opening of the door. Further the force intensity meter monitor force applied by the intruder while attempting to open the door, and in case the monitored force exceeds threshold level, an alert notification is sent via the communication module to the computing unit accessed by the concerned authority, in order to inform regarding the unauthorized entry attempt.

[0038] 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.
