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 adjustable security device that is capable of allowing an only authorized user to enter in an enclosure by means of verifying the biometric identity of the user, thus preventing unauthorized user to enter in the enclosure. Moreover, the device is also capable of being adjusted in accordance with the height of the user for allowing the user to input biometric impression before entering in the enclosure.

[0022] Referring to Figure 1, an isometric view of adjustable security device illustrates as, a vertical elongated plate 101 developed to be fixed on a wall, an artificial intelligence based imaging unit 102 installed on the plate 101, a motorized slider 103 arranged on the plate 101, a cuboidal body 104 positioned on the slider 103 upward/downward, a finger scanner 105 configured in the body 104, a LED 106 light configured on the body 104, a display panel 107 installed on the body 104, a buzzer 108 housed in the body 104.

[0023] The device includes a vertical elongated plate 101 designed for mounting on wall adjacent to the door of an enclosure. The plate 101 serves as the interface for the user to initiate the authentication process. The plate 101 is integrated with a push button which is strategically positioned for easy access by user. Upon pressing of the button, the circuits get closed allowing conduction of electricity that leads to activation of the device and vice versa. After switching on the device by the user, the microcontroller generates a command to actuate the security device.

[0024] The device is equipped with an inbuilt microcontroller that is directly linked to the push button integrated into the vertical elongated plate 101. Upon activation by the user, this microcontroller triggers an artificial intelligence-based imaging unit 102, which includes a processor, also installed on the plate 101. The imaging unit 102 captures and processes images of the user standing in front of the device, specifically to determine the user's height. The imaging unit 102 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the user present in front of the device and the captured images are stored within memory of the imaging unit 102 in form of an optical data. The imaging unit 102 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines height of the user standing Infront of the device.

[0025] Once the height is determined, the microcontroller actuates a motorized slider 103 mechanism that is arranged on the plate 101. This slider 103 is responsible for moving a cuboidal body 104, which is positioned on the slider 103, either upward or downward. The cuboidal body 104 is made up of any material but not limited to plastic, metal alike material. The motorized slider 103 typically consists of a motorized carriage attached to a rail, which enables controlled linear movement of the links along with a bar towards the sides of the plate 101. Upon actuation by the microcontroller, the motor drives the carriage along the rail, facilitating smooth and precise sliding motion of the cuboidal body 104 along with the bar towards the side of the plate 101.

[0026] The device features a fingerprint scanner integrated within the cuboidal body 104 positioned on the motorized slider 103. The finger scanner 105 is configured to be easily accessed by the user, allowing them to provide their fingerprint impressions. These impressions are then compared against a plurality of pre-stored fingerprint patterns stored in a database linked to the microcontroller. Upon a successful match between the user's fingerprint impression and the pre-stored patterns, the microcontroller triggers an LED 106 (light-emitting diode) light, also configured on the cuboidal body 104, to emit a green light. The LED 106 is a two-lead semiconductor light source also known as p-n junction which produce the lighting when constant voltage is supplied across the diode. When the voltage is supplied across the diode, the electrons recombine with the electrons hole in the diode which result in conversion of electron into photons which is another form of light.

[0027] This green illumination serves as a visual notification to the user, indicating that authentication has been successful. Following the successful authentication, the microcontroller generates a corresponding command to initiate the opening of the door to the enclosure, thereby granting the user entry or exit from the secured area.

[0028] The body 104 have a feature to handle unsuccessful authentication attempts. In such cases, the microcontroller activates the LED 106 light, which is integrated into the body 104, to emit a red light. The red illumination serves as an immediate visual indicator of the failed authentication. Following this, the microcontroller triggers a buzzer 108, also housed within the body 104, to emit an alerting sound. The buzzer 108's sound is designed to notify concerned individuals or security personnel of the unauthorized attempt to access the enclosure. This dual alert device combining both visual and audible cues ensures that any unauthorized access attempt is promptly and effectively communicated, thereby enhancing the overall security provided by the device.

[0029] Upon unsuccessful authentication is detected, the microcontroller triggers the imaging unit 102, which is integrated into the device, to capture images of the user. These images are then stored in the device's database, which is linked to the microcontroller. The captured images provide a visual record of the individual attempting unauthorized access, allowing for further investigation and review by security personnel. The feature enhances the security capabilities of the device by not only deterring unauthorized access but also by creating a documented trail that is used for subsequent analysis and identification.

[0030] The scanner is fabricated with a temperature sensor which is based on infrared. The sensor is designed to measure the user's body 104 temperature during their interaction with the device. As the user places their finger on the scanner for authentication, the infrared sensor simultaneously records the temperature. The recorded temperature is then transmitted to the microcontroller, which displays the temperature reading on a display panel 107 installed on the body 104. The functionality not only provides an additional layer of health monitoring but also integrates seamlessly into the user authentication process, ensuring that the device tracks and display critical information in real-time.

[0031] A timer module is responsible for accurately recording the exact time of the user’s entrance and exit from the enclosure. The timer module is integrated with the microcontroller. When the user interacts with the device by pressing the push button and undergoing fingerprint authentication, the timer module automatically records the time at which these actions occur. The precise time-stamping function is crucial for logging the user’s activity, ensuring that the device maintains an accurate record of entry and exit times. The integration of the timer module into the microcontroller allows for seamless operation, enabling the device to efficiently track and document the timing of user interactions without requiring any additional user input.

[0032] A display panel 107 installed on the cuboidal body 104 positioned on the motorized slider 103. This display panel 107 is activated by the microcontroller upon successful authentication. The panel serves multiple functions, including displaying the user's identification (ID) and the exact time of their entrance or exit from the enclosure. Additionally, the display panel 107 shows the status of the user, indicating whether they are late or have entered on time. This real-time feedback provided by the display panel 107 ensures that users are immediately informed of their entry status, adding an additional layer of convenience and security to the device.

[0033] The body 104 is integrated with a chamber, which is paired with a nozzle situated near the fingerprint scanner. The chamber is made up of any material but not limited to plastic and metal alike material. The chamber is connected to the nozzle by means of a conduit, allowing the flow of a sanitizing solution. After the user's attendance is recorded, the microcontroller activates a speaker installed on the body 104. This speaker generates audible instructions, notifying the user to remove their finger from the scanner. Following this, the microcontroller actuates the nozzle to spray the sanitizing solution stored in the chamber onto the fingerprint scanner. This process ensures that the scanner is sanitized after each use, thereby maintaining hygiene and reducing the risk of contamination.

[0034] A timer module is responsible for accurately recording the exact time of the user’s entrance and exit from the enclosure. The timer module is integrated with the microcontroller. When the user interacts with the device by pressing the push button and undergoing fingerprint authentication, the timer module automatically records the time at which these actions occur. The precise time-stamping function is crucial for logging the user’s activity, ensuring that the device maintains an accurate record of entry and exit times. The integration of the timer module into the microcontroller allows for seamless operation, enabling the device to efficiently track and document the timing of user interactions without requiring any additional user input.

[0035] Furthermore, the battery (not shown in fig.) is installed with the device to power all electrical and electronic component necessary for their operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate function.

[0036] The proposed device works best in the following manner, the proposed device includes process which begins when the user presses the push button on the plate 101, activating the microcontroller. The microcontroller then triggers the AI-based imaging unit 102 to capture the user’s image and determine their height. Based on this height, the motorized slider 103 adjusts the position of the cuboidal body 104 to ensure the fingerprint scanner is at the optimal height. Once the user places their finger on the scanner, the device captures the fingerprint and compares it with stored patterns in the database. If a match is found, the microcontroller activates the green LED 106, signaling successful authentication. The user’s ID, along with the time of entry or exit, is displayed on the panel, and the door to the enclosure is unlocked. In addition to authentication, the method incorporates hygiene and security measures. After each use, the device instructs the user to remove their finger, followed by the spraying of a sanitizing solution onto the scanner. If the user’s temperature is detected, it is recorded and displayed on the panel. In the case of unsuccessful authentication, the device triggers the red LED 106 and a buzzer 108, while capturing and storing the user’s image for further investigation. The timer module within the microcontroller records all entry and exit times, ensuring a complete and secure log of activity.
