Patent: IN202141002124A
Disclosure: - discloses a method of implanting a distance detection sensor that will give beep sound to the wearer when any object or person comes near to it so the kids get alert that they need to maintain safe distance from others. Once the kids get used to the safe distance scenario then they need not to use the device. This is not only useful for the kids but also can be used by old people or careless elders who least bothers about social distancing. Buzzer and sensor can run on a small battery so that it will be compact to use and makes it fit to be used in any accessory. This method is a cost effective, easy to make and implement module for distance detection and alerting. The circuit consists of a small 3.5 V battery, Arduino Uno chip, HC SRO4 sensor and a buzzer. The circuit can be made and implemented in any of our daily wear accessories so we need not to buy an expensive distance detecting wrist band or such devices. As it is compact and easy to install, we can make sure it to be aesthetically good by our own creative outer covers.
Problem: -
The cited document discloses a wearable band with distance sensing module which can only measure distance and keep the user aware, where the invention has used 3.5 V battery, Arduino Uno chip, HC SRO4 sensor and a buzzer.
Solution: -
The present invention is not a kind of wearable band wherein a 4 in 1 Smart Mask which not only keep the user aware of maintaining social distance but also comes with contactless sanitizing module, body temperature sensor with display, rechargeable battery, and three layers of hepa filtration for smart air filtration. Here we have used 5v lithium polymer battery, buzzer, Arduino uno microcontroller, Mist maker, ultrasonic sensor (HC SR04), body temperature sensor and display, li-po battery charging IC.

The cited document only discloses a wearable band with distance sensing module which can only measure distance and keep the user aware. Whereas the present invention is not a kind of wearable band it’s a 4 in 1 Smart Mask which not only keep the user aware of maintaining social distance but also comes with contactless sanitizing module, body temperature sensor with display, rechargeable battery, and three layers of hepa-filtration for smart air filtration.

The cited document D3 discloses vehicle sanitizing system which sanitize vehicles wheel. Here (PIR) motion sensor and a sanitizing gateway is used. Where vehicles are sanitized when they pass whereas this present invention does not include any vehicle, it is related to bio health where we are sanitizing our hands and our belongings using a contactless sanitizing system present inside the mask. Here the sensor used is an ultrasonic sensor (HC SR04).
Patent: - CN111955824A
Disclosure :- discloses an electronic body temperature mask, which comprises a filter cavity, wherein a temperature sensor, a resistance-voltage conversion module, a microcontroller, a light emitting diode, a detachable rechargeable battery and a button switch which are electrically connected in sequence are arranged on the filter cavity, the temperature sensor is located on the inner side of the filter cavity, and the light emitting diode and the button switch are located on the outer side of the filter cavity. The body temperature measuring method comprises the steps of pressing the button switch to start a power supply; when a user wears the electronic body temperature mask to breathe normally, the temperature sensor measures the body temperature and sends out a resistance signal; the resistance-voltage conversion module converts the resistance signal into a voltage signal and transmits the voltage signal to the microcontroller; the microcontroller processes the voltage signal into a body temperature value and transmits the body temperature value to the light-emitting diode; and the light emitting diode displays the body temperature value. According to the electronic body temperature mask and the body temperature measuring method, viruses can be prevented, the body can be accurately monitored in real time, and the body temperature measuring efficiency is improved.
Problem: -
While both inventions incorporate body temperature monitoring capabilities, our 4-in-1 electronic mask introduces additional functionalities that enhance user safety and convenience. Our device integrates a comprehensive suite of features including a safe distance alert system, contactless sanitizer dispenser, and a triple-layer filtration system, which collectively contribute to mitigating the spread of viruses, including COVID-19.
Solution: -
Moreover, unlike the single-purpose design described in D4, our invention offers a compact and versatile solution by combining multiple functionalities within a single device. The incorporation of an ultrasonic sensor, Arduino UNO microcontroller, buzzer, and sanitizer dispenser significantly expands the capabilities of our electronic mask beyond simple temperature monitoring.
Additionally, our device is designed for practicality and ease of use. It can be powered via USB or a rechargeable battery, providing flexibility for users in various scenarios. The adjustable range and operational parameters further enhance its adaptability to different environments and user preferences.
