Description:FIELD OF THE INVENTION

[0001] The present invention relates to a wearable safety assistive device for mine workers that is designed for providing comprehensive protection to the wearer working in hazardous environments, such as mines, construction sites, or industrial plants, by offering real-time guidance for safe operation within such high-risk areas, thereby ensuring their safety and health.

BACKGROUND OF THE INVENTION

[0002] Mining is a dangerous job where workers are exposed to many risks, such as falling debris, harmful gases, and extreme temperatures. For years, miners have used basic safety helmets and gear to protect themselves. These helmets mainly protect the head from falling objects but don't do much beyond that. Traditional equipment also lacks the ability to track or monitor dangerous environmental conditions, like toxic gases or poor air quality, which are serious risks in mines. In addition, miners have often used simple communication tools, but these are unreliable and limited, especially when immediate help is needed in emergency situations. Because of these shortcomings, workers are still at risk even with the basic safety measures in place. Therefore, there is a need for a more advanced solution that not only protects the workers physically but also provides real-time monitoring and communication to ensure their safety in such a hazardous environment.

[0003] Traditionally, some equipment used by miners for protection while working, like rudimentary helmets made from metal or leather, as these are designed to protect the head from falling debris or rock. These helmets were quite basic and provided limited protection. Over time, miners began to wear more protective gear, such as leather clothing and gloves, to shield themselves from cuts, bruises, and environmental dangers. While these provide better head protection, but these fails to protect workers from toxic gas exposure, temperature extremes, or communication breakdowns in dangerous environments. So, people also use safety lamps, such as the Davy lamp, as these helped miners navigate dark, unsafe environments. However, these lamps were not perfect, and miners still faced risks of gas explosions.

[0004] US4227520A discloses about an invention that includes a miner's safety helmet having a lamp mounted on the front thereof comprising inner and outer shells made of tough, hard plastic material having a generally hemispheric shape to conform with the upper part of the wearer's head, the shells being spaced apart, and closed around the rims thereof, to form an enclosed space therebetween, a slot-like opening at the front part of the rim of the helmet into the enclosed space, a visor of tranparent plastic material rectractably and telescopically mounted in the slot and having a doubly curved shape to conform with the shape of the enclosed space such that when the visor is in a fully retracted position it lies almost completely in the enclosed space and when in fully extended position it extends over the face of the wearer, an air supply connection at the rear of the helmet adapted for connection to a source of clean filtered air, switch means mounted in the helmet in the enclosed space in relation to the visor configuration, and electrical leads from the switch to the air source, such that when the visor is in the fully extended position the switch is operative to turn on the air source to provide a flow of air down over the wearer's face inside the visor and when the visor is in a partially or fully retracted position the switch is operative to turn off the air supply.

[0005] WO2014066983A1 discloses about an invention that includes a helmet for mining. The helmet includes: a breastplate; a shell integrated with the breastplate; and a transparent face shield that abuts the breastplate and shell. The shell surrounds a portion of a wearer's head and comprises forward directed light emitting elements, whereas the transparent face shield surrounds the remaining portion of the wearer's head. Also disclosed is a personal protection system that includes the helmet and ear protection for limiting the amount of ambient noise that the wearer hears.

[0006] Traditionally, various safety wear devices have been designed for mine workers. However, these devices fall short in offering breathing assistance, particularly in delivering oxygen when irregular breathing patterns are identified. Additionally, these devices do not effectively monitor crucial environmental factors such as air quality, temperature, and noise levels, nor do these provide the capability to adjust the wearable equipment to ensure the user’s safety under varying conditions.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to integrate a breathing support means that delivers oxygen when abnormal patterns are detected, thereby ensuring the user remains safe and well-oxygenated in hazardous conditions. In addition, the developed device also needs to monitor environmental factors such as air quality, temperature, and noise levels, and adjust the wearable device accordingly for the user’s safety.

[0021] The present invention relates to a wearable safety assistive device for mine workers that enable workers in hazardous environments to wear a solution that guarantees both their safety and comfort. In addition, the proposed device also provides oxygen when abnormal patterns are detected, for ensuring the user remains safe and well-oxygenated in hazardous conditions.

[0022] Referring to Figure 1 and 2, an isometric view of a wearable safety assistive device for mine workers and an internal view of the proposed device are illustrated, respectively, comprising a hemispherical shaped wearable frame 101 configured to fit comfortably on a user’s head, an artificial intelligence-based imaging unit 102 is arranged on the frame 101, a holographic projection unit 103 installed on the frame 101, a speaker 104 installed on the frame 101, plurality of cushioned members 201 are arranged within inner periphery of the frame 101, plurality of chambers 202 configured in between the members 201.

[0023] Figure 1 and 2 further illustrates a hollow pouch 203 configured with each of the chamber 202, a mask 105 is arranged on lateral sides of the frame 101, a motorized roller 106 coiled with a strap 107 associated with the mask 105, an oxygen supply module 108 arranged on the mask 105, multiple L-shaped extendable links 109, attached on each side of the frame 101, an augmented Reality (AR) based wearable unit 110 mounted on ends of the links 109, a belt 111 configured with a latch 112 is mounted on underside of the frame 101, the oxygen module 108 is integrated with a motorized L-shaped telescopic rod 113, a microphone 114 integrated on the frame 101.

[0024] The device disclosed herein comprising a hemispherical-shaped wearable frame 101 designed to comfortably conform to the contours of a user's head. The frame 101 is further equipped with a belt 111, which is affixed to the underside of the frame 101, and is configured with a latch 112 mechanism. This latch 112 mechanism is specifically designed to engage with a corresponding latching arrangement, thereby facilitating secure attachment and ensuring a snug, stable, and adjustable fit around the user's head. The structural configuration of the frame 101 and the belt 111- latch 112 arrangement collectively function to provide both comfort and security during wear, optimizing user experience and stability.

[0025] An artificial intelligence-based imaging unit 102 is mounted on the aforementioned frame 101 and is operatively coupled with a capacitive proximity sensor. The imaging unit 102 is configured to detect and analyze the user’s head position within a predefined proximity range. The capacitive proximity sensor is designed to detect the presence of the user’s head within this specific distance threshold, thereby facilitating the accurate and efficient activation or adjustment of the imaging unit 102 based on the user’s proximity.

[0026] The imaging unit 102 disclosed herein comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings 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 the processor which processes the captured images.

[0027] This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data which are processed by the microcontroller to detect presence of the user’s head within a predefined distance.

[0028] The capacitive proximity sensor works by emitting an electrostatic field from its sensor electrode. When the user’s body, enters this field, the body alters the capacitance between the sensor and the user’s body. The sensor detects this change in capacitance and processes the signal to determine the proximity of the user’s body. As the user’s body moves closer, the capacitance variation increases, allowing the sensor to accurately measure the distance or detect the presence of the user’s body. This change in capacitance is then converted into an output signal that triggers a microcontroller, for detecting presence of the user’s head within a predefined distance.

[0029] The capacitive proximity sensor, upon detecting the user's head within the predefined range, generates a corresponding signal that is relayed to the microcontroller. The microcontroller processes this input and, based on pre-programmed protocols, actuates a holographic projection unit 103 integrated into the frame 101. The holographic projection unit 103 then projects visual images or instructions onto the user's field of view, providing real-time guidance to ensure proper alignment and positioning of the helmet. This facilitates the correct and secure wearing of the helmet by visually assisting the user in adjusting the device to an optimal fit.

[0030] The holographic projection unit 103 operates by utilizing light modulation techniques, such as laser or LED light sources, which are directed through specialized optics to create three-dimensional visual images in mid-air. The microcontroller controls the intensity, position, and timing of light emissions based on input signals. When activated, the unit generates a holographic display that is projected onto the user’s field of view. These projected images, typically in the form of visual guides or instructions, are rendered in real-time, offering a dynamic and interactive way to communicate information regarding the correct positioning or alignment of the helmet.

[0031] An angle sensor is embedded within the frame 101 of the wearable device and is specifically designed to monitor and measure any deviation in inclination between the frame 101 and the user's head. The sensor continuously detects the angular position of the frame 101 relative to the user’s head, thereby identifying any tilting or misalignment of the frame 101 from a predefined reference position. Upon detecting such deviation, the angle sensor generates a corresponding signal, which is used to trigger corrective actions or alerts, ensuring that the frame 101 remains properly aligned with the user’s head for optimal comfort, safety, and performance.

[0032] The angle sensor operates by detecting changes in orientation through an accelerometer. As the frame 101 tilts relative to the user’s head, the sensor measures the angular deviation by analysing the shift in gravitational forces or rotational movement. The sensor then converts these measurements into electrical signals that represent the degree of inclination or tilt. These signals are processed and compared to a predefined reference, allowing the sensor to detect any misalignment. If a deviation exceeds a set threshold, the sensor activates an output to signal or trigger corrective actions.

[0033] The angle sensor, upon detecting any deviation in the inclination or tilt of the frame 101 relative to the user's head, generates a signal that is transmitted to the inbuilt microcontroller. The microcontroller processes this input and, upon determining that the deviation exceeds a predetermined threshold, actuates a speaker 104 integrated into the frame 101, to notify the user of the misalignment. This corrective alert prompts the user to adjust or reposition the frame 101, thereby ensuring proper alignment and fit for optimal comfort, stability, and safety.

[0034] The speaker 104 operates by receiving an electrical signal from the microcontroller, which encodes the audio output. The signal is then converted into sound waves through a diaphragm that vibrates in response to the electrical current. The microcontroller controls the frequency, duration, and amplitude of the signal, which determines the tone, volume, and timing of the sound emitted by the speaker 104. When activated, the speaker 104 produces an audible correctional alert, such as a warning tone or instruction, notifying the user of the frame 101 misalignment. The sound waves generated by the speaker 104 are projected into the user’s environment, delivering the alert.

[0035] Plurality of cushioned members 201 (preferably 2 to 6 in numbers) is strategically arranged along the inner periphery of the frame 101, each containing a non-Newtonian fluid. The non-Newtonian fluid is specifically selected to exhibit a variable viscosity that adjusts in response to external force or impact. Upon the occurrence of an impact, such as from a falling object, the fluid within the cushioned members 201 undergoes a rapid increase in viscosity, hardening to absorb and dissipate the energy from the impact. This enhances the protective capabilities of the frame 101 by providing additional cushioning and reducing the risk of injury to the user, thereby ensuring greater safety during such incidents.

[0036] A pressure sensor is embedded within the frame 101, specifically designed to detect any impact resulting from a falling object. The pressure sensor operates by detecting changes in force applied to its surface. When an impact from a falling object occurs, the sensor's sensing element, such as a piezoelectric or capacitive material, deforms in response to the applied pressure. This deformation generates a change in electrical capacitance or voltage, which is then converted into an electrical signal. The sensor transmits this signal to the microcontroller, which compares it against a predefined threshold.

[0037] If the pressure exceeds this threshold, indicating a significant impact, the microcontroller reactivates the speaker 104 integrated into the frame 101. The speaker 104 then emits warning signals, such as an audible alarm or alert, to notify the user to move away from the danger zone, thereby facilitating prompt action to mitigate potential harm.

[0038] Plurality of chambers 202 is strategically configured between the cushioned members 201 within the frame 101, each chamber 202 being designed to store a cooling gel. The cooling gel is selected for its thermally conductive properties, allowing it to absorb and dissipate heat when in contact with the user’s head. These chambers 202 are sealed to prevent leakage of the gel, ensuring consistent and effective cooling. The arrangement of the chambers 202 facilitates the even distribution of the gel across the frame 101 interior, providing thermal regulation and enhancing user comfort by reducing heat buildup during extended wear, thereby promoting a more comfortable and safe user experience.

[0039] A moisture sensor is embedded within the cushioned members 201 of the frame 101, designed to detect the presence of excess moisture on the user’s head. Upon detecting a predefined level of moisture, the sensor transmits a signal to the microcontroller. In response, the microcontroller activates a motorized iris aperture integrated with each chamber 202, causing it to open. This action allows the cooling gel stored within the chamber 202 to be dispensed into a hollow pouch 203 configured within each chamber 202. The cooling gel is then applied to the user’s head, alleviating excess moisture and providing a cooling effect, thereby enhancing comfort during wear.

[0040] The moisture sensor detects excess moisture by measuring changes in electrical resistance or capacitance on its surface. When moisture comes into contact with the sensor, the electrical properties of the sensor change due to the conductive nature of water. This variation is converted into an electrical signal, which is then transmitted to the microcontroller. The microcontroller processes the signal and, detecting excess moisture on the user’s head.

[0041] A sensing module is integrated within the frame 101, comprising both a dust sensor and a gas sensor, each designed to detect environmental hazards around the user. The dust sensor operates by using a light scattering or laser-based method to detect airborne particles. As particles pass through the sensing area, these scatter the emitted light, and the sensor measures the intensity of this scattered light. The amount of scattered light correlates with the concentration of dust particles in the air. The sensor converts this data into an electrical signal, which is sent to the microcontroller. The microcontroller analyses the data and detecting unfavorable air in surrounding environment of the user.

[0042] The gas sensor functions by utilizing a chemical sensing element, such as a semiconductor or electrochemical cell, which reacts with specific gases in the environment. When harmful gases are present, they interact with the sensor's surface, causing a change in electrical properties, such as resistance or voltage. This change is detected by the sensor and converted into an electrical signal. The signal is then transmitted to the microcontroller, which analyzes the concentration of the detected gases and detects unfavorable air in surrounding environment of the user.

[0043] Based on the signals received from the dust sensor and the gas sensor, the microcontroller regulates the deployment of a mask 105, which is positioned on the lateral sides of the frame 101. The mask 105 is mounted on a motorized ball-and-socket joint, allowing for precise and controlled movement. Upon detecting harmful levels of dust or gases, the microcontroller activates the motor, causing the ball-and-socket joint to maneuver the mask 105 into position.

[0044] The mask 105 is then deployed over the user’s nose and mouth, providing immediate protection by filtering out harmful particles or gases in the surrounding environment, ensuring user safety. The motorized ball and socket joint mentioned here consists of a ball-shaped element that fits into a socket, which provides rotational freedom in various directions. The ball is connected to a motor, typically a servo motor which provides the controlled movement. The mask 105 is attached to the socket of the motorized ball and socket joint, the microcontroller sends precise instructions to the motor of the motorized ball and socket joint. The motor responds by adjusting the ball and socket joint and rotates the ball in the desired direction, and this motion is transferred to the socket that holds the mask 105. As the ball and socket joint move, it provides the necessary movement to the mask 105 for deploying the mask 105 over nose and mouth of the user.

[0045] The mask 105 is also deployed manually via speech commands via a microphone 114. The microphone 114 mentioned herein works as a transducer that converts sound waves into audio signal. The microphone 114 on receiving the input commands from the user converts the input signal into electrical signal and sends it to the microcontroller. The microcontroller processes the received signals in order to analyze the voice inputs of the user and upon analyzing the voice commands the microcontroller actuates the device and accordingly commands the device to carry out deployment of the mask 105.

[0046] A motorized roller 106, coiled with a strap 107 and integrated with the mask 105, is positioned to facilitate the wrapping of the mask 105 securely around the user’s nose and mouth. Upon activation by the microcontroller, the motorized roller 106 unwinds the strap 107, drawing the mask 105 tightly across the user’s face. The strap 107 tension ensures a secure fit, effectively shielding the user from inhaling harmful dust, gases, or other airborne contaminants. This deployment arrangement is designed to promote safe and efficient breathing by maintaining a proper seal and preventing exposure to detrimental air, thereby ensuring the user's respiratory safety in hazardous environments.

[0047] A breath sensor is embedded within the mask 105, designed to detect and monitor the user's breathing patterns in real time. The sensor operates by measuring airflow, pressure, or respiratory rate, typically through methods such as piezoelectric, capacitive, or infrared technology. The breath sensor continuously monitors the user's inhalation and exhalation cycles, generating corresponding signals that are transmitted to the microcontroller. The microcontroller processes this data to assess the user's respiratory status, potentially triggering alerts or adjusting the mask 105 functionality (e.g., ventilation or filtration) based on detected patterns, ensuring optimal respiratory support and maintaining comfort during use.

[0048] Upon detecting abnormal breathing patterns or a significant change in airflow, indicative of discomfort or respiratory distress, the microcontroller actuates the oxygen supply module 108 integrated within the mask 105. The oxygen module 108 consists of a collapsible pipe and a motorized L-shaped telescopic rod 113. Upon detection of irregular breathing, the motorized rod 113 extends, positioning the collapsible pipe in proximity to the user’s airway. The oxygen is delivered to the user through an iris hole in the mask 105. The telescopic rod 113 are capable of adjusting the angle and position of the pipe in response to the user's breathing patterns, ensuring precise alignment for optimal oxygen delivery and respiratory support.

[0049] The rod 113 is pneumatically actuated, wherein the pneumatic arrangement of the rod 113 comprises of a cylinder incorporated with an air piston and the air compressor, wherein the compressor controls discharging of compressed air into the cylinder via air valves which further leads to the extension/retraction of the piston. The piston is attached to the telescopic rod 113, wherein the extension/retraction of the piston corresponds to the extension/retraction of the rod 113. The actuated compressor allows extension of the rod 113 to provide oxygen to the user by adjusting angle and position of the pipe.

[0050] A GPS (Global Positioning System) module is integrated with the microcontroller to continuously track the user's location. This location data is transmitted wirelessly to a concerned authority via a computing unit, which is linked to the microcontroller. The concerned authority accesses the user’s real-time location and monitor their movements. In the event that the authority identifies potential obstacles or determines that the user is situated in hazardous areas, such as unfavourable sections of caves or other dangerous environments, the microcontroller trigger alerts or provide corrective actions, such as notifying the user to move to a safer area, thereby ensuring their safety.

[0051] Upon receiving location data and hazard-related information from the concerned authority, the microcontroller activates plurality of L-shaped extendable links 109, each attached to the sides of the frame 101 and works in the similar manner as of rods. These links 109 extend outwardly, and at their ends, an Augmented Reality (AR) based wearable unit 110 is mounted. The AR unit, upon activation, projects real-time visual guidance or instructions, enabling the user to receive direct, actionable directions from the concerned authority. This real-time AR guidance assists the user in navigating away from hazardous areas, such as unfavourable sections of caves, facilitating a safe and efficient escape route by overlaying critical information in the user’s field of view.

[0052] The GPS module is linked with a database containing information on predefined danger zones, such as hazardous areas or regions with potential risks. When the user enters one of these danger zones, the GPS module detects the location and cross-references it with the database. Upon confirming the user's presence in a hazardous area, the microcontroller triggers alerts through the AR wearable unit 110 or the speaker 104. The AR unit provides real-time visual guidance, displaying safe routes or escape paths, while the speaker 104 emits audible warning signals or instructions. These notifications assist the user in navigating to a safer area, ensuring timely and effective escape from danger.

[0053] The frame 101 is installed with a temperature sensor which determines temperature around the user. The temperature sensor comprises crucial components such as an infrared sensor, an optical arrangement, and a detector. It functions on the principle of detecting infrared radiation emitted by the surrounding. When the temperature exceeds absolute zero, it emits infrared radiation. The sensor captures this radiation using its optical arrangement, directing it onto a detector. Common detectors, like thermopiles or pyroelectric sensors, then convert the received infrared energy into an electrical signal. This signal undergoes processing by electronic components, translating it into a temperature reading around the user.

[0054] In the event that the temperature detected by the temperature sensor exceeds a predefined threshold, the microcontroller generates a wireless notification to the computing unit linked to the concerned authority. This notification includes the user's current location data, enabling the authority to review the user's position in real time. If the user remains within a high-temperature zone, the concerned authority can take immediate action, such as sending a warning to the user or initiating emergency protocols. This device ensures the protection of the user by alerting the concerned authority during mining operations, minimizing the risk of heat-related injuries or hazards.

[0055] A noise-cancellation mechanism 301 is incorporated into the frame 101, comprising a C-shaped pipe 302 integrated with electromagnetic springs 303 and air cushion padding 304. The arrangement is actuated by the microcontroller, which responds to input from an acoustic sensor embedded in the frame 101. When ambient noise exceeds a predefined threshold, as detected by the acoustic sensor, the microcontroller triggers the electromagnetic springs 303 to extend and tilt (as shown in figure 3).

[0056] This motion positions the air cushion padding 304 around the user's ears, applying pressure to block out harmful environmental noise. The arrangement thereby enhances the user’s ability to concentrate on desired tasks by providing effective noise isolation in high-noise environments. The electromagnetic springs 303 operates by utilizing a coil and a magnetic field. When an electrical current is applied to the coil, it generates a magnetic field that interacts with a permanent magnet or ferromagnetic material within the springs 303. This interaction causes the springs 303 to extend or retract in response to the strength of the magnetic field, allowing precise control of its movement. The microcontroller regulates the current, thereby controlling the positioning of the springs 303. Upon activation, the springs 303 movement extends the air cushion padding 304 to the user’s ears, applying the necessary pressure to block unwanted environmental noise.

[0057] The acoustic sensor detects ambient noise levels by capturing sound waves through a microphone 114 or piezoelectric element. The sensor converts the sound vibrations into electrical signals, which are then processed to measure sound intensity and frequency. If the detected noise level exceeds a predefined threshold, the sensor triggers a signal to the microcontroller. The microcontroller then processes this data and, based on the threshold, activates the noise-cancellation mechanism 301. The sensor continuously monitors the surrounding environment, ensuring that the noise-cancellation arrangement remains responsive and adjusts in real-time to effectively block harmful noise when needed.

[0058] Moreover, a battery is associated with the device for powering up electrical and electronically operated components associated with the device and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the device, derives the required power from the battery for proper functioning of the device.

[0059] 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. Various modifications of the disclosed embodiments, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. , Claims:1) A wearable safety assistive device for mine workers, comprising:
