Description:FIELD OF THE INVENTION

[0001] The present invention relates to a natural hazard detection and alert device that is accessed by a user for detecting potential natural hazards in real-time to ensure timely alerts and necessary precautions, thereby preventing casualties and minimizing damage caused due to such hazards.

BACKGROUND OF THE INVENTION

[0002] Natural disasters such as earthquakes, landslides, wildfires, and floods pose a significant threat to human lives and infrastructure. Detecting these hazards in advance and providing real-time alerts is crucial for minimizing damage and ensuring the safety of individuals in affected areas. In such cases, conventional detection methods rely on static sensors or manual observations, which may not always provide accurate or timely warnings. Furthermore, there are challenges in effectively guiding people to safety, especially in areas with limited communication infrastructure.

[0003] Sometimes, depending on the nature of the disaster and the affected location, there are chances of delayed hazard detection and warning dissemination. Typically, early warning systems are deployed to alert people regarding impending disasters; however, due to geographical constraints, sensor limitations, and response delays, warnings might not reach all affected individuals on time. Additionally, in cases of sudden disasters such as landslides or earthquakes, there is no real-time guidance system to help people evacuate safely. As a result, many individuals find themselves trapped or unable to reach safe zones efficiently.

[0004] However, delayed detection and inadequate guidance systems become a major obstacle in ensuring effective disaster response, leading to increased casualties and property damage. Additionally, conventional detection mechanisms do not provide real-time hazard mapping, making it difficult for authorities to assess the severity of the situation and deploy rescue operations accordingly. In such scenarios, individuals are often left without proper assistance, increasing the risk of injury or loss of life.

[0005] US6169476B1 discloses an early warning system for all natural and manmade disasters to collect and analyze data in real time as disasters occur, and when necessary, transmit early warnings to cause mitigation responses to lessen the disaster impact on lives and property. The system detects disasters in real time and determines the type, magnitude, speed, direction, and the expected geographic area to be impacted. Early warnings are transmitted to a wide variety of microprocessor receiver/controllers embedded in commonly used consumer and commercial devices to create a universal standard for receiving warnings and allow both human and automated responses during disasters to greatly increase the effectiveness of the warnings to users. The system determines precise real time position and location coordinates as well as other types of current geographic information data for all mobile and stationary devices capable of receiving early warning signals. This allows the system to transmit directed early warnings to only those specific receivers or group of receivers that are in danger from a disaster as determined by the current location and geographic information for each receiver. The system minimizes false or unnecessary warnings and greatly increases a receiver's confidence in the necessity to take effective mitigation actions during natural or manmade disasters. The system also provides emergency response instructions in a timelier manner to emergency response personnel in all areas prior to a disaster Impact to allow a higher quality emergency mitigation response.

[0006] US20070296575A1 discloses a disaster alert system and disaster alert devices for use in the system. Each disaster alert device includes a radio receiver, and a processor programmed to monitor radio transmissions from one or more central stations for disaster alerts directed to the location of the disaster alert device. Each alert device also includes an audio unit to alert personnel located at the site of the device to the precise nature of the disaster. The disaster alert devices are pre-programmed with information identifying the precise use location of the warning device. This use location information includes latitude and longitude of the use location and may also include other location information such as street address and zip code. Warnings are broadcast from central stations identifying with latitude and longitude information specific at-risk regions to which the warnings are directed which could be, for example, nationwide, state-wide, countywide, or too much smaller regions, such as several houses on a single street or even a single residence. Each disaster alert device is preferably programmed to ignore all warnings directed to at-risk regions that do not include the latitude and longitude of the use location of the device.

[0007] As per the discussion in the above-mentioned prior arts, several methods and systems are available for monitoring environmental changes and detecting hazards. However, these conventional systems are often limited in their mobility, coverage, and response efficiency and do not actively assist individuals in navigating to safer locations or provide real-time hazard assessment. Additionally, these systems lack to enable a coordinated response in disaster-prone areas.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that not only detects impending natural disasters but also provides real-time guidance to individuals for reaching safe locations. In addition, the developed device must be capable of communicating with emergency response teams, and assisting in rescue operations to minimize casualties and property damage effectively.

DETAILED DESCRIPTION OF THE INVENTION

[0023] 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.

[0024] 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.

[0025] 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.

[0026] The present invention relates to a natural hazard detection and alert device that is configured to continuously monitor environmental parameters to determine the presence of impending natural hazards and subsequently notify concerned authorities regarding the detected hazard for initiating necessary precautionary and rescue measures.

[0027] Referring to Figure 1, an isometric view of a natural hazard detection and alert device is illustrated, comprising a housing 101 having a plurality of motorised omnidirectional wheels 102, a thermal camera 103 mounted on the housing 101, plurality of acoustic sensors 104 are arranged over the housing 101, a projection unit 105 installed on the housing 101, a telescopic rod 106 is installed on the housing 101, having an umbrella mechanism 107 at an upper end of the rod 106, a protective mesh 110 is attached with umbrella mechanism 107, a conductive telescopic stick 108 having a pointed bottom end and a conductive circular mesh 109 frame attached at an upper end of the stick 108, a plurality of robotic arms 111 are coupled with the housing 101, a motorised roller 112 is installed with the housing 101, carrying a spool of rope 113, a chamber 114 is provided within the housing 101, a nozzle 115 mounted on the housing 101, a pair of scissor mechanism 116 attached with lateral surfaces of the housing 101, each the scissor mechanism 116 having an electromagnet 117, a plurality of L-shaped telescopic links 118 is mounted with lateral surfaces of the housing 101, each having a suction cup 119 at an end.

[0028] The device disclosed herein comprises a housing 101 equipped with a set of motorized omnidirectional wheels 102 that allow it to traverse different types of terrain. These wheels 102 are integrated with suspension mechanisms, ensuring that the housing 101 moves smoothly over uneven and rugged surfaces without losing stability. The motorized omnidirectional wheels 102 provide movement across various types of terrain, including uneven, rocky, and unstable surfaces. Each wheel 102 is powered by an independent motor, allowing precise control over speed, direction, and maneuverability. The omnidirectional wheels 102 consist of a series of smaller rollers mounted around the circumference of the main wheel. These rollers are positioned at an angle to the wheel’s rotation axis, enabling the housing 101 to move in multiple directions without requiring physical rotation of the housing 101, which allows smooth lateral movements, diagonal shifts, and on-the-spot rotation, making the device highly adaptable for disaster-prone or obstructed environments.

[0029] To enhance stability and ensure continuous ground contact, each wheel 102 is integrated with the suspension. The suspension absorbs shocks and vibrations, preventing abrupt jolts that could disrupt the device’s operations. In an embodiment of the present invention, the suspension is likely designed using spring-loaded dampers, hydraulic actuators, or elastomer-based shock absorbers, which help in adapting to the surface contour by adjusting the wheel 102 height dynamically. This allows the wheels 102 to compress or extend based on the terrain conditions, ensuring that the housing 101 remains level and steady, even when moving over debris, rocks, or steep inclines.

[0030] Meanwhile, multiple LIDAR sensors (not shown) are embedded in the housing 101, which is responsible for creating a detailed 3D map of the surrounding terrain, enabling precise navigation and hazard detection. The LiDAR sensor sends out rapid laser pulses in a sweeping motion. These pulses travel through the air and interact with the surrounding terrain. When the laser pulses encounter the surrounding terrain, the laser bounces off from the surface of the terrain. The LiDAR sensor precisely measures the time it takes for these laser pulses to travel to the surface of the surrounding terrain and back to the sensor. This measurement is known as time-of-flight and as the LiDAR sensor continues to emit laser pulses and measure their time-of-flight, it creates a dense point cloud of data points. Each data point corresponds to a specific location on the surrounding terrain’s surface. By combining the time-of-flight data from multiple laser beams at various angles, the LiDAR builds a detailed 3D (three-dimensional) map or point-of-cloud of the surrounding terrain.

[0031] Additionally, a thermal camera 103 is mounted on the housing 101 to continuously monitor temperature variations in both the terrain and the ambient environment. The thermal camera 103 operates based on infrared (IR) thermal imaging principle, which detects the heat emitted by surroundings. Every object, regardless of its temperature, emits some level of infrared radiation; the intensity of this radiation increases as the temperature of the object rises. The thermal camera 103 captures this infrared radiation and converts it into a thermal image, allowing the device to visualize temperature differences across its environment.

[0032] Internally, the thermal camera 103 consists of an infrared sensor array, which is typically made up of micro bolometers, a small heat-sensitive detector that measure the infrared radiation intensity at different points. These micro bolometers do not require an active light source; instead, they passively detect the infrared energy naturally emitted by surrounding environments. When infrared radiation reaches the sensor, it causes a change in electrical resistance, which is then converted into a digital temperature value. The camera 103 processes this data to generate a heat map of the surroundings, where different colours or intensity levels represent varying temperatures.

[0033] The thermal camera 103 scans and analyses the temperature of the terrain and the ambient environment, which helps in detecting potential natural hazards such as wildfires, volcanic activity, or underground heat anomalies that may indicate an impending disaster. For example, if a sudden spike in ground temperature is detected, it might indicate an earthquake-prone zone, underground fire, or heat stress in structural materials. Additionally, in colder environments, the thermal camera 103 identifies frost-prone areas, icy surfaces, or dangerously low temperatures that might affect mobility.

[0034] Concurrently, a series of acoustic sensors 104 are also arranged on the housing 101, captures and analyses environmental sounds, which helps in detecting potential hazards such as earthquakes, landslides, or other disturbances. The acoustic sensors 104 are designed to recognize specific acoustic signatures associated with environmental sounds. In an embodiment of the present invention, the acoustic sensors 104 consists of a microphone or an array of microphones to pick up the sounds caused by environmental sounds. The captured audio signals are then processed using artificial intelligence modules to distinguish background noise and insect generated sounds.

[0035] A detection module is linked with a microcontroller provided in the housing 101, which processes real-time data collected from the plurality of LIDAR sensors, the thermal camera 103, and the plurality of acoustic sensors 104. The detection module determines an impending natural hazard based on the analysed data.

[0036] Upon detection, a communication unit linked with the microcontroller is activated to notify remotely located computing units regarding the natural hazards identified by the detection module. The microcontroller is further configured with a swarm module, which enables transfer of information between communication units of multiple such devices. The swarm capability allows the plurality of devices to act collectively for enhanced natural hazard detection and transmission of alerts.

[0037] The swarm module mimics the behaviour of biological swarms, such as those observed in ants, bees, or flocks of birds, where individual units work collectively to respond to environmental changes efficiently. Internally, the swarm module operates through a decentralized communication protocol, meaning each device is able to function autonomously while still being aware of the actions and data from surrounding units. The microcontroller within each device runs a distributed protocol that enables devices to exchange information wirelessly via a communication unit, which is based on Wi-Fi, Bluetooth, LoRa, or mesh networking technologies, which allows the devices to form an ad-hoc network, where they continuously update each other on detected hazards, positional changes, and environmental conditions.

[0038] Once a natural hazard is detected by the detection module of a particular device, the swarm module ensures that this information is immediately transmitted to nearby devices. For example, if multiple devices detect the same hazard, they aggregate and refine the data before relaying it to a remotely located computing unit via the communication unit, which reduces false alarms and enhances situational awareness across the network.

[0039] Moreover, the swarm module enables coordinated movement and task execution among the devices. For example, if the devices detect a hazardous area such as unstable terrain or an impending flood, they self-organizes into a barrier formation using their scissor mechanism 116 and telescopic links 118 to restrict access. In continuation, the pair of scissor mechanism 116 attached to lateral surfaces of the housing 101 and equipped with an electromagnet 117 at an end, which allows for the interconnection of a plurality of devices. This interconnection facilitates the formation of a barrier to prevent users from traveling toward precarious areas.

[0040] The scissor mechanism 116 consists of two arms that cross over each other in a crisscross or X-shaped pattern. These arms are typically made of sturdy materials like steel or aluminum, ensuring strength and stability. At the intersection of the arms, there are pivot joints that allow the arms to rotate relative to each other. The primary function of the scissor mechanism 116 is to transform motion or force applied at one end into linear motion at the other end typically in the horizontal direction. When a force is applied to push the arms apart at one end, the scissor arms begin to unfold. This action causes the attached electromagnets 117 to get extend for interconnection of multiple housings 101 to form the barrier.

[0041] The electromagnet 117 consist 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 117 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 electromagnet 117 activates and interconnect with multiple housing 101 to form the barrier. Simultaneously, the wheels 102 are actuated by the microcontroller as per the swarm module, allowing the interconnected housing 101 to translate and arrange themselves to form the barrier efficiently.

[0042] Concurrently, the L-shaped telescopic links 118 are equipped with a suction cup 119 at an end to stabilize the housing 101 over the ground surface when the devices are arranged as a barrier to ensure a strong and stable barricade, restricting access to hazardous zones. The suction cup 119 is used to create a vacuum seal between the surface and the housing 101. When the suction cup 119 is pressed against the surface, the initial contact creates a seal between the cups and the surface, this seals off the area within the suction cup 119. The suction cup 119 is designed to maintain a relatively airtight seal.

[0043] Additionally, if a group of devices detects a trapped individual or vehicle, they work collectively by deploying their robotic arms 111 and motorized rollers with rope 113 to assist in rescue operations. The robotic arms 111 are coupled with the housing 101 to perform lifting of items and debris, which is crucial in safeguarding users during natural hazards, as determined by the detection module. The robotic arms 111 are used to clear pathways, remove obstacles, and assist in rescue operations by retrieving trapped individuals or providing support in unstable environments.

[0044] Herein, the motorized roller 112 is installed with the housing 101, which carries a spool of rope 113. The roller 112 is designed to pull users and vehicles out of precarious situations, as detected by the detection module. The motorized roller 112 provides controlled deployment and retraction of the rope 113, ensuring that individuals or vehicles trapped in floods, landslides, or other hazardous conditions can be safely extricated.

[0045] Additionally, a telescopic rod 106 is installed on the housing 101, featuring an umbrella mechanism 107 at its upper end. This umbrella mechanism 107 is fitted with a protective mesh 110, which is designed to catch falling debris as detected by the detection module, ensuring safety in hazardous conditions. Upon detection, a signal is sent to the microcontroller, a pneumatic unit to extend the telescopic rod 106 rapidly. The rod 106 extends to a height sufficient to provide overhead coverage, ensuring a wide protection radius beneath it.

[0046] The umbrella mechanism 107 operates using a central hub and multiple articulated arms that radiate outward, similar to the ribs of a conventional umbrella. These arms are spring-loaded or controlled by small motors, allowing them to open or close on command. When the telescopic rod 106 reaches full extension, the umbrella mechanism 107 is triggered to expand.

[0047] This movement unfolds the protective mesh 110, creating a wide canopy-like barrier positioned above the housing 101. The protective mesh 110 is made of metallic wire mesh, capable of absorbing and dispersing the impact energy of falling objects. The mesh is anchored to the umbrella ribs, ensuring structural integrity when deployed. Once deployed, the umbrella mechanism 107 remains open as long as the hazard persists. After the risk of falling debris subsides, the microcontroller sends a retraction command, causing the umbrella mechanism 107 to collapse back into a compact form, and the telescopic rod 106 to retract into the housing 101 for storage, which ensures that the mechanism is only deployed when necessary, minimizing space usage and energy consumption.

[0048] Additionally, a lightning arrestor is attached to the housing 101, which consists of a conductive telescopic stick 108 having a pointed bottom end and a conductive circular mesh 109 frame at its upper end to receive lightning and redirect it into the ground via the telescopic stick 108, ensuring the safety of the device and nearby users.

[0049] The housing 101 is having an electrostatic charge sensor, which is capable of detecting impending lightning. Lightning is preceded by the accumulation of electrostatic charges in the atmosphere, caused by the interaction of positive and negative charges between storm clouds and the ground. The electrostatic charge sensor detects these charge variations by measuring the strength and polarity of the local electric field. It operates based on the principle of electrostatic induction, wherein a conductive sensing element within the sensor responds to nearby electrical charges without direct contact.

[0050] In another embodiment of the present invention, internally, the sensor consists of a conductive plate or antenna, which collects ambient electrostatic charge data. This charge induces a small voltage or current, which is then amplified and processed by an analog-to-digital converter (ADC) within the sensor circuitry. The microcontroller analyses this data in real-time, comparing the detected charge intensity and rate of change against predefined thresholds. Rapid fluctuations in electrostatic charge indicate an increasing likelihood of a lightning strike, prompting the device to initiate protective actions.

[0051] The microcontroller (not shown) deploys the telescopic stick 108, extending it into the air. The conductive circular mesh 109 frames at the top of the stick serves as a lightning collection point, attracting the lightning discharge. The pointed bottom end of the stick is driven into the ground to safely dissipate the lightning energy into the earth, preventing damage to surrounding objects or individuals.

[0052] Upon detecting an increased electrostatic charge, the microcontroller actuates the stick and extend it, thereby raising the circular mesh 109 frame. The extension of the stick is powered by a pneumatic unit that utilizes the compressed air to extend or retract the stick 108. Simultaneously, the bottom end of the telescopic stick 108 is buried into the ground surface to provide an effective grounding path.

[0053] A projection unit 105 is installed on the housing 101, which serves the purpose of projecting visual warnings regarding the detected natural hazard. The projection unit 105 displays visual guidance to users in the vicinity, enabling them to travel to safe locations. The projection unit 105 ensures that clear and visible warnings are available even in low-visibility conditions, helping individuals navigate away from danger. In an embodiment of the present invention, the projection unit 105 is typically a laser based projection unit 105 that serves as a visual guide for the user, making it simple for the user to take correct precautions or actions for the same.

[0054] The microcontroller sends a signal to the laser projection unit 105 to highlight the desired position in the proximity of the user. The laser projection unit 105 consists of a laser source, typically a diode laser that emits a focused beam of coherent light. Within the laser projection unit 105, various optical components are used such as lenses, mirrors, and prisms to shape and direct the laser beam. The laser projection unit 105 is capable of projecting lines, dots, or any other pattern in order to warn the user regarding the detected natural hazard.

[0055] Furthermore, a chamber 114 is provided within the housing 101 for the storage of friction material. The chamber 114 is designed to dispense the friction material onto an icy surface through a nozzle 115 mounted on the housing 101 to enhance the stability of the device by improving traction over the icy surface. The nozzle 115 serves as the exit point for the friction material to ensure even distribution of the material over the icy surface. As the housing 101 moves over icy terrain, the nozzle 115 operates in real time, ensuring that the friction material is only dispensed when necessary, thereby reducing the risk of slipping or losing control when operating in cold and icy environments.

[0056] The present invention works best in the following manner, where the housing 101 begins its operation by navigating its surroundings using motorized omnidirectional wheels 102 integrated with a suspension system, which allows it to move smoothly over rugged, uneven, or hazardous terrain. Simultaneously, LIDAR sensors continuously scan the environment, generating a detailed 3D terrain map. This mapping data helps the device understand its surroundings, avoid obstacles, and detect changes in terrain that indicates potential hazards, such as landslides or unstable ground. To identify potential threats, the thermal camera 103 which detects temperature fluctuations, allowing it to identify wildfires, extreme cold, or abnormal heat sources. The acoustic sensors 104 register ambient sound variations, helping detect earthquakes, landslides, or structural collapses based on distinct sound patterns. Additionally, the electrostatic charge sensor monitors atmospheric electrical activity, detecting impending lightning strikes before they occur. Once the detection module processes the sensor data and identifies a natural hazard, it triggers the microcontroller to take immediate action. The swarm module, which allows it to communicate with other similar devices, enabling coordinated responses. The swarm capability ensures that hazard information is shared across multiple units, allowing them to work together in mapping danger zones, alerting nearby users, and executing collective safety measures. Additionally, the communication unit transmits hazard alerts to remotely located computing units, ensuring that authorities or response teams receive real-time updates. If falling debris is detected, the telescopic rod 106 extends from the housing 101, deploying an umbrella mechanism 107 fitted with a protective mesh 110 to catch debris and prevent injuries. In case of an impending lightning strike, the telescopic stick 108 with a circular mesh 109 frame, grounding the lightning safely into the earth. For icy terrain, the housing 101 improves stability by dispensing friction material through a nozzle 115 mounted on its housing 101, ensuring that both the housing 101 and nearby users maintain traction on slippery surfaces. Beyond hazard detection, the device is also designed to assist individuals in distress by using the robotic arms 111 that is used to lift debris, remove obstacles, or aid trapped users during emergencies. Additionally, a motorized roller 112 with a rope 113 spool is included, allowing the device to pull individuals or vehicles out of precarious situations, such as deep snow, water, or unstable terrain. To ensure public awareness, the projection unit 105 that displays visual warnings about detected hazards and provide directional guidance, helping individuals safely navigate away from danger zones. In scenarios where hazardous zones need to be restricted, the housing 101 work with other units to form a physical barrier, which achieved through scissor mechanism 116 with electromagnet 117 that allow multiple housing 101 to interconnect, preventing people from entering dangerous areas. Additionally, L-shaped telescopic links 118 with suction cups 119 help stabilize the devices over the ground while forming the barrier. The swarm module coordinates the movement of multiple devices, ensuring that they automatically arrange themselves into an optimal formation.
