Description

SENSOR SYSTEM FOR DETECTING OBJECTS IN WORK PLATFORM SAFETY ZONECROSS REFERENCE TO RELATED PATENT APPLICATION

[0001] This application claims priority to, and the benefit of, U.S. Provisional Patent Application No. 63 / 540.228 filed September 25, 2023. the entire contents of which are hereby incorporated herein by reference for all purposes.BACKGROUND

[0002] Mobile elevating work platforms (MEWPs) and other elevated moving and / or stationary platforms are widely used in construction, maintenance, and other industries to allow workers to perform tasks at height. These platforms may typically consist of a work platform mounted on an extendable arm or scissor mechanism, allowing the platform to be raised and positioned as needed. These MEWP platforms, which include devices such as cherry pickers, scissor lifts, and boom lifts, allow workers to access elevated areas safely and efficiently. While MEWPs and other elevated moving and / or stationary platforms provide an efficient means of working at elevation, they also present potential safety' hazards, particularly related to the potential for objects to fall from the platform, which can cause injury to personnel or damage to property' below.

[0003] Traditionally, safety measures such as physical barriers, safety nets, and manual spotters have been employed to mitigate these risks. These methods, while useful, have limitations in terms of flexibility and effectiveness. Physical barriers and nets can be cumbersome and timeconsuming to set up and may not be practical in all situations. Manual spotters rely heavily on human vigilance, which can be subject to lapses due to fatigue or distraction. As workplace safety standards have become more stringent, there is an increasing need for more robust and reliable safety systems for MEWPs and other elevated moving and / or stationary' platforms.

[0004] Furthermore, the dynamic nature of many work sites where MEWPs and other elevated moving and / or stationary platforms are used complicates safety management. Work zones often change as tasks progress, and the platform may need to be moved multiple times during a single operation, necessitating constant reevaluation and adjustment of safety measures. This mobility introduces additional challenges in maintaining consistent safety zones around the platform.

[0005] Recent advancements in sensor technology have opened up new possibilities for enhancing the safety' of MEWPs. Various ty pes of sensors, including ultrasonic, infrared, and laser-based systems, have been explored for obstacle detection and collision avoidance inindustrial and automotive applications. However, adapting these technologies to the unique challenges of MEWP and other elevated moving and / or stationary platform operations presents several difficulties, including the need for comprehensive coverage around the platform, reliability in diverse environmental conditions, and / or integration with existing MEWP control systems.

[0006] The use of electronic safety systems, incorporating sensors and alarms, has been explored as a means to enhance safety around MEWPs and other elevated moving and / or stationary platforms. These systems can potentially offer more consistent and reliable monitoring of safety zones compared to traditional methods. However, existing electronic systems often focus solely on detecting collisions or proximity to fixed structures and may not adequately address the specific risks associated with objects falling from height.

[0007] Therefore, there is a general need for improvements in safety systems for MEWPs and other elevated moving and / or stationary platforms that can effectively detect and warn about objects falling from elevated work platforms, as well as the presence of personnel in danger zones, thereby enhancing overall safety at work sites. Improved systems would ideally be adaptable to various types of MEWPs and other elevated moving and / or stationary platforms and capable of functioning effectively in the diverse and dynamic environments typical of construction and maintenance work.SUMMARY[0008| This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description.

It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure. Rather, the description also encompasses combinations and modifications to those exemplary aspects described herein.

[0026] The present disclosure provides a system designed to enhance safety in work environments involving mobile elevating work platforms (MEWPs) and other elevated mobile or stationary platforms. The system incorporates a variety of sensors that are strategically positioned on the work platform, the MEWP or other elevated mobile or stationary platform itself, and other associated elements such as safety cones or pylons and utility poles.

These sensors may employ various detection technologies, such as radar, LiDAR. passive infrared sensors, proximity sensors, optical sensors, ultrasonic sensors, cameras, temperature sensors, or RFID, to monitor the safety zone.

[0028] The system may also include a computing device in communication with the sensors. This computing device is configured to receive sensor data, process it, and generate work session data based on the received sensor data. The work session data may include information about the establishment of the safety system, the number of entries into and exits from the safety zone, the identification of personnel associated with the zone, and other relevant details.

[0029] In some cases, the system may also include visual indicators, such as LEDs or lasers, to visually demarcate the safety zone on the ground. Additionally, the system may incorporate alarms that can be triggered when an object or a user is detected within the safety zone. These alarms may be audible, visual, or tactile, providing immediate alerts to potential safety hazards.

[0030] Overall, the system described herein offers a comprehensive and adaptable solution for enhancing safety around MEWPs or other elevated mobile or stationary platforms, capable of addressing the dynamic and diverse environments typical of construction and maintenance work.

[0031] Referring to FIG. 1A, an example of the system 100 is depicted. The system 100 includes a mobile elevating work platform (MEWP) 101, which may be any type of vehicle or equipment capable of raising and lowering a work platform 102. While the example of FIG. 1A may show the MEWP 101. this is for example purposes only, as the methods and system described with reference to FIGs. 1A-F are contemplated to be used with and applicable to other elevated mobile or stationary platforms, including, but not limited to, cranes, derricks, fixed platforms, scaffolding, and stationary elevated platforms. As such, the features, operations and capabilities described with reference to the MEWP 101 in FIGs. 1A-F may also be applicable to these other elevated mobile or stationary platforms. The MEWP 101 may include, for example, a construction vehicle, crane, scissor lift, jig lift, backhoe loader, tractor, crawler, bulldozer, loader, excavator, forklift, road roller, skid steer, compactor, trencher, grader, agricultural tractor, bulldozer, track skidder, military engineering vehicle, compact excavator, dragline excavator, dredge, reclaimer, steam shovel, suction excavator, trencher, yarder, feller bundler, harvester, skidder, track harvester, wheel forwarder, wheel skidder, pipe layer, fresno scraper, scraper, wheel tractorscraper, construction tractor, mining tractor, construction truck, mining truck, articulated hauler,articulated truck, water wagon, wheel dozer, soil stabilizer, loader, skip loader, wheel loader, track loader, cherry’ picker, knuckleboom loader, telescopic handler, asphalt paver, cold paner, cure rig, pneumatic tire compactor, roller, slipform paver, vibratory compactor, stomper, roadheader, tunnel boring machine, underground mining equipment, ballast tamper, drilling machine, pile driver, rotary' tiller, lowboy trailer, street sweeper, telescopic lift, scissor lift, man lift, boom lift, compactor, plow, mining equipment, boring equipment, planer, crawler carrier, crawler loader, truck, bucket truck, cab truck, chassis truck, concrete mixer truck, concrete pump truck, digger derrick truck, flat bed truck, flatbed dump truck, fuel truck, lube truck, rollback truck, military truck, logging truck, rolloff truck, sanitation truck, semi-trailer truck, semi-tractor trailer, tanker truck, tow truck, vacuum truck, knuckleboom truck, boom truck, dump truck, sen-ice truck, garbage truck, pickup truck, or combinations of any of the preceding. The work platform 102 may be, for example, a bucket and / or a balcony. In certain examples, the work platform 102 is configured to support one or more work platform users 103, who may be utility field workers, construction workers, or the like. In certain examples, such as with cranes, the work platform 102 may be a portion of the apparatus that holds or is positioned above the portion of the apparatus that holds the work matenal. such as the trolley, jib. hook block, boom head, or hook of a mobile or stationary crane or other similar device. In the examples where work platform users 103 are one or in the work platform 102, the one or more work platform users 103 may be able to perform one or more work related tasks. For example, the one or more work platform users 103 may be able to perform one or more work related tasks associated with a utility pole 104, such as repairing equipment, replacing equipment, performing inspections, and the like. The work platform 102 is shown elevated near a utility' pole 104, indicating a typical use case for the system 100 in utility’ or construction work. During the performance of the one or more work related tasks, there is a nonzero chance that one or more objects (e.g., tools, parts, equipment, and the like) may be dropped by the one or more work platform users 103, such as the object 105. One or more ground users 106 may be at risk of injury’, should the object fall and come into contact with any portion of the one or more ground users 106.

[0032] In some aspects, the system 100 includes platform-based sensors 107 mounted on the work platform 102. These sensors may be positioned at various locations on the work platform 102, such as on the sides and / or bottom of the w ork platform 102, to define a zone 108 below and / or around the w ork platform 102. The platform-based sensors 107 are configured to detect the presence of objects, users, and / or other sensors in the zone 108. For example, an object 105, such as a tool or piece of equipment, may be detected if it falls from the work platform 102 or a portion of the MEWP or other elevated mobile or stationary’ platform below the work platform 102 (e.g., falling from a crane hook positioned below’ the jib, or hook block upon which the sensors 107 arepositioned) and into the zone 108. Similarly, a ground user 106. such as a worker or bystander on the ground, may be detected if they enter the zone 108. Similarly, a user-based sensor 109 may be detected if it enters the zone 108. The platform-based sensors 107 may employ various detection technologies, such as radar, LiDAR, passive infrared sensors, ultrasonic sensors, optical sensors, proximity sensors, cameras, temperature sensors, or RFID, to monitor the perimeter of the zone 108.

[0033] In some embodiments, the sensors may include a camera. The camera may permit object recognition capabilities, allowing the system to identify and classify different types of objects or people that enter the safety zone. This object recognition functionality may enhance the system's ability to distinguish between potentially hazardous obj ects and benign ones, potentially reducing false alarms and improving overall safety management. The camera may also permit user recognition capabilities. This feature may allow the system to identity’ specific individuals who enter the safety zone, which may be useful for tracking authorized personnel and detecting unauthorized entries. In some cases, the user recognition capabilities may be integrated with the work session data, providing detailed information about which specific personnel entered or exited the safety’ zone during a work session. In some aspects, the platform-based sensors 109 mounted on the work platform 102 may include a camera with object and user recognition capabilities. This configuration may allow for comprehensive monitoring of the area directly below’ and around the work platform 102. The camera may be able to detect and identify objects falling from the platform, as well as recognize ground users who enter the designated safety’ zone.

[0034] The signal emitted by the platform-based sensors 107 may be customized to define the boundaries of the zone 108. In some cases, the strength or characteristics of the signal may be adjusted to modify the size or shape of the zone 108 as needed for different work environments or safety’ requirements. The user-based sensors 109 and / or the cone-based sensors 114 may be calibrated to detect specific signal parameters, allowing for accurate identification of zone boundaries. One or more LEDs and / or lasers may be attached to the w ork platform 102 to visually indicate the area of the zone 108 on the surface of the ground.

[0035] In some aspects, the platform-based sensors 107 may be configured to detect the presence of other sensors within the system 100, such as the user-based sensors 109. This intersensor detection capability’ may enhance the overall monitoring and safety features of the system. For instance, the platform-based sensors 107 may be able to identity’ when a user w earing a userbased sensor 109 approaches or enters the designated safety zone.

[0036] Similarly, the user-based sensors 109 may be designed to detect the presence of the platform-based sensors 107. This two-way detection capability may provide a more comprehensive understanding of the relative positions of personnel and safety’ boundaries. Forexample, a user-based sensor 109 may alert its wearer when they are approaching the work platform 102 or entering its detection range.

[0037] In some cases, this mutual detection capability may enable more sophisticated safety protocols. The system may be able to track the movement of personnel relative to the work platform 102 with greater precision, potentially allowing for graduated alerts or responses based on proximity (e.g., proximity to the area of the zone 108). For instance, a user may receive a mild warning when approaching the work platform's vicinity and / or zone 108. and a more urgent alert if they enter a higher-risk area (e.g., enter the zone 108).

[0038] The ability of the platform-based sensors 107 and user-based sensors 109 to detect each other may also contribute to the system's adaptability in dynamic work environments. As the work platform 102 moves or is repositioned, the user-based sensors 109 may automatically recognize the new location of the platform-based sensors 107 or the zone 108 the sensors 107 monitory without the need for manual reconfiguration.

[0039] In some implementations, the detection capabilities between platform-based sensors 107 and user-based sensors 109 may extend to other sensor types within the system 100. This may include cone-based sensors 114. pole-based sensors 115. and vehicle-based sensors 116. Such a network of interconnected sensors may provide a more robust and flexible safety' monitoring system, capable of adapting to various work scenarios and environmental conditions.

[0040] In some embodiments, the platform-based sensors 107 may be configured to operate in various modes to enhance detection capabilities. For example, the sensors may switch between active and passive sensing modes depending on environmental conditions or specific work requirements. Active sensing modes may involve emitting signals and analyzing their reflections, while passive modes may rely on detecting ambient signals or changes in the environment.

[0041] The platform-based sensors 107 may also incorporate adaptive algorithms that allow them to adjust their sensitivity’ and detection parameters based on the specific characteristics of the work environment. This adaptability may enable the sensors to maintain optimal performance across different weather conditions, lighting situations, or vary ing levels of background noise and interference.

[0042] In some cases, the platform-based sensors 107 may be equipped with multiple sensing elements or technologies within a single unit. This multi-modal approach may allow for more robust and reliable detection by cross-referencing data from different sensing modalities. For instance, a sensor unit may combine infrared and ultrasonic technologies to provide comprehensive coverage and reduce false positives.

[0043] In some aspects, the platform-based sensors 107 may be designed with modular components, allowing for easy maintenance, upgrades, or replacements of individual sensorelements without the need to replace the entire sensor unit. This modularity may also facilitate customization of the sensor array for specific work environments or safety requirements.

[0044] The mounting mechanisms for the platform-based sensors 107 may incorporate shockabsorbing and vibration-dampening features to ensure stable and accurate readings even when the work platform 102 is in motion or subjected to external forces. These mounting systems may also be designed to protect the sensors from environmental factors such as dust, moisture, or extreme temperatures.

[0045] Tn some embodiments, the system 100 may include one or more user-based sensors 109 that are configured to be affixed or positioned on users. The user-based sensors 109 may be designed to detect a signal emitted by the platform-based sensors 107. This configuration allows the user-based sensors 109 to determine when they have entered the zone 108. For example, when a user wearing a user-based sensor 109 enters the zone 108, the user-based sensor 109 may detect the signal from the platform-based sensors 107, indicating that the user has entered the monitored area. This approach may provide a more precise method of detecting when personnel have entered the safety zone around the work platform 102. The user-based sensors 109 may employ various detection technologies, such as radar. LiDAR. passive infrared sensors, ultrasonic sensors, cameras, optical sensors, proximity sensors, temperature sensors, or RFID, to monitor for the perimeter of the zone 108.

[0046] In some cases, the system 100 also includes user-based sensors 109 that may be affixed to personal equipment of the work platform users 103. For instance, a user-based sensor 109 may be affixed to clothing or a hat (e g., a hard hat 110) worn by a work platform user 103. The userbased sensors 109 are configured to detect when the user-based sensors 109 have entered the zone 108, triggering an alarm to alert the work platform users 103 and the ground users 106 of potential hazards.

[0047] In some embodiments, a user device 111, such as a smartphone, may be configured to serve a similar function as a user-based sensor 109. The user device 111 may be carried or worn by the work platform users 103 or the ground users 106, and may be configured to detect when the user device 111 has entered and / or is nearing the zone 108.

[0048] In some aspects, the user-based sensors 109 may be designed with various form factors to accommodate different attachment methods and user preferences. For example, the sensors may be integrated into wearable devices such as wristbands, badges, or clip-on units that can be easily attached to clothing or personal protective equipment. This flexibility in design may allow for seamless integration into existing work attire and equipment.

[0049] The user-based sensors 109 may incorporate multiple sensing technologies to enhance their detection capabilities. In addition to detecting signals from the platform-based sensors 107,they may include accelerometers, gyroscopes, altimeters, or global positioning systems (GPS) to track the user's movement and position. This multi-sensor approach may provide more accurate information about the user's location relative to the safety zone.

[0050] In some cases, the user-based sensors 109 may be equipped with wireless communication capabilities, allowing them to transmit real-time data to the computing device 117. This feature may enable continuous monitoring of personnel locations and immediate alerts if a user enters the safety zone. The wireless communication may utilize various protocols such as Bluetooth, Wi-Fi, or cellular networks, depending on the specific requirements and capabilities of the work environment.

[0051] The user-based sensors 109 may also include built-in display screens or haptic feedback mechanisms to provide immediate visual or tactile alerts to the user. For instance, the sensor may vibrate or flash a warning light when the user approaches and / or enters the boundary of the safety zone 108, providing an additional layer of protection against accidental entry.

[0052] In some embodiments, the user-based sensors 109 may be designed with long-lasting, rechargeable batteries to ensure continuous operation throughout extended work shifts. The sensors may also feature low-power modes or smart power management systems to optimize battery life while maintaining essential functionality.

[0053] The user-based sensors 109 may be programmed with unique identifiers for each user, allowing the system to track and log individual entries and exits from the safety zone. This feature may be useful for compliance monitoring, safety audits, and personalized safety training.

[0054] The user-based sensors 109 affixed or positioned on the workers may also incorporate a camera in some implementations. This camera may provide a first-person perspective of the work environment, potentially capturing valuable data about the worker's activities and surroundings. The object and user recognition capabilities of this camera may assist in identifying potential hazards or safety violations from the worker's point of view.

[0055] In some aspects, the platform-based sensors 107 may be configured to detect the presence of other sensors within the system 100, such as the user-based sensors 109. This intersensor detection capability may enhance the overall monitoring and safety features of the system. For instance, the platform-based sensors 107 may be able to identify when a user wearing a userbased sensor 109 approaches or enters the designated safety zone 108.

[0056] Similarly, the user-based sensors 109 may be designed to detect the presence of the platform-based sensors 107. This two-way detection capability may provide a more comprehensive understanding of the relative positions of personnel and safety boundaries. For example, a user-based sensor 109 may alert its wearer when they are approaching the work platform 102 or zone 108 or entering its detection range.

[0057] In some cases, this mutual detection capability7may enable more sophisticated safety7protocols. The system may be able to track the movement of personnel relative to the work platform 102 with greater precision, potentially allowing for graduated alerts or responses based on proximity^. For instance, a user may receive a mild warning when approaching the zone 108 or work platform's vicinity7, and a more urgent alert if they enter the zone 108 or another higher-risk area.

[0058] The ability of the platform-based sensors 107 and user-based sensors 109 to detect each other may' also contribute to the system's adaptability7in dynamic work environments. As the work platform 102 moves or is repositioned, the user-based sensors 109 may automatically recognize the new location of the platform-based sensors 107 and / or zone 108 without the need for manual reconfiguration.

[0059] In some implementations, the detection capabilities between platform-based sensors 107 and user-based sensors 109 may extend to other sensor types within the system 100. This may include cone-based sensors 114, pole-based sensors 115, and vehicle-based sensors 116. Such a network of interconnected sensors may provide a more robust and flexible safety monitoring system, capable of adapting to various work scenarios and environmental conditions.

[0060] In some aspects, the system 100 includes safety cones, pylons, or devices (hereinafter generally referred to as safety7cones 112) positioned at the perimeter of the zone 108. The safety7cones 112 may include indicators 113, such as lights, LEDs or other visual signals, to visually mark the perimeter of the zone 108. In some cases, the safety cones 112 may also include conebased sensors 114, which are configured to detect when an object and / or a user has breached the perimeter of the zone 108. In an embodiment, the one or more cone-based sensors 114 may be configured to project the zone 108 upwards toward the work platform 102, for example, toward a designated area on the work platform 102 such as a reflective portion. The cone-based sensors 114 may employ various detection technologies, such as radar, LiDAR, passive infrared sensors, optical sensors, proximity sensors, ultrasonic sensors, cameras, temperature sensors, or RFID, to monitor the perimeter of the zone 108.

[0061] In some aspects, the cone-based sensors 114 may be designed with a low-profile form factor to integrate seamlessly with the safety cones 112. This integration may allow for easy deployment and relocation of the sensors as the work area changes. The cone-based sensors 114 may be powered by rechargeable batteries, solar panels, or a combination of both, enabling extended operation without the need for frequent maintenance.

[0062] The cone-based sensors 114 may incorporate multiple sensing technologies to provide comprehensive coverage of the perimeter. For example, they may combine infrared sensors fordetecting body heat with ultrasonic sensors for measuring distance. This multi-modal approach may enhance the accuracy of detection and reduce false alarms.

[0063] In some cases, the cone-based sensors 114 may be equipped with wireless communication capabilities, allowing the sensors 114 to form a mesh network around the work area. This network may enable the sensors to communicate with each other and with the central computing device 117, providing real-time updates on the status of the perimeter and any breaches detected.

[0064] The cone-based sensors 114 may also feature adaptive algorithms that allow them to adjust their sensitivity based on environmental conditions. For instance, the sensors 114 may automatically calibrate their detection thresholds to account for changes in ambient light, temperature, or background noise levels. This adaptability may help maintain consistent performance across various work environments and weather conditions.

[0065] The cone-based sensors 114 may be designed with modular components, allowing for easy replacement or upgrade of individual parts. This modularity may extend the lifespan of the sensors and facilitate the integration of new sensing technologies as they become available. In certain embodiments, the cone-based sensors may be intergral with the corresponding safety cone 112

[0066] In some aspects, the cone-based sensors 114 may be equipped with visual and audible alert systems. These may include high- visibility lighting, such as LEDs, that flash when a breach is detected, as well as speakers that emit warning tones. The intensity and pattern of these alerts may be customizable to suit different work environments and safety protocols.

[0067] In some cases, the cone-based sensors 114 integrated with safety cones 112 may include a camera with object and user-recognition capabilities. This may allow for more accurate monitoring of the perimeter of the safety zone 108. with the ability to distinguish between different types of objects or users that breach the perimeter.

[0068] In some aspects, the system 100 may include pole-based sensors 115 affixed to the utility pole 104 or other work area. The pole-based sensors 115 may be positioned at various heights along the utility pole 104 or work areato monitor the zone 108 around the work platform 102. These sensors may be configured to detect the presence of objects, users, and other sensors within the monitored area.

[0069] The pole-based sensors 115 may employ various detection technologies, such as radar, LiDAR, passive infrared sensors, proximity sensors, optical sensors, ultrasonic sensors, cameras, temperature sensors, or RFID, to monitor the zone 108. In some cases, the pole-based sensors 115 may be designed to work in conjunction with the platform-based sensors 107, user-based sensors 109, and / or cone-based sensors 114 to provide comprehensive coverage of the w ork area.

[0070] The positioning of the pole-based sensors 115 on the utility7pole 104 may offer unique advantages in monitoring the zone 108. For instance, these sensors 115 may provide a different perspective on the work area, potentially detecting objects or users that might be obscured from the view of other sensors in the system. The pole-based sensors 115 may also be useful in monitoring the movement of the work platform 102 itself, helping to prevent collisions between the platform and the utility pole 104 or other nearby structures.

[0071] In some embodiments, the pole-based sensors 115 may be temporarily installed on the utility pole 104 or other work area for the duration of the work session. This may allow for flexibility' in setting up the safety' system at different work sites. Alternatively, in locations where work is frequently performed, the pole-based sensors 115 may be permanently installed on utility7poles or other work areas to provide consistent safety monitoring.

[0072] The data collected by the pole-based sensors 115 may be transmitted to the computing device 117, where it can be integrated with data from other sensors in the system 100. This integrated data may provide a more complete picture of the work environment, enhancing the overall safety7of the operation.

[0073] The pole-based sensors affixed to structures being accessed by the work platform may also incorporate a camera in some embodiments. This camera may provide a unique vantage point for monitoring the work area, with object and user recognition capabilities enhancing the system's ability to detect and identify potential safety hazards from multiple angles.

[0074] In some aspects, the system 100 may include vehicle-based sensors 116 affixed to the mobile elevating work platform (MEWP) 101. The vehicle-based sensors 116 may be strategically positioned at various locations on the MEWP 101, such as on the base, boom, or other structural components, to provide comprehensive coverage of the surrounding area. These sensors may be configured to detect the presence of objects, users, and other sensors within the monitored zone 108

[0075] The vehicle-based sensors 116 may' employ a variety' of detection technologies, including radar, LiDAR, passive infrared sensors, proximity sensors, optical sensors, ultrasonic sensors, cameras, temperature sensors, or RFID. In some cases, the vehicle-based sensors 116 may utilize multiple sensing modalities to enhance their detection capabilities and reduce the likelihood of false positives.

[0076] The positioning of the vehicle-based sensors 116 on the MEWP 101 may offer several advantages in monitoring the work area. For instance, these sensors may provide a wider field of view compared to the platform-based sensors 107. potentially detecting objects or users at greater distances from the work platform 102. The vehicle-based sensors 116 may also be useful inmonitoring the movement and stability of the MEWP 101 itself, helping to prevent tip-overs or collisions with nearby structures or obstacles.

[0077] In some embodiments, the vehicle-based sensors 116 may be designed with ruggedized housings to withstand the harsh conditions often encountered in construction and maintenance environments. These housings may provide protection against dust, moisture, vibration, and impacts, ensuring reliable operation of the sensors in various weather conditions and work scenarios.

[0078] The vehicle-based sensors 116 may incorporate adaptive algorithms that allow them to adjust their sensitivity and detection parameters based on the specific characteristics of the work environment. This adaptability may enable the sensors to maintain optimal performance across different terrains, lighting conditions, or varying levels of background noise and interference.

[0079] In some cases, the vehicle-based sensors 116 may be equipped with wireless communication capabilities, allowing them to transmit real-time data to the computing device 117. This feature may enable continuous monitoring of the w ork area and immediate alerts if potential hazards are detected. The wireless communication may utilize various protocols such as Bluetooth, Wi-Fi, or cellular networks, depending on the specific requirements of the work environment and the range of coverage needed.

[0080] In some aspects, the vehicle-based sensors 116 may be integrated with the MEWP's control systems. This integration may allow the sensors 116 to provide input for automated safety features, such as motion control or emergency stop functions, enhancing the overall safety of the MEWP operation.

[0081] The data collected by the vehicle-based sensors 116 may be combined with data from other sensors in the system 100, such as the platform-based sensors 107, user-based sensors 109, cone-based sensors 114, and / or pole-based sensors 115. This multi-sensor approach may provide a more comprehensive and accurate assessment of the work environment, potentially identifying hazards or safety issues that might be missed by a single sensor type.

[0082] In some implementations, the vehicle-based sensors 116 affixed to the MEWP may include a camera with object and user recognition capabilities. This may allow for comprehensive monitoring of the area around the MEWP, potentially detecting obstacles or personnel that may not be visible from the work platform itself.

[0083] An audible, visual, and / or tactile alarm may be triggered responsive to the sensing of the presence of an object, a user, and / or a sensor in the zone 108. The one or more work platform users 103 and the one or more ground users 106 may be alerted before a collision and / or injury occurs. The audible, visual, and / or tactile alarm may be generated by any suitable device. In someembodiments, the audible, visual, and / or tactile alarm may be generated by a device worn or possessed by the one or more work platform users 103 and the one or more ground users 106.

[0084] In some embodiments, the system 100 may include a computing device 117 in communication with the various sensors. The computing device 117 may be configured to receive sensor data from the platform-based sensors 107, user-based sensors 109, user device 111, and / or cone-based sensors 114, and to generate work session data based on the received sensor data. This work session data may provide valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106. Work session data may include, but is not limited to, the establishment of the safety system (e.g., the sensor system 100), a quantity of entries into the zone (e g., the zone 108), a quantity of exits from the zone (e g., the zone 108), an identification of personnel associated with the zone (including but not limited to, a quantity of entries associated with identified personnel, a quantity of exits associated with identified personnel, a duration of time associated with each entry associated with identified personnel, a cumulative duration of time within the zone associated with identified personnel, combinations thereof, and the like), associated time and / or date information, geolocation information, worksite information, environmental conditions (e.g., weather, temperature, and the like), video, images, audio, combinations thereof and the like.

[0085] The computing device 117, in communication with the sensors in the form of cameras, may process the video and / or image data from these cameras, utilizing advanced algorithms for object and user recognition. This processing may occur in real-time, allowing for immediate alerts and responses to potential safety hazards. The object and user recognition data may also be incorporated into the work session data, providing detailed information about the types of objects and specific users detected during each work session, including which user entered / exited the zone and when.

[0086] Referring to FIG. IB, the system 100 is depicted with platform-based sensors 107 mounted underneath or along the bottom side of the work platform 102. In some aspects, this configuration allows for enhanced detection of objects or users in the zone 108 directly below the work platform 102. The platform-based sensors 107 may be strategically positioned to cover at least the entire area underneath the work platform 102. providing comprehensive monitoring of the zone 108. For examples where the device is a crane or similar device, the sensors 107 may be positioned underneath or along the bottom side of the work platform, such as the trolley,jib, hook block, boom head, or hook block.

[0087] In some cases, the platform-based sensors 107 may be affixed to the underside of the work platform 102 using various mounting mechanisms. For instance, the platform-based sensors 107 may be attached directly to the work platform 102 or may be mounted on brackets or othersupporting structures affixed to the underside of the work platform 102. The platform-based sensors 107 may be configured to detect the presence of objects, such as tools or equipment, that may fall from the work platform 102 into the zone 108. In some embodiments, the platform-based sensors 107 may also be configured to detect the presence of ground users 106 entering the zone 108. In some aspects, the platform-based sensors 107 may be configured to detect not only objects, but users and / or user-based sensors 109 within the zone 108. This expanded detection capability may enhance the overall safety monitoring of the work area. The platform-based sensors107 may utilize various technologies such as infrared, ultrasonic, optical, or radio frequency identification (RFID) to identify and track the presence of users and user-based sensors 109 in the monitored zone 108. In some cases, the platform-based sensors 107 may be programmed to distinguish between different types of entities in the zone 108. For example, the sensors 107 may be able to differentiate between inanimate objects, human users, and user-based sensors 109. This differentiation may allow for more nuanced safety protocols and alerts based on the specific type of entity detected in the zone.

[0088] In some aspects, the platform-based sensors 107 may be configured to detect the presence of other sensors within the system 100, such as the user-based sensors 109. This intersensor detection capability may enhance the overall monitoring and safety features of the system. For instance, the platform-based sensors 107 may be able to identify when a user wearing a userbased sensor 109 approaches or enters the designated safety zone 108.|0089| Similarly, the user-based sensors 109 may be designed to detect the presence of the platform-based sensors 107. This two-way detection capability may provide a more comprehensive understanding of the relative positions of personnel and safety boundaries. For example, a user-based sensor 109 may alert its wearer when they are approaching the work platform 102 or zone 108 and / or entering its detection range (e.g., the zone 108).

[0090] In some cases, this mutual detection capability may enable more sophisticated safety protocols. The system may be able to track the movement of personnel relative to the work platform 102 with greater precision, potentially allowing for graduated alerts or responses based on proximity. For instance, a user may receive a mild warning when approaching the work zone108 or work platform's vicinity, and a more urgent alert if they enter a higher-risk area, such as the work zone 108.

[0091] The ability7of the platform-based sensors 107 and user-based sensors 109 to detect each other may also contribute to the system's adaptability in dynamic work environments. As the work platform 102 moves or is repositioned, the user-based sensors 109 may automatically recognize the new location of the platform-based sensors 107 and / or zone 108 without the need for manual reconfiguration.

[0092] In some implementations, the detection capabilities between platform-based sensors 107 and user-based sensors 109 may extend to other sensor types within the system 100. This may include cone-based sensors 114, pole-based sensors 115, and / or vehicle-based sensors 116. Such a network of interconnected sensors may provide a more robust and flexible safety monitoring system, capable of adapting to various work scenarios and environmental conditions.

[0093] The platform-based sensors 107 may also be configured to communicate with userbased sensors 109 when the user-based sensors 109 enter the zone 108. This communication may enable the system to identify specific individuals, track their movements within the zone 108, and potentially provide personalized safety' alerts or instructions. In some embodiments, the detection of users and user-based sensors 109 by the platform-based sensors 107 may be integrated with the work session data generated by the computing device 117. This integration may provide more detailed information about personnel movements and interactions within the work area, potentially improving safety management and workflow optimization.

[0094] Upon detecting an object or a user approaching and / or in the zone 108, the platformbased sensors 107 may trigger an alarm to alert the work platform users 103 and / or the ground users 106 of potential hazards. The alarm may be audible, visual, or tactile, providing immediate alerts to potential safety hazards.

[0095] In some embodiments, the platform-based sensors 107 may be in communication with a computing device 117, which may be configured to receive sensor data from the platform-based sensors 107, process the sensor data, and generate work session data based on the received sensor data. The work session data may provide valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106.

[0096] In some cases, the platform-based sensors 107 mounted underneath the work platform 102 may be used in combination with other sensors in the system 100, such as user-based sensors 109, cone-based sensors 114, pole-based sensors 115, and vehicle-based sensors 116, to provide comprehensive monitoring of the work area and its surroundings.

[0097] Referring to FIG. 1C, the system 100 is depicted with cone-based sensors 114 integrated with safety cones 112. In some aspects, the safety cones 112 are positioned at the perimeter of the zone 108. marking the boundary of the safety zone. The cone-based sensors 114 are configured to detect when an object and / or a user has breached the perimeter of the zone 108. In some cases, the cone-based sensors 114 may be of the same or different type as the platformbased sensors 107. The cone-based sensors 114 may employ various detection technologies, such as radar, LiDAR, passive infrared sensors, ultrasonic sensors, cameras, temperature sensors, or RFID, to monitor the perimeter of the zone 108. Upon detecting an object or a user breaching the perimeter of the zone 108, the cone-based sensors 114 may trigger an alarm to alert the workplatform users 103 and the ground users 106 of potential hazards. The alarm may be audible, visual, or tactile, providing immediate alerts to potential safety hazards.

[0098] In some aspects, the cone-based sensors 114 may be configured to detect other sensors within the system 100, such as the user-based sensors 109. This inter-sensor detection capability may enhance the overall monitoring and safety features of the system. For instance, the conebased sensors 114 may be able to identify when a user wearing a user-based sensor 109 approaches or enters the designated safety zone.

[0099] Similarly, the user-based sensors 109 may be designed to detect the presence of the cone-based sensors 114. This two-way detection capability may provide a more comprehensive understanding of the relative positions of personnel and safety boundaries. For example, a userbased sensor 109 may alert its wearer when they are approaching the perimeter marked by the cone-based sensors 114.

[0100] In some cases, this mutual detection capability may enable more sophisticated safety protocols. The system may be able to track the movement of personnel relative to the safety7zone boundaries with greater precision, potentially allowing for graduated alerts or responses based on proximity. For instance, a user may receive a mild warning when approaching the zone perimeter, and a more urgent alert if they actually cross the boundary.

[0101] The ability of the cone-based sensors 114 and user-based sensors 109 to detect each other may also contribute to the system's adaptability in dynamic work environments. As safetycones are moved to redefine work areas, the user-based sensors 109 may automatically recognize the new boundaries without the need for manual reconfiguration.

[0102] In some implementations, the detection capabilities between cone-based sensors 114 and user-based sensors 109 may extend to other sensor types within the system 100. This may include platform-based sensors 107, pole-based sensors 115, and vehicle-based sensors 116. Such a network of interconnected sensors may provide a more robust and flexible safety monitoring system, capable of adapting to various work scenarios and environmental conditions.

[0103] In some aspects, the cone-based sensors 114 may be configured to create a virtual perimeter around the work area. This virtual perimeter may be established by the placement of the safety cones 112 equipped with the cone-based sensors 114. The cone-based sensors 114 may utilize various sensing technologies to detect when an object or person crosses this virtual boundary7.

[0104] When the cone-based sensors 114 detect a breach of the perimeter, they may immediately raise an alert. This alert may be communicated to the computing device 117. which may then trigger appropriate responses. The alert may also be directly communicated to nearby workers through audible, visual, or tactile means.

[0105] In some cases, the cone-based sensors 114 may be capable of distinguishing between different types of perimeter breaches. For example, they may differentiate between a person entering the zone and an object falling into the zone. This differentiation may allow for more specific and appropriate responses to each type of breach.

[0106] The perimeter created by the cone-based sensors 114 may be dynamically adjustable. As the work area changes or the MEWP 101 or other elevated mobile or stationary platform moves, the safety cones 112 and their associated sensors may be repositioned to create a new perimeter. The system 100 may automatically recognize this new configuration and adjust its monitoring accordingly.

[0107] In some aspects, the cone-based sensors 114 may be configured to project the zone 108 upwards toward the work platform 102. This upward projection may target specific surfaces on the work platform 102 that may be designated for such purpose. For example, certain areas of the work platform 102 may be equipped with reflective materials or specially designed surfaces to interact with the projected zone from the cone-based sensors 114.

[0108] In some cases, this upward projection capability may allow the cone-based sensors 114 to create a three-dimensional safety zone that extends from the ground level up to the work platform 102. This may provide more comprehensive coverage of the entire work area, including the space betw een the ground and the elevated work platform.

[0109] The cone-based sensors 114 may utilize various technologies to achieve this upward projection, such as infrared beams, laser scanning, or ultrasonic waves. These technologies may be selected based on their ability to accurately define the boundaries of the zone 108 in three- dimensional space and their effectiveness in different environmental conditions.

[0110] In some implementations, the upward projection from the cone-based sensors 114 may be dynamically adjusted based on the height of the work platform 102. For example, as the MEWP 101 raises or lowers the work platform 102, the cone-based sensors 114 may automatically adjust their projection to maintain consistent coverage of the safety zone.

[0111] The interaction between the upward-projected zone and the designated surfaces on the work platform 102 may provide additional data points for the system 100. For instance, any interruption or distortion in the projected zone may be detected and interpreted as a potential hazard, such as an object falling from the work platform or an unauthorized entry into the safety zone.

[0112] In some embodiments, the cone-based sensors 114 may work in conjunction with other sensor types in the system 100 to provide comprehensive coverage of the work area. For instance, they may communicate with the platform-based sensors 107 or the vehicle-based sensors116 to create a multi-layered detection system, enhancing the overall safety of the work environment.

[0113] In some embodiments, the cone-based sensors 114 may be connected to a computing device 117, which may be configured to receive sensor data from the cone-based sensors 114, process the sensor data, and generate work session data based on the received sensor data. The work session data may provide valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106.

[0114] Tn some aspects, the cone-based sensors 114 may be used in combination with other sensors in the system 100, such as platform-based sensors 107, user-based sensors 109, pole-based sensors 115, and vehicle-based sensors 116, to provide comprehensive monitoring of the work area and its surroundings.

[0115] In some cases, the cone-based sensors 114 may be integrated with indicators 113, such as LEDs or other visual signals, to visually mark the perimeter of the zone 108. This visual indication of the zone 108 may provide an additional layer of safety, alerting ground users 106 to the presence of the safety zone before they breach the perimeter.

[0116] In some embodiments, the cone-based sensors 114 may be affixed to the safety cones 112 in various ways. For instance, the cone-based sensors 114 may be attached directly to the safety7cones 112 or may be mounted on brackets or other supporting structures affixed to the safety cones 112. This flexibility in mounting options allows for the cone-based sensors 114 to be positioned optimally for detecting objects or users breaching the perimeter of the zone 108.

[0117] Referring to FIG. ID, the system 100 is depicted with pole-based sensors 115 affixed to a utility pole 104. In some aspects, the utility' pole 104 is a structure that is being accessed by the work platform 102. The pole-based sensors 115 may be of the same or different type as the platform-based sensors 107.

[0118] In some aspects, the pole-based sensors 115 may represent any type of sensor that may be affixed to a structure being accessed by the work platform 102. While the utility' pole 104 is shown as an example, these sensors may be attached to various structures such as buildings, bridges, towers, or any other elevated structure where the MEWP 101 or other elevated mobile or stationary platform may be utilized. The pole-based sensors 115 may be temporarily or permanently installed on these structures to enhance the safety monitoring capabilities of the system 100.

[0119] In some cases, the pole-based sensors 115 may be positioned at various heights along the structure to provide comprehensive coverage of the work area. These sensors may employ different detection technologies, such as infrared, ultrasonic, or radio frequency, depending on the specific requirements of the w ork environment and the nature of the structure.

[0120] The pole-based sensors 115 may be configured to communicate with other components of the system 100, such as the computing device 117 or other sensor types. This integration may allow for a more robust detection network, potentially identifying hazards or safety issues that might be missed by sensors mounted only on the work platform 102 or on ground-based equipment.

[0121] In some implementations, the pole-based sensors 115 may be designed with weatherproof housings and power systems that allow for extended operation in various environmental conditions. They may also feature adjustable mounting mechanisms to facilitate optimal positioning on different types of structures.

[0122] In some cases, the pole-based sensors 115 are positioned to define the zone 108. The pole-based sensors 115 may be configured to detect the presence of objects and / or users in the zone 108. For example, an object 105, such as a tool or piece of equipment, may be detected if it falls from the work platform 102 into the zone 108. Similarly, a ground user 106 may be detected if they enter the zone 108.

[0123] In some aspects, the pole-based sensors 115 may be configured to detect the presence of other sensors within the system 100. For instance, the pole-based sensors 115 may be able to detect and communicate with user-based sensors 109 worn by work platform users 103 or ground users 106. This capability7may allow the system to track the location of personnel relative to the utility pole 104 and the defined safety zones.

[0124] Similarly, the user-based sensors 109 may be designed to detect the presence of the pole-based sensors 115. This two-way detection capability may enhance the overall safety monitoring by providing redundancy and cross-verification of sensor data. For example, if a userbased sensor 109 approaches the utility pole 104, both the user-based sensor 109 and the polebased sensors 115 may register this event, potentially triggering alerts through multiple channels.

[0125] In some cases, the pole-based sensors 115 may also be able to detect and communicate with other types of sensors in the system 100, such as the platform-based sensors 107, cone-based sensors 114, and vehicle-based sensors 116. This inter-sensor communication may allow for a more comprehensive and integrated monitoring system, potentially improving the accuracy of hazard detection and reducing false alarms.

[0126] The ability' of different sensor types to detect each other may also facilitate the system's adaptability to changing work environments. As the MEWP 101 or other elevated mobile or stationary platform moves or the work area configuration changes, the sensors may automatically adjust their detection parameters based on their relative positions to maintain optimal coverage of the safety zones.

[0127] Upon detecting an object or a user in the zone 108, the pole-based sensors 115 may trigger an alarm to alert the work platform users 103 and the ground users 106 of potential hazards. The alarm may be audible, visual, or tactile, providing immediate alerts to potential safety hazards.

[0128] In some embodiments, the pole-based sensors 115 may be connected to a computing device 117, which may be configured to receive sensor data from the pole-based sensors 115, process the sensor data, and generate work session data based on the received sensor data. The work session data may provide valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106.

[0129] In some aspects, the pole-based sensors 115 may be used in combination with other sensors in the system 100, such as platform-based sensors 107, user-based sensors 109, conebased sensors 114. and vehicle-based sensors 116, to provide comprehensive monitoring of the work area and its surroundings.

[0130] In some cases, the pole-based sensors 115 may be affixed to the utility pole 104 in various ways. For instance, the pole-based sensors 115 may be attached directly to the utility pole 104 or may be mounted on brackets or other supporting structures affixed to the utility pole 104. This flexibility in mounting options allows for the pole-based sensors 115 to be positioned optimally for detecting objects or users in the zone 108.

[0131] Referring to FIG. IE, the system 100 is depicted with vehicle-based sensors 116 affixed to the mobile elevating work platform (MEWP) 101 or base portion of an elevated platform. In some aspects, the vehicle-based sensors 116 may be mounted on various parts of the MEWP 101 or other base portion of an elevated platform, such as the body, the boom, the outriggers, or any other suitable part of the MEWP 101 or other elevated platform. The vehiclebased sensors 116 may be configured to detect the presence of objects and / or users in the zone 108.

[0132] For example, an object 105, such as a tool or piece of equipment, may be detected if it falls from the work platform 102 into the zone 108. Similarly, a ground user 106 may be detected if they enter the zone 108. The vehicle-based sensors 116 may employ various detection technologies, such as radar, LiDAR, passive infrared sensors, ultrasonic sensors, cameras, temperature sensors, or RFID, to monitor the zone 108.

[0133] In some aspects, the vehicle-based sensors 116 may be configured to detect the presence of other sensors within the system 100. For instance, the vehicle-based sensors 116 may be able to detect and communicate with user-based sensors 109 worn by work platform users 103 or ground users 106. This capability may allow the system to track the location of personnel relative to the MEWP 101 and the defined safety zones.

[0134] Similarly, the user-based sensors 109 may be designed to detect the presence of the vehicle-based sensors 116. This two-way detection capability may enhance the overall safetv’ monitoring by providing redundancy and cross-verification of sensor data. For example, if a userbased sensor 109 enters a safety zone, both the user-based sensor 109 and the vehicle-based sensors 116 may register this event, potentially triggering alerts through multiple channels.

[0135] In some cases, the vehicle-based sensors 116 may also be able to detect and communicate with other types of sensors in the system 100, such as the platform-based sensors 107, cone-based sensors 114, and pole-based sensors 115. This inter-sensor communication may allow for a more comprehensive and integrated monitoring system, potentially improving the accuracy of hazard detection and reducing false alarms.

[0136] The ability’ of different sensor types to detect each other may also facilitate the system's adaptability to changing work environments. As the MEWP 101 moves or the work area configuration changes, the sensors may automatically adjust their detection parameters based on their relative positions to maintain optimal coverage of the safety zones.

[0137] Upon detecting an object or a user in the zone 108, the vehicle-based sensors 116 may trigger an alarm to alert the work platform users 103 and the ground users 106 of potential hazards. The alarm may be audible, visual, or tactile, providing immediate alerts to potential safety hazards.

[0138] In some embodiments, the vehicle-based sensors 116 may be connected to a computing device 117, which may be configured to receive sensor data from the vehicle-based sensors 116, process the sensor data, and generate work session data based on the received sensor data. The work session data may provide valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106.

[0139] In some aspects, the vehicle-based sensors 116 may be used in combination with other sensors in the system 100, such as platform-based sensors 107. user-based sensors 109. conebased sensors 114, and pole-based sensors 115, to provide comprehensive monitoring of the work area and its surroundings.

[0140] In some cases, the vehicle-based sensors 116 may be affixed to the MEWP 101 in various ways. For instance, the vehicle-based sensors 116 may be attached directly to the MEWP 101 or may be mounted on brackets or other supporting structures affixed to the MEWP 101. This flexibility in mounting options allows for the vehicle-based sensors 116 to be positioned optimally for detecting objects or users in the zone 108.

[0141] Referring to FIG. IF, the system 100 is depicted utilizing multiple types of sensors to generate a plurality of zones, enhancing the overall coverage and protection around the work area. In some aspects, the system 100 may include platform-based sensors 107, user-based sensors 109, cone-based sensors 114, pole-based sensors 115, and vehicle-based sensors 116. These sensorsmay be strategically positioned on the work platform 102, the MEWP 101, the safety cones 112, the utility pole 104, and the personnel's equipment, respectively.

[0142] In some cases, the platform-based sensors 107, user-based sensors 109, cone-based sensors 114, pole-based sensors 115, and vehicle-based sensors 116 may be configured to define a first zone 118 and a second zone 119. The first zone 118 may be defined by the platform-based sensors 107 and the user-based sensors 109, while the second zone 119 may be defined by the cone-based sensors 114. This arrangement allows for overlapping safety zones, providing comprehensive coverage of the work area and its surroundings.

[0143] In some embodiments, the first zone 118 and the second zone 119 may overlap, creating an area of enhanced safety coverage. This overlapping area may provide a buffer zone where both the platform-based sensors 107 and the cone-based sensors 114 are active, increasing the likelihood of detecting objects or users in this area.

[0144] In some aspects, the first zone 118 and the second zone 119 may be dynamically adjustable based on the position and orientation of the work platform 102, the MEWP 101, and the safety cones 112. For instance, the zones 118, 119 may expand or contract, or shift in position, in response to movements of the work platform 102 or the MEWP 101. This dynamic adjustability allows the system 100 to maintain optimal safety coverage as the work environment changes.

[0145] In some aspects, the use of multiple zones and overlapping zones in the system 100 may provide additional advantages for enhancing safety and operational efficiency. The first zone 118 and second zone 119 may be configured with different sensitivity levels or detection parameters, allowing for graduated responses based on the proximity of objects or personnel to the work platform 102 or MEWP 101. For example, the first zone 118 may trigger a warning alert when an object or user enters its perimeter, while the second zone 119 may initiate an immediate stop of operations if breached.

[0146] The overlapping areas between zones may serve as transition regions, potentially allowing for more nuanced safety protocols. In some cases, these overlapping areas may enable the system to track the direction and speed of objects or personnel moving between zones, providing valuable data for risk assessment and predictive safety measures.

[0147] Multiple zones may also allow for customization of safety parameters based on specific work tasks or environmental conditions. For instance, the system 100 may be configured to adjust the size or shape of zones 118 and 119 depending on the type of work being performed, the height of the work platform 102, or the presence of specific hazards in the work area.

[0148] In some implementations, the use of multiple zones may facilitate differentiated access control for various types of personnel. For example, the system 100 may be configured to allowcertain authorized personnel to enter the second zone 119 without triggering an alarm, while still maintaining strict access control for the first zone 118 closest to the work platform 102.

[0149] The combination of multiple zones and various sensor types may also enhance the system's abil i ty to filter out false positives. By cross-referencing data from different zones and sensor types, the system 100 may more accurately distinguish between genuine safety threats and benign events, potentially reducing unnecessary work stoppages while maintaining a high level of safety.

[0150] Tn some aspects, the multiple zone configuration may support more sophisticated data logging and analysis capabilities. The computing device 117 may process data from different zones separately or in combination, potentially providing more detailed insights into work patterns, safety compliance, and potential areas for improvement in safety protocols.

[0151] In some cases, the system 100 may include a computing device 117 configured to receive sensor data from the platform-based sensors 107, user-based sensors 109, cone-based sensors 114, pole-based sensors 115, and vehicle-based sensors 116. The computing device 117 may process the sensor data to determine the boundaries of the first zone 118 and the second zone 119, and to detect the presence of objects or users within these zones. The computing device 117 may also generate work session data based on the received sensor data, providing valuable information about the safety of the work environment and the behavior of the work platform users 103 and ground users 106.[0152| Referring to FIG. 2. a system 200 is depicted.

The one or more displays may display, for example, a variety of contents (e.g., text, image, video, icon, symbol, etc.) to a user.

[0156] The interface module 237 may include, be associated with, and / or be in communication with a graphical user interface (GUI), a web browser (e.g., Internet Explorer®, Mozilla Firefox®, Google Chrome®, Safari®, or the like), an application / API. The interface module 237 may request and / or query various files from a local source such as the memory 236 and / or a remote source, such as computing device 117 and / or a user device 111 (e.g.. a smart device, a laptop / computer. etc.). Although only one computing device 117 and one user device 111 are shown, the system 200 may include any number of computing devices and user devices.

[0157] The communication module 238 may establish, for example, communication betw een the server 220 and any other de vice / component of the system 200, such as the computing device(s) 117, and / or the user device 111. The communication module 238 may utilize any suitable wired communication technique, such as Ethernet, coaxial cable, fiber optics, and / or the like. The communication module 238 may utilize any suitable long-range communication technique, suchas Wi-Fi (IEEE 802.11), BLUETOOTH®, cellular, satellite, infrared, and / or the like. The communication module 238 may utilize any suitable short-range communication technique, such as BLUETOOTH®, near-field communication, infrared, and the like.

[0158] The memory 236 may include a volatile and / or non-volatile memory. The memory 236 may store, for example, a command and / or data related to at least one different constitutional element of server 220. The memory 236 may store software, such as an application and / or a program 250. The program 250 may be configured for construct identification and analysis. The program 250 may include, for example, a kernel 251, middleware 252, an Application Programming Interface (API) 253, a data logging module 254, a data processing and analysis module 255, and / or the like.

[0159] At least one part of the kernel 251, middleware 252, or API 253 may be referred to as an Operating System (OS). The memory 236 may include a non-transitory computer-readable medium having a program recorded therein to perform the method according to various embodiments by the processor 235.

[0160] The kernel 251 may control or manage, for example, system resources (e.g., the bus 234, the processor 235, the memory 236, etc.) used to execute an operation or function implemented in other programs (e.g., the API 253, the data logging module 254, the data processing and analysis module 255, etc.). Further, the kernel 251 may provide an interface capable of controlling or managing the system resources by accessing individual constitutional elements of the server 220 in the middleware 252. the API 253, the data logging module 254, and / or the data processing and analysis module 255.

[0161] The middleware 252 may perform, for example, a mediation role so that the API 253, the data logging module 254, and / or the data processing and analysis module 255 may communicate with the kernel 251 to exchange data.

[0162] Further, the middleware 252 may handle one or more task requests received from the API 253, the data logging module 254, and / or the data processing and analysis module 255 according to a priority7. For example, the middleware 252 may assign a priority7of using the system resources (e.g.. the bus 234, the processor 235, or the memory 236) of the server 220 to the data logging module 254, and / or the data processing and analysis module 255. For instance, the middleware 252 may process the one or more task requests according to the priority7assigned to the API 253, the data logging module 254, and / or the data processing and analysis module 255, and thus may perform scheduling or load balancing on the one or more task requests.

[0163] The API 253 may include at least one interface or function (e.g., instruction), for example, for file control, window control, video processing, or character control, as an interface (e.g., the interface module 237, etc.) capable of controlling a function provided by the data loggingmodule 254, and / or the data processing and analysis module 255 in the kernel 251 or the middleware 252. For example, the interface module 237 may play a role of an interface for delivering an instruction or data input from a user or a different external device(s) to the different constitutional elements of the server 220. Further, the interface module 237 may output an instruction or data received from the different constitutional element(s) of the server 220 to the different external device. The interface module 237 may include one or more displays for presenting information to a user, such as information associated with a work session.

[0164] The server 220 may be used to process and / or analyze data / information received from a computing device 117 or a user device 111. The server 220 may process, organize, correlate, validate, update, and / or otherwise manage data / information associated with one or more work sessions. For example, the server 220 may process, organize, correlate, validate, update, and / or otherwise manage image data / information (e.g., raw image data / information and / or raw sensor data / information) received from a computing device 117, such as work session data. For example, the server 220 may execute, perform, and / or facilitate any data / information analysis performed by the computing device 117 (e.g., components of the computing device 117, etc.). The server 220 may process, organize, correlate, validate, update, and / or otherwise manage any data / information associated with the raw image data / information (and / or raw sensor data / information), such as data information received from a user device 111, such as work session data.

[0165] The server 220 may determine and / or confirm location data / information (e.g., GPS coordinates, geospatial data, etc.) associated with one or more work sessions. For example, the work session data may include date and time information that indicates when sensor data was received, as well as GPS coordinates associated with where the sensor data was received. The raw image data / information may be provided to the data logging module 254. The data logging module 254 may be used to generate a log of all events associated with a work session. The data processing and analysis module 255 may be configured to analyze work session data and identify trends that may be used to improve safety, identify crews that are in compliance (or not in compliance) with safety policies, and the like.

[0166] In some embodiments, the data logging module 254 may generate a log of all events associated with a work session. The data logging module 254 may be configured to record and store detailed information about work sessions, safety events, and system operations. In some aspects, the data logging module 254 may include a safety7audit function that systematically examines and documents safety practices, procedures, and incidents during work sessions. This function may collect data on safety protocol adherence, equipment usage, and environmental conditions to provide a comprehensive overview of safety performance.

[0167] The data processing and analysis module 255 may analyze the work session data and identify trends that may be used to improve safety, identify crews that are in compliance (or not in compliance) with safety policies, and the like.

[0168] In some aspects, the data processing and analysis module 255 may include an audit function that systematically reviews and analyzes the data logged by the data logging module 254. This audit function may examine various aspects of work sessions, including safety practices, operational efficiency, and compliance with established protocols. The audit function may generate reports highlighting areas of strength and potential improvement in work processes and safety measures.

[0169] The data processing and analysis module 255 may also incorporate a safety improvement function. This function may analyze trends in safety-related incidents, near-misses, and protocol adherence to identify potential areas for enhancing safety measures. It may generate recommendations for modifying work procedures, updating safety equipment, or providing additional training to personnel based on the analyzed data.

[0170] In some cases, the data processing and analysis module 255 may include a compliance function that assesses adherence to safety policies, regulations, and industry standards. This function may compare logged data against predefined compliance criteria to identify instances of non-compliance. It may generate alerts for immediate action and compile compliance reports for management review.[01711 The module may utilize machine learning algorithms to identify patterns and correlations in the data that may not be immediately apparent through manual analysis. These algorithms may help predict potential safety' risks based on historical data and current work conditions.

[0172] In some implementations, the data processing and analysis module 255 may include a performance evaluation function. This function may analyze data related to work efficiency, task completion times, and resource utilization to provide insights into operational performance. It may generate performance metrics and benchmarks that can be used to optimize work processes and improve overall productivity.

[0173] The module may also feature a data visualization component that presents analyzed data in graphical formats such as charts, graphs, and heat maps. This visual representation of data may facilitate easier interpretation of complex information and trends, supporting more informed decision-making by management.

[0174] Referring to FIGS. 3A-3B, different configurations for mounting platform-based sensors 107 on the work platform 102 (such as for an MEWP 101 or any other elevated mobile or stationary platform, such as a crane, derrick, fixed platform, scaffolding, or stationary' platform)are depicted. In some aspects, as shown in FIG. 3A, the platform-based sensors 107 may be supported by a rail 301 surrounding the work platform 102. The platform-based sensors 107 maybe attached to the rail 301 using hooks 302. This arrangement may be particularly suitable for retrofitting existing work platforms with the platform-based sensors 107. The hooks 302 may provide a flexible and convenient means for attaching the platform-based sensors 107 to the rail 301, allowing for easy installation and removal of the sensors as needed.

[0175] In some aspects, the platform-based sensors 107 may be affixed to the rail 301 or the organizer 303 using various types of mounting mechanisms. For instance, the platform-based sensors 107 may be attached directly to the rail 301 or the organizer 303, or may be mounted on brackets or other supporting structures affixed to the rail 301 or the organizer 303. This flexibilityin mounting options allows for the platform-based sensors 107 to be positioned optimally for detecting objects or users in the zone 108.

[0176] In some embodiments, the platform-based sensors 107 may be integrated with existing structures on the work platform 102. For instance, as depicted in FIGS. 3A-3B, the platformbased sensors 107 may be supported by a rail 301 that surrounds or extends along at least a portion of at least one side of the work platform 102. The rail 301 may serve as a structural element of the work platform 102, providing a convenient and stable mounting surface for the platform-based sensors 107.

[0177] In some cases, the platform-based sensors 107 may be attached to the rail 301 using various types of mounting mechanisms. For example, as shown in FIG. 3A, the platform-based sensors 107 may be attached to the rail 301 using a hook 302 or similar attachment device. This arrangement may allow for easy installation and removal of the platform-based sensors 107, providing flexibility in configuring the system 100.

[0178] In other cases, the platform-based sensors 107 may be directly affixed to the rail 301, such as by welding, bolting, or using adhesive. This may provide a more permanent and secure attachment of the platform-based sensors 107 to the rail 301.

[0179] In some aspects, the positioning of the platform-based sensors 107 on the rail 301 maybe adjustable. This may allow for the platform-based sensors 107 to be repositioned as needed to adapt to changes in the work environment or the nature of the work being performed. For example, the platform-based sensors 107 may be moved to different locations along the rail 301 to optimize the coverage of the zone 108.

[0180] In some embodiments, the platform-based sensors 107 may be integrated with the rail 301 at the time of manufacture of the work platform 102. This may provide a seamless integration of the platform-based sensors 107 with the work platform 102, enhancing the aesthetic and functional design of the work platform 102.

[0181] In some cases, the rail 301 may include features designed to facilitate the integration of the platform-based sensors 107. For example, the rail 301 may include mounting brackets, slots, or other features designed to receive and secure the platform-based sensors 107.

[0182] In some aspects, the platform-based sensors 107 may be affixed to the rail 301 using various alternative attachment mechanisms. For example, the sensors may be secured using adjustable clamps that can grip the rail 301 at different positions. These clamps may feature a tightening mechanism, such as a screw or lever, allowing for quick installation and removal while providing a secure hold.

[0183] In some cases, magnetic mounts may be employed to attach the platform-based sensors 107 to the rail 301. These magnetic mounts may incorporate strong neodymium magnets that provide a robust connection to metal rails while allowing for easy repositioning of the sensors as needed.

[0184] The platform-based sensors 107 may also be affixed using bracket systems that can be bolted or welded to the rail 301. These brackets may offer a more permanent mounting solution while still allowing for sensor removal or replacement. In some implementations, the brackets may feature quick-release mechanisms for efficient sensor detachment.

[0185] In some aspects, strap or band-based attachments may be utilized to secure the platform-based sensors 107 to the rail 301. These straps may be made of durable materials such as reinforced nylon or metal and may incorporate tensioning systems for a snug fit around rails of varying dimensions.

[0186] The platform-based sensors 107 may also be mounted using custom-designed rail adapters that slide or clip onto the rail 301. These adapters may be tailored to fit specific rail profiles and may include integrated sensor mounts or attachment points.

[0187] In some cases, suction cup mounts may be employed for attaching the platform-based sensors 107 to smooth surfaces of the rail 301 or work platform 102. These suction cups may incorporate vacuum pump mechanisms to ensure a secure hold while allowing for easy removal and repositioning.

[0188] In some aspects, the platform-based sensors 107 may need to be positioned at various angles to create a suitable zone 108 around the work platform 102. The sensors may be oriented downward at angles ranging from 0 to 90 degrees relative to the horizontal plane of the work platform 102. This downward orientation may allow' for detection of objects or personnel directly beneath the work platform 102.

[0189] In some cases, the platform-based sensors 107 may be angled outward from the edges of the work platform 102. These outw ard-facing sensors may be positioned at angles between 0 and 180 degrees relative to the vertical plane of the work platform's edge. This configuration mayenable detection of objects or personnel approaching the work platform 102 from various directions.

[0190] The platform-based sensors 107 may also be arranged in a multi-tiered configuration, with some sensors angled downw ard and others angled outward. This arrangement may provide comprehensive coverage of both the area directly beneath the work platform 102 and the surrounding perimeter.

[0191] In some implementations, the platform-based sensors 107 may incorporate adjustable mounting mechanisms that allow for fine-tuning of sensor angles. These adjustable mounts may enable operators to optimize the detection zone based on specific work environments or safety requirements.

[0192] The system 100 may include sensors with wide-angle lenses or rotating mechanisms that can scan across a range of angles. These sensors may provide dynamic coverage of the zone 108, adapting to changes in the work platform's height or position.

[0193] In some aspects, the positioning of the platform-based sensors 107 may be automatically adjusted based on the height and orientation of the work platform 102. This adaptive positioning may ensure that the zone 108 is consistently maintained regardless of the work platform's movement or elevation.

[0194] In some cases, as shown in FIG. 3B, the platform-based sensors 107 may be affixed to an organizer 303 surrounding the work platform 102. The organizer 303 may be a structure that is integrated with or otherwise attached to the work platform 102, providing a mounting surface for the platform-based sensors 107. The organizer 303 may be configured to permit organization of tools, parts, equipment, and the like, in addition to supporting the platform-based sensors 107. This configuration may be suitable for new work platform designs or more permanent sensor installations.

[0195] In some embodiments, the platform-based sensors 107 may be positioned at various locations on the rail 301 or the organizer 303 to optimize the coverage of the zone 108. The positioning of the platform-based sensors 107 may be adjustable, allowing for the sensors to be repositioned as needed to adapt to changes in the work environment or the nature of the work being performed.

[0196] Referring to FIG. 4, a flow chart illustrating a method 400 for enhancing safety around a work platform using sensor-based technology7is depicted. The method may include several steps designed to detect and alert users when they enter a predefined hazardous zone around the work platform. The method 400 may be used in conjunction with the MEWP 101 of FIGs. 1A-F. While the example of FIG. 4 may be used in conjunction with the MEWP 101, this is for example purposes only, as the methods and system described with reference to FIG. 4 is contemplated tobe used with and applicable to other elevated mobile or stationary platforms, including, but not limited to, cranes, derricks, fixed platforms, scaffolding, and stationary elevated platforms. As such, the features, operations and capabilities described with reference to the MEWP 101 in FIG. 4 may also be applicable to these other elevated mobile or stationary platforms.

[0197] In some aspects, the method may begin with emitting a signal from platform-based sensors mounted on the work platform at 402. These sensors may be configured to define a safetyzone around the platform. The signal emitted by the platform-based sensors may utilize various technologies such as radio frequency, infrared, or ultrasonic waves.

[0198] The method may then proceed to a detection step, where user-based sensors affixed to individuals working near the platform detect the emitted signal at 404. These user-based sensors may be incorporated into personal protective equipment such as hard hats, safety vests, or wearable devices. The detection of the signal by the user-based sensors may indicate that the user has entered the predefined safety zone.

[0199] Following the detection, the method may include triggering an alarm on the user-based sensor at 406. This alarm may serve to alert the user that they have entered the hazardous zone, prompting them to take necessary safety- measures or vacate the area. The alarm may be audible, visual, tactile, or a combination thereof, depending on the specific implementation and work environment requirements.

[0200] In some implementations, the method may incorporate a feedback loop where the user-based sensors communicate their status back to a central monitoring system. This may allow for real-time tracking of personnel locations relative to the safety zone and enable more comprehensive safety7management.

[0201] The method may also include steps for dynamically adjusting the safety zone based on the movement or repositioning of the work platform. This may involve continuous recalibration of the platform-based sensors to ensure accurate definition of the safety7zone as the work environment changes.

[0202] In some cases, the method may incorporate additional steps for logging and analyzing safety- data. This may include recording instances of zone breaches, duration of time spent in the safety zone, and patterns of user behavior. Such data may be used to inform safety protocols, identify areas for improvement, and enhance overall workplace safety practices.

[0203] Referring to FIG. 5, a perspective view of a safety- system for a mobile elevating work platform (MEWP) 101 is illustrated. While the example of FIG. 5 may show the MEWP 101, this is for example purposes only, as the methods and system described with reference to FIG. 5 are contemplated to be used with and applicable to other elevated mobile or stationary platforms, including, but not limited to, cranes, derricks, fixed platforms, scaffolding, and stationary elevatedplatforms. As such, the features, operations and capabilities described with reference to the MEWP 101 in FIG. 5 may also be applicable to these other elevated mobile or stationary’ platforms. The MEWP 101 may include a vehicle base with wheels and an articulated arm supporting a work platform 102 at its upper end. The work platform 102 may be shown in an elevated position, with platform-based sensors 107 mounted on its exterior.

[0204] In some aspects, a ground user 106 may be depicted standing near the MEWP 101. The ground user 106 may be wearing a hard hat 110 equipped with a user-based sensor 109. Additionally, the ground user 106 may be holding a user device 111 in hand. These elements may be positioned within a zone 108, which may be indicated by lines extending from the work platform 102 to the ground.

[0205] The arrangement of the platform-based sensors 107 on the work platform 102 and the user-based sensor 109 on the hard hat 110 may demonstrate the system's capability to monitor the zone 108 around the MEWP 101. The presence of the user device 111 may suggest an additional means of communication or sensing within the safety system.

[0206] In some cases, the perspective view may provide a clear representation of the spatial relationships between the MEWP 101. the work platform 102. the ground user 106, and the various sensors (107, 109) that may comprise the safety system. The illustration may effectively convey the integration of these components in a typical work environment where elevated platforms are utilized.

[0207] In some aspects, the user-based sensor 109 affixed to the hard hat 110 of the ground user 106 may detect that it has breached the zone 108 created by the platform-based sensors 107. This detection may occur when the ground user 106 enters the area defined by the dashed lines extending from the work platform 102 to the ground. Upon detecting the breach, the system may generate an alert to notify the ground user 106 of their presence in a potentially hazardous area.

[0208] The alert may be generated and delivered through various means. In some cases, the user-based sensor 109 itself may produce an audible, visual, or tactile alert to immediately notify the ground user 106. For example, the sensor may emit a beeping sound, flash a warning light, or vibrate to draw the user's attention.

[0209] In other implementations, the alert may be transmitted to and displayed on the user device 111 held by the ground user 106. The user device 111 may receive a wireless signal from either the user-based sensor 109 or the platform-based sensors 107, triggering a notification on its screen or through its speakers.

[0210] The platform-based sensors 107 may also play a role in generating the alert. Upon detecting the presence of the user-based sensor 109 within the zone 108, these sensors mayactivate warning lights or sirens on the work platform 102 or the MEWP 101, providing a visual or audible alert to both the ground user 106 and any personnel on the elevated platform.

[0211] In some cases, the alert may be relayed to a central monitoring system or control station, which may then communicate the warning to the ground user 106 through a separate communication channel, such as a two-way radio or a smartphone app.

[0212] The system may also incorporate other devices not pictured in Figure 5 to deliver alerts. For instance, wearable devices such as smart watches or safety glasses with heads-up displays may be used to provide immediate, personalized alerts to the ground user 106 upon zone breach detection.

[0213] A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other implementations are within the scope of the following claims.
