Modular personal protective equipment (PPE), comprising interconnected wearable monitoring and communications components integrated in personal safety equipment including helmet, glasses and vest. T

Description

[0002] The current state of communication and monitoring solutions in hazardous or regulated work environments often faces significant challenges. Traditionally, such environments have relied heavily on handheld communication devices like mobile phones or radios, which pose multiple drawbacks. These devices require workers to actively engage their hands to operate, limiting their ability to focus on tasks, which may increase risks in safety-critical situations. Furthermore, handheld devices are prone to damage or loss in fast-paced or rough conditions, and their reliance on manual operation introduces inefficiencies in environments where speed and precision are vital.

[0003] In recent years, the integration of wearable technologies into professional settings has emerged as a potential solution to these challenges. However, the existing options for wearable communication and monitoring devices remain fragmented and insufficiently integrated. Helmets with built-in communication and recording functionalities have been introduced in some industries, but their utility is often limited to supervisors or specific tasks, failing to provide a comprehensive solution for diverse roles within the workforce. These systems frequently lack modularity, rendering them unsuitable for use across a range of industries, such as security, manufacturing, and construction, which require flexible and adaptable solutions.

[0004] Another limitation of current wearable technologies lies in their inability to ensure consistent and seamless long-distance communication. Most wearable devices rely on Bluetooth or similar short-range protocols, which are insufficient for large construction sites or industrial facilities where workers may be spread over vast areas. This limitation forces a continued dependence on traditional communication devices, undermining the benefits of wearable systems. Additionally, these technologies are often not designed to comply with evolving safety regulations, such as bans on earbuds or external music players in certain hazardous environments, leaving a gap in the market for compliant solutions.

[0005] Recording capabilities integrated into existing wearable systems often prioritize niche applications, such as site mapping or specific repair tasks, without addressing broader use cases like incident documentation, task monitoring, or security operations. These functionalities are typically constrained by poor video quality, limited recording durations, and cumbersome user interfaces. In scenarios requiring hands-free operation, such as security personnel managing crowds or electricians working in confined spaces, the lack of intuitive controls and robust functionality presents significant barriers to effective use.

[0006] Power supply is another critical issue faced by current wearable systems. Most existing devices are designed with proprietary power solutions that are not interoperable across different components. This not only adds to the cost and complexity of these systems but also reduces their practicality for end users who need devices capable of prolonged operation without frequent recharging. Furthermore, existing devices rarely provide power-sharing capabilities, such as charging third-party devices, which could significantly enhance utility in professional settings.

[0007] Despite the emergence of various smart glasses and augmented reality systems, their adoption in professional environments has been limited by factors such as bulkiness, lack of water resistance, and reliance on smartphone connectivity. These limitations, combined with suboptimal integration of communication, recording, and environmental adaptability, make such systems less effective for industries requiring robust, standalone solutions. As a result, there remains a need for wearable systems that can seamlessly integrate communication, recording, and safety monitoring while being flexible enough to meet the needs of diverse industries and compliant with safety regulations.

[0008] These factors collectively underscore the inadequacies in existing wearable systems for communication and monitoring in hazardous or regulated environments. The need for a multi-component ecosystem that addresses these limitations, offering a modular, integrated, and compliant solution, is increasingly evident.

[0009] It is within this context that the present invention is provided. Summary

DESCRIPTION OF DRAWINGS

[0065] The present invention relates to a modular personal protective equipment (PPE) system designed to enhance communication, monitoring, and safety for workers in professional environments. The system integrates multiple wearable components— specifically a safety helmet, a vest, and smart glasses—into a cohesive network, enabling seamless communication and coordination among users across various workplace settings. Each component is capable of performing independently or as part of an interconnected system, providing flexibility and adaptability to different operational requirements.

[0066] Traditional PPE systems often focus solely on physical protection, neglecting the importance of effective communication and situational awareness in hazardous environments. Existing solutions for wearable technology in workplaces may lack modularity, limiting their ability to adapt to diverse tasks or industries. Furthermore, prior art addressing communication among workers often suffers from issues such as interference, limited range, and difficulty managing multiple users in complex environments. These shortcomings can lead to inefficiencies, miscommunication, and increased safety risks.

[0067] The invention overcomes these limitations by providing a modular system in which each component is designed to integrate seamlessly into a secure, low-latency network. The system's hybrid communication protocol combines long-range radio frequency (RF) communication with short-range Bluetooth Low Energy (BLE) technology, ensuring reliable connectivity across large worksites while maintaining device coordination within close proximity. The inclusion of features such as adaptive frequency-hopping and unique device identifiers prevents interference and enables clear communication even in crowded or signal-dense environments.

[0068] The modular nature of the system allows components to be configured for specific tasks or industries without unnecessary complexity. For instance, the safety helmet serves as a central communication hub, managing data from the vest's activity sensors and the smart glasses' visual input device. This integration improves situational awareness, enhances productivity, and allows for real-time monitoring of worker activity and safety conditions. Additionally, the system's ability to operate as standalone components or as part of a broader ecosystem ensures compatibility with various workflows and operational scales.

[0069] Referring now to the drawings, FIGS. 1A-1E detail the structural and functional elements of the smart glasses 100, showcasing their integration of advanced technologies for communication, data capture, and augmented reality.

The camera 104 supports both real-time data transmission and local storage, ensuring functionality in environments with limited connectivity. The system tags recorded media with metadata such as time, location, and task identifiers when integrated with other PPE components like the safety helmet. This metadata facilitates efficient organization and retrieval of captured data for review or compliance purposes.

[0072] The smart glasses 100 incorporate a directional audio system, including bone conduction speakers 106 embedded in the temples and a noise-canceling microphone array 108. The speakers 106 provide clear audio output directly to the user, minimizing external disturbances and ensuring privacy in communication. This configuration is particularly advantageous in noisy workplaces, where traditional audio systems may struggle to deliver intelligible sound. The microphone array 108 ensures accurate audio input by suppressing background noise, enabling reliable voice communication and hands-free operation. Workers can issue voice commands such as "Record video," "Capture photo," or "Send status update" while keeping their hands free for tasks.

[0073] Embedded within the frame is a slim, rechargeable power cell designed to support extended operation of the glasses 100. This power source enables the glasses to function independently or in conjunction with other components of the PPE system, such as the safety helmet or vest. The power cell is compatible with USB-C charging and can draw supplementary power from other system components when necessary. This modular powersharing capability ensures continuous operation during prolonged tasks or in the event of battery depletion.

[0074] The glasses 100 are powered by the Qualcomm ARI Gen 1 platform, which provides robust on-device processing capabilities. This platform supports advanced features such as real-time video recording, augmented reality overlays, and Al-based command execution. By processing tasks locally, the glasses achieve low latency and reliable performance, even in environments where external network connectivity is unavailable. Augmented reality overlays projected onto the lenses 102 provide workers with task-related instructions, safety alerts, or other contextual information within their field of view, enhancing efficiency and situational awareness.

[0075] The arms 110 and 112 of the glasses feature removable covers which allow for easy maintenance or component upgrades. The arms house wiring and connectors for interfacing with the embedded electronics while maintaining a compact and streamlined form factor. This modularity enables the glasses to adapt to specific user needs, including compatibility with future technological advancements.

[0076] In FIG. IB, a perspective view of the glasses 100. FIG. IC presents a side view. FIG. ID shows a top view of the glasses 100. FIG. IE illustrates a front view.

[0077] When used as part of the broader PPE system, the glasses 100 integrate seamlessly with the safety helmet and vest through a secure, low-latency mesh network. This network employs hybrid communication protocols, including radio frequency (RF) for long-range data transmission and Bluetooth Low Energy (BLE) for short-range device coordination. The safety helmet serves as the master node, managing data synchronization and communication resource allocation for all connected devices.
