DETAILED DESCRIPTION

[0047]Referring generally to the figures, various embodiments of a hard hat communication system are provided. In contrast to typical communication systems that are used on job or constructions sites where the devices may be shared, the charger and/or docking station is configured to modify the settings of the individual communication devices to allow for easier pairing to individual users or groups of users. In various specific embodiments, communicators charged in a charging station are automatically configured to communicate to each other. In such embodiments, communicators charged in different charging stations are automatically configured to not communicate to each other. Applicant believes the automatic device set up improves efficiency on a work site where multiple communication devices are frequently in use and shared. Instead of group coordination or requiring set up of the communication devices every day, the communication devices are paired and ready for use when removed from the charging station.

[0048]In various embodiments, the communication system includes a near-field communication (NFC) tag to allow for storing personalized user data for shared the communication devices. Applicant believes for shared worksite communication devices, storage of personalized data with the user rather than the shared device improves efficiency and reduces confusion for works who will not be required to reset the communication devices to their personal preferences on a daily basis. In a specific embodiment, the user's personal data is stored on an NFC tag coupled to a hard hat. When the communicator is placed near the tag the personalized data can be read by the communicator. In various other embodiments, a component including storage (e.g., memory) and a communications interface is permanently coupled to the user's hard hat. In such embodiments, when the communicator or shared device is connected to the component coupled to the hard hat, personalized information is read from the storage.

[0049]Furthermore, Applicant believes mounting and/or integrating the communication system with the hard hat, the shell, the suspension, the chin strap, etc. improves safety and efficiency by allowing for hands free communication. For example, the ability to take phone calls, communicate with other workers, listen to entertainment (e.g., radio, podcasts, music, etc.) without requiring use of hands or the distraction of another device (e.g., phone) improves communication without jeopardizing the situational awareness of the worker. Additionally, Applicant believes the integration into personal protective equipment such as a hard hat provides a light weight communication solution that does not interfere with other critical equipment such as tool belts. Finally, Applicant believes the integration of communication systems within the hard hat or hard hat components provides better proximity to the ears and mouth of a user improving the quality of communication.

[0050]In various embodiments, the communication system allows for connecting and disconnecting the communication system or device (e.g., with a magnet or simple audio jack/connector) at different times (i.e., hard hat followed by headset or headset followed by hard hat) reducing the likelihood of the device becoming entangled and allowing for quick and easy removal of any tangles in the communication system components. In various embodiments, the communication system or device is designed to be symmetrical. Applicant believes the symmetry allows individual users freedom to mount the communication system based on personal preference and allow for control with either the left or right hand.

[0051]In various embodiments, the communication system includes an adjustable band sizing for increased comfort and fit of the wearer and a proper fit (e.g., tight) to reduce the likelihood of snagging the system components on the work site.

[0052]In various embodiments, the communication system uses bone conduction technology. Applicant believes the use of bone conduction allows for supplementing of standard air conduction audio delivery that may be hampered by the use of hearing protection (earmuffs, ear plugs, etc.). In various specific embodiments, the bone conduction transducers are integrated into the hard hat and/or liner. Applicant believes integration into the hard hat or liner allows workers to use hearing protection without impacting their ability to communicate.

[0053]In various specific embodiments, the bone conduction transducers are integrated into an earmuff. Applicant believes integration into earmuffs allows for a worker to wear both earplugs and earmuffs simultaneously in extremely loud environments while maintaining the ability to hear communications. Additionally, Applicant believes that because earmuffs are light weight and comfortable, workers are more likely to wear hearing protection over a longer period of time (e.g., the entire work day). Finally, Applicant believes the integration of the bone conduction transducer in the earmuff cushion allows for the earmuff to maintain the proper sealing to a user's skin for the necessary noise reduction rating (NRR).

[0054]Referring to FIGS. 1-3, a communication system 10 including a charging system 11 is shown according to an exemplary embodiment. Communication system 10 includes a headset 12 and a communicator 14. In various specific embodiments, headset 12 communicates 16 to a communicator device or communicator 14 wirelessly (e.g., Wi-fi, RF, Bluetooth, etc.). In specific embodiments, headset 12 is paired with communicator 14 using Bluetooth.

[0055]As will be generally understood, on work or job sites, numerous workers have their own communicator device. A first communicator 14 communicates to a second communicator 18 wirelessly. In various specific embodiments, the first communicator 14 and second communicator 18 are configured to be in the same talking group or channel 20. For example, in a specific embodiment, communicator 14 and communicator 18 are part of a mesh network.

[0056]Referring to FIG. 3, details of charging system 11 are shown according to an exemplary embodiment. In various specific embodiments, a first charger or base station 22 is configured to receive and charge headset 12 and communicator 14. In various embodiments, charging system includes a second charger or base station 24 configured to receive and charge headset 12 and communicators 14, 18.

[0057]Each charger 22, 24 includes one or more bays 26 sized to receive a headset 12 and a communicator 14. A headset 12 charged in the same bay 26 as a communicator 14 will only work or communicate with each other and not need to be paired with another communication device. In other words, if a headset 12 previously paired with a communicator 14 is placed in a bay 26 with another communicator 14, the original communicator 14 is forgotten. All of the communicators 14 charged within first charger 22 automatically have their settings updated to communicate with the other communicators 14 charged within first charger 22. In contrast, because communicator 18 is charged in second charger 24, communicator 18 is automatically configured (e.g., programmed) to not communicate with communicator 14 that has been charged in a different charger (e.g., first charger 22).

[0058]Each charger 22, 24 includes an interface 28, shown schematically, to allow a user to change device settings. Each bay 26 includes an indicator, shown as status light 30. In various specific embodiments, status light 30 is used to indicate whether a headset 12 has been paired with a communicator 14, 18. When a headset 12 is paired with a communicator 14, 18 the status light 30 is green and when the headset 12 is not paired with a communicator 14, 18 the status light 30 is red.
