[0100] As diagrammed in
[0101] In operation, mask (10) allows users to choose the level and extent of functionality based on individual preference or workplace requirements. For instance, individuals may prefer, or workplace conditions may require, use of half-mask face protector (100) in conjunction with either basic communications module (300), intermediate communications module (500), or advanced communications module (700). Alternatively, individuals may prefer, or workplace conditions may require, use of full-mask face protector (200) in conjunction with either basic communications module (300), intermediate communications module (500), or advanced communications module (700). Communications module mount (114) of half-mask face protector (100) and communications module mount (216) of full-mask face protector (200) are fabricated to mount securely either of the three inventive communications modules according to the present invention. Thus, basic communications module (300), intermediate communications module (500) or advanced communications module (700) may be used in conjunction with half-mask face protector (100) or full-mask face protector (200), depending on individual preference or workplace requirements.
[0102] Each of the inventive communications modules comprise a replaceable selection panel, which houses multiple functional components that a user may access during use of mask (10). Because users are likely to contact the replaceable selection panel frequently during use of mask (10) (i.e., to activate power, control volume, adjust squelch sensitivity or activate a speaker, etc.), the replaceable selection panel may become soiled or damaged in harsh conditions. The ability to replace a damaged selection panel with a new replaceable selection panel obviates the need to purchase an entirely new mask (10) unit if the initial selection panel falls into disrepair, which extends the functional life of mask (10) and provides cost savings to mask (10) users.
[0103] Individuals who are not wearing mask (10) may wish to communicate with other individuals who are wearing mask (10). In such a scenario, handheld communications module (900) may be used by individuals who are not wearing mask (10) in order to communicate with mask (10) users.
Basic Communications Module (300)
[0104] Basic communications module (300) allows an operator to use interior microphone (110) and exterior speaker(s) (112) of half-mask face protector (100), or interior microphone (212) and exterior speaker(s) (214) of full-mask face protector (200), to facilitate short distance communications. In operation, basic communications module (300) is mounted to either half-mask face protector (100) via communications module mount (114), or mounted to full-mask face protector (200) via communications module mount (216).
[0105] During use of mask (10), a plurality of indicator light-emitting diode devices (402), which are positioned on replaceable basic selection panel (400), indicate the status of basic communications module (300) functionality. More specifically, light-emitting diode devices (402) indicate basic communications module (300) status by displaying different colors, each color corresponding to the functional state of basic communications module (300). For instance, plurality of light-emitting diode devices (402) function as follows to display status indicator colors: glow blue when basic communications module (300) power is on; slowly blink blue when basic communications module (300) is in use; rapidly blink blue when basic communications module (300) is in wireless handshaking mode; blink red when basic communications module (300) is charging; glow red when basic communications module (300) is fully charged but the power charger is still attached; and blink alternating red and blue when basic communications module (300) encounters an error (i.e., if half-mask face protector (100) or full-mask face protector (200) is not properly connected to basic communications module (300), etc.). Light-emitting diode devices (402) glow is off when basic communications module (300) power is off.
[0106] During use of mask (10), an operator can adjust various functions of basic communications module (300) by accessing jog dial (408) on replaceable basic selection panel (400). Jog dial (408) is fabricated to combine jog and push button activation to adjust various functional options through replaceable basic selection panel (400). For instance: holding jog dial (408) inward for approximately 3 seconds turns basic communications module (300) on or off; pressing jog dial (408) once rapidly alternates jog dial (408) control between volume level mode and squelch sensitivity level mode; turning jog dial (408) when in squelch sensitivity level mode increases or decreases squelch sensitivity (i.e., microphone cut-off sensitivity levels); and pressing jog dial (408) twice in rapid succession broadcasts the power supply (i.e., battery) level from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. The default state of jog dial (408) is set to adjust speaker volume levels, so that turning jog dial (408) when in default mode increases or decreases speaker volume levels.
[0107] During use of mask (10), an operator can control mask (10) microphones and speakers by pressing speaker button (410) on replaceable basic selection panel (400). For instance, pressing speaker button (410) on replaceable basic selection panel (400) turns on or off exterior speaker(s) 112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. In this mode, interior microphone (110) of half-face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the corresponding signal goes through audio processor (320) of control unit (318) to squelch and clarify an operator's muffled or otherwise distorted voice, and to broadcast the operator's clarified voice from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use.
[0108] Basic communications module (300) may be connected to a conventional USB power source to charge a power supply (322) battery, or may be connected to a computer to charge a power supply (322) battery or upload firmware updates to control unit (318) and corresponding audio processor (320). For instance, upgraded control unit (318) firmware may comprise upgraded programming to facilitate bug fixes and additional functionality. Upgraded audio processor (320) firmware may comprise upgraded programming for bug fixes to squelch, background noise filtering, and clarification of an operator's muffled or otherwise distorted voice.
Intermediate Communications Module (500)
[0109] Intermediate communications module (500) allows an operator to use interior microphone (110) and external speaker(s) (112) of half-mask face protector (100), or interior microphone (212) and exterior speaker(s) (214) of full-mask face protector (200), to facilitate short distance communications, as well as intercom communications at a longer distance between other users of intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900). Such communications may occur between operators in separate rooms or separate floors of a location, and under similar conditions where operators are out of the line-of-site of other operators. In operation, intermediate communications module (500) is mounted to either half-mask face protector (100) using communications module mount (114), or mounted to full-mask face protector (200) using communications module mount (216).
[0110] During use of mask (10), a plurality of indicator light-emitting diode devices (602), which are positioned on replaceable intermediate selection panel (600), indicate the status of intermediate communications module (500) functionality. More specifically, light-emitting diode devices (602) indicate intermediate communications module (500) status by displaying different colors, each color corresponding to the functional state of intermediate communications module (500). For instance, plurality of light-emitting diode devices (602) function as follows to display status indicator colors: glow blue when intermediate communications module (600) power is on; slowly blink blue when intermediate communications module (500) is in use; rapidly blink blue when intermediate communications module (500) is in wireless handshaking mode; blink red when intermediate communications module (500) is charging; glow red when intermediate communications module (500) is fully charged but the power charger is still attached; and blink alternating red and blue when intermediate communications module (500) encounters an error (i.e., if half-mask face protector (100) or full-mask face protector (200) is not properly connected to intermediate communications module (500), etc.). Light-emitting diode devices (602) glow is off when intermediate communications module (500) power is off.
[0111] During use of mask (10), an operator can adjust various functions of intermediate communications module (500) by accessing jog dial (610) on replaceable intermediate selection panel (600). Jog dial (610) is fabricated to combine jog and push button activation to adjust various functional options through replaceable intermediate selection panel (600). For instance: holding jog dial (610) inward for approximately 3 seconds turns intermediate communications module (500) on or off; pressing jog dial (610) once rapidly alternates jog dial (610) control between volume level mode and squelch sensitivity level mode; turning jog dial (610) when in squelch sensitivity level mode increases or decreases squelch sensitivity (i.e., microphone cut-off sensitivity levels); and pressing jog dial (610) twice in rapid succession broadcasts the power supply (i.e., battery) level from exterior speaker(s) (112) of half-mask face protector (100) or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. The default state of jog dial (610) is set to adjust speaker volume levels, so that turning jog dial (610) while in default mode increases or decreases speaker volume levels.
[0112] During use of mask (10), an operator can control mask (10) microphones and speakers by pressing speaker button (612) on replaceable intermediate selection panel (600). For instance, pressing speaker button (612) on replaceable intermediate selection panel (600) turns on or off exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. In this mode, interior microphone (110) of half-face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the corresponding signal goes through audio processor (526) of control unit (524) to squelch and clarify an operator's muffled or otherwise distorted voice, and to broadcast the operator's clarified voice from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use.
[0113] Intermediate communications module (500) is fabricated to operate using intercom wireless network communications. For a secure intercom wireless network unestablished intermediate communications module (500), holding intercom button (614) on replaceable intermediate selection panel (600) for approximately 3 seconds activates wireless handshaking to establish a secure connection with another unestablished intermediate communications module (500), advanced communications module (700) or handheld communications module (900), which is also in handshaking mode. Two unestablished intermediate communications modules (500), advanced communications modules (700) or handheld communications modules (900), will agree on a security code to establish their own secure intercom wireless network connection. One established intermediate communications module (500), advanced communications module (700), or handheld communications module (900), will connect with an unestablished intermediate communications module (500), advanced communications module (700), or handheld communications module (900), to inform it of the established secure intercom wireless network connection's security code. In this way, two established intermediate communications modules (500), advanced communications modules (700), or handheld communications modules (900), can expand the secure intercom wireless network to include additional intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900).
[0114] For a secure intercom wireless network established intermediate communications module (500), pressing (once quickly) an established intermediate communications module's intercom button (614), located on replaceable intermediate selection panel (600), sends a call out to all intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), in range that are using a similar security code to connect with as part of the secure intercom wireless network. Pressing intercom button (614) again (once quickly) will disconnect that one intermediate communications module (500), advanced communications module (700) or handheld communications module (900), from the currently connected secure intercom wireless network. Depending on which face protector is selected for use, interior microphone (110) of half-mask face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the signal goes through audio processor (526) to squelch and clarify an operator's muffled or otherwise distorted voice, and to broadcast the operator's clarified voice to the other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network.
[0115] If headphones are not connected to headphone jack (518) of intermediate communications module main body (502), transmissions from other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the same secure intercom wireless network, are broadcast from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. Alternatively, if headphones are connected to headphone jack (718) of advanced communications module main body (702), transmissions from other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network, are broadcast from corresponding headphones connected to headphone jacks (518), (718) or (916), respectively, depending on which communications modules are in use.
[0116] Holding (for approximately 6 seconds) intercom button (614) of replaceable intermediate selection panel (600) deletes the secure intercom wireless network security code from memory unit (532) of intermediate communications module (500), so that intermediate communications module (500) is free to connect with a new secure intercom wireless network.
[0117] Intermediate communications module (500) may be connected to a conventional USB power source to charge a power supply (530) battery, or may be connected to a computer to charge a power supply (530) battery, or upload firmware updates to control unit (524) and corresponding audio processor (526). For instance, upgraded control unit (524) firmware may comprise upgraded programming to facilitate bug fixes and additional functionality. Upgraded audio processor (526) firmware may comprise upgraded programming for bug fixes to squelch, background noise filtering, and clarification of an operator's muffled or otherwise distorted voice.

[0118] Advanced communications module (700) allows an operator to use interior microphone (110) and external speaker(s) (112) of half-mask face protector (100), or interior microphone (212) and exterior speaker(s) (214) of full-mask face protector (200), to facilitate short distance communications, and a wireless transmitter/receiver as an intercom to facilitate communications at a longer distance between other users of intermediate communications module (500), advanced communications module (700), or handheld communications module (900) (such as between users who are in separate rooms, on different floors, or otherwise out of the line-of-sight of other operators in a location). Advanced communications module (700) also provides operators the ability to connect (either with wireless media connection module (733) connection or direct 3.5 mm conventional auxiliary wire) with media devices (724), allowing operators to listen to music, access information, place and receive phone calls, and otherwise utilize the functional capabilities of media device (724) during use of mask (10). In operation, advanced communications module (700) is mounted to either half-mask face protector (100) using communications module mount (114), or mounted to full-mask face protector (200) using communications module mount (216).
[0119] During use of mask (10), a plurality of indicator light-emitting diode devices (802), which are positioned on replaceable advanced selection panel (800), indicate the status of advanced communications module (700) functionality. More specifically, light-emitting diode devices (802) indicate advanced communications module (700) status by displaying different colors, each color corresponding to the functional state of advanced communications module (700). For instance, plurality of light-emitting diode devices (802) function as follows to display status indicator colors: glow blue when advanced communications module (700) power is on; slowly blink blue when advanced communications module (700) is in use; rapidly blink blue when advanced communications module (700) is in wireless handshaking mode; blink red when advanced communications module (700) is charging; glow red when advanced communications module (700) is fully charged but the power charger is still attached; and blink alternating red and blue when advanced communications module (700) encounters an error (i.e., if half-mask face protector (100) or full-mask face protector (200) is not properly connected to advanced communications module (700), etc.). Light-emitting diode devices (802) glow is off when advanced communications module (700) power is off.
[0120] During use of mask (10), an operator can adjust various functions of advanced communications module (700) by accessing jog dial (808) on replaceable advanced selection panel (800). Jog dial (808) is fabricated to combine jog and push button activation to adjust various functional options through replaceable advanced selection panel (800). For instance: holding jog dial (808) inward for approximately 3 seconds turns advanced communications module (700) on or off; pressing jog dial (808) once rapidly alternates jog dial (808) control between volume level mode and squelch sensitivity level mode; turning jog dial (808) when in squelch sensitivity level mode increases or decreases squelch sensitivity (i.e., microphone cut-off sensitivity levels); and pressing jog dial (808) twice in rapid succession broadcasts the power supply (i.e., battery) level from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. The default state of jog dial (808) is set to adjust speaker volume levels, so that turning jog dial (808) while in default mode increases or decreases speaker volume levels.
[0121] During use of mask (10), an operator can control mask (10) microphones and speakers by pressing speaker button (810) on replaceable advanced selection panel (800). For instance, pressing speaker button (810) on replaceable advanced selection panel (800) turns on or off exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. In this mode, interior microphone (110) of half-face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the corresponding signal goes through audio processor (730) of control unit (728) to squelch and clarify an operator's muffled or otherwise distorted voice, and to broadcast the operator's clarified voice from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use.
[0122] Advanced communications module (700) is also fabricated to operate using intercom wireless network communications. For a secure intercom wireless network unestablished advanced communications module (700), holding intercom button (812) on replaceable advanced selection panel (800) for approximately 3 seconds activates wireless handshaking to establish a secure connection with another unestablished intermediate communications module (500), advanced communications module (700), or handheld communications module (900), which are also in handshaking mode. Two unestablished intermediate communications modules (500), advanced communications modules (700), or handheld communications modules (900) will agree on a security code to establish their own secure intercom wireless network connection. One established intermediate communications module (500), advanced communications module (700), or handheld communications module (900), will connect with an unestablished intermediate communications module (500), advanced communications module (700), or handheld communications module (900), to inform it of the established secure intercom wireless network connection's security code. In this way, two established intermediate communications modules (500), advanced communications modules (700), or handheld communications modules (900), can expand the secure intercom wireless network to include additional intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900).
[0123] For a secure intercom wireless network established advanced communications module (700), pressing (once quickly) an established advanced communications module's intercom button (812), located on replaceable advanced selection panel (800), sends a call out to all intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), in range that are using a similar security code to connect with as part of the secure intercom wireless network. Pressing intercom button (812) again (once quickly) will disconnect that one intermediate communications module (500), advanced communications module (700), or handheld communications module (900), from the currently connected secure intercom wireless network. Depending on which face protector is selected for use, interior microphone (110) of half-mask face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the signal goes through audio processor (730) to squelch and clarify an operator's muffled or otherwise distorted voice, and to broadcast the operator's clarified voice to other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network.
[0124] If headphones are not connected to headphone jack (718) of advanced communications module main body (702), transmissions from other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the same secure intercom wireless network, are broadcast from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. Alternatively, if headphones are connected to headphone jack (718) of advanced communications module main body (702), transmissions from other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network, are broadcast from corresponding headphones connected to headphone jacks (518), (718) or (916), respectively, depending which communications modules are in use.
[0125] Holding (for approximately 6 seconds) intercom button (812) of replaceable advanced selection panel (800) deletes the secure intercom wireless network security code from memory unit (736) of advanced communications module (700), so that advanced communications module (700) is free to connect with a new secure intercom wireless network.
[0126] For an advanced communications module (700) connected to media device (724) with a 3.5 mm conventional auxiliary wire, wireless media connection module (733) need not be activated. For an advanced communications module (700) with a direct connection to media device (724), holding media button (814) for approximately 2 seconds turns on or off the direct connection to media device (724). Quickly pressing media button (814) activates voice recognition capabilities in smart phones, smart listening devices, smart tablets, and other similar smart electronic devices comprising media device (724), to facilitate making phone calls, listening to music, and otherwise activating media device (724) functionality.
[0127] Depending on which face protector is selected for use, interior microphone (110) of half-mask face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the signal goes through audio processor (730) to squelch and clarify an operator's muffled or otherwise distorted voice to media device (724). If headphones are not connected to headphone jack (718) of advanced communications module main body (702), then transmissions from media device (724) are broadcast from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. Alternatively, if headphones are connected to headphone jack (718) of advanced communication module main body (702), then media device (724) headphone broadcast is sent to the separate headphones. While the direct connection to media device (724) is on, phone calls made to media device (724) will ring advanced communications module (700), and pressing media button (814) of replaceable advanced selection panel (800) will answer the phone call. Pressing media button (814) again quickly will disconnect the phone call.
[0128] For an advanced communications module (700) without a wireless media connection module (733) connection to a media device (724) established, holding media button (814) for approximately 4 seconds activates advanced communications module (700) wireless media connection module (733) handshaking to establish and memorize a secure connection with wireless media connection module (733) enabled media device (724). For an advanced communications module (700) with a wireless media connection module (733) connection to media device (724) memorized, holding media button (814) for approximately 2 seconds turns on or off the wireless media connection module (733) connection to media device (724). Quickly pressing media button (814) activates media device (724) voice recognition capabilities, to facilitate placing phone calls, listening to music, or otherwise accessing media device (724) capabilities. Depending on which face mask is selected for use, interior microphone (110) of half-mask face protector (100), or interior microphone (212) of full-mask face protector (200), is activated and the signal goes through audio processor (730) to squelch and clarify an operator's muffled or otherwise distorted voice to media device (724). If headphones are not connected to headphone jack (718) of advanced communications module main body (702), then transmissions from media device (724) are broadcast from exterior speaker(s) (112) of half-mask face protector (100), or exterior speaker(s) (214) of full-mask face protector (200), depending on which face protector is selected for use. Alternatively, if headphones are connected to headphone jack (718) of advanced communications module main body (702), then the media device (724) headphones broadcast is sent to the separate headphones.
[0129] While the wireless media connection module (733) connection to media device (724) is on, phone calls made to media device (724) will ring advanced communications module (700), and pressing media button (814) will answer the phone call. Pressing media button (814) again will disconnect the phone call. Holding media button (814) for approximately 6 seconds deletes the secure connection between media device (724) and wireless media connection module (733), so that advanced communications module (700) is free to connect with another media device (724).
[0130] If a 3.5 mm auxiliary wire is connected to the auxiliary jack (720), the control unit (728) will default to connecting with the media device (724) using the 3.5 mm auxiliary wire connection rather than the wireless media connection module (733).
[0131] Advanced communications module (700) may be connected to a conventional USB power source to charge a power supply (734) battery, or may be connected to a computer to charge a power supply (734) battery or upload firmware updates to control unit (728) and corresponding audio processor (730). For instance, upgraded control unit (728) firmware may comprise upgraded programming to facilitate bug fixes and additional functionality. Upgraded audio processor (730) firmware may comprise upgraded programming for bug fixes to squelch, background noise filtering, and clarification of an operator's muffled or otherwise distorted voice.
Handheld Communications Module (900)
[0132] Handheld communications module (900) allows an operator to use built-in microphone (902), speaker (904) (or a conventional headset microphone and headphones), and a wireless transmitter/receiver as an intercom to facilitate communications at a relatively longer distance (as compared to basic communications module (300)) between other users of intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900). Such communications may occur between operators in separate rooms or on separate floors of a location, and under similar conditions where operators are out of the line-of-site of other operators.
[0133] During use of handheld communications module (900), a plurality of indicator light-emitting diode devices (906), which are positioned on handheld communications module (900), indicate the status of handheld communications module (900) functionality. More specifically, light-emitting diode devices (906) indicate handheld communications module (900) status displaying different colors, each color corresponding to the functional state of handheld communications module (900). For instance, plurality of light-emitting diode devices (906) function as follows to display status indicator colors: glow blue when handheld communications module (900) power is on; slowly blink blue when handheld communications module (900) is in use; rapidly blink blue when handheld communications module (900) is in wireless handshaking mode; blink red when handheld communications module (900) is charging; glow red when handheld communications module (900) is fully charged but the power charger is still attached; and blink alternating red and blue when handheld communications module (900) encounters an error, such as if intercom button (912) is pressed to connect with a wireless network without having been first established as part of a wireless network.
[0134] Pressing power button (908) turns handheld communication module (900) on and off. Pressing volume buttons (910) adjust up or down the volume of built-in speaker (904), or conventional headphones that are connected to headphone jack (916). For a secure intercom wireless network unestablished handheld communications module (900), holding intercom button (912) for approximately 3 seconds activates wireless handshaking to establish a secure connection with another unestablished intermediate communications module (500), advanced communications module (700), or handheld communications module (900), which is concurrently in handshaking mode as well. Two unestablished intermediate communications modules (500), advanced communications modules (700), or handheld communications modules (900), will agree on a security code to establish their own new intercom wireless connection. One established intermediate communications module (500), advanced communications module (700), or handheld communications module (900) will connect with an unestablished intermediate communications module (500), advanced communications module (700), or handheld communications module (900) to inform it of the established intercom wireless network connection's security code. In this way, two established intermediate communications modules (500), advanced communications modules (700), or handheld communications modules (900), can expand the secure intercom wireless network to additional users of intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900).
[0135] For a secure intercom wireless network established handheld communications module (900), pressing an established handheld communications module (900) intercom button (912) once quickly send a call out to other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), in range that are using a similar security code to connect with as part of the intercom wireless network. Pressing intercom button (912) again once quickly will disconnect that one intermediate communications module (500), advanced communications module (700), and handheld communications module (900) from the concurrently connected intercom wireless network. If neither microphones nor headphones are connected to headphone jack (916), built-in microphone (902) is activated and the signal goes through audio processor (924) to clarify the operator's voice and broadcast the operator's voice to other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900) on the secure intercom wireless network.
[0136] Alternatively, if a microphone and headphones are connected to headphone jack (916), then the microphone corresponding to the headphones is activated and the signal goes through audio processor (924) to clarify an operator's voice and broadcast the operator's voice to the other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network. If a microphone and headphones are not connected to headphone jack (916), then transmissions from other intermediate communications modules (500), advanced communications modules (700), and handheld communications modules (900), on the secure intercom wireless network are broadcast from built-in speaker (904). If a microphone and headphones are connected to headphone jack (916), then transmissions from other advanced communications modules (700) on the intercom wireless network are broadcast from the headphones. Holding intercom button (912) for approximately 6 seconds deletes the secure intercom wireless network code from memory unit (930) of handheld communications module (900), so that handheld communications module (900) is free to connect with another intercom wireless network.
[0137] Handheld communications module (900) may be connected to a conventional USB power source to charge a power supply (928) battery, or may be connected to a computer to charge a power supply (928) battery or upload firmware updates to control unit (922) and corresponding audio processor (924). For instance, upgraded control unit (922) firmware may comprise upgraded programming to facilitate bug fixes and additional functionality. Upgraded audio processor (924) firmware may comprise upgraded programming for bug fixes to squelch, background noise filtering, and clarification of an operator's muffled or otherwise distorted voice.
