[0002] CROSS-REFERENCE TO RELATED APPLICATION

[0003] This international application claims priority to US Provisional Application No. 63 / 425,167, filed November 14, 2022, which is hereby incorporated by reference in its entirety.

[0004] FIELD OF THE INVENTION

[0005] The invention relates to modular communication devices for use with mouth, nose, face, and head coverings, including masks and hoods, as well as non-invasive ventilation (NIV) masks or respirators. Modern societal health concerns often require the use of such coverings and / or masks to protect a wearer from exposure to external air, liquids, particulate, pathogenic, or other harmful substances. Although masks and hoods may protect a wearer, they also hinder communication by reducing or muffling the wearer’s voice. The disclosure provides modular communication devices that can be attached to or interfaced with a disposable or reusable mask or hood, and allow a user’s voice to be amplified outside of the mask or hood for communication with third parties. The disclosure also provides for systems and devices capturing a respirator, mask, or hood wearer’s voice at a respirator or within a fluid delivery tube, said systems and devices rebroadcasting or amplifying the wearer’s speech for communication with third parties. Communication devices and related systems and methods may advantageously involve sound output profiles to compensate for speech sound transmission losses through a mask, face covering, respirator, or hood. Sound output profiles and additional features including voice transcription and / or recordation may be included in or by such communication devices, a connected mobile computing device application, or an internet-connected server / cloud.

In the case of conflict, the present description will control.

[0182] As was noted above, the present disclosure, in some embodiments, relates to a patient respiratory mask that includes a microphone disposed thereon, the microphone is configured to interface with a wired or wireless speaker and / or a wired or wireless communications device, such as a telephone. In some embodiments, the present disclosure relates to modular communication devices for use with mouth, nose, face, and head coverings, including masks. The disclosure provides for a modular communication device that can be attached to a disposable or reusable mask or face covering and allow a user’s voice to be amplified outside of the mask. While the following is described in reference to various exemplary embodiments, the present disclosure is not so limited.

[0183] In some exemplary embodiments, the microphone is a noise-cancelling microphone. In further embodiments, the microphone includes or is associated with at least one noise filter. In further exemplary embodiments, one or more of the microphone, speaker and communications device is wireless. It is to be understood that reference to a component, such as a microphone, speaker, etc., as being wireless or transmitting wirelessly encompasses configurations wherein such device is connected to a component that includes a wireless transmitter and / or receiver. Accordingly, any reference herein to a "wireless" component should be read to encompass such a construction. In further exemplary embodiments, an on-board speaker is integrated into a portion of the respiratory mask. In further exemplary embodiments, a speaker is external to the mask.

[0184] As we have noted, in exemplary embodiments, the patient respiratory mask includes an internal and / or coupler- or tube-adapted noise-cancelling microphone with wireless, e.g., Bluetooth®, capability. In exemplary embodiments, the microphone is attached to or built into a respiratory mask, a coupler designed to attach to the mask tube interface, or mask fluid delivery tube (e.g., for oxygen, air or some other gas). In additional exemplary embodiments, the coupler includes one or more of a microphone, a speaker, wiring, processor and a communications device. In exemplary embodiments one or more of the preceding elements are embedded in or provided through a portion of the coupler.

[0185] As discussed above, further exemplary embodiments, the microphone wirelessly transmits a patient's voice, via Bluetooth® technology, to a Bluetooth® speaker in proximity to and in communication with the Bluetooth® transmitter. Reference herein to a "Bluetooth®" device refers to a device that is enabled to use Bluetooth® technology. In further exemplary embodiments, the microphone wirelessly transmits a patient's voice, via Bluetooth® technology, to a Bluetooth® smartphone in proximity to and in communication with the Bluetooth® speaker and / or Bluetooth® transmitter. While a Bluetooth® speaker and an exemplary Bluetooth® smartphone are specifically described, the present disclosure contemplates other Bluetooth® communications devices.

[0186] Referring now to FIG. 1 , one exemplary patient respiratory mask in accordance with the present disclosure includes an exemplary microphone provided therein. In exemplary embodiments, the respiratory mask is a CPAP (or Bl PAP) respiratory mask, shown generally at 10, with a mask portion 12 and a Bluetooth® microphone 14 that is incorporated within a fluid airspace, shown generally at 16, of the mask 10 near the mouth (not shown) of a patient. The exemplary mask also includes a fluid delivery tube 18 and at least one mask inlet 20.

[0187] In exemplary embodiments, the microphone 14 is mounted on or is provided within the material of the mask. In another exemplary embodiment, the microphone is provided in a separate microphone tube (not shown) that may extend at least partially into the fluid airspace of the mask 10. For example, the microphone tube may be formed as a portion of a coupler or inserted into a mask or coupler. A microphone tube is generally positioned within or in proximity to the interior airspace of the mask, coupler, or fluid delivery tube. In some embodiments, a microphone tube is removably insertable into a port or opening on a respiratory mask, mask, PAPR hood, etc. A microphone tube generally has a tubular structure containing a microphone disposed within the tube such that the tube collects sound to be picked up by the microphone. In further exemplary embodiments, the microphone tube is at least partially sealed, for example via plastic or a membrane that is at least moderately transparent to sound but that also separately maintains the integrity of the fluid airspace 16 within the respiratory mask 10.

[0188] Such an exemplary microphone tube may be provided within or be mounted to the respiratory mask 10, a fluid delivery tube 18, or any coupler 22 or portions intermediate the fluid delivery tube 18 the respiratory mask 10.

[0189] Referring now to FIG. 2, another exemplary patient respiratory mask 10 incorporates such Bluetooth® microphone 14 into a coupler device 22 that is positioned between the fluid delivery tube 18 and the respiratory mask 10. In exemplary embodiments, the coupler 22 is sized and configured to provide a friction fit for the mask inlet 20 on one side and for the fluid delivery tube 18 on the other side. Referring to FIG. 3, an exemplary coupler 22 includes a mask inlet side, shown generally at 32, a fluid supply tube side, shown generally at 34, with bulk air flow traversing the interior of the tube generally at the arrows of 36.

[0190] In an exemplary embodiment, a microphone 14 is separated from the bulk air flow 36 by a filter 38, which may be configured to filter one or more sound characteristics or to simply shield the microphone from bulk air flow. The filter 38 may be a membrane, acoustic mesh, or any other convenient sound transmitting material.

[0191] In the illustrated exemplary embodiment, the microphone is illustrated as being operatively connected to a microphone pre-amplifier 40, an equalization component 42 [for example an analog to digital converter (ADC) and digital signal processor (DSP)], a Bluetooth® transmitter 44, a sound output component, such as a digital to analog converter (DAC), amplifier (Amp) and speaker 45, an antenna 46 and a power supply 47, such as a battery or wired power adapter. These components are illustrated in this exemplary embodiment as being both connected to the microphone and as being housed on a protruding portion 48 of the coupler 22. However, it should be recognized that the microphone may be configured on-board the coupler 22 with more or fewer associated components, with some components or processes omitted or performed elsewhere, e g., on the exterior of the coupler 22, remote from the coupler 22, etc.

[0192] Additionally, the coupler can take any convenient shape when housing such components, as long as connecting portions 32 and 34 are configured to connect to the mask inlet 20 and the fluid delivery tube 18, respectively.

[0193] In exemplary embodiments, the coupler may be configured to attach to the fluid delivery tube, regardless of any variation in tube diameter (e.g., differences in configurations warranting use of a 19mm inner diameter standard tube vs. a 15mm inner diameter thin tube). Thus, exemplary embodiments provide a universal attachment (e.g., as a clip on, etc., as shown in FIG. 4) configured to fit a wide array of tubes and breathing apparatuses.

[0194] In other exemplary embodiments, the microphone or other electronic components are configured to attach externally (for example as a clip-type attachment, among others) to the respiratory mask 10 but in close proximity to the patient's fluid airspace (see 16 in FIG. 1 ). Referring now to FIG. 4A, a clip 50 is illustrated with a microphone unit 14 provided on an underside of the clip. In exemplary embodiments, the clip 50 also interfaces with a power and signal wire 54 via a port 56. While such a clip may be configured to attach anywhere that is convenient to place the microphone unit 14 near a sound transmitting surface, for example the inlet portion 20 of mask 10 or an exterior portion of a coupler 22, FIG. 4 illustrates provision of the clip 50 over a portion of the fluid deliver hose 18, with the microphone unit against or proximate the material of the hose to pick up sound vibrations transmitted through the hose. It should be recognized that while FIG. 4 illustrates a wired configuration, the microphone unit can also be configured with a battery and a wireless (e.g., Bluetooth®) transmitter. FIG. 4B illustrates an exemplary side elevation view of the clip 50, with microphone 14 positioned to be near tube 18 in an installed position. Referring now to FIG. 5, a fluid delivery tube 18 is illustrated as including an integrated coupler 22 that incorporates a microphone 14 (see FIG. 2) therein and is attachable to or integral to respiratory fluid delivery tube 18. An exemplary power cord 24 runs at least along a portion of the tube 18 to the microphone 14 (which may be configured in a wired or wireless, e.g., Bluetooth®, arrangement). As we have noted above, the coupler may also include other components, such as processing or filtering components, a wireless transmitter, etc., in addition to or alternative to the microphone, such as a speaker, wiring or any other type of communications device.

[0195] In further embodiments, the microphone 14 may be configured as a wired microphone utilizing the exemplary cord 24 or another cord for data transmission. In additional exemplary embodiments, the microphone may be wireless and may be connected to a battery source, with no cords running along a portion of the tube 18.

[0196] In further embodiments, a cord can be configured with one or more clips to secure it to the hose 18 or as an integral part of the hose 18, for example embedded or permanently attached to the tube 18 or to a tube wiring harness. Exemplary wire harness clips 62 are illustrated as attaching a cord 24 to tube 18 in FIG. 6. In exemplary embodiments, the cord 24 is configured as a wiring harness secured at one or more places via harness clips 62, with the cord connectable to a coupler 22 (as in Figs. 2 and 3) or a mask (as in FIG.1 ). For any wired configurations, the remote (from the mask) end of the cord 24 may be configured to connect to additional components, such as a speaker, processor, network, power, etc.

[0214] In embodiments, when the user (patient) of the respiratory mask speaks, the user’s voice will be captured by the noise canceling microphone as the sound hits the interior structure of the mask and / or travels down the tube. Once the voice is captured in the device, it is transferred via Bluetooth® technology to a free-standing speaker where their voice will be amplified. In other exemplary embodiments, the voice is transferred to a speaker on the mask, coupler or tube where the voice will be amplified. In other embodiments, the system is configured to distinguish between direct human interaction (conversation) and digital interaction (e.g., voice signals from a mobile phone) and automatically switch output to one of plural possible wireless communications devices depending on the detected signal. Alternative automatic or manual switching is further contemplated herein with regard to exemplary embodiments, for switching between a nearby Bluetooth® speaker and a communications device (e.g., a mobile telephone, facilitating patient conversation with a remote individual). In other embodiments, multiple Bluetooth® devices may be connected at the same time via bridging capabilities. Such a switching or bridging capability may be e.g., provided alongside the microphone or anywhere in range of the Bluetooth® microphone. In other embodiments, multiple Bluetooth® devices may be connected at the same time via multiple connections or modes.

[0215] It will be apparent to those skilled in the art that, while embodiments have been shown and described, various modifications and variations can be made to the invention disclosed herein without departing from the spirit or scope of the invention. Also, the exemplary embodiment described above should be read in a non-limiting fashion, both with regard to construction and methodology. Accordingly, it is to be understood that the various embodiments have been described by way of illustration and not limitation.

[0216] In an embodiment, the device may be a communications device dimensioned and configured to be used with a mask, or other device that is intended to cover a user’s face, nose, mouth and / or head. Commonly used face masks make communication more difficult by lowering and muffling a user’s voice. Wearing masks may reduce inherent effectiveness of the mask by requiring mask wearers to stand closer together, shout, or remove the mask to adequately communicate. The disclosed communication device when combined with a mask, allows disposable or reusable masks to improve the user’s communication from a safe distance as well as when using a phone or other communication device.

[0217] A mask may be made of cloth, paper, cardboard, plastic, or other material. The mask may be used to conceal a user’s identity, prevent the dissemination of the user’s breath or expelled gases, liquids, or particulates. The mask may also protect the user from inhaling, or receiving on the face, other gases, liquids, or other particulates. Examples of masks include those selected from the group consisting of a cloth mask, fabric mask, disposable mask, single-use mask, surgical mask, procedure mask, medical mask, plastic mask, dust mask, filter mask, respirator mask, respiratory mask, oxygen mask, KN95 mask, N95 mask, surgical N95 mask, N99 mask, KN99 mask, N100 mask, KN100 mask, R95 mask, P95 mask, P100 mask, PM2.5 mask, FFP1 mask, FFP2 mask, FFP3 mask, a CPAP mask, a BiPAP mask, multilayered mask, mask with removable filter, a face covering, handkerchief, kerchief, veil, hood, bandana, mask with fitter, mask with brace, and combinations and layered arrangements thereof.

[0218] The communication device may be removably attachable to a disposable or reusable mask, which is particularly helpful to medical professionals, patients, first responders, or anyone who desires to cover their nose and mouth and / or filter the air they breathe or expel. The communication device may be reusable so that it may be removed from a first mask to subsequent masks. In an embodiment the communication device may be modular with multiple parts allowing it to attach to a mask. The communication device may include inner and outer housings, or just one inner or one outer housing. The communication device may be autoclavable or sterilizable, or disposable.

[0219] The inner and outer housings of the communication device may each include all other necessary components for successful operation of the communication device. The housings may be constructed of any reasonable material for commercial, personal, or medical devices, such as plastics, metals, woods, or man-made or natural materials. Each housing may also include elements to secure the inner and outer housings to the mask, and to create a connection between the inner and outer housings. In orderto connect the inner and outer housings to the mask, the inner and outer housings may include a mechanical clip, a spring, a magnet, pins, hook and loop, snaps, buttons, glue or other adhesives, zippers, stitches, strings, ties, staples, suction, or other connective means. Certain features (e g. snaps, buttons, zippers) may be complementary to features on the mask. The housings may be configured to slip into and reside in a pocket or other means for securement on the mask. The inner the outer housing may be configured to attach to eyeglasses, a hat, or other wearable item which allows the inner housing to be in close proximity to the user’s mouth or nose.

[0220] The inner and outer housings may each include complementary magnetic attachments which allow the inner and outer housing to attach to one another, separated by the mask. Magnetic attachments create a secure and movable connection on the mask. The magnetic attachments may be a ring on each housing, which creates a secure connection between the inner and outer housing, and securely attaches the communication device to the mask. The complementary magnetic attachments pair to one another across the mask, yet still allow electrical signals to pass between the inner and outer housing. The complementary magnetic attachments may be a ring, or a square, or any other shape with an open center. The complementary magnetic attachments may also be a plurality of complementary magnetics on each of the inner and outer housings. The complementary magnetic attachments may have the ability to attach designs or otherwise showcase messages to the outer housing as a form of free speech or advertising.

[0221] The inner and outer elements may also be dimensioned in a curvilinear form, complementary to each other. The curvilinearform of the inner element may be placed inside the mask extending from one side to the other crossing the area in front of the user’s mouth. A speaker may be located in a central location between the sides so that it is close to the user’s mouth. Other features, such as electrical and attachment features, of the inner element may be located along the curvilinear form flanking the microphone. The curvilinear outer element may attach to the inner element by magnetic attachments at locations complementary to the inner element. In other embodiments, the elements may be part of, or attached to, an inner support frame / bracket that supports the form of the mask on the user’s face.

[0222] The inner and outer housings may contain a power source. The power source may be in both housings, or the power source may be in only one of the housings. The power source may be a replaceable or rechargeable battery. Because of the close proximity of the housings, power may flow, via induction or other modalities, from the powered housing to the non-powered housing, through the mask. Alternatively, a physical connection, as described above, may span between the inner and outer elements to provide power to the non-powered element or exchange data between the elements. In it also contemplated that the device may mate with a mask having an existing port (for airflow, etc) allowing a suitable path for a physical connection between the inner and outer elements.

[0223] One or both of the inner and outer housings may include a port and / or cable for a power source or power charging, or for data transfer. The port and / or cable may connect the housing, the element, and the device to another system for data or signal processing, charging, external speakers or communication, or any other relevant system.

[0224] The inner element may be located inside the mask in close proximity to the user’s mouth, to easily pick up the user’s voice. The inner element may act as or include a microphone and a transmitter. The inner element may transmit a signal, of the user’s voice, to the outer element. The outer element may be releasably attachable to the outside of the mask. The outer element may include a transmitter, a receiver, and a speaker, to receive the signal from the inner element and then project the user’s voice. The user’s voice may be projected via the speaker in the outer housing or the inner or outer housings may also transmit the voice signal to an external speaker or system. The speaker in the outer housing may project the user’s voice along or in combination with an external speaker or system. The microphone, speaker, and electrical processing may include any of the elements described above. The speaker may include a flared housing, such as a bull-horn to increase the user’s voice. The transmission of signal between the inner element and the outer element may be wireless or may be via a physical connection between the elements. A wireless transmission between the inner and outer elements is suitable for a reusable mask or disposable mask. The transmission of electrical signal through the physical connection may include an element, extending from the inner or outer element, that pierces through a disposable mask and makes a physical and electrical connection with the other of the inner or outer element. This connection is suitable for a disposable mask or may be used with a reusable mask.

[0225] In the communication devices and systems herein, masks, hoods, or other face coverings may have various built-in aspects for engagement or interfacing with the communication devices and systems. Masks, hoods, or face coverings may have a built-in magnet or metal magnetic attachment, to which a magnetic portion of a communication device can releasably engage. Built-in magnets or magnetic attachments may eliminate the need for an internal housing, mask clip, or any other piece inside the mask. Alternatively, the magnet or metal may be insertable into the mask. For example, a mask may contain a slit for inserting a magnet or metal, or a standard disposable or multi-layer reusable mask may be slit by a knife to insert a magnet or metal, followed by taping overthe slit. It can be appreciated that any manner of incorporating a magnet or metal into a face mask or hood is contemplated. In an alternative embodiment, a microphone may be built into a mask, or may be built into any other face covering or hood as a one-time use device. For example, the microphone may be embedded in a disposable face mask and may have a wire connector exiting the mask for connection to a speaker or interface device. Alternatively, the microphone embedded in the mask may be wireless. In another embodiment, the microphone embedded in the mask may be wireless and disposable or wireless and rechargeable. In another embodiment, the microphone may be waterproof and the mask may be reusable, washable, and / or sterilizable. Alternatively, the microphone may be insertable into the mask. For example, a mask may contain a slit for inserting a microphone, or a standard disposable mask may be slit by a knife to insert a microphone, followed by taping over the slit. It can be appreciated that any manner of incorporating a microphone into a face mask or hood is contemplated.

[0226] In an embodiment, a mask or hood may include a built-in sound waveguide, such as a sound transfer pad. Such a sound waveguide optimizes the collection of sound within the mask or hood and routes it to an attachment area coupled to the waveguide, where a portion of a communication device connects to pick up the sound. The connection between the communication device and the attachment area may be a connector, adhesive, magnetic, or any other suitable connection. The attachment may be a physical connection placing a microphone or piezoelectric pickup in proximity to the attachment area and / or waveguide. Optionally, the mask or hood may include a microphone or piezoelectric pickup coupled to the waveguide, and the communication device may interface electrically with the microphone or piezoelectric pickup.

[0227] The mask or hood may alternatively include a clip, pouch, slot, or other complementary feature to a housing of the communication device so that the device may interface with the mask or hood. In an embodiment, a communication device may comprise a microphone in a first housing (e.g. FIGs. 12 - 13), where the first housing, instead of comprising magnetic attachments, is configured to interface with a built-in portion of a mask or hood. Generally, such a built-in connector would position the microphone to substantially face the mouth of the wearer of the mask order to pick up speech from the wearer.

[0228] In further alternative embodiments, a mask or hood may comprise all components necessary to pick up and amplify the speech of a wearer. For instance, a mask or hood may comprise a microphone, speaker, power source, and any analog or digital circuitry necessary to project the user’s voice from the speaker. One or more such components may be incorporated permanently or removably in the mask or hood, the remaining components being arranged within one or more housings of a communication device. As described herein, one or more housings of a communication device may releasably attach to a mask or hood.

[0229] The embodiments disclosed herein are generally useful with hoods, such as PAPR hoods. A “PAPR hood” is the portion of a powered air purifying respirator that a user may wear for protection from environmental or biologic hazards. Such hoods generally surround a wearer’s head or head and neck and are connected with an external, filtered positive pressure source, such as a battery-powered positive pressure source. PAPR hoods are generally fitted with a flexible or semi-rigid transparent plastic window such that the wearer can see, and such that the wearer’s face is visible from the exterior. The terms “PAPR hood” or, more generally “hood”, are intended to encompass any hoods, respirators, or similar safety or medical apparatuses which cover the head or face of the user to provide filtered or positive pressure air to the user. For example, the communication devices herein are contemplated for PAPR hoods, respirators, and any other type of hood.

[0230] Embodiments herein may attach to such a hood using a mechanical clip, a spring, a magnet, pins, hook and loop, snaps, buttons, glue or other adhesives, zippers, stitches, strings, ties, staples, suction, or other connective means. Certain features (e.g. snaps, buttons, zippers) may be complementary to features on the hood. Magnetic attachments as disclosed herein are generally useful for releasable attachment of a housing to the transparent window of a PAPR hood. Various “attachment portions” are contemplated for engaging with a portion of a communication device.

[0231] In some embodiments, a first housing having a microphone is provided in wired or wireless connection to a second housing having a speaker (see, e.g., FIGs. 12 - 13), although any described communication device configurations are contemplated. In some embodiments, a first housing comprising a microphone is releasably attachable with a mask or hood. In some embodiments, a first housing comprising a microphone is releasably attachable to the transparent window of a PAPR hood. In some embodiments a second housing having a speaker may include a mechanical clip, a spring, a magnet, pins, hook and loop, snaps, buttons, glue or other adhesives, zippers, stitches, strings, ties, staples, suction, or other connective means for engagement with an article worn on a person.

[0232] In some embodiments, a first housing having one or more of a microphone and / or speaker may be releasably attachable to a mask or hood by a snap connector attachment portion. Snap connectors generally have a circular stud engageable with a complementary socket. In an exemplary embodiment, a hood or mask may comprise a stud or socket of a snap connector engageable with a complementary stud or socket on a device housing, such as a first housing comprising a microphone. The stud or socket on the hood or mask may be permanently attached, built-in, or releasably attached. The stud or socket may be attached to an adhesive pad. Such an adhesive snap connector attachment portion may be adherable to a mask or hood, such as to the transparent window of a PAPR hood. FIG. 27 shows an example of a stud with an adhesive pad and a socket-type connector complementary to the stud. In some embodiments, communication systems include a mask or PAPR hood having a built- in or releasably-securable connector (i.e. attachment portion), and a communication device comprising one or more housings, where one of the housings has a connector complementary to the connector on the mask or PAPR hood.

[0233] In some embodiments, a mask or PAPR hood comprises a built-in magnet attachment portion. For example, a mask or PAPR hood may comprise a magnet, a ferromagnetic material (such as a metal or iron), or a ferrimagnetic material. For simplicity, the term “metal” will be used to refer to a ferromagnetic or ferrimagnetic material engageable with a magnet. The mask or PAPR hood may have a permanently-attached, embedded, or adhered magnet or metal attachment portion complementary to a magnet or metal on a housing of a communication device. In some embodiments, a communication device may have a first housing having a microphone, the housing having a magnet disposed on an exterior surface complementary to a magnet or metal attachment portion associated with a mask or PAPR hood.

[0234] For example, as shown in FIG. 28, a PAPR hood may comprise an embedded, attached, or adhered portion for releasable engagement with a portion of a communication device. Likewise, any other type of mask may comprise an embedded, attached, or adhered portion for releasable engagement with a portion of a communication device. While the outlined portion in FIG. 28 is shown at a particular position on a PAPR hood window, it can be appreciated that any adhered or otherwise attached portions can be located at any useful position (generally to place a microphone in proximity to a user’s mouth).

[0235] In some embodiments, a magnet or metal complementary to a magnet may be adhesively attached to an interior or a mask or PAPR hood window as an adhesive attachment portion. FIG. 29 shows an exemplary embodiment of an adhesive attachment portion containing or embedding a metal or magnet. The adhesive portion generally has a flexible support coated with adhesive on one side. The metal or magnet is generally located at the surface of the adhesive side or embedded within the adhesive portion. The metal or magnet is optionally coated with the adhesive. The adhesive portion may be a one-time use, optionally sterile, portion for adhering to an interior of a PAPR hood window. Advantageously, the adhesive portion can be placed in any position on the PAPR window interior such that a magnetic (or alternatively metal-containing) portion of a communication device may be releasably engaged with the metal or magnet of the adhesive portion to secure the magnetic portion of the communication device to the PAPR window. The adhesive securement ensures that the attachment portion cannot become loose or free within the PAPR hood or mask during use, or if the communication device is removed.

[0236] In an embodiment, a system includes a PAPR hood, an adhesive attachment portion having an embedded metal or magnet, and a communication device having a metal or magnet complementary to the embedded metal or magnet. In an embodiment, the metal or magnet of each of the adhesive attachment portion and communication device are complementary ring-shaped metal or magnets surrounding the microphone or microphone aperture in the housing of the communication device. In an embodiment, a PAPR hood may include a sound-transmitting surface for attachment of a communication device. A sound-transmitting surface may be a PAPR hood window, a separate portion of the hood, or a portion of the PAPR hood window which is the same or different material from the remainder of the PAPR hood window. In an alternative embodiment, the metal or magnet is coated directly with an adhesive for securement to the inside surface of the PAPR hood window.

[0237] In an alternative embodiment, the communication device is secured against the other (outside) face of the PAPR hood window by a screw or bolt, with a nut fastener at the other side. The nut fastener or communication device may comprise a gasket around the screw for an airtight seal. When the communication device is not in use, a plug or seal may be used to keep the hole in the PAPR hood window airtight. Alternatively, a bracket may screw to the PAPR hood window allowing a housing of the communication device to dock against the PAPR hood window (for example, a microphone housing). A bracket or docking connector may alternatively be formed as a portion of a PAPR hood or PAPR hood window to allow the housing to dock in position for use.

[0238] FIG. 30 depicts an exemplary embodiment of a microphone portion of a communication device being releasably attached to the window of a PAPR hood. As disclosed herein, the microphone portion is generally a microphone contained within a housing configured to pick up the voice of the user through the mask or PAPR hood. In the depicted embodiment, a first housing releasably attached to the window of a PAPR hood contains at least a microphone, and the first housing is in wired orwireless connection with a second housing containing at least a speaker. The microphone and speakerare operably connected as disclosed herein. In alternative embodiments, both of the microphone and speaker may be releasably attached to the PAPR hood window, the microphone and speaker being contained within the same or separate housings.

[0239] Further attachment types are contemplated, for example, attachments which do not require a separate attachment portion on the mask or hood to engage with a housing of a communication device. In an embodiment, a microphone may be provided in a housing configured to adhesively attach to an outer surface of a PAPR hood window. FIG. 31 depicts an embodiment having a microphone housing with a raised lip for engagement with an adhesive portion.

Generally, any communication protocol is useful including RF, Wi-Fi, Bluetooth, 5G, other cellular protocols, etc. In an embodiment, the microphone module is capable of being docked into the speaker module for storage and / or charging. In an embodiment, the microphone and speaker modules separately, or together, dock into a further module supporting storage and charging, and / or sterilization, of one or more communication devices. In an embodiment, docking stations are provided for any of the communication devices described herein. An exemplary docking station is depicted in FIGs. 34-35. In the depicted embodiment, a speaker housing (or speaker module) has a clip for attachment to a respirator hose (such as a fluid delivery tube, respirator hose, PAPR hood tube, etc.). A docking station may comprise a plurality of posts for engagement by a clip or other connector of a speaker housing. In an engaged position, the speaker housing may be charged by a wired or wireless charging connection. In an embodiment, a docking station comprises from about 1 - 20 posts, or from about 1 - 10 posts, orfrom about 2- 9 posts. In some embodiments, a docking station comprises 2 posts. In some embodiments, a docking station comprises 5 posts. The docking station may also provide for UV disinfection capabilities. The docking station base and posts may be UV-transparent and allow for UV light generated within the unit to irradiate substantially all surfaces of the speaker housing. Advantageously, the posts also contain UV lighting and irradiate the back of the module and clip to ensure substantial disinfection. In an embodiment, the microphone housing and wire (or, alternatively, a microphone module in wireless embodiments) may also be held within the docking station. In another embodiment, the microphone housing and wire may be removed prior to docking.

[0243] Disinfecting UV light (generally UV-C) can be generated by any suitable light source, including light -emitting diodes (LEDs), fluorescent lamps or other UV-C light sources. Generally, the UV disinfector further includes a UV-blocking lid or cover, the interior surface of the lid or cover being reflective to reflect disinfecting UV light onto contained modules. With the lid covering the unit, disinfecting UV-C is contained within the unit and does not transmit substantially outside of the unit for safety of the user. In an embodiment, the UV disinfector comprises a safety feature such as a button or interlock where the UV disinfector will not emit UV-C until the lid is in place. In an embodiment, the UV-C disinfector further comprises wireless capabilities for interfacing with a user mobile device, computer, or smartphone to control one or more functions of the disinfector or to schedule disinfection runs. In an embodiment, the disinfector comprises a timer, sensor, or combinations thereof for setting an appropriate run time for disinfecting contained devices.

[0244] In some embodiments, the speaker housing has an alternative mechanism such as a pocket clip attachment, a magnetic attachment, a snap or button attachment, etc. A docking station may be configured to accept the speaker housing shape and configuration to store, charge, and / or sterilize / disinfect the housing. In an embodiment, the docking station may comprise a wired charging connection, such as micro-USB, USB-C, lightning, or other charging interfaces such as a spring contact interface.

[0245] The UV disinfecting station may have a lid that is reflective only, or the lid may further comprise LEDs or other IIV-C light sources for irradiating contained devices with the disinfecting IIV-C light. In an embodiment, the lid is detachable from the disinfecting station. In another embodiment, the lid may be hingedly attached to the disinfecting station. In an embodiment, power may be supplied to IIV-C light sources in the hood, if any, by a wire running through a hinge, or by contacts (such as spring contacts or other electrical contacts) that are connected in a closed position only. In an embodiment, the contacts function to both power the lid IIV-C light source(s) and to act as an interlock where no UV-C lights will power on unless the lid is in a closed position with the contacts engaged.

[0246] Medical professional clothing may further be designed to accept a speaker housing during use. For example, medical scrubs often have pockets, but they are large and may sag if an electronic unit is inserted. This creates a risk that the unit may fall out of the pocket while a medical professional is giving care to a patient. A scrub top, for example, may be designed to have a pocket configured to tightly hold the speaker unit on the user’s torso. A pocket may be located generally on the chest region of the user, and may further have a zipper, snaps, buttons, or Velcro to hold the pocket in a closed position while the speaker unit is contained. In some embodiments, the pocket is compatible with wired devices and contains a passage for the wire connecting the speaker housing to the microphone housing. The pocket, generally constructed from the same materials as the clothing, may have one or more perforations or soundtransmitting panels to enhance projection of the user’s voice. In a further embodiment, the speaker module may take on other forms useful or desirable in a medical setting. For example, medical professionals must already wear identification while giving care in a hospital setting. The ID speaker module may be configured to also hold the necessary identification card for the medical professional. In an exemplary embodiment, as depicted in FIG. 36, an ID speaker module may have a front panel which is transparent to allow for the identification card to be displayed. The front panel may be removable from the device to allow the ID to be placed, or it may be fixed in position and the ID inserted from a slot on the side or bottom of the device. Generally, one ormore speakers will face the same direction as the ID card. One or more speakers may be held within the ID speaker module and may project sound through perforations at the front of the device. In an embodiment, the ID speaker module further contains a transparent back panel for displaying additional identification or barcodes for medication or supplies access. In another embodiment, the ID speaker module may clip to a ring or contain a clip for mounting on the medical professional’s scrubs or clothing. The ID speaker module may interface with an external microphone and / or speaker by a wired and / or wireless connection. In an embodiment, the ID speaker module may interface with other external devices such as medical monitoring equipment or nurse call lights, the module being equipped with a vibrating function or being configured to play a sound when a medical professional wearing the device should respond or react to a situation.

Such devices may also include a detachable microphone connected to the housing by a cord. A first end of the cord may include a microphone housing including a microphone as further depicted in FIG. 31 and FIG. 32. A second end of the cord may include a connector complementary to a connector on the communication device housing. In an embodiment, the connector at the second end of the cord screws onto the housing connector to form a secure connection. In an embodiment, the microphone and cord are disposable. In an embodiment, the microphone and cord are reusable. The microphone housing generally attaches to an exterior surface of the respiratory mask by clipping to a snap ring, the snap ring attached to the respiratory mask by an adhesive pad. In some alternative embodiments, a first magnetic portion may be adhered to the respiratory mask and a second magnetic portion may be coupled to or formed as a portion of the microphone housing.

[0250] The microphone disposed on a back of the communication device housing (i.e. the housing microphone) and the microphone of the microphone housing at the second end of the cord (i.e. the corded microphone) may be used separately or in conjunction to pick up speech of the user. Advantageously, by placing one microphone on the exterior of the respiratory mask and the other on the fluid delivery tube or coupler exiting the mask, collection of the user speech may be maximized or optimized. Optionally, a front of the communication device may include a third microphone for picking up ambient or environmental noise for noise cancellation. As described herein, signals from the first, second, and third microphones may be used to produce an amplified speech signal for projection by a speaker located on a front of the housing behind a grill or sound-transmitting portion of a front of the housing. Additionally or alternatively, a speech signal may be transmitted by Bluetooth to an external device or speaker for amplification and / or playback.

[0251] In further embodiments, an application (i.e. software) running on a processor may include sound output features and device control features. Capturing speech through a material (such as a mask material) presents unique challenges which are not present in other voice amplification technologies. This is because each type of mask has a unique transfer function which affects the mask wearer’s speech. These transfer functions will affect or degrade characteristics of the use speech, including loudness, frequency response / spectral balance, and coloration / distortion. Therefore, to a third party, the mask wearer’s speech will not only be muffled, but it will also sound differently from their normal voice depending upon the intervening mask material which alter the transfer of different frequency components of the user speech.

[0252] In recognizing this unique challenge, the present disclosure further provides for applications including a profile feature. Respiratory masks from different manufacturers, and different models of masks from the same manufacturers, may have a different shape and construction (material, material thickness, etc.), meaning that they will have unique sound transmission characteristics. In order to correct for the mask wearer's speech altered by the mask. The profile feature includes one or more profiles which correct the user speech to approximate the frequency and loudness characteristics of normal speech without a mask.

[0253] FIG. 39 depicts an audio spectrum showing the sound pressure level (SPL; y- axis), or loudness, as a function of frequency from 100 Hz to 20 kHz (x-axis, log-scale). The figure shows three amplified signals (voice through a cloth face mask, voice through a soft plastic respiratory mask, and voice through a hard plastic respiratory mask) compared to a normal voice level. From the spectrum, it can be seen that the amplified signals overlap well with each other and approximate the spectral shape of the normal voice level across much of the spectrum. As a result, the amplified speech projected by the speaker of the communication device effectively and advantageously mimics the user speech as if there were no intervening mask.

[0254] FIG. 40 depicts an example comparison between the spectral response of voice through a cloth mask with a communication device turned on and off. The spectrum with the device turned on is generated using a mask-specific profile which amplifies frequency components which were muffled by the mask. Further examples are given for a soft plastic respiratory mask (FIG. 41 ) and hard plastic respiratory mask (FIG. 42). In comparing the “off” spectral responses, it is clear that the different mask types have a significantly different effect on the transmitted voice signal. In view of these differences, profiles may be created which can compensate for the negative effects which the mask has on the wearer’s speech.

[0255] In an embodiment, an application contains one or more sound profiles, each for a different type of face mask. In an embodiment, an application includes one or more sound profiles each associated with a different mask material (cloth, paper, fabric, soft plastic, hard plastic, etc.). In an embodiment, an application includes one or more sound profiles each associated with a different mask material and thickness of the material. In an embodiment, an application includes mask-specific profiles for mask models produced by major suppliers.

[0256] The profiles may be pre-loaded into the application, and may be stored in a data store of a device or in a cloud server for retrieval by the application. In an embodiment, the application runs on a process of the communication device. In another embodiment, the application runs on a processor of a mobile computing device, such as a mobile phone, tablet, or laptop computer and the mobile computing device communicates with the communication device over a wireless communication protocol such as Bluetooth or WiFi. The profile may be used to modulate the audio in either of the communication device or a wirelessly (optionally, wired) connected mobile computing device. Where the communication device modulates the audio (i.e. user speech), the communication device may have non-transient data storage such as flash memory for storing one or more profiles and may have transient memory operable with a processor to modulate the user speech audio for projection by the speaker. In alternative embodiments, the speech signal may be transmitted to a mobile computing device for modulation according to a selected profile.

[0257] The profile setting of the communication device may be set in various manners. For example, the communication device may contain a number of pre-loaded profiles which may be set using buttons of the communication device. LED indicators or audio played by the speaker may indicate to the operator (such as the user or hospital staff) which profile is being selected. For example, if ten profiles are pre-loaded, LEDs or speakers may indicate the current profile by a number of blinks or playback of “1 , 2, 3...”, etc. In yet further embodiments, the profile is selected in an application running on a processor of a mobile computing device. The profile may be one of several pre- loaded profiles on the communication device data store, or may be uploaded to the communication device from the application on the mobile computing device over a wireless communication protocol such as Bluetooth or WiFi. The communication device may have additional storage for custom profiles which are not pre-loaded so that the user may obtain additional profiles from a cloud storage.

[0258] An exemplary embodiment is depicted in FIG. 43, although it should be contemplated that variations of this exemplary embodiment are considered. For example, a communication device 4300 as described herein is attached to a mask work by a mask wearer. In an embodiment, the communication device 4300 may be a device such as the device depicted in FIG. 39. The communication device may have one or more microphones 4302 of the communication device which receive user speech audio through a mask material and any airspace between the mask material and the microphone. One or more audio processing circuits 4304 are operably connected with the one or more microphones. The audio processing circuits 4304 may include, for an example, an analog to digital converter (ADC) and optionally a preamplifier. The audio processing circuit(s) are operably connected to a processor 4306 which may modulate the audio signals according to device settings including profiles. Transitory memory (not shown) may be operably connected with the processor 4306 for carrying out the processor functions. A data store 4310 may be operably connected with the processor, the data store including one or more profiles. It should be appreciated that in certain embodiments, a non-transitory data store may be eliminated and transitory memory may temporarily store a profile or aspects of a profile obtained from a linked mobile computing device. However, to more clearly exemplify the profile features, a data store is described.

[0259] These various features including the processor 4306, data store 4310, microphones, speakers, wireless communication circuits, or any other circuit components may be included on one or more printed circuit boards (PCBs). Alternatively, the features may be incorporated into a chip. In various embodiments, the chip may be programmable to or programmed to carry out the described features and functions in various related communication devices.

[0260] The data store 4310 may include one or more pre-loaded profiles 4312. The “profiles” may be alternatively referred to as “speech output profiles.” In the exemplary embodiment of FIG. 43, three pre-loaded profiles 4312 are shown, although more or fewer profiles may be present. In certain embodiments, no pre-loaded or default profiles are present and only custom profiles are present. One or more custom profiles 4314 may optionally be stored in the data store or otherwise used by the communication device 4300. The custom profiles are generally not created by the user but rather are downloaded from a cloud server and are associated with a certain material or type of mask. For example, when a manufacturer begins producing a new mask, a new profile may be optimized for the mask. The downloaded custom profiles allow for older communication devices to be compatible with new masks. Advantageously, the communication devices do not need to be updated with new firmware or hardware because the profiles will be compatible with both older and newer communication devices 4300.

[0261] Again, the data store 4310 may include one or more pre-loaded profiles 4312 or one or more custom profiles 4314. In the exemplary embodiment shown, profile 3 is shown with an “X” indicating that it is selected. To be clear, the selection is an internal device setting stored on transitory or non-transitory memory and is not necessarily displayed on a screen. Although, it is contemplated that some embodiments of communication devices may include a display screen. The set profile may be read out from the communication device in various manners. For example, the communication device 4300 may include LED’s which blink to show the set profile upon a user prompt by buttons of the device. Alternatively, the speaker may audibly indicate the current profile setting, by number or by assigned name or any other identifying label. These features of identifying the set profile via the device are not necessary in all embodiments because an application running on a mobile computing device may be used to display and select relevant information as further described below.

[0262] The communication device 4300 generally will include a wireless communication circuit 4308 for connecting the communication device 4300 to a mobile computing device 4350. The mobile computing device 4350 may be a mobile phone (smartphone), handheld computer, tablet, laptop computer, etc. and will typically have the necessary hardware and software to perform the functions described herein as would be appreciated by a person skilled in the art. The mobile computing device 4350 includes an application 4360 which includes a graphical user interface (GUI) and software instructions for carrying out the functions described herein. The GUI generally displays information to a user or healthcare profession including connection status to a communication device 4300 and the current profile selected. The profiles 4362 displayed in the application 4360 generally correspond to the profiles on the communication device 4300. The mobile communication device 4350 and communication device 4300 may undergo a syncing procedure so that the mobile computing device 4350 can display the profiles loaded onto the communication device 4300. For the purposes of example, the GUI may display the communication device profiles 4362 as well as other profiles which are not currently loaded onto or usable by the communication device. If the user selects a profile which is not present on the communication device, the system may automatically upload the profile to the communication device so that it is immediately usable. The communication device 4300 may have a pre-set number of custom profile slots and one or more custom profiles may be deleted when a new custom profile is uploaded if the profile slots are full. The application 4360 may additionally display “cloud profiles” 4364 to the user or operator. The cloud profiles 4364 may be downloaded to the mobile computing device 4350 from a cloud server 4380 or from another internet-connected location. The difference between custom profiles and cloud profiles is whether or not they have been downloaded for use by the system. In other words, Cloud Profile X, if downloaded, could be added as Custom Profile C, or could replace Custom Profile A or B depending upon user preference. In this manner, updated profiles may be obtained on-the-fly by users so long as an internet connection is present.

[0263] A communication device 4300 may be pre-loaded with certain profiles (for example, a generic hard plastic mask profile, a generic soft plastic mask profile, a generic cloth or fabric mask profile, etc., as well as profiles optimized for marketleading masks that one would expect to encounter in hospital or medical settings. In this manner, a profile having acceptable sound quality may be selected even in situations where internet access is unavailable.

[0264] In yet further embodiments, the application may have features which permit a custom profile to be generated using a specific mask or face covering. For example, the mobile computing device may prompt a wearer to speak a certain sentence and may detect the frequency components of the user speech, with the communication device on or off, by a microphone of the mobile computing device. Alternatively, experienced users may adjust one or more parameters of a given profile in an expert mode of the application 4360 to optimize sound quality.

[0265] Profiles 4362 may include further instructions for display to a user or operator over the GUI. For example, for a specific mask, an optimization may have been performed with one or more microphones 4302 of the communication device 4300 placed in specific positions on the mask. The GUI may therefore direct the operator to place the microphones 4302 in similar or same position on the mask for the optimized collection of user speech. Alternatively, the microphones 4302 may be placed according to general instructions. In yet further embodiments, the application 4360 may include a placement optimization feature which instructs the user to change the position of one or more microphones 4302 if the sound quality (i.e. frequency spectrum of the projected speech) deviates from an expected spectral profile.

[0266] In various embodiments, the “profiles”, alternatively referred to as “speech output profiles” may compensate for the frequency-dependent transmission losses of user speech through the mask. In conjunction with the provided examples, the devices, systems, and methods herein advantageously solve the technical problem revealed that different masks have significantly different spectral or frequencydependent sound transmission profiles. Compensating for these differences is important to more accurately project an output sound which sounds like the user’s voice. Especially in the last moments of life, when many patients may need to wear a respiratory mask, or in emergency situations where a protective mask or hood is required, it is important that the user’s voice is identifiable by loved ones or other personnel. In this context, “compensate” does not necessarily mean that the output speech will exactly match the user speech without the mask, but will approximate a user speech in terms of audio spectrum (frequency). Additionally, “compensate” does not necessarily mean that the amplitude or volume will exactly match the user speech without the mask, and may be similar or louder depending upon the desired amplification level (volume), which may be adjustable by the communication device or connected application on a mobile computing device. Amplification of a sound signal or sound data may be performed at various stages such as, for example, after collection of sound by a microphone but before conversion to a digital signal, after conversion to a digital signal but before a modulation, after a modulation, or at a speaker amplifer / speaker projection stage. These are exemplary and analog devices are also generally contemplated. It is also possible that amplification occurs at some stage in the device function (for example, at a microphone pre-amp) while the speaker volume may still be set at a volume lower than a normal speech level.

[0267] In a general sense, amplification of the speech signal or speech data involves changing the amplitude of essentially all frequency components thereof, while modulation of the speech signal or speech data involves changing the amplitude of less than essentially all frequency components thereof (for example, changing the amplitude of only some frequency components). Advantageously, the profiles or sound output profiles of the disclosure provide for adjusting certain frequency components of the speech signal or speech data depending upon the mask construction material or mask design (model number, size, type, etc.). Additionally, in many embodiments, communication devices may include a microphone placed near a fluid delivery tube or coupling to the mask, as well as a microphone placed on an exterior surface of the mask - in such cases the sound output profile may be optimized for the speech signal or data from microphones in these positions. In some embodiments, the sound output profile is optimized for a microphone configuration (devices with 1 microphone, 2 microphones, etc.) including approximate microphone placement. It should be appreciated that respective sound output profiles for any relevant devices disclosed herein are contemplated. Additionally, it should be appreciated that various aspects of the profiles may be contained or run on the communication device(s), mobile computing device(s), cloud computers or internet servers, etc. to modulate the speech signal to compensate for transmission losses through the mask. In further embodiments, artificial intelligence or machine learning is used to create or optimize one or more profiles. In an embodiment, artificial intelligence is used to create or optimize one or more profiles using one or more inputs selected from: number of microphones, positions of microphones, material of mask, manufacturer of mask, manufacturer model number for the mask, age of patient, sex of patient, patient medical history, patient speech samples from a different audio device, patient speech samples from the communication device, patient speech samples with a profile or filter applied, or any other useful input data. Thus, in further embodiments, provided for are methods for training a machine learning algorithm including one or more said inputs, and methods for optimizing a speech profile using a trained machine learning algorithm. Also provided for are devices and systems including or utilizing machine learning to create or optimize profiles.

[0268] An application of the mobile computing device may perform other functions, including voice recordation and / or transcription. For example, in addition to the communication device projecting amplified speech, the speech signal may be recorded or transcribed by the communication device or, alternatively, the speech signal may be transmitted to a mobile computing device for recordation and / or transcription. Optionally, a profile may be applied to a recorded voice signal so that the voice signal most closely resembles the unmuffled voice of the speaker. Additionally, a profile may be utilized to optimize the voice signal for improved recognition by the transcription program or feature. Transcription may be performed by an onboard speech-to-text program, a speech-to-text program on the mobile computing device, or a speech-to-text program on a cloud computer, or combinations thereof. In certain embodiments, transcription may be displayed on a mobile computing device or other display to enable a patient to communicate with a hearing- impaired third party.

[0269] In various embodiments, the communication devices of the present disclosure may include a housing having or containing one or more microphones. The microphones may be internally-contained or may be disposed near a soundtransmitting portion of the housing. The sound-transmitting portion may be an access hole to allow sound to reach the microphone, and it is contemplated that the microphone may be mounted within such a sound-transmitting portion. The soundtransmitting portion of the housing may also include grilles of a same or different material from the housing, optionally formed as a portion of the housing. In alternative embodiments, the sound-transmitting portion may be a thin or membranous material which does not allow significant permeation of air or fluid but which effectively transmits sound. In some alternative embodiments, if the housing is constructed from a material which adequately transmits sound, the sound-transmitting portion may be a portion of the housing body near which the microphone is mounted in order to capture sound transmitted through the housing. The sound-transmitting portion may be, in various embodiments, placed against or in close proximity to certain mask features (mask surface, fluid delivery tube, coupling between mask and fluid delivery tube, etc.). The “close proximity” should be interpreted as being sufficiently close to collect user speech for operation of the described communication devices. In some cases, “close proximity” could include one or more points of contact between the sound-transmitting portion (or alternatively portion of the microphone if the microphone is disposed in the sound-transmitting portion) and the mask feature. In other embodiments, the sound-transmitting portion of the housing may be located close to, but not touching, the mask feature (such as within about 0.1 - 5 cm, or 0.1 - 2 cm, or 0.1 - 1 cm).

[0270] The communication device may also include sensors for detecting ambient or expelled gas mixtures or temperature. Monitoring gases, like air quality, and temperature may be helpful in respiratory therapy of patients, for first responders, or in any scenario where a user needs a mask. The device may include a separate membrane or filter used to sample or analyze, in real time, ambient or expelled air quality for contaminants, particulates, or pathogens. The membrane may be removable, replaceable, or cleanable. Sensors in the device may include a relative or absolute humidity sensor, a temperature sensor, a dew point sensor, an enthalpy sensor, a pressure sensor, a barometric sensor, a flow rate sensor, an oxygen sensor, a carbon monoxide or dioxide sensor, a nitrogen sensor, or a combination thereof. The sensors may detect or monitor characteristics not associated with air quality, these sensors may include acoustic sensors, light sensors, cameras, ambient temperature sensors, accelerometers, or any sensor pertinent to expelled or ambient environments. It is also contemplated that a sensor may be external to the device, but connects to a port on one or both of the inner or outer housings.

[0271] In operation, the device may detect a user’s voice or sound via a microphone and reproduce that sound via a speaker. The device may include a microphone, a speaker, a processor, a battery (single use or rechargeable), a charging / data port, communications such as Bluetooth®, volume controls, lights, light-emitting displays (LEDs), a camera, a video screen, measuring ports with the ability to electronically measure breathing (and / or vapor exiting the user’s mouth), noise, speech, tones, etc. The microphone may be noise canceling. The device may provide for communication between the inner and outer elements and any external system by any wired or wireless connection, such as RFID, Wi-Fi, Bluetooth®, Zigbee, Zwave, 2G, 3G, 4G, 5G, or any reasonable later-developed wireless modality.

[0272] The device may also include a feedback unit for the user, such as a headphone or an in-ear component. The feedback unit may assist the user in hearing the user’s voice. The feedback unit may also include an external microphone embedded in the outer element or connected to, but separate from, the outer element. The external speaker may transmit sound to the user’s ear. The feedback unit may be dimensioned and configured to include additional microphones in other locations around the user, such as at the user’s throat. The feedback unit may be useful for masks, helmets, or other item that covers or isolates the user’s head.

[0273] It is contemplated that the device may include any other reasonable technology, system, or processes to assist in communication between a user and another. These technologies include microprocessors, microcontrollers, computer chips, programmable algorithms for processing the data of the device (including sound), any component for capturing sound and human voice, speakers and any technology used to project sound and human voice, noise cancellation technology, wireless capabilities for communication between the microphone and the speaker as well as between the device and remote devices such as external speakers, portable / cellular phones, watches, computers, and televisions. The device may include voice enhancing technology and voice recognition / voice regeneration technology as well as voice command technology as found in personal digital assistants like Amazon® Alexa®. The device may include machine learning and other programming code that will learn the voice of the user and optimize the system for that voice or regenerate voice in that user’s voice. Machine learning or artificial intelligence (Al) may be utilized to create, support, or optimize various functions of the disclosed devices, systems, and methods. For example, machine learning or Al may be utilized to optimize inputs and outputs into or out of communication devices. Al-based voice translation may be implemented on-board communication devices or on a connected mobile computing device or cloud computer. In some embodiments, optimized audio from a speech output profile may be utilized as input for voice translation or Al-based voice translation. It may be particularly advantageous to use optimized audio from a speech output profile for Al voice translation which retains one or more sound characteristics of a user’s speech. For example, Al voice translation may provide for amplitude matching at one or more frequencies of a user speech spectrum, meaning that the amplitudes of the profile- corrected untranslated speech and the translated speech therefrom may be approximately matched at one or more frequencies of the user speech spectrum.

[0274] The wearer’s voice may be translated into the language of a third party by a translation service such as Amazon translate, Google Cloud translation, or Microsoft translator, among others. Alternatively, a communication device may comprise all necessary hardware and / or software to perform voice translation on-board in real-time with minimal delay (i.e., about 0.5 seconds or less to about 5 seconds) between the spoken words and projected translation. An application running on a smartphone may interface with the communication devices and systems in order to change or implement any described settings or features. In further embodiments, other functionalities performed by the communication device itself, an external computing device such as a smartphone or computer, and / or a cloud computer, include voice translation, voice transcription, accent translation, and / or voice recordation. Voice recordation and / or transcription embodiments may interface with a local or cloud storage device to, respectively, save speech audio and / or transcribe spoken words by the user to text. Such embodiments may advantageously be used for medical records or recording any other user speech. This voice may be increased in volume based on settings on the device and voice processing in the unit. This voice might be changed, such as via an electronic voice synthesizer or similar technology. The device may include hardware or software acoustic filters in the device that may screen out nonhuman voice range sounds.

[0275] In yet further embodiments, one or more components may be located in a positive air pressure device (such as a BiPAP or CPAP device fluidly coupled with a respirator mask by a fluid delivery tube). For example, it has been discovered that sound traveling from a respiratory mask to a positive air pressure device through the fluid delivery tube may be captured by a microphone in the positive air pressure device for effective amplification or for other features such as transcription, recordation, translation, etc. as described herein. For example, FIG. 44A depicts a respiratory mask 4400a coupled with a fluid delivery tube 4410a. The fluid delivery tube is shown with a broken line but connects continuously from the mask 4400a to the positive air pressure device 4450a. In the exemplary embodiment, the microphone 4420a is provided in or associated with the positive air pressure device 4450a. For example, the microphone 4420a may be located in the fluid airspace in or near the positive air pressure device 4450a or may be separated from the fluid airspace by a soundtransmitting material such as a filter, membrane, plastic, or other material. The user speech picked up by the microphone 4420a may then be utilized by any other components 4430a including but not limited to analog components, digital components, processors, speaker, wireless networking components, etc. as described herein. For example in an embodiment, the positive air pressure device 4450a may include audio processing capabilities and may then either play back amplified speech from an incorporated speaker, or may transmit amplified speech to another device or speaker. In another embodiment, the positive air pressure device 4450a may transmit the raw or processed voice signal to another device, such as a mobile computing device, for processing / playback. It can be appreciated that the positive air pressure device 4450a may contain any features related to the concept of capturing user speech by a microphone of the positive air pressure device 4450a.

[0276] Alternatively or additionally, one or more microphones (e.g. 4420b and 4420c) may be located on or associated with the respiratory mask as depicted in FIG. 44B. While FIG. 44B shows the positive air pressure device 4450b having no microphone itself, it is contemplated that a further microphone may be present in the positive air pressure device, in addition to one or more microphones associated with the respiratory mask. Where one or more microphones 4420b or 4420c are associated with the respiratory mask or fluid delivery tube coupling portion thereof as taught herein, they may be connected with the positive air pressure device by one or more wires 4425. Alternatively, one or more of the microphones are wirelessly connected with the positive air pressure device 4450b. As with the example of FIG. 44A, the positive air pressure device 4450b may contain any audio components 4430b to process the user speech from the microphone(s) or to transmit raw or processed user speech signals to an external device. It is also contemplated that a positive air pressure device (4450a, 4450b) may include selectable speech output profiles as taught herein. Speech output profiles may take into account the mask material type, manufacturer, and manufacturer model no., and may further take into account aspects of the fluid delivery tube (length, inner diameter, material, manufacturer, and / or manufacturer model no.) and positive air pressure device (model, positive air pressure device settings, etc.). Therefore, as taught herein, contemplated are various positive air pressure ventilation systems including speech amplification by one or more microphones of a respiratory mask and / or positive air pressure device. In yet further embodiments, one or more microphones may be placed along or attached to an exterior of a fluid delivery tube at a position between the respiratory mask and the positive air pressure device.
