Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This international application claims priority to U.S. Provisional Application No. 63 / 425,167, filed on November 14, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present 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 health concerns often require the use of such coverings and / or masks to protect the wearer from outside air, liquids, particles, pathogens, or other harmful substances. While masks and hoods can protect the wearer, they can also reduce or muffle the wearer's voice, thereby hindering communication. The present disclosure provides modular communication devices that can be attached to and interfaced with a disposable or reusable mask or hood and allow the user's voice to be amplified externally on the mask or hood for use in communicating with a third party. The present disclosure also provides systems and devices for capturing the voice of a respirator, mask, or hood wearer at the respirator or within a fluid delivery tube, and replaying or amplifying the wearer's voice for use in communicating with a third party. The communication devices and related systems and methods can advantageously include an audio output profile to compensate for voice transmission losses through the mask, mask, respirator, or hood. Sound output profiles and additional features including speech transcription and / or recording may be included in or by such communication devices, connected mobile computing device applications, or Internet-connected servers / clouds.

DETAILED DESCRIPTION

[0271] The details of one or more embodiments of the present invention are set forth in the accompanying description below. Although any materials and methods similar or equivalent to the materials and methods described herein can be used in the practice or testing of the present invention, preferred materials and methods are now described. Other features, objects and advantages of the present invention will become apparent from the description. In the description, the singular also includes the plural, unless the context clearly dictates otherwise. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the invention belongs. In the event of a conflict, this description will control.

[0272] As described above, in some embodiments, the present disclosure relates to a patient breathing mask including a microphone disposed thereon, the microphone being configured to interface with a wired or wireless speaker and / or a wired or wireless communication device (e.g., a telephone). In some embodiments, the present disclosure relates to a modular communication device for use with mouth, nose, face, and head coverings, including masks. The present disclosure provides a modular communication device that can be attached to a disposable or reusable mask or face shield and allows the user's voice to be amplified on the outside of the mask. Although the following is described with reference to various exemplary embodiments, the present disclosure is not limited thereto.

[0273] In some exemplary embodiments, the microphone is a noise-canceling microphone. In yet another embodiment, the microphone includes or is associated with at least one noise filter. In yet another exemplary embodiment, one or more of the microphone, speaker, and communication device are wireless. It should be understood that reference to components such as microphones, speakers, etc. as being wireless or transmitting wirelessly encompasses configurations in which such devices are connected to components including wireless transmitters and / or receivers. Therefore, any reference herein to "wireless" components should be interpreted to encompass such configurations. In yet another exemplary embodiment, an onboard speaker is integrated into a portion of the respiratory mask. In yet another exemplary embodiment, the speaker is external to the mask.

[0274] As already noted, in exemplary embodiments, the patient respiratory mask includes an internal, and / or coupler-adapted or tube-adapted, noise-canceling microphone with wireless (e.g., Bluetooth®) capabilities. In exemplary embodiments, the microphone is attached to or built into the respiratory mask, a coupler designed to attach to the mask tube interface, or the mask fluid delivery tube (e.g., for oxygen, air, or some other gas). In additional exemplary embodiments, the coupler includes one or more of the microphone, speaker, wiring, processor, and communication device. In exemplary embodiments, one or more of the aforementioned elements is embedded in or provided by a portion of the coupler.

[0275] As discussed above, in yet another exemplary embodiment, the microphone wirelessly transmits the patient's voice via Bluetooth® technology to a Bluetooth® speaker that is in proximity to and in communication with a Bluetooth® transmitter. References herein to a "Bluetooth®" device refer to a device capable of using Bluetooth® technology. In yet another exemplary embodiment, the microphone wirelessly transmits the patient's voice via Bluetooth® technology to a Bluetooth® smartphone that is 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, other Bluetooth® communication devices are also contemplated by this disclosure.

[0276] Now refer to Figure 1 An exemplary patient respiratory mask according to the present disclosure includes an exemplary microphone disposed therein. In the exemplary embodiment, the respiratory mask is a CPAP (or BIPAP) respiratory mask (generally shown at 10) having a mask portion 12 and a Bluetooth® microphone 14 incorporated into a fluid air space (generally shown at 16) of the mask 10 near the patient's mouth (not shown). The exemplary mask also includes a fluid delivery tube 18 and at least one mask inlet 20.

[0277] In an exemplary embodiment, microphone 14 is mounted on or disposed within the material of the mask. In another exemplary embodiment, the microphone is disposed in a separate microphone tube (not shown) that can extend at least partially into the fluid air space of mask 10. For example, the microphone tube can be formed as part of a coupler or inserted into the mask or coupler. The microphone tube is typically positioned within or adjacent to the interior air space of the mask, coupler, or fluid delivery tube. In some embodiments, the microphone tube is removably inserted into a port or opening on a respirator, mouthpiece, PAPR hood, or the like. The microphone tube typically has a tubular structure that contains a microphone disposed within the tube, such that the tube collects sound to be picked up by the microphone. In yet another exemplary embodiment, the microphone tube is at least partially sealed, for example, by a plastic or membrane that is at least moderately transparent to sound but also independently maintains the integrity of the fluid air space 16 within respirator 10.

[0278] Such an exemplary microphone tube can be disposed within or mounted to the respiratory mask 10, the fluid delivery tube 18, or any coupler 22, or a portion intermediate the fluid delivery tube 18 and the respiratory mask 10.

[0279] Now refer to Figure 2 , another exemplary patient respiratory mask 10 incorporates such a Bluetooth® microphone 14 into a coupler device 22 positioned between the fluid delivery tube 18 and the respiratory mask 10. In the exemplary embodiment, the coupler 22 is sized and configured to provide a friction fit to the mask inlet 20 on one side and to the fluid delivery tube 18 on the other side. Figure 3 , the exemplary coupler 22 includes a mask inlet side (generally shown at 32), a fluid supply tube side (generally shown at 34), wherein the main air flow traverses the interior of the tube (generally shown at arrow 36).

[0280] In an exemplary embodiment, microphone 14 is separated from the body airflow 36 by a filter 38, which can be configured to filter one or more sound characteristics or simply isolate the microphone from the body airflow. Filter 38 can be a membrane, an acoustic mesh, or any other convenient sound-transmitting material.

[0281] In the exemplary embodiment shown, the microphone is shown as being operably connected to a microphone preamplifier 40, an equalization component 42 (e.g., an analog-to-digital converter (ADC) and a digital signal processor (DSP)), a Bluetooth® transmitter 44, sound output components (e.g., a digital-to-analog converter (DAC), an amplifier (Amp), and a speaker 45), an antenna 46, and a power source 47 (e.g., a battery or a wired power adapter). These components are shown in the exemplary embodiment as both connected to the microphone and housed on a protruding portion 48 of the coupler 22. However, it should be appreciated that the microphone can be configured onboard the coupler 22 with more or fewer associated components, with some components or processes omitted or performed elsewhere (e.g., external to the coupler 22, remote from the coupler 22, etc.).

[0282] Additionally, the coupler may take any convenient shape while accommodating such components, so long as the connecting portions 32 and 34 are configured to connect to the mask inlet 20 and the fluid delivery tube 18, respectively.

[0283] In an exemplary embodiment, the coupler can be configured to attach to the fluid delivery tubing regardless of any variations in tubing diameter (e.g., configuration differences allow for use with 19 mm inner diameter standard tubing versus 15 mm inner diameter narrow tubing). Thus, exemplary embodiments provide a universal attachment (e.g., a clip, as shown in FIG. 4 , etc.) configured to fit a wide variety of tubing and respiratory devices.

[0284] In yet another exemplary embodiment, the microphone or other electronic components are configured to be externally attached (e.g., as a clip-on attachment, etc.) to the respiratory mask 10, but in close proximity to the patient's fluid air space (see Figure 1 16 in ). Now refer to Figure 4A , a clip 50 is shown with the microphone unit 14 disposed on the underside of the clip. In the exemplary embodiment, the clip 50 is also connected to the power and signal line 54 interface via the port 56. Although such a clip can be configured to be attached to any location that is convenient for placing the microphone unit 14 near a sound transmission surface (e.g., the inlet portion 20 of the mask 10 or the outer portion of the coupler 22), FIG4 shows the clip 50 disposed on a portion of the fluid delivery hose 18, wherein the microphone unit abuts or is close to the material of the hose to pick up sound vibrations transmitted through the hose. It should be appreciated that while FIG4 shows a wired configuration, the microphone unit can also be configured with a battery and a wireless (e.g., Bluetooth®) transmitter. Figure 4B An exemplary side view of the clip 50 is shown with the microphone 14 positioned proximate the tube 18 in the installed position.

[0285] Now refer to Figure 5, the fluid delivery tube 18 is shown to include an integrated coupler 22 containing the microphone 14 therein (see Figure 2 ) and can be attached to or integrated into respiratory fluid delivery tube 18. An exemplary power cable 24 runs along at least a portion of tube 18 to microphone 14 (which can be configured as a wired or wireless (e.g., Bluetooth®) arrangement). As noted above, the coupler can also include other components such as processing or filtering components, wireless transmitters, etc. in addition to or as an alternative to a microphone (e.g., speaker), wiring, or any other type of communication device.

[0286] In yet another embodiment, microphone 14 can be configured as a wired microphone utilizing exemplary cable 24 or other cable for data transmission. In additional exemplary embodiments, the microphone can be wireless and can be connected to a battery power source without having a cable run along a portion of tube 18.

[0287] In yet another embodiment, the cable may be configured with one or more clips to secure it to the hose 18 or as an integral part of the hose 18, such as embedded in or permanently attached to the tube 18 or a conduit harness. Figure 6 Attaching the cable 24 to the tube 18 is shown in FIG. In an exemplary embodiment, the cable 24 is configured as a harness secured at one or more locations via a harness clamp 62, wherein the cable can be connected to the coupler 22 (e.g., Figure 2 and Figure 3 as shown) or masks (as Figure 1 As with any wired configuration, the far end of the cable 24 (away from the mask) can be configured to connect to additional components such as speakers, processors, networks, power supplies, etc.

[0288] The apparatus of the present invention may comprise several components. Figure 11 is a block diagram illustrating various components of an embodiment of the present invention. In this embodiment, a microphone, microphone amplifier, digital signal processor, speaker amplifier, and speaker are shown. Also present are a battery, battery management, voltage regulator, and USB. Other embodiments and configurations may be utilized.

[0289] Figure 12 An alternative embodiment of the device of the present invention is shown, which can be worn by a mask user (such as Figure 13 A flat connecting flexible cable with a microphone module and a speaker module (as shown). The microphone module portion is designed to engage with a mask clip that can be magnetically engaged for attachment to the mask in between.

[0290] The device of the present invention can be attached to the front [exterior] of the mask. Figure 14Is a perspective view of the device attached to the outside [front] of the mask. The housing of the device is shown, and the mask clip [not shown] will be positioned on the inside of the mask to engage with the housing.

[0292] Figure 16 This is an illustration of the device showing the exterior front of the mask in use.

[0293] When in use, the device is relatively small and lightweight (eg, no more than about 25 grams, and no more than about 17 grams). Figure 17 is a photograph showing an embodiment of the device clipped onto the exterior front of the mask.

[0294] The compact nature of the device makes it ideal for long-term use. Figure 18 1 is a diagram of an embodiment of a device indicating a speaker. Not shown are the microphone on the back of the device and the internal Bluetooth device. Figure 19 shown Figure 18 A further exploded view of an embodiment of the device depicts the housing and a mask clip with a hanging loop [also known as a pull ring].

[0295] The components of the device fit neatly and compactly into a housing designed to engage with a mask clip. Figure 20 . In this embodiment, both the housing and the mask clip are shown as having magnets. However, in other embodiments, a single magnet may be employed to attract and couple with a ferromagnetic or ferrimagnetic component. Yet another embodiment of the present invention is an "L-shaped" device having an "L-shaped" housing and a corresponding "L-shaped" mask clip that are designed to engage with each other to attach the device to a mask.

In other embodiments, multiple Bluetooth® devices can be connected simultaneously via a variety of connections or modes.

[0308] It will be apparent to those skilled in the art that, although embodiments have been shown and described, various modifications and variations may be made to the invention disclosed herein without departing from the spirit or scope of the invention. Furthermore, the exemplary embodiments described above are to be interpreted in a non-limiting manner both in construction and method. Accordingly, it should be understood that the various embodiments have been described by way of illustration and not limitation.

[0309] In embodiments, the device may be a communication device sized and configured for use with a mask, or other device intended to cover a user's face, nose, mouth, and / or head. Commonly used facial masks can muffle and suppress a user's speech, making communication more difficult. Wearing a mask can reduce the inherent effectiveness of a mask by requiring the wearer to stand closer, shout louder, or remove the mask to adequately communicate. The disclosed communication device, when combined with a mask, allows a disposable or reusable mask to improve communication for a user at a safe distance and while using a phone or other communication device.

[0310] The mask can be made of cloth, paper, cardboard, plastic or other materials. The mask can be used to hide the user's identity and prevent the user's breathing or expelled gases, liquids or particles from spreading. The mask can also protect the user from inhaling or coming into contact with other gases, liquids or other particles on the face. The example of a mask includes those items selected from the group consisting of the following: cloth masks, fabric masks, disposable masks, single-use masks, surgical masks, surgical masks, medical masks, plastic masks, dust masks, filter masks, respirator masks, breathing masks, oxygen masks, KN95 masks, N95 masks, surgical N95 masks, N99 masks, KN99 masks, N100 masks, KN100 masks, R95 masks, P95 masks, P100 masks, PM2.5 masks, FFP1 masks, FFP2 masks, FFP3 masks, CPAP masks, BiPAP masks, multi-layer masks, masks with removable filters, face masks, handkerchiefs, headscarves, veils, protective hoods, face towels, masks with assemblers, masks with brackets, and combinations and layered arrangements thereof.

[0311] The communication device can be removably attached to a disposable or reusable mask, which is particularly useful for medical professionals, patients, first responders, or anyone who desires to cover their nose and mouth and / or filter the air they breathe or exhale. The communication device can be reusable so that it can be removed from a first mask to a subsequent mask. In an embodiment, the communication device can be modular, having multiple parts that allow it to be attached to a mask. The communication device can include an inner housing and an outer housing, or only one inner housing or one outer housing. The communication device can be autoclavable, sterilizable, or disposable.

[0312] The inner and outer housings of the communication device can each include all other necessary components for the successful operation of the communication device. The housings can be constructed of any reasonable material used in commercial, personal, or medical devices (e.g., plastic, metal, wood, or man-made or natural materials). Each housing can also include elements for securing the inner and outer housings to the mask and establishing a connection between the inner and outer housings. To connect the inner and outer housings to the mask, the inner and outer housings can include mechanical clips, springs, magnets, pins, hooks and loops, snaps, buttons, glue or other adhesives, zippers, sutures, cords, ties, staples, suction cups, or other connection devices. Certain features (e.g., snaps, buttons, zippers) can complement features on the mask. The housings can be configured to slide into and be placed in a pocket or other device for securing to the mask. The inner and outer housings can be configured to attach to glasses, hats, or other wearable items, allowing the inner housing to be placed in close proximity to the user's mouth or nose.

[0313] The inner and outer shells can each include complementary magnetic attachments that allow the inner and outer shells to be attached to each other and separated through the mask. The magnetic attachments can create a secure and removable connection on the mask. The magnetic attachments can be rings on each shell that create a secure connection between the inner and outer shells and securely attach the communication device to the mask. The complementary magnetic attachments mate with each other across the mask but still allow electrical signals to pass between the inner and outer shells. The complementary magnetic attachments can be rings, squares, or any other shape with an open center. The complementary magnetic attachments can also be multiple complementary magnetic attachments on each of the inner and outer shells. The complementary magnetic attachments can have the ability to attach a designed or otherwise displayed message to the outer shell as a form of free speech or advertising.

[0314] The inner and outer elements can be sized and designed with curved shapes that complement each other. The curved shape of the inner element can be placed inside the mask, extending from side to side across the area in front of the user's mouth. The speaker can be located in a central position between the two sides so that it is close to the user's mouth. Other features of the inner element (e.g., electrical and attachment features) can be positioned along the curved shape of the microphone side. The curved outer element can be attached to the inner element via magnetic attachments at positions that complement the inner element. In other embodiments, these elements can be part of or attached to an internal support frame / bracket that supports the shape of the mask on the user's face.

[0315] The inner and outer housings can contain a power source. The power source can be in both housings, or in only one of the housings. The power source can be a replaceable or rechargeable battery. Due to the close proximity of the housings, power can flow through the mask from the powered housing to the non-powered housing via induction or other modalities. Alternatively, as described above, a physical connection can span between the inner and outer elements to provide power to the non-powered element or exchange data between the elements. It is also contemplated that the device can be used with masks that have existing ports (for air flow, etc.), thereby allowing a suitable path for the physical connection between the inner and outer elements.

[0316] One or both of the inner and outer housings may include ports and / or cables for power or charging or for data transfer. The ports and / or cables may connect the housing, components, and device to another system for data or signal processing, charging, external speakers, or communications, or any other related system.

[0317] The internal element can be located inside the mask, close to the user's mouth, to easily pick up the user's voice. The internal element can function as or include both a microphone and a transmitter. The internal element can transmit signals representing the user's voice to the external element. The external element can be removably attached to the outside of the mask. The external element can include a transmitter, a receiver, and a speaker to receive signals from the internal element and then project the user's voice. The user's voice can be projected via a speaker in the external housing, or the internal or external housing can also transmit the voice signal to an external speaker or system. The speaker in the external housing can be used together with or in conjunction with the external speaker or system to project the user's voice. The microphone, speaker, and electrical processing can include any of the elements described above. The speaker can include a horn-shaped housing (e.g., a loudspeaker) to amplify the user's voice. Signal transmission between the internal and external elements can be wireless or via a physical connection between the elements. Wireless transmission between the internal and external elements is suitable for reusable or disposable masks. Transmitting electrical signals via a physical connection can include an element extending from the internal or external element, which penetrates the disposable mask and establishes a physical and electrical connection with the other element. The connection is suitable for disposable masks or can be used with reusable masks.

[0318] In the communication devices and systems herein, masks, protective hoods or other face masks can have various built-in aspects for engaging or interfacing with communication devices and systems. The mask, protective hood or face mask can have a built-in magnet or metal magnetic attachment with which the magnetic portion of the communication device can be detachably engaged. The built-in magnet or magnetic attachment may not require an internal housing, a mask clip, or any other parts inside the mask. Alternatively, a magnet or metal can also be inserted into the mask. For example, the mask can include a gap for inserting a magnet or metal, or a standard disposable mask or a multi-layer reusable mask can be cut open by a knife to insert a magnet or metal, and then the gap is sealed with tape. It is understood that any method of incorporating a magnet or metal into a facial mask or protective hood is contemplated.

[0319] In alternative embodiments, the microphone can be built into the mask, or can be built into any other face mask or protective head covering as a single-use device. For example, the microphone can be embedded in a disposable facial mask and can have a wiring connector extending from the mask for connecting to a speaker or interface device. Alternatively, the microphone embedded in the mask can be wireless. In another embodiment, the microphone embedded in the mask can be wireless and disposable, or wireless and rechargeable. In another embodiment, the microphone can be waterproof and the mask can be reusable, washable, and / or sterilizable. Alternatively, the microphone can be inserted into the mask. For example, the mask can contain a slit for inserting the microphone, or a standard disposable mask can be cut open with a knife to insert the microphone and then the slit can be sealed with tape. It will be understood that any manner of incorporating the microphone into the facial mask or protective head covering is contemplated.

[0320] In an embodiment, the mask or protective head cover may include a built-in sound waveguide (e.g., a sound transmission pad). Such a sound waveguide optimizes the collection of sound within the mask or protective head cover and routes it to an attachment area coupled to the waveguide, to which a portion of the communication device is connected to pick up the sound. The connection between the communication device and the attachment area can be a connector, an adhesive, a magnet, or any other suitable connection. The attachment can be a physical connection that places a microphone or piezoelectric pickup near the attachment area and / or the waveguide. Optionally, the mask or protective head cover may include a microphone or piezoelectric pickup coupled to the waveguide, and the communication device may be electrically connected to the microphone or piezoelectric pickup interface.

[0321] Alternatively, the mask or protective hood may include clips, pockets, slots, or other features that complement the housing of the communication device so that the device can interface with the mask or protective hood. In an embodiment, the communication device may include a first housing (e.g., Figure 12 and Figure 13 ), wherein the first housing is configured to interface with a built-in portion of a mask or headgear, rather than including a magnetic attachment. Typically, such a built-in connector positions the microphone substantially facing the mouth of the mask wearer to pick up speech from the wearer.

[0322] In yet another alternative embodiment, the mask or protective headgear can include all the components required to pick up and amplify the wearer's voice. For example, the mask or protective headgear can include a microphone, a speaker, a power supply, and any analog or digital circuitry required to project the user's voice from the speaker. One or more of these components can be permanently or removably incorporated into the mask or protective headgear, with the remaining components arranged within one or more housings of the communication device. As described herein, one or more housings of the communication device can be removably attached to the mask or protective headgear.

[0323] The embodiments disclosed herein are generally used for protective hoods such as PAPR protective hoods. A "PAPR protective hood" is a portion of a powered air purifying respirator that a user can wear to protect against environmental or biological hazards. Such a protective hood typically surrounds the wearer's head or head and neck and is connected to an external source of filtered positive pressure (e.g., a battery-powered positive pressure source). PAPR protective hoods are typically equipped with flexible or semi-rigid transparent plastic windows so that the wearer can see through and so that the wearer's face can be seen from the outside. The term "PAPR protective hood" or more generally "protective hood" is intended to encompass any protective hood, respirator, or similar safety or medical device that covers the user's head or face to provide filtered or positive pressure air to the user. For example, it is contemplated that the communication device herein is used with a PAPR protective hood, respirator, and any other type of protective hood.

[0324] The embodiments herein may be attached to such protective hoods using mechanical clips, springs, magnets, pins, hooks and loops, snaps, buttons, glue or other adhesives, zippers, sutures, strings, straps, staples, suction cups, or other connecting devices. Certain features (e.g., snaps, buttons, zippers) may complement features on the protective hood. The magnetic attachments disclosed herein are generally used to removably attach a housing to a transparent window of a PAPR protective hood. Various "attachment portions" are contemplated for engaging with a portion of a communication device.

[0325] While any of the described communication device configurations are contemplated, in some embodiments, a first housing having a microphone is provided with a wired or wireless connection to a second housing having a speaker (see, e.g., Figure 12 and Figure 13 In some embodiments, the first housing including the microphone is removably attached to the mask or protective hood. In some embodiments, the first housing including the microphone is removably attached to a transparent window of the PAPR protective hood. In some embodiments, the second housing with the speaker may include a mechanical clip, spring, magnet, pin, hook and loop, snap, button, glue or other adhesive, zipper, suture, string, strap, staple, suction cup, or other connecting device for engaging with an item worn on a person.

[0326] In some embodiments, the first housing having one or more of the microphone and / or speaker can be removably attached to the mask or protective hood via a snap connector attachment portion. The snap connector typically has a circular protrusion that can engage with a complementary recess. In an exemplary embodiment, the protective hood or mask can include a protrusion or recess of a snap connector that can engage with a complementary protrusion or recess on the device housing (e.g., the first housing including the microphone). The protrusion or recess on the protective hood or mask can be permanently attached, built-in, or removably attached. The protrusion or recess can be attached to an adhesive pad. Such an adhesive snap connector attachment portion can be bonded to the mask or protective hood (e.g., to a transparent window of a PAPR protective hood). Figure 27 An example of a male post with an adhesive pad and a female connector complementary to the male post is shown. In some embodiments, a communication system includes a mask or PAPR head cover having a built-in or removably secured connector (i.e., an attachment portion), and a communication device including one or more housings, one of which has a connector complementary to the connector on the mask or PAPR head cover.

[0327] In some embodiments, the mask or PAPR protective head cover includes a built-in magnetic attachment portion. For example, the mask or PAPR protective head cover can include a magnet, a ferromagnetic material (e.g., metal or iron), or a ferrimagnetic material. For simplicity, the term "metal" will be used to refer to a ferromagnetic or ferrimagnetic material that can engage with a magnet. The mask or PAPR protective head cover can have a permanently attached, embedded, or bonded magnet or metal attachment portion that is complementary to the magnet or metal on the housing of the communication device. In some embodiments, the communication device can have a first housing including a microphone, the housing having a magnet disposed on an outer surface that is complementary to the magnet or metal attachment portion associated with the mask or PAPR protective head cover.

[0328] For example, Figure 28 As shown, the PAPR protective head cover may include an embedded, attached, or bonded portion for removably engaging with a portion of a communication device. Similarly, any other type of mask may include an embedded, attached, or bonded portion for removably engaging with a portion of a communication device. Figure 28 The outlined portion in FIG is shown at a particular location on the PAPR protective head cover window, but it will be understood that any bonded or otherwise attached portion can be located at any useful location (typically placing the microphone close to the user's mouth).

[0329] In some embodiments, a magnet or metal complementary to a magnet can be adhesively attached to the interior of a mask or PAPR hood window as an adhesive attachment portion. Figure 29An exemplary embodiment of an adhesive attachment portion containing or embedded with metal or a magnet is shown. The adhesive portion typically comprises a flexible support member coated with an adhesive on one side. The metal or magnet is typically located on a surface of the adhesive side or embedded within the adhesive portion. The metal or magnet is optionally coated with an adhesive. The adhesive portion can be a disposable, optionally sterile portion for bonding to the interior of a PAPR protective hood window. Advantageously, the adhesive portion can be placed anywhere on the interior of the PAPR window so that a magnetic (or alternatively metal-containing) portion of the communication device can removably engage 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 does not loosen or fall off within the PAPR protective hood or mask during use or if the communication device is removed.

[0330] In an embodiment, the system includes a PAPR protective head cover, 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 the communication device is a complementary annular metal or magnet surrounding a microphone or microphone hole in a housing of the communication device. In an embodiment, the PAPR protective head cover may include a sound transmission surface for attachment of the communication device. The sound transmission surface may be the PAPR protective head cover window, a separate portion of the protective head cover, or a portion of the PAPR protective head cover window that has the same or different material as the rest of the PAPR protective head cover window. In an alternative embodiment, the metal or magnet is directly coated with an adhesive for fixing to the inner surface of the PAPR protective head cover window.

[0331] In an alternative embodiment, the communication device is secured to the other (exterior) face of the PAPR hood window by screws or bolts, with a nut fastener on the other side. The nut fastener or the communication device may include 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 maintain an airtight seal around the hole in the PAPR hood window. Alternatively, a bracket may be secured to the PAPR hood window with screws, allowing the housing of the communication device to dock against the PAPR hood window (e.g., a microphone housing). Alternatively, the bracket or docking connector may be formed as part of the PAPR hood or PAPR hood window to allow the housing to dock in the use position.

[0332] Figure 30An exemplary embodiment of a microphone portion of a communication device that is removably attached to a window of a PAPR protective head cover is depicted. As disclosed herein, the microphone portion is typically a microphone contained within a housing and configured to pick up a user's voice through a mask or PAPR protective head cover. In the depicted embodiment, a first housing that is removably attached to the window of the PAPR protective head cover contains at least the microphone, and the first housing is connected, either wired or wirelessly, to a second housing that contains at least a speaker. As disclosed herein, the microphone and speaker are operably connected. In an alternative embodiment, both the microphone and speaker can be removably attached to the PAPR protective head cover window, with the microphone and speaker contained within the same or separate housings.

[0333] Other attachment types are contemplated, for example, attachments that do not require a separate attachment portion on the mask or protective head cover to engage with the housing of the communication device. In an embodiment, the microphone can be disposed in a housing configured to adhesively attach to the outer surface of the PAPR protective head cover window. Figure 31 Embodiments are described having a microphone housing including a flange for engaging an adhesive portion. In some embodiments, the adhesive portion includes a snap ring and a double-sided adhesive pad. In some embodiments, the double-sided adhesive pad is a gel material, a paper material, a foam material, or any suitable material that supports an adhesive surface. In embodiments, the snap ring has a tab or ring on its periphery that allows the device to be removed from the PAPR protective head cover after it has been adhered. In embodiments, the snap ring and gel pad are disposable. Figure 32 A rear view of an exemplary embodiment is depicted.

[0334] In some embodiments, some PAPR protective head covers can cover the user's head and make it difficult for the wearer to hear third parties. In such embodiments, it may be advantageous for the communication device and system to include a second speaker placed inside the PAPR protective head cover. Figure 33 An exemplary embodiment is depicted having a communication device operably connected to an additional speaker located within the PAPR protective headcover (shown as attached to the interior of the viewing window, but may be positioned anywhere within the PAPR protective headcover). Figure 33The device depicts a microphone housing connected to a speaker housing having a microphone for picking up a user's voice outside the PAPR protective headgear window. The speaker housing includes a speaker and analog and / or digital audio processing circuitry to project and amplify the user's voice. The speaker housing can include an additional microphone for picking up voice from outside the PAPR protective headgear (e.g., voice from a third party). Voice from the additional microphone can be projected through a speaker located inside the PAPR protective headgear, allowing the user to clearly hear the third party's voice. In an alternative embodiment, a single unit is placed inside the PAPR protective headgear, containing both the microphone for picking up the user's voice and the speaker for playing back the third party's voice (picked up by a second microphone outside the headgear). In yet another alternative embodiment, two units are placed inside the PAPR protective headgear: one unit containing the microphone for picking up the user's voice and the other unit containing the speaker for playing back the third party's voice (picked up by the second microphone outside the headgear).

[0335] In another embodiment, a communication device housing can be removably attached to a mask (e.g., a disposable facial mask) using hook and loop attachments. In an embodiment, the hook and loop attachments are associated with the housing of the communication device (e.g., a microphone housing), and the hook attachments are configured to engage with an outer surface of the disposable facial mask. Alternatively, the facial mask or PAPR protective head cover may include an annular surface for hook and loop connections, or may include a generally rough and fibrous surface for attachment of hook and loop connectors. Other types of related removable connectors are contemplated, including any connector having an array of protrusions that interfere when mated with a connector (e.g., any Velcro-type connector known in the art).

[0336] In some embodiments, a microphone module associated with a user's mask or PAPR headgear communicates wirelessly with a speaker module and / or with a user's computing device (e.g., a computer, tablet, mobile smartphone, or other module with communication capabilities). Generally, any communication protocol, including RF, Wi-Fi, Bluetooth, 5G, other cellular protocols, etc., is useful. In embodiments, the microphone module can be docked into the speaker module for storage and / or charging. In embodiments, the microphone module and the speaker module, either individually or together, are docked into another module that supports storage, charging, and / or disinfection of one or more communication devices.

[0337] In an embodiment, a docking station is provided for any of the communication devices described herein. Figure 34 and Figure 35An exemplary docking station is depicted. In the depicted embodiment, the speaker housing (or speaker module) has a clip for attaching to a respirator hose (e.g., fluid delivery tubing, respirator hose, PAPR hood tube, etc.). The docking station may include multiple posts for engaging with the speaker housing's clips or other connectors. In the engaged position, the speaker housing can be charged via a wired or wireless charging connection. In embodiments, the docking station includes approximately 1 to 20 posts, or approximately 1 to 10 posts, or approximately 2 to 9 posts. In some embodiments, the docking station includes 2 posts. In some embodiments, the docking station includes 5 posts. The docking station may also provide UV disinfection capabilities. The docking station base and posts may be UV transparent, allowing UV light generated within the unit to illuminate substantially all surfaces of the speaker housing. Advantageously, these posts also contain UV light to illuminate and irradiate the back of the module and clip to ensure adequate disinfection. In embodiments, the microphone housing and wiring (or alternatively, the microphone module in wireless embodiments) may also remain within the docking station. In another embodiment, the microphone housing and wiring may be removed prior to docking.

[0338] The disinfecting UV light (typically UV-C) can be generated by any suitable light source, including light-emitting diodes (LEDs), fluorescent lamps, or other UV-C light sources. Typically, the UV sterilizer also includes a UV-blocking cover or hood with a reflective inner surface to reflect the disinfecting UV light onto the contained modules. With the cover covering the unit, the disinfecting UV-C is contained within the unit and, for user safety, is substantially not emitted outside the unit. In embodiments, the UV sterilizer includes a safety feature, such as a button or interlock, which prevents the UV sterilizer from emitting UV-C until the cover is in place. In embodiments, the UV-C sterilizer also includes wireless capability for interfacing with a user's mobile device, computer, or smartphone to control one or more functions of the sterilizer or schedule a disinfection run. In embodiments, the sterilizer includes a timer, sensor, or combination thereof to set an appropriate run time for disinfecting the contained equipment.

[0339] In some embodiments, the speaker housing has an alternative mechanism (e.g., a pocket clip attachment, a magnetic attachment, a snap or button attachment, etc.). The docking station can be configured to accept the shape and configuration of the speaker housing to store, charge, and / or sterilize / disinfect the housing. In embodiments, the docking station can include a wired charging connection (e.g., micro USB, USB-C, Lighting), or other charging interface (e.g., a spring contact interface). In embodiments, such a docking station has multiple docking features that partially or substantially surround the shape of the speaker housing to securely position the housing for charging. In embodiments, the docking features and base of the docking station are UV transparent to allow UV light generated inside the station to pass through.

[0340] The UV disinfection station can have a cover that is merely reflective, or the cover can further include an LED or other UV-C light source for irradiating the contained equipment with disinfecting UV-C light. In an embodiment, the cover is detachable from the disinfection station. In another embodiment, the cover can be hingedly attached to the disinfection station. In an embodiment, power can be supplied to the UV-C light source (if any) in the protective hood via wiring passing through the hinge or via contacts (e.g., spring contacts or other electrical contacts) that connect only in the closed position. In an embodiment, the contacts can serve both to power the cover UV-C light source and to act as an interlock, whereby when the contacts are engaged, the UV-C light will not be powered unless the cover is in the closed position.

[0341] Medical professional clothing can be further designed to accept speaker housings during use. For example, medical scrubs often have slip pockets, but these are large and can sag if an electronic unit is inserted. This creates a risk that the unit may fall out of the slip pocket while the medical professional is caring for a patient. For example, a scrub top can be designed with slip pockets that are configured to securely clamp the speaker unit to the user's torso. The slip pockets can typically be located on the chest area of ​​the user and can also have zippers, snaps, buttons, or Velcro to hold the slip pockets in a closed position when the speaker unit is contained. In some embodiments, the slip pockets are compatible with wired devices and contain channels for wiring that connects the speaker housing to the microphone housing. The slip pockets are typically constructed of the same material as the clothing and can have one or more perforations or acoustic panels to enhance the projection of the user's voice. In yet another embodiment, the speaker module can take other forms that are useful or desirable in a medical environment. For example, medical professionals must wear identification when providing care in a hospital environment. The ID speaker module can be configured to also clamp an identification card required of the medical professional. In an exemplary embodiment, as Figure 36As shown, the ID speaker module can have a transparent front panel that allows the display of an identification card. The front panel can be removed from the device to allow the placement of an ID card, or it can be fixed in place and the ID inserted through a slot on the side or bottom of the device. Typically, one or more speakers will face the same direction as the ID card. One or more speakers can be housed within the ID speaker module and can project sound through perforations on the front of the device. In an embodiment, the ID speaker module also includes a transparent back panel for displaying additional identification or barcodes for accessing medications or consumables. In another embodiment, the ID speaker module can be clipped onto a ring or include a clip for attachment to a medical professional's surgical gown or clothing. The ID speaker module can be connected to an external microphone and / or speaker interface via a wired and / or wireless connection. In an embodiment, the ID speaker module can be connected to other external devices such as a medical monitoring device or a nurse call light, and the module can be equipped with a vibration function or configured to play a sound when the medical professional wearing the device should respond or react to a situation.

[0342] Communication devices and systems are generally used for methods of communication between a wearer and one or more third parties. In some embodiments, a method of communication for a wearer of a mask or protective head covering (e.g., a flexible facial mask or PAPR head covering) may include: attaching a magnetically and removably attachable communication device to the mask or head covering worn by the wearer, the communication device comprising a housing having a microphone, an attachment or attachment portion, and a speaker, the microphone configured to receive speech from the wearer as a voice signal, the attachment or attachment portion being used to secure the housing to the mask or head covering, the speaker operably connected to the microphone and configured to project the voice signal received by the microphone, transmit the voice signal to the speaker, and project the voice signal through the speaker. In some embodiments, the attachment portion is magnetic. In some embodiments, the device comprises a first magnetic attachment component and a second magnetic attachment component, wherein the first magnetic attachment component is associated with a back surface of the housing, and a complementary second magnetic attachment component is arranged to generate an attractive force against the first magnetic attachment component to removably attach the back surface of the housing to the mask. It will be appreciated that any of the described communication devices or systems may be used for methods of communication between a wearer and a third party. Such methods may include advantageously amplifying or conditioning the wearer's voice to improve communication quality.

[0343] Figure 37An exemplary embodiment of a protective hood is shown, which has a microphone that is detachably or permanently attached to the protective hood. In operation, the respirator or powered air filter connected to the protective hood via a supply tube is loud and may make it difficult for a third party to hear the voice from the user. The microphone is positioned and configured to pick up the voice from the user and project the voice from a speaker module or communication device / system. In an alternative embodiment, the microphone can be placed in a coupler between the protective hood and the supply tube, or can be placed at any position along the supply tube. In another embodiment, the respirator or powered air filter at the other end of the protective hood supply tube can have a built-in microphone for picking up the voice from the user. Advantageously, it has been found that the user's voice can be well transmitted along the respirator protective hood supply tube to be captured in the tube or in the respirator unit. The voice picked up in the protective hood or mask, tube and / or respirator unit can then be projected from any interface or external speaker described herein.

[0344] Figure 38 A communication device (e.g., as shown) for use with a respiratory mask (e.g., an NIV mask, a CPAP mask, a BiPAP mask, etc.) is shown. Figure 35 Such a device may include a spring clip configured and dimensioned to surround at least a portion of a fluid delivery tube or coupler to a respiratory mask. The spring clip may advantageously position the sound transmitting portion of the communication device housing in close proximity to the fluid delivery tube or coupler so that the user's voice is transmitted through the fluid delivery tube or coupler and through the sound transmitting portion of the device housing to a microphone disposed on a back portion of the housing. In an embodiment, the microphone disposed on the back portion of the housing is a primary microphone for the device. Such a device may also include a detachable microphone connected to the housing by a cable. The first end of the cable may include a microphone housing including a microphone as in Figure 31 and Figure 32 The microphone is further depicted in . The second end of the cable may include a connector that is complementary to the connector on the communication device housing. In an embodiment, the connector at the second end of the cable is secured to the housing connector with a screw to form a secure connection. In an embodiment, the microphone and cable are disposable. In an embodiment, the microphone and cable are reusable. The microphone housing is typically attached to the outer surface of the respiratory mask by clamping to a snap ring, which is attached to the respiratory mask by an adhesive pad. In some alternative embodiments, the first magnetic portion may be bonded to the respiratory mask and the second magnetic portion may be coupled to or formed as part of the microphone housing.

[0345] A microphone disposed on the back of the communication device housing (i.e., a housing microphone) and a microphone of the microphone housing at the second end of the cable (i.e., a wired microphone) can be used alone or in combination to pick up the user's voice. Advantageously, by placing one microphone on the outside of the respiratory mask and another microphone on the fluid delivery tube or coupler exiting the mask, the collection of the user's voice can be maximized or optimized. Optionally, the front of the communication device can include a third microphone for picking up ambient or environmental noise for noise cancellation. As described herein, the signals from the first microphone, the second microphone, and the third microphone can be used to generate an amplified voice signal for projection by a speaker located on the front of the housing and behind a grille or sound transmitting portion on the front of the housing. Additionally or alternatively, the voice signal can be transmitted via Bluetooth to an external device or speaker for amplification and / or playback.

[0346] In yet another embodiment, an application (i.e., software) running on the processor may include both sound output features and device control features. Capturing speech through materials (e.g., mask materials) presents unique challenges not present in other voice amplification technologies. This is because each type of mask has a unique transfer function that affects the voice of the mask wearer. These transfer functions will affect or degrade the characteristics of the voice being used, including loudness, frequency response / spectral balance, and coloration / distortion. Therefore, to a third party, the mask wearer's voice will not only be muffled, but will also sound different from their normal voice based on the intermediate mask material, which alters the transmission of different frequency components of the user's voice.

[0347] Recognizing this unique challenge, the present disclosure further provides an application that includes a profile feature. Respirators from different manufacturers, as well as different models from the same manufacturer, can have different shapes and constructions (materials, material thickness, etc.), which means they will have unique sound transmission characteristics. To correct for the mask wearer's speech altered by the mask, the profile feature includes one or more profiles that correct the user's speech to approximate the frequency and loudness characteristics of normal speech without the mask.

[0348] Figure 39 An audio spectrum is depicted, showing sound pressure level (SPL; y-axis), or loudness, as a function of frequency (x-axis, logarithmic scale) from 100 Hz to 20 kHz. The graph shows three amplified signals (speech through a cloth face mask, speech through a soft plastic respirator, and speech through a hard plastic respirator) compared to normal speech levels. As can be seen from the spectrum, these amplified signals overlap well with each other and approximate the spectral shape of normal speech levels across much of the spectrum. Thus, the amplified speech projected by the communication device's speaker effectively and advantageously mimics the user's voice, as if no intervening mask were present.

[0349] Figure 40 Depicts an example comparison between the spectral response of speech through a cloth mask with the communication device turned on and off. The spectrum with the device turned on was generated using a mask-specific profile that amplifies frequency components suppressed by the mask. Figure 41 ) and hard plastic respirators ( Figure 42 ) provides further examples. When comparing the "off" spectral responses, it becomes clear that different mask types have significantly different effects on the transmitted speech signal. Given these differences, it is possible to create a profile that compensates for the negative impact of the mask on the wearer's speech.

[0350] In an embodiment, the application includes one or more sound profiles, each specific to different types of facial masks. In an embodiment, the application includes one or more sound profiles, each associated with different mask materials (cloth, paper, fabric, soft plastic, hard plastic, etc.). In an embodiment, the application includes one or more sound profiles, each associated with different mask materials and material thicknesses. In an embodiment, the application includes mask-specific profiles for signals from masks produced by major vendors.

[0351] These configuration files can be pre-loaded into the application and can be stored in the device's data storage device or in a cloud server for retrieval by the application. In one embodiment, the application runs on a processor of the communication device. In another embodiment, the application runs on a processor of a mobile computing device (e.g., a mobile phone, tablet computer, or laptop computer), and the mobile computing device communicates with the communication device via a wireless communication protocol such as Bluetooth or WiFi.

[0352] The profiles can be used to modulate audio within a communication device or a wireless (and optionally wired) connected mobile computing device. In the case of a communication device modulating audio (i.e., user voice), the communication device may include a non-transitory data storage device (e.g., flash memory) for storing one or more profiles, and may include a transient memory operable with a processor to modulate the user voice audio for projection by a speaker. In an alternative embodiment, the voice signal may be transmitted to the mobile computing device for modulation according to the selected profile.

[0353] The profile settings of the communication device can be configured in various ways. For example, the communication device may include multiple pre-loaded profiles that can be set using the communication device's buttons. An LED indicator or audio played by a speaker can indicate to the operator (e.g., the user or hospital staff) which profile is being selected. For example, if ten profiles are pre-loaded, the LED or speaker can indicate the current profile by flashing a number of times or playing "1, 2, 3...", etc. In another embodiment, a profile is selected by an application running on the processor of the mobile computing device. The profile can be one of several pre-loaded profiles on the communication device's data storage device, or can be uploaded to the communication device from an application on the mobile computing device via a wireless communication protocol such as Bluetooth or WiFi. The communication device can have additional storage for custom profiles that are not pre-loaded, allowing the user to obtain additional profiles from cloud storage.

[0354] Figure 43 An exemplary embodiment is depicted in FIG, although variations of this exemplary embodiment are contemplated. For example, the communication device 4300 described herein is attached to a mask worn by a mask wearer. In an embodiment, the communication device 4300 may be a device such as Figure 39 The communication device may include one or more microphones 4302 that receive user voice audio transmitted through the mask material and any air space between the mask material and the microphones. One or more audio processing circuits 4304 are operably connected to the one or more microphones. The audio processing circuits 4304 may include, for example, an analog-to-digital converter (ADC) and an optional preamplifier. The audio processing circuits are operably connected to a processor 4306 that can modulate the audio signal based on device settings, including profiles. Temporary memory (not shown) may be operably connected to the processor 4306 for performing processor functions. A data storage device 4310 may be operably connected to the processor, the data storage device including one or more profiles. It should be understood that in some embodiments, the non-temporary data storage device may be removed, and the temporary memory may temporarily store profiles or aspects of profiles obtained from a linked mobile computing device. However, the data storage device is depicted for clarity in illustrating the profile feature.

[0355] These various features, including the processor 4306, data storage device 4310, microphone, speaker, wireless communication circuitry, or any other circuit components, may be included on one or more printed circuit boards (PCBs). Alternatively, these features may be incorporated into a chip. In various embodiments, the chip may be programmable or programmed to perform the features and functions described in the various related communication devices.

[0356] The data storage device 4310 may include one or more pre-loaded configuration files 4312. A "configuration file" may alternatively be referred to as a "speech output configuration file." Figure 43 In the exemplary embodiment of , three pre-loaded profiles 4312 are shown, although there may be more or fewer profiles. In some embodiments, there are no pre-loaded or default profiles, and only custom profiles exist. One or more custom profiles 4314 may optionally be stored in a data storage device or used by the communication device 4300. Custom profiles are typically not created by the user, but 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 that mask. The downloaded custom profiles allow old communication devices to be compatible with new masks. Advantageously, the communication device does not need to be updated with new firmware or hardware, as these profiles will be compatible with both old and new communication devices 4300.

[0357] Similarly, the data storage device 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. It should be understood that this selection is an internal device setting stored on a temporary or non-temporary memory and is not necessarily displayed on the screen. Nevertheless, it is contemplated that some embodiments of the communication device may include a display screen. The set profile may be read out from the communication device in various ways. For example, the communication device 4300 may include an LED that flashes to indicate the set profile when a user presses a button on the device. Alternatively, a speaker may audibly indicate the current profile setting by number or by an assigned name or any other identifying label. These features of identifying the set profile via the device are not required in all embodiments, as an application running on the mobile computing device may be used to display and select the relevant information, as described further below.

[0358] Communication device 4300 will typically include wireless communication circuitry 4308 for connecting communication device 4300 to mobile computing device 4350. Mobile computing device 4350 may be a mobile phone (smartphone), handheld computer, tablet computer, laptop computer, etc., and will typically include the necessary hardware and software to perform the functions described herein, as will be understood by those skilled in the art. Mobile computing device 4350 includes an application 4360, which includes a graphical user interface (GUI) and software instructions for performing the functions described herein. The GUI typically displays information to the user or healthcare professional, including the connection status with communication device 4300 and the current profile selected. The profile 4362 displayed in application 4360 typically corresponds to the profile on communication device 4300. Mobile communication device 4350 and communication device 4300 may undergo a synchronization process, allowing mobile computing device 4350 to display the profile loaded on communication device 4300. For purposes of example, the GUI may display communication device profile 4362 as well as other profiles not currently loaded on or in use by the communication device. If the user selects a profile that does not exist on the communication device, the system can automatically upload the profile to the communication device so that it is immediately available. The communication device 4300 can have a preset number of custom profile slots, and if the profile slots are full, one or more custom profiles can be deleted when a new custom profile is uploaded. The application 4360 can additionally display a "cloud profile" 4364 to the user or operator. The cloud profile 4364 can be downloaded to the mobile computing device 4350 from the cloud server 4380 or from another internet-connected location. The difference between a custom profile and a cloud profile is whether it has been downloaded for use by the system. In other words, if cloud profile X is downloaded, it can be added as custom profile C, or it can replace custom profiles A or B based on user preferences. In this way, the user can instantly obtain updated profiles as long as there is an internet connection.

[0359] The communication device 4300 may be pre-loaded with certain profiles (e.g., 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 market-leading masks that are expected to be encountered in a hospital or medical setting). In this way, a profile with acceptable sound quality may be selected even in situations where internet access is unavailable.

[0360] In yet another embodiment, the application may include a feature that allows for the generation of custom profiles for specific masks or face coverings. For example, the mobile computing device may prompt the wearer to speak a certain sentence, and the mobile computing device's microphone may detect the frequency components of the user's voice with the communication device turned on or off. Alternatively, an experienced user may adjust one or more parameters of a given profile in the expert mode of the application 4360 to optimize sound quality.

[0361] The profile 4362 may include further instructions for display to the user or operator via the GUI. For example, for a particular mask, optimization may be performed using one or more microphones 4302 of the communication device 4300 placed at specific locations on the mask. Thus, the GUI may instruct the operator to place the microphones 4302 at similar or identical locations on the mask for optimal collection of the user's voice. Alternatively, the microphones 4302 may be placed according to general instructions. In yet another embodiment, the application 4360 may include a placement optimization feature that instructs the user to change the position of one or more microphones 4302 if the sound quality (i.e., the spectrum of the projected voice) deviates from the expected spectral profile.

[0362] In various embodiments, a "profile" (alternatively referred to as a "voice output profile") can compensate for frequency-dependent transmission losses of a user's voice through a mask. In conjunction with the examples provided, the devices, systems, and methods herein advantageously address technical issues related to different masks having significantly different spectral or frequency-dependent sound transmission profiles. Compensating for these differences is crucial for projecting output sound that more accurately resembles the user's voice. This is particularly important in end-of-life situations, where many patients may need to wear respiratory masks, or in emergency situations where protective masks or head coverings are required, for the user's voice to be recognizable by loved ones or others. In this context, "compensation" does not necessarily mean that the output voice will exactly match the user's voice without the mask, but rather that it will approximate the user's voice in terms of the audio spectrum (frequency). Additionally, "compensation" does not necessarily mean that the amplitude or volume will exactly match the user's voice without the mask, but rather that it can be similar or louder depending on the desired amplification level (volume), which can be adjusted by a connected application on the communication device or mobile computing device. Amplification of the sound signal or sound data can be performed at various stages, for example, after the microphone collects the sound but before conversion to a digital signal, after conversion to a digital signal but before modulation, after modulation, or at the speaker amplifier / speaker projection stage. These are exemplary, and analog devices in general are also contemplated. It is also possible that amplification occurs at some stage of the device's function (e.g., at the microphone preamplifier), while the speaker volume may still be set to a lower volume than normal speech level.

[0363] Generally speaking, amplification of a speech signal or speech data involves changing the amplitude of substantially all of its frequency components, while modulation of a speech signal or speech data involves changing the amplitude of fewer than substantially all of its frequency components (e.g., changing the amplitude of only some frequency components). Advantageously, the profiles or sound output profiles disclosed herein provide for adjusting certain frequency components of the speech signal or speech data based on the mask's construction materials or design (model, size, type, etc.). Additionally, in many embodiments, the communication device may include a microphone positioned near or coupled to the fluid delivery tube, as well as a microphone positioned on the mask's exterior surface—in such cases, the sound output profile can be optimized for speech signals or data from microphones in these locations. In some embodiments, the sound output profile is optimized for microphone configurations that include similar microphone placement (devices with one microphone, two microphones, etc.). It should be understood that corresponding sound output profiles are contemplated for any relevant device disclosed herein. Additionally, it should be understood that various aspects of the profile can be included or run on a communication device, mobile computing device, cloud computer, internet server, etc., to modulate the speech signal to compensate for transmission losses through the mask.

[0364] In another embodiment, 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 the following: the number of microphones, the location of the microphones, the material of the mask, the manufacturer of the mask, the manufacturer model of the mask, the patient's age, the patient's gender, the patient's medical history, patient voice samples from different audio devices, patient voice samples from a communication device, patient voice samples with a profile or filter applied, or any other useful input data. Therefore, in another embodiment, a method for training a machine learning algorithm including one or more of the above inputs and a method for optimizing a voice profile using the trained machine learning algorithm are provided. Devices and systems that include or utilize machine learning to create or optimize profiles are also provided.

[0365] Applications of the mobile computing device can perform other functions including voice recording and / or transcription. For example, in addition to projecting amplified voice by the communication device, the voice signal can also be recorded or transcribed by the communication device, or alternatively, the voice signal can be transmitted to the mobile computing device for recording and / or transcription. Optionally, a profile can be applied to the recorded voice signal so that the voice signal most closely resembles the unsuppressed voice of the speaker. Additionally, the profile can be utilized to optimize the voice signal for improved recognition by a transcription program or feature. Transcription can be performed by an onboard speech-to-text program, a speech-to-text program on the mobile computing device, a speech-to-text program on a cloud computer, or a combination thereof. In some embodiments, the transcription can be displayed on the mobile computing device or other display to enable the patient to communicate with a hearing-impaired third party.

[0366] In various embodiments, the communication device of the present disclosure may include a housing having or containing one or more microphones. The microphone may be contained internally or positioned adjacent to a sound-transmitting portion of the housing. The sound-transmitting portion may be a passageway aperture that allows sound to reach the microphone, and it is contemplated that the microphone may be mounted within such a sound-transmitting portion. The sound-transmitting portion of the housing may also include a grille made of the same or different material as the housing, optionally formed as part of the housing. In alternative embodiments, the sound-transmitting portion may be a thin or membrane-like material that does not allow significant permeation of air or fluid but effectively transmits sound. In some alternative embodiments, if the housing is constructed of a material that transmits sufficient sound, the sound-transmitting portion may be a portion of the housing body to which the microphone is mounted to capture sound transmitted through the housing. In various embodiments, the sound-transmitting portion may be positioned against or in close proximity to certain mask features (such as the mask surface, the fluid delivery tube, the coupling between the mask and the fluid delivery tube, etc.). "Close proximity" should be interpreted as sufficiently close to collect the user's voice for the described operation of the communication device. In some cases, "close proximity" may include one or more contact points between the sound-transmitting portion (or, alternatively, a portion of the microphone, if the microphone is positioned within the sound-transmitting portion) and a mask feature. In other embodiments, the sound transmitting portion of the shell can be positioned close to, but not contacting, the mask features (e.g., within approximately 0.1 to 5 cm, or 0.1 to 2 cm, or 0.1 to 1 cm).

[0367] The communication device may also include sensors for detecting ambient or exhaust gas mixtures or temperatures. Monitoring gases (such as air quality and temperature) can be useful for respiratory treatment of patients, for emergency personnel, or in any scenario where a user requires a mask. The device may include a separate membrane or filter for real-time sampling or analysis of ambient or exhaust air quality for pollutants, particulate matter, or pathogens. The membrane may be removable, replaceable, or cleanable. Sensors in the device may include relative or absolute humidity sensors, temperature sensors, dew point sensors, enthalpy sensors, pressure sensors, barometric pressure sensors, flow rate sensors, oxygen sensors, carbon monoxide or carbon dioxide sensors, nitrogen sensors, or combinations thereof. Sensors may detect or monitor characteristics unrelated to air quality and may include acoustic sensors, light sensors, cameras, ambient temperature sensors, accelerometers, or any other sensor related to the exhaust or ambient environment. It is also contemplated that sensors may be located external to the device but connected to ports on one or both of the internal or external housings.

[0368] In operation, the device can detect the user's voice or sound via a microphone and reproduce the sound via a speaker. The device may include a microphone, a speaker, a processor, a battery (disposable or rechargeable), a charging / data port, communications such as Bluetooth®, a volume control, a light, a light-emitting display (LED), a camera, a video screen, and a measurement port capable of electronically measuring breath (and / or water vapor expelled from the user's mouth), noise, voice, tone, etc. The microphone may have noise cancellation capabilities. The device may provide communication between internal and external components and any external systems via any wired or wireless connection (e.g., RFID, Wi-Fi, Bluetooth®, Zigbee, Zwave, 2G, 3G, 4G, 5G, or any reasonable subsequently developed wireless method).

[0369] The device may also include a feedback unit for the user (e.g., headphones or in-ear components). The feedback unit can assist the user in hearing the user's speech. The feedback unit may also include an external microphone embedded in an external element or connected to but separate from the external element. The external speaker can transmit sound to the user's ear. The feedback unit may be sized and configured to include additional microphones at other locations around the user (e.g., the user's throat). The feedback unit may be useful with a mask, helmet, or other item that covers or insulates the user's head.

[0370] It is contemplated that the device may include any other reasonable technology, system, or process to facilitate communication between a user and another person. These technologies include microprocessors, microcontrollers, computer chips, programmable algorithms for processing data (including sound) on the device, any components for capturing sound and human speech, speakers and any technology for projecting sound and human speech, noise cancellation technology, wireless capabilities for communication between the microphone and speakers, and between the device and remote devices (e.g., external speakers, portable / cellular phones, watches, computers, and televisions). The device may include speech enhancement technology and speech recognition / speech reproduction technology, as well as voice command technology such as found in personal digital assistants (PDAs) such as Amazon® Alexa®. The device may include machine learning and other programming code that will learn the user's voice and optimize the system for that voice or regenerate speech based on the user's voice. Machine learning or artificial intelligence (AI) may be utilized to create, support, or optimize various features of the disclosed devices, systems, and methods. For example, machine learning or AI may be utilized to optimize the input and output of a communication device. AI-based speech translation may be implemented onboard the communication device, on a connected mobile computing device, or in the cloud. In some embodiments, optimized audio from a speech output profile may be utilized as input for speech translation or AI-based speech translation. Using optimized audio from a speech output profile can be particularly advantageous for AI speech translation that preserves one or more acoustic characteristics of the user's speech. For example, the AI ​​speech translation can provide an amplitude match at one or more frequencies of the user's speech spectrum, meaning that the amplitudes of the profile-corrected untranslated speech and the resulting translated speech can approximately match at one or more frequencies of the user's speech spectrum.

[0371] The wearer's speech can be translated into a third-party language via a translation service (e.g., Amazon Translate, Google Cloud Translate, or Microsoft Translator). Alternatively, the communication device can include all the hardware and / or software necessary to perform onboard speech translation in real time with minimal delay (i.e., approximately 0.5 seconds or less than approximately 5 seconds) between spoken words and projected translations. An application running on the smartphone can interface with the communication device and system to change or implement any of the described settings or features. In another embodiment, other functions performed by the communication device itself, an external computing device such as a smartphone or computer, and / or a cloud computer include speech translation, speech transcription, accent translation, and / or voice recording. Voice recording and / or transcription embodiments can interface with local or cloud storage devices to save speech audio and / or transcribe the user's spoken words into text, respectively. Such embodiments can be advantageously used for medical records or for recording any other user speech. The volume of the speech can be increased based on on-device settings and voice processing within the unit. This speech can be altered, for example, via an electronic speech synthesizer or similar technology. The device may include hardware or software acoustic filters in the device that may reject sounds outside the human speech range.

[0372] In yet another embodiment, one or more components may be located in a positive air pressure device (e.g., a BiPAP or CPAP device fluidically coupled to a respirator mask via a fluid delivery tube). For example, it has been discovered that sound transmitted from the respirator mask to the positive air pressure device via the fluid delivery tube can be captured by a microphone in the positive air pressure device for efficient amplification or for use in other features such as transcription, recording, translation, etc. as described herein. For example, Figure 44AA respiratory mask 4400a is depicted coupled to a fluid delivery tube 4410a. The fluid delivery tube is shown in dashed lines but continues from the mask 4400a to the positive air pressure device 4450a. In an exemplary embodiment, a microphone 4420a is disposed within or associated with the positive air pressure device 4450a. For example, the microphone 4420a may be located within or near the fluid air space of the positive air pressure device 4450a, or may be separated from the fluid air space by a sound-transmitting material (e.g., a filter, membrane, plastic, or other material). The user's speech picked up by the microphone 4420a can then be utilized by any other components 4430a (including, but not limited to, analog components, digital components, processors, speakers, 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 play back the amplified speech from an integrated speaker or transmit the amplified speech to another device or speaker. In another embodiment, the positive air pressure device 4450a can transmit the original or processed voice signal to another device (e.g., a mobile computing device) for processing / playback. It will be appreciated that the positive air pressure device 4450a can include any features related to the concept of capturing the user's voice through the microphone of the positive air pressure device 4450a.

[0373] Alternatively or additionally, one or more microphones (e.g., 4420b and 4420c) can be located on or associated with the respiratory mask, such as Figure 44B Although Figure 44B The positive air pressure device 4450b is shown without a microphone itself, but it is contemplated that another microphone may be present in the positive air pressure device in addition to the one or more microphones associated with the respiratory mask. As taught herein, when one or more microphones 4420b or 4420c are associated with the respiratory mask or its fluid delivery tube coupling portion, they may be connected to the positive air pressure device via one or more wiring 4425. Alternatively, one or more of the microphones may be wirelessly connected to the positive air pressure device 4450b. Figure 44AAs with the example of , the positive air pressure device 4450b can include any audio component 4430b to process the user's voice from the microphone or transmit the raw or processed user voice signal to an external device. It is also contemplated that the positive air pressure device (4450a, 4450b) can include selectable voice output profiles as taught herein.
