Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This international application claims priority to U.S. Provisional Application No. 63 / 425,167, filed November 14, 2022, which is incorporated herein by reference in its entirety.

[0002] The present disclosure relates to a modular communication device for use with mouth, nose, face, and head coverings, including masks and hoods and non-invasive ventilation (NIV) masks or respirators. Modern societal health concerns often require the use of such coverings and / or masks to protect the wearer from exposure to external air, liquids, particulates, pathogens, or other harmful substances. While masks and hoods may protect the wearer, they also impede communication by reducing or dampening the wearer's voice. The present disclosure provides a modular communication device that can be attached to or interfaced with a disposable or reusable mask or hood and allow the user's voice to be amplified outside the mask or hood for communication with third parties. The present disclosure also provides systems and devices for capturing the voice of the respirator, mask, or hood wearer on the respirator or within a fluid delivery tube, which rebroadcast or amplify the wearer's speech for communication with third parties. Communication devices and associated systems and methods may advantageously involve sound output profiles to compensate for speech sound transmission losses through masks, face coverings, respirators, or hoods. Sound output profiles and additional features, including audio transcription and / or recording, may be included within or by such communication devices, connected mobile computing device applications, or internet-connected servers / clouds.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In the case of conflict, the present description will control.

[0143] As described above, the present disclosure, in some embodiments, relates to a patient respiratory mask including a microphone disposed thereon, the microphone configured to interface with a wired or wireless speaker and / or a wired or wireless communication device, such as a telephone. In some embodiments, the present disclosure relates to a modular communication device for use with a mouth, nose, face, and head covering, including a mask. The present disclosure provides a modular communication device that can attach to a disposable or reusable mask or face covering and allow a user's voice to be amplified outside the mask. While the following is described with reference to various exemplary embodiments, the present disclosure is not so limited.

[0144] In some exemplary embodiments, the microphone is a noise-canceling 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 communication device are wireless. References to components such as microphones, speakers, etc. that are wireless or transmit wirelessly should be understood to encompass configurations in which such devices are connected to components that include wireless transmitters and / or receivers. Thus, any reference herein to a "wireless" component should be read to encompass such configurations. In further exemplary embodiments, an on-board speaker is integrated into a portion of the respiratory mask. In further exemplary embodiments, the speaker is external to the mask.

[0145] As mentioned, in exemplary embodiments, the patient respiratory mask includes an internal and / or coupler or tube-compatible noise-canceling microphone with wireless, e.g., Bluetooth®, capabilities. In exemplary embodiments, the microphone is attached to or built into the respiratory mask, the 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 a microphone, a speaker, wiring, a processor, and a communication device. In exemplary embodiments, one or more of the preceding elements are embedded in or provided through a portion of the coupler.

[0146] As discussed above, in a further exemplary embodiment, the microphone wirelessly transmits the patient's voice via Bluetooth technology to a Bluetooth speaker in proximity to and in communication with a Bluetooth transmitter. References herein to a "Bluetooth" device refer to a device that is enabled to use Bluetooth technology. In a further exemplary embodiment, the microphone wirelessly transmits the patient's voice via Bluetooth technology to a Bluetooth speaker and / or a Bluetooth smartphone in proximity to and in communication with the Bluetooth transmitter. While a Bluetooth speaker and an exemplary Bluetooth smartphone are specifically described, the present disclosure contemplates other Bluetooth communication devices.

[0147] 1 , an exemplary patient respiratory mask according to the present disclosure includes an exemplary microphone provided therein. In the exemplary embodiment, the respiratory mask is a CPAP (or BIPAP) respiratory mask (generally shown at 10) with a mask portion 12 and a Bluetooth® microphone 14 integrated into a fluid cavity (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.

[0148] In an exemplary embodiment, the microphone 14 is mounted on or provided within the material of the mask. In another exemplary embodiment, the microphone is provided within a separate microphone tube (not shown) that may extend at least partially into the fluid cavity of the mask 10. For example, the microphone tube may be formed as part of the coupler or inserted into the mask or coupler. The microphone tube is generally positioned within or adjacent to the internal cavity of the mask, coupler, or fluid delivery tube. In some embodiments, the microphone tube is removably insertable into a port or opening on a respirator, mask, PAPR hood, or the like. The microphone tube generally has a tubular structure that houses a microphone disposed within the tube such that the tube collects sound to be picked up by the microphone. In a further exemplary embodiment, the microphone tube is at least partially sealed, e.g., via a plastic or membrane that is at least moderately permeable to sound but also separately maintains the integrity of the fluid cavity 16 within the respirator 10.

[0149] Such exemplary microphone tubes may be provided within or mounted to the respiratory mask 10, the intermediate fluid delivery tube 18, or any coupler 22 or portion interposed in the fluid delivery tube 18 of the respiratory mask 10.

[0150] 2, another exemplary patient respiratory mask 10 incorporates such a Bluetooth® microphone 14 in 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 the fluid delivery tube 18 on the other side. Referring to FIG. 3, the exemplary coupler 22 includes a mask inlet side (generally indicated at 32) and a fluid delivery tube side (generally indicated at 34), with bulk airflow traversing the interior of the tube (generally at arrow 36).

[0151] In the exemplary embodiment, the microphone 14 is separated from the bulk airflow 36 by a filter 38, which may be configured to filter one or more sound characteristics or simply shield the microphone from the bulk airflow. The filter 38 may be a membrane, an acoustic mesh, or any other convenient sound-transmitting material.

[0152] In the illustrated exemplary embodiment, the microphone is illustrated as operably connected to a microphone preamplifier 40, equalization components 42 (e.g., an analog-to-digital converter (ADC) and digital signal processor (DSP)), sound output components such as a Bluetooth® transmitter 44, a digital-to-analog converter (DAC), an amplifier (Amp) and speaker 45, an antenna 46, and a power source 47, such as a battery or wired power adapter. These components are illustrated in this exemplary embodiment as both connected to the microphone and housed on a protruding portion 48 of the combiner 22. However, it should be appreciated that the microphone may be configured on-board the combiner 22 with more or fewer associated components, with some components or processes being omitted or implemented anywhere, e.g., external to the combiner 22, remote from the combiner 22, etc.

[0153] Additionally, the coupler may take any convenient shape when storing such components, so long as connecting portions 32 and 34 are configured to connect to mask inlet 20 and fluid delivery tube 18, respectively.

[0154] In exemplary embodiments, the coupler may be configured to attach to fluid delivery tubing regardless of any variations in tubing diameter (e.g., configuration differences justifying the use of 19 mm inner diameter standard tubing versus 15 mm inner diameter thin tubing). Thus, exemplary embodiments provide a universal attachment (e.g., a clip, as shown in FIG. 4, etc.) configured to fit a variety of tubing and respiratory devices.

[0155] In other exemplary embodiments, the microphone or other electronic component is configured to be attached (e.g., as a clip-type attachment, among others) external to the respiratory mask 10 but in proximity to the patient's fluid cavity (see 16 in FIG. 1 ). Referring now to FIG. 4A , a clip 50 is illustrated with the microphone unit 14 provided on the underside of the clip. In the exemplary embodiment, the clip 50 also interfaces with power and signal wires 54 via port 56. While such a clip can be configured to attach anywhere it is convenient to place the microphone unit 14 near a sound-transmitting surface, for example, the inlet portion 20 of the mask 10 or an external portion of the coupler 22, FIG. 4 illustrates the provision of the clip 50 over a portion of the fluid delivery hose 18, with the microphone unit pressed against or in close proximity to the material of the hose so as to pick up sound vibrations transmitted through the hose. While FIG. 4 illustrates a wired configuration, it should be appreciated that the microphone unit may also be configured with a battery and wireless (e.g., Bluetooth®) transmitter. FIG. 4B illustrates an exemplary side view of clip 50 positioned adjacent tube 18 with microphone 14 disposed therein.

[0156] 5, a fluid delivery tube 18 is illustrated as incorporating a microphone 14 (see FIG. 2) therein and including an integrated coupler 22 that is attachable to or integral with the respiratory fluid delivery tube 18. An exemplary power cord 24 extends along at least a portion of the tube 18 to the microphone 14 (which may be configured as a wired or wireless, e.g., Bluetooth®, arrangement). As described above, the coupler may also include other components, such as processing or filtering components, a speaker, a wireless transmitter, wiring, or any other type of communication device in addition to or as an alternative to the microphone.

[0157] In further embodiments, microphone 14 may be configured as a wired microphone, utilizing exemplary cord 24 or another cord for data transmission. In additional exemplary embodiments, the microphone may be wireless and connected to a battery source without a cord running along a portion of tube 18.

[0158] In further embodiments, the cord may be configured with one or more clips to secure it to or as an integral part of the hose 18, for example, buried or permanently attached to the conduit 18 or conduit wiring harness. An exemplary wire harness clip 62 is illustrated in FIG. 6 as attaching the cord 24 to the conduit 18. In the exemplary embodiment, the cord 24 is configured as a wiring harness that is secured in one or more locations via harness clips 62, with the cord connectable to the coupler 22 (as in FIGS. 2 and 3) or the mask (as in FIG. 1). As with any wired configuration, the end of the cord 24 remote (from the mask) may be configured to connect to additional components such as a speaker, processor, network, power, etc.

In a further exemplary aspect, both modes are configured, and the system is configured to switch between modes automatically or manually (via a switch or application).

[0174] In a further embodiment, an application running on the processor controls one or more aspects of the system, including, but not limited to, speaker or communication device modes, noise filtering / cancellation or processing parameters, microphone parameters, wireless connections to devices, and monitoring for new devices within range.

[0175] In further embodiments, power for one or more components is supplied by a power cable with any convenient terminal end, for example, a 110 volt outlet terminal, USB, Lightning connector, or the like.

[0176] In other embodiments, bone induction or in-ear, behind-the-ear, or canal hearing aids provide or deliver sound signals to the patient using bone induction or hearing aid equipment that communicates wired or wirelessly with the respiratory mask system.

[0177] In an embodiment, when a user (patient) of a respiratory mask speaks, the user's voice will be captured by a noise-canceling microphone as the sound reaches the internal structure of the mask and / or travels down the tubing. Once the voice is captured within the device, it is transmitted via Bluetooth technology to a freestanding speaker where the voice will be amplified. In other exemplary embodiments, the voice is transmitted to a speaker on the mask, coupler, or tubing where the voice will be amplified.

[0178] In other embodiments, the system is configured to distinguish between direct human interaction (speech) and digital interaction (e.g., audio signals from a mobile phone) and automatically switch output to one of multiple possible wireless communication devices depending on the detected signal. Alternative automatic or manual switching is also contemplated herein with respect to the exemplary embodiment for switching between a nearby Bluetooth speaker and a communication device (e.g., a mobile phone facilitating a patient's conversation with a remote individual). In other embodiments, multiple Bluetooth devices may be simultaneously connected via bridging capabilities. Such switching or bridging capabilities may be provided, for example, with a microphone or anywhere within range of a Bluetooth microphone. In other embodiments, multiple Bluetooth devices may be simultaneously connected via multiple connections or modes.

[0179] While embodiments have been shown and described, it will be apparent to those skilled in the art that 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 embodiments described above should be read in a non-limiting manner, both with respect to structure and methodology. Thus, it should be understood that the various embodiments have been described by way of illustration, and not limitation.

[0180] In some embodiments, the device may be a communications device sized and configured to be used in conjunction with a mask or other device intended to cover the user's face, nose, mouth, and / or head. Commonly used face masks make communication more difficult by dampening and muffling the user's voice. Wearing a mask can reduce the inherent effectiveness of a mask by requiring the mask wearer to stand closer together, shout, or remove the mask to properly communicate. The disclosed communications device, when combined with a mask and when using a phone or other communications device, allows a disposable or reusable mask to improve a user's communications from a safe distance.

[0181] Masks may be made from fabric, paper, cardboard, plastic, or other materials. Masks may be used to conceal a user's identity, prevent the dispersal of gases, liquids, or particulates breathed or exhaled by the user, or 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 cloth masks, fabric masks, disposable masks, single use 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 coverings, handkerchiefs, scarves, veils, hoods, bandanas, masks with attachments, masks with fastenings, and combinations and layered arrangements thereof.

[0182] The communication device may be removably attachable to a disposable or reusable mask, which is particularly useful for medical professionals, patients, first responders, or those who desire to cover their nose and mouth and / or filter the air they breathe or exhale. The communication device may be reusable so that it can be removed from a first mask to a subsequent mask. In some embodiments, the communication device may be modular, with multiple parts that allow it to be attached to a mask. The communication device may include an inner and outer housing, or only one inner or one outer housing. The communication device may be autoclavable or sterilizable, or disposable.

[0183] The inner and outer housings of the communication device may each include any 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 plastic, metal, wood, or artificial or natural materials. Each housing may also include elements for securing the inner and outer housings to the mask and for providing a connection between the inner and outer housings. To connect the inner and outer housings to the mask, the inner and outer housings may include mechanical clips, springs, magnets, pins, hook and loop, snaps, buttons, glue or other adhesives, zippers, stitches, thread, string, staples, suction, or other connecting means. Certain features (e.g., snaps, buttons, zippers) may be complementary to features on the mask. The housings may be configured to slide into and reside within a pocket or other means of fastening on the mask. The inner and outer housings may be configured to attach to eyeglasses, a hat, or other wearable item that allows the inner housing to be in close proximity to the user's mouth or nose.

[0184] The inner and outer housings may each include a complementary magnetic attachment that allows the inner and outer housings to be attached to each other and is separated by a mask. The magnetic attachment provides a fixed and movable connection on the mask. The magnetic attachment may be a ring on each housing that provides a fixed connection between the inner and outer housings and securely attaches the communication device to the mask. The complementary magnetic attachments are paired with each other across the mask and still allow electrical signals to pass between the inner and outer housings. The complementary magnetic attachments may be rings, or squares, or any other shape with an open center. The complementary magnetic attachments may also be multiple complementary magnets on each of the inner and outer housings. The complementary magnetic attachments may have the ability to attach graphics or otherwise present a message on the outer housing as a form of free wording or advertising.

[0185] The inner and outer elements may also be sized to have complementary curved shapes. The curved shape of the inner element may be placed inside the mask, extending from one side to the other across the area in front of the user's mouth. The speaker may be located in a central location between the two sides to bring it closer to the user's mouth. Other features of the inner element, such as electrical and mounting features, may be located along the curved shape on the side of the microphone. The curved outer element may be attached to the inner element by a magnetic attachment in a location complementary to the inner element. In other embodiments, the element may be part of or attached to an inner support frame / bracket that supports the mask shape on the user's face.

[0186] The inner and outer housings may house 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. Due to the proximity of the housings, power may flow through the mask from the powered housing to the unpowered housing via induction or other modalities. Alternatively, a physical connection as described above may span between the inner and outer elements to provide power to the unpowered element or to exchange data between the elements. It is also envisioned that the device may mate with a mask having an existing port (for airflow, etc.) that allows a suitable path for a physical connection between the inner and outer elements.

[0187] One or both of the inner and outer housings may include ports and / or cables for power sources or charging, or for data transmission. The ports and / or cables may connect the housings, elements, and devices to another system for data or signal processing, charging, external speakers or communications, or any other related system.

[0188] The inner element is located inside the mask, close to the user's mouth, and can easily pick up the user's voice. The inner element may act as or include a microphone and 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 a signal from the inner element and then project the user's voice. The user's voice may be projected via a speaker in the outer housing, or the inner or outer housing may also transmit an audio signal to an external speaker or system. The speaker in the outer housing may project the user's voice along with 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 an expanding housing, such as a megaphone, to amplify the user's voice. Transmission of signals between the inner and outer elements may be wireless or via a physical connection between the elements. Wireless transmission between the inner and outer elements is suitable for reusable or disposable masks. Transmission of electrical signals through a physical connection may include an element extending from the inner or outer element that penetrates through the disposable mask and makes physical and electrical connection with the other of the inner or outer element. This connection is suitable for disposable masks or may be used with reusable masks.

[0189] In the communication devices and systems herein, the mask, hood, or other face covering may have various built-in aspects for engaging or interfacing with the communication devices and systems. The mask, hood, or face covering may have a built-in magnet or metal magnetic attachment, to which the magnetic portion of the communication device can releasably engage. The built-in magnet or magnetic attachment may eliminate the need for an internal housing, mask clip, or any other part inside the mask. Alternatively, the magnet or metal may be insertable into the mask. For example, the mask may include a slit for inserting the magnet or metal, or a standard disposable or multi-layer reusable mask may be slit with a knife to insert the magnet or metal, and then taped across the slit. It may be understood that any manner of incorporating the magnet or metal into the face mask or hood is contemplated.

[0190] In alternative embodiments, the microphone may be built into the mask or any other face covering or hood as a single-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, the mask may include a slit for inserting the microphone, or a standard disposable mask may be slit with a knife and then taped across the slit to insert the microphone. It may be understood that any manner of incorporating a microphone into a face mask or hood is contemplated.

[0191] In some embodiments, the mask or hood may include a built-in sound waveguide, such as a sound transmission pad. Such a sound waveguide optimizes the collection of sound within the mask or hood and routes it to a mounting area coupled to the waveguide, where a portion of the communication device connects to pick up the sound. The connection between the communication device and the mounting area may be a connector, adhesive, magnetic, or any other suitable connection. The mounting may be a physical connection that places a microphone or piezoelectric pickup in proximity to the mounting area and / or the waveguide. Optionally, the mask or hood may include a microphone or piezoelectric pickup coupled to the waveguide, and the communication device may electrically interface with the microphone or piezoelectric pickup.

[0192] The mask or hood may alternatively include a clip, pouch, slot, or other complementary feature with the housing of the communications device so that the device can interface with the mask or hood. In some embodiments, the communications device may include a microphone within a first housing (e.g., FIGS. 12-13), which is configured to interface with an integrated portion of the mask or hood instead of including a magnetic attachment. Generally, such an integrated connector would position the microphone substantially facing the mask wearer's mouth to pick up speech from the wearer.

[0193] In further alternative embodiments, the mask or hood may include all components necessary to pick up and amplify the wearer's speech. For example, the mask or hood may include 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 permanently or removably incorporated into the mask or hood, 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 may be releasably attached to the mask or hood.

[0194] The embodiments disclosed herein are generally useful for hoods, such as PAPR hoods. A "PAPR hood" is a portion of a powered air-purifying respirator that a user can wear for protection from environmental or biological hazards. Such hoods generally surround the wearer's head or head and neck and are connected to an external filtered positive pressure source, such as a battery-powered positive pressure source. PAPR hoods generally include a flexible or semi-rigid transparent plastic window that allows the wearer to see outside and allows the wearer's face to be visible from the outside. The term "PAPR hood," or more generally, "hood," is intended to encompass any hood, respirator, or similar safety or medical device that covers the user's head or face and provides 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.

[0195] Embodiments herein may be attached to such hoods using mechanical clips, springs, magnets, pins, hook and loop, snaps, buttons, glue or other adhesive, zippers, stitches, string, thread, staples, suction, or other connecting 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 the housing to the transparent window of a PAPR hood. Various "attachment portions" are contemplated for engaging portions of a communication device.

[0196] In some embodiments, a first housing having a microphone is provided in wired or wireless connection with a second housing having a speaker (see, e.g., FIGS. 12-13), although any described communication device configuration is contemplated. In some embodiments, the first housing having a microphone is releasably attachable to a mask or hood. In some embodiments, the first housing having a microphone is releasably attachable to a transparent window in a PAPR hood. In some embodiments, the second housing having a speaker may include a mechanical clip, spring, magnet, pin, hook and loop, snap, button, glue or other adhesive, zipper, stitch, string, thread, staple, suction, or other connection means for engagement with an article worn on a person.

[0197] In some embodiments, a first housing having one or more of the microphone and / or speaker may be releasably attachable to the mask or hood by a snap connector attachment portion. A snap connector generally has a circular stud that is engageable with a complementary socket. In exemplary embodiments, the hood or mask may include a snap connector stud or socket that is engageable with a complementary stud or socket on a device housing, such as the first housing that includes the 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 adhesive to the mask or hood, such as the transparent window of a PAPR hood. FIG. 27 shows an example of a stud with an adhesive pad and a socket-type connector that is complementary to the stud. In some embodiments, a communication system includes 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, one of the housings having a connector that is complementary to a connector on the mask or PAPR hood.

[0198] In some embodiments, the mask or PAPR hood includes an integrated magnetic attachment portion. For example, the mask or PAPR hood may include a magnet, a ferromagnetic material (such as metal or iron), or a ferrimagnetic material. For convenience, the term "metal" will be used to refer to a ferromagnetic or ferrimagnetic material that is engagable with a magnet. The mask or PAPR hood may have a permanently attached, embedded, or bonded magnetic or metal attachment portion that is complementary to the magnet or metal on the housing of the communications device. In some embodiments, the communications device may have a first housing with a microphone, and the housing has a magnet disposed on an exterior surface that is complementary to the magnet or metal attachment portion associated with the mask or PAPR hood.

[0199] For example, as shown in Figure 28, a PAPR hood may include a recessed, attached, or adhered portion for releasable engagement with a portion of a communication device. Similarly, any other type of mask may include a recessed, attached, or adhered portion for releasable engagement with a portion of a communication device. While the portions outlined in Figure 28 are shown in specific locations on the PAPR hood window, it will be understood that any adhered or otherwise attached portion can be located in any useful location (generally to place a microphone in proximity to the user's mouth).

[0200] In some embodiments, a magnet or a metal complementary to a magnet may be adhesively attached to the interior of a mask or PAPR hood window as an adhesive attachment portion. FIG. 29 shows an exemplary embodiment of an adhesive attachment portion that houses or embeds a metal or magnet. The adhesive portion generally has a flexible support coated on one side with an adhesive. The metal or magnet generally is located on the surface of the adhesive side or embedded within the adhesive portion. The metal or magnet is optionally coated with an adhesive. The adhesive portion may be a single-use, optionally sterilized, portion for adhering to the interior of a PAPR hood window. Advantageously, the adhesive portion can be placed anywhere on the interior of the PAPR window such that the magnetic (or alternatively, metal-containing) portion of a communication device can releasably engage with the metal or magnet of the adhesive portion, securing the magnetic portion of the communication device to the PAPR window. The adhesive attachment ensures that the attachment portion cannot become loose or come loose within the PAPR hood or mask during use or when the communication device is removed.

[0201] In some embodiments, the 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 some embodiments, the metal or magnet of the adhesive attachment portion and the communication device are complementary ring-shaped metals or magnets that surround a microphone or microphone opening in the housing of the communication device. In some embodiments, the PAPR hood may include a sound-transmitting surface for the attachment portion of the communication device. The sound-transmitting surface may be a PAPR hood window, a separate portion of the hood, or a portion of the PAPR hood window, which may be the same or a different material as the remainder of the PAPR hood window. In an alternative embodiment, the metal or magnet is coated directly with an adhesive for adhesion to the inner surface of the PAPR hood window.

[0202] In an alternative embodiment, the communications device is secured to the other (outer) surface of the PAPR hood window by a screw or bolt with a nut fastener on the other side. The nut fastener or communications device may include a gasket around the threads for an airtight seal. A plug or seal may be used to keep the hole in the PAPR hood window airtight when the communications device is not in use. Alternatively, a bracket may screw onto the PAPR hood window, allowing the communications device housing to dock against the PAPR hood window (e.g., microphone housing). The bracket or docking connector may alternatively be formed as part of the PAPR hood or PAPR hood window, allowing the housing to dock in place for use.

[0203] 30 depicts an exemplary embodiment of a microphone portion of a communication device releasably attached to a PAPR hood window. As disclosed herein, the microphone portion is generally a microphone housed in a housing configured to pick up a user's voice through a mask or PAPR hood. In the depicted embodiment, a first housing releasably attached to the PAPR hood window houses at least the microphone, and the first housing is in wired or wireless communication with a second housing that houses at least a speaker. The microphone and speaker are operably connected as disclosed herein. In an alternative embodiment, the microphone and speaker may both be releasably attached to the PAPR hood window, with the microphone and speaker housed in the same or separate housings.

[0204] Additional attachment types are also contemplated, for example, attachments that do not require a separate attachment portion on the mask or hood to engage with the communication device housing. In some embodiments, the microphone may be provided in a housing configured to adhesively attach to the exterior surface of the PAPR hood window. FIG. 31 depicts an embodiment having a microphone housing with a raised edge for engagement with the 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 some embodiments, the snap ring has a tab or loop on its periphery, allowing the device to be removed from the PAPR hood after being adhered. In some embodiments, the snap ring and gel pad are single-use. FIG. 32 depicts a rear view of an exemplary embodiment.

[0205] In some embodiments, a PAPR hood may cover the user's head and make it difficult for the wearer to hear third-party voices. In such embodiments, it may be advantageous for communication devices and systems to include a second speaker for installation inside the PAPR hood. FIG. 33 depicts an exemplary embodiment having a communication device (shown mounted inside the window, but which may be positioned anywhere within the PAPR hood) operably connected to an additional speaker located within the PAPR hood. The device in FIG. 33 depicts a microphone housing with a microphone for picking up user speech on the exterior of the PAPR hood window connected to the speaker housing. 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 may also include an additional microphone to pick up speech (such as speech from third parties) from outside the PAPR hood. Speech from the additional microphone may be projected by the speaker located within the PAPR hood so that the user can clearly hear the third-party speech. In an alternative embodiment, a single unit is placed inside the PAPR hood that houses a microphone for picking up user speech and a speaker for playing third-party speech (picked up by a second microphone outside the hood). In a further alternative embodiment, two units are placed inside the PAPR hood, one housing a microphone for picking up user speech and the other housing a speaker for playing third-party speech (picked up by a second microphone outside the hood).

[0206] In another embodiment, a hook and loop attachment may be utilized to releasably attach the communications device housing to a mask, such as a disposable face mask. In some embodiments, the hook and loop attachment is associated with the communications device housing (such as a microphone housing), and the hook attachment is configured to engage an exterior surface of the disposable face mask. Alternatively, the face mask or PAPR hood may include a loop surface for the hook and loop connection, or may include a substantially rough and textured surface for the attachment of the hook and loop connector. Other types of associated releasable connectors are also contemplated, including any connectors having an array of protrusions that interfere with mating of the connectors, such as any Velcro®-type connectors known in the art.

[0207] In some embodiments, a microphone module associated with a user's mask or PAPR hood wirelessly communicates with a speaker module and / or a user computing device, such as a computer, tablet, mobile smartphone, or other module with communications capabilities. Generally, any communications protocol is useful, including RF, Wi-Fi, Bluetooth, 5G, other cellular protocols, etc. In some embodiments, the microphone module can be docked into the speaker module for storage and / or charging. In some embodiments, the microphone and speaker modules, separately or together, are docked into an additional module that supports storage, charging, and / or sterilization of one or more communications devices.

[0208] In some embodiments, a docking station is provided for any of the communication devices described herein. An exemplary docking station is depicted in FIGS. 34-35. In the depicted embodiment, the speaker housing (or speaker module) has a clip for attachment to a respirator hose (fluid delivery tube, respirator hose, PAPR hood tube, etc.). The docking station may include multiple posts for engagement with the clips or other connectors on the speaker housing. In the engaged position, the speaker housing may be charged via a wired or wireless charging connection. In some embodiments, the docking station includes approximately 1-20 posts, or approximately 1-10 posts, or approximately 2-9 posts. In some embodiments, the docking station includes two posts. In some embodiments, the docking station includes five 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 irradiate substantially all surfaces of the speaker housing. Advantageously, the post also houses UV lighting to illuminate the back of the module and clip, ensuring substantial disinfection. In some embodiments, the microphone housing and wires (or alternatively, the microphone module in wireless embodiments) may also be retained within the docking station. In another embodiment, the microphone housing and wires may be removed prior to docking.

[0209] The 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 sterilizer further includes a UV-blocking lid or cover, the interior surface of which is reflective and reflects the disinfecting UV light onto the contained module. By using a lid to cover the unit, the disinfecting UV-C is contained within the unit and is not substantially transmitted outside the unit for user safety. In some embodiments, the UV sterilizer includes a safety feature, such as a button or interlock, so that the UV sterilizer will not emit UV-C until the lid is in place. In some embodiments, the UV-C sterilizer further includes wireless capability to interface with a user's mobile device, computer, or smartphone to control one or more functions of the sterilizer or schedule the disinfection process. In some embodiments, the sterilizer includes a timer, sensor, or combination thereof to set the appropriate activation time for disinfecting the contained device.

[0210] In some embodiments, the speaker housing has alternative mechanisms such as a pocket clip attachment, a magnetic attachment, a snap, or a button attachment. A docking station may be configured to accept the speaker housing shape and configuration and store, charge, and / or sterilize / disinfect the housing. In some embodiments, the docking station may include a wired charging connection such as micro USB, USB-C, Lightning, or other charging interfaces such as a spring contact interface. In some embodiments, such a docking station has multiple docking features that partially or substantially surround the shape of the speaker housing and securely position the housing for charging. In some embodiments, the docking features and base of the docking station are UV-transparent, allowing UV light to be generated inside the station.

[0211] The UV disinfection station may have a lid that is merely reflective, or the lid may further include an LED or other UV-C light source to irradiate contained devices with disinfecting UV-C light. In some embodiments, the lid is removable from the disinfection station. In another embodiment, the lid may be hingedly attached to the disinfection station. In some embodiments, power may be supplied to the UV-C light source in the hood by a wire extending through the hinge, if applicable, or by contacts (such as spring contacts or other electrical contacts) that connect only in the closed position. In some embodiments, the contacts function both to power the lid UV-C light source and to act as an interlock such that the UV-C light will not power on unless the lid is in the closed position with the contacts engaged.

[0212] Clothing for medical professionals may also be designed to accept the speaker housing during use. For example, medical scrubs often have pockets, but they are large and may flex when an electronic unit is inserted. This poses a risk that the unit may fall out of the pocket while the medical professional is administering a procedure to a patient. The upper part of the scrub may be designed with a pocket, for example, configured to hold the speaker unit snugly against the user's torso. The pocket may generally be located over the user's chest area and may further have a zipper, snaps, buttons, or Velcro® to hold the pocket in a closed position while the speaker unit is housed. In some embodiments, the pocket is compatible with wired devices and accommodates a passage for a wire connecting the speaker housing to the microphone housing. The pocket, generally constructed from the same material as the clothing, may have one or more perforations or sound-transmitting panels to improve the projection of the user's voice. In further embodiments, the speaker module may take other forms useful or desirable in a medical setting. For example, medical professionals are already required to wear identification when administering treatment in a hospital setting. The ID speaker module may also be configured to hold any necessary identification cards for medical professionals. In an exemplary embodiment, as depicted in FIG. 36 , the ID speaker module may have a front panel that is transparent, allowing the identification card to be displayed. The front panel may be removable from the device, allowing the ID to be installed, or may be fixed in place, with the ID inserted through a slot on the side or bottom of the device. Generally, one or more speakers will face the same direction as the ID card. One or more speakers may be retained within the ID speaker module and may project sound through a perforation in the front of the device. In some embodiments, the ID speaker module further includes a transparent back panel for displaying additional identification or barcodes related to medication therapy or supply access.In another embodiment, the ID speaker module may clip to or include a ring for mounting on a medical professional's surgical gown or clothing. The ID speaker module may interface with an external microphone and / or speaker via a wired and / or wireless connection. In one embodiment, the ID speaker module may interface with other external devices, such as medical monitoring equipment or a nurse call light, and the module is 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.

[0213] Communication devices and systems are generally useful for a method of communication between a wearer and one or more third parties. In some embodiments, a method of communication by a mask or hood (such as a flexible face mask or PAPR hood) wearer may include securing a magnetically and releasably securable communication device to the mask or hood worn by the mask wearer, the communication device having a housing having a microphone configured to receive speech from the mask wearer as an audio signal, an attachment or attachment portion for securing the housing to the mask or hood, and a speaker operably connected to the microphone and configured to project the audio signal; receiving the audio signal by the microphone; transmitting the audio signal to the speaker; and projecting the audio signal by the speaker. In some embodiments, the attachment portion is magnetic. In some embodiments, the device includes a first magnetic attachment component and a second magnetic attachment component, the first magnetic attachment component associated with the rear surface of the housing, and a complementary second magnetic attachment component arranged to exert an attractive force on the first magnetic attachment component, releasably securing the rear surface of the housing to the mask. It will be appreciated that any of the described communication devices or systems may be utilized in a method of communication between a wearer and a third party. Such a method may include advantageous amplification or modulation of the wearer's voice to improve the quality of the communication.

[0214] FIG. 37 depicts an exemplary embodiment of a hood having a microphone releasably or permanently attached to the hood. During operation, a respirator or powered air filter connected to the hood by a supply tube can be loud, making it difficult for a third party to hear speech from the user. The microphone is positioned and configured to pick up speech from the user and project the speech from a speaker module or communication device / system. In an alternative embodiment, the microphone may be located in the coupler between the hood and the supply tube, or at any location along the supply tube. In a further embodiment, the respirator or powered air filter at the other end of the hood supply tube may have a built-in microphone to pick up speech from the user. Advantageously, it has been discovered that user speech travels well down the respirator hood supply tube to be captured within the tube or respirator unit. Speech picked up within the hood or mask, tube, and / or respirator unit may then be projected from any interfaced or external speaker, as described herein.

[0215] FIG. 38 depicts an exemplary embodiment of a communications device for use with a respiratory mask, such as an NIV mask, a CPAP mask, or a BiPAP mask, as further depicted in FIG. 35 . Such a device may include a spring-loaded clip configured and dimensioned to surround at least a portion of a fluid delivery tube or coupler to the respiratory mask. The spring-loaded clip may advantageously position a sound-transmitting portion of the communications device housing in proximity to the fluid delivery tube or coupler so that user speech is transmitted through the fluid delivery tube or coupler and through the sound-transmitting portion of the device housing to reach a microphone located on the rear portion of the housing. In some embodiments, the microphone located on the rear portion of the housing is the primary microphone for the device. Such a device 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 the microphone, as further depicted in FIGS. 31 and 32 . A second end of the cord may include a connector complementary to the connector on the communications device housing. In some embodiments, a connector at the second end of the cord screws onto the housing connector, forming a secure connection. In some embodiments, the microphone and cord are disposable. In some embodiments, the microphone and cord are reusable. The microphone housing is generally attached to the exterior surface of the respirator by clipping onto a snap ring, which is attached to the respirator by an adhesive pad. In some alternative embodiments, the first magnetic portion may be adhered to the respirator and the second magnetic portion may be coupled to or formed as part of the microphone housing.

[0216] The microphone located on the back of the communication device housing (i.e., the housing microphone) and the microphone housing at the second end of the cord (i.e., the corded microphone) may be used separately or together to pick up the user's speech. 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's speech can be maximized or optimized. Optionally, the front of the communication device may include a third microphone to pick up ambient or environmental noise for noise cancellation. As described herein, signals from the first, second, and third microphones may be used to generate an amplified speech signal for projection by a speaker located on the front of the housing behind the grill or a sound-transmitting portion on the front of the housing. Additionally or alternatively, the speech signal may be transmitted via Bluetooth® to an external device or speaker for amplification and / or playback.

[0217] In further embodiments, an application (i.e., software) running on the processor may include sound output features and device control features. Capturing speech through materials (such as mask materials) presents unique challenges not present in other sound amplification technologies. This is because each type of mask has a unique transfer function that affects the mask wearer's speech. These transfer functions will affect or degrade the characteristics of the user's speech, including loudness, frequency response / spectral balance, and timbre / distortion. Thus, to a third party, the mask wearer's speech will not only sound muffled, but will also sound different from their normal voice depending on the intervening mask material, which will alter the transmission of different frequency components of the user's speech.

[0218] Recognizing this unique challenge, the present disclosure further provides applications that include profile features. Respiratory masks from different manufacturers and different models of masks from the same manufacturer may have different shapes and constructions (materials, material thicknesses, etc.), meaning they will have unique sound transmission characteristics. To correct for the mask wearer's speech, which is altered by the mask, the profile features include one or more profiles that correct the user's speech to approximate the frequency and magnitude characteristics of normal speech without a mask.

[0219] FIG. 39 depicts an audio spectrum showing sound pressure level (SPL; y-axis), i.e., magnitude, as a function of frequency (x-axis, logarithmic scale) from 100 Hz to 20 kHz. The figure 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. From the spectra, it can be seen that the amplified signals overlap well with each other and approximate the spectral shape of normal speech levels across most of the spectrum. As a result, the amplified speech projected by the communication device's speaker effectively and advantageously mimics the user's speech as if there were no intervening mask.

[0220] FIG. 40 depicts an exemplary comparison between the spectral response of speech through a cloth mask when a communication device is on and off. The spectrum with the device on is generated using a mask-specific profile that amplifies frequency components damped by the mask. Further examples are provided for a soft plastic respirator (FIG. 41) and a hard plastic respirator (FIG. 42). Compared to the "off" spectral response, it is clear that different mask types have significantly different effects on the transmitted speech signal. In light of these differences, profiles may be developed that can compensate for the adverse effects that a mask has on the wearer's speech.

[0221] In some embodiments, the applications include one or more sound profiles each associated with a different type of face mask. In some embodiments, the applications include one or more sound profiles each associated with a different mask material (cloth, paper, fabric, soft plastic, hard plastic, etc.). In some embodiments, the applications include one or more sound profiles each associated with a different mask material and material thickness. In some embodiments, the applications include mask-specific profiles for mask models produced by major suppliers.

[0222] The profiles may be preloaded into the application or may be stored in the device's data storage or a cloud server for retrieval by the application. In one embodiment, the application runs on the processor of the communication device. In another embodiment, the application runs on the processor of a mobile computing device, such as a mobile phone, tablet, or laptop computer and mobile computing device that communicates with the communication device via a wireless communication protocol such as Bluetooth or WiFi.

[0223] The profile may be used to modulate audio within either the communication device or a wirelessly (optionally wired) connected mobile computing device. If the communication device modulates audio (i.e., user speech), the communication device may have non-transitory data storage, such as flash memory, for storing one or more profiles, and may have transient memory operable with the processor to modulate user speech audio for projection by the speaker. In an alternative embodiment, the speech signal may be transmitted to the mobile computing device for modulation according to a selected profile.

[0224] Profile settings on the communication device may be set in various ways. For example, the communication device may include several pre-loaded profiles, which may be set using buttons on the communication device. An LED indicator or audio played by a speaker may indicate to an operator (such as a user or hospital staff) which profile has been selected. For example, if 10 profiles are pre-loaded, the LED or speaker may indicate the current profile by flashing a certain number of times or playing "1, 2, 3..." or the like. In still further embodiments, the profile is selected within an application running on the processor of the mobile computing device. The profile may be one of several pre-loaded profiles on the communication device data storage, or may 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 may have additional storage for custom profiles that are not pre-loaded, so that the user may retrieve additional profiles from cloud storage.

[0225] Although an exemplary embodiment is depicted in FIG. 43 , variations of this exemplary embodiment should be considered. For example, a communication device 4300 as described herein is attached to a mask worn by a mask wearer. In some embodiments, 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-spoken audio through the mask material and any air gaps between the mask material and the microphone. One or more audio processing circuits 4304 are operatively connected to the one or more microphones. The audio processing circuit 4304 may, for some embodiments, include an analog-to-digital converter (ADC) and, optionally, a preamplifier. The audio processing circuit is operatively connected to a processor 4306, which may modulate the audio signal according to device settings, including profiles. A transient memory (not shown) may be operatively connected to the processor 4306 for performing processor functions. A data store 4310 may be operatively connected to the processor, the data store including one or more profiles. It should be understood that in an embodiment, non-transitory data store may be eliminated and transient memory may temporarily store profiles or aspects of profiles retrieved from linked mobile computing devices. However, to more clearly illustrate profile features, a data store will be described.

[0226] These various features, including the processor 4306, data storage device 4310, microphone, speaker, wireless communication circuitry, or any other circuit components, may be contained on one or more printed circuit boards (PCBs). Alternatively, the features may be incorporated into a chip. In various embodiments, the chip is programmable or may be programmed to perform the described features and functions in various associated communication devices.

[0227] The data storage device 4310 may include one or more pre-loaded profiles 4312. A "profile" may alternatively be referred to as a "speech output profile." In the exemplary embodiment of FIG. 43, three pre-loaded profiles 4312 are shown, although more or fewer profiles may be present. In some embodiments, there are no pre-loaded or default profiles, and only custom profiles are present. One or more custom profiles 4314 may optionally be stored in the data storage device or otherwise used by the communication device 4300. Custom profiles are generally not provided by the user, but rather are downloaded from a cloud server and associated with a certain material or type of mask. For example, when a manufacturer begins production of a new mask, a new profile may be optimized for the mask. The downloaded custom profile allows older communication devices to be compatible with the new mask. Advantageously, the communication device does not need to be updated with new firmware or hardware, as the profile will be compatible with both older and newer communication devices 4300.

[0228] Again, 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. For clarity, the selection is an internal device setting stored on transient or non-transient memory and not necessarily displayed on the screen. However, it is contemplated that some embodiments of the communication device may include a display screen. The configured profile may be read from the communication device in various manners. For example, the communication device 4300 may include an LED that flashes in response to a user prompt via a button on the device to indicate the configured profile. Alternatively, a speaker may audibly indicate the current profile setting by number, or by an assigned name or any other identifying indicia. Identifying the configured profile via the device is not necessary in all embodiments, as applications running on the mobile computing device may be used to display and select related information, as described further below.

[0229] The communication device 4300 will generally include wireless communication circuitry 4308 for connecting the communication device 4300 to the 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 understood by one skilled in the art. The 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 generally displays information to a user or medical professional, including the connection status to the communication device 4300 and the selected current profile. The profile 4362 displayed in the application 4360 generally corresponds to a profile on the communication device 4300. The mobile communication device 4350 and the communication device 4300 may undergo a synchronization procedure so that the mobile computing device 4350 can display a profile loaded on the communication device 4300. For purposes of example, the GUI may display profile 4362 as well as other profiles on the communication device that are not currently loaded on or usable by the communication device. If the user selects a profile that does not exist 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 preset number of custom profile slots, and one or more custom profiles may be deleted when a profile slot is full and a new custom profile is uploaded. The application 4360 may additionally display a "cloud profile" 4364 to the user or operator. The cloud profile 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 they are downloaded for use by the system. In other words, cloud profile X, if downloaded, may be added as custom profile C or may replace custom profile A or B, depending on user preference. In this way, updated profiles may be obtained on the fly by the user as long as an internet connection exists.

[0230] The communications 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 would be expected to be encountered in a hospital or medical setting. In this way, a profile with acceptable sound quality can be selected even in situations where internet access is unavailable.

[0231] In still further embodiments, the application may have a feature that allows a custom profile to be generated using a particular mask or face covering. For example, the mobile computing device may prompt the wearer to speak a sentence, and the mobile computing device's microphone may detect the frequency components of the user's speech with the communication device on or off. Alternatively, an experienced user may adjust one or more parameters of a given profile in an expert mode of the application 4360 to optimize sound quality.

[0232] The profile 4362 may include further instructions for display to a user or operator via a GUI. For example, for a particular mask, 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 then instruct the operator to place the microphones 4302 in similar or identical positions on the mask for optimized collection of the user's speech. Alternatively, the microphones 4302 may be placed according to general instructions. In still further embodiments, the application 4360 may include a placement optimization feature that instructs the user to reposition one or more microphones 4302 if the sound quality (i.e., the frequency spectrum of the projected speech) deviates from an expected spectral profile.

[0233] In various embodiments, the "profile," alternatively referred to as a "speech output profile," may compensate for frequency-dependent transmission losses of the user's speech through the mask. In conjunction with the examples provided, the devices, systems, and methods herein advantageously solve the identified technical problem that different masks have significantly different spectral or frequency-dependent sound transmission profiles. Compensating for these differences is important for more accurately projecting output sound that sounds like the user's voice. Particularly in the final moments of life, when many patients may need to wear respiratory masks, or in emergency situations where a protective mask or hood is required, it is important that the user's voice be identifiable by loved ones or other concerned parties. In this context, "compensating" means that the output speech will approximate the user's speech in terms of audio spectrum (frequency), rather than necessarily exactly matching the user's speech without the mask. Additionally, "compensate" does not necessarily mean that the amplitude or volume exactly matches the user's speech without masking, but may be similar or greater depending on the desired amplification level (volume), which may be adjustable by a connected application on the communication device or mobile computing device. Amplification of the sound signal or sound data may be performed at various stages, such as after collection of the sound by a microphone but before conversion to a digital signal, after conversion to a digital signal but before modulation, after modulation, or at the speaker amplification / speaker projection stage. These are exemplary, and analog devices are also generally considered. It is also possible that amplification occurs at some stage within the device function (e.g., microphone preamplifier), while the speaker volume may still be set to a volume lower than normal speech level.

[0234] In a general sense, amplifying a speech signal or speech data involves changing the amplitude of essentially all of its frequency components, while modulating a speech signal or speech data involves changing the amplitude of less than essentially all of its frequency components (e.g., changing the amplitude of only some frequency components). Advantageously, the profile or sound output profile of the present disclosure provides for adjustment of certain frequency components of the speech signal or speech data depending on the mask construction material or mask design (model number, size, type, etc.). Additionally, in many embodiments, the communication device may include microphones located near the fluid delivery tube or connection to the mask, as well as microphones located on the exterior surface of the mask; in such cases, the sound output profile may be optimized for speech signals or data from microphones at these locations. In some embodiments, the sound output profile is optimized for microphone configurations (devices with one microphone, two microphones, etc.), including similar microphone placements. It should be understood that individual sound output profiles for any relevant device disclosed herein are contemplated. Additionally, it should be understood that various aspects of the profile may be contained on or invoked 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.

[0235] In further embodiments, artificial intelligence or machine learning is used to generate or optimize one or more profiles. In some embodiments, artificial intelligence is used to generate or optimize one or more profiles using one or more inputs selected from the number of microphones, microphone locations, mask material, mask manufacturer, mask manufacturer model number, patient age, patient gender, patient medical history, patient speech samples from different audio devices, patient speech samples from communication devices, patient speech samples with profiles or filters applied, or any other useful input data. Accordingly, in further embodiments, methods are provided for training a machine learning algorithm that includes one or more such inputs, and for optimizing speech profiles using the trained machine learning algorithm. Also provided are devices and systems that include or utilize machine learning to generate or optimize profiles.

[0236] The mobile computing device application may perform other functions, including audio recording 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 the mobile computing device for recording and / or transcription. Optionally, a profile may be applied to the recorded audio signal so that it most closely resembles the unbuffered sound of the speaker. Additionally, the profile may be utilized to optimize the audio signal for improved recognition by a transcription program or feature. Transcription may be performed by a built-in 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 may be displayed on the mobile computing device or other display, allowing the patient to communicate with a hearing-impaired third party.

[0237] In various embodiments, a communication device of the present disclosure may include a housing having or including one or more microphones. The microphone may be built into the housing or located near a sound-transmitting portion thereof. It is contemplated that the sound-transmitting portion may be an access hole that allows sound to reach the microphone, and the microphone may be mounted within such a sound-transmitting portion. The sound-transmitting portion of the housing may also include a grill made of the same or a 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 air or fluid transmission, but which effectively transmits sound. In some alternative embodiments, if the housing is constructed from a material that properly transmits sound, the sound-transmitting portion may be a portion of the housing body near which a microphone is mounted to capture sound transmitted through the housing. In various embodiments, the sound-transmitting portion may be located relative to or in proximity to a mask feature (such as the mask surface, the fluid delivery tube, or the junction between the mask and the fluid delivery tube). "Proximity" should be interpreted as being close enough to collect user utterances for operation of the described communication device. In some cases, "proximity" may include one or more points of contact between the sound-transmitting portion (or alternatively, a portion of the microphone, if the microphone is disposed within 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 (e.g., within about 0.1-5 cm, or 0.1-2 cm, or 0.1-1 cm).

[0238] The communication device may also include sensors for detecting ambient or exhausted gas mixtures or temperatures. Monitoring gases and temperatures, such as air quality, can be useful in patient respiratory therapy, for first responders, or in any scenario where a user requires a mask. The device may include a separate membrane or filter used to sample or analyze ambient or exhausted air quality for pollutants, particulates, or pathogens in real time. The membrane may be removable, replaceable, or washable. Sensors within the device may include relative or absolute humidity sensors, temperature sensors, dew point sensors, enthalpy sensors, pressure sensors, barometric pressure sensors, flow sensors, oxygen sensors, carbon monoxide or dioxide sensors, nitrogen sensors, or combinations thereof. Sensors may detect or monitor characteristics not associated with air quality, and these sensors may include acoustic sensors, light sensors, cameras, ambient temperature sensors, accelerometers, or any sensor related to the exhausted or ambient environment. It is also envisioned that sensors may be external to the device but connected to ports on one or both of the inner or outer housings.

[0239] In operation, the device may detect the user's voice or sounds via a microphone and reproduce the sounds via a speaker. The device may include a microphone, speaker, processor, battery (disposable or rechargeable), charging / data port, communications such as Bluetooth®, volume control, light, light-emitting display (LED), camera, video screen, and a measurement port with the capability to electronically measure breath (and / or vapors exiting the user's mouth), noise, speech, tone, etc. The microphone may be noise-canceling. The device may provide communication between the inner and outer elements and any external system via any wired or wireless connection such as RFID, WiFi, Bluetooth®, Zigbee®, Zwave, 2G, 3G, 4G, 5G, or any reasonable later-developed wireless modality.

[0240] The device may also include a feedback unit for the user, such as headphones or in-ear components. 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 ears. The feedback unit may be sized and configured to include additional microphones elsewhere around the user, such as at the user's throat. The feedback unit may be useful in masks, helmets, or other items that cover or insulate the user's head.

[0241] It is contemplated that the device may include any other reasonable technology, system, or process to assist in communication between the user and others. These technologies include microprocessors, microcontrollers, computer chips, programmable algorithms for processing device data (including sound), any components for capturing sound and human voices, speakers and any technology used to project sound and human voices, noise cancellation technology, wireless capabilities for communication between microphones and speakers and between the device and remote devices such as external speakers, portable / cell phones, watches, computers, and televisions. The device may also include voice enhancement technology and voice recognition / voice playback technology and voice command technology, such as those found in personal digital assistants such as Amazon® Alexa®. The device may also include machine learning and other programming code that will learn the user's voice and optimize the system for that voice or play sounds within the user's voice. Machine learning or artificial intelligence (AI) may be utilized to provide, support, or optimize various functions of the disclosed devices, systems, and methods. For example, machine learning or AI may be utilized to optimize inputs and outputs into and out of a communication device. AI-based speech translation may be implemented on a built-in communication device, a connected mobile computing device, or a cloud computer. In some embodiments, optimized audio from a speech output profile may be utilized as input for speech translation or AI-based speech translation. In particular, for AI speech translation, it may be advantageous to use optimized audio from a speech output profile that preserves one or more sound characteristics of a user's speech. For example, AI speech translation may provide amplitude matching at one or more frequencies of the user's speech spectrum, meaning that the amplitude of the profile-corrected untranslated speech and the translated speech may be approximately matched to one or more frequencies of the user's speech spectrum.

[0242] The wearer's speech may be translated into a third-party language by a translation service such as Amazon Translate, Google Cloud Translate, or Microsoft Translator, among others. Alternatively, the communication device may include all necessary hardware and / or software to perform built-in speech translation in real time, with minimal delay (i.e., about 0.5 seconds or less to about 5 seconds) between the spoken words and the projected translation. An application running on the smartphone may interface with the communication device and system to change or implement any described settings or features. In further embodiments, other functionality performed by the communication device itself, an external computing device such as a smartphone or computer, and / or a cloud computer includes speech translation, speech transcription, accent translation, and / or speech recording. Voice recording and / or transcription embodiments may interface with local or cloud storage devices to store speech audio and / or transcribe words spoken by the user into text, respectively. Such embodiments may be advantageously used for medical records or to record any other user speech. The sound may be increased in volume based on the device settings and sound processing within the unit. The sound may be modified, such as via an electronic sound synthesizer or similar technology. The device may include hardware or software acoustic filters within the device that may filter out non-human sound range sounds.

[0243] In still further embodiments, one or more components may be located within a positive pressure device (such as a BiPAP or CPAP device fluidly coupled to a respirator mask by a fluid delivery tube). For example, it has been discovered that sound traveling from the respiratory mask through the fluid delivery tube to the positive pressure device can be captured by a microphone within the positive pressure device for effective amplification, as described herein, or for other features such as transcription, recording, translation, etc. For example, FIG. 44A depicts a respiratory mask 4400a coupled with a fluid delivery tube 4410a. The fluid delivery tube, shown with a dashed line, connects continuously from the mask 4400a to the positive pressure device 4450a. In an exemplary embodiment, a microphone 4420a is provided within or associated with the positive pressure device 4450a. For example, the microphone 4420a may be located within or near a fluid cavity within the positive pressure device 4450a, or may be separated from the fluid cavity by a sound-transmitting 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, a processor, a speaker, wireless networking components, etc., as described herein. For example, in an embodiment, the positive pressure device 4450a may include audio processing capabilities and then either play the amplified speech from an integrated speaker or transmit the amplified speech to another device or speaker. In another embodiment, the positive pressure device 4450a may transmit raw or processed audio signals to another device, such as a mobile computing device, for processing / playback. It may be understood that the positive pressure device 4450a may include any features associated with the concept of capturing user speech by the microphone of the positive pressure device 4450a.

[0244] Alternatively, or in addition, 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 positive pressure device 4450b without a microphone itself, it is contemplated that additional microphones may be present in the positive pressure device in addition to the one or more microphones associated with the respiratory mask. When one or more microphones 4420b or 4420c are associated with the respiratory mask or its fluid delivery tubing coupling portion as taught herein, they may be connected to the positive pressure device by one or more wires 4425. Alternatively, one or more of the microphones are connected wirelessly to positive pressure device 4450b. Similar to the example of FIG. 44A, positive pressure device 4450b may include an optional audio component 4430b to process user speech from the microphones or transmit raw or processed user speech signals to an external device. It is also contemplated that the positive pressure devices (4450a, 4450b) may include selectable speech output profiles as taught herein. The speech output profiles may take into account mask material type, manufacturer, and manufacturer model number, and may further take into account aspects of the fluid delivery tubing (length, inner diameter, material, manufacturer, and / or manufacturer model number) and the positive pressure device (model, positive pressure device settings, etc.). Accordingly, various positive pressure ventilation systems are contemplated, including speech amplification by one or more microphones on the respiratory mask and / or positive pressure device, as taught herein. In still further embodiments, one or more microphones may be located along or attached to the exterior of the fluid delivery tubing at a location between the respiratory mask and the positive pressure device.
