[0006] not applicable. Background Art

[0007] In hazardous environments, first responders (such as firefighters) often wear masks, such as with SCBAs. In such hazardous environments, vision may often be obscured, for example, by smoke. This visual impairment may make it difficult for a firefighter to operate (e.g., because the firefighter may have difficulty seeing to locate a fire and / or persons in need of assistance and / or other firefighter / responder personnel), and may even make it difficult for a firefighter to use various instruments / equipment that may be carried or used by the firefighter (e.g., because the screen or controls of the equipment are obscured, for example, by smoke). Summary of the invention

[0008] In embodiments, a mask embodiment may include a breathing air system configured to provide breathing air to a user; an eyepiece configured to protect the eyes and face of a user; a camera located on a portion of the mask and configured to capture data of a user in proximity to the user; a near-eye display located on an interior of the eyepiece and configured to display information to the user near the user's face; and an electronic module attached to the eyepiece and configured to power and control the near-eye display, receive information from one or more devices, and display the received information via the near-eye display.

[0009] In an embodiment, a near-eye display (e.g., for use with a mask) may include a display located on an interior lining of the mask and configured to provide information to a user; and an electronic module configured to receive information and display the received information via the display, wherein the electronic module includes a wireless communication module.

[0010] In embodiments, a method (e.g., for displaying information to a user wearing a mask) may include receiving information from one or more devices carried by the user or located near the user; displaying the received information via a near-eye display located on an interior lining of the mask; and switching between multiple displays on the near-eye display based on input from the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] For a more complete understanding of the present disclosure, reference is now made to the following brief description considered in conjunction with the accompanying drawings and detailed description, wherein like reference numerals represent like parts.

[0015] Figures 3A-3C Illustrated are exemplary gesture-based controls for use with a respirator mask including a near-eye display in accordance with an embodiment of the present disclosure. DETAILED DESCRIPTION

[0016] It should be understood at the outset that although illustrative implementations of one or more embodiments are described below, the disclosed systems and methods may be implemented using any number of techniques, whether currently known or not yet in existence. The present disclosure should in no way be limited to the illustrative implementations, drawings, and techniques described below, but may be modified within the full scope of the appended claims along with their equivalents.

[0017] The following brief definitions of terms should apply throughout this application:

[0018] The term "including" means including but not limited to, and should be interpreted in the manner in which it is typically used in a patent context;

[0019] The phrases "in one embodiment," "according to one embodiment," and the like generally mean that a particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the invention, and may be included in more than one embodiment of the invention (importantly, such phrases do not necessarily refer to the same embodiment);

[0020] If the specification describes something as "exemplary" or an "example," it should be understood to refer to a non-exclusive example;

[0021] When used with a number, the terms "about" or "approximately" and the like can mean the specific number, or, alternatively, a range around the specific number, as understood by one skilled in the art (e.g., + / - 10%); and

[0022] If the specification states that a component or feature "may", "could", "might", "should", "will", "preferably", "likely", "typically", "optionally", "for example", "often", or "might" (or other such language) be included or have a characteristic, then it is not required that the particular component or feature be included or have that characteristic. Such a component or feature may optionally be included in some embodiments, or it may be excluded.

[0023] Embodiments of the present disclosure include systems and methods for providing improved vision to first responders when working in hazardous environments. For protection while working in hazardous environments, firefighters may wear / carry a self-contained breathing apparatus (SCBA) that may also include a personal safety alarm system (PASS) to indicate certain characteristics or conditions of the environment, the user, and / or equipment carried by the user. It may be important for the user to be able to see status information conveyed by the PASS, but when working in a hazardous environment (such as fighting a fire), smoke may quickly degrade the user's vision, essentially rendering the firefighter "invisible" and hampering their ability to effectively perform, locate the fire, and / or locate victims.

[0024] To help locate certain parts of the fire while having limited vision, firefighters can use handheld thermal imaging cameras (TICs) to supplement their vision through the smoke-filled environment. Additionally, firefighters can wear a heads-up display (HUD) configured to provide information such as instrument status, environmental characteristics, and audible and visible alerts to understand the status of the PASS.

[0025] In order to operate the PASS, TIC, and / or HUD, the user may be required to provide physical feedback or action, such as holding the TIC, pressing one or more buttons. However, depending on the protective equipment worn by the user and environmental factors, physical interaction with the equipment may be difficult. Typically, there is no hands-free operation option for using the PASS, TIC, and / or HUD. Some TICs may be available for firefighting use in helmet-mounted units, where the display is located outside the helmet, but smoke-filled environments may obscure or obscure the view of the display (making use / manipulation more difficult or impossible). Typically, the TIC may not be configured to connect to the PASS, and therefore, TIC data may not be included in the information communicated to the user via the HUD, such as the status or health of the PASS.

[0026] By integrating a digital heads-up near-eye display into the face mask of a SCBA, embodiments of the present disclosure provide a hands-free solution for providing an enhanced view (including information about the surrounding environment) to the user. The near-eye display can be connected with other devices carried / worn by the user and can be able to provide information to the user regardless of impaired visibility due to the environment (e.g., because the display is located within the mask, such as via the near-eye display). Additionally, the near-eye display can be configured to receive and display information from a TIC mounted on the face mask.

[0027] To allow hands-free operation of a near-eye display and / or an instrument / device that communicates with and / or is controlled by a near-eye display system (e.g., an instrument / device whose information is to be displayed by a near-eye display), a camera (e.g., a system with a camera) (which may be a TIC) may be configured with gesture sensing, wherein gestures may control a graphical display of the near-eye display. The graphical display may include current system status or health, such as cylinder pressure, battery status, system faults, and / or other diagnostics, as well as user biometrics, environmental characteristics, and any other information that may be communicated to the near-eye display from one or more devices carried or worn by the user. The near-eye display and gesture sensing may allow two-way communication with the PASS system, wherein gestures may indicate and cause the display to switch between modes. Gesture sensing may be preferred over other hands-free options, as voice recognition and communication may be difficult when wearing a mask. The near-eye display may include a wireless or wired connection to the SCBA, PASS, TIC, or any other device / instrument carried or worn by the user. Additionally, the near-eye display can communicate wirelessly with devices within the environment (e.g., devices not worn by the user but typically in the vicinity of the user (e.g., in the same environmental area)), such as local detector devices, drone devices, etc. In some embodiments, the near-eye display can be used with only one of the devices (e.g., a thermal imaging system that is not connected to the PASS).

[0028] The near-eye display may be mounted inside a typical mask or helmet (e.g., of an SCBA system) to provide uninterrupted communication to the user. The near-eye display may be battery operated and configured to be attached to a portion of the mask. The near-eye display may be adjustable by the user to improve comfort and visibility.

[0029] Now refer to Figure 1 , an exemplary embodiment of a respirator mask 100 is shown. The mask 100 may include a breathing air system 103, which may include seals, filters, valves, hoses and / or air supplies. In some embodiments, the breathing air system may include an oral / nasal cup 102 that is operable to cover the nose and mouth of a user. The cup 102 may be attached to one or more sleeves 112, wherein the sleeve 112 may be attached to an inhalation valve (not shown) on the cup 102. The sleeve 112 may filter the air breathed by the user. The cup 102 may also include an exhalation valve 110, wherein the exhaled breath of the user may be discharged through the exhalation valve 110. The cup 102 may be sealed to the user's face to ensure that the user breathes through the cup 102. In other embodiments, the cup 102 may not be sealed to the user's face, but may only guide the user's breathing.

[0030] In some embodiments, the mask 100 may include an eyepiece 104 (which may also be referred to as a mask or face shield) operable to protect the user's eyes and / or face. In some embodiments, the eyepiece 104 and / or the mouth / nose cup 102 may be attached to the frame 101, wherein the frame 101 may be held against the user's face by one or more head straps 106. In some embodiments, the frame 101 may seal against the user's face, preventing air from entering the interior of the mask 100. This may allow the user to breathe only through the inhalation valve(s) and the exhalation valve 110, and thus the user may also breathe filtered air through the sleeve 112.

[0031] In some embodiments, the cover 100 may include an electronics module 120 attached to the cover 100. In the illustrated embodiment, the module 120 may be attached to the eyepiece 104 of the cover 100. The cover 100 may also include a near-eye display 130 located on the inside of the eyepiece 104. The electronics module 120 may be located on the inside of the eyepiece 104 (or the cover) or on the outside of the eyepiece 104 (or the cover). The electronics module 120 may be connected (e.g., electrically, wired, wirelessly, and / or communicatively) to the near-eye display 130 to provide communication and / or power to the near-eye display 130.

[0032] The housing 100 may also include a camera 140, which may include an infrared (IR) camera or a thermal imaging camera (TIC). The camera 140 may be configured to provide information to the near-eye display 130 via a wired or wireless connection (e.g., be communicatively coupled to the near-eye display 130). The electronic module 120 may include a wireless communication module configured to provide communication between the near-eye display 130 and other devices, such as the camera 140 (e.g., such that the communicative coupling between the camera 140 and the near-eye display 130 may be through the electronic module 120), or any other device carried or worn by the user. In some embodiments, the camera 140 may be equipped with gesture sensing, wherein the sensed gesture may control the display of the near-eye display 130 (e.g., allowing the user to switch / scroll between different devices / instruments using a gesture (e.g., a first gesture)) and / or select one of several devices / instruments for display on the near-eye display (e.g., display of information of the selected device) using a gesture (e.g., using a second gesture). In some embodiments, the camera 140 (e.g., TIC), the electronic module 120, and the near-eye display 130 may work together for gesture control (e.g., as part of a system). For example, the camera 140 may detect user hand motion, the electronic module 120 may analyze data from the camera 140 to determine whether the detected hand motion / gesture matches a predefined gesture indicating a pre-set control, and the near-eye display 130 may operate in accordance with the control (e.g., when a match is detected / occurs).

[0033] Figure 2A-2B Additional views of an exemplary mask 100 including a camera 140 , an electronics module 120 , and a near-eye display 130 are illustrated. Figure 2A A front view of the housing 100 is shown, and Figure 2B A rear / interior view of the mask 100 is shown. In some embodiments, the mask 100 can be connected to a hose or other air supply, and the mask 100 can include a vent valve 110.

[0034] Figures 3A-3CAn example of a gesture-controlled display for a near-eye display 130 (as shown above) is illustrated. The gesture-controlled display 300 may include multiple "displays," which may also be referred to as screens or menus. The display may include, but is not limited to, temperature 302, gas sensor readings 304, drone view camera 306, vital organs (or user biometrics) 308, thermal view 310 (which may be provided by the TIC), heads-up display 312 (which may include information from the PASS), and / or navigation 314 (e.g., for selecting and displaying information from various devices that may communicate with the system). The displays described herein are examples only, where other information (e.g., additional and / or alternative information) may be included in a system that may be used for a near-eye display. In some embodiments, the electronic module may be configured to receive gesture information from a camera and control the display of the near-eye display accordingly.

[0035] Figure 3B and 3C Examples of gestures that can be used to control near-eye displays are illustrated. Movement of a user's hand in front of the camera can indicate different actions. For example, a back-and-forth movement, such as a wave or swipe 320, can indicate that the user wants to move between displays (e.g., between displays associated with different devices, such as Figure 3A As another example, the thumb lift 322 movement may indicate that the user wants to select the current option (e.g., move between displays (e.g., Figure 3A In order to select a specific device from multiple devices). Additionally, other movements of the user's hand can be associated with actions on the near-eye display. Thus, the user may wave / swipe his hand (e.g., within a certain range or position or spatial window) to move or rotate between available displays (e.g., each of which is associated with a specific device from multiple devices that are communicatively coupled to the system and / or can be used to provide information for display in the system), and may give a thumbs-up hand gesture (e.g., within the spatial window) to select the current or active display. The near-eye display may then display information associated with the selected display and / or information received from a corresponding device associated with the selected display.

[0036] Some embodiments may also include a method (which, for example, may be performed / implemented by a mask system of the type described herein) comprising one or more of the following steps: detecting hand movements / gestures of a user / wearer of the mask by a camera (e.g., a thermal imaging camera) (e.g., where the TIC / camera is configured to detect hand movements / gestures of the user / wearer (e.g., within a designated spatial window in front of the user)); transmitting image / motion / gesture data from the camera (e.g., the TIC) to an electronic module (which typically includes a processor configured to evaluate such data and communicate with the TIC); evaluating the image / motion / gesture data by the electronic module (e.g., in communication with the TIC) to determine whether one or more predetermined control motions / gestures are detected (e.g., by comparing with pre-set control image / motion / gesture criteria); in response to determining that the image / motion / gesture data corresponds to a predetermined control motion / gesture, According to a control image / motion / gesture standard, display image information is transmitted to a near-eye display based on the detected control data by an electronic module; the display image information is displayed by a near-eye display (e.g., in a cover), wherein the control image / motion / gesture standard includes at least two different image / motion / gesture standards (e.g., corresponding to (a) switching / scrolling between displays (which may each involve different devices / instruments that can receive and display data from them) and (b) selecting a display (e.g., associated with one of the different devices) - for example, using a hand wave / swipe and a thumb lift); and scrolling / switching between displays based on a first preset hand motion / gesture and selecting based on a second preset hand motion / gesture by an electronic module and a near-eye display (e.g., associated with various devices / instruments and operable or configured to communicate with the system).

[0037] In some embodiments, the method may include communicatively coupling a plurality of devices to an electronic module (e.g., wirelessly) such that the electronic module may receive information / data from each of the devices (e.g., selectively (e.g., on different channels)) or each (e.g., simultaneously (e.g., using a single channel)) (such that in some embodiments, the electronic module determines which device to receive from (e.g., switches to a channel associated with that device) and then transmits the information to a display, and in other embodiments, the electronic module may continually receive information from all (or at least multiple) devices (which may all transmit on a single channel) and then internally decide which information to send to the display); providing a display associated with each device for scrolling purposes; providing a display associated with a selected device for display of actual received data / information from the selected device. In some embodiments, the system further includes a PASS configured to communicate with the plurality of devices, and the electronic module communicates with one or more of the devices via the PASS. In some embodiments, one of the devices is a drone configured to transmit image data (e.g., thermal images) from a different perspective / vantage point / angle than the user / TIC (e.g., to the electronic module). In some embodiments, the method also includes attaching the TIC, electronics module, and near-eye display to a pre-existing SCBA mask (e.g., mounting the TIC and electronics module on the mask and mounting the near-eye display within the mask (e.g., on the interior of the mask / eyepiece)); transmitting data from the electronics module to one or more of the devices, wherein the electronics module includes a wireless receiver / transceiver; and / or using thermal imaging (e.g., the TIC) to detect user hand movements / gestures (e.g., within a smoke environment so that the control mechanism will not be affected by the smoke).
