Abstract:
Various embodiments associated with a heads-up display capable of functioning while underwater are described. An underwater mask can have a segment that a diver sees through and this segmented can be augmented with various portions that disclose information to the diver. These portions can relate to the diver herself or relate to other information such as the location of a source transmitting a signal. With these portions the diver can quickly learn about important information and act on that information.

     BACKGROUND 
       [0002]    To dive underwater, a diver may employ different pieces of equipment. One example piece of equipment can be a breathing apparatus that includes an oxygen tank, hoses, and a mouthpiece. This breathing apparatus can enable the diver to stay underwater for a significant period of time. However, employment of the breathing apparatus can provide drawbacks. In one example, the driver cannot verbally communicate due to the mouthpiece and the fact that the diver is underwater. Therefore, communication for the diver while underwater can be limited. This can be a serious situation based on circumstances, such as when emergency circumstances occur. 
       SUMMARY 
       [0003]    In one embodiment, an underwater mask comprises an eyewear element and disclosure component. The eyewear element can be configured to be substantially transparent. The disclosure component can be configured to cause disclosure of a heads-up display upon the eyewear element while the eyewear element is submerged underwater. 
         [0004]    In one embodiment, a system comprises an access component, a configuration component, and a non-transitory computer-readable medium. The access component can access a data set that pertains to an underwater diver. The configuration component can configure a heads-up display in accordance with the data set, where the heads-up display, as configured, is disclosed upon an eyewear element of the underwater diver. The non-transitory computer-readable medium can retain at least one instruction associated with the access component, the configuration component, or a combination thereof. 
         [0005]    In one embodiment, a system comprises an access component, a configuration component, a disclosure component, and a housing. The access component can access a data set that pertains to an underwater diver. The configuration component can configure a heads-up display in accordance with the data set; where the heads-up display, as configured, is disclosed upon an eyewear element of the underwater diver.

     DETAILED DESCRIPTION 
       [0021]    In an underwater environment, communication among divers can be difficult especially over long ranges. To alleviate this problem, divers can be equipped with antennas that receive signals. The received signals can provide various types of information, such as directional information of a source of the signal. Once received, the signal can be processed and a heads-up display on a mask of a diver can provide information to the diver based on this processed signal. In one example, directional information relative to the diver can be presented on her heads-up display. 
         [0022]    The following includes definitions of selected terms employed herein. The definitions include various examples. The examples are not intended to be limiting. 
         [0023]    “One embodiment”, “an embodiment”, “one example”, “an example”, and so on, indicate that the embodiment(s) or example(s) can include a particular feature, structure, characteristic, property, or element, but that not every embodiment or example necessarily includes that particular feature, structure, characteristic, property or element. Furthermore, repeated use of the phrase “in one embodiment” may or may not refer to the same embodiment. 
         [0024]    “Computer-readable medium”, as used herein, refers to a medium that stores signals, instructions and/or data. Examples of a computer-readable medium include, but are not limited to, non-volatile media and volatile media. Non-volatile media may include, for example, optical disks, magnetic disks, and so on. Volatile media may include, for example, semiconductor memories, dynamic memory, and so on. Common forms of a computer-readable medium may include, but are not limited to, a floppy disk, a flexible disk, a hard disk, a magnetic tape, other magnetic medium, other optical medium, a Random Access Memory (RAM), a Read-Only Memory (ROM), a memory chip or card, a memory stick, and other media from which a computer, a processor or other electronic device can read. In one embodiment, the computer-readable medium is a non-transitory computer-readable medium. 
         [0025]    “Component”, as used herein, includes but is not limited to hardware, firmware, software stored on a computer-readable medium or in execution on a machine, and/or combinations of each to perform a function(s) or an action(s), and/or to cause a function or action from another component, method, and/or system. Component may include a software controlled microprocessor, a discrete component, an analog circuit, a digital circuit, a programmed logic device, a memory device containing instructions, and so on. Where multiple components are described, it may be possible to incorporate the multiple components into one physical component or conversely, where a single component is described, it may be possible to distribute that single component between multiple components. 
         [0026]    “Software”, as used herein, includes but is not limited to, one or more executable instructions stored on a computer-readable medium that cause a computer, processor, or other electronic device to perform functions, actions and/or behave in a desired manner. The instructions may be embodied in various forms including routines, algorithms, modules, methods, threads, and/or programs including separate applications or code from dynamically linked libraries. 
         [0027]      FIG. 1  illustrates one embodiment of an environment in which a receiver  110  receives a signal  120  from a source  130  that is processed by a processor unit  140 . The source  130  can emit the signal  120  that is received by the receiver  110 . In one example, the source  130  can be a piece of equipment of a diver and the signal  120  can be a distress signal that communicates positional information of the source  130 . The distress signal can be emitted by the diver by pressing a button, emitted when a condition is met (e.g., when the diver becomes unconscious determined by way of a biometric sensor), etc. In one example, the signal  120  can be a passive signal from which location and/or direction information can be ascertained. The source  130  can select a signal type (e.g., distress signal when an injury occurs, lost signal when a diver becomes disoriented on his location, etc.) and emit the signal  120  of that type. 
         [0028]    The receiver  110  can receive the signal  120 . Acoustic energy of the signal  120  can couple with an antenna array of the receiver  110  as part of this reception. The receiver  110  can be a hardware device that is a low-profile telescopic mast. In one example, the mast can be cylindrical that when fully-retracted can be about 4 inches and when fully-extended can be about 36 inches. With this example, the receiver  110  can have a pointer tip integrated with an antenna to receive the signal  120 . The pointer tip can obtain the signal  120  and the signal  120  can be transferred down a conductive surface of the mast and then sent to the processor unit  140  (e.g., that is separate from the receiver  110 , that is at least partially part of the receiver  110 , etc.). 
         [0029]      FIG. 2  illustrates one embodiment of a system  200  comprising a radio frequency power detector  210 , a voltage-to-frequency converter  220 , a frequency-to-voltage converter  230 , and a microcontroller unit  240 . In one embodiment, the processor unit  140  of  FIG. 1  can comprise at least part of the system  200 . The system  200  can be divided into two parts—a receiver portion  250  that can be integrated into a handle of the receiver  110  of  FIG. 1  and a body portion  260  that can be integrated into bodywear of the diver (e.g., integrated into a palm section of a wetsuit glove). 
         [0030]    The radio frequency power detector  210  and the voltage-to-frequency converter  220  can integrate into the receiver portion  250 . The signal  120  that is received by the receiver  110  of  FIG. 1  can be a radio frequency (time-variant) signal that is at a high frequency. The radio frequency power detector  210  (e.g., envelope broadband detector) can convert the signal  120  to a direct current (DC) signal  270  with a specific voltage value proportional an acoustic signal power input of the signal  120 . The voltage-to-frequency converter  220  can take the DC signal  270  with the specific voltage value and convert it to a time variant signal, but at a lower frequency than the initially received radio frequency to become the low frequency (LF) signal  280 . The receiver portion  250  can transmit the lower frequency time variant signal (LF signal  280 ) by way of a transmission coil to the body portion  260 . 
         [0031]    The body portion  260  can receive the lower frequency time variant signal (LF signal  270 ) by way of a pick-up coil. The frequency-to-voltage converter  230  can convert the lower frequency time variant signal (LF signal  270 ) back to the DC signal  270  with the specific voltage value. The microcontroller unit  240  can then process the DC signal  270  to identify the specific voltage value and then use the specific voltage value (e.g., to determine the location of the source  120  of  FIG. 1 ). As an alternative to the microcontroller unit  240  an analog unit can be employed in the body portion  260  to process the DC signal  270 . 
         [0032]    In one example, the signal  120  can indicate position information of the source  130  of  FIG. 1 . The specific voltage value selected by the radio frequency power detector  210  can correlate to the position information. The lower frequency time variant signal (LF signal  280 ) can directly correspond to the specific voltage value (e.g., determined by way of a look-up table) for use by the converters  220  and  230 . Therefore, by way of the specific voltage value, the microcontroller unit  240  can receive the correct position information. The microcontroller unit  240  can use the specific voltage value to communicate the position information of the source  130  of  FIG. 1  to the diver (e.g., by way of a mask of the diver). 
         [0033]      FIG. 3  illustrates one embodiment of a system  300  comprising a first conversion component  310 , a second conversion component  320 , and a transmitter  330 . The first conversion component  310  can be configured to convert a high frequency (HF) alternating current (AC) signal  340  (e.g., the signal  120  of  FIG. 1  as an acoustic location signal) to the DC signal  270 . A voltage value (e.g., the specific voltage value) of the DC signal  270  can correspond to a frequency value of the HF AC signal  340 . In one example, the radio frequency power detector  210  of  FIG. 2  functions as the first conversion component  310 . 
         [0034]    The second conversion component  320  can be configured to convert the DC signal  270  to a LF AC signal  350 . In one embodiment, this conversion can take place through use of a voltage control oscillator. The frequency value of the LF AC signal  350  can correspond to the voltage value of the DC signal  270 . Therefore, the LF AC signal  350  can communicate the same information as the HF AC signal  340 , but at a different frequency (at a lower frequency). In one embodiment, a look-up table can be employed for conversion between DC and AC by either or both of the conversion components  310  and  320 . In one embodiment, the voltage-to-frequency converter  220  of  FIG. 2  can function as the second conversion component  320 . 
         [0035]    The transmitter  330  (e.g., that is part of the voltage-to-frequency converter  220  of  FIG. 2 ) can be configured to transmit the LF AC signal  350  to a near-field receiver  360  (e.g., that is part of the frequency-to-voltage converter  230  of  FIG. 2 ). The first conversion component  310 , the second conversion component  320 , the transmitter  330 , the near-field receiver  360 , or a combination thereof can function while underwater and/or be resident upon a collection unit (e.g., the receiver  110  of  FIG. 1 ). In one example, the first conversion component  310 , the second conversion component  320 , and the transmitter  330  can be encompassed in the handle of the receiver  110  of  FIG. 1  while the near-field receiver  360  (e.g., the body portion  260  of  FIG. 2  that includes the near-field receiver  360 ) can be encased in a plastic capsule that is part of bodywear of a diver (e.g., attached to a part of a wetsuit). 
         [0036]    The transmitter  330  can employ a transmission coil to transmit the LF AC signal  350  to the near-field receiver  360 . The near-field receiver  360  can employ or be a reception coil to receive the LF AC signal  350  from the transmitter  330 . The transmission coil and reception coil can work inductively to communicate the LF AC  350  from the transmitter  330  to the near field receiver  360 . 
         [0037]      FIG. 4  illustrates one embodiment of a system  400  comprising the first conversion component  310 , the second conversion component  320 , the transmitter  330 , and a direction component  410 . The direction component can be configured to determine a direction of the source  130  of  FIG. 1  of the signal  120  of  FIG. 1 . This can be when the signal  120  of  FIG. 1  is the HF AC signal  340  of  FIG. 3 . The HF AC signal  340  of  FIG. 3  can communicate the direction of the source  130  of  FIG. 1 . This communication can be direct communication (e.g., expressly communicate the information) or be indirectly communicated such that the direction can be determined from signal information. 
         [0038]    The direction component  410  can determine the direction through various manners. In one example, the direction component  410  can be configured to determine the direction through time-direction of arrival analysis. In one example, the direction component  410  can be configured to determine the direction through omni-directional transpondence analysis. More detail regarding function of determining direction is addressed below with the discussion for  FIG. 8 . 
         [0039]      FIG. 5  illustrates one embodiment of a system  500  comprising the first conversion component  310 , the second conversion component  320 , the transmitter  330 , and a collection component  510 . The collection component  510  can be configured to collect the HF AC signal  340  of  FIG. 3  prior to conversion to the DC signal  270  of  FIG. 3 . Example type of collection can include actively obtaining the HF AC signal  340 , passively receiving the HF AC signal  340 , accessing the HF AC signal  340  from storage, etc. The collection component  510  can collect the HF AC signal from a repeater  610  discussed below and/or the source  130  of  FIG. 1 . 
         [0040]      FIG. 6  illustrates one embodiment of an environment  600  comprising the source  130 , the repeater  610 , and an obtainment unit  620 . The obtainment unit  620  can comprise the receiver  110  of  FIG. 1  and/or the processor unit  140  of  FIG. 1  (and in turn aspects of  FIGS. 2 and 3 ). The source  130  can be under a body of water with a water level of  630  and transmit the signal  120  that is of interest to the obtainment unit  620 . However, the obtainment component  620  may not receive the signal  120  directly from the source  130 . This can be due to various factors, such as an obstruction blocking direction communication between the source  130  and the obtainment unit  620  or the source  130  and obtainment unit  620  being configured to communicate directly with a central unit (e.g., the repeater  610 ). 
         [0041]    The repeater  610  can be a satellite or other object (e.g., communication device on an airplane) that propagates the signal  120  and/or produces the signal  120  (e.g., in response to instruction from the source  130 ). In one embodiment, the repeater  610  repeats the signal  120  from the source  130  to the obtainment unit  620 . In one embodiment, the source  130  sends the signal  120  in an encrypted manner so as to not have its content ascertained by an unintended force. The repeater  610  can decipher the signal  120 , re-encrypt the signal  120  (e.g., using the same encryption as from the source  130  to the repeater  610  or a different encryption), and send the signal  120  re-encrypted to the obtainment unit  620 . In one example, the source  130  can be of one military force while the obtainment unit  620  is of another friendly force. While the forces are friendly, they may not wish for the other to know their encryption algorithms and therefore the repeater  610  can function to mask encryption details from the forces. 
         [0042]      FIG. 7  illustrates one embodiment of a system  700  comprising a digital conversion component  710 , an analog conversion component  720 , and an emitter  730 . The digital conversion component  710  can convert the HF AC signal  340  (e.g., a distress signal) to the DC signal  270 . A voltage value of the DC signal  270  can correspond to a frequency value of the HF AC signal  340 . The frequency value indicates a direction of the source  130  of  FIG. 1  of the HF AC signal  340 . The analog conversion component  720  can convert the DC signal  270  to the LF AC signal  350 . A frequency value of the LF AC signal  350  can correspond to the voltage value of the DC signal  270  and thus in turn correspond to the frequency value of the HF AC signal  340 . 
         [0043]    The emitter  730  can emit the LF AC signal  350  to the near-field receiver  360  when the emitter  730  and the receiver  360  are underwater. The near-field receiver  360  can processes the LF AC signal  360  to determine the direction (e.g., the direction relative to the receiver  360 , the direction relative to a view position of a diver, etc.). The emitter  730  can employ an emission coil to emit the LF AC signal  350  to the near-field receiver  360  while the near-field receiver  360  can employ a reception coil to receive the LF AC signal  350  from the emitter  730 . The near-field receiver  360  can convert the LF AC signal  350  to the DC signal  270  and employ the DC signal  270  to determine the direction. The near-field receiver  360  of can be part of the body portion  260  of  FIG. 2  and can cause information based on the direction to be displayed by way of an underwater mask of the diver. 
         [0044]      FIG. 8  illustrates one embodiment of a system  800  comprising the digital conversion component  710 , the analog conversion component  720 , the emitter  730 , an acquisition component  810 , and a housing  820 . The acquisition component  810  can acquire the HF AC signal  340  of  FIG. 7 . Example implementations by which this acquisition of the acquisition component  810  can occur can be through radio frequency based monopulse beamforming (e.g., use of a single phase center antenna with an assumption of varying amplitude and constant phase) or phase monopulse beamforming (e.g., use of multiple antennas separated by a distance d with an assumption of varying phase and constant amplitude). The acquisition component  810  can use a sum-channel Σ and azimuth difference-channel Δ az  as part of beamforming. The difference-channel can indicate an azimuth direction of the signal  120  of  FIG. 1  while the sum-channel can indicate signal amplitude. For phase based monopulse beamforming a path length difference for the signal  120  of  FIG. 1  at azimuth angle θ to reach the receiver  110  of  FIG. 1  can be defined by ΔR=d sin(θ). The time-difference-of-arrival (TDOA) for the signal  120  of  FIG. 1  at an arriving angle θ off an antenna broadside can be defined as δT=d sin(θ)/c, where c is the speed of light (3×10 8  m/sec). Both amplitude and phase monopulse beamforming can measure the Δ az /Σ voltage ratio in order to estimate the error angle δ θ . Subsequently, this estimate can be used by the direction component  410  of  FIG. 4  to determine the direction of arrival for the signal  120  of  FIG. 1 . 
         [0045]    The housing  820  can retain the acquisition component  810 , the digital conversion component  710 , the analog conversion component  720 , the emitter  730 , at least one other component or other item (e.g., converter) disclosed herein, or a combination thereof. The housing  820  can be configured for use underwater such that a component retained by the housing  820  can function while underwater. The housing  820  can be of a shape for retention within the palm of a diving glove. In one example, the housing  820  can be a plastic handle of the receiver  110  of  FIG. 1  that can be gripped by the diving glove. The near-field receiver  360  of  FIG. 7  can be resident upon a diving glove. For the near-field receiver  360 , being resident on the diving glove can include being in a palm area, wrist area, finger area, thumb area, etc. 
         [0046]      FIG. 9  illustrates one embodiment of a system  900  comprising an eyewear element  910  and a disclosure component  920 . The system  900  can be part of an underwater mask that can be considered in at least some instances part of the body portion  260  of  FIG. 2 . Example underwater masks include a full-head mask, a full-face mask, an eye cover element (e.g., that does not cover nose or mouth), goggles, a SCUBA (self-controlled underwater breathing apparatus) mask, a mask appropriate for deep sea diving, or a mask appropriate for snorkeling. 
         [0047]    The mask can comprise the eyewear element  910  and the eyewear element  910  can be substantially transparent. In one example, the eyewear element  910  can be made of a plastic or other compound that can have information displayed such that a wearer can see through at least part of the eyewear element  910 , but the wearer can also be presented with information by way of the eyewear element  910 . The disclosure component  920  can be configured to cause disclosure of a heads-up display upon the eyewear element  910  while the eyewear element  910  is submerged underwater. The disclosure component  920  can be part of the mask in that it is part of a strap that keeps the mask on a head of the diver, the disclosure component  920  can physically connect to the eyewear element  910  to cause such disclosure, etc. In one embodiment, a housing (e.g., that is functionally equivalent to the housing  820  of  FIG. 8 ) can configured to retain the disclosure component  920  such that the disclosure component  920  functions without substantial adverse impact when submerged about 350 meter or less underwater. Thus, while underwater the eyewear element  910  can cause display of the heads-up display. 
         [0048]      FIG. 10  illustrates one embodiment of a heads-up display  1000 . The heads-up display  1000  is an example heads-up display that can be presented upon the eyewear element  910  of  FIG. 9 . The heads-up display  1000  can have various portions that communicate information while non-portion areas can allow a wearer to see outside of the eyewear element  910  of  FIG. 9 . While distinct portions are shown, it is to be appreciated by one of ordinary skill in the art that portions may not be distinct with one another, different portions can be active at different times, and that portions may overlap. 
         [0049]    In one embodiment, the heads-up display  1000  comprises a directional portion  1010  configured to indicate a location of the source  130  of  FIG. 1  relative to a direction the wearer of the eyewear element  910  of  FIG. 9  faces and/or a direction of an antenna (e.g., of the receiver  110  of  FIG. 1 ) that receives the signal  120  of  FIG. 1 . In one embodiment, the directional portion is light-emitting diode display integrated into the eyewear element  910  of  FIG. 9 . The directional portion  1010  can indicate to the wearer (e.g., the diver) where to travel in order to reach the source  130  of  FIG. 1  and/or give an indication of the location of the source  130  of  FIG. 1  so the source  130  of  FIG. 1  can be avoided. In one embodiment, the directional portion  1010  can comprise multiple lights (e.g., five lights) that are green, yellow, or red depending on how the direction of the wearer matches the location of the source  130  of  FIG. 1 . In one embodiment, the multiple lights can have a light sequence that indicates how the direction of the wearer matches the location of the source  130  of  FIG. 1  as well as how to improve a location to become closer to the source  130  of  FIG. 1  (e.g., flashing the right or left lights with regard to which way to turn to more quickly reach the source  130  of  FIG. 1 ). In one embodiment, the directional portion  1010  can communicate text. 
         [0050]    In one embodiment, the heads-up display  1000  comprises a warning portion  1020  configured to indicate an equipment error for equipment employed by the wearer of the eyewear element  910  of  FIG. 9  and/or of another (e.g., another diver of a party of the wearer) as well as other error types (e.g., dangerous depth warning). The warning portion  1020  can be a flashing light to indicate existence of the equipment error. The warning portion  1020  can be more detailed such as a text display on what piece of equipment is in error, specificity on the error, etc. 
         [0051]    In one embodiment, the heads-up display  1000  comprises an identification portion  1030  configured to identify a specific transmitter associated with a specific signal received by a reception component (e.g., the receiver  110  of  FIG. 1 ). In one example, multiple divers can be part of a dive team such as ‘diver A’, ‘diver B’, and ‘diver C.’ Diver C can become injured and press a distress button causing a broadcaster (e.g., the source  130  of  FIG. 1 ) on their body or elsewhere (e.g., the repeater  610  of  FIG. 6 ) to send a distress signal (e.g., the signal  120  of  FIG. 1 ). As part of this distress signal an indication can be provided that diver C is distressed and diver C&#39;s name can be displayed in the identification portion  1030  while the warning portion  1020  flashes. 
         [0052]    In one embodiment, the heads-up display  1000  comprises a distance portion  1040  configured to indicate a distance of the source  130  of  FIG. 1  relative to a location of the wearer of the eyewear element  910  of  FIG. 9 . The distance can be longitudinal distance and/or latitudinal distance. The distance portion  1040  can include a directional arrow to indicate if the wearer is above/below the source  130  of  FIG. 1  or to indicate if the source  130  of  FIG. 1  is moving (e.g., sinking) The distance portion can also disclose distance information for the wearer such as displaying current depth. 
         [0053]    In one embodiment, the heads-up display  1000  comprises a level portion  1050  configured to disclose a level of an oxygen level for a tank set of a wearer of the eyewear element  910  of  FIG. 9 . The oxygen level can include an amount of oxygen remaining in the tank set, an expected duration of proper submersion in view of the amount of oxygen remaining, etc. Different portions can integrate into singular portions, such as the level portion  1050  integrating with the warning portion  1020  such that when the level portion reaches or surpasses a certain threshold, the level portion  1050  can flash and thus also function as the warning portion  1020 . 
         [0054]    The heads-up display  1000  can comprise other portions as well. In one example the heads-up display  1000  can comprise a positional portion configured to positional information for the wearer of the eyewear element  910  of  FIG. 9  (e.g., a depth portion configured to indicate a depth level of the underwater diver, a compass point with degree indication, etc.). This positional portion can replace or be part of the distance portion  1040 . In one example, information integrated with the receiver  110  of  FIG. 1  can have a portion, such as a direction that an antenna of the receiver  110  of  FIG. 1  is facing. While shown as distinct portions, one physical area can be used for multiple portions (e.g., yellow and green for lights of the directional portion  1010  are used for direction while the lights turning red indicate a warning as the warning portion  1020  would indicate). 
         [0055]    Further, the heads-up display  1000  can comprise a physical vital portion configured to disclose physical vital information about a person (e.g., one or more physical vital), such as physical vital information of the diver wearing the mask and/or the physical vitals of a distressed diver. Example physical vitals can comprise heart rate, level of consciousness, breathing rate, body temperature, etc. In one example, the physical vital portion can be configured to be part of the heads-up display  1000  in a limited circumstance, such as when a threshold is met (e.g., the distressed diver becomes unconscious). The physical vital portion can be part of the identification portion  1030  (e.g., when addressing physical vital information about a person associated with the specific transmitter). 
         [0056]      FIG. 11  illustrates one embodiment of an access component  1110 , a configuration component  1120 , and a non-transitory computer-readable medium  1130 . The access component  1110  can access a data set that pertains to an underwater diver (e.g., the wearer). This data set can be the oxygen level, information about the signal  120  of  FIG. 1  (e.g., location of the source  130  of  FIG. 1  as indicated by the signal  120  of  FIG. 1  or the DC signal  270  of  FIG. 2 ), etc. The configuration component  1120  can configure the heads-up display  1000  of  FIG. 10  in accordance with the data set. The heads-up display  1000  of  FIG. 10 , as configured, can be disclosed upon the eyewear element  910  of  FIG. 9  of the underwater diver. This configuration can include determining placement of different portions, determining information for inclusion of different portions, selecting an attribute of different portions (e.g., color of text in the portions based on darkness that surrounds the diver), etc. The non-transitory computer-readable medium  1130  can retain at least one instruction associated with the access component  1110 , the configuration component  1120 , at least one other component disclosed herein, or a combination thereof. 
         [0057]    In one embodiment, the system  1100  can comprise the disclosure component  920  of  FIG. 9 . The disclosure component  920  of  FIG. 9  can cause disclosure of the heads-up display  1000  of  FIG. 10 , as configured, upon the eyewear element  910  of  FIG. 9 . This disclosure can occur while the eyewear element  910  of  FIG. 9  is submerged underwater. In one example, the configuration component  1120  can obtain information from the microcontroller unit  240  of  FIG. 2  while underwater (e.g., the configuration component  1120  accesses information from the microcontroller unit  240  of  FIG. 2 , the configuration component  1120  is part of the microcontroller unit  240  of  FIG. 2 , etc.). The configuration component  1120  can process this information and determine what should be included on the heads-up display  1000  of  FIG. 10 , how content for the heads-up display  1000  of  FIG. 10  should be arranged, etc. In accordance with the determination of the configuration component  1120  the disclosure component  920  of  FIG. 9  can cause disclosure of the heads-up display  1000  of  FIG. 10  (e.g., cause disclosure of the portions  1010 - 1050  of  FIG. 10 ). The system  1100  can function in a feedback manner such that as information is updated (e.g., the diver&#39;s physical position changes relative to the source  130  of  FIG. 1 , new information about diving equipment is learned, etc.) the configuration component  1120  can determine an update for the heads-up display  1000  of  FIG. 10 . In turn, the disclosure component  920  of  FIG. 9  can propagate this update (e.g., when oxygen level goes from 97% to 96% the level portion  1050  of  FIG. 10  can reflect this change). 
         [0058]    In one embodiment, the system  1100  comprises the housing  820  of  FIG. 8 . The housing  820  of  FIG. 8  can be configured to retain the disclosure component  920  of  FIG. 9 , the access component  1110 , the configuration component  1120 , the non-transitory computer-readable medium  1130 , at least one other component or other item disclosed herein, or a combination thereof. The retention can be such that the disclosure component  920  of  FIG. 9 , the access component  1110 , the configuration component  1120 , the non-transitory computer-readable medium  1130 , at least one other component or item disclosed herein, or a combination thereof function without substantial adverse impact when submerged about 350 meter or less (e.g., about 50 meters) underwater (e.g., when submerged at a safe depth for human divers). 
         [0059]      FIG. 12  illustrates one embodiment of a system  1200  comprising a processor  1210  and the non-transitory computer-readable medium  1130 . In one embodiment the non-transitory computer-readable medium  1130  is communicatively coupled to the processor  1210  and stores a command set executable by the processor  1210  to facilitate operation of at least one component disclosed herein (e.g., the first conversion component  310  and/or the second conversion component  320  of  FIG. 3 ). In one embodiment, components disclosed herein (e.g., the access component  1110  and/or the configuration component  1120  of  FIG. 11 ) can be implemented, at least in part, by way of non-software, such as implemented as hardware. In one embodiment the non-transitory computer-readable medium  1130  is configured to store processor-executable instructions that when executed by the processor  1210  cause the processor  1210  to perform a method disclosed herein (e.g., the methods  1300  and  1400  discussed below). 
         [0060]      FIG. 13  illustrates one embodiment of a method  1300  with two actions  1310 - 1320 . At  1310  there is receiving the LF AC signal  280  of  FIG. 2 . This reception can be performed by the diving glove (e.g., that comprises the near-field receiver  360  of  FIG. 3 ) while the diving glove is underwater and is worn by a diver. At  1320  converting the LF AC signal  280  of  FIG. 2  to a DC voltage (e.g., by way of the DC signal  270  of  FIG. 2 ) can occur. The DC voltage can be employed to determine a location of a base signal (e.g., the signal  120  of  FIG. 1 ) from which the LF AC signal  280  of  FIG. 2  is based. In one embodiment, the LF AC signal  280  of  FIG. 2  can be received by way of an inductive pickup in the diving glove, such as from the transmitter  330  of  FIG. 3  held by way of the diving glove when the transmitter  330  of  FIG. 3  transmits the LF AC signal  280  of  FIG. 2  by way of an inductive transmitter. 
         [0061]      FIG. 14  illustrates one embodiment of a method  1400  with four actions  1310 - 1320  and  1410 - 1420 . At  1310  the above-discusses reception can occur and at  1320  the above-discussed conversion can occur. At  1410  determining the location of the base signal through employment of the DC voltage can take place. In one example, the DC voltage can correspond to a direction and/or distance found in a look-up table retained by the diving glove. At  420  there can be causing display of an information set based, at least in part, on the location in a display (e.g., the eyewear element  920  of  FIG. 9  by way of the directional portion  1010  of  FIG. 10 ) of an underwater mask. In one embodiment, the information set includes proximity information with regard to the location and a line of sight for a wearer of the mask (e.g., line of sight with regard to the source  130  of  FIG. 1 ). 
         [0062]    Aspects disclosed herein can be practiced in a variety of environments and/or situations. In one example, an airplane can crash over a large body of water such as the Atlantic Ocean. The source  130  of  FIG. 1  can be an event recorder of the airplane or a piece of equipment worn by the pilot. A mask of the pilot can be configured to function above water as well as underwater and disclose the heads-up display  1000  of  FIG. 10 . The mask can provide an indication of where rescue personnel are located, thus the source  130  of  FIG. 1  can also function as the receiver  110  of  FIG. 1  depending on the perspective. 
         [0063]    In one example, the heads-up display  1000  of  FIG. 10  on the mask can augment radio communication among a dive team and/or help if radio communication fails. In this example, text that is spoken can be displayed on the heads-up display  1000  of  FIG. 10  similar to closed captioning. In addition, portions of the heads-up display  1000  of  FIG. 10  can be used to communicate radio failure information.
