Turning now to the drawings, configurable dive masks in accordance with embodiments of the invention are illustrated. Divers often wear dive masks in order to protect their face and enhance vision while underwater. Dive masks are commonly made of a relatively clear lens (such as a tempered glass plate or a composite lens) and a skirt of rubber or silicone that forms a watertight seal with the diver's face. In addition to the dive masks, divers often have a variety of additional equipment such as, but not limited to, one or more air tanks, rebreathers, dive computers, and sensors. Divers often need to keep track of data about the dive and/or their equipment while submerged. This can be data regarding pressure, depth, dive time remaining, time to decompression, oxygen time remaining, nitrogen tissue load, or any other piece of data that is relevant to the diver. Information may need to be interpreted in different ways depending on the type of dive, such as, but not limited to, free diving, shallow diving, or deep diving. Such information can be used to help ensure the safety of the diver. Dive devices, such as, but not limited to, the equipment carried by divers as described above, can generate dive device data including (but not limited to) data that describes this information. The dive device data can then be shown on a display that is integrated into or attached to the configurable dive mask. In many embodiments, the dive device data is transmitted to a dive mask worn by a second diver to alert the second diver. In this way, a second diver can be alerted to the dive conditions being experienced by the first diver. For example, a dive instructor can be notified when a dangerous condition is occurring with a student's equipment.
In many embodiments, configuration data can be used to map dive device data to a display device. Configuration data can be obtained from the configuration device via a network. The configurable dive mask can also obtain configuration data directly from configuration devices. Communication between the configurable dive mask and the configuration devices can be facilitated by a configuration interface. In a variety of embodiments, the configuration interface can operate using radio frequency (RF) communication technology, or any other type of communication technique that is operable above water. On the surface, RF technology can be used to communicate quickly over long distances; however, RF signals typically do not propagate effectively underwater. While submerged, dive device data can be obtained from one or more dive devices via a dive device data interface. The dive device data interface can operate using magnetic field communication technology, which has a range far enough to span more than the length of the diver's body, or any other communication technology that functions while submerged. In this way, the configurable dive mask can be adapted to display data in a variety of ways depending on the needs of the diver for a particular dive. This can aid the diver in being able to quickly view and process relevant information to dive in a safe and efficient manner. Additionally, the configuration data and/or obtained dive device data can be transmitted utilizing the configuration interface and/or dive device data interface as appropriate to the requirements of specific applications of embodiments of the invention.

In many embodiments, the configuration interface 220 and/or the dive device data interface 230 utilize a plurality of transmitters to communicate using a variety of communication technologies.
In some situations, multiple divers will be diving in close proximity to each other. It can be beneficial to the diver to only see dive device data from specific devices; for example, dive device data from their own dive devices and/or one or dive devices of a diving partner. In numerous embodiments, the dive device data interface 230 can recognize dive devices and receive and/or display dive device data only from those dive devices.

In this way, the configurable dive mask can display only the dive device data specified.
Although a specific architecture for a configurable dive mask in accordance with an embodiment of the invention is conceptually illustrated in
Configurable dive masks can be designed to display dive device data in a variety of ways. In many embodiments, the configurable dive masks include configuration data that defines how the dive device data is displayed using a display integrated into or attached to the configurable dive mask. The configuration data can be obtained from any of a variety of configuration devices while the configurable dive mask is above water. In this way, the configurable dive mask can be reconfigured to display a variety of data during a dive that is relevant to the diver.
Dive device data can be processed in accordance with configuration data in order to display the dive device data in the way the user wants. Configuration data can be obtained from a variety of configuration devices via a configuration interface. Configuration devices can define the configuration data according to a variety of parameters including, but not limited to, breathing gas mix composition, diver gender, diver weight, what dive device data to display, how to display the dive device data, and/or any other configuration parameter as appropriate to specific applications of embodiments of the invention. Configuration data can be used to map particular values, ranges of values, and/or properties of dive device data to the display device. In this way, the display of the dive device data is tailored to the capabilities of the display device and the dive device data itself.
A diver may wish to configure the configurable dive mask to display a particular type of dive device data during a dive. The diver can configure the configurable dive mask to display that dive device data and then, while diving, the dive mask obtains dive device data and displays the dive device data according to the configuration. Furthermore, a diver can alter the display of information to change over the course of a dive in accordance with embodiments of the invention. The dive can configure the configurable dive mask to alter the display of data based on dive device data such as, but not limited to, time, depth, submersion, or any other piece or combination of dive device data as appropriate to the requirements of embodiments of the invention. In this way, the diver is presented with the dive device data in a custom way to fit the diver's choosing.
For example, a diver may wish to keep track of time during a dive. The configuration data can be made such that the processor selects the time from a host of obtained dive device data and displays the time on the configurable dive mask display. Similarly, configuration data can be made to select and display the breathing gas pressure, water pressure, or any other piece of dive device data that is appropriate to the requirements of specific applications. In many embodiments, the configuration data can contain more complex instructions, such as displaying multiple pieces of dive device data and any other information generated as a function of one or more pieces of dive device data. For example, depth as a function of water pressure, nitrogen tissue load as a function of multiple pieces of dive device data such as, but not limited to, time, depth, breathing rate, or any other piece of dive device data needed to compute complex functions. In a variety of embodiments, the configuration data includes a serial number, diver identification data, depth data, distance data, heading data, pressure data, and/or text data related to the dive. Additionally, the configuration data and/or obtained dive device data can be transmitted utilizing a variety of processes, including those described below.
In order to display current information, the configurable dive mask can obtain updates from dive devices. During the dive, the configurable dive mask can obtain dive device data though the dive device interface continuously or on a schedule. The configurable dive mask can process the dive device using configuration data and a processor. Based on the configuration data, the processor can chose what dive device data to display, and how to display dive device data. In a variety of embodiments, preprocessing of dive device data can occur, in part or in whole, on a processor external to the configurable dive mask. Dive devices such as, but not limited to, dive computer and rebreather computers can process dive device data in a similar fashion as the configurable dive mask. Preprocessing of one or more pieces of dive device data can be performed using an external processor. If dive device data is preprocessed on a processor separate from the configurable dive mask, the configurable dive mask can obtain the preprocessed dive device data from the underwater processor via the dive device data interface. The preprocessed dive device data can then be processed on the configurable dive mask utilizing techniques similar to those described above.

Processes for analyzing dive device data are discussed further below.
During a dive, dive device data can be obtained from a variety of dive devices via the dive device data interface. Dive device data can be processed in order to generate display data. Displaying dive device data can include a variety of different transformations. In some embodiments, processing steps can be determined by the configuration data. In other embodiments, some, but not all processing steps can be determined by the configuration data. The configuration data can include instructions for combining multiple pieces of device data into the display data to be displayed using the display device. Processing of dive device data from one or more pieces of dive device data can occur on external processors.
Configurable dive masks can map display data to the display device. Display data can be processed from dive device data in accordance with configuration data using a display processing application. The display processing application can determine the mapping of dive device data to the display device based on the configuration data provided for display using the configurable dive mask. Configuration data can describe the output capabilities of the display device and how dive device data values, ranges of values, or any other property of dive device data, can be mapped to the display device. For example, a configurable dive mask may have a display device consisting of a red, a yellow, and a green light emitting diode (LED). Configuration data can be generated such that if there is over an hour of air time remaining, then the green LED can be turned on. If there is less than an hour of air time, but more than 15 minutes of air time, the yellow LED can be turned on. If there is less than 15 minutes of air time, the red LED can be turned on. If the display device is a segmented display, the display can show the time in minutes remaining and/or a textual interpretation of the dive device data such as, but not limited to, “OK,” “WARNING,” or “DANGER.” While the above is one example of a configurable dive mask configuration, any of a variety of configuration data and display devices can be used in accordance with embodiments of the invention.
Divers may want to keep logs of dives they have taken. In some embodiments, any combination of display data, dive device data, and configuration data can be logged in configurable dive mask memory, or in an external memory device. In many embodiments, configuration data can be matched with dive display data and/or dive device data in the log file. In this way, the diver can keep store information regarding previous dives and, in some embodiments, the configuration data used for specific dives.

Additionally, display data generated based on the dive device data can also be stored. In several embodiments, configurable dive masks can transmit this stored data using the configuration interface to one or more devices when the configurable dive mask is above water. In this way, the dive device data, display data, and/or configuration data can be transmitted for viewing, testing, processing, and/or storage using external devices. For example, the display data can be analyzed to determine potential bugs in the configuration data and facilitate improvements in the display of obtained dive device data. Additionally, the stored data can be utilized to reconstruct particular portions of the dive.
