The present invention relates to a waterproof device for diving and a method for operating the same.
Generally, a waterproof device for diving is used to provide safety and convenience functions for diving for a user who dives into water, and as scuba diving becomes popular, such a waterproof device for diving has widely prevailed in daily lives of people.
Examples of the waterproof device for diving include a dive watch, a dive computer, and a dive camera, but because they are very expensive, actually, it is hard to buy them readily.
Recently, a variety of all-in-one waterproof devices for diving each providing such functions for the user, have been developed, and further, because of popularization and performance improvement of a mobile terminal, many studies of all-in-one dive products have been actively made so as to permit the mobile terminal used daily by a user to be usable during his or her diving.
However, the mobile terminal does not have enough components for underwater use. To solve such a problem, a mobile terminal waterproof housing has been developed to allow the mobile terminal to be usable in the case where a user dives into deep water.
With current technologies, however, it is actually difficult that a user who is in deep water checks a water level using the mobile terminal or determines whether the mobile terminal waterproof housing is normally fastened.
Besides, if the mobile terminal waterproof housing is used during the user's diving, it is hard for the user to recognize a touch on the mobile terminal under water, thereby making it difficult to execute and control a program of the mobile terminal.

The control unit 350 determines whether the waterproof housing 100 for diving is normally fastened using the internal pressure of the waterproof housing 100 for diving that is received from the first sensor part 320.
According to an embodiment of the present invention, if a difference between the internal pressure received from the first sensor part 320 after the waterproof housing 100 for diving has been closed and the basic internal pressure before the waterproof housing 100 for diving is closed is over reference internal pressure, the internal pressure of the waterproof housing 100 for diving is instantly drastically increased, so that the control unit 350 determines that the waterproof housing 100 for diving is normally fastened.

Further, the control unit 350 receives the input signal generated from the input part 210 through the second communication part 230.
In a state where the mobile terminal 300 is mounted in the waterproof housing 100 for diving, if the control unit 350 receives the input signal for the Bluetooth connection with the mobile terminal 300 from the input part 210, the control unit 350 provides the Bluetooth connection inducing pop-up for the Bluetooth connection between the waterproof auxiliary unit 200 for diving and the mobile terminal 300 to allow pairing between the waterproof auxiliary unit 200 for diving and the mobile terminal 300.
If the connection setting of the mobile terminal 300 corresponds to the information pop-up, the control unit 350 displays the functional mode on the I/O module 330.
In this case, if a Bluetooth function and a flight mode of the mobile terminal 300 are turned on, the control unit 350 directly provides the diving mode pop-up to perform the conversion into the diving mode, without providing the Bluetooth connection inducing pop-up and the flight mode pop-up for the user.

If it is recognized that the waterproof auxiliary unit 200 for diving and the mobile terminal 300 are connected to each other, the control unit 350 executes the diving application stored in the memory 340 and displays GUI corresponding to the diving application on the I/O module 330.
The control unit 350 displays at least one of the preparation and caution information pop-up before diving and the diving mode on the I/O module 330 and provides notification for the user.
The control unit 350 determines whether the waterproof device 1 for diving is located above water or under water using the external pressure of the waterproof housing 100 for diving that is received from the second sensor part 220.
According to an embodiment of the present invention, the control unit 350 detects whether the external pressure of the waterproof housing 100 for diving that is measured with predetermined intervals is constantly decreased or increased and thus determines whether the waterproof device 1 for diving is located above water or under water.
If it is determined that the external pressure of the waterproof housing 100 for diving, which is detected by the second sensor part 220, is constantly decreased, the control unit 350 determines that the waterproof device 1 for diving is located above water, thereby displaying information of altitude, oxygen concentration, etc. on the I/O module 330 (touchscreen).
If it is determined that the external pressure of the waterproof housing 100 for diving, which is detected by the second sensor part 220, is constantly increased, the control unit 350 determines that the waterproof device 1 for diving is located under water, thereby displaying the pop-up for conversion into the diving mode on the I/O module 330 (touchscreen).
The diving mode includes the quantity of air remaining and the camera mode.
According to another embodiment of the present invention, if the external pressure of the waterproof housing 100 for diving that is measured by the second sensor part 220 is over a second reference value, the control unit 350 determines that the waterproof device 1 for diving is located above water, and contrarily, if the external pressure of the waterproof housing 100 for diving that is measured by the second sensor part 220 is less than the second reference value, the control unit 350 determines that the waterproof device 1 for diving is located under water.
In this case, the second reference value is a predetermined value by a manager, which means average atmospheric pressure on the sea level, for example, 1,018 hPa.
Further, if the control unit 350 receives the input signal for diving start from the input part 210, the control unit 350 allows diving time to be recorded in response to the received input signal.
According to an embodiment of the present invention, the control unit 350 receives the external pressure information from the second sensor part 220 and thus determines the environment of the waterproof device 1 for diving.
If it is determined that the waterproof device 1 for diving is located above water, the control unit 350 determines a sea level altitude, based on a lookup table.
If it is determined that the waterproof device 1 for diving is located under water, the control unit 350 determines a water level, based on a lookup table.
In determining the water level, if a 10 m water level is increased, it is assumed that 1,000 hPa is linearly increased.
Accordingly, the control unit 350 determines the water level corresponding to the difference value between the sensed external pressure and the second reference value is a water level at which the waterproof device 1 for diving is currently located.
According to another embodiment of the present invention, the control unit 350 receives the sea level altitude information or the water level information from the second sensor part 220.
If the external environment of the waterproof housing 100 for diving is determined, the control unit 350 receives the internal pressure of the waterproof housing 100 for diving from the first sensor part 320 and determines the fastened state of the waterproof housing 100 for diving under water.
For example, if it is determined that the waterproof device 1 for diving is currently located above water using the external pressure information received from the second sensor part 220, the control unit 350 determines whether a difference between the internal pressure value and the external pressure value for a predetermined interval is over a third reference value, based on the internal pressure information of the waterproof housing 100 for diving that is detected by the first sensor part 320.
If the difference between the internal pressure value and the external pressure value is over the third reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is normal, and contrarily, if the difference between the internal pressure value and the external pressure value is less than the third reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is abnormal.
In this case, the third reference value is predetermined by a manager and may be 90 hPa as a value that is obtained upon tests and product designs in consideration of changes in a difference between the internal pressure value increased by blocking the housing and keeping the blocked state and the external pressure.
Further, if it is determined that the waterproof device 1 for diving is currently located under water using the external pressure information received from the second sensor part 220, the control unit 350 determines whether the waterproof housing 100 for diving is normally fastened through a difference value between the internal pressure value and the external pressure value for a predetermined interval, based on the internal pressure information of the waterproof housing 100 for diving that is detected by the first sensor part 320.
For example, if a current water level of the waterproof housing 100 for diving is less than a predetermined water level value, the control unit 350 determines whether the difference between the internal pressure value and the external pressure value is over a fourth reference value.
If the difference between the internal pressure value and the external pressure value is over the fourth reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is normal, and contrarily, if the difference between the internal pressure value and the external pressure value is less than the fourth reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is abnormal.
In this case, the fourth reference value is predetermined by the manager and may be 80 hPa as a value that is obtained upon tests and product designs in consideration of changes in a difference between the internal pressure value increased by blocking the housing and keeping the blocked state and the external pressure.
Further, if a current water level of the waterproof housing 100 for diving is over the predetermined water level value, the control unit 350 determines whether the difference between the internal pressure value and the external pressure value is over a fifth reference value.
If the difference between the internal pressure value and the external pressure value is over the fifth reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is normal, and contrarily, if the difference between the internal pressure value and the external pressure value is less than the fifth reference value, the control unit 350 determines that the fastened state of the waterproof housing 100 for diving is abnormal.
In this case, the fifth reference value is predetermined by the manager and may be 40 hPa as a value that is obtained upon tests and product designs in consideration of changes in a difference between the internal pressure value increased by blocking the housing and keeping the blocked state and the external pressure, and the predetermined water level value is 10 m as a value that is obtained upon tests and product designs in consideration of the pressure under water and the internal pressure of the housing.
If it is determined that the fastened state of the waterproof housing 100 for diving is normal, the control unit 350 determines whether water leakage occurs from the waterproof housing 100 for diving at predetermined intervals.
In specific, if it is determined that the fastened state of the waterproof housing 100 for diving is normal and the waterproof device 1 for diving is currently located above water using the external pressure information received from the second sensor part 220, the control unit 350 monitors an inclination (WL) of the internal pressure at predetermined intervals based on the internal pressure information of the first sensor part 320.
The control unit 350 monitors inclinations of the internal pressure with the predetermined number of times of sampling for the predetermined predetermined intervals.
If the inclinations of the internal pressure by the monitored sampling time are all negative (−) numbers, the control unit 350 determines that water leakage occurs from the interior of the waterproof housing 100 for diving.
Further, if it is determined that the fastened state of the waterproof housing 100 for diving is normal and the waterproof device 1 for diving is located under water using the external pressure information received from the second sensor part 220, the control unit 350 monitors an inclination (WL) of the internal pressure at predetermined intervals based on the internal pressure information of the first sensor part 320.
The control unit 350 monitors the inclinations of the internal pressure with the predetermined number of sampling times for the predetermined intervals.
If the inclinations of the internal pressure by the monitored sampling time are all positive (+) numbers, the control unit 350 determines that water leakage occurs from the interior of the waterproof housing 100 for diving.
According to an embodiment of the present invention, the control unit 350 calculates the inclination of the internal pressure, based on changes in the internal pressure of start and end points of the predetermined intervals.
According to the embodiment of the present invention, the inclination (WL) of the internal pressure is calculated by the following mathematical expression 1.
(wherein te represents an end time point of the predetermined intervals, ts a start time point of the predetermined intervals, Pie the internal pressure at the end time point, and Pis the internal pressure at the start time point)
According to another embodiment of the present invention, the control unit 350 calculates the inclination of the internal pressure as the mean of the inclinations calculated based on the predetermined number of sampling times for each point of the predetermined intervals.
According to another embodiment of the present invention, the inclination (WL) of the internal pressure is calculated by the following mathematical expression 2.
(wherein N represents the predetermined number of sampling times, tk a sampling time point, and Pik the internal pressure at the sampling time point)
According to yet another embodiment of the present invention, the control unit 350 calculates the inclinations of the internal pressure at continuous time points for a predetermined intervals and monitors the change of the inclinations.
According to yet another embodiment of the present invention, the inclination (WL) of the internal pressure is calculated by the following mathematical expression 3.
(wherein t represents a calculated time point and dPi(t) the internal pressure at the calculated time point)
Further, according to an embodiment of the present invention, the control unit 350 determines whether the fastened state of the waterproof housing 100 for diving is released using the detected internal pressure of the waterproof housing 100 for diving and the pre-stored basic internal pressure.
In this case, the control unit 350 determines whether the detected internal pressure is in an error range of the pre-stored basic internal pressure.
If it is determined that the detected internal pressure is in an error range of the pre-stored basic internal pressure, the control unit 350 recognizes that the user finishes diving and thus releases the fastened state of the waterproof housing 100 for diving, releases the diving mode, and performs the conversion into a home screen.
In this case, the error range is the range of 10% of the basic internal pressure, but it may be changed by the manager, without being limited thereto.
According to another embodiment of the present invention, the control unit 350 determines whether the waterproof device 1 for diving is currently located above water using the external pressure, releases the diving mode, and performs the conversion into the home screen.
In this case, if it is determined that the waterproof device 1 for diving is located under water before given time and the waterproof device 1 for diving is currently located above water after given time has passed, the control unit 350 recognizes that the user finishes diving and thus releases the diving mode.
According to yet another embodiment of the present invention, the control unit 350 releases the diving mode in consideration of the inclination of the internal pressure change and performs the conversion into the home screen.
In this case, the control unit 350 determines that the water level is decreased or the waterproof device 1 for diving is located above water, and if the inclination of the internal pressure change is changed from a positive number into a negative number, the control unit 350 recognizes that the user finishes diving and thus releases the diving mode.
For example, it is assumed that the basic internal pressure is 1019 hPa, the internal pressure when the waterproof housing 100 for diving is normally fastened is 1113 hPa, the internal pressure in the case of 1 bar (a 10 m water level) is 1200 hPa, the internal pressure in the case of 2 bars (a 20 m water level) is 1246 hPa, and the internal pressure in the case of 3 bars (a 30 m water level) is 1292 hPa.
If the user dives into water, the internal pressure (1113 hPa) when the waterproof housing 100 for diving is normally fastened is increased to the internal pressure (1292 hPa) in the case of 3 bars.
Accordingly, the inclination of the internal pressure change becomes a positive number.
Contrarily, if the user located underwater comes up to the surface of water to finish the diving, the internal pressure is decreased so that the inclination of the internal pressure change becomes a negative number.
The control unit 350 detects the inclination of the internal pressure change and thus releases the diving mode.
In specific, the control unit 350 recognizes that the user finishes the diving in consideration of at least one of the error range of the internal pressure, the external pressure, and the inclination of the internal pressure change, releases the diving mode, and performs the conversion into the home screen.
Further, the control unit 350 determines whether a normal fastened state determination is performed, and based on pre-stored models of mobile terminals covered by insurance, thus checks whether the mobile terminal 300 possessed by the user can be covered by the insurance.
Further, if water leakage occurs, the control unit 350 transmits the water leakage occurrence to a customer center server located at the outside.
For example, the control unit 350 transmits a phrase ‘leakage problem’ to the customer center server.
The control unit 350 receives a solution from the customer center server.
Based on the external pressure information of the second sensor part 220 and the internal pressure information of the first sensor part 320, the control unit 350 allows the current position (under water or above water), water level, and sea level altitude of the waterproof device 1 for diving, the normal or abnormal fastened state of the waterproof housing 100 for diving, and the water leakage state of the waterproof housing 100 for diving after the determination of the normal fastened state to be displayed on the I/O module 330 (touchscreen) through the diving application stored in the memory 340.
The control unit 350 functions as a central processing unit called a microprocessor, and the microprocessor is a computer processor where the arithmetic logical unit, register, program counter, command decoder and control circuit are arranged on at least one silicon chip.
Further, the microprocessor includes a Graphic Processing Unit (GPU) for performing graphic processing of images or videos. The microprocessor may have a system on a chip (SoC) including a core and GPU. The microprocessor may be single-core, dual-core, triple-core, quad-core, and octa-core processors.
Furthermore, the control unit 350 includes a graphic processing board having GPU, RAM or ROM mounted on a separate printed circuit board connected electrically with the microprocessor.
Hereinafter, a method for determining whether the waterproof device 1 for diving according to the present invention is normally fastened will be explained with reference to the attached drawings.
The mobile terminal 300 is coupled to the waterproof housing 100 for diving, and next, the opening and closing member 110 is closed to prevent impurities from entering the waterproof housing 100 for diving (at step S100).
In this case, the basic internal pressure of the waterproof housing 100 for diving is detected by the first sensor part 320 before the opening and closing member 110 is closed, and after the opening and closing member 110 has been closed, the internal pressure of the waterproof housing 100 for diving is in real time detected by the first sensor part 320.
The control unit 350 detects whether a difference value between the basic internal pressure and the measured internal pressure detected by the first sensor part 320 after the opening and closing member 110 has been closed is over a reference internal pressure (at step S110) and thus determines whether the waterproof housing 100 for diving is normally fastened or not.
If the difference value between the basic internal pressure and the measured internal pressure is over the reference internal pressure (YES at the step S110), the control unit 350 determines that the waterproof housing 100 for diving is normally fastened (at step S120).
In this case, the basic internal pressure is 1,018 hPa, and the reference internal pressure is 1,100 hPa. However, they may be varied according to a model of the mobile terminal 300, without being limited thereto.
Contrarily, if the difference value between the basic internal pressure and the measured internal pressure is less than the reference internal pressure (NO at the step S110), the control unit 350 provides a pop-up for refastening of the waterproof housing 100 for diving for the user through the mobile terminal 300.
That is, if the internal pressure of the fastened waterproof housing 100 for diving becomes close to the basic internal pressure, the control unit 350 determines that the waterproof housing 100 for diving is abnormally fastened.

Further, if the mobile terminal 300 and the waterproof device 1 for diving are not pre-paired with Bluetooth and the flight mode of the mobile terminal 300 is not turned on, the control unit 350 displays the Bluetooth connection inducing pop-up and the flight mode pop-up on the I/O module 330.

Contrarily, if it is determined that the difference value between the internal pressure and the external pressure is less than the fifth reference value (NO at the step S523), the control unit 350 determines that the waterproof housing 100 for diving is abnormally fastened (at the step S555).
Next, the control unit 350 displays the abnormal fastened state of the waterproof housing 100 for diving on the diving application of the touchscreen of the mobile terminal 300 (at the step S560).
In this case, the steps S500 to S560 are performed in the same manner as the steps S220 to S280 of
