Description

Technology Field

[0001] The present invention relates to fire alarm processing, and more specifically, to a fire alarm processing method capable of providing reliability regarding the occurrence of a fire alarm and a device supporting the same. Background Technology

[0002] Since early fire suppression is crucial, fire alarm systems are installed and operated in many locations. Conventional fire alarm systems primarily utilize temperature sensors. A fire alarm is triggered when the sensor detects a temperature indicating the occurrence of a fire. However, if the sensor detects an abnormal temperature—for example, if a sudden temperature change occurs when no actual fire has taken place—it may falsely detect a fire situation and trigger a fire alarm. Since a fire alarm triggering when no actual fire has occurred leads to the evacuation of personnel and the dispatch of firefighters to suppress the fire, damage caused by the false alarm can occur.

[0003] Meanwhile, conventional methods have been proposed to reduce false positives in temperature detection and to detect fires more accurately by deploying smoke detection sensors to detect smoke resulting from a fire. However, since smoke detection sensors also react to smoke generated by smoking, the approach using these sensors can also lead to false fire detections.

[0004] Accordingly, there is a need for measures to detect fire occurrences more accurately. Prior art literature

[0005] Korean Registered Patent Publication No. 10-1640152 (July 15, 2016) The problem to be solved

[0006] In order to solve the aforementioned problems, the present invention provides a fire alarm processing method and a device supporting the same that can increase the reliability of fire detection by configuring a sensor module to detect multiple environmental factors that can be recognized as fire occurrence, integrating the acquired sensing values ​​to calculate an integrated sensing value, and comparing and reviewing with an existing integrated sensing value to accurately identify over-detection or false detection regarding fire occurrence detection.

[0007] Meanwhile, the objectives of the present invention are not limited to the above objectives, and other unmentioned objectives will be clearly understood from the description below. means of solving the problem

[0008] The fire alarm processing method of the present invention for achieving the above-described purpose comprises: a server device collecting and storing sensing information regarding environmental factors of a point where a fire alarm device is installed using a plurality of sensors; when a fire alarm occurs at said point, calculating a previous integrated sensing value based on sensing information acquired prior to the occurrence of the fire alarm and calculating a current integrated sensing value based on sensing information acquired after the occurrence of the fire alarm; comparing the previous integrated sensing value and the current integrated sensing value; calculating a reliability regarding the possibility of a fire occurring based on the comparison result; and outputting the reliability.

[0009] Here, the step of calculating the integrated sensing value includes the step of calculating a value by multiplying the sensing values ​​of temperature, PM1, PM2.2, PM10, CO, CO2, and HCHO by weights specified for each of the sensing values ​​and summing them, wherein the specified weights are characterized in that the sensing values ​​that change relatively rapidly in the event of a fire have a larger weight.

[0010] In addition, the step of calculating the reliability may include a step of calculating the reliability corresponding to the comparison result value based on a pre-set reliability table mapped to each comparison result value.

[0011] The above outputting step is characterized by including at least one of the steps of outputting the identifier information of the fire alarm device together with the reliability to a display connected to the server device, and transmitting the reliability and the identifier information of the fire alarm device to a designated administrator terminal.

[0012] In this case, the outputting step is characterized by performing only the step of outputting the reliability and the identification information of the favorable news alarm device to the display if the reliability value of the comparison result is less than a specified value, and performing both the step of outputting the reliability and the identification information of the favorable news alarm device to the display and the step of transmitting to the administrator terminal if the reliability value of the comparison result is greater than or equal to a specified value.

[0013] Additionally, the method may further include a step of omitting the reliability output when the reliability is less than a specified value.

[0014] In addition, the method is characterized by further including the step of performing a suppression request to a manager's terminal related to fire suppression if the reliability is greater than or equal to a specified value, and the step of requesting verification to an investigator's terminal performing verification of the point if the reliability is less than a specified value.

[0015] A server device supporting fire alarm processing according to an embodiment of the present invention comprises a communication interface forming a communication channel with a fire alarm device, a storage unit storing sensing information provided by the fire alarm device, and a server processor functionally connected to the communication interface and the storage unit. The server processor collects and stores sensing information regarding environmental factors at a point where the fire alarm device is installed. When a fire alarm occurs at the point, the server processor calculates a previous integrated sensing value based on sensing information acquired prior to the occurrence of the fire alarm, calculates a current integrated sensing value based on sensing information acquired after the occurrence of the fire alarm, compares the previous integrated sensing value with the current integrated sensing value, calculates a reliability regarding the possibility of a fire occurring according to the comparison result, and outputs the reliability. Effects of the invention

[0016] According to the present invention, in fire detection, the present invention can reduce error recognition regarding fire occurrence by providing information of higher reliability regarding fire occurrence through the comparison of integrated sensing values ​​at different time points.

[0017] In addition, the present invention supports more adaptive processing of fire alarms by adaptively processing weights for various sensing values ​​related to fire detection according to the situation.

[0018] In addition, various effects other than those described above may be disclosed directly or implicitly in the detailed description according to the embodiments of the present invention to be described below. Brief explanation of the drawing

[0029] FIG. 1 is a diagram showing an example of a fire alarm processing system according to an embodiment of the present invention.

[0030] Referring to FIG. 1, a fire alarm processing system (10) according to an embodiment of the present invention may include a fire alarm device (100), a network (50), a server device (200), and an administrator terminal (300). A fire alarm processing system (10) with such a configuration may be configured such that a fire alarm device (100), which is placed in a specific location, such as a certain location in a home, to detect the occurrence of a fire, collects sensing information regarding various environmental factors and provides the collected sensing information to a server device (200), and the server device (200) can perform processing for the occurrence of a fire alarm through analysis of the sensing information. Here, the fire alarm device (100) may be configured to simultaneously process the collection and analysis of sensing information, and in this case, the configuration of the server device (200) in the fire alarm processing system (10) may be omitted.

[0031] The above fire alarm device (100) can be installed and operated in a location for fire detection. This fire alarm device (100) can be installed in a specific location such as a residential house (e.g., a place where cooking facilities are installed) and can collect sensing information using multiple sensors capable of detecting sensing information corresponding to environmental factors. The above fire alarm device (100) can transmit the sensed sensing information to a server device (200). In addition, when a predefined sensing value is detected, the above fire alarm device (100) can recognize that a fire has occurred and output a fire alarm. Along with outputting the fire alarm, the above fire alarm device (100) can transmit the sensing information to the server device (200). As another example, when a fire alarm occurs, the above fire alarm device (100) can collect sensing information, calculate an integrated sensing value from the collected sensing information, and then perform a comparison with the integrated sensing value from a designated previous point in time to calculate the reliability of the currently occurring fire alarm. The above fire alarm device (100) can transmit the calculated reliability to a server device (200) or provide it to an administrator terminal (300).

[0032] The above network (50) can support the formation of a communication channel for signal transmission between each component of the fire alarm processing system (10). For example, the network (50) can be connected to the fire alarm device (100) via a wired connection, and can be connected to the server device (200) and the administrator terminal (300) via at least one of wired and wireless connections.

[0033] The server device (200) can form a communication channel with at least one of the fire alarm device (100) and the administrator terminal (300) through the network (50). The server device (200) can periodically receive and store integrated sensing values ​​from the fire alarm device (100). When the server device (200) receives a fire alarm from the fire alarm device (100) installed at a specific location, it can compare the integrated sensing values ​​at that time with the integrated sensing values ​​at a designated time and, based on this, calculate the reliability of the fire alarm. Here, the reliability may, for example, refer to the correlation between the fire alarm and the occurrence of a fire. If the reliability is high, it can be understood that there is a high probability of an actual fire occurring. The server device (200) can support determining the processing of the fire alarm by outputting the calculated reliability through a display or the like. Alternatively, the server device (200) may provide reliability information regarding the fire alarm to a designated administrator terminal (300) to support the determination of a code of conduct to be executed subsequently regarding the occurrence of the fire alarm. In this regard, the server device (200) may be an organization configured to receive the fire alarm and perform processing thereon, and may be a device deployed in an apartment management office, a fire station, or a fire department.

[0034] The above-mentioned administrator terminal (300) can form a communication channel with the server device (200) through the network (50) and receive a reliability value regarding the occurrence of a fire alarm from the server device (200). When the administrator terminal (300) receives the reliability value, it can output it to a display along with an alarm output. Alternatively, the above-mentioned administrator terminal (300) may receive the reliability value regarding the occurrence of a fire alarm from the fire alarm device (100). The administrator possessing the above-mentioned administrator terminal (300) may be a person related to the place where the fire alarm device (100) is installed, for example, the owner of the place or a fire department manager who has the obligation to handle the situation if a fire occurs at the place.

[0035] As described above, the fire alarm processing system (10) according to an embodiment of the present invention, when a fire alarm occurs, compares the previous integrated sensing value and the current integrated sensing value regarding the occurrence of the fire alarm to calculate and provide a reliability of the fire occurrence, thereby supporting a clearer determination of whether an actual fire has occurred and, depending on the reliability, supporting various post-processing methods.

[0037] FIG. 2 is a drawing showing an example of a fire alarm device configuration according to an embodiment of the present invention.

[0038] Referring to FIG. 2, a fire alarm device (100) according to an embodiment of the present invention may include a communication circuit (110), a sensor module (120), a memory (130), an output device (140), and a control unit (150). Additionally, the fire alarm device (100) may be configured to receive power from a permanent power source installed in the home or may receive power from a separately placed battery.

[0039] The communication circuit (110) may be configured to support the formation of a communication channel for the fire alarm device (100). This communication circuit (110) is connected to a server device (200) via a network (50) and can transmit fire alarm information to the server device (200) when a fire alarm occurs. In this regard, the communication circuit (110) may include a circuit capable of forming a wired communication channel to ensure proper fire alarm transmission even when a fire occurs. Alternatively, the communication circuit (110) may be configured to transmit a fire alarm to an administrator terminal (300) connected to the network (50). In this case, the communication circuit (110) may include a mobile communication module. The communication circuit (110) may also transmit sensing information collected by the sensor module (120) to the server device (200) in response to control by the control unit (150).

[0040] The sensor module (120) may be placed in multiple locations designated for fire detection. The sensor module (120) may include a temperature sensor (121), a dust sensor (123), and a carbon-based sensor (125). The temperature sensor (121) may detect changes in ambient temperature. The temperature sensor (121) may transmit the sensed temperature information to the control unit (150). The dust sensor (123) may sense the dust concentration occurring in the surroundings and transmit the sensed dust information to the control unit (150). The dust information sensed by the dust sensor (123) may include ultrafine dust (PM1), ultrafine dust (PM2.5), and fine dust (PM10). In this regard, the dust sensor (123) may include multiple dust sensors for measuring each type of dust. Alternatively, a single dust sensor may be configured to measure the various types of fine dust described above. The carbon-based sensor (125) can detect carbon-based chemicals in the air. For example, the carbon-based sensor (125) can detect carbon monoxide, carbon dioxide, and formaldehyde. Alternatively, the carbon-based sensor (125) may include sub-sensors capable of detecting carbon monoxide, carbon dioxide, and formaldehyde, respectively.

[0041] The memory (130) can store programs and data related to the operation of the fire alarm device (100). For example, the memory (130) can store sensing information (131) collected by the sensor module (120). The sensing information (131) can be transmitted to a server device (200) in response to control by the control unit (150). If the fire alarm device (100) is configured to detect and output reliability, the memory (130) can store integrated sensing values ​​calculated based on the sensing information (131). The memory (130) can store reliability values ​​calculated through comparison of the integrated sensing values. Additionally, the memory (130) can store pre-set reference sensing values ​​for fire alarm generation and a table for reliability detection. The table may include reliability values ​​corresponding to the comparison results of the integrated sensing values.

[0042] The output device (140) can output information related to the operation of the fire alarm device (100). For example, the output device (140) can output a fire alarm in response to the occurrence of a fire alarm under the control of the control unit (150). The fire alarm may include a designated audio signal.

[0043] The control unit (150) can control the processing, transmission, and program activation of data related to the operation of the fire alarm device (100). This control unit (150) may include at least one processor. The control unit (150) can control the sensor module (120) to collect sensing information corresponding to environmental factors (e.g., temperature, PM1, PM2.5, PM10, CO, CO2, HCHO). The control unit (150) can check whether the collected sensing information is a standard corresponding to a fire alarm output. If the sensing information corresponds to a preset reference sensing value corresponding to a fire alarm, the control unit (150) can output a fire alarm. In this process, the control unit (150) may control the output of a fire alarm according to a specified reference sensing value, or it may control the output to be given when the reliability is greater than or equal to a specified value, even if the fire alarm output conditions are satisfied. In this regard, the control unit (150) can apply a specified weight to the sensing information, calculate an integrated sensing value by integrating the values ​​to which the weights have been applied, and compare the difference with a pre-set integrated sensing value. The control unit (150) can determine the reliability based on the magnitude of the difference between the pre-set integrated sensing value and the current integrated sensing value, and control the output of a fire alarm if the reliability is greater than or equal to a specified value. In this operation, the control unit (150) can compare the integrated sensing value from a certain time prior (e.g., 30 minutes) from the time the fire alarm occurred with the integrated sensing value at the time the fire alarm occurred. Alternatively, the control unit (150) can calculate and accumulate the integrated sensing value at a certain period, and compare the average value of the accumulated integrated sensing values ​​with the current integrated sensing value. Regarding the application of weights, the control unit (150) can determine the application of weights to environmental factors differently based on the sensing information obtained prior to the occurrence of the fire alarm.Basically, the control unit (150) can assign a relatively high weight to environmental factors (e.g., temperature, carbon monoxide, etc.) that are highly related to the occurrence of a fire. If there is an environmental factor detected relatively high among the environmental factors at the point where the fire alarm device (100) is installed, the control unit (150) can set the weight of that environmental factor relatively lower. For example, if the environment is high in fine dust, the control unit (150) can set the weight for fine dust relatively lower. In addition, if the environment is high in formaldehyde (HCHO), the control unit (150) can set the weight for formaldehyde relatively lower.

[0044] Meanwhile, if the server device (200) is configured to perform reliability detection and notification regarding the fire alarm, the control unit (150) can periodically or in real time transmit sensing information (131) to the designated server device (200), and when the fire alarm occurrence condition is satisfied, it can transmit the occurrence of the fire alarm to the server device (200). The control unit (150) can also transmit sensing information at the time of the fire alarm occurrence to the server device (200). The control unit (150) can control the server device (200) to output the fire alarm when the server device (200) instructs the output of the fire alarm.

[0046] FIG. 3 is a diagram showing an example of a server device configuration that supports fire alarm processing according to an embodiment of the present invention.

[0047] Referring to FIG. 3, the server device (200) of the present invention may include a communication interface (210), a storage unit (230), a display (240), and a server processor (250).

[0048] The communication interface (210) can support the formation of a communication channel of the server device (200). For example, the communication interface (210) can form a communication channel with a fire alarm device (100) and receive sensing information and a fire alarm from the fire alarm device (100). The communication interface (210) can transmit information to the fire alarm device (100) instructing a fire alarm output when the reliability of the fire alarm is greater than or equal to a specified value. The communication interface (210) can output the fire alarm occurrence and reliability information to an administrator terminal (300) in response to control by the server processor (250).

[0049] The storage unit (230) can store various data and programs related to the operation of the server device (200). For example, the storage unit (230) can store sensing information (231) received from the fire alarm device (100). At this time, the sensing information (231) stored in the storage unit (230) can be stored separately according to the identifier of each fire alarm device (100). In addition, the storage unit (230) can store integrated sensing values ​​calculated based on the sensing information (231) and reliability history regarding the occurrence of a fire alarm.

[0050] The above display (240) can output various screens related to the operation of the server device (200). For example, the above display (240) can output a list of at least one fire alarm device (100). In addition, the above display (240) can output a fire alarm device among the fire alarm devices (100) that has generated a fire alarm, distinguishing it from other items. In addition, the above display (240) can output the reliability of the generated fire alarm.

[0051] The server processor (250) supports the transmission and processing of data related to the operation of the server device (200) and can perform program control for the operation of the server device (200). For example, when the server processor (250) receives sensing information from the fire alarm device (100), it can store it in the storage unit (230). The server processor (250) can calculate an integrated sensing value based on the sensing information (231) stored in the storage unit (230). At this time, the server processor (250) can calculate and store a previous integrated sensing value corresponding to the sensing information (231) at regular intervals. When the server processor (250) receives a fire alarm and sensing information from the fire alarm device (100), it can compare the current integrated sensing value calculated through the sensing information received at that time with the previous integrated sensing value already stored in the storage unit (230). The server processor (250) can calculate the reliability of fire occurrence based on the difference between the current integrated sensing value and the previous integrated sensing value. To this end, the storage unit (230) may store a table mapping reliability values ​​according to the difference value.

[0052] When the reliability value is detected, the server processor (250) can output the detected reliability value through the display (240). When the server processor (250) outputs the reliability value to the display (240), it can also output the identifier of the fire alarm device (100) where the fire alarm occurred, the location of the fire alarm device (100), the time of the fire alarm occurrence, and reliability information together. Alternatively, the server processor (250) can transmit the reliability value to the administrator terminal (300). At this time, the server processor (250) can provide the identifier of the fire alarm device (100) where the fire alarm occurred, the location of the fire alarm device (100), the time of the fire alarm occurrence, and reliability information together to the administrator terminal (300). The server processor (250) may receive new sensing information from the fire alarm device (100) within a certain time after the fire alarm occurs, compare the integrated sensing value for the newly received sensing information with the previous integrated sensing value calculated before the fire alarm occurred, calculate a new reliability value, and then provide it to the display (240) or the administrator terminal (300). Based on the sensing information (231), the server processor (250) may set weighting settings for environmental factors of the fire alarm device (100) differently depending on the environment in which the fire alarm device (100) is installed. Additionally, the server processor (250) may vary the output means according to the reliability value. For example, if the reliability value is 50-70%, the server processor (250) may output the fire alarm and reliability value to the display (240), and if it is 70% or higher, it may transmit fire alarm-related information and reliability to the administrator terminal (300).

[0054] FIG. 4 is a diagram showing an example of a fire alarm processing method according to an embodiment of the present invention.

[0055] Referring to FIG. 4, in relation to the fire handling method of the present invention, the server processor (250) of the server device (200) may receive a fire alarm from the fire alarm device (100) in step 401. In this regard, the server device (200) may form a communication channel with the fire alarm device (100). When a fire alarm is received from the fire alarm device (100), in step 403, the server processor (250) may determine whether the received fire alarm is the first alarm within a specified time range.

[0056] If it is the first alarm within a specified time range, the server processor (250) may input the current integrated sensing value into S and the previous integrated sensing value into S0 in step 405. To this end, the server processor (250) may periodically receive and store sensing information from the fire alarm device (100) prior to the occurrence of a fire alarm, and may calculate and store an integrated sensing value based on the received sensing information. When a fire alarm occurs, the server processor (250) may calculate an integrated sensing value for the sensing information at that time and input it into S. Meanwhile, if the received fire alarm is not the first alarm, the server processor (250) may skip step 405. The sensing information includes temperature, PM1, PM2.5, PM10, HCHO, CO, and CO2, and these information factors are factors that rise rapidly upon the occurrence of a fire. The calculation of the integrated sensing value may be performed by applying weights (A~F) to the values ​​of each factor and summing them. The above weights (A~F) can be set higher in order of rapid change during a fire.

[0057] In step 407, the server processor (250) can check whether S is greater than S0. If the value of S is greater than S0, the server processor (250) can calculate the change value ((S / S0-TH) / TH) using the reference value (TH) in step 409. The change value is calculated by comparing the rate of increase of S with the reference value (TH), and the formula for detecting the change value is intended to reflect the rapid change in sensing information due to the actual occurrence of a fire.

[0058] In step 411, the server processor (250) can calculate the change value and then derive the reliability based on the change value based on a pre-set table. In step 413, the server processor (250) can output the reliability to the display (240). In step 407, if the S value is less than S0, the server processor (250) can skip steps 409 and 411 and control the output of the reliability for the fire occurrence at step 413 to a specified value (e.g., 0%). Even if the reception of the fire occurrence alarm is stopped, the server processor (250) can re-perform the operation below step 407 after a specified time has elapsed. If the reliability is less than or equal to a specified first value, the server processor (250) outputs the fire occurrence and reliability value only to the display (240), and if the reliability is greater than or equal to a specified second value indicating a high probability of fire occurrence, it can perform output to the display (240) and transmission to the administrator terminal (300). Alternatively, if the server processor (250) is greater than a designated second value with a high probability of fire occurrence, it may output the display form of the fire alarm and reliability output differently from the reliability output of the first value (e.g., screen blinking and siren output).

[0059] Meanwhile, regarding the fire alarm processing method described above, although it has been explained that the server device (200) performs processing for the fire alarm, the present invention is not limited thereto. For example, as described above, when a fire alarm occurs, the fire alarm device (100) may perform processing for it through steps 401 to 413 described above.

[0061] FIG. 5 is a diagram showing another example of a fire alarm processing method according to an embodiment of the present invention.

[0062] Referring to FIG. 5, in relation to the fire handling method of the present invention, the server processor (250) of the server device (200) may receive a fire alarm occurrence in step 501. In this regard, the server device (200) may maintain a communication channel through which the fire alarm device (100) can notify the occurrence of a fire alarm. Additionally, the server device (200) may receive and store sensing information from the fire alarm device (100) at regular intervals. When the server device (200) receives sensing information from the fire alarm device (100), it may calculate an integrated sensing value corresponding to the received sensing information. The integrated sensing value may be, for example, a value obtained by multiplying the values ​​of each sensor of the plurality of sensors included in the sensor module (120) described above by specified weights and then summing them. Regarding the assignment of specified weights, among the sensors, those sensors that are highly related to fire may be assigned relatively larger weights. The above weight assignment may be performed, for example, by the fire alarm device (100) or by the server processor (250). When assigning weights, the server processor (250) checks the sensing information sensed in the environment where the fire alarm device (100) is installed and may assign a relatively smaller weight to the sensing information corresponding to the type of environmental factor that is usually detected relatively more often.

[0063] In step 503, the server processor (250) can obtain the current integrated sensing value. For example, the server processor (250) can calculate the current integrated sensing value from the sensing information provided by the fire alarm device (100) immediately after the fire alarm occurs.

[0064] In step 505, the server processor (250) can compare the accumulated integrated sensing values ​​with the current integrated sensing values. The accumulated integrated sensing values ​​may include the accumulated average value of the integrated sensing values ​​calculated based on the sensing information provided by the fire alarm device (100) during a specified period. Here, the server processor (250) may discard the maximum and minimum values ​​among the integrated sensing values ​​and calculate the average value of the remaining values ​​as the accumulated integrated sensing value. Alternatively, the server processor (250) may calculate the integrated sensing values ​​based on the sensing information received periodically during a specified period of time (e.g., 6 hours) prior to the occurrence of a fire alarm, and calculate the average of the calculated integrated sensing values ​​as the accumulated integrated sensing value.

[0065] In step 507, the server processor (250) can calculate the probability of fire occurrence based on the difference. The server processor (250) can derive a higher probability of fire occurrence the greater the difference between the cumulative integrated sensing value and the current integrated sensing value. Here, the server processor (250) may also detect the rate of change of the current integrated sensing value. In this regard, the server processor (250) may set the sensing information collection cycle shorter than before the fire alarm occurs after the fire alarm occurs, calculate a comparison between the current integrated sensing value calculated through the sensing information obtained after the fire alarm occurs and the cumulative integrated sensing value obtained before the fire alarm occurs, and then calculate the change in the comparison value. The greater the rate of change, the higher the probability may be.

[0066] In step 509, the server processor (250) can determine whether the probability is greater than or equal to a reference value (TH). The reference value (TH) may be a value that can be statistically or empirically suspected as the probability of a fire occurring.

[0067] In step 511, when the above probability exceeds the reference value (TH), the server processor (250) can process a dispatch request for fire suppression. In this regard, the server processor (250) can transmit information such as the location information of the fire alarm device (100) and the time of fire alarm occurrence to a terminal related to fire suppression, such as an administrator terminal (300). Additionally, the server processor (250) may instruct the fire alarm device (100) to output a fire alarm.

[0068] If the above probability is less than or equal to a reference value (TH), in step 513, the server processor (250) may request a confirmation notice. In this regard, the server processor (250) may transmit the relevant information to a terminal owned by an investigator capable of performing a confirmation or patrol regarding the occurrence of a fire. If the above probability is less than a specific value, the server processor (250) may output the reliability of the fire alarm (probability of fire occurrence) on the display (240) of the server device (200) without requesting a separate confirmation notice.

[0069] Meanwhile, regarding other examples of the fire alarm processing method described above, it has been explained that the server device (200) performs processing for the fire alarm, but the present invention is not limited thereto. For example, as described above, when a fire alarm occurs, the fire alarm device (100) and the administrator terminal (300) may perform the above-described steps 501 to 513.

[0070] As explained above, this specification includes details of a number of specific embodiments, but these should not be understood as limiting the scope of any invention or claimables, but rather as descriptions of features that may be characteristic of a specific embodiment of a specific invention.

[0071] Furthermore, although operations are depicted in the drawings in a specific order, this should not be understood as requiring that such operations be performed in that specific or sequential order depicted to obtain a desirable result, or that all depicted operations must be performed. In certain cases, multitasking and parallel processing may be advantageous. Additionally, the separation of the various system components of the embodiments described above should not be understood as requiring such separation in all embodiments, and it should be understood that the described program components and systems can generally be integrated together into a single software product or packaged into multiple software products.

[0072] The description provided herein presents the best mode of the invention and offers examples to explain the invention and to enable a person skilled in the art to manufacture and use the invention. The specification thus written is not intended to limit the invention to the specific terms presented. Accordingly, although the invention has been described in detail with reference to the examples above, a person skilled in the art can make modifications, changes, and variations to these examples without departing from the scope of the invention.
