A distributed acoustic sensing (DAS) system utilizes a fiber optic cable to obtain sensing data associated with vibration signals along the fiber optic cable. For example, by using the fiber optic cable as a sensing element, the DAS system may obtain sensing data (e.g., amplitude data, frequency data, and/or the like) corresponding to each point along a length of the fiber optic cable.
The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
To provide one or more services involving optical communication to a customer (e.g., fiber optic Internet, fiber optic cable, and/or the like), a service provider may route a fiber optic cable across an environment to connect the fiber optic cable to a premises of the customer. To protect the fiber optic cable (e.g., from weather conditions, animals, traffic incidents, and/or the like), the service provider may deploy the fiber optic cable underground. For example, depending on terrain and/or infrastructure within the environment, the service provider may arrange the fiber optic cable in a covered trench, within an underground duct, and/or the like.
However, because the fiber optic cable is hidden underground, a construction crew or other workers may unintentionally damage the fiber optic cable during an activity, such as excavation, construction, demolition, and/or the like. For example, a member of the construction crew, using one or more pieces of equipment to penetrate the ground (e.g., an excavator, a jackhammer, a shovel, and/or the like), may cut the fiber optic cable and thereby disrupt service. As a result, one or more devices of the customer may consume resources (e.g., computing resources, networking resources, and/or the like) attempting to re-establish connectivity, restore a session, contact the service provider, and/or the like. Additionally, the service provider may consume resources (e.g., computing resources, networking resources, vehicle resources, and/or the like) communicating with one or more customers regarding the disrupted service, investigating a source of the disrupted service, repairing the fiber optic cable, and/or the like.
Some implementations herein provide a device (e.g., a fiber optic sensing analysis platform, and/or the like) that analyzes data to identify an activity (e.g., excavation, digging, drilling, and/or the like) and generate an alert or notification in order to minimize a potential that the activity will damage the fiber optic cable. The device may receive, from a sensor device, sensing data associated with the fiber optic cable. The sensing data may be produced by an activity that poses a threat of damage to the fiber optic cable, and the sensing data may identify amplitudes of vibration signals caused by surrounding environment, frequencies of the vibration signals, patterns of the vibration signals, times associated with the vibration signals, and/or locations along the fiber optic cable associated with the vibration signals. The device may process, with a machine learning model, the sensing data to determine a threat level of the activity to the fiber optic cable. The machine learning model may have been trained based on historical information regarding detected signals, historical information regarding sources of the detected signals, and historical information regarding threat levels to the fiber optic cable. The device may perform one or more actions based on the threat level to the fiber optic cable.
By utilizing sensing data to minimize a potential of damage to fiber optic cable, the device may conserve resources that might otherwise have been consumed due to disrupted service. For example, the device may conserve resources that might otherwise have been consumed by the customer attempting to re-establish connectivity, restore a session, contact the service provider, and/or the like. Additionally, the device may conserve resources that might otherwise have been consumed by the service provider communicating with one or more customers regarding the disrupted service, investigating a source of the disrupted service, repairing the fiber optic cable, and/or the like.

However, it should be understood that such values are provided merely as an example. In practice, other values may be utilized, the values may be represented in different forms, the values may include associated units, and/or the like.

Because the fiber optic cable 106 may span large distances (e.g., in a range of approximately 40 miles to approximately 60 miles, and/or the like), the environment may include many different sources of vibration. For example, as shown in
To accurately identify construction activities despite these signal complexities, the fiber sensing system may operate in three phases. In a first phase, which will be described below in connection with
As shown by reference number 114 in
The fiber sensor device 104, based on receiving the first request and as shown by reference number 116, may obtain the baseline sensing data. To obtain the baseline sensing data, the fiber sensor device 104, within the period of time, may inject a series of pulses of light into the fiber optic cable 106 and, using one or more techniques (e.g., coherent Rayleigh optical time domain reflectometry (COTDR), and/or the like), interpret backscatter from the pulses of light to map baseline sensing data to corresponding locations along the fiber optic cable 106. For example, the fiber sensor device 104 may inject a first pulse of light, of the series of pulses of light, into the fiber optic cable 106. As the first pulse of light travels along the fiber optic cable 106, a first vibration signal produced by the first source of vibration 108 may disrupt the first pulse of light at a first location 118, causing the first pulse of light to form backscatter and return to the fiber sensor device 104. The fiber sensor device 104 may detect the backscatter from the first location 118 and analyze the backscatter to determine a first set of vibration data associated with the first vibration signal (e.g., a first amplitude, a first frequency, and/or the like).
The fiber sensor device 104 may repeat this process with a second pulse of light, a third pulse of light, and/or the like, until the fiber sensor device 104 maps the baseline sensing data to an entire length of the fiber optic cable 106. For example, similar to that described above, a second vibration signal produced by the second source of vibration 110 may cause backscatter of a second pulse of light at the second location 120, and a third vibration signal produced by the third source of vibration 112 may cause backscatter of a third pulse of light at a third location 122. The fiber sensor device 104 may detect the backscatter from the second location 120 and the third location 122 and determine, respectively, a second set of baseline sensing data associated with the second vibration signals (e.g., a second amplitude, a second frequency, and/or the like) and a third set of baseline sensing data associated with the third vibration signals (a third amplitude, a third frequency, and/or the like). The fiber sensor device 104 may map the baseline sensing data to the entire length of the fiber optic cable 106 for multiple times of day, different days, and/or the like.
As shown by reference number 124, and based on receiving the first request, the fiber sensor device 104 may provide the baseline sensing data to the fiber optic sensing analysis platform 102. The fiber sensor device 104 may provide the baseline sensing data in batches (e.g., on a triggered basis, on a periodic basis, on a scheduled basis, and/or the like), as a completed set of data, and/or the like. For example, the fiber sensor device 104 may indicate, for multiple times of day, multiple days, and every segment of the fiber optic cable 106 (e.g., every one-meter segment, every five-meter segment, and/or the like), a respective amplitude and frequency. In some implementations, the fiber sensor device 104 may be pre-configured to provide the baseline sensing data to the fiber optic sensing analysis platform 102 (e.g., without receiving the first request). In such a case, the fiber sensor device 104 may update and transmit the baseline sensing data to the fiber optic sensing analysis platform 102 according to a predetermined schedule (e.g., once every 3 months, once every 6 months, and/or the like).
As shown by reference number 126 in
As shown by reference number 130, based on the baseline sensing data, the fiber optic sensing analysis platform 102 may determine a baseline sensing profile to establish baseline vibration characteristics along the fiber optic cable 106. The baseline sensing profile may indicate one or more measures of vibration (e.g., amplitude, frequency, and/or the like) as a function of distance along the fiber optic cable 106. Additionally, or alternatively, the baseline sensing profile may indicate the one or more measures of vibration as a function of time. Thus, in some implementations, the baseline sensing profile may be a multivariate data set. To determine the baseline sensing profile, the fiber optic sensing analysis platform 102 may utilize or more data analysis techniques (e.g., a regression analysis technique, a chi-squared test technique, and/or the like) to determine representative values of the one or more measures of vibrations (e.g., based on the environment being free from construction activities and/or other anomalies) at different locations along the fiber optic cable 106, different times of day, and/or the like. For example, as shown in
As shown by reference number 132 in
The fiber sensor device 104, based on receiving the second request and as shown by reference number 134, may obtain the sensing data associated with the environment. In addition to the environmental sources of vibration (e.g., the playground, the factory, the forest, and/or the like), the environment may include an activity involving ground-penetration (e.g., excavation, digging, drilling, and/or the like), which forms a fourth source of vibration 136. For example, a construction crew (e.g., as part of a new construction project, a reconstruction project, an excavation project, a demolition project, and/or the like) may utilize one or more pieces of equipment to penetrate the ground near the playground. The one or more pieces of equipment may produce a fourth vibration signal. Because sound has additive properties, the fourth vibration signal may superimpose with a fifth vibration signal produced by the playground to create an aggregate vibration signal at the first location 118.
To obtain the sensing data, similar to that described above in connection with
The fiber sensor device 104 may repeat this process with additional light pulses until the fiber sensor device 104 maps the sensing data to an entire length of the fiber optic cable 106. For example, similar to that described above, a sixth vibration signal produced by the second source of vibration 110 may cause backscatter of a second pulse of light at the second location 120, and a seventh vibration signal produced by the third source of vibration 112 may cause backscatter of a third pulse of light at a third location 122. The fiber sensor device 104 may detect the backscatter from the second location 120 and the third location 122 and determine, respectively, a fifth set of sensing data associated with the second vibration signal (e.g., a fifth amplitude, a fifth frequency, and/or the like) and a sixth set of sensing data associated with the third vibration signal (e.g., a sixth amplitude, a sixth frequency, and/or the like). The fiber sensor device 104 may map the sensing data to the entire length of the fiber optic cable 106 substantially continuously, periodically, and/or the like.
As shown by reference number 138, and based on receiving the second request, the fiber sensor device 104 may provide the sensing data to the fiber optic sensing analysis platform 102. The fiber sensor device 104 may provide the sensing data in batches (e.g., on a triggered basis, on a periodic basis, on a scheduled basis, and/or the like). For example, the fiber sensor device 104 may indicate, for multiple times of day and for every segment of the fiber optic cable 106 (e.g., every one-meter segment, every two-meter segment, and/or the like), a new respective amplitude and/or frequency. In some implementations, similar to that described above, the fiber sensor device 104 may be pre-configured to provide the sensing data to the fiber optic sensing analysis platform 102 (e.g., without receiving the second request). In such a case, the fiber sensor device 104 may update and transmit the sensing data to the fiber optic sensing analysis platform 102 according to a predetermined schedule and/or frequency.
As shown by reference number 140 in
As shown by reference number 144, the fiber optic sensing analysis platform 102 may determine that the sensing data satisfies a vibration deviation criteria, relative to the baseline sensing profile, for a duration threshold. The vibration deviation criteria, depending on the type of sensing data that defines the sensing profile (e.g., amplitude data, frequency data, and/or the like), may be a deviation threshold above and/or below the sensing profile. As used herein, satisfying the vibration deviation criteria may, depending on the context, refer to a value being greater than the deviation threshold, greater than or equal to the deviation threshold, less than the deviation threshold, less than or equal to the deviation threshold, equal to the deviation threshold, etc. So as to not trigger a response based on normal vibration variance, the deviation threshold may be in a range of, for example, approximately 8% to approximately 12% above and/or below the measure of vibration indicated by the baseline sensing profile. For example, the deviation threshold may be in the range of approximately 8% to approximately 12% above and/or below the amplitude and/or the frequency indicated by the baseline sensing profile. In some implementations, the fiber optic sensing analysis platform 102 may determine the vibration deviation criteria based on one or more characteristics of the sensing data, such as variance or standard deviation. In such an example, the deviation threshold may be based on not only a representative value of amplitude and/or frequency at a particular location and a particular time of day, but also on underlying sensing data. Furthermore, so as to not trigger a response based on temporary deviations in vibration (e.g., based on a vehicle passing through the environment, and/or the like), the duration threshold may be greater than or equal to approximately 5 minutes. In some implementations, the duration threshold may be greater than or equal to approximately 10 minutes. Other deviation thresholds and/or duration thresholds may alternatively be used.
In some implementations, similar to that described below in connection with
For example, as shown in
As shown by reference number 146 in
To generate the machine learning model 148, the fiber optic sensing analysis platform 102 may train the machine learning model 148 using historical information, such as historical information regarding detected vibrations (e.g., amplitudes of detected vibration signals, frequencies of the detected vibration signals, patterns of the detected vibration signals, times associated with the detected vibration signals, locations associated with the detected vibration signals, and/or the like); historical information regarding sources of the detected vibrations (e.g., types of sources of the detected vibrations, locations of the sources of the detected vibrations, and/or the like); historical information regarding threat levels to the fiber optic cable 106 (e.g., whether the sources of the detected vibrations are associated with activities that are capable of damaging the fiber optic cable 106, a measure of how quickly the activities are capable of damaging the fiber optic cable 106, and/or the like); and/or the like.
In some implementations, the fiber optic sensing analysis platform 102 may perform a data preprocessing operation when generating the machine learning model 148. For example, the fiber optic sensing analysis platform 102 may preprocess the historical information to remove non-ASCII characters, white spaces, confidential data, and/or the like. In this way, the fiber optic sensing analysis platform 102 may organize thousands, millions, or billions of data items for machine learning and model generation.
In some implementations, the fiber optic sensing analysis platform 102 may perform a training operation when generating the machine learning model 148. For example, the fiber optic sensing analysis platform 102 may portion the historical information into a training set (e.g., a set of data to train the machine learning model 148), a validation set (e.g., a set of data used to evaluate a fit of the machine learning model 148 and/or to fine tune the machine learning model 148), a test set (e.g., a set of data used to evaluate a final fit of the machine learning model 148), and/or the like. In some implementations, the fiber optic sensing analysis platform 102 may preprocess and/or perform dimensionality reduction to reduce the historical information to a minimum feature set. In some implementations, the fiber optic sensing analysis platform 102 may train the machine learning model 148 on this minimum feature set, thereby reducing processing to train the machine learning model 148, and may apply a classification technique, to the minimum feature set.
In some implementations, the fiber optic sensing analysis platform 102 may use a classification technique, such as a logistic regression classification technique, a random forest classification technique, a gradient boosting machine learning (GBM) technique, and/or the like, to determine the threat level to the fiber optic cable 106. Additionally, or alternatively, the fiber optic sensing analysis platform 102 may use a naïve Bayesian classifier technique. In this case, the fiber optic sensing analysis platform 102 may perform binary recursive partitioning to split the historical information of the minimum feature set into partitions and/or branches and use the partitions and/or branches to perform predictions (e.g., that particular vibration signal characteristics indicate an activity involving ground-penetration, that particular vibration signal characteristics indicate that the fiber optic cable 106 is at risk of being cut within a certain amount of time, and/or the like). Based on using recursive partitioning, the fiber optic sensing analysis platform 102 may reduce utilization of computing resources relative to manual, linear sorting and analysis of data items, thereby enabling use of thousands, millions, or billions of data items to train a model, which may result in a more accurate model than using fewer data items.
Additionally, or alternatively, the fiber optic sensing analysis platform 102 may train the machine learning model 148 using a supervised training procedure that includes receiving input to the machine learning model 148 from a subject matter expert, which may reduce an amount of time, and/or an amount of processing resources to train the machine learning model 148 relative to an unsupervised training procedure. In some implementations, the fiber optic sensing analysis platform 102 may use one or more other model training techniques, such as a neural network technique, a latent semantic indexing technique, and/or the like. For example, the fiber optic sensing analysis platform 102 may perform an artificial neural network processing technique (e.g., using a two-layer feedforward neural network architecture, a three-layer feedforward neural network architecture, and/or the like) to perform pattern recognition with regard to patterns of whether certain vibration signal characteristics were associated or not associated with damage to the fiber optic cable 106. In this case, using the artificial neural network processing technique may improve an accuracy of the model generated by the fiber optic sensing analysis platform 102 by being more robust to noisy, imprecise, or incomplete data, and by enabling the fiber optic sensing analysis platform 102 to detect patterns and/or trends undetectable to human analysts or systems using less complex techniques.
In some implementations, a different device, such as a server device, may generate and train the machine learning model 148. The different device may send the machine learning model 148 for use by the fiber optic sensing analysis platform 102. The different device may update and send (e.g., on a scheduled basis, on an on-demand basis, on a triggered basis, on a periodic basis, and/or the like) the machine learning model 148 to the fiber optic sensing analysis platform 102.
After generating the machine learning model 148, the fiber optic sensing analysis platform 102 may use the machine learning model 148 to determine, based on the sensing data, the threat level to the fiber optic cable 106. In other words, the fiber optic sensing analysis platform 102 may input, into the machine learning model 148, the sensing data (e.g., amplitudes of vibration signals, frequencies of the vibration signals, patterns of the vibration signals, times and/or durations associated with the vibration signals, locations along the fiber optic cable 106 associated with the vibration signals, and/or the like), and the machine learning model 148 may output the threat level. The threat level may be represented by a score, which indicates whether the source of the sensing data is associated with an activity capable of damaging the fiber optic cable 106, a measure of how quickly the activity is capable of damaging the fiber optic cable 106, and/or the like. In this example, the machine learning model 148 may output a relatively high score for the threat level, due to the fourth source of vibration 136 being associated with an activity involving ground penetration.
As shown by reference number 150 in
To identify a geographic location of the first location 118 (and other locations along the fiber optic cable 106), the fiber optic sensing analysis platform 102 may operate in conjunction with one or more additional devices to obtain correlated location data associated with the fiber optic cable 106. For example, the one or more additional devices may include a vibration device, a measurement platform, and/or the like. In such an example, the vibration device may generate a series of vibrations having predetermined frequencies and predetermined amplitudes along a predetermined geographic route that approximates a path of the fiber optic cable 106. Similar to that described above, the fiber sensor device 104 may interpret backscatter of light from the fiber optic cable 106 to determine a distance between the first location 118 of the fiber optic cable 106 and a geographic location of a vibration. Based on the distance and the geographic location of the vibration, the measurement platform may determine the geographic location of the first location 118 along the fiber optic cable 106. The measurement platform may transmit the geographic location to the fiber optic sensing analysis platform 102.
In some implementations, the fiber optic sensing analysis platform 102 may approximate the geographic location of the first location 118 (and other locations along the fiber optic cable 106) using the sensing data and geographic data associated with the environmental sources of vibrations. For example, the fiber optic sensing analysis platform 102 may obtain geographic data (e.g., an address, geographic coordinates, and/or the like) of the playground, the factory, and the forest. Based on the sensing data, the fiber optic sensing analysis platform 102 may assess, to a reasonable degree of certainty, that the first source of vibration 108 is the playground, the second source of vibration 110 is the factory, and the third source of vibration 112 is the forest. As a result, the fiber optic sensing analysis platform 102 may determine an approximate geographic location of the first location 118, the second location 120, and the third location 122.
Additionally, or alternatively, the one or more actions may include causing the fiber optic cable 106 to be tested to verify that the fiber optic cable 106 is properly functioning. For example, the fiber optic sensing analysis platform 102 may transmit an instruction to the fiber sensor device 104. The instruction may indicate that the fiber sensor device 104 is to run a test (e.g., by injecting one or more light pulses into the fiber optic cable 106) to verify that the fiber optic cable 106 is properly functioning and the sensing data is accurate, transmit a report based on a result of the test, and/or the like. The instruction may indicate that the fiber sensor device 104 is to run the test on an on-demand basis, on a periodic basis, on a scheduled basis, and/or the like. Based on receiving the instruction, the fiber sensor device 104 may run the test and communicate with the fiber optic sensing analysis platform 102 that the fiber optic cable 106 is properly functioning.
Additionally, or alternatively, the one or more actions may include causing an autonomous vehicle to be dispatched to the first location 118 to provide an alert regarding a potential for damage of the fiber optic cable 106. For example, the fiber optic sensing analysis platform 102 may transmit an instruction to the autonomous vehicle (e.g., an unmanned aerial vehicle). The instruction may indicate that the autonomous vehicle is to travel to the first location 118, provide the alert (e.g., auditorily, visually, and/or the like) regarding a presence of the fiber optic cable 106, transmit a report regarding the alert to the fiber optic sensing analysis platform 102, and/or the like. Based on receiving the instruction, the autonomous vehicle may provide the alert to the construction crew to cause the construction crew to cease the activity, transmit the report to the fiber optic sensing analysis platform 102, and/or the like.
Additionally, or alternatively, the one or more actions may include causing a technician to be dispatched to the first location 118 to provide an alert regarding a potential for damage of the fiber optic cable 106. For example, the fiber optic sensing analysis platform 102 may transmit an instruction to a device of the technician nearest to the first location 118. The instruction may indicate the technician is to travel to the first location 118 (e.g., via a vehicle), provide the alert to the construction crew involved in the activity, provide a report regarding the alert to the fiber optic sensing analysis platform 102, and/or the like. Based on receiving the instruction, the technician may provide the alert to the construction crew to cause the construction crew to cease activity, provide the report to the fiber optic sensing analysis platform 102, and/or the like.
Additionally, or alternatively, the one or more actions may include sending a notification to one or more devices regarding a potential for damage to the fiber optic cable 106. For example, the fiber optic sensing analysis platform 102 may transmit the notification to a device of the technician nearest to the first location 118, to a device of a member of the construction crew, and/or the like. Based on receiving the notification, the technician and/or the member of the construction crew may cause the construction crew to cease the activity.
Additionally, or alternatively, the one or more actions may include updating the machine learning model 148. For example, based on obtaining a verification that the fourth source of vibration 136 is associated with an activity posing a threat of damage to the fiber optic cable 106, the fiber optic sensing analysis platform 102 may update the machine learning model 148 to include the sensing data mapped to the fourth source of vibration 136. In other cases, the fiber optic sensing analysis platform 102 may update the machine learning model 148 based on receiving a notification that a source of vibration is not associated with an activity posing a threat of damage to the fiber optic cable 106. Thus, over time, the machine learning model 148 may become increasingly fine-tuned to recognize activities that pose a threat of harm to the fiber optic cable 106.
By analyzing sensing data to identify, in real-time or near real-time, activities that may pose a threat of damage to the fiber optic cable 106, the fiber optic sensing analysis platform 102 may minimize a potential of damage to the fiber optic cable 106. As a result, the fiber optic sensing analysis platform 102 may conserve resources that might otherwise have been consumed due to damage to the fiber optic cable 106 and/or disrupted service. For example, the fiber optic sensing analysis platform 102 may conserve resources that might otherwise have been consumed by the customer attempting to re-establish connectivity, restore a session, contact the service provider, and/or the like. Additionally, the fiber optic sensing analysis platform 102 may conserve resources that might otherwise have been consumed by the service provider communicating with one or more customers regarding the disrupted service, investigating a source of the disrupted service, repairing the fiber optic cable 106, and/or the like. Furthermore, by utilizing artificial intelligence techniques, the fiber optic sensing analysis platform 102 may conserve resources that might otherwise have been consumed as a result of false positives and/or false negatives in association with the baseline sensing profile.

In some implementations, process 400, prior to receiving the sensing data, may further include receiving baseline sensing data associated with the fiber optic cable. The baseline sensing data may be produced within an environment encompassing the fiber optic cable. In some implementations, the baseline sensing data may be produced by the environment over a period of time. The baseline sensing data may indicate an amplitude of a vibration signal. The baseline sensing data may indicate a frequency of a vibration signal.
In some implementations, process 400, prior to receiving the sensing data, may further include determining, based on the baseline sensing data, a baseline sensing profile that indicates a measure of vibration as a function of distance along the fiber optic cable and as a function of time. The measure of vibration may be at least one of amplitude or frequency. Determining the baseline sensing profile comprises analyzing the baseline sensing data to identify a representative value of the amplitude for a plurality of times of day and for a plurality of locations along a length of the fiber optic cable.
In some implementations, process 400, prior to processing the sensing data, may further include determining, based on the sensing data, that the sensing data satisfies a vibration deviation criteria relative to the baseline sensing profile. In some implementations, the sensing data may satisfy the vibration deviation criteria for a duration threshold. The sensing data, by satisfying the vibration deviation criteria for the duration threshold, may indicate that the environment includes a type of activity associated with an increased likelihood of damage to the fiber optic cable relative to the baseline sensing data. In some implementations, processing the sensing data may be based on the sensing data satisfying the vibration deviation criteria. In some implementations, processing the sensing data may be based on the sensing data satisfying the vibration deviation criteria for the duration threshold. The vibration deviation criteria may include a deviation threshold in a range of approximately 8% to approximately 12% above and/or below the measure of vibration indicated by the baseline sensing profile. The duration threshold may be greater than or equal to approximately 5 minutes. In some implementations, the deviation threshold may be greater than the amplitude of the baseline sensing data by approximately 10% of the amplitude of the baseline sensing data. In some implementations, the deviation threshold may deviate from the frequency of the baseline sensing data by approximately 10% of the frequency of the baseline sensing data.
In some implementations, process 400, prior to processing the sensing data, may further include training the machine learning model based on historical information regarding detected vibrations, historical information regarding sources of the detected vibrations, and historical information regarding threat levels to the fiber optic cable. The historical information regarding the detected vibrations may indicate amplitudes of detected vibration signals, frequencies of the detected vibration signals, patterns of the detected vibration signals, times associated with the detected vibration signals, and locations associated with the detected vibration signals. The historical information regarding the sources of the detected vibrations may indicate types of sources of the detected vibrations and locations of the sources of the detected vibrations. The historical information regarding the threat levels to the fiber optic cable may indicate whether the sources of vibration are associated with activities that are capable of damaging the fiber optic cable and a measure of how quickly the activities are capable of damaging the fiber optic cable.

As used herein, satisfying a threshold may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, etc., depending on the context.
To the extent the aforementioned implementations collect, store, or employ personal information of individuals, it should be understood that such information shall be used in accordance with all applicable laws concerning protection of personal information. Additionally, the collection, storage, and use of such information can be subject to consent of the individual to such activity, for example, through well known “opt-in” or “opt-out” processes as can be appropriate for the situation and type of information. Storage and use of personal information can be in an appropriately secure manner reflective of the type of information, for example, through various encryption and anonymization techniques for particularly sensitive information.
Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various implementations. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of various implementations includes each dependent claim in combination with every other claim in the claim set.
