Embodiments of the current invention relate to computing devices for use with irrigation systems to process geospatial data.
Irrigation systems distribute water or other fluids over an area of land to be irrigated. Center-pivot irrigation systems are ideal for use in fields having circular crop areas, while lateral-move irrigation systems are ideal for use in square, rectangular, and irregular-shaped fields. Each type of irrigation system includes a plurality of motor-driven mobile towers that support a water-carrying conduit to which a plurality of sprinklers are coupled. Each type of irrigation system may also include a plurality of sensors which monitor the performance of the irrigation system components. For example, sensors may measure pressure of the water in the conduit, water flow through the sprinklers, and other fluid related metrics. Sensors may also measure the electrical performance of the drive motors for the mobile towers. In addition, sensors may determine a geolocation, such as a latitude and longitude, of the various components of the irrigation system. Typically, data from each sensor is output as a stream of digital data samples. An irrigation system controller receives the sensor data and the geolocation data. The irrigation system controller also links the sensor data with the geolocation data such that each digital data sample for each sensor is linked with the geolocation sample for the sensor at the time when the sensor sample was taken. The linked sensor data and geolocation data is geospatial data. Traditionally, the irrigation system controller transmitted all of the geospatial data to an external computer server for processing and analysis of the geospatial data. In addition, automation processes that are critical for the operation of the irrigation system may be managed by the external computer server as well. Unfortunately, this offsite data processing complicates data flow within the irrigation system, increases transmission data payloads, delays the actions taken from processing and analysis of the geospatial data, and increases the cost of operation of the irrigation system. And, if communication between the irrigation system and the external computer server is lost, then critical automation processes may not occur.
Embodiments of the current invention solve the above-mentioned problems and provide a distinct advance in the art of irrigation system data management. Specifically, embodiments of the current invention may provide a computing device and method for processing geospatial data associated with an irrigation system. These embodiments provide onsite irrigation system geospatial data analysis and processing that simplifies data flow within the irrigation system, decreases transmission data payloads, allows for rapid action to be taken from processing and analysis of the geospatial data, and decreases the cost of operation of the irrigation system. Furthermore, utilizing an onsite computing device means that critical automation processes can continue even if communication to an external computer server is lost.
The computing device broadly comprises a processing element in electronic communication with a memory element. The processing element is configured or programmed to receive sensor data over time from a plurality of sensors associated with the irrigation system, receive or determine geolocation data, link data from each sensor with geolocation data to form geospatial data, determine trends in the geospatial data for each sensor or a group of sensors, determine changes or adjustments in an operation of components of the irrigation system based on trends determined in the geospatial data, and output an electronic signal whose analog level or digital data value varies according to the changes or adjustments in the operation of components of the irrigation system.
The method broadly comprises the steps of receiving sensor data from a plurality of sensors; receiving or determining geolocation data; linking data from each sensor with geolocation data to form geospatial data; determining trends in the geospatial data for each sensor or a group of sensors; determining changes or adjustments in an operation of components of the irrigation system based on trends determined in the geospatial data; and outputting an electronic signal whose analog level or digital data value varies according to the changes or adjustments in the operation of components of the irrigation system.

The valves are positioned along the length of the conduit and are configured to control the flow of fluid through the conduit. The pump is configured to provide pressure of the fluid through the conduit. The sensors are configured to sense performance quantities and/or operating parameters of the drive motor of each mobile tower, the valves, and the pump. The computing device includes a processing element in electronic communication with a memory element. The processing element is configured or programmed to receive data over time from the sensors, receive or determine geolocation data, link data from each sensor with geolocation data to form geospatial data, determine trends in the geospatial data for each sensor or a group of sensors, determine changes or adjustments in an operation of the drive motor of each mobile tower, the valves, and the pump based on trends determined in the geospatial data, and output an electronic signal whose analog level or digital data value varies according to the changes or adjustments in the operation of the drive motor of each mobile tower, the valves, and the pump.

The sensors 16 generally sense or detect performance quantities and/or operating parameters of various components of the irrigation system 12 over time. That is, each sensor 16 outputs an analog electric voltage or electric current level, which may be sampled, or a digital data sample for a series of time periods.

In certain embodiments, the communication element 40 may also couple with optical fiber cables. In some embodiments, the communication element 40 may be further configured to communicate with satellites. The communication element 40 may be in electronic communication with the memory element 42 and the processing element 44.
The memory element 42 may be embodied by devices or components that store data in general, and digital or binary data in particular, and may include exemplary electronic hardware data storage devices or components such as read-only memory (ROM), programmable ROM, erasable programmable ROM, random-access memory (RAM) such as static RAM (SRAM) or dynamic RAM (DRAM), cache memory, hard disks, floppy disks, optical disks, flash memory, thumb drives, universal serial bus (USB) drives, solid state memory, or the like, or combinations thereof. In some embodiments, the memory element 42 may be embedded in, or packaged in the same package as, the processing element 44. The memory element 42 may include, or may constitute, a non-transitory “computer-readable medium”. The memory element 42 may store the instructions, code, code statements, code segments, software, firmware, programs, applications, apps, services, daemons, or the like that are executed by the processing element 44. The memory element 42 may also store data that is received by the processing element 44 or the device in which the processing element 44 is implemented. The processing element 44 may further store data or intermediate results generated during processing, calculations, and/or computations as well as data or final results after processing, calculations, and/or computations. In addition, the memory element 42 may store settings, data, documents, sound files, photographs, movies, images, databases, and the like.
The processing element 44 may comprise one or more processors. The processing element 44 may include electronic hardware components such as microprocessors (single-core or multi-core), microcontrollers, digital signal processors (DSPs), field-programmable gate arrays (FPGAs), analog and/or digital application-specific integrated circuits (ASICs), or the like, or combinations thereof. The processing element 44 may generally execute, process, or run instructions, code, code segments, code statements, software, firmware, programs, applications, apps, processes, services, daemons, or the like. The processing element 44 may also include hardware components such as registers, finite-state machines, sequential and combinational logic, configurable logic blocks, and other electronic circuits that can perform the functions necessary for the operation of the current invention. In certain embodiments, the processing element 44 may include multiple computational components and functional blocks that are packaged separately but function as a single unit. The processing element 44 may be in electronic communication with the other electronic components through serial or parallel links that include universal busses, address busses, data busses, control lines, and the like.
The processing element 44 may be operable, configured, or programmed to perform the following functions by utilizing hardware, software, firmware, or combinations thereof. The processing element 44 receives input data, through the communication element 40, from the sensors 16 and any other data source including users, computer models, external stations, or other external sources. Each sensor 16 may output a series of digital data samples or an analog electric voltage or electric current. Analog levels may be converted by an analog to digital converter and sampled. Each sample is a data point. The processing element 44 also receives or determines geolocation data. As discussed above, a location determining sensor may communicate geolocation data to the processing element 44. In some embodiments, the irrigation system 12 may include, or be in communication with, a plurality of location determining sensors. For example, each mobile tower 30 may include a location determining sensor which communicates the geolocation of each mobile tower 30. Other components of the irrigation system 12 may include location determining sensors as well. Alternatively, or additionally, the processing element 44 may perform calculations to determine geolocation data. For example, the processing element 44 may receive sensor information about the rotation angle between two or more mobile towers 30. The processing element 44 may then perform trigonometric or other mathematical calculations to determine the geolocation of each mobile tower 30. Or, the processing element 44 may perform dead reckoning calculations, which involve receiving measured distances traveled by each mobile tower 30 or other component, to determine the geolocation of each mobile tower 30 or other components.
The processing element 44 associates, correlates, or links the geolocation data to the sensor data and/or other input data. In one scenario, the processing element 44 may receive sensor data as a series of sampled data points from each sensor 16 while at the same time, or nearly the same time, the processing element 44 may receive, or calculate, geolocation data for the particular sensor 16. The processing element 44 links the sensor data with the geolocation data such that each digital data sample for each sensor 16 is linked with the geolocation sample for the sensor 16 at the time when the sensor sample was taken. For example, the processing element 44 may receive water pressure data as a series of sampled data points from a water pressure sensor at a particular mobile tower 30, while at the same time, or nearly the same time, the processing element 44 may receive geolocation data from a location determining sensor at the particular mobile tower 30. The processing element 44 then links the water pressure reading with the geolocation data and optionally a timestamp (time of day, date) as well. The linked input (sensor) data and geolocation data, along with optional timestamp data, is one piece of geospatial data. The processing element 44 may utilize the geospatial data interchange format based on JavaScript Object Notation (GeoJSON) to represent and process geospatial data.
The processing element 44 also receives geospatial data that includes geotechnical data, such as soil materials or composition, geological formations including rock or mineral deposits, elevational information identifying plains or hills, water features including rivers, streams, or ponds, and the like. All of the geotechnical data may already be linked or associated with geolocation data. The processing element 44 may link the geotechnical data with sensor data to form geospatial data. Thus, sensor data is linked with geolocation data, such as a latitude and longitude point, line, or area, and geotechnical data, such as soil composition and/or elevation.
The processing element 44 continues to receive both input data, such as sensor data, and geolocation data as time passes and the mobile towers 30 move over the land to be irrigated. The processing element 44 also continues to link the input data and geolocation data to create geospatial data. In some embodiments, the processing element 44 communicates (through the communication element 40) the geospatial data to the computer server 20. In other embodiments, after a certain minimum amount of data has been collected, the processing element 44 analyzes the geospatial data to determine trends, patterns, and/or anomalies in the geospatial data. In some embodiments, the processing element 44 analyzes the geospatial data to determine trends, patterns, and/or anomalies after one cycle of irrigation has occurred, wherein one cycle includes one full rotation of the conduit 26 in a circular, or near circular, central pivot irrigation system 12. One cycle of irrigation may include a full pass of the conduit 26 to cover the area of a linear or lateral irrigation system 12.
The analysis may include determining increases and/or decreases in the data from each sensor 16 or group of sensors 16. The increases and/or decreases may occur over distance, area, or space and/or over time. The analysis may also include determining, computing, or calculating statistics, such as a mean or average, a moving or windowed mean or average, a median, a standard deviation, and the like, for the data from each sensor 16 or group of sensors 16. The processing element 44 may also determine when an average for a sensor 16 or group of sensors 16 is changing or if the data for a sensor 16 or group of sensors 16 has values outside of the standard deviation of the data for the sensor 16 or group of sensors 16. For example, the processing element 44 may analyze the data from one or more sensors 16 that measure water pressure in the conduit 26 or other components of the irrigation system 12. The processing element 44 may determine when the water pressure has changes, such as steady or sharp decreases or increases.
In addition, the processing element 44 determines geospatial intersections, i.e., relationships between the trends in the sensor data with geolocation data and/or geotechnical data. When the processing element 44 determines or detects a change in the data for each sensor 16 or group of sensors 16, the processing element 44 also determines if the change in sensor data has a relationship, such as a positive correlation, with the geolocation data. For example, the processing element 44 may determine if the data for each sensor 16 or group of sensors 16 repeatedly changes in the same geolocation, such as a point or, more likely, an area of the land that is being irrigated. In one instance, the processing element 44 may determine an increase in drive motor electric current every time one or more mobile towers 30 are in a particular geolocation. This scenario may be indicative of a rut or gulley in the ground that the drive motors 36 of the mobile towers 30 have to work harder to get out of.
The processing element 44 may further analyze geotechnical data to determine relationships between the trends in the sensor data with geotechnical data or geological features. For example, the processing element 44 may determine if the data for a sensor 16 or group of sensors 16 repeatedly changes at certain elevations or changes in elevations. In one instance, the processing element 44 may determine a correlation between a repeated decrease in water pressure in the conduit 26 or other components and an increase in elevation, resulting from the mobile towers 30 moving up a hill. The processing element 44 may also determine if the data for a sensor 16 or group of sensors 16 repeatedly changes for certain types of soil composition. In another instance, the processing element 44 may determine a correlation between a repeated decrease in moisture level from ground sensors and the times when the mobile towers 30 travel over ground that has a dry or rocky soil composition.
The processing element 44 utilizes artificial intelligence (AI) and/or machine learning techniques or components to analyze the geospatial data to determine trends, patterns, and/or anomalies in the geospatial data. The geospatial data, including the sensor data and its linked geolocation data, is communicated to artificial intelligence and/or machine learning hardware units or software modules which analyze the geospatial data and identify trends or patterns in the geospatial data that indicate adjustments or changes to the operation of the irrigation system 12. The processing element 44 may utilize predictive analytics, artificial neural networks, convolutional neural networks, decision trees, or the like, or combinations thereof.
The processing element 44 also determines actions to take based on the determined trends, patterns, and/or anomalies in the geospatial data. The processing element 44 adjusts or changes the operation of components of the irrigation system 12. For example, based on the determination of a decrease in water pressure in the conduit 26 when the mobile towers 30 move up a hill, the processing element 44 may determine to increase the water pressure in the conduit 26 whenever the mobile towers 30 move to the geolocation area associated with the hill. As another example, based on the determination of a decrease in moisture level in dry or rocky soil, the processing element 44 may determine to slow down the mobile towers 30 whenever the mobile towers 30 pass through the geolocation area with the dry or rocky soil. Additionally or alternatively, the processing element 44 may determine to open additional valves 32 or otherwise increase water output whenever the mobile towers 30 pass through the geolocation area with the dry or rocky soil.

In embodiments in which the computing device 10 and the system controller 38 function as a single unit, the processing element 44 outputs a plurality of electronic signals, each electronic signal having an analog electric voltage or electric current level and/or digital data value. Each electronic signal is received by one or more of the electrically-controlled components of the irrigation system 12 such as the drive motors 36, the valves 32, and the pumps 34.
The processing element 44 outputs the electronic signal whose analog level or digital data value varies according to changes or adjustments that need to be made in the operation of various components based on the determined trends, patterns, and/or anomalies in the geospatial data. For example, the processing element 44 outputs the electronic signal to be received by the pumps 34, either directly or through the system controller 38, wherein the analog level or digital data value of the electronic signal instructs the pumps 34 to increase the water pressure to the conduit 26 or other components when the processing element 44 determines that the mobile towers 30 are moving up a slope. As another example, the processing element 44 outputs the electronic signal to be received by the drive motors 36 (or electronic control circuitry for the drive motors 36), either directly or through the system controller 38, wherein the analog level or digital data value of the electronic signal instructs the drive motors 36 to apply more torque to the wheels of the mobile towers 30 when the processing element 44 determines that the mobile towers 30 are in a geolocation area with a rut in the ground.
The processing element 44 also communicates data, including processed geospatial data, to the computer server 20 through the communication network 18. The processing element 44 may report any trends discovered in the geospatial data as well as any changes or adjustments to the operation of the components of the irrigation system 12. The computer server 20 may store the data and/or perform further processing.
Referring to step 101, sensor data is received from a plurality of sensors 16. The sensors 16 generally sense or detect performance quantities and/or operating parameters of various components of the irrigation system 12. For example, sensors, including potentiometers, rotary encoders, analog proximity sensors, analog laser proximity sensors, analog ultrasonic proximity sensors, or combinations thereof, may measure a rotational angle between two adjacent mobile towers 30 or sections of the conduit 26. Water gauges, including flow meters and the like, may measure the amount of water that has been applied to the crops during a certain time period. Pressure gauges may measure the water pressure at one or more points throughout the irrigation system 12. Tire pressure sensors may sense a plurality of pressures, one pressure associated with each tire utilized in the mobile towers 30 of the irrigation system 12. Electrical sensors, or electronic sensing circuitry, may sense a plurality of electric voltages and/or electric currents, one voltage and/or current associated with each drive motor 36 of the irrigation system 12. A gearbox sensor monitors or senses a status of the gearbox coupled to the drive motor 36. The gearbox sensor may include a plurality of sensors such as a temperature sensor, a pressure sensor, a viscosity sensor, a torque sensor, or any other suitable sensor. Sensors placed on the ground or elsewhere may sense or detect water that reaches the crops 14 in order to determine water application efficiency, or the water loss between the sprayers and the crops.
The sensors 16 may also sense or detect environmental quantities or conditions. For example, sensors may detect temperature, humidity, wind speed, air pressure, rain fall, available water, and the like. Alternatively, the computing device 10 may receive these values electronically from local atmospheric monitoring stations.
The sensors 16 may further include cameras capable of capturing images in the visible range, the near infrared range, the thermal infrared range, the short wave infrared range, and the like. Alternatively, the computing device 10 may receive these images electronically from satellite or other image capturing stations.
In addition, the sensors 16 may be able to determine topography or elevation of the land being irrigated as the irrigation system 12 moves across the land. Alternatively, the computing device 10 may receive topography or elevation data electronically from external sources.
Furthermore, the sensors 16 may be able to sense or determine a type of crops 14 that are being irrigated. Alternatively, the computing device 10 may receive crop information from a land manager, a farmer, or other external sources.
Referring to step 102, geolocation data is received or determined. The sensors 16 may include a location determining element configured to determine a current geolocation of one or more mobile towers 30 or components of the irrigation system 12. Alternatively, or additionally, the processing element 44 may perform calculations to determine geolocation data. For example, the processing element 44 may receive sensor information about the rotation angle between two or more mobile towers 30. The processing element 44 may then perform trigonometric or other mathematical calculations to determine the geolocation of each mobile tower 30. Or, the processing element 44 may perform dead reckoning calculations, which involve receiving measured distances traveled by each mobile tower 30 or other component, to determine the geolocation of each mobile tower 30 or other components.
Geotechnical data is also received. The geotechnical data may include soil materials or composition, geological formations including rock or mineral deposits, elevational information identifying plains or hills, water features including rivers, streams, or ponds, and the like. All of the geotechnical data may already be linked or associated with geolocation data.
Referring to step 103, data from each sensor 16 is linked with geolocation data to form geospatial data. The processing element 44 associates, correlates, or links the geolocation data to the input data. In one scenario, the processing element 44 may receive sensor data as a series of sampled data points from each sensor 16 while at the same time, or nearly the same time, the processing element 44 may receive, or calculate, geolocation data for the particular sensor 16. For example, the processing element 44 may receive water pressure data as a series of sampled data points from a water pressure sensor at a particular mobile tower 30, while at the same time, or nearly the same time, the processing element 44 may receive geolocation data from a location determining sensor at the particular mobile tower 30. The processing element 44 then links the water pressure reading with the geolocation data and optionally a timestamp (time of day, date) as well. The linked input (sensor) data and geolocation data, along with optional timestamp data, is one piece of geospatial data. The processing element 44 may utilize the geospatial data interchange format based on JavaScript Object Notation (GeoJSON).
The processing element 44 may also link the geotechnical data with sensor data to form geospatial data. Thus, sensor data is linked with geolocation data, such as a latitude and longitude point, line, or area, and geotechnical data, such as soil composition and/or elevation. In some embodiments, the method 100 may proceed from step 103 to step 107. In other embodiments, the method 100 may proceed from step 103 to step 104.
Referring to step 104, trends in the geospatial data for each sensor 16 or a group of sensors 16 are determined. The processing element 44 continues to receive both input data, such as sensor data, and geolocation data as time passes and the mobile towers 30 move over the land to be irrigated. The processing element 44 also continues to link the input data and geolocation data to create geospatial data. After a certain minimum amount of data has been collected, the processing element 44 analyzes the geospatial data to determine trends, patterns, and/or anomalies in the geospatial data. In some embodiments, the processing element 44 analyzes the geospatial data to determine trends, patterns, and/or anomalies after one cycle of irrigation has occurred, wherein one cycle includes one full rotation of the conduit 26 in a circular, or near circular, central pivot irrigation system 12. One cycle of irrigation may include a full pass of the conduit 26 to cover the area of a linear or lateral irrigation system 12.
The analysis may include determining increases and/or decreases in the data from each sensor 16 or group of sensors 16. The increases and/or decreases may occur over distance, area, or space and/or over time. The analysis may also include determining, computing, or calculating statistics, such as a mean or average, a moving or windowed mean or average, a median, a standard deviation, and the like, for the data from each sensor 16 or group of sensors 16. The processing element 44 may also determine when an average for a sensor 16 or group of sensors 16 is changing or if the data for a sensor 16 or group of sensors 16 has values outside of the standard deviation of the data for the sensor 16 or group of sensors 16. For example, the processing element 44 may analyze the data from one or more sensors 16 that measure water pressure in the conduit 26 or other components of the irrigation system 12. The processing element 44 may determine when the water pressure has changes, such as steady or sharp decreases or increases.
In addition, the processing element 44 determines geospatial intersections, i.e., relationships between the trends in the sensor data with geolocation data and/or geotechnical data. When the processing element 44 determines or detects a change in the data for each sensor 16 or group of sensors 16, the processing element 44 also determines if the change in sensor data has a relationship, such as a correlation, with the geolocation data. For example, the processing element 44 may determine if the data for each sensor 16 or group of sensors 16 repeatedly changes in the same geolocation, such as a point or, more likely, an area of the land that is being irrigated. In one instance, the processing element 44 may determine an increase in drive motor electric current every time one or more mobile towers 30 are in a particular geolocation. This scenario may be indicative of a rut or gulley in the ground that the drive motors 36 of the mobile towers 30 have to work harder to get out of.
The processing element 44 may further analyze geotechnical data to determine relationships between the trends in the sensor data with geotechnical data or geological features. For example, the processing element 44 may determine if the data for a sensor 16 or group of sensors 16 repeatedly changes at certain elevations or changes in elevations. In one instance, the processing element 44 may determine a correlation between a repeated decrease in water pressure in the conduit 26 or other components and an increase in elevation, resulting from the mobile towers 30 moving up a hill. The processing element 44 may also determine if the data for a sensor 16 or group of sensors 16 repeatedly changes for certain types of soil composition. In another instance, the processing element 44 may determine a correlation between a repeated decrease in moisture level from ground sensors and the times when the mobile towers 30 travel over ground that has a dry or rocky soil composition.
The processing element 44 utilizes artificial intelligence and/or machine learning techniques or components to analyze the geospatial data to determine trends, patterns, and/or anomalies in the geospatial data. The geospatial data, including the sensor data and its linked geolocation data, is communicated to artificial intelligence and/or machine learning hardware units or software modules which analyze the geospatial data and identify trends or patterns in the geospatial data that indicate adjustments or changes to the operation of the irrigation system 12. The processing element 44 may utilize predictive analytics, artificial neural networks, convolutional neural networks, decision trees, or the like, or combinations thereof.
Referring to step 105, changes or adjustments in an operation of components of the irrigation system based on trends determined in the geospatial data are determined. The processing element 44 also determines actions to take based on the determined trends, patterns, and/or anomalies in the geospatial data. The processing element 44 adjusts or changes the operation of components of the irrigation system 12. For example, based on the determination of a decrease in water pressure in the conduit 26 when the mobile towers 30 move up a hill, the processing element 44 may determine to increase the water pressure in the conduit 26 whenever the mobile towers 30 move to the geolocation area associated with the hill. As another example, based on the determination of a decrease in moisture level in dry or rocky soil, the processing element 44 may determine to slow down the mobile towers 30 whenever the mobile towers 30 pass through the geolocation area with the dry or rocky soil. Additionally or alternatively, the processing element 44 may determine to open additional valves 32 or otherwise increase water output whenever the mobile towers 30 pass through the geolocation area with the dry or rocky soil.
Referring to step 106, an electronic signal whose analog level or digital data value varies according to the changes or adjustments in the operation of components of the irrigation system is output. Referring to
In embodiments in which the computing device 10 and the system controller 38 function as a single unit, the processing element 44 outputs a plurality of electronic signals, each electronic signal having an analog electric voltage or electric current level and/or digital data value. Each electronic signal is received by one or more of the electrically-controlled components of the irrigation system 12 such as the drive motors 36, the valves 32, and the pumps 34.
The processing element 44 outputs the electronic signal whose analog level or digital data value varies according to changes or adjustments that need to be made in the operation of various components based on the determined trends, patterns, and/or anomalies in the geospatial data. For example, the processing element 44 outputs the electronic signal to be received by the pumps 34, either directly or through the system controller 38, wherein the analog level or digital data value of the electronic signal instructs the pumps 34 to increase the water pressure to the conduit 26 or other components when the processing element 44 determines that the mobile towers 30 are moving up a slope.
Referring to step 107, processed geospatial data is communicated to an external computer server 20. The processing element 44 also communicates data, including processed geospatial data, to the computer server 20 through the communication network 18. The processing element 44 may report any trends discovered in the geospatial data as well as any changes or adjustments to the operation of the components of the irrigation system 12.
The computing device 10 may further provide the following additional services, wherein the processing element 44 is further configured and/or programmed, via hardware, software, firmware, or combinations thereof, to perform the following operations and functions.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding a quantity, such as volume, of water or other fluid that has been applied to the soil corresponding to geospatial data. The processing element 44 may determine a volume of water, or trends in the volume of water, that has been applied to one or more geolocations for a given period of time. The processing element 44 may also determine, retrieve from the memory element 42, or retrieve from an external source, an optimal volume of water that should be applied to the geolocations for the period of time. The processing element 44 may compare measured data values of applied water volume, or trends in the measured data values of applied water volume, with optimal values of applied water volume. Based on, or according to, differences between the measured data, or trends in the measured data, and the optimal values, the processing element 44 may adjust the application rate of water in order to reduce the differences. The processing element 44 may adjust the application rate of water by adjusting the flow of water through the conduit 26 and/or sprayers or may adjust the speed of travel of the mobile towers 30. For example, if the processing element 44, based on measured data, or trends in the measured data, determines that too little water has been applied, the processing element 44 may increase the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34. The processing element 44 may also decrease the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36. Alternatively, if the processing element 44 determines that too much water has been applied, the processing element 44 may decrease the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34. The processing element 44 may also increase the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36. In any case, the processing element 44 may further adjust irrigation (water flow) start and stop times to increase or decrease the volume of water applied. The processing element 44 may have a watering schedule with time of day start and stop times or relative start and stop times, such as turning on irrigation for a first period of time and turning off irrigation for a second period of time, in order to provide the desired volume of water. If the desired volume of water is not being delivered, then the processing element 44 starts irrigation (by opening valves 32 and starting pumps 34) at an earlier time than was scheduled and/or stops irrigation (by closing valves 32 and stopping pumps 34) at a later time than was scheduled in order to increase the volume of water applied. On the other hand, the processing element 44 starts irrigation (by opening valves 32 and starting pumps 34) at a later time than was scheduled and/or stops irrigation (by closing valves 32 and stopping pumps 34) at an earlier time than was scheduled in order to decrease the volume of water applied.
The processing element 44 adjusts the operation of the valves 32, the pumps 34, and the drive motors 36 by adjusting data values, electric voltage and/or current levels, pulse width modulation values, or the like, or combinations thereof of electronic signals which are output to the components. In addition, the processing element 44 may adjust the operation of the components according to geospatial data, wherein adjustments may be made in some geolocations but not others, or different adjustments may be made in different geolocations.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding a pressure of the water or fluid in the irrigation system 12, such as in the conduit 26 and/or the sprayers, corresponding to geospatial data. In addition, or instead, the processing element 44 may determine geospatial data regarding the pressure of the water, or trends in the pressure of the water, in the irrigation system 12 for one or more geolocations for a given period of time. The processing element 44 may also determine, retrieve from the memory element 42, or retrieve from an external source, an optimal pressure of the water in the irrigation system 12 for the geolocations for the period of time. The processing element 44 may compare geospatial data including measured data values of irrigation system 12 water pressure, or trends in the measured data values of irrigation system 12 water pressure, with optimal values of irrigation system 12 water pressure. Based on, or according to, differences between the measured data, or trends in the measured data, and the optimal values, the processing element 44 may adjust the application rate of water in order to reduce the differences. The pressure of the water in the irrigation system 12 affects the application rate of the water in a direct manner. Typically, a lower than optimal water pressure results in a lower application rate, or underwatering, while a higher than optimal water pressure results in a higher application rate, or overwatering. According to geospatial data, the processing element 44 may adjust the application rate of water by adjusting the speed of travel of the mobile towers 30 or may adjust the flow of water through the conduit 26 and/or sprayers. For example, if the processing element 44, based on geospatial data including measured data, or trends in the measured data, determines that the pressure of the water in the irrigation system 12 is below a first threshold, then the processing element 44 may decrease the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36 to compensate for low water pressure. In addition, or instead, the processing element 44 may adjust the flow rate of the pumps 34 and/or change the settings of the valves 32 to increase the pressure of the water in the irrigation system 12, based on geospatial data. If the processing element 44 determines that the pressure of the water in the irrigation system 12 is above a second threshold, then the processing element 44 may increase the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36 to compensate for high water pressure. The processing element 44 may also or alternatively adjust the flow rate of the pumps 34 and/or change the settings of the valves 32 to decrease the pressure of the water in the irrigation system 12. In any case, the processing element 44 may further adjust irrigation start and stop times to compensate for water pressure that is not within normal parameters. The processing element 44 may adjust the operation of the components according to geospatial data, wherein adjustments may be made in some geolocations but not others, or different adjustments may be made in different geolocations.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding an alignment of the towers 30 corresponding to geospatial data, wherein the alignment refers to the angular relationship between two or more adjacent towers 30 relative to one another or one or more towers 30 relative to the center pivot 22. For example, as shown in
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding a pressure of the tires of the towers 30 corresponding to geospatial data. The processing element 44 may also determine geospatial data including trends in the pressure, such as decreasing pressure, of the tires of the towers 30 in the irrigation system 12. The processing element 44 may adjust the position of one or more towers 30, or the irrigation system 12 as a whole, according to geospatial data including the pressure, or trends in the pressure, of any of the tires of the towers 30. For example, if the pressure of one or more tires is less than a certain threshold, or if the trend of the pressure of one or more tires indicates a steady or rapid decrease, then the processing element 44 may position one or more towers 30 associated with the one or more low pressure tires in an area where access is good and service is easy to perform. In some instances, the processing element 44 may move the irrigation system 12 to the vicinity of a service road for ease of maintenance or repair. The processing element 44 may move the towers 30 and/or position the irrigation system 12 by controlling the operation of the drive motors 36.
The processing element 44 may further determine additional geospatial data including tire pressure values that are above a high threshold or below a low threshold which are associated with particular geolocations. The geospatial data may also include differential tire pressure values, that is a change in tire pressure, from one geolocation to a neighboring geolocation. The processing element 44 may determine the geolocations where any of the over-threshold conditions, such as tire pressure that is too high, too low, or greater than acceptable differential tire pressure, occur. The over-threshold conditions may be caused by tire ruts, differences in soil composition, differences in terrain, and so forth. The processing element 44 may adjust the operation of the irrigation system 12 to avoid the problematic geolocations. The processing element 44 may adjust the alignment of the towers 30 so that the tires avoid ruts or the like. Instead, or in addition, the processing element 44 may adjust the operation of the drive motors 36, such as by increasing the speed of the towers 30, to spend less time in the problematic geolocations.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding electrical characteristics, such as electric current flow, of the drive motors 36 corresponding to geospatial data. The processing element 44 may also determine geospatial data including trends in the electrical characteristic data, such as increasing electric current flow. The processing element 44 may adjust the position of one or more towers 30, or the irrigation system 12 as a whole, according to the electrical characteristic data, or trends in the electrical characteristic data, for any of the drive motors 36. An unexpected increase in electric current flow should be investigated. Thus, if the electric current flow through any one of the drive motors 36 exceeds a danger threshold, or if the trend of the electric current flow through any one of the drive motors 36 indicates a steady or rapid increase, then the processing element 44 may position one or more towers 30 associated with the problematic drive motor 36 in an area where access is good and service is easy to perform. The processing element 44 may also issue an electrical shutdown of the irrigation system 12.
The processing element 44 may further determine additional geospatial data including electric current values in one or more drive motors that are above a high threshold but below the danger threshold which are associated with particular geolocations. The high electric current values may be caused by similar issues as discussed above for tire pressure. That is, tire ruts, differences in soil composition, differences in terrain, and so forth. The processing element 44 may adjust the operation of the irrigation system 12 to avoid the problematic geolocations. The processing element 44 may adjust the alignment of the towers 30 to avoid the problematic geolocations. Instead, or in addition, the processing element 44 may adjust the operation of the drive motors 36, such as by increasing the speed of the towers 30, to spend less time in the problematic geolocations.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding water application efficiency of the irrigation system 12 corresponding to geospatial data. The water application efficiency relates to an amount of water that reaches the crops 14 versus an amount of water that is provided by the irrigation system 12 and may be determined or calculated as the volume of water received by the crops 14 divided by the volume of water delivered by the irrigation system 12. The processing element 44 may determine geospatial data including trends in the water application efficiency data for one or more geolocations for a given period of time. The processing element 44 may also determine, retrieve from the memory element 42, or retrieve from an external source, an optimal water application efficiency for the geolocations for the period of time. The processing element 44 may compare geospatial data including determined values of water application efficiency, or trends in the determined values of water application efficiency, with optimal values of water application efficiency. Based on, or according to, geospatial data including differences between the determined values, or trends in the determined values, and the optimal values, the processing element 44 may adjust the application rate of water in order to reduce the differences. Typically, the processing element 44 detects when the determined water application efficiency is less than optimal by greater than a certain amount. For example, if the optimal water application efficiency minus the determined water application efficiency is greater than a certain threshold for one or more geolocations, then the processing element 44 may decrease the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36 at those geolocations. In addition, or instead, the processing element 44 may increase the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34 at those geolocations. In any case, the processing element 44 may further adjust irrigation start and stop times to increase water application efficiency.
The processing element 44 receives a plurality of image data files, each encoding an image, from video sensors 16, such as cameras, or from external sources. The images may be captured in one or more of the following formats: near infrared (NIR), short-wave infrared (SWIR), red-green-blue (RGB), thermal, or the like. In addition, or instead, the processing element 44 may determine or receive a plurality of indices with formats such as enhanced vegetation index (EVI), normalized difference vegetation index (NDVI), or normalized difference moisture index (NDMI). Each index is derived from one or more images, typically in the visible red or infrared wavelength ranges, and has a numerical value which indicates the moisture level, the health, and/or density of vegetation of the crop 14. The images and indices may provide visual indications or evidence of vegetation growth and health. The images and indices may be of one or more crops, may cover one or more geolocations, and may be received periodically over a period of time. For example, the images and indices may be of one crop that is planted in one or more geolocations or one or more crops planted in a plurality of geolocations. The images and indices may be received at a rate of one image per hour, per day, per week, or the like for each geolocation over an extended period of time, such as a year. Using AI and/or other image analysis techniques, the processing element 44 may determine geospatial data including changes, trends, or anomalies in the images and indices over time for each geolocation, wherein the changes may indicate crop 14 growth and health.
In some embodiments, the processing element 44 may determine changes, trends, or anomalies in the images and indices over time by comparing the content of current images to the content of historical images. The processing element 44 makes adjustments to the operation of the irrigation system 12 according to the changes, trends, or anomalies in the images and indices. If the changes, trends, or anomalies in the images and indices indicate that a crop 14 is water stressed (i.e., a level of stress due to lack of water for the crop 14) in one or more geolocations, then the processing element 44 may decrease the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36 at those geolocations. In addition, or instead, the processing element 44 may increase the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34 at those geolocations. If the changes, trends, or anomalies in the images and indices indicate that a crop 14 is water stressed in one or more geolocations while the irrigation system 12 is not operating, i.e., spraying water, then the processing element 44 starts operation of the irrigation system 12.
In other embodiments, the processing element 44 may determine a temperature of the crop 14 and its surroundings from thermal images of the crop 14 in one or more geolocations. It has been demonstrated that a water stress level may be determined from a temperature of the crop 14, wherein there is generally a positive correlation between water stress level and temperature. That is, a higher temperature of the crop 14 indicates a higher water stress level, and a lower temperature of the crop 14 indicates a lower water stress level. In some embodiments, the water stress level may include or incorporate a crop water stress index (CWSI), which is determined by the processing element 44 from the determined temperatures of the crop 14 and its surroundings, such as the soil and canopy. In some instances, the water stress level may be determined as one of a plurality of grades or levels, such as low, medium, high, etc., given one or more temperatures from the crop 14 and its surroundings. In such instances, the water stress level may be determined from a lookup table, wherein the lookup table includes an entry for each water stress level and its associated temperature range. In other instances, the water stress level may be determined as a numerical value that is calculated from a mathematical equation as a function of one or more temperatures from the crop 14 and its surroundings or from the execution of an algorithm whose inputs include one or more temperatures from the crop 14 and its surroundings. The processing element 44 may also determine geospatial data including thermal data of the crop 14 and water stress level of the crop 14 over one or more geolocations.
The processing element 44 then determines an amount of water to apply, including a rate of water delivery, to the crop 14 according to the geospatial data including thermal data of the crop 14 and water stress level of the crop 14 over one or more geolocations. The amount of water may be determined from a lookup table, wherein the lookup table includes an entry for each water stress level and its associated amount of water to apply to the crop 14. Or, the amount of water may be determined from a mathematical equation as a function of the water stress level. Generally, there is a positive correlation between the amount of water to apply to the crop 14 and its water stress level. That is, a crop 14 with a higher water stress level requires more water, and a crop 14 with a lower water stress level requires less water. In order to apply or deliver the determined amount of water to the crop 14, the processing element 44 may adjust the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36. To increase the amount of water applied, the processing element 44 may adjust the speed of the appropriate drive motors 36 to slow the mobile towers 30 down. To decrease the amount of water applied, the processing element 44 may adjust the speed of the appropriate drive motors 36 to speed the mobile towers 30 up. In addition, or instead, the processing element 44 may adjust the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34 to adjust a flow rate of the water and/or a pressure of the water.
In addition, the processing element 44 may determine changes, trends, or anomalies in the images and indices over time for each geolocation in order to determine an amount of water that should be applied to the geolocations based on a level of health and/or growth of the crop 14. For example, changes, trends, or anomalies in the images and indices over time that indicate slow growth and/or poor health for one or more geolocations may require additional water to be applied. That is, for each crop 14, there may be an associated schedule of growth, wherein the crop should be one of a plurality of sizes over a plurality of periods of time during its lifespan. The size of the crop 14 may be determined from images and indices, wherein the size may be determined as a height of the crop 14, a width of the crop 14, a volume of the crop 14, or any other dimension that may be determined from the images and indices. Hence, after a first time period, such as one week after planting, the crop 14 should be of a first threshold size or size range, such as having a height of approximately one (1) inch or a range of approximately one (1) inch to approximately two (2) inches. After a second time period, such as two weeks after planting, the crop 14 should be of a second threshold size or size range, such as having a height of approximately two (2) inches or a range of approximately two (2) inches to approximately three (3) inches. The schedule of growth continues in the same fashion for additional periods of time. In certain embodiments, the schedule of growth of the crop 14 may vary according to geolocation. That is, the crop 14 in a first geolocation may have a first schedule of growth, while the crop 14 in a second geolocation may have a second schedule of growth. For each schedule of growth, the processing element 44 has a schedule of irrigation to achieve the level of growth at each time period, wherein the schedule may include times for irrigation and amounts of water to be delivered to the crop 14.
The processing element 44 compares the determined size of the crop 14 to the threshold size at each time period. If the size of the crop 14 is less than the threshold value at any time period, then the processing element 44 may decrease the speed of travel of the mobile towers 30 by adjusting the operation of the appropriate drive motors 36 at those geolocations. In addition, or instead, the processing element 44 may increase the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34 at those geolocations. On the other hand, changes, trends, or anomalies in the images and indices over time that indicate sufficient growth, that is, the crop 14 has a size that meets the threshold value at each period of time, and/or good health for one or more geolocations may require nominal or the water or less water to be applied. In those areas, the processing element 44 may make no change, or may adjust the operation of the appropriate drive motors 36, the valves 32, the pumps 34, or combinations thereof, to decrease the amount of water applied.
In any case, the processing element 44 may further adjust irrigation start and stop times to increase or decrease water application, as appropriate. The processing element 44 may have a watering schedule with time of day start and stop times or relative start and stop times, such as turning on irrigation for a first period of time and turning off irrigation for a second period of time, in order to provide the desired growth schedule of the crop 14. If the size of the crop 14 is less than the threshold value at any time period, then the processing element 44 starts irrigation (by opening valves 32 and starting pumps 34) at an earlier time than was scheduled and/or stops irrigation (by closing valves 32 and stopping pumps 34) at a later time than was scheduled in order to increase the volume of water applied. On the other hand, the processing element 44 starts irrigation (by opening valves 32 and starting pumps 34) at a later time than was scheduled and/or stops irrigation (by closing valves 32 and stopping pumps 34) at an earlier time than was scheduled in order to decrease the volume of water applied.
The processing element 44 receives data, measured from sensors 16 and/or received from other sources, regarding an elevation or topography of the land in which the crops 14 to irrigated are planted corresponding to geospatial data. The elevation of the land relates to increases and decreases of elevation, such as hills and valleys. Furthermore, the geospatial data links or associates the elevational data with geolocation data such that, for a plurality of geolocations within the area in which crops 14 are planted, the elevation of the land is known. The processing element 44 determines trends in the data system wide corresponding to the geospatial data. That is, the processing element 44 determines changes in the volume of water applied, the water application efficiency, the pressure of the water in the irrigation system 12, the electrical characteristics of the drive motors, the speed of the towers 30, the alignment of the towers 30, and the air pressure of the tires, among others, corresponding to the geospatial data. In particular, the processing element 44 may determine changes in any of the listed parameters, and others, that correspond to changes in elevation. Furthermore, the processing element 44 may determine whether the changes in any of the listed parameters affect the successful operation of the irrigation system 12, such as any of parameters falling below a critical threshold in relation to changes in elevation. Thus, the processing element 44 may adjust the operational parameters according to geospatial data, specifically, elevational data. For example, based on geolocation data, the processing element 44 may determine that a change in elevation is imminent if the towers 30 continue on their current trajectory. In anticipation, the processing element 44 may proactively increase or decrease the speed of the towers 30, increase or decrease the pressure of the water in the irrigation system 12, adjust the alignment of the towers 30, adjust irrigation start and stop times, and the like, in order to maintain operational parameters within acceptable levels as the irrigation system 12 approaches and passes through changes in elevation.
The processing element 44 receives data, measured from sensors 16, derived from environmental models, derived from images (such as those described above), or combinations thereof, regarding moisture or water that is within the soil and available to the crop 14. The processing element 44 may determine trends in the soil moisture data for one or more geolocations for a given period of time. The processing element 44 may adjust the application of water according to moisture levels in the soil. For example, if the processing element 44 determines the soil moisture level is low, or the trend in the soil moisture level is declining, for one or more geolocations, then the processing element 44 may increase the water application by increasing the amount of water that flows through the conduit 26 and/or sprayers and/or slowing down the towers 30 in the geolocations. If the processing element 44 determines the soil moisture level is high, or the trend in the soil moisture level is increasing, for one or more geolocations, then the processing element 44 may decrease the water application by decreasing the amount of water that flows through the conduit 26 and/or sprayers and/or speeding up the towers 30 in the geolocations. In any case, the processing element 44 may further adjust irrigation start and stop times to increase or decrease the volume of water applied. A variable rate irrigation (VRI) plan may be implemented to provide proper water application according to soil moisture levels in a plurality of geolocations.
The processing element 44 receives data, measured from sensors 16, derived from environmental models, derived from images (such as those described above), or combinations thereof, regarding an amount of rain that has fallen over a recent period of time for one or more geolocations. The processing element 44 may adjust the application of water according to the amount of rain fall, such as in units of inches or millimeters, that has occurred in one or more geolocations. For example, if the processing element 44 determines that rain has recently fallen in one or more geolocations, then the processing element 44 may decrease the application of water in the geolocations by decreasing the amount of water that flows through the conduit 26 and/or sprayers and/or speeding up the towers 30. The amount of water applied may vary according to the amount of rain that has fallen, wherein, generally, a larger amount of rainfall results in a smaller amount of water applied by the irrigation system 12 and a smaller amount of rainfall results in a larger amount of water applied. If the processing element 44 determines that rain has not fallen recently in one or more geolocations, then the processing element 44 may increase the application of water in the geolocations by increasing the amount of water that flows through the conduit 26 and/or sprayers and/or slowing down the towers 30. In any case, the processing element 44 may further adjust irrigation start and stop times to increase or decrease water application, as appropriate.
The processing element 44 receives mathematical models, indices, and data, measured from sensors 16, derived from environmental models, derived from images (such as those described above), or combinations thereof, regarding crops that are growing in one or more geolocations. The data may include crop type, crop vegetative cover, crop growth stage, planting date, plant variety, and so forth. The processing element 44 may adjust the application of water according to the crop data in one or more geolocations. For example, one type of crop 14 may generally require more water than another type of crop 14, and thus, water application is adjusted accordingly. In addition, application of water varies according to the growth stage of the crop 14. For example, corn, as a crop, has multiple vegetative growth stages and multiple reproductive growth stages. The mathematical model includes one or more equations that models the crop 14 and determines and/or predicts the growth stage of the crop 14 based on factors such as the type of the crop, the age of the crop, soil characteristics, environmental conditions, and so forth. Additionally, the mathematical model may include one or more coefficients, such as the crop coefficient Kc, which incorporates crop characteristics and averaged effects of evaporation from the soil. The processing element 44 may determine the growth stage from the mathematical model and/or from image or sensor data. Furthermore, the processing element 44 may determine geospatial data including the growth stage for one or more geolocations. Each growth stage may require a specific amount of water for the crop 14. Thus, the processing element 44 adjusts the application or delivery of water to the crop 14 according to the geospatial data. That is, the processing element 44 outputs a varying electronic signal to adjust the operation of the drive motors 36 of the mobile towers 30. In some cases, the processing element 44 outputs the varying electronic signal to decrease the speed of one or more mobile towers 30 to increase the amount of water applied in one or more geolocations. In other cases, the processing element 44 outputs the varying electronic signal to increase the speed of one or more mobile towers 30 to decrease the amount of water applied in one or more geolocations. In addition, or instead, the processing element 44 may adjust the amount of water that flows through the conduit 26 and/or sprayers by adjusting the operations of the valves 32 and/or the pumps 34. In some cases, the processing element 44 outputs the varying electronic signal to increase the amount of water that flows through the conduit 26 and/or sprayers by opening additional valves 32 and/or increasing the pressure of the pumps 34 in one or more geolocations. In other cases, the processing element 44 outputs the varying electronic signal to decrease the amount of water that flows through the conduit 26 and/or sprayers by closing some valves 32 and/or decreasing the pressure of the pumps 34 in one or more geolocations. Water application may be adjusted accordingly for other crop data as well.
Throughout this specification, references to “one embodiment”, “an embodiment”, or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment”, “an embodiment”, or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the current invention can include a variety of combinations and/or integrations of the embodiments described herein.
Although the present application sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent and equivalents. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Numerous alternative embodiments may be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.
Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein.
Certain embodiments are described herein as including logic or a number of routines, subroutines, applications, or instructions. These may constitute either software (e.g., code embodied on a machine-readable medium or in a transmission signal) or hardware. In hardware, the routines, etc., are tangible units capable of performing certain operations and may be configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as computer hardware that operates to perform certain operations as described herein.
In various embodiments, computer hardware, such as a processing element, may be implemented as special purpose or as general purpose. For example, the processing element may comprise dedicated circuitry or logic that is permanently configured, such as an application-specific integrated circuit (ASIC), or indefinitely configured, such as an FPGA, to perform certain operations. The processing element may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement the processing element as special purpose, in dedicated and permanently configured circuitry, or as general purpose (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the term “processing element” or equivalents should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which the processing element is temporarily configured (e.g., programmed), each of the processing elements need not be configured or instantiated at any one instance in time. For example, where the processing element comprises a general-purpose processor configured using software, the general-purpose processor may be configured as respective different processing elements at different times. Software may accordingly configure the processing element to constitute a particular hardware configuration at one instance of time and to constitute a different hardware configuration at a different instance of time.
Computer hardware components, such as communication elements, memory elements, processing elements, and the like, may provide information to, and receive information from, other computer hardware components. Accordingly, the described computer hardware components may be regarded as being communicatively coupled. Where multiple of such computer hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the computer hardware components. In embodiments in which multiple computer hardware components are configured or instantiated at different times, communications between such computer hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple computer hardware components have access. For example, one computer hardware component may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further computer hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Computer hardware components may also initiate communications with input or output devices, and may operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processing elements that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processing elements may constitute processing element-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processing element-implemented modules.
Similarly, the methods or routines described herein may be at least partially processing element-implemented. For example, at least some of the operations of a method may be performed by one or more processing elements or processing element-implemented hardware modules. The performance of certain of the operations may be distributed among the one or more processing elements, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processing elements may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processing elements may be distributed across a number of locations.
Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer with a processing element and other computer hardware components) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or a combination thereof), registers, or other machine components that receive, store, transmit, or display information.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
The patent claims at the end of this patent application are not intended to be construed under 35 U.S.C. § 112(f) unless traditional means-plus-function language is expressly recited, such as “means for” or “step for” language being explicitly recited in the claim(s).
Although the technology has been described with reference to the embodiments illustrated in the attached drawing figures, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the technology as recited in the claims.
Having thus described various embodiments of the technology, what is claimed as new and desired to be protected by Letters Patent includes the following:
