DETAILED DESCRIPTION
The present disclosure in one embodiment provides a methodology, a middleware component and/or software that controls which features on which devices are used based on a defined strategy such as energy savings or performance.
Given mobile solutions are built by assembling and integrating several sub-systems. For instance a mobile Geiger counter might contain a global positioning system (GPS) chip, sensor for making radiation measurements, a memory device for storing the measured radiation levels, a display unit for showing radiation levels in real-time, and a Bluetooth communication chip for wireless communications. The Geiger counter subsystem may also include battery and Wi-Fi (or like wireless communication) capability. An application generated may be made of individual parts or sub-systems integrated together, for instance, with multiple sensors, smartphone, and central processing unit, and so forth. The solution may be extended according to the specification with more and more sub-systems. For example, a smartphone with GPS, Wi-Fi and Bluetooth (or like short distance wireless communication technology) capabilities and battery may be considered another sub-system in the overall integrated system. Another sub-system could be a server which communicates with a plurality of Geiger counters, distributed within a city or in the country-side to interrogate readings from several independent Geiger counters. Pragmatically these parts have embedded capabilities such as GPS, wireless communication capabilities such as Bluetooth communication, Wi-Fi communication, and/or others. Those capabilities may work independently from one another, and may be activated or not activated. At time, these capabilities may be activated at the same time in different places and run redundantly, without being able to be controlled. In one embodiment of the present disclosure, a mechanism to control the activation and deactivation of those capabilities may be provided. Such mechanism may provide for savings of energy expanded in operating those features redundantly. For instance, redundantly activated or enabled capabilities may unnecessarily consume the energy and may as a consequence affect the overall system.
As these sub-systems may have been meant to be operated alone as independent devices, they may incorporate a set of capabilities that drain down the power source, for instance, if one does not pay attention to turn it off when not needed. The mechanism of the present disclosure may manage turning ON and OFF of those features automatically, while leaving some still ON to still support a service (GPS, for instance).
While assembling sub-systems (parts), one faces a challenge of deciding what features to keep ON and balancing activities according to remaining power. In one aspect, the mechanism of the present disclosure may manage and optimize the power or energy usage in a system made of a plurality of sub-systems, initially as well as during an on-going use of the system.
For example, the balancing of redundant capabilities in a system made up of, or comprising, sub-systems may be optimized. Sub-systems are also referred to as devices in the present disclosure. These sub-systems are taken out-of-the-box with their built-in functionality. In one exemplary example, a smart phone may communicate wirelessly via Bluetooth with a mobile Geiger counter. Both devices might contain GPS devices out-of-the box, since each could operate autonomously. These sub-systems are meant to not depend on other sub-systems. As a result of assembling those sub-systems (devices) into an overall system, some capabilities may become redundant or duplicated.
As an example, consider a target system (referred to as System A, for example) comprising two or more subsystems, for example, sub-system 1, sub-system 2, . . . , sub-system N. Consider that an example of the sub-system 1 is a smartphone, for example, used for its central processing unit (CPU), random access memory (RAM), and communication capabilities. FIG. 1 is a diagram illustrating an example sub-system with multiple capabilities. This example sub-system may be a smartphone. This sub-system may have the following capabilities: GPS 102 (Capability 1), Compass 104 (capability 2), Accelerometer 106 (Capability 3), Wi-Fi 108 (Capability 4), Bluetooth 110 (Capability 5). The total energy consumption EC of the target system (system A), may comprise the aggregation of energy consumption of individual capabilities in each of the sub-system making up the target system (system A). Referring to FIG. 1, GPS 102 has associated energy consumption (S1C1) 112, Compass 104 has associated energy consumption (S1C2) 114, Accelerometer 106 has associated energy consumption (S1C3) 116, Wi-Fi 108 has associated energy consumption (S1C4) 118, and Bluetooth 110 has associated energy consumption (S1C5) 120. The total energy consumption (EC1) of sub-system 1 (S1) 122 is the aggregation of each individual energy consumption (112, 114, 116, 118, 120).
FIG. 2 is a diagram illustrating another example sub-system with multiple capabilities. For example, the target system may also include sub-system 2 illustrated in FIG. 2. An example of sub-system 2 may be a carbon dioxide (CO2) sensor. This sub-system may have the following capabilities: CO2 sensing 202 (Capability 1), GPS 204 (capability 2), Wi-Fi 206 (Capability 3), Bluetooth 208 (Capability 4). CO2 sensing 202 has associated energy consumption (S2C1) 210, GPS 204 has associated energy consumption (S2C2) 212, Wi-Fi 206 has associated energy consumption (S2C3) 214, and Bluetooth 208 has associated energy consumption (S2C4) 216. The total energy consumption (EC2) of sub-system 1 (S2) 218 is the aggregation of each individual energy consumption (210, 212, 214, 216).
Yet another example of a sub-system may be a carbon monoxide (CO) sensor. Such CO sensor may comprise capabilities such as CO sensing, GPS, Bluetooth, and Accelerometer capabilities. Each of these capabilities has associated energy consumption level or amount.
The mechanism of the present disclosure provides for controlling which one or more of those capabilities in the sub-systems at any given point in time should be kept ON or OFF, for example, in order to save total energy consumption in the overall system.
The mechanism of the present disclosure in one embodiment may manage a list of all available features or capabilities in all the sub-systems (sub-system 1 to N) making up the overall system. A list of necessary features by an application (e.g., 1 GPS, 1 CO, 1 CO2, 1 Wi-Fi and 1 Accelerometer) may be also managed. A list of eligible features for controlling may be also generated. The energy status associated with all sub-systems (EC 1, EC 2, . . . , EC N) may be updated. Based on the list of eligible features and associated energy status, whether to turn those features ON or OFF may be determined.
Power (e.g., in Watts) is the product of the current draw of the items in a circuit (in Amps) multiplied by the voltage (in Volts). Many devices use the battery voltage directly. Batteries are rated in amp-hours. For instance an external battery pack for a smartphone might have a capacity of 8400 mA-hours (milliamp-hours) or 8.4 Amp-hours. That means that if the device draws 0.5 A, the battery will be depleted roughly after 16.8 hours. If the device draws 1 A, then the battery will only last 8.4 hours. The higher the current draw, the higher the power and the shorter the battery life.
Monitoring the power usage in a sub-system may be performed by monitoring the electrical current using an ammeter, for fixed voltage. The current draw may be measured by placing the ammeter in series with a battery terminal. The measurement (the magnitude of the current) may be “read” onboard. The measurement also may be sent wirelessly to an external computer or another device. The current draw (or power) from a single component may be determined by placing the ammeter in series with the power cable supplying power to each component. The current draw from a single component also may be determined by measuring the change in total power (at the battery) when a component is turned off or on. The power levels of components might not be constant. For instance, the GPS might draw a low value of current if it is not being asked to supply a latitude/longitude data, for instance, to an on-board device or a remote computer.
Each sub-system (for example, shown in FIG. 1 and FIG. 2) may be modified to allow for determining the current or power level of each component as described above. Each sub-system may be also provided with a switch to turn the individual component off or on.
FIG. 5 is a schematic diagram illustrating an example of a sub-system that comprises a plurality of components each attached to a power consumption measurement device, e.g., ammeter as described above. A power source 508 may provide power to the components (shown as capabilities). A capability 502 may be connected to a meter 506 (e.g., ammeter) that can measure its power consumption. The capability 502 may be turned ON or OFF with a switch 504, for example, by a processing unit 510 that executes an algorithm that turns ON and OFF the components as described herein. The processing unit 510 may receive instructions from a remote application or execute an intelligent algorithm locally for turning the components ON and OFF based on the measurements and/or measurements obtained from another sub-system. It is contemplated that the sub-system would have additional components and/or functionalities not shown in the figure for allowing proper functioning of the sub-system.
The power consumed by the components in the sub-systems may be monitored and one or more of the components switched ON and OFF dynamically. For example, consider an example of a Geiger counter and smartphone as two sub-systems in an overall system. Both have GPS components, and assuming that both GPSs are in proximity of each other in the overall system, the two GPSs would provide nearly identical location data. If one of the components is running low on power (e.g., because the smartphone is connected to Wi-Fi and is being used widely for phoning and texting), an on-board sensor may determine that the battery level is low on the smartphone, and dynamically shut down the smartphone's GPS to preserves its battery.
The power consumed by each similar component in the subsystems may be measured, and used in different ways. For example, an algorithm may be provided that can predict the energy savings when a redundant device is shut down. For instance, the amount of energy saved by turning off a component would be approximate to the measured power consumed by that individual component. In addition, which component or sub-system has lower energy consumption may be detected by using the individual component's power consumption.
Yet in another aspect, power consumption of a component may be controlled. For instance, the polling of the GPS device for location information may be controlled (e.g., the polling may be controlled to occur less frequently) to preserve battery power, for instance, if the available power level is running low. In another aspect, if the location were relatively constant, then the polling frequency could be reduced which would also save the battery.
An algorithm for determining which capability or feature, on which subsystem to turn ON or OFF may be as follows. Consider a Request Ri as the capabilities needed by the overall system i. Ri (GPS, Wi-Fi) notation represents a requirement of system i to have the GPS and Wi-Fi capabilities to be activated (turned ON).
Let's say Ri (GPS, Wi-Fi) represents a requirement for having ON (activated) the GPS and Wi-Fi capabilities in a system. A constraint in the algorithm may include making sure that for the same capacity (referred to as Cx), e.g., GPS or Wi-Fi, there is only one energy consumption (EC S (1 . . . N)) being expanded, i.e., only one of the same capacity is turned ON at any given point in time.
For example, given Ri (GPS, Wi-Fi), the algorithm activates only one GPS out of all GPS capabilities in sub-systems 1 . . . N at a given time. Referring to the example system comprising sub-systems of FIG. 1 and FIG. 2, one GPS capability would be activated out of GPS 102 and GPS 204. Similarly, only one Wi-Fi would be activated out of Wi-Fi 208 and Wi-Fi 206.
The management of the capability (function or feature) activation on different sub-systems may be based on one or more strategy or criterion. Further, in one embodiment of the present disclosure, after a certain time, sub-system activation may be switched to another of the same capabilities. For example, if a GPS function was delivered by sub-system 1 (FIG. 1 102), after a time period (e.g., based on a criterion), GPS capability at sub-system 1 (FIG. 1 102) may be turned OFF, and the same capability, GPS function at sub-system 2 (FIG. 2 204) may be turned ON. Alternating the activation of the same capability provided in different sub-systems avoids having to always have the same device ON.
The algorithm in one embodiment also dispatches energy consumption across sub-systems when the same capabilities are available in different sub-systems. Referring to the above example of Ri (GPS, Wi-Fi), the algorithm may activate one capability (e.g., GPS 102 in FIG. 1 or GPS 204 in FIG. 1) in one sub-system, while the other capability (e.g., Wi-Fi 206 in FIG. 2 or Wi-Fi 108 in FIG. 1) may be activated in another sub-system. Thus, the algorithm would avoid having both the GPS and Wi-Fi turned ON in on sub-system. In this way, not all required capabilities are run in one sub-system, and energy consumption may be dispatched across of all sub-systems.
The mechanism of the present disclosure may also include monitoring and evaluating over time the differences of energy consumption (EC) for same capability (Cx) by different sub-systems. The mechanism may activate as much as possible the SyCx combination consuming the least energy.
In addition, consideration may be taken into account that while new capabilities are integrated in the overall system, it is likely their associated technologies would be more efficient than old ones, and therefore more optimized. The mechanism of the present disclosure in one embodiment may over time activate the most efficient (e.g., best performance for saving energy) combination of sub-system capabilities.
In another aspect, the mechanism of the present disclosure may reactivate capabilities of a given sub-system (device) if its energy source increases its charge status. For instance, consider a device that is powered with solar cells. In determining whether to activate a capability from such a sub-system, overall energy use of that sub-system during the night time or cloudy periods when or where there less capacity for recharging the sub-system, may be taken into consideration. Similarly, use in sunlight or in the presence of battery power that was stored during a previous sunny period, may be taken into consideration. Likewise, consideration is taken into account of a sub-system that has or is prone to faster drainage of batteries or the like. Still yet, the mechanism of the present disclosure may consider the energy consumption evolution for the same capability by different sub-systems.
In one aspect, a remote application may be utilized to turn the components ON or OFF remotely. In another aspect, the components may be turned ON or OFF locally by an on-board application or the like.
FIG. 3 is a flow diagram illustrating a method for enabling one or more system capabilities in a system having a plurality of sub-systems in one embodiment of the present disclosure. The sub-systems are distinct devices, for instance, to be run independently without depending on another device in the system. For example, the system may include a first device (sub-system) comprising a first set of capabilities, a second device (sub-system) comprising a second set of capabilities. The sub-systems have at least one overlapping capability. At 302, the method may comprise obtaining a list of sub-systems in the system and one or more capabilities provided in the sub-systems. For instance, the method may comprise receiving information associated with the first device and the first set of capabilities, and information associated with the second device and the second set of capabilities may be received. At 304, one or more required capabilities for the system that need to be activated is determined or obtained. The required capabilities may be obtained from a user. In another aspect, the required capabilities may be automatically determined, for example, based on the functionalities and purposes of each of the sub-systems in the system, and/or other considerations.
At 306, for each required capability, one sub-system from the list of sub-systems that provides the required capability is selected for activation of that capability. For instance, based on the information received and one or more criteria, the method may automatically select which capability from the first device and the second device to activate to satisfy the one or more required capabilities of the system. For example, as discussed above, a sub-system (or device) that provides the capability with the least energy usage in providing that capability, as well as currently having the least total energy usage may be selected. Other criteria may include one or more of minimizing total energy use in each of the sub-systems, minimizing total energy use in the system, distributing activation of said each of the one or more required capabilities across said sub-systems, for instance, in a balanced manner, so that not all of the required capabilities are activated on one sub-system. Other considerations may be taken into account when selecting a sub-system (device) on which to run (activate) the required capability.
At 308, the one or more required capabilities may then be automatically activated on the one or more selected sub-systems. For instance, the selected capability is activated in the first device or the second device. In another aspect, the same capability present in the sub-systems not selected (hence redundant), may be automatically deactivated on those not-selected subsystems, if not already deactivated. In another aspect, before automatically activating the capability in the selected sub-system, a user may be asked to confirm the activation. Examples of capabilities may include, but are not limited to, location-aware CO2 sensor, navigation system, radiation sensor, magnetic field sensor, and noise (dB) sensor.
As described above, the activation of the capabilities in different sub-systems may change over time automatically, for example, based on continuous or periodic monitoring and evaluating. For example, the energy usage in the one or more sub-systems may be checked to determine whether a required capability should be activated on a different sub-system, for example, based on the current energy usage of the selected sub-system. For instance, if the sub-system having the required capability activated currently is being drained of power (e.g., as determined by a threshold value), the mechanism of the present disclosure may re-evaluate another sub-system that provide the same capability, and may decide to activate the capability on that another sub-system rather than the current one. Thus, for example, the method may return to 306 to re-determine which of the capabilities should be run on which of the sub-systems.
Yet in another aspect, the list of subsystems in the system may change, for example, as the system may be integrated with more subsystems. In addition, the one or more required capabilities for the system may also change. The method in one embodiment utilizes the updated list of subsystems and the required capabilities in performing its functions at 306 and 308.
FIG. 6 is a high-level block diagram illustrating an overall target system of the present disclosure in one embodiment. The overall system may comprise two or more devices, e.g., referred to also as sub-systems (e.g., 604, 606). Each of the devices may comprise a plurality of capabilities, e.g., as shown and described with reference to FIGS. 1 and 2 above. Each of the devices has its own built-in functionality and functions on its own, for example, without any dependence on other devices. For instance, devices are built to be distinct and are not intended (at least initially when built) to operate in coordination with another device. In one embodiment of the present disclosure, such plurality of devices is managed by a middle layer (e.g., software application) 602 or the like, so as to optimize the usage and power consumption of the capabilities in the devices making up the overall target system. The middle layer 602 of the present disclosure in one embodiment coordinates and/or control the workings (e.g., which capabilities are activated or not activated) of those devices. In one aspect, the middle layer 602 of the present disclosure acts as an operating system between two or more distinct devices, to monitor components' power consumptions and shut selective components off, based on the monitoring and/or one or more other criteria or algorithms, for example, dynamically, for example, as described above. In one embodiment of the present disclosure, more devices may be adaptively and/or dynamically added into the overall target system for the middle layer 602 to manage. The middle layer 602 may receive information associated with the capabilities of each of the devices (e.g., 604, 606), and which capabilities are required in the overall target system. The power consumption associated each of the capabilities in each of the devices may be measured and monitored. Based on at least the information and the monitored power consumption, the middle layer 602 may select which components on which devices can be shut off, and still yet have the overall system provide the required capabilities (or functionalities) by the devices. In one embodiment of the present disclosure, the monitoring of power consumption may be performed on an on-going basis, e.g., continuously or continually (periodically), and the selecting which of the components (capabilities) to turn ON or OFF, may be performed dynamically based on the current status of the power consumption (e.g., in each of the devices) and/or other criterion in the overall target system. The middle layer 602 may communicate with the devices 604, 606 using wireless and/or wired communication methods. Hence, the middle layer 602 may be located remotely from the devices making up the overall target system. In another embodiment, the middle layer 602 may reside with the devices making up the overall target system.
FIG. 4 illustrates a schematic of an example computer or processing system that may implement a system in one embodiment of the present disclosure. The computer system is only one example of a suitable processing system and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the methodology described herein.

Such communication can occur via Input/Output (I/O) interfaces 20.
Still yet, computer system can communicate with one or more networks 24 such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 22. As depicted, network adapter 22 communicates with the other components of computer system via bus 14. It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system. Examples include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc.
