Exemplary Arrangements of User Device Components
FIGS. 3A and 3B are diagrams of exemplary arrangements 300 of components of user device 100. As illustrated in FIG. 3A, processing logic 210 may communicate with batteries 260-1, . . . , 260-N (collectively referred to as “batteries 260”) monitoring device(s) 270, and/or device component(s) 310. Batteries 260-1, . . . , 260-N may include the features described above in connection with batter(ies) 260 shown in FIG. 2. Device component(s) 310 may include any component (or combination of components) included in user device 100 (e.g., circuits, memory 220, user interface 230, communication interface 240, antenna assembly 250, etc.). In one implementation, batteries 260 may be included in device component(s) 310. Arrangement 300 depicted in FIG. 3A may permit certain batteries 260 to energize device component(s) 310 based on one or more conditions measured by monitoring device(s) 270.
In one implementation, monitoring device(s) 270 may measure one or more conditions (e.g., a temperature) of one or more of device component(s) 310, and/or may provide the measured one or more conditions to processing logic 210. Processing logic 210 may determine whether the measured one or more conditions is below or above a threshold. For example, processing logic 210 may determine whether a measured temperature of one of device component(s) 310 is below a low temperature threshold (e.g., dependent on user device 100) or above a high temperature threshold (e.g., dependent on user device 100). If processing logic 210 determines that the measured condition of one of device component(s) 310 is below or above the threshold, processing logic 210 may instruct activation of one or more of batteries 260 based on the measured condition. For example, batteries 260 may include batteries with certain operating temperature ranges (e.g., batteries with overlapping operating temperature ranges). Processing logic 210 may select one or more of batteries 260 (e.g., one or more of batteries 260 with an operating temperature range that contains the measured temperature) for activation based on the measured temperature. Such overlapping operating temperature ranges may increase a temperature window of operation for device component(s) 310 and/or user device 100. Batteries 260 that receive instructions for activation from processing logic 210 may be activated for energizing one or more of device component(s) 310 of user device 100. In one example, a low-temperature battery (e.g., one of batteries 260) may be used as a main battery in extreme cold conditions.
As shown in FIG. 3B, processing logic 210 may communicate with batteries 260-1, . . . , 260-N (collectively referred to as “batteries 260”) monitoring device(s) 270, and/or device component(s) 310. One or more of batteries 260 may connect to a corresponding management device 280-1, . . . , 280-N (collectively referred to as “management devices 280”). Management devices 280-1, . . . , 280-N may include the features described above in connection with management device(s) 280 shown in FIG. 2. Arrangement 300 depicted in FIG. 3B may permit certain batteries 260 to energize one or more management devices 280 based on one or more conditions measured by monitoring device(s) 270.
In one implementation, monitoring device(s) 270 may measure one or more conditions (e.g., a temperature) of one or more of device component(s) 310, and/or may provide the measured one or more conditions to processing logic 210. Processing logic 210 may determine whether the measured one or more conditions is below or above a threshold. For example, processing logic 210 may determine whether a measured temperature of one of device component(s) 310 is below a low temperature threshold (e.g., a threshold that may depend on user device 100) or above a high temperature threshold (e.g., a threshold that may depend on user device 100). If processing logic 210 determines that a measured condition of one of device component(s) 310 is below or above the threshold, processing logic 210 may instruct activation of one or more of batteries 260 based on the measured condition. Batteries 260 that receive instructions for activation from processing logic 210 may be activated for energizing and/or activating one or more of management devices 280. The activated management devices 280 may manage the one or more conditions of device component(s) 310.
For example, management device(s) 280 may be thermal management devices and may be used for active thermal management (e.g., heating in cold temperature conditions, or cooling in hot temperature conditions) of device component(s) 310 and/or user device 100. In another example, a low-temperature battery (e.g., one of batteries 260) may be used in conjunction with one of management device(s) 280 (e.g., a heating element) to heat a standard-temperature battery. In still another example, management devices 280 (e.g., a cooling device) may be used to cool a battery (e.g., one of batter(ies) 260) that is at too high of a temperature or is overheating in order to reduce a safety hazard.
Although FIGS. 3A and 3B show exemplary components and component arrangements of user device 100, in other implementations, user device 100 may contain fewer, different, or additional components and/or arrangements than depicted in FIGS. 3A and 3B. In still other implementations, one or more components of user device 100 may perform one or more other tasks described as being performed by one or more other components of user device 100.

FIG. 4 is an exemplary diagram of monitoring device(s) 270. As illustrated, monitoring device(s) 270 may include a voltage monitoring device 400, a temperature monitoring device 410, and/or a drop monitoring device 420.
Voltage monitoring device 400 may include any device capable of measuring voltages of one or more of batter(ies) 260. For example, in one implementation, voltage monitoring device 400 may include a voltmeter, a potentiometer, an A/D converter provided within user device 100, etc. In other implementations, voltage monitoring device 400 may include other components of user device 100 that are capable of measuring voltage of battery 260, such as processing logic 210. As further shown in FIG. 4, voltage monitoring device 400 may measure a battery voltage 430, and may output a measured voltage 460 to processing logic 210. Processing logic 210 may utilize measured voltage 460 to activate one or more of batter(ies) 260 that may be dedicated for managing conditions of user device 100. For example, if a decrease in measured voltage 460 indicates that user device 100 and/or one or more of device component(s) 310 are overheating, processing logic 210 may activate one or more of management device(s) 280 (e.g., via activation of one or more of batter(ies) 260) to cool user device 100 and/or one or more of device component(s) 310.
Temperature monitoring device 410 may include any device capable of measuring temperatures of one or more components of user device 100 (e.g., batter(ies) 260, device component(s) 310, etc.) and/or user device 100. For example, in one implementation, temperature monitoring device 410 may include a thermometer, a thermocouple, a thermistor, a resistance temperature detector (RTD), etc. As further shown in FIG. 4, temperature monitoring device 410 may measure a temperature 440 of one or more components of user device 100 (or a temperature of user device 100), and may output a measured temperature 470 to processing logic 210. Processing logic 210 may utilize measured temperature 470 to activate one or more of batter(ies) 260 that may be dedicated for managing conditions (e.g., temperatures) of user device 100. For example, if an increase in measured temperature 470 indicates that user device 100 and/or one or more of device component(s) 310 are overheating, processing logic 210 may activate one or more of management device(s) 280 (e.g., via activation of one or more of batter(ies) 260) to cool user device 100 and/or one or more of device component(s) 310.
Drop monitoring device 420 may include any device capable of measuring various mechanical conditions (e.g., dropping, shaking, striking, etc.) of one or more of batter(ies) 260 and/or user device 100. For example, in one implementation, drop monitoring device 420 may include an accelerometer, a Doppler receiver, a GPS receiver, etc. As further shown in FIG. 4, drop monitoring device 420 may measure a battery drop 450 (or a drop of user device 100), and may output a measured drop 480 to processing logic 210. Processing logic 210 may utilize measured drop 480 to activate one or more of batter(ies) 260 that may be dedicated for managing conditions of user device 100. For example, if a value of measured drop 480 indicates that user device 100 and/or one or more of device component(s) 310 are damaged and overheating, processing logic 210 may activate one or more of management device(s) 280 (e.g., via activation of one or more of batter(ies) 260) to cool user device 100 and/or one or more of device component(s) 310.
Although FIG. 4 shows exemplary components of monitoring device(s) 270, in other implementations, monitoring device(s) 270 may contain fewer, different, or additional components than depicted in FIG. 4. In still other implementations, one or more components of monitoring device(s) 270 may perform one or more other tasks described as being performed by one or more other components of monitoring device(s) 270.
Exemplary Processes
FIG. 5 depicts a flow chart of an exemplary process 500 for providing thermal management of user device 100. In one implementation, process 500 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210). In other implementations, process 500 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210) in combination with hardware and/or software components of another device (e.g., communicating with user device 100 via communication interface 240).
As illustrated, process 500 may begin with a temperature measurement of a component of a user device (block 510), and/or a determination of whether the measured temperature is below or above a temperature threshold (block 520). For example, in one implementation described above in connection with FIG. 3B, monitoring device(s) 270 of user device 100 may measure one or more conditions (e.g., a temperature, measured voltage 460, measured drop 480, etc.) of one or more of device component(s) 310, and/or may provide the measured one or more conditions to processing logic 210. Processing logic 210 may determine whether the measured one or more conditions is below or above a threshold. In one example, processing logic 210 may determine whether a measured temperature of one of device component(s) 310 is below a low temperature threshold (e.g., a threshold that may depend on user device 100) or above a high temperature threshold (e.g., a threshold that may depend on user device 100). In one implementation, the low temperature threshold and/or the high temperature threshold may be configurable.
Returning to FIG. 5, if the measured temperature is below or above the temperature threshold (block 520—YES), a battery of the user device may be activated (block 530). Otherwise (block 520—NO), process 500 may return to block 510. For example, in one implementation described above in connection with FIG. 3B, if processing logic 210 determines that a measured condition (e.g., a temperature) of one of device component(s) 310 is below or above the threshold (e.g., a temperature threshold), processing logic 210 may instruct activation of one or more of batteries 260 based on the measured condition. Batteries 260 that receive instructions for activation from processing logic 210 may be activated.
As further shown in FIG. 5, a temperature management device connected to the activated battery may be activated (block 540), and/or the temperature management device may manage the temperature of the component of user device (block 550). For example, in one implementation described above in connection with FIG. 3B, activated batteries 260 may energize and/or activate one or more of management devices 280. The activated management devices 280 may manage the one or more conditions of device component(s) 310. In one example, management device(s) 280 may be thermal management devices and may be used for active thermal management (e.g., heating in cold temperature conditions, or cooling in hot temperature conditions) of device component(s) 310 and/or user device 100. In another example, a low-temperature battery (e.g., one of batteries 260) may be used in conjunction with one of management devices 280 (e.g., a heating element) to heat a standard-temperature battery.
FIG. 6 depicts a flow chart of an exemplary process 600 for activating one of batteries 260 of user device 100 based on a measured condition (e.g., a temperature, measured voltage 460, measured drop 480, etc.). In one implementation, process 600 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210). In other implementations, process 600 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210) in combination with hardware and/or software components of another device (e.g., communicating with user device 100 via communication interface 240).
As illustrated, process 600 may begin with measurement of a temperature and/or a condition of a user device and/or a component of the user device (block 610). For example, in one implementation described above in connection with FIG. 3A, monitoring device(s) 270 of user device 100 may measure one or more conditions (e.g., a temperature) of user device 100 and/or one or more of device component(s) 310, and/or may provide the measured one or more conditions to processing logic 210.
Returning to FIG. 6, a battery, from batteries with overlapping temperature ranges, may be determined based on the measured temperature and/or condition (block 620), and/or the determined battery may be activated (block 630). For example, in one implementation described above in connection with FIG. 3A, batteries 260 of user device 100 may include batteries with certain operating temperature ranges (e.g., batteries with overlapping operating temperature ranges). Processing logic 210 may select one or more of batteries 260 (e.g., one or more of batteries 260 with an operating temperature range that contains the measured temperature) for activation based on the measured temperature. Batteries 260 that receive instructions for activation from processing logic 210 may be activated for energizing one or more of device component(s) 310 of user device 100. In one example, a low-temperature battery (e.g., one of batteries 260) may be used as a main battery in extreme cold conditions.
FIG. 7 depicts a flow chart of an exemplary process 700 for managing a condition of user device 100 via activation of batteries 260 of user device 100. In one implementation, process 700 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210). In other implementations, process 700 may be performed by hardware and/or software components of user device 100 (e.g., processing logic 210) in combination with hardware and/or software components of another device (e.g., communicating with user device 100 via communication interface 240).
As illustrated, process 700 may begin with a measurement of a condition of a user device and/or a component of the user device (block 710), and/or a determination of a battery dedicated for management based on the measured condition (block 720). For example, in one implementation described above in connection with FIG. 3B, monitoring device(s) 270 of user device 100 may measure one or more conditions (e.g., a temperature, measured voltage 460, measured drop 480, etc.) of user device 100 and/or one or more of device component(s) 310, and/or may provide the measured one or more conditions to processing logic 210. Processing logic 210 may select one or more of batteries 260 (e.g., one or more of batteries 260 dedicated for management of user device 100) for activation based on the measured one or more conditions.
Returning to FIG. 7, the determined battery may be activated (block 730), and/or a management device connected to the determined battery may be activated (block 740). For example, in one implementation described above in connection with FIG. 3B, batteries 260 that receive instructions for activation from processing logic 210 may be activated for energizing and/or activating one or more of management devices 280.
As further shown in FIG. 7, the activated management device may manage the user device and/or the component of the user device (block 750). For example, in one implementation described above in connection with FIG. 3B, the activated management devices 280 may manage the one or more conditions of user device 100 and/or device component(s) 310. In one example, management device(s) 280 may be thermal management devices and may be used for active thermal management (e.g., heating in cold temperature conditions, or cooling in hot temperature conditions) of user device 100 and/or device component(s) 310. In another example, a low-temperature battery (e.g., one of batteries 260) may be used in conjunction with one of management devices 280 (e.g., a heating element) to heat a standard-temperature battery.
CONCLUSION
Implementations described herein may provide systems and/or methods for activating one or more batteries of a user device based on one or more measured conditions of the user device. For example, in one implementation, a temperature of the user device and/or a component of the user device may be measured, and/or one or more batteries (e.g., batteries that may be used in extreme temperature (heat or cold) conditions) may be determined based on the measured temperature. The determined one or more batteries may be activated and/or may provide a better resistance to the measured temperature. In another example, one or more batteries (e.g., batteries dedicated for thermal management of the user device) may be determined based on the measured temperature, and/or may be activated. The determined one or more batteries may activate corresponding management devices (e.g., thermal management devices), and/or the corresponding management devices may manage (e.g., control the temperature) the user device and/or the component of the user device.
The foregoing description of implementations provides illustration and description, but is not intended to be exhaustive or to limit the invention to the precise form disclosed. Modifications and variations are possible in light of the above teachings or may be acquired from practice of the invention. For example, while series of blocks have been described with regard to FIGS. 5-7, the order of the blocks may be modified in other implementations. Further, non-dependent blocks may be performed in parallel.
It should be emphasized that the term “comprises/comprising” when used in the this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
It will be apparent that aspects, as described above, may be implemented in many different forms of software, firmware, and hardware in the implementations illustrated in the figures. The actual software code or specialized control hardware used to implement these aspects should not be construed as limiting. Thus, the operation and behavior of the aspects were described without reference to the specific software code—it being understood that software and control hardware could be designed to implement the aspects based on the description herein.
Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the invention. In fact, many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification.
No element, block, or instruction used in the present application should be construed as critical or essential to the invention unless explicitly described as such. Also, as used herein, the article “a” is intended to include one or more items. Where only one item is intended, the term “one” or similar language is used. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
