Description

POWER CONSUMPTION REPORT THROUGH AN ACCESSORY OF AN ELECTRONIC DEVICE BACKGROUND OF THE INVENTION Technical Field of the Invention The present invention is generally related to the field of power consumption in portable electronic devices, and in particular, by means of an example but not limited to the determination of remaining battery power when one or More accessories are connected to a mobile terminal or other electronic device.

Description of Related Art Many types of electronic devices use battery power instead of or in addition to a plug's A / C power. For example, laptops, mobile terminals, video recorders, etc. They usually operate with battery power. Some of these electronic devices (e.g., especially mobile terminals) attempt to communicate to the user the remaining time during which the electronic device can be operated using the current battery before the battery is completely depleted (or virtually completely). Users of mobile terminals and other electronic devices typically want to know the remaining operational time with a battery installed in order to properly plan the eventual depletion of the battery and the consequent loss of operation of the device. For example, a user of a mobile terminal may wish to terminate a current call, arrive at a destination by car, transmit a document, or otherwise appropriately budget the rest of the battery life in order to fulfill a desired objective. The user of a VCR, as an additional example, may wish to complete the recording of a special event, watch a video in a remote location, etc. Examples of known apparatus that detect and indicate the capacity of the remaining battery of an electronic device include US Pat. Nos. 5,608,324; 5,654,623, and 5,739,674 and European Publication No. EP 0845682 A2. As indicated in the aforementioned documents, providing the user with an accurate calculation of the remaining life of the battery requires that a power consumption of current be determined. This determination, however, can be difficult, especially since the number and type of power consumption and an electronic device vary. Therefore, there is a need that until now has not been recognized (much less satisfied), to determine an exact current consumption of the battery of an electronic device when the electronic device is connected to one or more accessories that also extracts power from the Electronic device battery so that you can accurately predict the remaining life of the battery. There is also the need that until now has not been recognized (much less satisfied), to inform the remaining life of the battery of a battery of an accessory, especially for those accessories that lack the ability to directly communicate the remaining life of the battery to the user.

COMPENDIUM OF THE INVENTION The deficiencies of the prior art are solved by the method, system and apparatus of the present invention. For example, since until now it has not been recognized, it would be beneficial if an electronic device were aware of the current consumption by means of a connected accessory in order to be able to properly calculate an operational remaining time of the battery of the electronic device. In fact, it would be beneficial if the accessory connected to the electronic device could communicate with the electronic device by providing information representative of the current consumption by the connected accessory. In one embodiment, the accessory is connected to an electronic device and derives power from a battery of the electronic device. The accessory provides information regarding the power consumed by the attachment to the electronic device. The electronic device can then include the information in a determination of remaining battery life, which can be subsequently communicated to the user. In an alternative of this modality, the accessory verifies its operational parameters and derives a current draw from it. This current extraction is reported to the electronic device. Other alternatives will be described later in the Detailed Description. In another embodiment, the accessory is connected to an electronic device, but the accessory has access to an independent power supply (for example, including its own battery). If the accessory does not have the ability to communicate directly to the user the remaining life of the battery of its battery, then the accessory can communicate information regarding the remaining life of the battery to the electronic device, which subsequently communicates the remaining life of the battery. user accessory battery. This information can be provided in many ways, as will be explained in detail later. The technical advantages of the present invention include, but are not limited to the following. It should be understood that the particular modalities may not imply any, much less all the following exemplary technical advantages. An important technical advantage of the present invention is that it allows a more accurate calculation of the remaining life of the battery of the electronic device to be had. Another important technical advantage of the present invention is that it provides the ability to calculate the total power consumption of both the electronic device and the accessory connected to the electronic device. Yet another important technical advantage of the present invention is that it improves the calculation of standby time in, for example, an electronic mobile terminal device. Yet another important technical advantage of the present invention is the ability to optimally communicate to the user the remaining life of the battery for an accessory that may be unable to directly communicate the remaining life of the battery to the user. The above-described features and other features of the present invention will be explained in detail below with reference to the illustrative examples shown in the accompanying drawings. Those skilled in the art will appreciate that the embodiments described are provided for purposes of illustration and understanding and that several equivalent embodiments are contemplated herein. It should be emphasized that the term "comprises / understanding" when used in this specification is taken to specify the presence of established characteristics, integrals, steps, components, etc., but the term does not exclude the presence or addition of one or more than the other characteristics, integrals, steps, components, groups of the same, etc.

DETAILED DESCRIPTION OF THE DRAWINGS In the following description, for purposes of explanation and not limitation, specific details are established, such as particular circuits, logic modules (implemented in, for example, software, hardware, firmware, etc.), techniques, etc. in order to provide a complete understanding of the invention. However, it will be apparent to those of ordinary skill in the art that the present invention can be practiced in other modalities that do not depart from these specific details. In other cases, detailed descriptions of well-known methods, devices, logical codes (hardware, software, firmware, etc.), etc. they are omitted so as not to obscure the description of the present invention with unnecessary details.

A preferred embodiment of the present invention and its advantages are best understood by reference to the FIGURES 1-6B of the drawings, similar numbers are used for similar and corresponding parts of the different drawings. A deficiency with respect to an electronic device that determines only the power it consumes when calculating the remaining life of the battery is that some accessories also use the battery of the electronic device as a power supply. When the electronic device does not know how much current the accessory consumes, the accuracy of the calculated power consumption will consequently be too low. Certain embodiments of the present invention allow calculation of the total power consumption for both the electronic device and the accessory that is connected thereto. It should be understood that while exemplary embodiments are described in terms of a mobile terminal (e.g., a wireless mobile station, a computer with a wireless link, etc.), the present invention can be applied equally to electronic devices in general. further, aspects of the Global System for Mobile Communication (GSM). the wireless network standards will be used to describe one embodiment of the present invention. However, it should be understood that the principles of the present invention can be applied (in addition to other wireless communication standards (or systems)) to electronic devices in general, including those that are battery powered and to which accessories can be connected. that share the battery of the electronic device. It should be noted that accessories for a mobile terminal may include but are not limited to portable hands-free attachments, infrared (IR) plugs, vibration notification attachments, etc. It should also be noted that the accessory (eg, a search engine, etc.) may alternatively be physically located within the housing of a battery that supplies power to the mobile terminal or to another electronic device and removably attaches thereto. In one embodiment, the accessory or accessories report how much power they are consuming the electronic device. Each accessory that consumes power from the battery of the electronic device informs this to the electronic device. The information can, for example, be sent with commands, AT, as will be described later. When the power consumption of the accessory changes, a new report to the electronic device can be issued. Also, the accessory can send the average value of power consumption at certain regular time intervals. The accessory can derive its power consumption information by verifying its operation parameters and knowing the corresponding current required for each operation. Referring now to FIGURE 1, an exemplary diagram of a mobile terminal 110 connected to an exemplary accessory 150 in accordance with the present invention is generally illustrated at 100. Although the mobile terminal 110 is illustrated as a portable mobile telephone, the present invention It should not be limited to it. The mobile terminal 110 includes an antenna 115, a speaker 120, a screen 125, a keyboard 130, and four ports 135 of connection / interface points) for example an external connector with one or more input pins. Two of the four connection points 135 are points 135c and 135d of power connection, and two of the connection points are communication connection points 135a and 135b. It should be understood that connection points 135 may have more or less than the four shown. Likewise, the number of communication and power connection points 135a, 135b and 135c and 135d and 135d may be more or less than the two shown. The accessory 150 can be, for example, an infrared adapter unit, a portable hands-free unit, a vibration notification mechanism, etc. The accessory 150 is also shown as having four connection points 155, two of which are for communication (155a, 155b) and the other two for power (155c, 155d). It should be understood that the accessory unit 150 may also have more or less than the four connection points 155, and may be distributed differently. In other words, the connection points 155 may also be used in different ways (eg, in addition to communication and power). In addition, the number of communication points 155a, 155b (or, for example, points 155c, 155d) of power may be more or less than the two shown, for example. The accessory 150 can communicate with the mobile terminal 110 on communication connection lines 195a, 195b. The accessory 150, in one embodiment, receives power from a battery (not shown in FIGURE 1) of the mobile terminal 110 on power connection lines 195c, 195d. Referring now to FIGURE 2, internal circuits are illustrated for an exemplary mobile terminal 110 in accordance with the present invention. The different exemplary circuits may be interconnected by means of one or more bus bars 205. The internal circuit includes a battery 210 which is connected to the power connection points 135c, 135d and 'to the other internal circuits. They also include an input / output unit 215 connected to communication connection points 135a, 135b. Also included is a transmitter / receiver (TRX) 220, a horn 120, a screen 125, a keyboard 130, a microphone 225, and perhaps several other circuits (generally represented at 230). The mobile terminal 110 also includes one or more processors 235 and one or more memories 240. Within the memory 240, according to one embodiment of the present invention, a battery life application part 245 is stored. The battery life application part 245 may be, for example, encoded in hardware, software, firmware, or any combination thereof. The internal circuit may also include a battery detector 250. The battery detector 250 includes an ability, among others, to determine a total remaining charge in the battery 210 and the power consumption of the battery 210 of the internal circuit of the mobile telephone 110. Referring now to FIGURE 3A, exemplary functional blocks of an exemplary mobile terminal in accordance with the present invention are illustrated. The functional blocks of FIGURE 3A include a power source 305 (e.g. battery 210 of FIGURE 2) connected to power connection points 135c, 135d and a communication unit 310 connected to connection points 135a, 135b Communication. They also include several collectors 315 of internal power that are connected to the power source 305 and consume the power thereof.

The battery detector 250 (of FIGURE 2 may correspond to a functional battery level determining block 320 as well as a functional power determining block 330 (internal) The battery level determiner 320 can determine the total charge remaining within the power source 305. The battery level determiner 320 may also include (or otherwise be associated with) a load determining functional block speed 325 that determines the speed at which the remaining charge at the source 305 of power is being consumed.Determinator 330 of internal power extraction can determine the power that is being extracted from the internal circuit by, for example, measuring the speed of current consumption (for example, in (milli) amps ) by the internal circuit (for example, jointly (measuring the current draw by a total set of internal circuit at the same time), fragmented (measure one or more internal circuits sequentially or in parallel and then add them), etc.). The functional blocks of the mobile terminal 110 may also include a unit 335 for calculating remaining battery life. The calculation unit 335 can be taken as part of the battery life application part 245, the memory 240 and the processors 235 (as shown in FIGURE 2). Alternatively, the calculation unit 335 may be, for example, a separate set of firmware together with a digital signal processor (DSP). Referring now to FIGURE 3B, exemplary functional blocks of an exemplary accessory in accordance with the present invention are illustrated. Exemplary functional blocks include accessory collectors 355, which draw power from the power source 305 of the mobile terminal 110 (e.g., by means of the power connection points 155c, 155d of the accessory 150, the lines 195c, 195d of power connection and the power connection points 135c, 135d of the mobile terminal 110). They also include a functional 360 block determining accessory power extraction. The accessory power withdrawing determiner 360 can determine the power that is being extracted from the power source 305 of the mobile terminal 10 by, for example, measuring the current consumption (for example, in (milli) amps). The exemplary accessory 150 may also include a communication unit 365. The communication unit 365 of the accessory 150 communicates (for example, via the communication connection points 155a, 155b of the accessory 150, the communication connection lines 195a, 195b (of FIGURE 1, and the connection points 135a, 135b) communication of the mobile terminal 110 to inform the mobile terminal 110 of the current power draw of the accessory 150 (for example, in current as measured in (milli) amps.) When the present invention is carried out as a whole with a mobile terminal as illustrated in FIGURES 1-3, the remaining timeout of the mobile terminal is very important information that must be provided to the user.As mentioned above, it is especially difficult to produce an accurate prediction because the power consumption varies all the time (for example, as a result of the distance between the mobile terminal and the base station), however, the remaining waiting time can be calculated e in many ways. The aforementioned technique making references to FIGURES 3A and 3B measures the power consumption of current and from that measurement, calculates the remaining waiting time. This has, however, a secondary effect: "power" is lost in the measurement circuits (for example, the power extraction determiner 330 (internal) and the power extraction determiner 360). An alternative technique is to calculate the power consumption knowing the current operation parameters (for example, transmitter power, lights on / off, etc.). In other words, the power consumption of current can be calculated from the operational parameters of the system. From this calculation, the power consumption of only the mobile terminal itself is obtained without the teachings of the present invention. However, this alternative may be extended to the accessory connected to the mobile terminal according to the present invention. Referring now to FIGURE 3C, exemplary functional blocks for another exemplary mobile terminal in accordance with the present invention are illustrated. In the mobile termination 110 (of FIGURE 3C) the power extraction determiner 330 (internal) (of FIGURE 3A) is replaced with a determiner 330 'of operational (internal) parameter. Referring now to FIGURE 3D, exemplary functional blocks of another exemplary accessory in accordance with the present invention are illustrated. In the attachment 150 (of FIGURE 3D) the power extraction determiner 360 (of FIGURE 3B) is replaced with a determinant 360 'of operational parameter. Referring now to FIGURE 3E, an exemplary memory element of the exemplary mobile terminal of FIGURE 3C according to the present invention, is generally illustrated at 370. The memory element 370, which is part of the mobile terminal 110 (of FIGURE 3C), can be, for example, a non-volatile random access memory that is only read, rewritable memory, etc. The memory element 370 links various operational parameters of the mobile terminal 110 with the associated current extraction. For example, a backlight that can only be associated with "x" mA. Referring now to FIGURE 3F, an exemplary accessory element of FIGURE 3D according to the present invention is illustrated generally at 375. The memory element 375 that is part of the accessory 150 (of FIGURE 3D), may be, for example, a non-volatile random access memory that is only read, rewritable memory, etc. The memory element 375 links various operational parameters of the accessory 150 with the current code and / or associated current extraction. For example, a given processing state for accessory 150 may be associated with the code "y" mA and / or "z". The current code may be provided to the mobile terminal 110 instead of the current draw if, for example, the memory element 370 includes an input that links the current code of the accessory 150 to a current draw. Referring now to FIGURE 4A, an exemplary sequence diagram of signals / information exchanged between a mobile terminal and an accessory according to one embodiment of the present invention is generally shown at 400. Accessory 150 may optionally begin. the exchange with a signal / information "AT * ECUR =?" (for example, command, request, etc.) 410 transmitted to the mobile terminal 110. Referring now to FIGURE 4B, an exemplary command structure for exchanging signals / information between the mobile terminal and the accessory of FIGURE 4A in accordance with the present invention is generally illustrated at 450. Specifically, a command structure 450 is illustrated. "Exemplary AT * ECUR" that may be used in accordance with the principles of the present invention. An exemplary command syntax is shown at 460. This command can be used to inform the mobile terminal of the current consumption of a connected device (for example an accessory). The reported current value can be used to adjust the load parameters of the mobile terminal or to determine a total current draw. When the external device is connected, for example, the AT command may initially be generated. It can also be sent, for example, if the externally connected device changes the current consumption. In addition, it can also be sent as an average value at regular intervals. One command communicates with the current consumption information while another command determines if the "AT * ECUR" command is supported, each command can cause either an "OK" or an "ERROR" response. An exemplary definition "<; mamp > Pararaeter "is displayed at 470. This" AT * ECUR "command can be used to inform the mobile terminal of the current consumption for a device connected as a whole number, by dividing the whole number informed by" 10"the consumption of the device is provided. current in miliamps, in this exemplary embodiment An example of an "AT * ECUR" command exchange communicating to 12 mA of the connected device (eg, accessory 150) to the mobile terminal 110 is shown at 480. It should be noted that the constant "10" can be any number, and that it depends, for example, on the current physical limitations and the needs of a given device or system, Continuing now with FIGURE 4A, the mobile terminal 110, if configured in accordance with the present invention, it can respond with an affirmative signal / information 420"OK." If the mobile terminal 110 is not configured or does not understand the request, the mobile terminal 110 can respond with an indication "ERROR". however, the mobile terminal 110 responds with "OK", the accessory 150 then transmits a signal / information 430"AT * ECUR = < mamp > "to mobile terminal 110. The variable" < mamp > "may correspond, in one embodiment, the current consumption (for example, in amperage.) The mobile terminal 110 responds with a signal / information 440" OK "to the accessory 150 if the current consumption was received and understood successfully. If the mobile terminal 110 does not understand a communication of the accessory 150, the mobile terminal 110 may transmit an indication "ERROR." The signal / information 430 may be transmitted when, for example, the accessory 150 is initially connected to the mobile terminal 110. , the information / signal 430 can be transmitted at any time that the power consumption of the accessory 150 changes, at regular intervals, in the form of an average value, etc. In another embodiment, the signal / information 430 can be transmitted to the terminal 110 of the accessory 150 when the mobile terminal 110 requests said information / current consumption signal In another embodiment, the accessory 150 may (for example, as per a request terior of the mobile application 110, automatically, etc.) transmit the information / signal 430 of current consumption at periodic intervals (eg programmed, etc.). Referring now to FIGURE 5, an exemplary method in the form of a flow chart for accurately calculating the remaining life of a battery according to one embodiment of the present invention is generally illustrated at 500. An accessory is connected to a electronic device (block 510). In response, in this example, the accessory responds by transmitting a current consumption of the accessory to the electronic device (block 520). It should be noted that in block 520 the accessory can transmit any indicator related to energy. For example, instead of (or in addition to) current consumption, the accessory can transmit any consumption information related to general power, a set of operating parameters (e.g., in the form of code, etc.) of which the electronic device (e.g., the mobile terminal 110) can calculate an energy consumption (e.g., because the mobile terminal 110 stores information related to a parameter of particular operation with a particular energy consumption). In such alternative embodiments, the electronic device can determine the current consumption of the indicators related to received energy. The electronic device determines an internal current consumption (for example, by measuring a current draw, knowing the current draw of the active operational parameters, etc.) (block 530). The electronic device includes both the current consumption of the accessory and the internal current consumption in the calculations to obtain a total current consumption (block 540). The electronic device then calculates the remaining life of the battery (block 550). The remaining life of the battery is subsequently displayed by the electronic device (block 560). It should be noted that block 560, the electronic device (e.g., a mobile terminal) may provide notification to the user in a manner other than a visual display. For example, the electronic device may vibrate at a predetermined level of remaining battery time, may sound a characteristic audible noise (e.g., such as a predetermined tone or a predetermined number of beeps, etc.), etc. In this example, if the accessory changes the current consumption (and thus notifies the electronic device) (block, 570), the method of the flow diagram 500 can return to block 520. If, on the other hand, the accessory the current consumption does not change (in block 570), the flow chart method 500 can return to block 530. Referring now to FIGURE 6A, exemplary functional blocks of an exemplary accessory according to another embodiment of the present invention are generally illustrated at 600. In this embodiment, the accessory may also have a battery 605. Accessory 600 may not have the ability to directly communicate to a user the amount of time remaining from the power supply of battery 605. Consequently, in this mode, the accessory 600 transmits to a connected mobile terminal (not explicitly shown) or any general electronic device information related to the power supply remaining. The transmission can be sent from the points 155a, 155b communication connection to the mobile terminal. Especially in this embodiment, the communication connection points 155a, 155b can be carried out (in addition to mechanical, metallic, connection points, etc.) as an IR input / output port, a short-range radio frequency transmitter-receiver. (for example, a Bluetooth transceiver), etc. The fixture may also include a power extraction de- terminator 360 and / or an operational parameter determiner 360 '(eg, together with a memory element 375) to be able to determine the power consumption. In an alternative of this mode, the information related to the remaining power supply may correspond to the amount of time remaining in the life of the accessory battery 605 so that the mobile terminal can communicate (e.g., display) the amount of time remaining in the life of the 605 battery from the accessory to the user. In another alternative of this embodiment, the accessory 600 can transmit the current consumption and (optionally) the total remaining charge in the battery 605 to the mobile terminal. The mobile terminal may thereafter determine the remaining life of the battery 605 and communicate it to the user. Referring now to FIGURE 6B, an exemplary method in the form of a flow chart of the embodiment of FIGURE 6A in accordance with the present invention is generally illustrated at 650. The accessory receives a command to report power information (block 655). The command can receive from an electronic device, of a user directly being that the accessory reports the power information, of an integrated circuit internal to the accessory (for example, at regular intervals, when the current consumption changes, etc.), etc. The accessory provides power information to the electronic device (block 660). The power information may include remaining battery life, a total charge, together with a current consumption (eg, as measured, as determined from operational parameters, etc.), a list of operational parameters, etc. After any appropriate calculation, memory search, etc., as necessary, the electronic device indicates the remaining life of the battery to the user (block 665). The indication can be, for example, visual, audible, perceptible, etc. Although the preferred embodiments of the method, system and apparatus of the present invention have been illustrated in the accompanying drawings and described in the above detailed description, it should be understood that the present invention is not limited to the described embodiments, but is capable of several reconfigurations, modifications and substitutions without departing from the spirit and scope of the present invention as established and defined by the following claims.
