Description

BACKGROUND

[0001] BACKGROUND AND RELATED ART

[0002] Wireless electronic devices provide users with enhanced freedom while maintaining connectivity to personal and professional communications. Wireless accessory devices allow for more efficient interaction with communications and other electronic devices. However, even electronic devices and accessory devices intended for wireless use conventionally require wired charging of internal power sources. Wireless charging technology is becoming more common, but exhibits lower power transfer performance, lower charging performance, slower data transfer, and other shortcomings compared to wired charging and data transfer. SUMMARY

[0003] In some embodiments, a user places an accessory device near an electronic dock to wirelessly charge the accessory device, wirelessly transfer data to the accessory device, or both. The user does not use the accessory device while the accessory device is connected to or resting on a wireless charging dock. In some embodiments, the accessory device enters a docked mode upon receiving wireless transfer energy from the dock. In some embodiments, the docked mode reduces power consumption of electronic components of the accessory device while the accessory device is on the dock. In some embodiments, the docked mode disables one or more communication devices of the accessory device to reduce interference with other nearby electronic devices. In some embodiments, the docked mode disables one or more output functions of the accessory device to limit inadvertent input to the accessory device or associated electronic devices. In some embodiments, the docked mode enables one or more input components of the accessory device to enable input to the accessory device or associated electronic devices while the accessory device is docked.

[0004] In some embodiments, a method of docking an accessory device includes receiving, at the accessory device, first transfer energy for wireless charging from a dock, setting a timer upon receiving the first transfer energy, entering a docked mode, and exiting the docked mode upon expiration of the timer.

[0015] The present disclosure generally relates to devices, systems, and methods for docking an accessory device onto a wireless charger. In some embodiments, the wireless charger is part of a docking station integrated into another electronic device, such as a peripheral docking station on a laptop computer. In some embodiments, the wireless charger is a dedicated docking station for the accessory device, such as a charging cradle for a remote control.

[0016] In some embodiments, the methods, devices, and systems described herein improve the charging performance or operational reliability of an accessory device when the accessory device is placed on a docking station by causing the accessory device to enter a docking mode. In some embodiments, a user docks an accessory device on another electronic device to charge the accessory device or transfer data between the electronic device and the accessory device. In some embodiments, the docking station includes a transmitter that generates an electromagnetic field. The electromagnetic field of the docking station can magnetically couple the transmitter to a receiver of the accessory device to induce a current in the receiver of the accessory device. In some embodiments, the docking station includes a transmission source that generates light energy that transfers energy to a photovoltaic device in the accessory device. In some embodiments, the docking station includes a transmission source that generates acoustic energy that transfers energy to a receiver or membrane in the accessory device through vibrations (i.e., compressional waves). In some embodiments, the docking station includes a transmitter that generates a variable electric field to capacitively couple the docking station to the accessory device.

[0017] Figure 1 is a perspective view of an embodiment of an electronic device 100 with an accessory device 108 docked. Figure 1 The electronic device 100 illustrated in FIG. 1 is a laptop computer having a first portion 102 and a second portion 104 that are movable relative to each other, while the accessory device 108 is a stylus that is paired with the electronic device to provide input and inking functionality.

[0018] In some embodiments, the processor 106 of the electronic device 100 is located in the second portion 104 and is in data communication with the transmitter 110 located in the first portion 102. When the accessory device 108 is placed in proximity to the transmitter 110, the receiver 112 receives transmission energy from the transmitter 110, and the accessory device 108 enters a docking mode. In the illustrated embodiment, the bezel in the first portion 102 containing the transmitter 110 acts as a docking station for the accessory device 108. In some embodiments, the docking station includes a retention mechanism (such as a mechanical retention mechanism, a magnetic retention mechanism, or an adhesive retention mechanism) to retain the accessory device 108 in proximity to the docking station. In some embodiments, the docking station is oriented such that gravity retains the accessory device 108 in proximity to the docking station.

[0019] When the accessory device 108 is docked, one or more components or features of the accessory device 108 can not be used. In some embodiments, charging of the accessory device 108 via the dock when the accessory device 108 is docked is improved by disabling one or more components or features that consume power from the accessory device power source. For example, a computer mouse can be docked on a wireless charging pad to charge the mouse between use sessions. The computer mouse is unable to provide meaningful input to a computing device when docked, so a communication device (e.g., a Bluetooth communication device) can be disabled to reduce power consumption and allow charging from the dock to be more efficient. Further, for an optical mouse, the optical sensor circuitry can also be disabled to further reduce power consumption.

[0020] In some embodiments, the accessory device is a wearable device, such as a smart watch. In some embodiments, the wearable device has a relatively small display or no display and communicates data to another computing device to display data collected by the smart watch. In at least some embodiments, a wearable device, such as a pedometer, disables data communication components and / or sensor components to conserve power.

[0021] In some embodiments, the accessory device operates in a docked mode (e.g., a low power mode) when it is docked, regardless of whether it is currently charging. For example, an accessory device that is fully charged while in a dock can stop charging, but continue to operate in the docked mode to prevent unintended outputs and better maintain the charged state.

[0022] Figure 2 is a side view of another embodiment of an accessory device 208 resting on a dock 214. In some embodiments, the accessory device 208 has a housing 216, and the receiver 212 is placed at or near a surface of the housing 216. The receiver 212 is placed near the transmitter 210 of the dock 214 so that the transmission energy 218 is transmitted to the receiver 212.

[0023] In some embodiments, the transmission energy 218 is transmitted through one or more components of the accessory device 208 and / or the dock 214 on its way to the receiver 212. In some embodiments, the housing 216 of the accessory device 208 and / or the cover 220 of the dock 214 are at least partially transparent to the transmission energy 218. In the illustrated embodiment with a transmitter 210 that generates an electromagnetic field, the cover 220 is a non-magnetic material to allow the transmission energy 218 to pass through the cover 220 to the receiver 212.

[0024] In some embodiments, the transmission energy 218 is light energy, where the dock 214 includes a light energy source (e.g., a light emitting diode), the cover 220 is light transparent, and the accessory device 208 includes a photovoltaic panel to receive the transmission energy 218.

[0025] An accessory device can have one or more features or components that allow a user to provide user input to the accessory device and / or an electronic device in data communication with the accessory device. In some embodiments, input components of an accessory device are disabled to prevent inadvertent input from a user when the accessory device is docked.

[0026] In some embodiments, an accessory device is a stylus, such as described with respect to Figure 1 The tip of the stylus can detect contact and / or proximity of the tip to a surface to communicate inking user input to an electronic device. In some embodiments, the stylus detects display proximity and broadcasts a wireless signal into the screen. A touch display module in the display then determines the stylus tip position. In other examples, the stylus includes one or more buttons on the stylus that a user presses to provide user input. In some embodiments, one or more of the buttons are disabled when docked to prevent accidental activation.

[0027] In some embodiments, an accessory device is a computing mouse described herein. Buttons of the mouse can be disabled so that pressing the buttons does not register user input. A ball, optical sensor, laser sensor, or other movement detection mechanism of the computing mouse can be disabled so that movement of the computing mouse relative to a surface on which the computing mouse is placed is not registered as user input.

[0028] In some embodiments, an accessory device is a keyboard. Buttons of the keyboard can be disabled so that pressing the buttons does not register user input. A trackpad, thumbstick, or other directional input mechanism of the keyboard can be disabled so that contact with or force applied to the directional input mechanism is not registered as user input when the keyboard is in a docked mode. In some embodiments, the docked mode enables keystroke input to allow a user to input commands to the keyboard and associated electronic device while the keyboard is docked.

[0029] In some embodiments, an accessory device is a touch-sensitive device. A touch-sensitive surface can be disabled so that contact with the touch-sensitive surface does not register user input. A touchpad, touchscreen, other capacitive touch-sensitive surface, other resistive touch-sensitive surface, or other touch-sensitive input mechanism can be disabled so that contact with or force applied to the touch-sensitive surface is not registered as user input when the touch-sensitive device is in a docked mode.

[0030] In some embodiments, output components of an accessory device are disabled to conserve power and / or prevent unintended output when the accessory device is docked. Unintended output can be distracting to a user and / or convey incorrect information.

[0031] In some embodiments, the accessory device is an audio device, such as a wireless speaker, headphones, non-headphones, or other audio device capable of generating audio signals to communicate with a user. In these embodiments, the audio device speaker(s) can be disabled when the audio device is in a docked mode. Conversely, according to some embodiments, a wireless speaker can be allowed to operate at a higher power level when in a docked mode.

[0032] In some embodiments, an audio device that is docked with another electronic device can experience radio frequency (RF) signals or interference from the electronic device. For example, a speaker that is docked with an electronic device can be located near a wireless communication antenna of the electronic device. In some examples, a docking station of the electronic device can utilize RF signals to communicate with the docked speaker. The RF signals provided by the electronic device can interfere with the audio signals produced by the speaker. As such, the speaker can disable the speaker driver or other audio components of the speaker when docked.

[0033] In some embodiments, the electronic device is a computing device, including but not limited to a laptop computer, a hybrid computer, a foldable computer, a tablet computer, a smartphone, a wearable computing device, or other computing device. In some embodiments, the electronic device includes a docking station that includes a transmitter. The transmitter can send transmission energy from the docking station to an accessory device. When a transmission current is applied to the transmitter in the docking station, the transmitter generates an electromagnetic field that extends beyond an outer surface of the docking station. A receiver placed within the electromagnetic field proximate to the docking station experiences the electromagnetic field. The variable electromagnetic field induces a current in the receiver. In some embodiments, the transmitter produces an RF signal in a near field communication (NFC) frequency range. In some embodiments, the coil is configured to implement a wireless charging protocol, such as those defined by the NFC and Qi standards.

[0034] In some embodiments, the transmitter transfers energy from the transmitter to the receiver to wirelessly charge a power source of the accessory device. In some embodiments, the power source is a battery. In some embodiments, the power source is a capacitor. In some embodiments, the transmitter modulates the transmission energy from the transmitter to the receiver to communicate data from the docking station and / or the electronic device to the accessory device.

[0035] As used herein, an accessory device is considered to be “docked” when it receives sufficient transmission energy from a transmission coil to charge the accessory device. The electronic device can or can not include a mechanical docking station for the accessory device. For example, an accessory device can be considered to be docked when it is placed on a flat charging pad assembly or magnetically coupled to a surface of the electronic device.

[0036] Wireless transfer of charging power and / or data to an accessory device while docked can be improved by disabling one or more components and / or features of the accessory device. According to some embodiments, to adjust the performance of the accessory device, the accessory device determines when the accessory device is docked and undocked. Figure 3 is a flowchart illustrating a method (322) of docking an accessory device according to some embodiments. In some embodiments, a method of docking an accessory device includes receiving (324), at the accessory device, a first transfer energy for wireless charging from a docking station. In some embodiments, the first transfer energy is an electromagnetic field. In some embodiments, the first transfer energy is light energy. In some embodiments, the first transfer energy is acoustic energy that transfers energy to a receiver or membrane in the accessory device through vibrations (i.e., compressional waves). In some embodiments, the first transfer energy is a variable electric field to capacitively couple the docking station to the accessory device. In some embodiments, the accessory device determines whether the first transfer energy satisfies one or more criteria (e.g., has a sufficient magnitude for establishing charging) and determines that the accessory device is docked according to a determination that the first transfer energy satisfies the one or more criteria. In some embodiments, the accessory device modulates the first transfer energy to communicate with the electronic device. In some embodiments, the accessory device determines that it is docked according to receiving a response to the modulated first transfer energy from the electronic device.

[0037] In some embodiments, when the accessory device receives the first transfer energy for wireless charging from the docking station, the accessory device is determined to be docked, and the method includes setting (326) a timer upon receiving the first transfer energy and entering (328) a docked mode. The method includes the accessory device exiting (330) the docked mode upon expiration of the timer. In some embodiments, the docked mode is a sleep mode of the accessory device. In some embodiments, the accessory device is a smartphone, and the docked mode is an airplane mode that disables or modifies one or more communication components. In some embodiments, the docked mode is a low-power mode in which one or more components operate at a lower power consumption. In some embodiments, the docked mode is a high-power mode in which one or more components operate at full capacity.

[0038] In some embodiments, a timer is set to last for a first duration upon receiving the first transmitted energy. For example, the first duration may have an upper limit and a lower limit, or any value between any of the following: 10 milliseconds (ms), 50 ms, 100 ms, 150 ms, 200 ms, 250 ms, 300 ms, 400 ms, 500 ms, 750 ms, 1 second (s), 1.25 s, 1.5 s, 2.0 s. In some embodiments, the first duration of the timer is greater than 10 ms. In some embodiments, the first duration of the timer is less than 2.0 s. In some embodiments, the first duration of the timer is less than 1.0 s. In some embodiments, the first duration of the timer is between 10 ms and 2.0 s. In some embodiments, the first duration of the timer is between 50 ms and 1.0 s. In some embodiments, the first duration of the timer is between 100 ms and 500 ms. In some embodiments, the first duration of the timer is approximately 250 ms.

[0039] The accessory device remains in docking mode while the timer is running. Upon expiration of the timer, the accessory device exits docking mode. In some embodiments, the accessory device receives a second transmission of energy from the docking dock before the timer expires. After receiving the second transmission, the accessory device resets the timer.

[0040] Figure 4 This is a flowchart illustrating, according to some embodiments, a method (422) in which an accessory device resets a timer upon receiving second transmitted energy. In some embodiments, the method includes: at the accessory device, receiving (424) first transmitted energy for wireless charging from a docking station; setting (426) a timer upon receiving the first transmitted energy to enter (428) a docking mode; and exiting (430) the docking mode upon the timer expires, similar to the method described above. Figure 3 The method described (322). Figure 4 The method further includes, while in docking mode, receiving (432) a second transmission energy after setting a timer and before the timer expires, and resetting (434) the timer upon receiving the second transmission energy. In some embodiments, the method includes receiving a series of transmission energies and resetting the timer each time transmission energy is received to keep the accessory device in docking mode. When no transmission energy is detected for a duration equal to the timer duration, the timer expires without being reset, and the accessory device exits docking mode.

[0041] In some embodiments, the second transmission energy is the same as the first transmission energy. In some embodiments, the first transmission energy is a first transmission current applied to the transmitter for a first length of time. In some embodiments, the second transmission energy has the same magnitude and / or length as the first transmission energy. In some embodiments, the second transmission energy has a different magnitude than the first transmission energy. In some embodiments, the second transmission energy has a different length than the first transmission energy.

[0042] In some embodiments, the first transmission energy is an analog ping used by the transmitter and / or the docking station to detect the presence of a metallic object proximate to the transmitter, and the second transmission energy is a digital ping that includes modulation to provide data communication with a chargeable accessory device. In such embodiments, the accessory device receives the analog ping, enters a docking mode, and sets a timer to have a first duration. Upon receipt of the digital ping, the accessory device resets the timer and remains in the docking mode.

[0043] In some embodiments, the first transmission energy is a ping used by the transmitter and / or the docking station to detect the presence of a metallic object proximate to the transmitter or to confirm the identity of a metallic object proximate to the transmitter, and the second transmission energy is a charging energy used to charge a chargeable accessory device. In such embodiments, the accessory device receives the ping, enters a docking mode, and sets a timer to have a first duration. Upon receipt of the charging energy, the accessory device resets the timer and remains in the docking mode.

[0044] In some embodiments, resetting the timer includes resetting the timer to the first duration. In at least one example, the first duration of the timer is 250 ms. If the second transmission energy is received within 250 ms of starting the timer, the timer is reset to 250 ms. When the accessory device does not receive transmission energy from the docking station for 250 ms or more, the accessory device exits the docking mode.

[0045] In some embodiments, resetting the timer includes resetting the timer to a second duration that is different than the first duration. In some embodiments, the second duration is shorter than the first duration. In some examples, where the transmitter changes a transmission current (e.g., current in the transmitter) from the first transmission energy to the second transmission energy causing a delay between the transmission energies, the first duration is longer than the second duration. In some embodiments, each subsequent second transmission energy is spaced apart by a consistent time gap (e.g., period), and the second duration is different than the first duration to reflect the period of the second transmission energy. In some embodiments, the second duration is longer than the first duration. In at least one example, the first duration of the timer is 250 ms. If the second transmission energy is received within 250 ms of starting the timer, the timer is reset to 250 ms.

[0046] In some embodiments, the timer duration is twice the time gap or period of the transmission energy pulse. For example, in a series of pulses with 100 ms periods, the timer duration is set to 200 ms. RF interference or another transmission or reception issue can cause a failure to detect a transmission energy pulse. A timer duration that is at least twice the time gap or period of the transmission energy pulse allows the accessory device to remain in the docked mode without exiting the docked mode even if one transmission energy pulse is missed. In some embodiments, as long as the accessory device continues to receive transmission energy before the timer expires, the timer continues to reset and the accessory device remains in the docked mode.

[0047] In some embodiments, the docked mode of the accessory device alters the operation of the accessory device. For example, when a user uses a stylus to provide input to an electronic device, the stylus can have a variety of active features and / or components, such as inking on a display of the electronic device using the stylus. The docked mode alters the operation of the accessory device by disabling or altering the operational power of one or more components of the accessory device, such as disabling wireless signals from the stylus when the stylus is placed in proximity to the display.

[0048] Figures 5 to 7 FIG. 1 is a system diagram schematically illustrating different embodiments of an accessory device. In some embodiments, a docked mode alters the operation of the accessory device. In some embodiments, while in the docked mode, the accessory device disables one or more features or components of the accessory device that consume power, transmit data, receive input, or can interfere with a docking station or an electronic device.

[0049] Reference is now made to Figure 5 In some embodiments, the accessory device 508 includes one or more electrical components that are not used when the accessory device is docked. In some embodiments, the accessory device 508 includes a processor 536 in communication with the power source 538 and with an NFC receiver 540 via an NFC transceiver 541. The processor 536 is further in communication with a communication device 542. In some embodiments, disabling or reducing the power of an electrical component, such as the communication device 542, reduces the consumption of the power source 538 of the accessory device, allowing the power source 538 to charge faster when the accessory device 508 is docked and receiving power via the NFC receiver 540.

[0050] In some embodiments, the accessory device 508 includes a hardware storage device 544 in data communication with the processor 536. In some embodiments, the hardware storage device 544 includes instructions stored thereon that, when executed by the processor 536, cause the processor 536 to perform any of the methods described herein. In some embodiments, the hardware storage device 544 is a solid state hardware storage device. In some embodiments, the hardware storage device 544 is a platter-based storage device. In some embodiments, the hardware storage device 544 is an optical disk drive.

[0051] Referring now to Figure 6 In some embodiments, the accessory device 608 includes one or more input components 646 that can potentially cause unintentional user input to the accessory device 608. In some embodiments, the accessory device 608 includes a processor 636 in communication with the power source 638 and with the NFC receiver 640 via the NFC transceiver 641. The processor 636 is further in communication with the communication device 642 and the hardware storage device 644.

[0052] In some embodiments, the accessory device 608 is in data communication with an electronic device, and the accessory device 608 includes one or more input components 646 that can potentially cause unintentional user input to the electronic device. In some embodiments, disabling the input components 646 or reducing the power of the input components 646 reduces the likelihood of unintentional input to the accessory device 608 and / or the electronic device when the accessory device 608 is docked.

[0053] Referring now to Figure 7 In some embodiments, the accessory device 708 includes one or more output components (e.g., audio device 748; display 750) that can potentially cause interference with a docking station or an electronic device and / or output components that can potentially receive interference and unintentionally output signals to a user. In some embodiments, the accessory device 708 includes a processor 736 in communication with the power source 738 and with the NFC receiver 740 via the NFC transceiver 741. The processor 736 is further in communication with the communication device 742 and the hardware storage device 744. In some embodiments, the processor 736 disables the audio device 748 and / or the display 750 when in a docked mode. Disabling the output components limits the likelihood of unintended output and can reduce power consumption when docked and charging.

[0054] In some embodiments, disabling the output component(s) or reducing the power of the output component(s) reduces the likelihood of unintended output from the accessory device 708 and / or the electronic device when the accessory device 708 is docked.

[0055] In some embodiments, enabling an output component of the accessory device (such as illuminating an indicator 752) upon entering the docking mode allows the user to confirm when the accessory device is docked. In some embodiments, enabling an output component (such as illuminating an indicator 752) while charging in the docking mode allows the user to confirm when the accessory device is docked and charging. In some embodiments, the indicator is turned off when the accessory device remains in the docking mode upon completion of charging of the accessory device.

[0056] In some embodiments, features or components that are disabled or operating at reduced power in the accessory device while in the docking mode are enabled or operating at full power upon exiting the docking mode. In the example of a stylus docking and charging on a laptop computer, the communication device of the stylus is enabled when the timer expires and the stylus exits the docking mode, allowing data communication between the stylus and the laptop computer.

[0057] Industrial applicability

[0058] The present disclosure generally relates to systems and methods for docking an accessory device onto a wireless charger. In some embodiments, the accessory device is docked to another electronic device. The electronic device can be a dedicated docking station for the accessory device. In some examples, the electronic device is a stand for the accessory device that provides charging of the accessory device or other communication with the accessory device. In other examples, the electronic device has a docking station in or on it, and the electronic device has additional functionality.

[0059] In some embodiments, a user docks an accessory device on another electronic device to charge the accessory device or transfer data between the electronic device and the accessory device. In some embodiments, the docking station includes a transmitter that generates an electromagnetic field. The electromagnetic field of the docking station can magnetically couple the transmitter to a receiver of the accessory device to induce a current in the receiver of the accessory device. In some embodiments, the docking station includes a transmission source that generates light energy that transfers energy to a photovoltaic device in the accessory device. In some embodiments, the docking station includes a transmission source that generates acoustic energy that transfers energy to a receiver or membrane in the accessory device through vibrations (i.e., compressional waves). In some embodiments, the docking station includes a transmitter that generates a variable electric field to capacitively couple the docking station to the accessory device.

[0060] One or more components or features of the accessory device can not be used when the accessory device is docked. In some embodiments, charging of the accessory device while the accessory device is docked is improved by disabling one or more components or features that consume power from the power source of the accessory device. For example, a computer mouse can be docked on a wireless charging pad to charge the mouse between use sessions. The computer mouse is unable to provide meaningful input to a computing device while docked, so a communication device (e.g., a Bluetooth communication device) can be disabled to reduce power consumption and allow charging from the docking station to be more efficient.

[0061] In some embodiments, the accessory device is a wearable device, such as a smart watch. In some embodiments, the wearable device has a relatively small display or no display and communicates data to another computing device to display data collected by the smart watch. In at least some embodiments, a wearable device, such as a pedometer, disables a data communication device to conserve power.

[0062] In some embodiments, an input component of the accessory device is disabled to prevent inadvertent input from a user while the accessory device is docked. The accessory device can have one or more features or components that allow a user to provide user input to the accessory device and / or to an electronic device in data communication with the accessory device.

[0063] In some embodiments, the accessory device is a stylus. A tip of the stylus can detect contact and / or proximity of the tip to a surface to communicate inking user input to an electronic device. In other examples, the stylus includes one or more buttons on the stylus that a user presses to provide user input.

[0064] In some embodiments, the accessory device is a computing mouse as described herein. Buttons of the mouse can be disabled so that pressing the buttons does not register user input. A ball, optical sensor, laser sensor, or other movement detection mechanism of the computer mouse can be disabled so that movement of the computer mouse relative to a surface on which the computer mouse is placed is not registered as user input.

[0065] In some embodiments, the accessory device is a keyboard. Buttons of the keyboard can be disabled so that pressing the buttons does not register user input. A trackpad, thumbstick, or other directional input mechanism of the keyboard can be disabled so that contact with or force applied to the directional input mechanism is not registered as user input while the keyboard is in a docked mode. In some embodiments, the docked mode enables keystroke input to allow a user to input commands to the keyboard and an associated electronic device while the keyboard is docked.

[0066] In some embodiments, the accessory device is a touch-sensitive device. The touch- sensitive surface can be disabled so that contact with the touch-sensitive surface does not register user input. A touchpad, touch screen, other capacitive touch-sensitive surface, other resistive touch-sensitive surface, or other touch-sensitive input mechanism can be disabled so that contact with or force applied to the touch-sensitive surface is not registered as user input while the touch-sensitive device is in the docking mode.

[0067] In some embodiments, an output component of the accessory device is disabled to conserve power and / or prevent unintended output when the accessory device is docked. Unintended output can be distracting to a user or inadvertently convey false information. In some embodiments, the accessory device is an audio device, such as a wireless speaker, headphones, non-headphones, or other audio device capable of generating audio signals to communicate with a user.

[0068] In some embodiments, an audio device that is docked with another electronic device can experience RF signals or interference from the electronic device. For example, a speaker that is docked with an electronic device can be located near a wireless communication antenna of the electronic device. In some examples, a dock of the electronic device can utilize RF signals to communicate with the docked speaker. The RF signals provided by the electronic device can interfere with the audio signals produced by the speaker. As such, the speaker can disable the speaker driver or other audio components of the speaker when docked.

[0069] In some embodiments, the electronic device is a computing device, including but not limited to a laptop computer, a hybrid computer, a foldable computer, a tablet computer, a smartphone, a wearable computing device, or other computing device. In some embodiments, the electronic device includes a dock that includes a transmitter. The transmitter can send transmission energy from the dock to an accessory device. When a transmission current is applied to the transmitter in the dock, the transmitter generates an electromagnetic field that extends beyond an outer surface of the dock. A receiver placed within the electromagnetic field proximate to the dock experiences the electromagnetic field. The variable electromagnetic field induces a current in the receiver. In some embodiments, the transmitter produces an RF signal in a near field communication (NFC) frequency range.

[0070] In some embodiments, the transmitter transfers energy from the transmitter to the receiver to wirelessly charge a power source of the accessory device. In some embodiments, the power source is a battery. In some embodiments, the power source is a capacitor. In some embodiments, the transmitter modulates the transmission energy from the transmitter to the receiver to communicate data from the dock and / or the electronic device to the accessory device.

[0071] Wireless transmission of charging power and / or data to an accessory device while docked can be improved by disabling one or more components and / or features of the accessory device. To regulate the performance of the accessory device, the accessory device determines when the accessory device is docked and when the accessory device is undocked. In some embodiments, a method of docking an accessory device includes receiving, at the accessory device, a first transmitted energy for wireless charging from a docking station. In some embodiments, the first transmitted energy is an electromagnetic field. In some embodiments, the first transmitted energy is light energy. In some embodiments, the first transmitted energy is acoustic energy that transfers energy to a receiver or membrane in the accessory device through vibrations (i.e., compressional waves). In some embodiments, the first transmitted energy is a variable electric field to capacitively couple the docking station to the accessory device.

[0072] In some embodiments, when the accessory device receives the first transmitted energy for wireless charging from the docking station, the accessory device is determined to be docked, and the method includes setting a timer upon receiving the first transmitted energy and entering a docked mode. The accessory device remains in the docked mode until the timer expires. In some embodiments, the docked mode is a sleep mode of the accessory device. In some embodiments, the accessory device is a smartphone, and the docked mode is an airplane mode that disables or modifies one or more communication components. In some embodiments, the docked mode is a lower power mode in which one or more components operate at a lower power consumption. In some embodiments, the docked mode is a high power mode in which one or more components operate at full capacity.

[0073] In some embodiments, the timer is set to last for a first duration upon receiving the first transmitted energy. For example, the first duration ranges have upper and lower values that include any of 10 milliseconds (ms), 50 ms, 100 ms, 150 ms, 200 ms, 250 ms, 300 ms, 400 ms, 500 ms, 750 ms, 1 second (s), 1.25 s, 1.5 s, 2.0 s, or any value between these values. In some embodiments, the first duration of the timer is greater than 10 ms. In some embodiments, the first duration of the timer is less than 2.0 s. In some embodiments, the first duration of the timer is less than 1.0 s. In some embodiments, the first duration of the timer is between 10 ms and 2.0 s. In some embodiments, the first duration of the timer is between 50 ms and 1.0 s. In some embodiments, the first duration of the timer is between 100 ms and 500 ms. In some embodiments, the first duration of the timer is approximately 250 ms.

[0074] The accessory device remains in the docked mode while the timer is running. Upon expiration of the timer, the accessory device exits the docked mode. In some embodiments, the accessory device receives a second transfer of energy from the docking station prior to expiration of the timer. Upon receiving the second transfer, the accessory device resets the timer.

[0075] In some embodiments, the second transfer of energy is the same as the first transfer of energy. In some embodiments, the first transfer of energy is a first transfer current applied to the transmitter for a first length of time. In some embodiments, the second transfer of energy has the same magnitude and / or length as the first transfer of energy. In some embodiments, the second transfer of energy has a different magnitude than the first transfer of energy. In some embodiments, the second transfer of energy has a different length than the first transfer of energy.

[0076] In some embodiments, the first transfer of energy is an analog ping used by the transmitter and / or docking station to detect the presence of a metallic object proximate to the transmitter, and the second transfer of energy is a digital ping that includes modulation that provides data communication with a chargeable accessory device. In such embodiments, the accessory device receives the analog ping, enters the docked mode, and sets the timer to have a first duration. Upon receiving the digital ping, the accessory device resets the timer and remains in the docked mode.

[0077] In some embodiments, the first transfer of energy is a ping used by the transmitter and / or docking station to detect the presence of a metallic object proximate to the transmitter or to confirm the identity of a metallic object proximate to the transmitter, and the second transfer of energy is a charging energy used to charge a chargeable accessory device. In such embodiments, the accessory device receives the ping, enters the docked mode, and sets the timer to have a first duration. Upon receiving the charging energy, the accessory device resets the timer and remains in the docked mode.

[0078] In some embodiments, resetting the timer includes resetting the timer to the first duration. In at least one example, the first duration of the timer is 250 ms. If the second transfer of energy is received within 250 ms of starting the timer, the timer is reset to 250 ms. When the accessory device does not receive a transfer of energy from the docking station for 250 ms or more, the accessory device exits the docked mode.

[0079] In some embodiments, resetting the timer includes resetting the timer to a second duration that is different from the first duration. In some embodiments, the second duration is shorter than the first duration. In some examples, where the transmitter changes the transmission current (e.g., current in the transmitter) from the first transmission energy to the second transmission energy causing a delay between the transmission energies, the first duration is longer than the second duration. In some embodiments, each subsequent second transmission energy is separated by a consistent time gap (e.g., period), and the second duration is different from the first duration to reflect the period of the second transmission energy. In some embodiments, the second duration is longer than the first duration. In at least one example, the first duration of the timer is 250 ms. If a second transmission energy is received within the 250 ms of starting the timer, the timer is reset to 250 ms.

[0080] In some embodiments, the timer duration is twice the time gap or period of the transmission energy pulses. For example, in a series of pulses with a 100 ms period, the timer duration is set to 200 ms. RF interference or another transmission or reception issue can cause a failure to detect a transmission energy pulse. A timer duration that is at least twice the time gap or period of the transmission energy pulses allows the accessory device to remain in the docked mode without exiting the docked mode even if one transmission energy pulse is missed. In some embodiments, as long as the accessory device continues to receive transmission energy before the timer expires, the timer continues to reset and the accessory device remains in the docked mode.

[0081] In some embodiments, the docked mode of the accessory device changes the operation of the accessory device. For example, when a user uses a stylus to provide input to an electronic device, the stylus can have a variety of active features and / or components, such as inking on a display of the electronic device using the stylus. The docked mode changes the operation of the accessory device by disabling or changing the operational power of one or more components of the accessory device.

[0082] In some embodiments, the docked mode changes the operation of the accessory device. In some embodiments, while in the docked mode, the accessory device disables one or more features or components of the accessory device that consume power, transmit data, receive input, or can interfere with the docking station or electronic device.

[0083] In some embodiments, the accessory device includes one or more electrical components that are not used while the accessory device is docked. In some embodiments, disabling an electrical component, such as a data communication device, or reducing the power of an electrical component reduces the consumption of the power source of the accessory device, allowing the power source to charge faster while the accessory device is docked.

[0084] In some embodiments, the accessory device includes one or more input components that can potentially cause inadvertent user input to the accessory device. In some embodiments, the accessory device is in data communication with the electronic device, and the accessory device includes one or more input components that can potentially cause inadvertent user input to the electronic device. In some embodiments, disabling the input components or reducing the power of the input components reduces the likelihood of inadvertent input to the accessory device and / or the electronic device while the accessory device is docked.

[0085] In some embodiments, the accessory device includes one or more input components that can potentially cause inadvertent user input to the accessory device. In some embodiments, the accessory device is in data communication with the electronic device, and the accessory device includes one or more input components that can potentially cause inadvertent user input to the electronic device. In some embodiments, disabling the input components or reducing the power of the input components reduces the likelihood of inadvertent input to the accessory device and / or the electronic device while the accessory device is docked.

[0086] In some embodiments, a feature or component that is disabled or operating at reduced power in the accessory device while in the docked mode is enabled or operating at full power upon exiting the docked mode. In the example of a stylus docking and charging on a laptop computer, when the timer expires and the stylus exits the docked mode, the communication device of the stylus is enabled, allowing data communication between the stylus and the laptop computer.
