  • Patent number: 11269393
    Abstract: This application relates to techniques that adjust the sleep states of a computing device based on proximity detection and predicted user activity. Proximity detection procedures can be used to determine a proximity between the computing device and a remote computing device coupled to the user. Based on these proximity detection procedures, the computing device can either correspondingly increase or decrease the amount power supplied to the various components during either a low-power sleep state or a high-power sleep state. Additionally, historical user activity data gathered on the computing device can be used to predict when the user will likely use the computing device. Based on the gathered historical user activity, deep sleep signals and light sleep signals can be issued at a time when the computing device is placed within a sleep state which can cause it to enter either a low-power sleep state or a high-power sleep state.

  • Publication number: 20210391739
    Abstract: A method of controlling charging of an electronic device includes estimating a usage time value that corresponds to an anticipated future occurrence of usage of the electronic device; and estimating a resume time value that corresponds to a time for charging to commence to allow for completion of charging from a first predetermined state of charge value to a second predetermined state of charge value by the usage time value. The method also includes charging a battery of the electronic device using electrical power supplied by a charging device until a current state of charge of the battery reaches the first predetermined state of charge value, entering, by the electronic device, a deactivated mode after the current state of charge reaches the first predetermined state of charge value, and causing the electronic device to return to the activated mode according to the resume time value.

  • Patent number: 11089398
    Abstract: A method of controlling charging of a wireless headphone device includes estimating a usage time value that corresponds to an anticipated future occurrence of usage of the wireless headphone device and estimating a resume time value that corresponds to a time for charging to commence to allow for completion of charging from a first predetermined state of charge value to a second predetermined state of charge value by the usage time value. The method also includes determining that the wireless headphone device has been placed in a charging case. A battery of the wireless headphone device is charged to the first predetermined state of charge value and then enters a deactivated mode, wherein the charging case is configured to return the wireless headphone device to an activated mode according to the resume time value.

  • Patent number: 11055492
    Abstract: Embodiments described herein provide techniques to encode sequential data in a privacy preserving manner before the data is sent to a sequence learning server. The server can then determine aggregate trends within an overall set of users, without having any specific knowledge about the contributions of individual users. The server can be used to learn new words generated by user client devices in a crowdsourced manner while maintaining local differential privacy of client devices. The server can also learn other sequential data including typed, autocorrected, revised text sequences, sequences of application launches, sequences of purchases on an application store, or other sequences of activities that can be performed on an electronic device.

  • Publication number: 20210083514
    Abstract: An electronic device may have a power system. The power system may receive power such as wireless power or wired power and may use a portion of the received power to charge a battery. Power consumption by control circuitry in the device can be adjusted by deactivating or activating processor cores in the control circuitry and by selectively starting or stopping software activities. By selectively reducing power consumption by circuitry in the electronic device other than battery charging circuitry in the power system that is charging the battery, additional power may be made available to charge the battery and/or battery capacity can be extended. The electronic device may reduce non-battery-charging activities in the device in response to information gathered with sensors such as motion and temperature information, information from the power system, information on device location, information on software settings, and other information.

  • Patent number: 10948973
    Abstract: An electronic device may have a power system with a battery. The power system receives power such as wireless power or wired power and uses a portion of the received power to charge the battery as needed. Control circuitry in the portable electronic device is used to run background processes such as image processing tasks, data synchronization tasks, indexing, and other background processes. In some circumstances, such as when the battery is below a certain state of charge threshold, background processes may be stopped so that the battery is charged as fast as possible. Once above this initial state of charge threshold, background processes may be performed during charging as long as the temperature and state of charge of the battery do not exceed safety temperature and safety state of charge values. Performing background processes in these conditions ensures requisite background processing tasks are completed while preserving battery health.

  • Publication number: 20200380984
    Abstract: Embodiments described herein provide for a multi-device context store in which context attributes of multiple devices can be synchronized. A first device can transmit a predicate to a second device, where the predicate includes a condition associated with an attribute of a multi-device context store. Upon the occurrence of the condition at the second device, a notification and/or context update can be sent by the second device to the first device. The predicate can also include a code block to be executed upon the occurrence of the condition.

  • Publication number: 20190305597
    Abstract: A power system uses a power transmitting device to charge batteries in power receiving devices. Wireless power is transmitted using coils in the power transmitting device and coils in the power receiving devices. Usage history information such as power consumption, times and dates of device usage, battery charge state information, device location information, and other information is gathered using portable electronic devices in the system. Control circuitry in the power transmitting device or elsewhere in the system controls power transfer so that battery charging is performed in accordance with appropriate battery charging settings. Battery charging settings such as maximum charge level, charge rate, charging start and stop times, and other settings are adjusted based on usage history information from one or more devices and/or one or more users.
