Abstract: Generating a user timeline for an electronic device (ED) userData is collected that includes: location data; application data; and activity data. Occurrences of predetermined types of observed events are detected based on the collected data. For each detected occurrence a respective observed event record is stored that includes information about a time and type of the observed event. Planned event records, each including information about a time and type of a respective planned event, are stored for planned events that the user is scheduled to participate in, the planned event records. Events are predicted based on the observed event records and the planned event records. Information about observed, planned and predicted events are output on a timeline user interface based on observed event records, planned event records and predicted event records stored for the predicted events, respectively.

Abstract: A data stream transmission method includes: sending a first target signal; obtaining a first moment, where the first moment is obtained based on a time point at which a first receiving device on a second device receives the first target signal; obtaining a second moment, where the second moment is obtained based on a time point at which a second receiving device on the second device receives the first target signal, where the first receiving device and the second receiving device are located at different positions of the second device, and the second device is a head-mounted device; and when determining, based on the first moment and the second moment, that a data transmission condition is met, transmitting a target data stream to the second device.

Abstract: A method and an apparatus for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment.

Abstract: A device searching method includes: a first device obtains a relative location between a second device and the first device based on location information of the first device and the location information of the second device; if it is determined, based on the relative location, that the second device is not within a shooting range of the first device, the first device indicates to move the first device toward the second device until the second device is within the shooting range of the first device; and the first device highlights the area in which the second device is located in the shooting range of the first device.

Abstract: A system includes a first subsystem and a second subsystem that are used in a same chip. A security level of a first physical resource included in the first subsystem is higher than a security level of a second physical resource included in the second subsystem. The first subsystem includes an interrupt controller, and the interrupt controller is configured to manage an interrupt of a peripheral of the second subsystem. Embodiments of this application are for isolation between subsystems of different security levels in a chip.

Abstract: There is provided a method and apparatus for tracking a device. The tracked device may be a wearable device worn by a user participating in an athletic activity. An anchor device is positioned with respect to a playing area and receives signals from the tracked device. The anchor device estimates the position of the tracked device by measuring a distance and direction of the signal, and decodes the signal to obtain measurements taken by the tracked device. The position and the measurements are combined to produce tracking data for the device.

Abstract: Embodiments relate to audio stream and address processing methodologies, which is applicable to exemplary methods and devices including a first terminal device. The first terminal device establishes a connection to the vehicle, and switches a play device of audio streams in a first category and a second category from the first terminal device to the vehicle; and in a process in which the first terminal device and the vehicle are in a connected state, upon detecting that the first terminal device is moved from the inside of the vehicle to the outside of the vehicle, obtains a target category corresponding to the target audio stream being played by the vehicle. The target audio stream is generated by the first terminal device and sent to the vehicle. The vehicle continues to play the target audio stream if the target category is the first category.
