  • Patent number: 10958777
    Abstract: An electronic device includes one or more processors. When a first sensor delivers a first signal to the one or more processors indicating that the electronic device is in a stowed state, and a second sensor delivers a second signal to the one or more processors indicating that the electronic device is in a held state the one or more processors query the third sensor for a third signal indicating whether the electronic device is in the stowed state. The one or more processors perform a control operation when the third signal fails to indicate the electronic device is in the stowed state. The one or more processors omit performance of the control operation when the third signal indicates the electronic device is in the stowed state.

  • Patent number: 10904378
    Abstract: Techniques are described for implementing an immediate-mode camera for integration into portable personal electronic device (PPED) environments. Embodiments of the IMC can include an integrated digital camera that can be triggered directly by one or more user interface components, without involving waking up the application processor, waking up display components, waking up digital camera components, and/or starting up camera-related applications. For example, if a user's smart phone is locked, and the user desired to capture a photo, the user can interact with particular UI components in a particular manner, thereby directly triggering capture of image data by the IMC substantially without delay. Implementations of the IMC can involve a low-power, always-on digital camera that is directly controllable by one or more always-on user interface components. The IMC components can be in communication with an always-on region of the application processor via a fast hardware interface.
