Abstract: A wearable electronic device includes a body, a housing component, a band operable to attach the body to a body part of a user, and a force sensor coupled to the housing component. The force sensor is operable to produce a force signal based on a force exerted between the body part of the user and the housing component. A processing unit of the wearable electronic device receives the force signal from the force sensor and determines the force exerted on the housing component based thereon. The processing unit may use that force to determine a tightness of the band, determine health information for the user, adjust determined force exerted on a cover glass, and/or to perform various other actions.

Abstract: An electronic device displays, on a touch-sensitive display, a user interface for an application. The electronic device, while displaying the user interface for the application, detects a touch gesture that includes movement of a contact on the touch-sensitive display at least partially over the user interface for the application. The electronic device, in response to detecting the touch gesture, in accordance with a determination that the touch gesture meets first system navigation criteria and video is playing in the application when the touch gesture is detected, concurrently displays a home screen user interface and a representation of the video that is playing in the application. The electronic device, in accordance with a determination that the touch gesture meets the first system navigation criteria and there is not video playing in the application when the touch gesture is detected, displays the home screen user interface without displaying representation of the video.

Abstract: Thermal conditions can be simulated for an electronic device. Application developers may want to test how applications perform under various thermal conditions on a device that includes thermal management. The application developers can use the tests to determine whether the application should take proactive measures to maintain application performance, and which proactive measures should be taken. For example, an application can reduce its use of resources to ensure that an application maintains a desired quality of user experience (and at a minimum remains responsive) under adverse thermal conditions. Creating adverse conditions can be difficult to replicate, costly to implement, and can potential cause damage to the electronic device being tested. In some examples, simulating thermal conditions can be used instead of placing the device in real-world adverse conditions to improve the testing process for developers.

Abstract: Systems and methods are disclosed for advising a user when an energy storage device in a computing system needs charging. State of charge data of the energy storage device can be measured and stored at regular intervals. The historic state of charge data can be queried over a plurality of intervals and a state of charge curve generated that is representative of a user's charging habits over time. The state of charge curve can be used to generate a rate of charge histogram and an acceleration of charge histogram.

A first device can determine when a second device typically charges and whether the energy storage device in the second device will have an amount of energy below the predetermined threshold amount before the next predicted charge time for the second device.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated by a backlight unit that includes an array of light-emitting diodes (LEDs). The backlight unit may determine the type of content in the image data. The backlight unit may decide to prioritize either mitigating halo or mitigating clipping based on the type of content. The determination of the type of content in the image data may be used to determine the brightness values for the LEDs in the LED array. If the content is determined to be a first type of content, at least one given LED in the LED array may have a different brightness value than if the content is determined to be a second, different type of content. Classifying content in the image data may be useful in optimizing visible artifacts such as visible halo and clipping.

Abstract: The subject technology provides a framework for learning neural scene representations directly from images, without three-dimensional (3D) supervision, by a machine-learning model. In the disclosed systems and methods, 3D structure can be imposed by ensuring that the learned representation transforms like a real 3D scene. For example, a loss function can be provided which enforces equivariance of the scene representation with respect to 3D rotations. Because naive tensor rotations may not be used to define models that are equivariant with respect to 3D rotations, a new operation called an invertible shear rotation is disclosed, which has the desired equivariance property. In some implementations, the model can be used to generate a 3D representation, such as mesh, of an object from an image of the object.

Abstract: Electronic devices are often equipped with a camera for capturing video content and/or a display for displaying video content. However, amateur users often capture video content without regard to composition, framing, or camera movement, resulting in video content that can be jarring or confusing to viewers. There is a need to automate the processing and presentation of video content in an aesthetically pleasing manner. The embodiments described herein provide a method of automatically cropping video content for presentation on a display.
