Abstract: Compound structures and methods for forming the same are described. The compound structures can be used to form an enclosure. The enclosure may be formed from metal, such as aluminum, and further include one or more non-metal regions that allow for transmission and receipt of electromagnetic waves, such as radio frequency waves. The non-metal region can include a first section, a second section, and an optional cosmetic section. The first section can be firmly molded onto a metal section of the enclosure by small pores formed within the metal section. The second section can engage with interlock features of the first section. The optional cosmetic section can cover the first section and the second section such that the first section and the second section are not visible from an exterior of the enclosure.

Abstract: Disclosed herein are techniques for pre-processing a multiple-channel image for compression. The multiple-channel image can be composed of a collection of pixels that are represented using a floating-point format (e.g., half-precision/16-bit) for display on devices optimized for wide-gamut color space. The techniques can include a first step of quantizing the pixels into a fixed range of values, and applying invertible color-space transformations to the sub-pixels of each pixel—which can include red, green, blue, and alpha sub-pixels—to produce transformed sub-pixels including luma and chroma values. Next, the luma sub-pixels are placed into a luma data stream, the first and second chroma values are placed into a chroma data stream, and the alpha sub-pixels are placed into an alpha data stream. Predictive functions are then applied to the luma and chroma data streams. Finally, the various streams are separated into buffers and compressed to produce a multiple-channel image.

Abstract: Systems and methods are described for rate-limiting a message-sending client interacting with a message service based on dynamically calculated risk assessments of the probability that the client is, or is not, a sender of a spam messages. The message service sends a proof of work problem to a sending client device with a difficulty level that is related to a risk assessment that the client is a sender of spam messages. The message system limits the rate at which a known or suspected spammer can send messages by giving the known or suspected spammer client harder proof of work problems to solve, while minimizing the burden on normal users of the message system by given them easier proof of work problems to solve that can typically be solved by the client within the time that it takes to type a message.

Abstract: Companion and accessory devices can be wirelessly leashed together in a manner that enables the devices to estimate their proximities to each other. One device can periodically attempt to detect a signal from the other device. For each attempt, the attempting device can store an indication of whether the signal was detected. If a number of times that the signal was undetected exceeds a threshold, then the attempting device can perform specified operations, such as alerting a user that the wireless leash was broken. As another example, one device can detect that a strength of a signal from the other device exceeds a threshold. In response, the detecting device can measure signal strengths more frequently. If the measuring device then detects that the signal strength exceeds another threshold, then the measuring device can cause specified operations to be performed, such as data synchronization between the devices or unlocking a device.

Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of display pixels that provide image light to a user. The array of display pixels may form an active display structure with a rectangular shape. The rectangular active display structure may be surrounded by an inactive border region. Optical structures such as a sheet of glass or another optical member may have portions that are configured to bend light from the display pixels along the periphery of the active display structure. The optical member may have an area that is larger than the area of the active display structure, so that the presence of the optical member may serve to enlarge the apparent size of the display. Solidified liquid polymer may be used to support the optical structures and may be interposed between the optical structures and the active display structures.

Abstract: Systems and methods are disclosed for scheduling threads on a processor that has at least two different core types, such as an asymmetric multiprocessing system. Each core type can run at a plurality of selectable voltage and frequency scaling (DVFS) states. Threads from a plurality of processes can be grouped into thread groups. Execution metrics are accumulated for threads of a thread group and fed into a plurality of tunable controllers for the thread group. A closed loop performance control (CLPC) system determines a control effort for the thread group and maps the control effort to a recommended core type and DVFS state. A closed loop thermal and power management system can limit the control effort determined by the CLPC for a thread group, and limit the power, core type, and DVFS states for the system. Deferred interrupts can be used to increase performance.

Abstract: The present disclosure describes techniques for removing unnecessary processing stages from a graphics processing pipeline based on the format of data passed between the stages. Starting with a stage at a middle point in a pipeline, formats of data that are input to and output from the middle stage may be compared to each other. If the formats match, the middle stage may be removed from the pipeline. Thereafter, the format of data input to a pair of middle stages of the pipeline and output from the pipeline may be compared and, if they match, the middle pair may be deleted. This process may repeat until a middle pair is found where no match occurs between the input and output format. The remaining stages of the pipeline may be retained. In cases where a pipeline is not symmetrical, the formats of data at each node may be compared to each other.

Abstract: Systems and methods for modifying an appearance of a control based on detected changes in underlying content are disclosed. An example method includes: displaying a user interface on the display, the user interface including first content that is displayed at a respective region of the display using a first content-display value for a content-display property. The method also includes: displaying a control overlaying the first content, and the control having an appearance determined based on the first content-display value. The method additionally includes: detecting a change at the respective region that causes second content to be displayed at the respective region using a second content-display value for the content-display property. In response to detecting the change, the method includes: determining an updated appearance for the control based on the second content-display value for the content-display property; and displaying the control with the updated appearance overlaying the second content.

Abstract: Thermal compensation can be applied to force measurements of a force-sensitive button. A temperature differential between an object and the force-sensitive button can result in changes in the reconstructed force by the force sensor due to thermal effects rather than actual user force, which in turn can result in degraded performance of the force sensor (e.g., false positive or inconsistent activation force). In some examples, a force-sensitive button can include a force sensor configured to measure an amount of force applied to the force-sensitive button, and a temperature sensor configured to measure a temperature associated with the force sensor. The measured temperature can be used to compensate the amount of force measured by the force sensor based on the temperature associated with the force sensor. In some examples, the thermal compensation can be applied when an object is detected contacting the force-sensitive button (i.e., when rapid temperature differentials can occur).

Abstract: An encoder system may include an analyzer that analyzes a current image area in an input video to select a transform. A selectable residue transformer, controlled by the analyzer, may perform the selectable transform on a residue image generated from the current image area and a predicted current image area, to generate a transformed residue image. An encoder may encode the transformed residue image to generate output data. The analyzer controls the encoder to encode information to identify the selectable transform and to indicate that the selectable transform for the current image area is different from a transform of a previous image area of the input video. A decoder system may include components appropriate for decoding the output data from the encoder system.

Abstract: Techniques are disclosed for state-based location monitoring and determining a location of a mobile device. An application processor identifies a desired movement state. The application processor notifies a coprocessor of the desired state and enters a low power mode. The coprocessor monitors movement data to determine whether the desired state has occurred. In the event the desired state has occurred, the coprocessor will notify the application processor. The application processor can then determine whether it should switch to a high power mode.

Abstract: Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.
