Abstract: A device implementing a system for mitigating noise includes at least one processor configured to receive a first audio signal corresponding to a first microphone, and determine whether wind noise is present based at least in part on the first audio signal. The processor is configured to select, based on the determining, a second audio signal from between second and third microphones.

The third microphone is disposed at another location that experiences less wind noise. The processor is configured to determine voice and noise reference values based on the first and the selected second audio signals, and perform noise suppression with respect to at least one of the first or the selected second audio signal, based on the voice or the noise reference value.

Abstract: Techniques are disclosed for detecting obstruction of a device's antenna(s) and then changing an operation of the device. A transmission time at which an antenna of an electronic device transmitted a signal can be identified. A response signal can be detected that was received at a receiver of the electronic device subsequent to the transmission time. Based on the response signal and on the transmission time, one or more response-signal characteristics can be determined. Based on the one or more response-signal characteristics, it can be determined that the antenna or that another antenna of the electronic device is at least partly blocked from emitting or receiving signals. In response to determining that the antenna is at least partly blocked, a changed type of operation can be identified, and the changed type of operation can be performed.

The cellular capable secondary wireless device pairs with the primary wireless device, which provides a configurable option to allow mobile terminated connections and/or messages to be received at the cellular capable secondary wireless device for multiple SIMs when the cellular capable secondary wireless device is not within proximity of the primary wireless device and is being worn. The primary wireless device indicates conditional forwarding to a second wireless network associated with a second SIM and adjusts notification alerts to reduce time for forwarding when the cellular capable secondary wireless device is separated from the primary wireless device and in use.

The acknowledgement selection affordance displays a plurality of acknowledgement options.

Abstract: A new approach is proposed that contemplates systems and methods to ascribe or transfer metadata from one search-related entity to another, where each entity can be one of subject or source, citation, and object or target. First, one or more complete or incomplete attributes associated with one or more of entities across source, citation and target are identified with a high degree of probable accuracy, wherein such metadata or attributes include but are not limited to, time, language, and location of the entities. The identified attributes are then ascribed or transferred from one entity where the metadata is available to other search entities. Finally, the transferred attributes can be utilized to facilitate the selection and ranking of the cited targets for the search result.

Abstract: Described herein is a channel state information (CSI) calculation method for non-coherent joint transmission by using a dependency between CSI reported for each CSI. In one embodiment, configuration of CSI reporting is such that CSI calculated for one CSI process (denoted as the reference CSI process) can be used for interference calculation for another CSI process (denoted as the dependent CSI process).

Abstract: An adaptive approach to image bracket determination and a more memory-efficient approach to image fusion, which are designed to generate low noise and high dynamic range (HDR) images in a wide variety of capturing conditions, are described. An incoming preview image stream may be obtained from an image capture device. When a capture request is received, an analysis may be performed on an image from the preview image stream that has a predetermined temporal relationship to the image capture request. Based on the analysis, a set of images (and their respective capture parameters, e.g., exposure time) may be determined for the image capture device to capture. As the determined set of images are captured, they may be registered and fused in a memory-efficient manner that, e.g., places an upper limit on the overall memory footprint of the registration and fusion operations—regardless of how many images are captured in total.

Abstract: A multi-touch capacitive touch sensor panel can be created using a substrate with column and row traces formed on either side of the substrate. To shield the column (sense) traces from the effects of capacitive coupling from a modulated Vcom layer in an adjacent liquid crystal display (LCD) or any source of capacitive coupling, the row traces can be widened to shield the column traces, and the row traces can be placed closer to the LCD. In particular, the rows can be widened so that there is spacing of about 30 microns between adjacent row traces. In this manner, the row traces can serve the dual functions of driving the touch sensor panel, and also the function of shielding the more sensitive column (sense) traces from the effects of capacitive coupling.

Abstract: When a device is successfully unlock using a facial recognition authentication process, feature vectors generated from images obtained during the facial recognition authentication process may be stored as temporary templates on the device. After a period of time, one of the temporary templates may be selected to be used as a “virtual” template for the device. For example, a median temporary template in the temporary templates may be selected as the virtual template. The performance of the virtual template may then be assessed over time and compared to the performance of templates generated from an enrollment process to determine if and how the virtual template is implemented on the device.

The processing unit may be operable to determine the information by transmitting optical energy through a first set of the micro-perforations into a body part of the user, receiving a reflected portion of the optical energy from the body part of the user through a second set of the micro-perforations, and analyzing the reflected portion of the optical energy.

Abstract: An audio system and a method of using the audio system to generate a head-related transfer function (HRTF) map, are described. The audio system can determine one or more HRTF and corresponding HRTF locations along an azimuthal path of an azimuth extending around a head of a user. The HRTFs or HRTF locations can be measured, and other HRTFs or HRTF locations can be interpolated or extrapolated. The HRTF map can include the HRTFs assigned to HRTF locations along the azimuth. HRTFs from the HRTF map are used to render spatial audio to the user. Other aspects are also described and claimed.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for mitigating HTTP transaction errors for a data connection. The wireless device may establish a data connection over a first network interface of the wireless device at an HTTP layer of the wireless device. A transport connection may support the data connections and may support multiple HTTP transactions. An advisory signal may be received at the HTTP layer and, responsive to the advisory signal including first information, the HTTP layer may determine that at least a portion of the HTTP transactions can be (safely) retried. The HTTP layer may terminate, without notifying the application layer, the portion of HTTP transactions and may initiate, via a second transport connection established over a second network interface, retries of the first portion of HTTP transactions.

Abstract: Devices, methods, and computer-readable media describing an adaptive approach to reference image selection are disclosed herein, e.g., to generate fused images with reduced motion distortion. More particularly, an incoming image stream may be obtained from an image capture device, which image stream may comprise a variety of different image captures, e.g., including “image frame pairs” (IFPs) that are captured consecutively, wherein the images in a given IFP are captured with differing exposure settings. When a capture request is received at the image capture device, the image capture device may select two or more images from the incoming image stream for fusion, e.g., including at least one IFP. In some embodiments, one of the images from the at least one IFP will be designated as the reference image for a fusion operation, e.g., based on a robust motion detection analysis process performed on the images of the at least one IFP.
