Abstract: In some implementations, a user equipment (UE) may determine an angular motion using at least one gyroscope. The UE may adjust at least one measurement from at least one sensor that is associated with the UE and used to measure relative position, based at least in part on the angular motion. Additionally, in some implementations, the UE may determine at least one distance between the at least one sensor and an estimated grip associated with the UE, and determine at least one translation associated with the at least one sensor based at least in part on the angular motion and the at least one distance. Accordingly, the UE may adjust the at least one measurement by offsetting the at least one measurement based at least in part on the at least one translation.

Abstract: Techniques described herein can address these and other issues by synchronizing the positioning of an adjustable lens in a camera assembly with the capture of an image frame by the image sensor and optimizing the position of the adjustable lens to reduce the amount of blur caused by translation of the camera assembly along a direction along the optical axis over the course of a frame. More specifically, techniques provide for moving the lens to a plurality of optimized positions, relative to the image sensor, over the course of a frame, to reduce motion blur in an image due to translation of the camera assembly in a direction of along the optical axis during the frame. Some embodiments may provide for “tight” synchronization in cases where the plurality of optimized positions are based on a time-dependent function that takes into account when each row of the image sensor is being exposed over the course of the frame.

Abstract: In some implementations, a mobile device may perform a plurality of signal strength measurements of a radio frequency (RF) signal transmitted by a satellite, wherein performing the plurality of signal strength measurements occurs over a period of time during which the mobile device is subject to a movement. The mobile device may determine, for each signal strength measurement of the plurality of signal strength measurements, a respective orientation of the mobile device corresponding to when the respective signal strength measurement was performed. The mobile device may determine a target orientation for the satellite-based communications based at least in part on a value of a particular signal strength measurement of the plurality of signal strength measurements and the respective orientation of the mobile device corresponding to the particular signal strength measurement. The mobile device may provide guidance for rotating the mobile device to the target orientation.

Abstract: Step detection accuracy in mobile devices is increased by determining whether swinging is taking place. According to the invention, swinging can be detected using threshold detection, Eigen analysis, hybrid frequency analysis, and/or gyroscope-based analysis, for example. The determination that swinging is (or may be) occurring can impact how the mobile device reports detected steps for step detection. A count of missteps and/or a level of certainty, based on swing detection, can be provided with a step count.

Abstract: This disclosure provides devices, computer programs and methods for determining a motion direction. In one aspect, a mobile device includes sensors for measuring acceleration data. The mobile device also includes a processor and a memory that implement a motion direction estimation module configured to determine a primary axis of motion. The motion direction estimation module also determines a motion direction along the primary axis. The determination includes fitting the acceleration data, or data derived therefrom, to a bimodal distribution. A first peak of the bimodal distribution corresponds to a first motion direction along the primary axis, and a second peak corresponds to a second motion direction opposite the first. The motion direction estimation module is configured to estimate the motion direction based on the bimodal distribution. In some implementations, the motion direction estimation module selects the motion direction corresponding to the higher of the peaks as the estimated motion direction.

Abstract: An apparatus and method for providing a direction based on an angle of a reference wall is provided. A mobile device uses an angle of a horizontal feature from an image to calibrate a sensor and future sensor measurements. The angle of the horizontal feature is determined by image processing and this angle is mapped to one of four assumed parallel or perpendicular angles of an interior of a building. A sensor correction value is determined from a difference between the sensor-determined angle and the image-processing determined angle. The image processing determined angle is assumed to be very accurate and without accumulated errors or offsets that the sensor measurements may contain.

Abstract: In mobility scenarios, a user equipment (UE) may enter an airplane mod in which the UE has limited or no connectivity to a network. Cell selection latency after terminating the airplane mode may result in a delay in providing network or communication services. Some aspects described herein enable a reduction in latency associated with cell selection after operation in a mobility scenario. For example, a UE may determine that the UE is operating in a mobility scenario, and perform a receive-only cell selection procedure. Additionally, or alternatively, the UE may predict a destination associated with the mobility scenario and may identify a band list for performing a cell selection procedure. In this way, when the UE exits the mobility scenario, the UE reduces a time to successfully complete cell selection.
