Abstract: Disclosed embodiments pertain to the measurement of heart rate in the presence of motion and noise. Spectral peaks in measurements by an optical sensor are compared with spectral peaks obtained from a motion sensor signal measurements, to obtain a fundamental frequency in the optical sensor signal, where the fundamental frequency is associated with a user's heart rate. A first heart rate may be estimated based on the fundamental frequency. A variety of quality metrics may be determined for the first heart rate estimate. A second estimated heart rate may be determined based by processing a frequency domain representation of the optical sensor signal based on a frequency domain representation of the motion sensor signal. One or more of the previously determined quality metrics may be dynamically adjusted based on a comparison of first and second estimated heart rates.

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: Disclosed are systems, devices, and methods for compensating for roll blur in an optical image stabilization (OIS) module. An OIS controller receives a selection for one or more areas of interest (AOI), each AOI associated with an image optimization point (IOP), and each IOP is associated with an X position (Xpos) and a Y position (Ypos). The OIS controller receives gyroscope data comprising X axis rotation data (Xgyro), Y axis rotation data (Ygyro) and Z axis rotation data (Zgyro). The OIS controller generates adjusted X axis rotation data (Xgyro_adj) and Y axis rotation data (Ygyro_adj), wherein Xgyro_adj and Ygyro_adj based on the Z axis rotation data and the one or more IOPs and adjusts lens shift gain on the basis of Xgyro_adj and Ygyro_adj and adjusts lens movement based at least in part on the lens shift gain.

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: A mobile station improves its position estimate using dead reckoning and wireless signal distance estimates. The mobile station calculates a first round trip time (RTT) based distance at a first mobile station position between the first mobile station position and an access point. The mobile station moves to a second position and calculates a dead reckoning transition distance between the first mobile station position and the second mobile station position. The mobile station calculates a wireless signal transition distance between the first mobile station position and the second mobile station position based on a second RTT-based distance calculated between the access point and the second mobile station position. The mobile station computes an uncertainty associated with the first RTT-based distance and/or the second RTT-based distance using the dead reckoning transition distance and the wireless signal transition distance. The mobile station can correct the first RTT-based distance or the second RTT-based distanced based on comparing the dead reckoning transition distance with the wireless signal transition distance.

Abstract: This disclosure provides devices, computer programs, and methods for estimating reliability metrics. In one aspect, a mobile device includes sensors for measuring acceleration data, a processor, and a memory storing instructions that implement a plurality of modules. The modules include a motion direction estimation module for estimating a motion direction based on the acceleration data. The modules also include a reliability metric computation module for estimating reliability metrics. For example, the reliability metric computation module can estimate a first reliability metric based on a process used to estimate the motion direction, a second reliability metric based on a measure of stability of the device, and a third reliability metric based on a measure of consistency in the estimated motion direction over a period. The reliability metric computation module calculates a composite reliability metric that indicates a measure of certainty in the estimated motion direction based on the estimated reliability metrics.

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.
