Abstract: The invention provides devices and methods for non-invasive monitoring and measuring of intraocular pressure (IOP) of a subject. Embodiments include a lens that is adapted to fit on the subject's eye, a microstructure disposed in or on the lens, the microstructure having at least one feature that exhibits a change in shape and/or geometry and/or position on the lens in response to a change in curvature of the lens. When the curvature of the lens changes in response to a change in IOP, a corresponding change in shape and/or geometry and/or position of the feature may be used to determine the change in IOP. The change in the feature is detectable in digital images of the lens taken with a mobile electronic device such as a smartphone.

Abstract: The present disclosure presents a feedback active noise control system and strategy with online secondary-path modeling, and belongs to the technical field of active noise control. The linear prediction subsystem takes the residual noise as its input and separates the remaining sinusoidal noise from the broadband noise. The remaining sinusoidal noise is used effectively not only to update the controller but also to scale the auxiliary noise, while the broadband noise serves as a desired input of online secondary-path modeling subsystem. In this way, the coupling between the controller and the online secondary-path modeling subsystem is significantly mitigated, leading to both faster convergence and improved noise reduction performance. A practical scheme for refreshing the entire system is also developed to enhance its robustness against even abrupt changes with the secondary path or the primary noise.

Abstract: Described herein are embodiments related to defect detection in memory components of memory systems with time-varying bit error rate. A processing device determines that a bit error rate (BER) corresponding to a read operation to read a unit of data in a memory component satisfies a threshold criterion, determines a write-to-read (W2R) delay for the read operation, wherein the W2R delay comprises a difference between a time of the read operation and a write timestamp indicating when the unit of data was written to the memory component, and determines whether the W2R delay is within a W2R delay range corresponding to an initial read voltage level used by the read operation to read the unit of data. The processing device initiates a defect detection operation responsive to the W2R delay being within the W2R delay range, the defect detection operation to detect time-varying defects in the memory component.
