  • Patent number: 11960739
    Abstract: The present disclosure is directed to a reference voltage calibration. An apparatus includes a memory and a memory controller including a calibration circuit configured to perform a reference voltage calibration to determine a reference voltage used to distinguish between logic values read from the memory. The reference voltage calibration comprises performing horizontal calibrations at different reference voltage values to determine a range of delay values applied to a data strobe signal at which valid data is read from the memory. The calibration includes determining scores corresponding to ones of the plurality of horizontal calibrations in which a score for a particular one of the plurality of horizontal calibrations is based on a corresponding range of delay values and a reference voltage margin. Thereafter, the calibration circuit selects a calibrated reference voltage based on the scores corresponding to ones of the plurality of horizontal calibrations.

  • Publication number: 20240079135
    Abstract: Techniques for providing remote patient assistance when network connectivity is unavailable include receiving, from a provider-side side remote patient monitoring (RPM) platform, a healthcare plan assigned to a patient; and while disconnected from the provider-side RPM platform: monitoring the patient; in response to the monitoring, determining whether to provide the medical information to the patient; and presenting the medical information to the patient, wherein the medical information is based on the healthcare plan and the monitoring.

  • Publication number: 20240062792
    Abstract: A memory subsystem and method for performing calibrations therein is disclosed. A memory subsystem includes a memory controller coupled to a memory by a plurality of signal paths. The memory controller is configured to perform an initial calibration to determine respective eye patterns corresponding to the ones of the plurality of signal paths. For a subsequent calibration, updated eye patterns are determined for a subset of the plurality of signal paths. Remaining ones of the plurality of signal paths (not included in the subset), are not active during the subsequent calibrations. Updated eye patterns for the remaining ones of the plurality of signal paths are determined based on information obtained during the initial calibration and information from signal paths in the subset designated proxies for the remaining ones of the plurality of signal paths.

  • Patent number: 11087700
    Abstract: A system for image enhancement on digital display device is disclosed. The system includes an image processing subsystem including a digital art metadata collection module to measure the ambient condition on a digital art piece using sensors. The digital art metadata collection module collects a set of metadata corresponding to the digital art piece by analysing the ambient condition. The image processing subsystem includes an image adjustment module to modify parameters on digital display device based on the set of metadata using one or more image processing techniques. The image adjustment module generates a target digital image representative of a printed image quality based on the modified parameters.
