  • Publication number: 20220382376
    Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

  • Publication number: 20220334544
    Abstract: The present embodiments relate to detecting instances of individuals being in peril within an independent or assisted living environment. According to certain aspects, with an individual's permission or affirmative consent, a hardware controller (such as a smart or interconnected home controller, or even a mobile device) may receive and analyze sensor data detected within the independent or assisted living environment to determine whether an individual may be in peril. In this circumstance, the hardware controller may generate a notification that indicates the situation and may communicate the notification to a proper individual, such as a family member or care giver, who may be in a position to mitigate or alleviate any risks posed by the situation. The foregoing functionality also may be used by an insurance provider to generate, update, or adjust insurance policies, premiums, rates, or discounts, and/or make recommendations to an insured individual.

  • Publication number: 20220327229
    Abstract: Embodiments of systems and methods for implementing data sovereignty safeguards in a distributed services network architecture are disclosed. Embodiments of a distributed services system may have a number of distributed nodes that each implements a set of services. When a user requests a service at a particular node of a distributed services system, the node is configured to determine if that node is not (or is) data sovereign for a region associated with the user. If the node is not data sovereign for the user's region, the user may be directed to a corresponding service at a node of the distributed service system that is data sovereign for the user's region.

  • Patent number: 11466325
    Abstract: Methods for determining the presence or absence of expansion of CGG repeat sequence in the FMR1 gene presence or absence of expansion of CCG repeat sequence in the FMR2 gene are provided. The methods are useful in identifying an individual with normal/intermediate, versus premutation or full mutation allele of FMR1 gene and FMR2 gene due to the expansion of CGG repeats and CCG repeats in the 5?-untranslated region respectively. The methods are also useful for screening newborns for fragile X syndrome or for screening women to determine heterozygosity status with full premutation of the CCG repeat tract. The methods are also useful in estimating the premutation and full mutation carrier frequency and estimating the prevalence of FXTAS AND FXPOI in a population. The methods are simple, rapid and require small amount of sample.

  • Publication number: 20220318118
    Abstract: Unexpected changes in application behavior are detected using time series telemetry in a manner that minimizes the upfront knowledge needed about the time series measurements themselves. A univariate analysis is performed on a set of operational metrics to identify anomalous signals indicative of potential anomalous events. A multivariate analysis is then performed to corroborate anomalous signals across groupings of metrics and to thereby determine that the anomalous signals correspond to an anomalous event. A boundary of the anomalous event is determined and the anomalous event is characterized based on a clustering of previously identified incidents. One or more participating entities are then determined for the anomalous event and a narrative description of the anomalous event is generated and presented to an end user. The narrative description identifies, among other things, the characterization of the anomalous event, a predicted cause of the anomalous event, and the participating entities.

  • Publication number: 20220316087
    Abstract: A ribbon is formed such that the ribbon floats on a melt using a cold initializer facing an exposed surface of the melt. The ribbon is single crystal silicon. The ribbon is pulled from the silicon melt at a low angle off the melt surface. The ribbon is formed at a same rate as the pulling. The ribbon is separated from the melt at a wall of the crucible where a stable meniscus forms. The ribbon has a thickness between a first surface and an opposite second surface from 50 ?m to 5 mm. The ribbon includes a first region extending a first depth from the first surface. The first region has a reduced oxygen concentration relative to a bulk of the ribbon.
