  • Patent number: 11931178
    Abstract: The present invention relates to a wearable device for healthcare and method for using the device. More specifically, the wearable device is worn on a finger for measuring the health data of the user, selected from one or more of heart rate, blood oxygen saturation, heart rate variability. Based on the measured data, the sleep quality can be monitored and recorded. Disorders such as obstructive sleep apnea (OSA), can be detected. The wearable device may include an optical sensor coupled with or embedded in a main body including a visible light emitter, an IR light emitter and a light detector being arranged along a longitudinal direction of the finger. During operation of the wearable device, the heart rate is monitored based on a detected light signal. When the heart rate is higher than an adaptive threshold, both heart rate and blood oxygen saturation are monitored.

  • Publication number: 20210012416
    Abstract: A method for using blockchain technology to ensure the authenticity of utility industry infrastructure assets includes packing the assets to form a digital asset package that meets certain conditions. The asset package, also referred to as an asset-backed security, may be exchanged based on the up-to-date condition of the asset package. The methods ensure the authenticity of transactions so that the data cannot be tampered with. The methods can open the door of financing from public offering markets to small and medium-sized enterprises and help these enterprises to use asset-backed securitization to solve their financing issues. The methods can also be used to create the assets for digitization and upload on the blockchain. Credit verification of assets may include various steps and the verification data may be stored in blocks and put on the blockchain. The methods can also support an ongoing flow of dynamic information about the asset.

  • Publication number: 20200342530
    Abstract: A method for combining a dynamic asset package with a pool of assets prevents problems and reduces risks with asset-backed securities. The dynamic package can support removing and replacing an individual asset so that problematic assets can be replaced, thus maintaining asset package value transparently. Updates to the asset package can be recorded on the blockchain to prevent tampering. With an appropriately maintained extensive pool of assets, the methods can provide good candidates available to replace bad assets in various packages, allowing the reliable maintenance of packages at the expected quality. The pool of assets and the asset packages can be managed such that the expected flow of new assets will be sufficient to maintain the quality of the defined packages. The resulting dynamic asset package will be of good quality and the risks will be much lower than that found in conventional static asset packages.

  • Publication number: 20200342529
    Abstract: A method for creating assets for digitization and upload on the blockchain include a verification of assets that can include various steps, including public record verification and verification via other platforms, utilizing multiple cross-checks as available. This verification data may be stored in blocks and put on the blockchain. Through these methods, strong and safe digitized assets can be provided with real, highly transparent and authoritative public trusted data that cannot be tampered with. The methods can be expected to increase the current three percent of assets that are suitable for securitization via asset-backed securitization to upwards of thirty percent. The methods show, with trust, that the digital asset is a real and true asset before it is placed on the blockchain. The methods can also support an ongoing flow of dynamic information about the asset to much better reflect its current value.
