  • Patent number: 11893570
    Abstract: A system is described to authorize a transaction using blockchain technology. For example, a transaction authorization system comprises a point of sale (POS) device, a mobile device, and a payment blockchain. The POS device can initiate a transaction by scanning one or more items to be purchased and generating a code comprising a transaction identifier and a total cost of the one or more items. The mobile device can receive the code and can generate a token comprising the transaction identifier, total cost, a selected payment method identifier, and a value that can identify an account of a person associated with the mobile device. The token is sent to a payment blockchain to authorize the transaction.

  • Patent number: 11883824
    Abstract: Disclosure relates to a device and a method of using the device for conducting biological and chemical assays on a sample. The device includes two plates. The first plate includes at least a first and a second sample contact areas on its inner surface. Each sample contact area includes spacers having a bottom end fixed on the inner surface and a top end that is distal to the inner surface. The spacers in the first sample contact area differ in height from those in the second sample contact area. The first and second sample contact areas are disposed at different depths along the inner surface of the first plate, so that the top ends of the spacers are aligned on the same flat plane. The method includes depositing the sample onto the sample contact areas, compressing the sample into a thin layer, and analyzing the sample.

  • Publication number: 20240027430
    Abstract: The disclosure provides a method for identifying a bio-entity including a cell type and count in a sample. The method includes: providing a device comprising a first plate, a second plate, and a patterned structural element; depositing the sample between the first and second plates; reducing the spacing of the first and second plates so that the first and second plates are in a closed configuration to compress the sample into a layer; and imaging the sample to obtain an image; and measuring and analyzing the image against a database generated with a machine learning model to obtain the bio-entity of the sample. The sample can be a blood sample, and the method can be a white blood cell differential test conducted with a mobile phone.
