  • Patent number: 12587848
    Abstract: Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate sensor information to one or more display devices. Establishment of communication between devices can involve using a unique identifier associated with the sensor electronics module to authenticate communication. Times tracked at the sensor electronics module and the display module can be at different resolutions, and the different resolutions can be translated to facilitate communication. In addition, the frequency of establishing communication channels between the sensor electronics module and the display devices can vary depending upon whether reference calibration information is being updated.

  • Patent number: 12484294
    Abstract: A vertical fin-based field effect transistor (FinFET) device includes an array of FinFETs comprising a plurality of rows and columns of separated fins. Each of the separated fins has a length and a width measured laterally with respect to the length and includes a first fin tip disposed at a first end of the separated fin, a second fin tip disposed at a second end of the separated fin opposing the first end, a central region disposed between the first fin tip and the second fin tip and characterized by a first electrical conductivity, and a source contact electrically coupled to the central region. The first fin tip and the second fin tip are characterized by a second electrical conductivity less than the first electrical conductivity. The FinFET further includes a first gate region surrounding the first fin tip and a second gate region surrounding the second fin tip.

  • Patent number: 12475138
    Abstract: Systems and methods described herein may improve data migration between databases that store data under different schemas. Such systems and methods may be used to transform data from a first schema (e.g., tabular, such as in relational databases) to second schema (e.g., document-based, such as in some non-relational databases). In some embodiments, data transformation for database migration may be performed using at least one rule (e.g., specified by a user) specifying a logical arrangement under the second schema for transforming a grouping of source data under the first schema. For example, tables under a tabular schema may be transformed into new documents and/or fields within documents under a document-based schema in a manner specified by the transform rule(s). In some embodiments, transforming source data in this manner permits organizing the migrated data efficiently to reduce computing resources needed to migrate the data between databases and/or for future data access operations.

  • Publication number: 20250342139
    Abstract: Described herein are LLM-assisted techniques for data operation migration between a first schema and a second schema, which may take into account differences between a first dataset under the first schema and a second dataset under the second schema to which the first dataset has been or will be converted. In some embodiments, responsive to receiving a first data request targeting a subset of first data stored in a first database under a first schema, wherein second data is stored in a second database under a second schema and includes a migrated version of the first data, the first data request may be converted into a second data request targeting a subset of the second data that comprises a migrated version of the subset of the first data. Taking into account differences between the schemas may provide migrated data operations that are efficient to run on the destination schema.

  • Patent number: 12353616
    Abstract: Systems and methods for collecting visual attention information are described. The methods comprise the steps of displaying a browser window on a display (210); estimating a user's (220) gaze point within the display (210); transforming the geometry of the estimated gaze point and/or the geometry of the browser window to a common coordinate system; identifying an object (215) in the browser window that corresponds to the estimated gaze point; and storing the estimated gaze point and data corresponding to the identified object (215).

  • Publication number: 20250139610
    Abstract: One or more surface features (e.g., capacitive buttons, fingerprint sensor) may be exposed on a surface of a card (e.g., chi payment card). The card may store multiple applications/accounts of a user. The card receives a selection of one of the accounts by the user placing a finger on or pressing on a surface feature associated with the selected account. The card provides credentials associated with the selected account to a terminal. The multi-application card may disable credentials associated with the remaining accounts thereby appearing as a single-application card to the terminal during a transaction.

  • Patent number: 12224041
    Abstract: Disclosed herein are techniques for implementation of a Hemoglobin A (HBA) assay and an HBA genotyping decision tree matrix in clinical testing. Particularly, aspects are directed to obtaining raw data from the HBA assay performed on a plurality of samples, calculating a first set of probe ratios for each sample based on the raw data, identifying a number of reference samples to be combined as a synthetic reference sample based on the first set of probe ratios, calculating a second set of probe ratios for each sample of the plurality of samples based on the raw data and the synthetic reference sample, and determining, by the decision tree matrix, an HBA genotype for each sample based on the second set of probe ratios for each sample and copy number calling thresholds for sample probe/reference probe ratios associated with each probe of the plurality of probes.

  • Patent number: 11842269
    Abstract: Example implementations described herein can dynamically adapt to changing nature of sensor data traffic and through artificial intelligence (AI, strike a good tradeoff between reducing volume of sensed data, and retain enough data fidelity so that subsequent analytics applications perform well. The example implementations eliminate heuristic methods of setting sensing parameters (such as DAQ sampling rate, resolution etc.) and replaces them with an automated, AI driven edge solution core that can be readily ported on any Internet of Things (IoT) edge gateway that is connected to the DAQ.
