  • Patent number: 12197456
    Abstract: Disclosed herein are system, method, and device embodiments for a data bridge adapter in a data integration platform that models any application programming interface as an entity-relationship model. This technique allows an individual using an integration platform to map and transform the entity-relationship model without having to create any custom code. The user may specify target parameters as part of an ETL process, and the entity relationship model may allow appropriate data and API calls to be generated to pass the data to the specified target. By creating an entity-relationship model from any API, the technique further supports versioning, schema change resolution, compatibility detection and other features. Furthermore, data visualization software may use the entity-relationship model to allow users to explore and analyze the data represented in the entity-relationship model.

  • Publication number: 20240233283
    Abstract: Disclosed is a location tracking system and associated methods for precisely locating a target device with a recipient device via different forms of location tracking and augmented reality. The recipient device receives a first position of the target device over a data network. The recipient device is moved according to the first position until the target device is in Ultra-WideBand (“UWB”) signaling range of the recipient device. The recipient device then measures a distance and direction of the target device relative to the recipient device based on Time-of-Flight (“ToF”) measurements generated from the UWB signaling. The recipient device determines a second position of the target device based on the distance and direction of the target device, and generates an augmented reality view with a visual reference at a particular position in images of a captured scene that corresponds to the second position of the target device.

  • Publication number: 20240061817
    Abstract: A federation management service may receive an indication of multiple data sources to integrate into a federated application programming interface (API). One of the data sources is a database that is associated with an API schema that includes annotations that map elements of the API schema to the features of the database. The federation management services processes the API schema to generate the federated API. The federated API may receive a request for an element that is mapped to the feature of the database, generate a query based on the annotations of the API schema, and return a result based on the generated query.

  • Publication number: 20240054066
    Abstract: A federation management service may receive, via a user interface of the federation management service, a first user input indicating a selection of a testing environment for testing a federated application programming interface (API). The federation management service may receive, in response to the first user input, a portable binary file for deployment in a web browser of a client host. In some examples, the portable binary file may include a first set of scripts for orchestrating query requests for the federated API and a second set of scripts for orchestrating communications between the web browser of the client host and the first set of scripts. The federation management service may then execute, within the web browser of the client host, a query of the federated API using the first set of scripts and the second set of scripts.

  • Publication number: 20230091775
    Abstract: A computer-based system may be configured to collect metadata for each source and target defined for a data pipeline and formatting information (e.g., schemas, transformations, etc.) associated with each entity and field. During the definition of the pipeline, how the data will end up in the target may be defined, for example, by a user of the computer-based system via a GUI/interface and/or the like. Information (e.g., modification information, etc.) describing how the data will end up in the target may be defined, stored, and accessed to determine and/or track over which fields and entities are affected by the user-defined mutations and over which schemas. Lineage information (e.g., a genealogical tree, data lineage tracing, etc.) describing a data, version, and transformation may be generated and used to determine a source for a data record, how changes to the data record are related, how lineage evolved, and/or the like.

  • Patent number: 11413210
    Abstract: Improved customizable orthotic/prosthetic braces and a lightweight modular exoskeleton may aid individuals with lower limb motor impairment, including children. These customizable orthotic/prosthetic braces improve the strength and rigidity of such braces without a weight penalty. A structural frame is embedded between an inner shell and outer shell, which comprise materials that are easily moldable to conform to a user's limb. The lightweight modular exoskeleton system provides six (6) joint actuators, which are designed to be modular, that act as the active joints (e.g. hips, knees, and ankles) of the exoskeleton. Additionally, the exoskeleton may also provide four (4) passive joints for inversion/eversion of the legs and feet. Foot, crutch, and hip assemblies may also be provided for the exoskeleton.

  • Patent number: 11363407
    Abstract: Disclosed is a secure in-person dating and socializing platform. The platform may perform a check-in of a first user at a particular event based on messaging from a first device of the first user. The first device may receive messages from other devices of other users at the particular event that have previously checked-in to the particular event. Each message may provide a status for a different one of the other users. The first device may determine a location of each of the other devices based on signaling characteristics associated with receiving each message, may determine an area falling within a field-of-view of the first device camera, and may provide an augmented reality presentation of the camera feed with a visual indicator for the status of a second user at a particular location in the field-of-view that maps to the location of a second device of the second user.

  • Publication number: 20220079527
    Abstract: A method removing artifacts from neural signals comprises receiving electroencephalography (EEG) data from an EEG system and providing the EEG data to a unified artifact removal framework for cleaning artifacts. The EEG data is provided to a first cleaning framework utilizing the first reference to clean first artifacts from the EEG data, and the outputting the EEG data from the first cleaning framework to a second cleaning framework. The second cleaning framework may operate in a similar manner utilizing second reference to clean second artifacts from the EEG data. This general process may be repeated as desired to clean various artifacts from EEG data, when a suitable reference for the artifacts to be removed is utilized. The frameworks utilize H? method or filtering involving a H? adapting rule to properly weigh the reference, and combining the subsequent output with incoming EEG data results in the desired removal of artifacts.

  • Patent number: 11052249
    Abstract: Neuromuscular stimulation is widely used for rehabilitation and movement assist devices, due to its safety, efficacy, and ease of operation. For repeatable and accurate muscular contractions, a voltage controlled current sources (VCCS) with high compliance is required. Conventional VCCS design requires high-voltage rated operational amplifiers, which are expensive and consume large power. Moreover, conventional stimulators are not viable for simultaneous stimulation of muscle synergies, as they require multiple VCCS operating at the same time. This invention presents a neuromuscular stimulator with a multistage driver circuit wherein, a VCCS connected to an output driving stage comprising of folded-cascode transistor buffers and a bidirectional current mirror circuit. The multistage driver circuit uses inexpensive low-voltage rated operational amplifiers that consume 95% less power.
