  • Publication number: 20250216856
    Abstract: A method and system for navigating a robot 100 in a designated environment are provided herein. In an embodiment, the method comprises: selectively identifying reference features from a scale plan of the designated environment; generating a topometric map 178 of the designated environment, the topometric map 178 being associated with the identified reference features; generating an initial navigation path 176 of a local region 174 from the topometric map 178; as the robot 100 navigates along the initial navigation path 176 of the local region 174, detecting onsite reference features of the local region 174 that correspond to the identified reference features of the scale plan; and updating the topometric map 178 based on the correspondence to generate a regional path plan 188 to guide the robot's direction in the local region 174.

  • Publication number: 20250148813
    Abstract: In cell instance segmentation of an original cell image obtained by microscopy, the original cell image is rotated by a rotation angle to yield a rotated cell image. A first machine-learning model for cell instance segmentation processes the original and rotated cell images such that effectively, horizontal and oblique boxes are used in bounding cells of the original cell image for enhancing cell-segmentation accuracy. A set of predictions is generated for each cell instance identified from the original and rotated cell images, yielding a plurality of sets of predictions for all cell instances. The plurality of sets of predictions is processed to remove any set having predicted space not simply connected, any unwanted set classified by a second machine-learning model as a poor indicator according to a certain performance criterion, and any redundant set. The plurality of sets of predictions then produces a segmentation map for the original cell image.

  • Publication number: 20230401183
    Abstract: A method for detecting data drift between a first database and a second database involves obtaining (from the first database) and based on a change data capture (CDC) event generated in response to a change detected in the first database, a first record identified by the CDC event, obtaining (from the second database) a second record corresponding to the first record, transforming a data structure of the first record from the first database to the data structure of the second database generating a transformed record, and based on determining that a difference between the first record and a second record exists, reporting a presence of data drift.

  • Patent number: 11798015
    Abstract: The present disclosure includes computer implemented techniques for providing a survey to a user. In one embodiment, a software application receives an audio stream including utterances spoken by the user interacting with a voice-user interface of the application. The application then determines a set of paralinguistic features from the audio stream and estimates at least a first attribute of the user based on the set of paralinguistic features. The application selects survey content based on a value of the first attribute and transmits a survey including the selected survey content to the user.

    Abstract: A method may include selecting a cohort of entities for migration from a source storage repository to a target storage repository, obtaining a mapping between a source storage schema of the source storage repository to a target storage schema of the target storage repository, and migrating data for the entities in the cohort. Migrating the data of an entity may include copying, without locking the data in the source storage repository and in the target storage repository, the data from the source storage repository to the target storage repository, verifying, while the data is locked, that the data in the source storage repository is the same as the data in the target storage repository, changing, while the data in the source storage repository and the target storage repository is locked, an entity pointer for the entity to the target storage repository based on the verifying, and unlocking the data.

  • Patent number: 11756077
    Abstract: Embodiments disclosed herein select a content message to present to a user on a page of an application based on paralinguistic features of audio input received from the user for the application. The audio input is received via a microphone associated with a computing device. A feature extractor extracts paralinguistic features from the audio input. A predictive model determines a label indicating a measure of receptiveness to product placement (e.g., a predicted marketing outcome) based on the paralinguistic features. A content-selection component selects a content message to present to the user based on the label and based on a profile of the user.

  • Patent number: 11553852
    Abstract: A medical system for minimally-invasive measurement of blood flow in an artery (AT). An interventional device (IVD) with an optical fiber (FB) comprising a plurality of temperature-sensitive optical sensor segments, e.g. Fiber Bragg Gratings, spatially distributed along its longitudinal extension is configured for insertion into an artery (AT). A temperature changer (TC) is arranged in the WD to introduce a local change in temperature (?T) of a bolus of blood in the artery, to allow thermal tracking over time with the optical fiber (FB). A measurement unit (MU) with a laser light source (LS) delivers light to the optical fiber (FB) and receives light reflected from the optical fiber (FB) and generates a corresponding time varying output signal. A first algorithm (A1) translates this time varying output signal into a set of temperatures corresponding to temperatures at respective positions along the optical fiber (FB).
