  • Publication number: 20220248862
    Abstract: A ready to assemble (RTA) bed structural system is disclosed wherein the structural system is adapted to be shipped in easy-to-assemble pieces which render the bed easier to form into a package in view of the fact that the longitudinal frame members of the bed frame can be folded in half such that the resulting package has half the longitudinal length of the ultimately assembled bed. In addition, several of the deck components of the bed can be folded together so as to effectively define an interior compartment within which other components of the bed can be housed. This effectively provides the package with a more compact footprint rendering the same easier and less costly to transport.

  • Patent number: 11379487
    Abstract: Enhancing a data query is provided. A knowledge base is searched for information corresponding to the data query. It is determined whether a query result is greater than a query result threshold level of information for the data query based on an identified query intent and keywords of the data query. In response to determining that the query result is not greater than the query result threshold level of information for the data query, a set of questions is sent to a personal digital agent of a client device that sent the data query for additional information based on the identified query intent and keywords. Analytic concepts answering the set of questions are received from analytic modules of the personal digital agent that are based on IoT-based personal data corresponding to a user of the client device. The data query is enhanced using the analytic concepts.

  • Patent number: 11348277
    Abstract: A method for estimating camera orientation relative to a ground surface. Line segments are detected from an image captured by a camera. A first virtual cube having three orthogonal vanishing points with a random 3D orientation is superimposed on to the image. The line segments of the image are classified grouped into 3D-directional groups. A second virtual cube is superimposed on to the image with an initial 3D orientation. An optimal 3D orientation of the second virtual cube is computed by iteratively changing the 3D orientation of the second virtual cube and measuring perpendicular distances of the three orthogonal vanishing points to the three line segment groups in each iteration starting with the initial 3D orientation, wherein the optimal 3D orientation of the second virtual cube being one that provides shortest perpendicular distances. Co-variances of the orthogonal vanishing points of the second virtual cube at the optimal orientation are computed.

  • Patent number: 11288566
    Abstract: An approach is provided for domain-specific chatbots that employ distributed natural language classifiers (NLCs). A NLC included in a first chatbot is executed, which generates a first intent of a question and a first confidence that the first intent is an actual intent of the question. Based on a determination that the first confidence does not exceed a threshold, the question is broadcasted to other chatbots. A second confidence that a second intent is an actual intent is received from a second chatbot in response to the broadcast, and is determined to exceed the threshold. An association among the question, the second chatbot, the second confidence, and the second intent is stored in a memory cache included in the first chatbot. A response to the question is generated based on the second intent. The response is presented to a user from the first chatbot.

  • Publication number: 20220051430
    Abstract: An iterative multi-image camera orientation estimation comprising: capturing an image of a scene before the camera; detecting line segments in the scene; computing a maximum likelihood (ML) camera orientation by maximizing a likelihood objective by rotating the camera's X-Y-Z coordinate system such that it is being optimally aligned with the line segments in at least two of the frontal, the lateral, and the vertical orthogonal directions; estimating a maximum a-posteriori (MAP) camera orientation that maximizes an a-posteriori objective such that the MAP camera orientation is an optimal value in between the priori camera orientation and the ML camera orientation, and is closer to the one with smaller uncertainty; iterating the multi-image camera orientation estimation with the priori camera orientation and its corresponding priori camera orientation uncertainty set to the computed MAP camera orientation and its corresponding uncertainty respectively until the uncertainty is lower than a threshold.
