  • Patent number: 11054273
    Abstract: Embodiments herein disclose methods and systems for generating a 2D-navigation map for collision-free navigation by a plurality of robots. Initially, a 2D-navigation map generator executing at a cloud map server initiates a particle simulation to add a plurality of bubbles to an image of an area. Next, the 2D-navigation map generator executing at the cloud map server, processes the bubble simulation to determine a set of bubbles from the plurality of robots on the image that are overlapping free spaces of the area in the image. Next, the 2D-navigation map generator executing at the cloud map server, generates the 2D-navigation map by connecting the set of bubbles using a plurality of edges, wherein the plurality of edges indicate a navigation path to navigate within the area. Finally, based on the generated 2D-navigation map, the plurality of robots traverses from a current location to another location.

  • Patent number: 11013429
    Abstract: A method to identify feature points associated with the heart valve movement, heart contraction or cardiac hemodynamics is revealed. The mechanocardiography (MCG) is a technology that makes use of vibrational waveforms acquired using at least one gravity sensor attached on one of the four heart valve auscultation sites on the body surface. The data of the electrocardiography (ECG) is recorded simultaneously with the MCG The feature points are identified by comparing P, R and T points of synchronized ECG with the MCG spectrum. By the time sequences and amplitudes of the feature points, the method provides additional clinical information of cardiac cycle abnormalities for diagnosis.

    Abstract: Embodiments of the present invention provide a two-phase process for searching the root causes of the yield loss in the production line 100. In a first phase, process tools and their process tool types that are likely to cause the yield loss are identified, and in a second phase, the process parameters that are likely to cause the yield loss within the process tool types found in the first phase are identified. In each phase, two different algorithms can be used to generate a reliance index (RIk) for gauge the reliance levels of their search results.
