Abstract: A fiber-optic sensor matt detects movements of a person on the matt that cause microbending of a fiber-optic cable that is arranged into a symmetric pair of radial ring groups within the matt. There are no cross-over points or overlapping of the fiber-optic cable within the symmetric pair of radial ring groups that could cause fiber wear and noisy readings. Microbending of the fiber-optic cable pressed into a mesh modulates the light intensity received, which is analyzed to extract both respiration and heart BallistoCardioGram (BCG) waveforms by convolution with Daubechies dB5 wavelet and scaling functions. The reconstructed level-4 detail waveform is output as the extracted BCG, while the reconstructed level-6 approximation waveform is output as the extracted respiration waveform. Respiration and heart rates and variations can be generated from the extracted waveforms. An integrated Fast Wavelet Transform (FWT) using dB5 wavelet thus generates both respiration rate and heart rate.

Abstract: A data-centric network and non-Real-Time (RT) RAN Intelligence Controller (RIC) architecture are described. The data-centric network architecture provides data plane functions (DPFs) that serve as a shared database for control functions, user functions and management functions for data plane resources in a network. The DPFs interact with control plane functions, user plane functions, management plane functions, compute plane functions, network exposure functions, and application functions of the NR network via a service interface. The non-RT RIC provides functions via rApps, manages the rApps, performs conflict mitigation and security functions, monitors machine learning (ML) performance, provides a ML model catalog that contains ML model information, provides interface terminations and stores ML data and Near-RT RIC related information in a database. An ML training host trains and evaluates ML models in the catalog, obtains training and testing data from the database, and retrains and updates the ML models.

Abstract: The present teaching relates to method, system, medium, and implementations for estimating 3D coordinate of a 3D virtual model. Two pairs of feature points are obtained. Each of the pairs includes a respective 2D feature point on an organ observed in a 2D image, acquired during a medical procedure, and a respective corresponding 3D feature point from a 3D virtual model, constructed for the organ prior to the procedure based on a plurality of images of the organ. The depths of the first and the second 3D feature points are substantially the same. A first 3D coordinate of the first 3D feature point and a second 3D coordinate of the second 3D feature point are automatically determined based on the pairs of feature points so that a first distance between the determined first 3D coordinate and the determined second 3D coordinate equals to a second distance between a first actual 3D coordinate of the first 3D feature point and a second actual 3D coordinate of the second 3D feature point in the 3D virtual model.
