USPTO Patent Full-text and Image Database

The present invention presents a universal reconfigurable video stream processing system where a digital twin is applied to 3D marker cloud mapping of a set of parameters, related to the current state of the monitored person (object). The invention includes two reconfigurable units, with at least one of these units being universally adjusted for any input-output mapping application with fixed input size, fixed output size and numerical values ordered by their meaning. Each reconfigurable unit includes at least one machine learning based mathematical model with a high number of parameters and non-linear functions performing as a universal approximator and ensuring high flexibility during training process. Each unit of the presented system, which includes a machine learning based mathematical model should be trained in advance of system execution with input-output mapping examples, where the range of the input values in the training example set should cover the range of the input values that will be used during system execution.

The presented invention includes the generation of cloud points, the identification of objects in the cloud points, and, in this case, finding the positions of objects in cloud points. In addition, the invention includes capturing images, data streaming, and digital image processing in different points of the system, and calculation of the position of objects. The invention includes the usage of cameras of mobile smart devices, smart glasses, 3D cameras, but not necessarily. The data streaming provides video streaming and sensor data streaming from mobile smart devices. The presented invention further includes cloud points of buildings in which the positioning of separated objects could be implemented. It also consists of the database of cloud points of isolated objects which help to calculate the position in the building. Finally, the invention comprises the method of objects feature extraction, comparing in the cloud points and position calculation.

The invention concerns a software based system for computer-aided design (CAD) that includes user interface tailoring and methods for continuously evaluating the learning progress of the user and increase work productivity by searching for the patterns in the user input to predict the goal of user actions and propose next action to reach the goal in optimal way. Components of the presented invention relate to collection of the different user input including at least eye tracking and user focus and attention related features; analyzing continuously user's behavior to evaluate user learning progress and work productivity related to the computer-aided design tool; monitoring user interface components that are used by the user; searching for the patterns in user behavior; tailoring user interface controls to maximize a work productivity at the same time increasing user's qualification profile. The core of the invention comprises gaze tracking as an input component for better user activity and performance tracking, component for features extraction fusion of different types user input, continuously monitored users qualification profile and two classifiers making decision on user interface complexity level and a set of most relevant graphical user interface controls for the next user action.

A multi-spoke-type ultrasonic motor ahs a rotating shaft, a fastening sleeve cylinder, a spring, a rotor, a stator, a fastening screw, and piezoelectric ceramics. The rotor, the stator, the spring, and the fastening sleeve cylinder are sequentially connected via the rotating shaft. The stator is an annular metal plate having internal spoke-like teeth. The upper surface and the lower surface of the stator are provided with identical stator spoke-like teeth for contacting the rotor. The rotor and the stator are in close contact under the effect of the prestressing of the spring. Ther piezoelectric ceramics are annular plates; upper and lower plates are affixed on the upper and lower surfaces of the stator. The is capable of increasing the output power of the ultrasonic motor.
