Abstract: A digital twin modeling method to assemble a robotic teleoperation environment, including: capturing images of the teleoperation environment; identifying a part being assembled; querying the assembly assembling order to obtain a list of assembled parts according to the part being assembled; generating a three-dimensional model of the current assembly from the list and calculating position pose information of the current assembly in an image acquisition device coordinate system; loading a three-dimensional model of the robot, determining a coordinate transformation relationship between a robot coordinate system and an image acquisition device coordinate system; determining position pose information of the robot in an image acquisition device coordinate system from the coordinate transformation relationship; determining a relative positional relationship between the current assembly and the robot from position pose information of the current assembly and the robot in an image acquisition device coordinate syste

Abstract: Various implementations disclosed herein include devices, systems, and methods that present a view of a device user's face portion, that would otherwise be blocked by an electronic device positioned in front of the face, on an outward-facing display of the user's device. The view of the user's face portion may be configured to enable observers to see the user's eyes and facial expressions as if they were seeing through a clear device at the user's actual eyes and facial expressions. Various techniques are used to provide views of the user's face that are realistic, that show the user's current facial appearance, and/or that present the face portion with 3D spatial accuracy, e.g., each eye appearing to be in its actual 3D position. Some implementations combine live data with previously-obtained data, e.g., combining live data with enrollment data.

Abstract: An assessment and control method, system and device for time-energy efficiency of CNC machine tools. The method comprises: comprehensively analyzing the influence of factors of the startup rate and extra startup frequency of a CNC machine tool on the energy efficiency of the CNC machine tool, and constructing a mathematical model of the time-energy efficiency of the CNC machine tool and the startup rate and extra startup frequency of the CNC machine tool. The time-energy efficiency of the CNC machine tool is monitored to realize the overlimit warning function for the time-energy efficiency of the CNC machine tool to finally control the time-energy efficiency of the CNC machine tool within a target range. The present invention analyzes the influence of the downtime loss of the CNC machine tool on the energy efficiency of the CNC machine tool, and can realize overlimit warning for time-energy efficiency of the CNC machine tool.

Abstract: An automatic driving track obtaining method and apparatus are provided. The method includes: obtaining a driving style coefficient of a driver of a vehicle A (S101); calculating a cost function of the driver of the vehicle A based on the driving style coefficient of the driver of the vehicle A (S102), where the cost function is used to represent costs paid when the vehicle A travels from an initial node to a current node in a driving track of the vehicle A; and obtaining the driving track of the vehicle A on a first three-dimensional spatial-temporal map through calculation according to the cost function (S103). The driving track obtained by using the method and the apparatus can match driving styles of all drivers. This improves driver satisfaction on the driving track, and lessens a running-in period in which the driver performs automatic driving.

Abstract: The removal of particulate contaminants, such as dust particles, from the surface of a semiconductor wafer is achieved by pressing a soft adhesive layer against the wafer surface, leaving it in place for a short time and then removing it. The adhesive is brought to the wafer surface on a flexible medium which serves as a backing layer and to whose other side pressure can be applied. To remove the adhesive, the backing layer is peeled off, either by pulling on one end or by passing a sticky roller over it. The operation may be performed in air or under vacuum.
