Abstract: Methods and devices of determining a point for processing a workpiece. The methods include acquiring a plurality of model contour points representing a contour of a model associated with the workpiece and a model point representing a position for processing the model, acquiring a plurality of workpiece contour points representing a contour of the workpiece, and determining, based on the plurality of model contour points and the plurality of workpiece contour points, a workpiece point that corresponds to the model point for processing the workpiece.

Abstract: Methods and devices for determining a point for processing a workpiece. The methods include receiving an input representing an offset for adjusting a sample workpiece point, the sample workpiece point corresponding to a workpiece point for processing the workpiece, adjusting the sample workpiece point based on the input, so as to generate an adjusted sample workpiece point, and determining the workpiece point based on the adjusted sample workpiece point.

Abstract: Methods, apparatuses, systems, and computer readable media for managing a camera system. The camera system comprises at least a first camera and a second camera. In the method, a first position and a second position for a first object and a second object are obtained from the first and second cameras, respectively. The first and second objects are used for calibrating the camera system. After a movement of the first and second objects, a third position and a fourth position for the first and second objects are obtained from the first and second cameras, respectively. Here, a relative object position between the first and second objects remains unchanged during the movement. A relative camera position between the first and second cameras is determined based on the first, second, third, and fourth positions.

Abstract: Disclosed are methods and systems to facilitate automatic distribution of communications. In particular, a server may maintain data that indicates at least one registered subject-matter interest respectively for each of a plurality of users. Further, the server may receive a communication from a source user. The source user may be served by a particular base station. In response to receiving the communication, the server may identify one or more target users based on each target user (i) having at least one registered subject-matter interest that matches at least one subject-matter interest of the source user and (ii) being served either by the same particular base station that serves the source user or by a base station adjacent to the particular base station that serves the source user. The server may forward the communication to each identified target user.
