Abstract: A method for marking video media-content, comprising a plurality of frames, with a user ID. The method includes arranging a media-delivery platform to have a plurality of target devices connected thereto and further arranging the media-delivery platform to deliver the video media-content to a specified target device of the target devices, at which the user ID is being used. An image is overlaid over at least some frames of the plurality of frames as the video media-content is displayed at the specified target device. The image encodes the User ID and comprises a plurality of zones, the zones being arranged to encode the User ID. A visual property of the image is arranged to vary within at least some of the zones, and the image is arranged such that when the image is overlaid on the video media content, the image is at least substantially imperceptible to a user.

Abstract: A method includes: selecting a movement path for a moving component of a machine tool; either before or after the movement path, causing the moving component to make a first predefined movement; before the movement path, causing the moving component to make a second predefined movement; after the movement path, causing the moving component to make a third predefined movement; recording, using a computing device including one or more accelerometers, movement data resulting from the first, second and third predefined movements, and from the movement path; analyzing the movement data by finding waveforms to identify a start point, a finish point, and which one of the predefined movement paths in the set was selected; calculating timing information based on the identified start and end points, and the identified one of the predefined movement paths in the set; and determining performance limits of the machine tool based on the timing information.
