This method, which allows acquisition and computation of geometrical data of at least one pattern associated with an ophthalmic object (6) for manufacturing ophthalmic lenses similar to the object or complementary thereto, is of the type in which a device (12) for acquiring and computing geometrical data is used, which comprises: a transparent support (13) adapted for bearing an ophthalmic object; on one side of the support, means (17) for illuminating this support; on the other side of the support, a video camera (25) adapted for producing a video signal representative of at least one pattern associated with the ophthalmic object laid on the support; and signal processing and analysis means (27) receiving at the input the video signal produced by the camera, and adapted for computing and providing the geometrical data. The method is characterized in that: (a) a verification pattern independent of said geometrical data is traced on the ophthalmic object (6), this verification pattern being asymmetrical relatively to each of two axes perpendicular to each other; (b) the ophthalmic object is positioned on the transparent support (13) of the acquisition and display device (12); and (c) by means of said device (12), said verification pattern is optically captured and analyzed.

An industrial automation component may receive a first set of data associated with the industrial automation component, such that the industrial automation component is associated with a first industrial automation system. The industrial automation component may then receive a second set of data associated with one or more other industrial automation components, such that the one or more other industrial automation components are associated with one or more other industrial automation systems. The industrial automation component may then identify one or more similar patterns in the first set of data and the second set of data and adjust one or more operations of the industrial automation component based on the similar patterns.

A control system, includes a master control device configured to control a first controlled object based on time information output from a first clock unit, and a slave control device connected to the master control device via a network and configured to control a second controlled object different from the first controlled object based on control information transmitted from the master control device and time information output from a second clock unit. The time information of the first clock unit and the time information of the second clock unit are time-synchronized.
