Abstract: The invention relates to apparatuses for internal pipe non-destructive control of pipelines. Technical result is increasing of operational reliability of the internal pipe pig based on use of wireless means for transmitting data and control signals between both internal pipe measurement, diagnosis and control means outside the pig and on-board processing and storing means. An internal pipe pig comprises an electronic system of the pig, comprising wireless data transmission means which comprise at least one electromagnetic signal transmitter, measuring and measured data processing means comprising at least one measuring unit and at least one data processing unit, wherein the wireless data transmission means also comprise at least one high-frequency electromagnetic signal receiver for receiving the transmitted data, which is connected to the data processing unit.

Abstract: A method of multimedia (video, graphic, audio etc) data processing, comprises assignment of an area in the demonstration medium for receiving viewer's commands during the multimedia information demonstration process, for linking external applications, currently executed application, for an external application data placement and/or the results of work thereof. If the demonstration medium does not have a graphical representation, the assigned area is defined as a set of parameters, an interval of parameters, a group of parameters. A multimedia application of any type as well as the results of work thereof can be placed into the assigned area. A method for the formation in the demonstration medium contours of the assigned area which tracing an object of a complex shape in the displayed image, comprises the assigned area formation by one or more piecewise smooth arcs, adjusted to achieve the best coincidence with the contours of the traced object.
