Abstract: A method for identifying, classifying, extracting and resolving hidden entities from a data file includes searching for an executing copy of an application associated with the data file, initiating the application in a background if the application is not running, opening the data file for reading only, examining the data file for hidden entities, generating an examination log of incidents of hidden entities, and optionally, resolving the incidents of hidden entities.
Abstract: The invention relates to a variable valve train (1) for a cam-actuated lifting valve (13) of an internal combustion engine, which valve (13) is loaded by a closing spring (13a) acting against the direction of opening, with an approximately cylindrical force application element (2) located between a cam (14) and the valve (13), whose length can be adjusted hydraulically and whose exterior cylindrical wall face (3) is slidable in a fixed guide cylinder (4), said element (2) being provided with a pressure piston (6) longitudinally slidable in a cylinder (5), which piston (6) is adjacent to a pressure chamber (7) into which opens a pressure channel (8) departing from a port (9) in the wall face (3) of the force application element (2), a fixed pressure line (11) opening into the guide cylinder (4) in the area of the port (9), which line (11) can be subjected to hydraulic high pressure (pH) permitting hydraulic activation of the valve (13).
