A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

A blow-by gas filtration assembly (1) fluidly connects an internal combustion engine crankcase ventilation circuit to receive blow-by gases and filter from the gases the suspended particles contained therein. The filtration assembly (1) includes a hollow cylindrical filter group (2) which can be radially crossed by the blow-by gases. in addition, the filtration assembly (1) has a control group (3) that supports and commands in rotation the filter group (2) including: i) a hollow shaft (4) extending along the axis (X-X) in the filter group (2), defining an inner duct (400) fluidly connected with the central cavity (200) for the circulation of the blow-by gases. An electric motor (5) includes a stator (51) and a hollow rotor (52) operatively connected to the hollow shaft (4) to receive an electromagnetic control action from the stator (51) and command in rotation the hollow shaft (4) and thus the filter group (2).

An object of the present invention is to suppress conduction between an anode and a cathode caused by condensed water in an oil removal apparatus in which oil particles are trapped in a filter disposed between the anode and the cathode. A bipolar electrode having an anode and a cathode that extend in a flow direction of blow-by gas, and a filter formed from an insulator and disposed between the anode and the cathode of the bipolar electrode are housed in a case. Further, when the oil removal apparatus is installed in a vehicle, the bipolar electrode and the filter are disposed in the case so as to be arranged in a horizontal direction, and a space through which the blow-by gas flows is formed between a lower inner wall surface of the case, and the bipolar electrode and filter.

Disclosed is a blow-by device comprising a connection piece and a coupling piece that can be connected to each other. A ring is provided on which a connector collar for a connector is provided in order to establish an electrical connection in connection pieces that are connected to the coupling piece. The ring may be positioned on the connection piece.

An internal combustion engine includes a crankcase having first and second pluralities of openings. A oil separation module has at least one inlet housing that communicates with a oil separation filter and is connectable to at least one opening from the first plurality of openings or from the second plurality of openings to define a crankcase vent.

A filter cartridge for use in separating a hydrophobic liquid aerosol phase from a gas stream, as a crankcase ventilation filter for example, is described. The cartridge includes a media pack comprising filtration media surrounding an open interior and a first end piece. Various structure included on the first end piece is described. An example is a D-shaped projection. Also described is an assembly including the filter cartridge, specific features of a housing component of the assembly. Methods of assembly and use are also described.

A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

An internal combustion engine having an oil circuit, wherein the oil circuit is designed to supply at least one component of the internal combustion engine with lubricating oil, and at least one oil reservoir for providing the lubricating oil for the oil circuit, wherein there is provided at least one collecting container separate from the at least one oil reservoir, wherein lubricating oil in the oil circuit downstream of the at least one component can be collected in the at least one collecting container, and there is provided at least one removal device, by means of which at least a part of the lubricating oil collected in the at least one collecting container is removable from the at least one oil circuit.

A pressure-limiting valve for use in a gas line conveying a gas that includes aerosols. The pressure-limiting valve has a movable valve body, a valve seat, and a compressible coalescing medium placed therebetween. The valve body has passages and nozzle openings and the valve seat has through-holes. In the closed position, the valve functions in separator mode and in the fully open position, in impactor mode. The pressure-limiting valve according to the invention provides a more sensitive response to varying flow conditions, due to deviating surface profiles of the valve seat and coalescing medium, which provide intermediate stages of separator and impactor modes as a function of the volume of flow.

A method of removing oil from blowby vapors in an engine having a crankcase and an intake manifold includes filtering the blowby vapor from the engine crankcase to form a vapor depleted of oil and a collected oil. The vapor depleted of oil is communicated to the engine manifold. At high engine loads the collected oil is held in a chamber, and at low engine loads while the engine is still running, the collected oil is forced from the chamber back the crankcase.
