摘要:
In a device for processing a stereo audio signal having a first channel and a second channel the stereo signal is at first analyzed to obtain a measure for a quantity of bits required by a coder to code the stereo audio signal using a coding algorithm. The first channel and the second channel are then modified when the measure for the quantity of bits is larger than a predetermined value, the modification being performed in such a way that the energy of a sum signal of the first and the second modified channel is in a predetermined relation to the energy of a sum signal of the first and the second channel and that a difference signal of the first and the second modified channel is attenuated in contrast to the difference signal of the first and the second channel. Especially for audio coders requiring a constant output bit rate the side channel is attenuated in the case of stereo audio signals, the coding of which cannot meet the output bit rate of the coder, by which a stereo channel separation is abandoned for the benefit of an increased audio bandwidth or a reduction of quantizing disturbances, respectively.

The present invention relates to apparatus rating solar units and to a method for rating solar units that comprises multiple acquisition of at least one input parameter and a corresponding multiple acquisition of at least one output parameter in acquisition intervals, at least one acquisition interval being varied for purposes of subsequently acquiring at least one output parameter as a function of the minimum of one acquired input parameter.The invention also relates to a solar unit, to a computer program and to a computer program product with means implementing the rating method.
摘要:
A cylinder head for a water-called internal combustion engine has a combustion space. Due to radiant heat in the combustion space, a hot site develops at a wall in a cooling duct of the cylinder head, through which cooling water is flowing. Control measures are provided for a concerted flow of cooling water in the cooling duct and for cooling the hot site at the wall of said cooling duct.
摘要:
A reciprocating lens-like combustion space is formed in a piston internal combustion engine which is located with approximately one-half in a recess of the piston top and with approximately the other half in the cylinder head. By the dimensioning of the combustion space and the coordination thereof to the inlet and exhaust valve, a vortex flow is produced with a ring-shaped mixing zone of high fuel concentration, in which the ignition electrodes of two spark plugs are arranged diametrally opposite one another.

The invention concerns compositions comprising one or more viscous soluble fiber(s) and one or more viscosity-lowering protein(s) and their use in the prevention or treatment of metabolic syndrome and/or diabetes and/or for lowering blood cholesterol level.
摘要:
Sparks are generated in the ignition distributor of an internal combustion engine during the interruption of the high voltage current which lead to the formation of ozone. In order to remove this ozone causing strong oxidation and corrosion, rapidly out of the ignition distributor, the distributor housing is connected to the charging air line leading from the turbocharger to the cylinder head of the internal combustion engine and is scavenged by charging air.
摘要:
A valve guidance for an exhaust gas valve in the form of a disk valve of an internal combustion engine which is used for the control of an exhaust gas channel of an internal combustion engine; a guide body with good heat-conducting and sliding properties serves as valve guidance. The guide body is coated at the inlet place of the valve stem either with a hard metal coating applied by plasma-spray process or with a hard metal sleeve.
摘要:
An air-cooled multi-cylinder internal combustion engine includes cylinder heads cast together in a cylinder head casting; the cylinder heads are cooled from the inside by an S-shaped air flow extending between the valves. The cooling air thereby flows-in through an inlet channel at the inlet side of the cylinder heads, is deflected through 90.degree. in a central connecting channel and after a once-more 90.degree. deflection flows into the atmosphere through outlet channels which are formed between the individually cast exhaust gas outlet channels.
