OFFSET CANCELLATION FOR AUDIO AMPLIFIER

Producing steel strip by strip casting, comprises placing metal melt from feed vessel to rotating casting strip of horizontal strip casting system by casting groove and siphon-like outlet area formed as casting nozzle under protective gas

Travel's clear path detection method for motor vehicle i.e. car, involves monitoring images, each comprising set of pixels, utilizing texture-less processing scheme to analyze images, and determining clear path based on clear surface

Illuminated display, i.e. for a motor vehicle instrument panel, has a diaphragm at the light outlet to prevent the driver being blinded by the light

Route lamp-retrofit lamp is provided with outer bulb and fluorescent lamp used in outer bulb, where outer bulb is glass bulb

Non verbal communication system, between a vehicle driver and electronic units, has a man machine interface to detect body movements for generating control signals

Sole structure for running shoe i.e. casual shoe, has elastic damping wedge arranged between outer sole and intermediate sole in rear shoe region, and wedge extending from middle-foot region towards rear ball of foot of shoe-wearer

Radio frequency high voltage supply, for a multi-pole ion store in mass spectrometry, uses a variable gap in the transformer ferrite core for stepless high voltage frequency adjustment

Gas insulated high voltage switchgear has two modules equipped with gas compartments acting as pressure container with two phase conductors

Device for measuring speed of poly-phase fluid flowing through pipe in given flow direction, has radiation source arranged to outer side of pipe, which emits photon radiation on poly-phase fluid

Absorption cup for oil level measuring instrument of engine, particularly in motor vehicle, has surface within upper range, which is arranged opposite to measuring channel in absorption cup in angular manner

Display device for motor vehicle, has display element for producing picture display, where display element has form of plate, and printed circuit board for switching configuration to operation of display element
