Oil status sensor e.g. for motor vehicle, has sensor fitted to oil module and provides lubrication to internal-combustion engine and for steering gear

Circuit arrangement for generating square pulses and improved compensation current sensor using same

Control device i.e. turnable regulator, for adjusting volume of car radio, has evaluation circuit coupled with control element, where evaluation circuit has micro-electro-mechanical sensor microphone for detecting movement noise of element

Capacitive level measuring device for e.g. fuel tank of motor vehicle combustion engine, has profile bars standing at certain angle from each other, and two surface electrodes are formed at each surface of profile bars

Method e.g. for estimating fuel introduction into motor oil, involves tracking whether diesel particulate filter is regenerated after a motor is turned

Circuit configuration for generating square wave pulses

Method for the Quantitative Determination of an Aging Effect on Motor Oil

Engine i.e. internal combustion engine, oil analyzing method, involves determining carbon black content in engine oil based on difference between two permittivities and difference between two viscosities

A method for quantitatively determining the aging influence on an engine oil

METHOD FOR THE QUANTITATIVE DETERMINATION OF THE EFFECTS OF AGEING ON MOTOR OIL
