摘要： A sensor circuit is coupled to a sensing element for determining a property, such as a dielectric constant, of a fuel suitable where the dielectric constant is used in determining a concentration of ethanol in the gasoline/ethanol blended fuel. The circuit includes an excitation voltage signal generator, a synchronization trigger and a processing circuit configured to generate an output signal indicative of the fuel property (dielectric constant). The excitation voltage signal is applied to the sensing element to produce an induced current signal therethrough. The synchronization trigger is configured to generate a trigger signal when the excitation voltage signal crosses zero volts, at which time the real (resistive) component of the induced current signal is zero. The induced signal is therefore wholly representative of the imaginary component attributable to a capacitance of the sensing element in sensing relation with the fuel, which in turn is dependent on the dielectric constant (and thus ethanol concentration) of the fuel blend itself. The processing circuit is configured to sample the induced signal in response to the trigger signal and produce the output signal. The synchronization scheme provides for a simplified circuit arrangement since there is o need to decompose a signal combining real and imaginary components.

摘要： Soot content in Diesel engine lubrication oil is determined using electrical resistance measurements of the oil at high frequency. A sensor in the form of a capacitor is immersed in the oil, wherein the oil serves as a dielectric between the plates. The capacitance and resistance between the plates change as a function of engine oil condition. An inductor is placed in series with the sensor, and high frequencies are sweeped over a range to find resonance where the capacitive and inductive reactances cancel. At this frequency, the resistance of the oil is measured and the condition of the oil thereby determined.

摘要： A sensing assembly senses a level of a liquid in a reservoir. The sensing assembly includes a first input port for receiving a first input voltage signal. The sensing assembly also includes a second input port for receiving a second input voltage signal. An excitation circuit is electrically connected to the first and second input ports for receiving the first and second input voltage signals and for generating a first excitation signal and a second excitation signal. A receiving circuit is disposed adjacent the excitation circuit and defines a variable capacitance with the excitation circuit. The receiving circuit produces an output voltage variable with the level of the liquid in the reservoir due to capacitance changes between the excitation circuit and the receiving circuit. The receiving circuit includes a first receiving electrode extending through a sine wave form and a second receiving electrode extending through a cosine wave form. The capacitance changes are due to dielectric changes created by the presence of the liquid adjacent at least a portion of the sensing assembly.

摘要： A method to calculate a fuel driveability index (DI) value is provided from a sample of fuel in a container as tested by the industry standard ASTM D86 test providing particular temperature data at various percentages of evaporation as the container is heated. The particular temperature data provides a DI value. The same sample of fuel is tested on a sensor capable of retaining a predetermined volume of fuel. Temperature data is monitored at the same percentages of evaporation as the sensor is being heated. Correlation equations are mathematically calculated between the temperature data from the sensor relative to the particular temperature data from the ASTM D86 test and stored in the engine controller of a vehicle. The fuel from the fuel tank is tested by heating a similar on-board sensor having the predetermined volume of fuel and measuring the temperature data as a function of the remaining fuel in the sensor. The stored correlation equations are applied to the measured temperatures to provide the required temperature data to calculate the DI value for the fuel in the fuel tank.

摘要： A method for measuring fluid level uses data sensed by an oil level sensor to determine the level of oil in a motor vehicle oil pan. The oil level sensor can include a receiver tube oriented upright in the oil pan of the vehicle. A level tube is disposed in the receiver tube and below the level tube is a reference tube. A circuit is electrically connected to the tubes for outputting a signal representative of oil level in the oil pan. As the engine oil level decreases within the level tube, the output of the sensor drops. The method includes providing a series of signals to the sensor and recording the output from the sensor with the sensor in a variety of configurations. This information is then processed to determine the ratio of measured oil in the oil pan to the proper operating oil level.

摘要： A transmission clutch position sensor includes two Hall sensors located at opposite ends of a flux concentrator outside the casing of the transmission to sense a magnetic field generated by a magnet attached to the clutch piston. To reduce sensitivity to magnet-to-sensor gap tolerances, a ratio of the voltage of one Hall sensor to the sum of the voltages from both Hall sensors is used to correlate to the piston and, hence, clutch position.
