US Classification:

731181

Abstract:

An apparatus and method for determining an approximation to a measure of the volatility of fuel on-board a vehicle having an internal combustion engine. The method includes the steps of measuring at least one characteristic of the fuel corresponding to a temperature of the fuel, a volume of the fuel, and a concentration of oxygenates within the fuel; determining an approximation of the a measure of the volatility of the sample volume of fuel using a linear function based on the at least one measured characteristic of the fuel corresponding to temperature, volume, and concentration of oxygenates of the fuel. Preferably, at least one temperature measurement is associated with a predetermined volume of the sample as the sample is evaluated. The method can include determining whether a fuel contains ethanol, and if not, whether the fuel is a winter blend of fuel or a summer blend of fuel. The method to determine whether ethanol is present can include the steps of bringing the fuel into contact with a sensing element; measuring a characteristic of the fuel corresponding to concentration of oxygenates, such as the change in capacitance or resistance of the sensing element; and calculating the dielectric constant or the conductivity of the sample respectively.

Abstract:

A compact ceramic fuel property sensor comprises a plurality of laminated ceramic layers. The heater, temperature sensor, and capacitance measurement electrodes are embedded between the layers. The capacitance electrodes include interdigitated electrodes and fuel traps for containing a sample of liquid fuel disposed between the interdigitated electrodes. The dimensions of the fuel traps are selected so that the fuel traps remain filled with liquid after said sensor has been bathed in fuel. A method for monolithically preparing the sensors provides a reduced cost method and a sensor that can survive indefinitely in liquid fuel.

Abstract:

A chemical vapor sensor is provided that measures a chemical species of interest with high sensitivity and chemical specificity. In an aspect, an ethanol vapor sensor is provided, sized for being inconspicuous and on-board a vehicle, having a passive measurement mode and an active breathalyzer mode, for detecting a motor vehicle driver that exceeds a legal limit of blood alcohol concentration (BAC), for use with vehicle safety systems. For the passive mode, a vapor concentrator is utilized to amplify a sampled vapor concentration to a detectible level for use with an infrared (IR) detector. In an aspect, ethanol vapor in a vehicle cabin is passively measured and if a predetermined ethanol level is measured, a countermeasure is invoked to improve safety. In an aspect, an active breathalyzer is used as a countermeasure. The active breathalyzer can be imposed for a number of vehicle trips or for a predetermined time period.

Abstract:

A configurable gauge apparatus includes a flat panel display (FPD) for displaying a user-defined gauge face, a transparent panel spaced from the FPD through which the displayed gauge face is viewed, and a mechanical pointer disposed between the FPD and the transparent panel for indicating a current value of a parameter of interest. The pointer includes a stem and a hub that rotatably supports the stem, and the hub is mounted on the FPD or the transparent panel. Pointer position is regulated either magnetically with a pointer magnet and a magnetic field generator disposed behind the FPD, or electrically with a motorized hub activated with transparent conductors formed on the FPD or transparent panel. The stem of the pointer is illuminated by either the FPD, or a hub-mounted LED activated with transparent conductors. Transparent conductors are also used to form a sensor array for detecting pointer position.

Abstract:

A method to avert an unlawfully intoxicated driver from operating a vehicle is provided. The method utilizes a passive ethanol vapor sensor to measure ethanol vapor concentration in air from a vehicle cabin and imposes a safety response when the passive ethanol vapor sensor detects that a sample of vehicle cabin air indicates that a vehicle occupant exceeds the legal blood alcohol concentration (BAC) for a motor vehicle driver. The ethanol vapor sensor may have a passive measurement mode and an active breathalyzer mode. Ethanol vapor in a vehicle cabin may be passively measured and if a predetermined ethanol level is measured, a countermeasure is invoked to improve safety. An active breathalyzer may be used as a countermeasure. The active breathalyzer can be imposed for a number of vehicle trips or for a predetermined time period.
