  • Optical System, and Method for Identifying Fluid Through Said System
    Publication number: 20190003872
    Abstract: The present invention relates to the technological field of optical systems and refers to a device for identifying, at least one fluid, especially, fuel fluids in vehicle tanks. The device in question includes an optical guide having interaction surfaces and an emitter element emitting light beams and at least one receiving element of light beams. The information received from the receiving element includes the reflection emitted by interaction surfaces which are at the submersed region of the optical guide and indicates the type of fluid stored in the reservoir—for example: ethanol, gasoline or a mix of both. The interaction surfaces are inclined at different angles to provide total reflection for fluids with a different refractive index, including blends of fluids, to allow determination of the type of fluids according to the reflection by the interaction surfaces.

  • Optical System and Method for Measuring Fluid Level
    Publication number: 20190003873
    Abstract: The present invention relates to the technological field of meter systems and refers to a device for measuring the level of a fluid, especially, fuel fluids in vehicle tanks. The device in question including an optical guide having interaction surfaces and an light emitter element emitting light beams, an optical system including at least one collimator lens and a light diffuser, and at least one receiving element of the light beams, in which the information captured by the receiving element from the reflection reflected by the inclined interaction surfaces indicates the level of fluid stored in the reservoir. The inclined surfaces can have different angles (a), (?), or an intermediate angle between (a) and (?).

  • Fuel identification system and method
    Patent number: 8359168
    Abstract: The present invention relates to a fuel identification system and method normally applied to internal combustion engine vehicles of the flex-fuel type by means of which it is possible to identify the composition of the fuel used at each point in time, particularly the ratio used in a gasoline/ethanol blend or detect the presence of air or fuel in the vapor state in the fuel line, using the same device that heats the fuel.
