Abstract: Linear velocity sensor and method for reducing non-linearity in the output signal of the sensor are provided. The sensor comprises a ferromagnetic housing 22 including an opening. The sensor further comprises a spool 32 disposed in the housing. The spool includes a bore 30 for receiving a slidable ferromagnetic rod 26. The ferromagnetic rod may be extendable through the opening in the housing. A magnet 28 is mounted at the one end of the rod distal from the opening when the rod is substantially inserted in the bore. A coil 50 is wound on the spool. The number of turns of the coil is arranged to taperingly increase as the coil progresses from an end of the spool proximate the opening in the housing to the opposite end of the spool. The tapering arrangement for the number of turns of the coil is selected to reduce non-linearity of an output signal of the coil indicative of linear velocity.

Abstract: An apparatus 10 monitors at least one fuel quality characteristic of fuel passing through a fuel delivery system 12 of a motor vehicle. The apparatus 10 includes a fuel rail assembly 18 connectable to the fuel delivery system 12 of the motor vehicle. A fuel rail assembly 18 has at least one housing 14 associated with either a pressure regulator or an accumulator. A sensor is associated with the fuel rail assembly 18 for measuring at least one characteristic of fuel quality of fuel passing through the fuel rail assembly 18 . At least one characteristic includes temperature and/or impedance. The sensor 16 can include a pair of plates 20, 22 spaced from one another by a gap of between approximately 0.5 mm to approximately 1.0 mm, inclusive, for measuring impedance across the gap.
