  • Patent number: 7324900
    Abstract: A distributed sensing system and method improves sensing of events that may require restraint deployment in a vehicle by distinguishing between deployment events and non-deployment events using data from more than one sensor. A transmission check process continuously monitors an incoming signal from a sensor and counts the number of data samples that exceed a selected value using a counter. If the counter value exceeds a selected threshold, the system indicates that the transmission check is fulfilled and allows deployment of the restraint. A correlation acceleration difference (CAD) algorithm calculates a CAD term corresponding to a degree of intrusion of a foreign object into a vehicle at a given time. Acceleration data from sensors disposed at supporting sides of the vehicle are checked if they respond to an event, and the absolute values of the acceleration data are subtracted from each other to obtain an absolute difference from which the CAD term is calculated.

  • Patent number: 7320255
    Abstract: The magnetometer assembly according to this invention includes a first coil assembly and a second coil assembly for detecting separate magnetic fields along an axial portion of a torque transducer. The first and second coil assemblies are driven by independently adjustable circuits. Each of the circuits are independently adjustable to adjust the gain that is distributed to each of the first and second coils. This provides for an adjustment and precise alignment of a magnetic field generated by the first coil and the second coil assembly such that external magnetic fields can be cancelled providing increased accuracy and reduced hysteresis effects.

  • Publication number: 20080012554
    Abstract: The present invention includes a rotary sensing system that includes a shaft, a magnet encircling the shaft, a pair of plates, each of which is positioned near distal ends of the magnet, and at least one sensing device. The magnet generates a magnetic field, the angle of which changes as the shaft rotates. The pair of plates directs the magnetic field generated by the magnet towards the at least one sensing device. The at least one sensing device is sensitive to the changes in the angle of the magnetic field, which are indicative of an angular position of the shaft.

  • Publication number: 20080011692
    Abstract: A cyclonic separator (10) separates contaminants from liquid fuel. The separator includes a body (12) having a base portion (14) and sidewall structure (16) extending from the base portion. The base portion and sidewall structure define an internal volume (V). An inlet port (18) in the body communicates with the internal volume, and an outlet port (20) in the body also communicates with the internal volume. The sidewall structure is constructed and arranged to cause fuel, containing a mixture of liquid fuel and contaminants, that enters the inlet port, to move in a generally circular manner in the internal volume so that the contaminants (P) separate from the liquid fuel, with the contaminants settling in the base portion and the liquid fuel (F?) moving through the outlet port.
