  • Patent number: 7234361
    Abstract: A sensor assembly for measuring force along an axis (F) comprises an inductance coil extending around the axis (F) for establishing a loop of magnetic flux looping axially through the coil and extending around the axis (F) to define a donut shaped ring of magnetic flux surrounding the axis (F). A core of magnetostrictive material provides a primary path for the magnetic flux in a first portion of the loop of magnetic flux and a magnetic carrier provides a return path for magnetic flux in a second portion of the loop of magnetic flux as the magnetic flux circles the coil through the core and the carrier. A first interface extends radially between the core and the carrier whereby the core and the carrier are urged together at the interface in response to a force applied parallel to the axis (F). Various embodiments or combinations of the core and carrier are illustrated in FIGS. 3–7.

  • Patent number: 7233852
    Abstract: A normally seated adult occupant of a vehicle seat is distinguished from a cinched car seat occupant based on the static seat force and first and second sets of identified dynamic characteristics that are respectively correlative of a normally seated adult and a cinched car seat. Confidence levels are assigned to the static seat force and each of the identified dynamic characteristics, and overall confidence levels for the two classifications are determined based on the assigned confidence levels. The overall confidence level for the adult occupant classification is compared with the overall confidence level for the cinched car seat classification, and the occupant is classified based on the highest overall confidence level.
