  • Patent number: 8220112
    Abstract: A device for anchoring a strap to a structural member has a strap and a strap anchoring member fixed to the strap at a first end of the strap. The strap anchoring member has a length and a width, wherein the length is greater than the width. The strap anchoring member is folded to provide only two layers of the strap anchoring member enclosing an end region of the strap adjacent a first end of the strap. A secured portion of the strap anchoring member is proximal the first end of the strap with both layers of the strap anchoring member fixed to the strap providing a three layer structure. An unsecured portion of the strap anchoring member is distal from the first end of the strap. A second end of the strap may be fixed to an airbag used for protecting an occupant of a motor vehicle.

  • Patent number: 7977935
    Abstract: A linear motion sensor has two pairs of opposed spaced apart stacks of two simple two-pole bar magnets. Each stack has one shorter outer magnet and one longer inner magnet, with the outer magnets centered on the inner magnets. The poles of the magnets are oriented the same in each pair, but opposite with respect to the other pair. The shape of the magnets results in the magnetic fields produced by each pair of magnets being substantially outside of the magnets themselves, so that the load line for the combined magnets is above the knee in its B/H material demagnetization curve. The pairs of magnets define a gap therebetween in which a magnetic field sensor is mounted for travel. The shorter magnets are about one half the length of the longer magnets such that the magnetic field in the gap varies substantially linearly as the sensor moves along the gap.
