  • Patent number: 8350663
    Abstract: A method for creating and a device for a rotary switchable multi-core element, permanent magnet-based apparatus, for holding or lifting a target, comprised of two or more carrier platters, each containing a plurality of complementary first and second core elements. Each core element comprises permanent magnet(s) with magnetically matched soft steel pole conduits attached to the north and south poles of the magnet(s). Core elements are oriented within adjacent carrier platters such that relative rotation allows for alignment in-phase or out-of-phase of the magnetic north and south fields within the pole conduits. Aligning a first core element “in-phase” with a second core element, that is, north-north/south-south, activates that core element pair, allowing the combined magnetic fields of the pole conduits to be directed into a target. Aligning the core element pair “out-of-phase,” that is, north-south/south-north, deactivates that core element pair by containing opposing fields within the pole conduits.

  • Patent number: 8256098
    Abstract: A method for producing a switchable core element-based permanent magnet apparatus, used for holding and lifting a target, comprised of two or more carrier platters containing core elements. The core elements are magnetically matched soft steel pole conduits attached to the north and south magnetic poles of one or more permanent magnets, inset into carrier platters. The pole conduits contain and redirect the permanent magnets' magnetic field to the upper and lower faces of the carrier platters. By containing and redirecting the magnetic field within the pole conduits, like poles have a simultaneous level of attraction and repulsion. Aligning upper core elements “in-phase,” with the lower core elements, activates the apparatus by redirecting the magnetic fields of both pole conduits into the target. Anti-aligning upper core elements “out-of-phase,” with the lower core elements, deactivates the apparatus resulting in pole conduits containing opposing fields.

  • Patent number: 5618613
    Abstract: A fiber reinforcing mat is used proximate a through hole in an automotive structural element in order to reinforce the element in the area approximate the through hole. The fiber reinforcing mat is comprised of a warp having a plurality of radially extending loops and a weft which is woven through the loops in a spiral fashion. Since the weft is configured as a spiral, weft material is more dense in the area close to the through hole than in the area distal of the through hole. Consequently, the stiffness of the structural element decreases gradually in radial directions away from the through hole.

  • Patent number: 5600300
    Abstract: An arrangement for indicating that an electrical connection is not established between first and second electrical circuit components includes a shorting contact which is disengaged upon first and second electrical connectors establishing a connection. As long as the shorting contact is engaged, current flows to an indicator lamp indicating that the first and second connectors are disengaged. This arrangement is utilized to notify the operator of a motor vehicle that a connector is disengaged from an air bag system diagnostic module and needs to be reconnected so that an igniter disposed within an air bag in the vehicle is connected to an inertia sensor which energizes the igniter in order to cause a gas expansion to inflate the air bag. When the connector is connected to the module, the lamp is not illuminated.

  • Patent number: 5542280
    Abstract: A gauge, system and method are disclosed for determining the accuracy and performance of a gauge by determining the angular deflection of the gauge needle in response to a known input signal. A frequency generator supplies a predetermined frequency signal or a controller supplies an input signal to a gauge motor which causes deflection of the gauge needle. A video camera is used to capture a video frame corresponding to the visual data indicating the needle deflection. The needle includes a head portion and a remote portion, such as a hub or tail, which show up as high intensity values against the low intensity background in the video frame. The pixel intensity values around the perimeter of a selected portion of the frame are scanned to determine the location of maximum intensity pixels which correspond to either the head or the remote portion of the needle. Alternatively, the image is scanned in terms of color.

  • Patent number: 5541521
    Abstract: Development of worst case operating environment, interfering parameters of a test item, is effected by a decoupling device. The device includes a series of resonators configured and interconnected in a particular manner along with a shunt capacitance. Each resonator has a torroidal core formed from a ferrite composition. When connected between the test item and its support system, the device provides such an impedance to signals other than those needed for normal operation, that the highest noise voltage levels emit from the test item. These levels permit developing repeatable worst case interference parameters which provide a guide for modifying the test item circuit components and connectors so as to minimize the effects of generating EMI sources or to immunize susceptible receptors within the test item.
