  • Patent number: 10670479
    Abstract: A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow coupling devices installed on different types of automobile cars and trucks.

  • Publication number: 20130092311
    Abstract: A thermal curing device is used to manufacture a high-pressure gas tank by FW method. In the thermal curing device, a tank vessel configured to have a fiber layer formed on its outer surface by winding carbon fibers impregnated with a thermosetting resin is held to be rotatable about a virtual central axis of the tank vessel. In the thermal curing device, the tank vessel is heated by a heating unit during rotation, so as to thermally cure the thermosetting resin in the fiber layer and thereby form a fiber-reinforced resin layer. A bubble removal process for preventing formation of air bubble in the fiber-reinforced resin layer is performed at multiple different stages during such heating.

  • Patent number: 8366851
    Abstract: This invention provides a method for manufacturing a tire in which the time necessary for the manufacture can be reduced without deteriorating uniformity in manufacturing the tire by a strip-build process. The method for manufacturing the tire comprises discharging a strip rubber (S) having a predetermined sectional shape by rubber discharging devices (A1, A2) while rotating a molding drum (B), and successively winding the discharged strip rubber (S) around the molding drum (B) to mold the rubber into a tire shape.

  • Patent number: 8313600
    Abstract: A method and system for fabricating a geometrically versatile composite lattice support structure having a seamless three-dimensional configuration. The lattice support structure is created by forming two or more cross supports, such as helical, longitudinal, circumferential and/or lateral cross supports, which intersect to form a plurality of multi-layered nodes. The lattice support structure may be designed without any protrusions extending outward from the overall geometry, thus enabling efficient tooling, and thus enabling ease of mass production. The lattice support structure may comprise a completely circumferentially closed geometry, such as a cylinder, ellipse, airfoil, etc. The method for fabricating the lattice support structure comprises laying up a fiber material, in the presence of resin, within rigid channels of a rigid mold, thus creating a green, uncured three-dimensional geometry of unconsolidated cross supports and multi-layered nodes where these intersect.
