  • Publication number: 20020092721
    Abstract: A magneto-rheological (MR) damper provides a higher than minimum level of damping when a power source to the MR damper is not supplying a control current. The present invention damper includes magnets positioned to direct a magnetic flux across a MR fluid path. The fluid path is created when a rod and piston assembly stroke the fluid though a control valve assembly attached to a damper chamber causing a resistance to MR fluid flow. An electric coil cancels an affect of the permanent magnets when the control current is available to allow a control circuit more operating range. The permanent magnets allow for damping when no control current is available.

  • Patent number: 6421791
    Abstract: A distributed computer-implemented diagnostic system for determining a diagnostic state of a component. The component exhibits measurable characteristics. The system includes a database that stores reference component characteristic data. A computer server is connected to the database, and a computer client is connected to the computer server via a network. The client computer provides data requests to the server computer in order to retrieve the component characteristic data from the database. A portable computer is connected to the computer client in order to have data access to the retrieved component characteristic data and to provide the component characteristic data for performing diagnosis. The diagnostic state of the component is determined based upon the retrieved component characteristic data as provided by the portable computer and upon at least one of the measurable characteristics of the component.

  • Patent number: 6421790
    Abstract: A method and circuit for determining the health of a microcontroller is a bus having a data line and instruction line. A first CPU is coupled to the bus. A reference memory stores a reference signature. A shift register is coupled to the bus and generates a second signature in response to the data line and instruction line. A controller is coupled to the register and the reference memory for controlling reading of the data line and instruction line. The controller compares the reference signature to the second signature. The controller generates a fault signal when the reference signature is unequal to the second signature.
