Abstract: Magnetic or electric field sensors are mounted against a material surface and used for stress, strain, and load monitoring of rotating components such as vehicle drive trains. The stationary sensors are mounted at multiple locations around the component and used assess the stress on the component at multiple rotational positions. The sensor response is typically converted into a material property, such as magnetic permeability or electrical conductivity, which accounts for any coating thickness that may be present between the sensor and mounting surface. The sensors are not in direct contact with the rotating component and are typically mounted on an annular material or ring that encircles the rotating component. Measurements of the annular material properties, such as the stress, are related to the stress on the rotating component and discrete features on the component.

Abstract: An upper bundle steam generator cleaning, inspection, and repair system includes a deployment and support device receivable within the steam generator configured to raise and position a distal end of said device to the upper bundle region of the steam generator, a head subsystem connected to the distal end of the deployment and support device for at least one of cleaning, inspection, and repair of said upper bundle region, and a lateral support subsystem deployable to support said head subsystem within the upper bundle region of the steam generator and retractable to deploy said head subsystem up to the upper bundle region and to withdraw said head subsystem therefrom.

Abstract: An upper bundle steam generator cleaning, inspection, and repair system including a deployment support device receivable within the steam generator to raise a cleaning device, an inspection device, and/or a tool up to the upper bundles of the steam generator.

Abstract: An airspeed indicator with quantitative voice output converts an electrical or pressure value to an indicated airspeed value and provides the numerical airspeed value to the pilot vocally. The device uses a precision pressure transducer to convert pitot tube pressure to an equivalent electrical signal, which is used to operate an indicator on the instrument panel and to operate a voice synthesizer to announce the current airspeed value to the pilot, either through a speaker in the aircraft cabin, in the pilot's headset or in the device itself. The vocal output from the airspeed indicator can be enabled or disabled, according to the pilot's needs. The frequency with which the device provides updated airspeed values to the pilot can be adjusted to suit the pilot's preference.

Abstract: A tethering system for a floating boat dock that allows both vertical and horizontal motion of the dock in response to changes in water level while maintaining the dock in a constant position relative to the moving shoreline. The system comprises cables attached to earth anchors, maintained under constant tension and mechanically coupled to rolling ground contact elements that bear against the bottom of the body of water.
