    摘要： The pipeline leak detection and repair device is an autonomous machine that travels through a pipeline to detect very small leaks therein. The device also repairs those leaks with an on-board repair component. The repair occurs nearly simultaneously with the leak detection as the device passes the leak. The device includes a plurality of thin, flexible sensor leaves in a radial array. The leaves are positioned to place them nearly in contact with the inner surface of the pipe wall. Each leaf includes two sensors installed on its opposite surfaces. Flexure of the leaf due to changes in pressure gradient as the leaf passes a leak results in signals from the sensors being sent to an onboard processor. The processor determines the position of the affected leaf, and rotates a repair component to apply a pressure-sensitive tape patch over the leak as the repair component passes the leak.

    摘要： The pipeline leak detector is a mobile device having one or more pressure sensor arrays for travel within a fluid pipeline for leak detection in the pipe wall. The sensor array(s) is positioned close to the internal surface of the pipe wall, and rotates circumferentially about the surface of the pipe wall as the device travels through the pipe. The sensor array(s) thus describes a helical path along the pipe wall, covering the entire internal surface of the pipe wall with a minimal number of sensors. The device is supported by three wheels bearing against the internal surface of the pipe wall. A drive wheel provides motive power for the device. A driven wheel rotates as it travels along the pipe wall and communicates rotationally with the sensor array(s) to drive its rotation. The third wheel is an idler to stabilize the axial orientation of the device within the pipe.

    摘要： The dual resonator chamber with variable volume includes first and second housings. The second housing is slidably mounted within the first housing such that a second inner neck portion of the second housing is slidably mounted about the first inner neck portion of the first housing and forms a fluid-tight seal therewith. A sliding wall is slidably mounted within the second housing, dividing the interior thereof into upper and lower resonator chambers. At least one first actutator selectively adjusts the height of the sliding wall with respect to the second lower end of the second housing to selectively adjust volumes of the upper and lower resonator chambers. At least one second actuator selectively adjusts the height of the second housing with respect to the first housing to selectively adjust the neck length of the lower resonator chamber.

    摘要： The system with branched optical fibers provides diagnostics and measurement of static and/or dynamic parameters in structures and structural elements. The system includes a structural material or element having a branched optical fiber embedded therein. The branched optical fiber includes a primary optical fiber segment and at least one secondary optical fiber segment branching therefrom. One or more fiber Bragg grating sensors are arranged on, and are in optical communication with, the primary optical fiber segment and the at least one secondary optical fiber segment. A signal analyzer receives signals generated by the fiber Bragg grating sensors representative of a magnitude of the physical parameter of the structural element.

    摘要： The pipeline leak detector is a mobile device having a pressure sensor array for travel within a fluid pipeline for leak detection in the pipe wall. The sensor array is positioned close to the internal surface of the pipe wall and rotates circumferentially about the surface of the pipe wall as the device travels through the pipe, thus describing a helical path along the pipe wall to cover the entire internal surface of the pipe wall with a minimal number of sensors. The sensors comprise tubes with conical mouths, and flexible members and strain gauges within the tubes. Pressure changes due to leaks cause the flexible members to move, with the strain gauges sending signals to a central processor to indicate a leak. The device is supported by a drive wheel, a driven wheel, and an idler wheel bearing against the internal surface of the pipe and evenly circumferentially spaced.

    摘要： The fastener tension monitoring system provides for automatic notification when a structural tensile fastener, such as a bolt, is loosened. The system incorporates piezoelectric material in the core of the fastener shank or deposited around the shank. The piezoelectric material communicates electrically with an electrical storage device, a microprocessor, and a transmitter installed on the fastener head. Vibration or other changes in the tensile force developed by the fastener result in electrical impulses being generated by the piezoelectric material, generating electrical energy that is stored in the storage device and used to operate the microprocessor. In the event that an out of tolerance condition is sensed by the microprocessor, the transmitter is activated to send a signal to that effect. A receiver and computer are provided to monitor any such signals. The piezoelectric material may include pyroelectric material as well for the generation of electrical energy due to temperature changes.
