Abstract: The pipeline leak detector travels through a pipeline passively due to the flow of liquid through the pipeline. The device includes leading and trailing rings shaped to produce hydrodynamic resistance in order for the device to be carried through the pipeline. Wheels are provided about each ring, with at least one wheel having an odometer to measure distance traveled through the pipe. The rings are joined by a plurality of axially oriented connecting rods. A plurality of sensing elements extend between the rings. Each sensing element has a thin laminate of a piezoelectric film sandwiched between two electrically conductive layers, with an electrically insulating coating on the outside of each conductive layer. One of the rings includes microelectronic circuitry for data acquisition and storage.

Abstract: The add-on heat sink includes an elongate base having a plurality of fins extending from a surface thereof. A magnetic layer is disposed on the bottom of the base, which permits the add-on heat sink to be installed on any ferromagnetic heated surface. The magnetic layer is composed of either a polymer matrix having a plurality of thermally conductive structural components and a plurality of magnetic particles dispersed therein, or a thermally conductive polymer having magnetic particles dispersed therein. Alternatively, if the heated surface is not ferromagnetic, the heat sink may be magnetically attached by adhesively attaching mating magnetic and ferromagnetic pads to the heat sink and to the heated surface. This configuration allows the add-on heat sink to be installed with minimal footprint. Optionally, a fan may be magnetically attached to the heat sink to cool the heated surface by both conduction and convection.

Abstract: System for pipeline rehabilitation. The system includes repairing a leak in a pipe using a pair of substantially semi-cylindrical parts connected through a compliant joint. When the parts are compressed, the semi-cylindrical parts form a cylinder whose outside diameter is less than the inside diameter of a pipe with a defect thereby allowing the cylinder to be inserted into the pipe at a location of a leak. Once in place, the parts engage the inside surface of the pipe when the compression is released thereby to seal the leak.

Abstract: The system for delivery of insecticide provides a portable enclosure for delivering insecticide to an infested tree trunk. The system includes an annular shell disposed around with the trunk of the tree that defines an annular tank. An annular base supports the wall(s) of the annular shell and has a liquid impermeable membrane attached thereto that can be wrapped around the base of the tree trunk to prevent pesticide seepage into the ground. A pump delivers insecticide into the annular tank at an upper end of the tank. A drain hose attached to the base of the tank returns insecticide to the pump for recirculation. The pump is actuated in pulsating mode to agitate insecticide in the tank, causing waves of sufficient pressure to induce the insecticide to penetrate deeply through any bores in the trunk to kill both adult insects and larvae.

Abstract: The present invention is embodied in an actuator arm which is mounted to a primary actuator. The primary actuator positions the actuator arm, with a read/write head mounted to the actuator arm, across a data storage disk. The actuator arm comprises an inboard portion, an outboard portion and a pair of bimorph actuators. The inboard portion has a longitudinal axis and is attached to the primary actuator. The outboard portion has the read/write head mounted onto it. The pair of bimorph actuators are deflectable together in a common direction and are connected between the inboard and the outboard portions. Upon deflection of the bimorph actuators in the same direction, the outboard portion is translated along an at least nearly straight line transverse to the longitudinal axis of the inboard portion. This transverse motion allows the read/write head to be kept substantially within a plane parallel to the surface of the data storage disk, preventing damage caused by possible contact between slider and the disk surface from rolling the slider due to out-of-plane motions. Further, the use of bimorph actuators provide increased displacements of the read/write head. Also, since the head displacement is not a function of microactuator's position along the actuator arm, the actuator arm can be shorter, allowing for use in compact disk drives.

Abstract: Multiple Helmholtz resonators are combined serially and dynamically to mitigate and/or overcome acoustic noise filtering problems. One Helmholtz resonator is attached to a duct having an acoustic flow path channel containing undesired acoustic signals (noise) and is considered to be an immovable Helmholtz resonator with respect to that flow channel, while at least one movable Helmholtz resonator is movably and acoustically coupled to the immovable Helmholtz resonator. The immovable and movable Helmholtz resonators are acoustically coupled together to adjustably filter two resonant frequencies in the flow path channel with a feedback control system that adjusts the position of the movable Helmholtz resonator in response to the differences in pre-filtered noise versus filtered noise.

Abstract: Acoustic system for leak detection. The system includes a disk-shaped probe for insertion into fluid flowing within a pipe. The probe has a convex front surface facing in the flow direction and a substantially flat rear surface. The probe further includes wheels to engage a pipe wall to maintain the probe's orientation within the pipe.
