    摘要: A magnetic position sensor having at least one magnetic field sensor including a solidified layer of GMR nanowire carrier fluid formed on a substrate material. The solidified layer of carrier fluid has (i) discrete GMR nanowires each having a diameter of less than about 0.5 um and a length less than about 250 um; and (ii) a concentration of GMR nanowires in the dried layer between about 0.001 and about 10 percent by weight of the solution. The position sensor further includes a detection circuit capable of detecting a change in resistance of the magnetic field sensor.

    摘要: A cured-in-place-pipe (CIPP) liner inspection system used to inspect a resin level in a CIPP liner that has been impregnated with resin using an inspection chamber having an optical sensor. The CIPP liner inspection system is also used to identify zones within an installed CIPP liner having lower mechanical strength due to inadequate distribution of resin using a robotic unit having an optical sensor. The optical sensor measures an optical property, which is used to determine a resin level or a mechanical property based on predetermined correlations between the optical property and the resin level and predetermined correlations between the optical property and the mechanical property.

    摘要: A chipless RFID tag system having a transmitter sending an input signal and a tag substrate. An ID generation circuit on the tag relies on microstrip transmission line patterns which are pre-designed to generate a unique code. The ID generating circuit may be designed based upon the transmission line properties, including signal delay, and/or reflection, and/or phase change. The tag may be formed on a flexible substrate having at least one microstrip and the microstrip having a first portion with a first impedance and a second portion with a second impedance different from the first impedance. The tag may further include a microstrip antenna for communication with the transmitter and a receiver system. The tag may also include sensors for detection of desired substances of interest. The system may further include a receiver detecting at least two reflections from an interface of first and second impedances and identifying relative time domain positions of the reflections to one another.

    摘要: A method of surveying the condition of an underground conduit by positioning a propelled carriage assembly within the underground conduit. The carriage assembly includes (i) at least one transmitter/receiver unit capable of transmitting a pulsed signal toward at least a portion of an inner wall of the conduit, and (ii) a secondary sensor positioned on the carriage assembly. The data derived from the pulsed signal at a given lateral location within an underground conduit is read as is a secondary sensor condition derived from secondary sensor data taken at the given lateral location. Then it is determined whether the secondary sensor condition indicates a basis for a false void detection by the data derived from the pulsed signal and if the basis for false void detection exists, providing an indication of such basis.

    摘要: A corrosion inhibiting structure includes a mineral tubule having a first end, a second end, and a lumen extending from the first end to the second end. The lumen terminates in a first opening at the first end and a second opening at the second end. The corrosion inhibiting structure also includes an anticorrosion deposit disposed within the lumen, and first and second precipitate stoppers covering the first and second openings, respectively. A coating composition includes a population of corrosion inhibiting structures and a coating material. A method of inhibiting corrosion includes loading anticorrosion agent deposits into lumens, forming stoppers at first and second openings by mixing loaded mineral tubules with a solution containing a predetermined concentration of transition metal ions, mixing the loaded mineral tubules having stoppers with a coating material to form a composite material, and applying the composite material to a metal surface.
