Publication number: 20170356870Abstract: A remote terminal unit for use in monitoring a metallic pipeline can take an electrical measurement at the pipe and transmit the measurement in a modulated signal to a main measurement unit located along the pipe and distant from the remote terminal unit. The electrical measurement is taken at regular time intervals between a reference electrode electrically connected to the pipe and a coupon composed of a sacrificial corrosion material in order to monitor the pipe for possible corrosion. The electrical measurement is modulated with a low frequency carrier signal for transmission along the pipe, eliminating the need to take the measurements directly at physical locations along the pipe.Type: ApplicationFiled: June 14, 2016Publication date: December 14, 2017Inventors: Ziyad H.

Publication number: 20030001556Abstract: A method of electronically isolating a conductor by sensing a current signal in the conductor, adjusting the current signal to yield an adjusted signal, and applying the adjusted signal to the conductor to oppose the current signal. Amplifying the signal, as well as phase-shifting the signal may adjust the current signal. The current signal may be sensed using magnetic induction, and the adjusted signal applied to the conductor using magnetic induction as well. The method is carried out using a clamping device that can further evaluate an environment of the conductor, by randomly changing a magnitude and phase of a test signal applied to the conductor, and examining a received signal in response to the changes. A tracking error in the adjusted signal can be handled by predicting a next required phase shift. Prediction coefficients can be calculated utilizing a least means square algorithm. The invention is particularly applicable to the location of obscured (e.g.Type: ApplicationFiled: June 26, 2001Publication date: January 2, 2003Applicant: 3M Innovative Properties CompanyInventors: Ziyad H.

Patent number: 5471143Abstract: An apparatus for locating obscured conduits, such as buried cables, employs a novel signal processing technique to increase the sensitivity of the apparatus, particularly in congested areas. The cable locating apparatus is similar to prior art dual-peak detection devices which compare signals from two parallel induction coils, but a phase shift is introduced into one of the signals prior to the comparison. This phase shift serves to minimize the effects of side minima in the response curve of prior art dual-peak devices. This effect is enhanced by adding a gain mismatch to the two detected signals. The locator preferably operates with analog signals to reduce expense.Type: GrantFiled: January 29, 1993Date of Patent: November 28, 1995Assignee: Minnesota Mining and Manufacturing Co.Inventor: Ziyad H.
